Description

The present invention relates to a treatment bag-like body that is attached to a patient suffering from an infectious disease, for example, to perform treatment.

Conventionally, various measures have been taken to prevent secondary infections caused by contact with patients infected with bacteria or viruses. For example, JP 2010-269121 A (Patent Document 1) proposes a ventilation booth aimed at preventing hospital infections caused by airborne microorganisms such as airborne bacteria and viruses released from infected or suspected infected patients.

The ventilation booth described in Patent Document 1 includes an enclosure that covers the head area of the patient, a frame assembly that supports the enclosure, and a blower that can suck air from within the booth. This blower is equipped with a filter that purifies the air, and as the air in the booth is ventilated, airborne bacteria and viruses released by the patient are captured by the filter, preventing secondary infection (hospital infection).

JP 2010-269121 A

However, while the ventilation booth described in Patent Document 1 can prevent secondary infection of other hospitalized patients, it does not prevent secondary infection of medical staff, as doctors and nurses who treat patients must enter the booth. In particular, when performing procedures such as intubating and extubating a patient's trachea, medical staff are at high risk of becoming infected with bacteria or viruses carried by the patient.

In addition, the ventilation booth described in Patent Document 1 is equipped with an enclosure, a frame assembly, a blower, etc., and therefore tends to be relatively large, and there has been a demand for a booth that is superior in terms of transportation, storage, handling, cost, etc.

The problem to be solved by the present invention is to provide a simple and novel bag-shaped body for treatment that can prevent infection in medical personnel during treatment.

The following describes preferred embodiments for understanding the present invention. However, each embodiment described below is merely an example, and may be combined with one another as appropriate. The multiple components described in each embodiment may be recognized and used independently as far as possible, and may also be combined with any of the components described in another embodiment as appropriate. As a result, the present invention is not limited to the embodiments described below, and various alternative embodiments may be realized.

The first aspect is a surgical bag-like body that forms an internal space capable of accommodating the human head, has an opening large enough for the head to pass through, and at least a portion of the opening is provided with a first constriction sealing portion and a second constriction sealing portion as constriction sealing portions for narrowing the opening amount, thereby enabling a two-stage sealing operation.

The treatment bag of this embodiment is placed over the patient's head during treatment to narrow the opening, thereby preventing the spread of bacteria and viruses carried by the patient to the outside and preventing infection of medical personnel. In particular, this embodiment only requires a size large enough to accommodate the head of a human body, so it does not need to be large like ventilation booths of conventional construction, making it easy to transport, store, and handle, and reducing manufacturing costs. In addition, by using a two-stage sealing structure at the opening, it is possible to perform temporary and permanent fastening at the opening, or to seal the opening more reliably.

The second aspect is a treatment bag-like body according to the first aspect, in which the first constriction sealing portion is a temporary fastening portion that can be repeatedly fastened, while the second constriction sealing portion is a permanent fastening portion that has a higher degree of fastening or adhesion than the first constriction sealing portion.

With this embodiment of the treatment bag, the opening of the opening portion can be narrowed, temporarily secured by the first constriction sealing portion, and then permanently secured by the second constriction sealing portion. In particular, since the temporary securing by the first constriction sealing portion can be repeatedly secured, it is possible to, for example, redo the temporary securing as necessary to accurately determine the position, etc., and then perform the permanent securing to perform reliable constriction and sealing.

The third aspect is a treatment bag-like body that forms an internal space capable of accommodating the head of a human body and allows the interior to be observed, and in an opening portion large enough for the head to pass through, a slit-like cut is provided that extends from the opening edge extending in the circumferential direction toward the bottom of the bag, and a closing seal is provided in the portion where the cut is formed, which closes the cut by fixing both circumferential side edges on either side of the cut to each other.

According to this embodiment of the treatment bag-like body, when the human head is placed inside the bag-like body, the opening can be opened wide by the slit-like cut. In addition, after the human head is placed inside the bag-like body, the tools required for treatment can be easily inserted and removed from the bag-like body through the cut.

The fourth aspect is a treatment bag-like body according to the third aspect, in which the closure seal includes a first closure seal consisting of a temporary fastening portion that can be repeatedly fastened, and a second closure seal consisting of a permanent fastening portion that has a higher degree of fastening or adhesion than the first closure seal.

With this treatment bag-like body, the incision can be closed reliably by, for example, redoing the temporary fastening with the first closure seal as necessary and then permanently fastening it in an accurately positioned state. In addition, for example, when the temporary fastening is in a state with the first closure seal, it is also possible to repeatedly open the incision and insert the necessary treatment tools into the bag each time.

The fifth aspect is a treatment bag-like body according to the third or fourth aspect, which has a bag-like body structure in which a lower sheet-like portion and an upper sheet-like portion that overlap each other are connected around the periphery except for the opening, and the opening edge of the lower sheet-like portion has the notch provided at a position away from the center in the opening width direction toward one end side.

In the treatment bag of this embodiment, the notch is provided at a position away from the center of the opening width toward one end of the opening, so that, for example, the notch can be provided at a position away from the location where the human head is accommodated toward one end of the bag.

The sixth aspect is a treatment bag-like body that forms an internal space capable of accommodating a human head and allows the interior to be observed, and in the opening formed to a size that allows the head to pass through, an upper sheet-like portion located in front of the human head in a supine position is provided with a fastening portion that holds the opening side end portions of the upper sheet-like portion in an overlapping state on both sides in the opening width direction so that the upper sheet-like portion is folded in a mountain fold at the middle portion in the opening width direction and held in a shape that protrudes toward the surface side.

According to this embodiment of the treatment bag-like body, the strength of the bag-like body is increased at the area where the upper sheet-like portion is held in an overlapping state by the fastening portion, and the bag-like body is held in a protruding shape toward the surface side, making it possible to form a tent-shaped space inside the bag in front of the face of a patient in a supine position. Therefore, this space inside the bag can be used to secure a treatment area, for example, when inserting or extubating a tube into the patient's trachea.

The seventh aspect is the treatment bag-like body according to the sixth aspect, in which the fastening portion is provided with a hook-and-loop fastener.

With this type of treatment bag, the hook-and-loop fastener can be redone as necessary, making it possible to adjust the bag-like space formed in front of the patient's face to the desired shape. In addition, the strength of the hook-and-loop fastener components can be used to reinforce the bag, improving the ease of folding and maintaining the stable mountain-folded state.

The eighth aspect is a treatment bag-like body that forms an internal space capable of accommodating the head of a human body and allows the interior to be observed, and has a glove-like portion extending from the surface of the bag-like body toward the internal space, and an arm-insertion opening formed on the surface of the bag-like body, which serves as an opening for inserting the arm into the glove-like portion, has a ring body harder than the bag-like body attached around it.

With this type of treatment bag, even if the bag body is soft, the arm opening is maintained in a ring shape, making it easy for the practitioner to insert their arm into the glove-like portion.

The ninth aspect is a treatment bag-like body according to the eighth aspect, in which the ring body is fixedly provided at the arm-insertion opening of the bag-like body, and the glove-like portion formed separately from the bag-like body is attached to the ring body at the opening end where the arm is inserted.

The treatment bag of this embodiment can use a glove-like portion formed separately from the bag-like main body, making manufacturing easier. It also improves the design freedom of the bag-like main body and the glove-like portion.

The tenth aspect is the treatment bag-like body according to the ninth aspect, in which the opening end of the glove-like portion is an elastic opening end that is elastically squeezed to a size smaller than the size of the ring body, and the elastic opening end is elastically hooked and attached to the ring body.

With this type of treatment bag, the glove-like portion can be easily attached to the ring of the bag body.

The eleventh aspect is a treatment bag-like body that forms an internal space capable of accommodating the head of a human body, and allows the inside to be observed. The treatment bag-like body has a lower sheet-like part and an upper sheet-like part that constitute a bag-like body having an opening large enough for the head to pass through. The upper sheet-like part is provided with a glove-like part that extends from the surface of the bag-like body toward the internal space. On the other hand, the upper sheet-like part has a bottom side from the opening of the glove-like part, and the lower sheet-like part has a bottom side from the head accommodation area, and a drooping part that folds downward and hangs down is set. These drooping parts of the upper sheet-like part and the lower sheet-like part form a pocket-like part in the internal space at the bottom side of the bag-like body when the practitioner inserts his/her hand into the glove-like part.

According to the treatment bag of this embodiment, for example, the tools necessary for treatment can be stored in the pocket-like portion beforehand, and the tools can be taken out of the pocket-like portion and used during treatment. In addition, by storing items that are temporarily or ultimately no longer needed during treatment in the pocket-like portion, it is possible to prevent the items from getting in the way of treatment.

The twelfth aspect is a treatment bag-like body that forms an internal space capable of accommodating a human head, and allows the interior to be observed, in which the set position of the center of the body axis of the human head accommodated in the internal space is offset from the center to one side in the width direction of the internal space, and a service space is provided on the other side of the internal space from the center in the width direction, positioned to the side of the accommodated human head.

With this type of treatment bag-shaped body, by providing a service space, for example, when various devices for treating a patient are placed on either the left or right side of the patient, it is possible to secure space for handling tubes connecting the patient to the devices, to use the service space to place treatment tools, and to efficiently secure space for the practitioner to perform treatment work.

The thirteenth aspect is a treatment bag-like body that forms an internal space capable of accommodating the human head and allows the interior to be observed, and the bag-like body has an opening large enough for the head to pass through, and is provided with a tube insertion portion, and a reinforcing member is attached to the outer periphery of the tube insertion portion, allowing the tube to be inserted by breaking through the tube insertion portion.

With this type of treatment bag-shaped body, the reinforcing member can increase the strength of the outer periphery of the tube insertion portion, making it easier to insert the tube into the tube insertion portion of the bag-shaped body and preventing problems such as the periphery of the tube insertion portion tearing open.

In the fourteenth aspect, in the treatment bag-like body according to the thirteenth aspect, the reinforcing member has an insertion hole, and the tube insertion portion made of the bag-like body and/or a separate sheet is superimposed on the insertion hole so as to cover it, and the tube insertion portion has a fragile portion such as a perforation formed therein.

According to the present embodiment of the treatment bag-shaped body, the tube insertion portion is provided with a weak portion, which makes it easier to insert the tube. In particular, since the weak portion is formed of perforations or the like, the tube insertion portion after the tube is inserted remains in a pleated shape and comes into contact with the surface of the tube, which can maintain or improve the closure of the tube insertion portion.

In the fifteenth aspect, in the treatment bag-like body according to the first to fourteenth aspects, the opening formed to a size that allows the head to pass through is provided with a positioning adhesive surface that can be attached to the surface of the human body.

According to the treatment bag of this embodiment, by adhering the opening of the bag to the surface of the human body with the positioning adhesive surface, it is possible to prevent misalignment between the human body and the bag, and to reduce the gap between the opening and the human body, thereby preventing the spread of bacteria or viruses to the outside through the gap. The positioning adhesive surface of this embodiment can also constitute, for example, the second constriction sealing portion in the first embodiment.

The present invention makes it possible to provide a simple and novel treatment bag that can prevent infection in medical personnel during treatment.

In order to clarify the present invention more specifically, the following embodiment of the present invention will be described in detail with reference to the drawings.

First, FIG. 1 shows a treatment bag 10 as one embodiment of the present invention. This treatment bag 10 is used when performing treatments such as intubation and extubation of a ventilator tube or tracheal tube on a patient who is infected with or suspected of being infected with an infectious disease, and is intended to prevent secondary infection from the patient to the medical staff. In the following description, the front-to-rear direction refers to the bottom-up direction in FIG. 1, the front refers to the bottom side in FIG. 1 where the patient is positioned relative to the treatment bag 10, and the rear refers to the top side in FIG. 1 where the medical staff is positioned relative to the treatment bag 10. In addition, the left-to-right direction refers to the left-to-right direction in FIG. 1.

More specifically, the treatment bag 10 has a bag-shaped main body 12 that is rectangular in plan view as a whole. That is, the bag-shaped main body 12 has an upper sheet-shaped portion 14 and a lower sheet-shaped portion 16 that overlap each other, as shown in Figures 2(a) and (b). The upper sheet-shaped portion 14 and the lower sheet-shaped portion 16 are connected on three sides around the periphery, except for the opening portion 18. In this embodiment, the opening portion 18 is provided in the front of the treatment bag 10 (bag-shaped main body 12), and the upper sheet-shaped portion 14 and the lower sheet-shaped portion 16 are connected on three sides, the rear and both the left and right sides. Therefore, the rear side of the treatment bag 10 (bag-shaped main body 12) is the bottom side of the bag. Note that Figure 2(a) shows the outer surface side of the upper sheet-like portion 14 (the side that will become the outer surface when the bag-shaped main body 12 is constructed), and Figure 2(b) shows the inner surface side of the lower sheet-like portion 16 (the side that will become the inner surface when the bag-shaped main body 12 is constructed).

The treatment bag 10 (bag-shaped main body 12) is made of soft resin such as polyethylene, and is preferably formed of a transparent synthetic resin sheet. The treatment bag 10 (bag-shaped main body 12) may be colorless and transparent or colored and may have a visible light transmittance of 80% or more, so long as the inside can be observed. As shown in FIG. 8, which will be described later, the internal space 20 (between the upper sheet-shaped part 14 and the lower sheet-shaped part 16 in the inflated state) in the treatment bag 10 (bag-shaped main body 12) is large enough to accommodate the head of a human body (patient). The opening 18 is large enough for the patient's head to pass through, and the patient's head is accommodated in the internal space 20 through the opening 18.

In addition, a hook-and-loop fastener 22 and a double-sided tape 24 are provided on the inner surface of the opening 18 of the treatment bag-like body 10 (bag-like main body 12). The hook-and-loop fastener 22 and the double-sided tape 24 may be conventionally known, that is, the hook-and-loop fastener 22 has, for example, a first hook-and-loop fastener 22a that is raised in a hook shape and that is fixed to each other, and a second hook-and-loop fastener 22b that is raised in a loop shape. In addition, the double-sided tape 24 is configured such that the inner surface of the bag-like main body 12 and a release sheet are attached to both sides of the adhesive layer, in other words, the release sheet is attached to the inner surface of the bag-like main body 12 via the adhesive layer. The adhesive surface is exposed by peeling off the release sheet. In addition, instead of the release sheet, an adhesive bandage having a release sheet attached to one side having adhesiveness may be attached to the adhesive layer on the non-adhesive side, and the adhesive surface of the adhesive bandage may be exposed by peeling off the release sheet. This can improve breathability and prevent skin rashes of the patient. However, instead of the double-sided tape 24, it is also possible to use an adhesive bandage that has adhesiveness on both sides, and a release sheet may be attached to such an adhesive bandage.

In this embodiment, as described below, multiple double-sided tapes 24, i.e., multiple release sheets, are provided, and these multiple release sheets may, for example, have numbers indicating the order in which they should be removed or arrows indicating the direction in which they should be removed written on one end. In addition, a tab may be provided on one end to make these release sheets easier to remove.

Furthermore, in this embodiment, a first hook-and-loop fastener 22a and a second hook-and-loop fastener 22b are fixed to each other by adhesion or the like at a position on the inner surface side of the upper sheet-like portion 14, spaced some distance rearward from the front edge that forms the opening edge. In particular, in this embodiment, the first hook-and-loop fastener 22a and the second hook-and-loop fastener 22b are each formed with a left-right dimension that is less than half the left-right dimension of the bag-shaped main body 12 (upper sheet-like portion 14), and are provided adjacent to each other in the left-right direction.

The left-right center of the arrangement area of the first and second hook-and-loop fasteners 22a, 22b is set to be biased to the right of the left-right center of the upper sheet-like portion 14. In other words, in the upper sheet-like portion 14, the first hook-and-loop fastener 22a is provided in the right-side area, the second hook-and-loop fastener 22b is provided in the left-right center area, and an area where neither the first hook-and-loop fastener 22a nor the second hook-and-loop fastener 22b is provided is provided on the left side. Note that the first hook-and-loop fastener 22a and the second hook-and-loop fastener 22b are both formed as substantially rectangular bands, but in this embodiment, the width dimension of the first hook-and-loop fastener 22a is smaller than the width dimension (front-back dimension) of the second hook-and-loop fastener 22b. This allows for a certain degree of misalignment between the first and second hook-and-loop fasteners 22a and 22b when the first and second hook-and-loop fasteners 22a and 22b are attached, and makes it easier to peel the first and second hook-and-loop fasteners 22a and 22b apart. Furthermore, because the hook-shaped first hook-and-loop fastener 22a is narrow, the risk of the first hook-and-loop fastener 22a coming into contact with the patient and causing pain to the patient can be reduced.

In this embodiment, three double-sided tapes 24 (i.e., first to third double-sided tapes 24a to 24c) are provided around the periphery of the opening 18 of the bag-shaped main body 12. These first to third double-sided tapes 24a to 24c are provided on the inner surface side of the lower sheet-like portion 16. The second double-sided tape 24b is provided across the upper sheet-like portion 14 and the lower sheet-like portion 16 so as to be folded back at the right end of the bag-shaped main body 12, and is provided over the right part of the lower sheet-like portion 16 and over substantially the entire length of the upper sheet-like portion 14 in the left-right direction.

In particular, in this embodiment, the left-right center of the area in which the first to third double-sided tapes 24a to 24c are provided in the lower sheet-like portion 16 is set to be biased to the right of the left-right center of the lower sheet-like portion 16, and there is an area to the left of the third double-sided tape 24c where no double-sided tape is provided. Furthermore, the first to third double-sided tapes 24a to 24c are provided at approximately equal positions in the front-to-rear direction in the bag-shaped main body 12.

Furthermore, in the lower sheet-like portion 16, a slit-like cut 28 is provided to the left of the third double-sided tape 24c, extending from the front edge, which is the opening edge, toward the rear, which is the bottom side of the bag. In this embodiment, the cut 28 is provided in the opening portion 18 of the bag-shaped main body 12, between the left end, which is one end in the opening width direction, and the left-right center. In other words, the cut 28 is provided in a position away from the left-right center toward the left end, and away from the left end toward the center. This cut 28 extends approximately straight with a certain dimension in the front-rear direction, and is formed with a front-rear dimension that is, for example, about 1/3 of the front-rear dimension of the lower sheet-like portion 16.

The lower sheet-like portion 16 is provided with a first hook-and-loop fastener 30a and a second hook-and-loop fastener 30b, which are fixed to each other, on both sides of the cut 28 in the left-right direction. The first and second hook-and-loop fasteners 30a, 30b extend from the front edge of the lower sheet-like portion 16 to the rear of the cut 28, and the rear ends of the first and second hook-and-loop fasteners 30a, 30b have portions that extend in the left-right direction. In this embodiment, the first hook-and-loop fastener 30a, which is raised in a hook shape, is provided to the left of the cut 28 at a certain distance, and the second hook-and-loop fastener 30b, which is raised in a loop shape, is provided to the right of the cut 28 at a certain distance. In particular, in this embodiment, in the pre-use state shown in FIG. 1, the second hook-and-loop fastener 22b provided on the upper sheet-like portion 14 and the second hook-and-loop fastener 30b provided on the lower sheet-like portion 16 are partially overlapped in the vertical direction. Here, because the hook-and-loop fasteners that overlap in the vertical direction are both second hook-and-loop fasteners 22b, 30b that are raised in a loop shape, it is possible to prevent the upper and lower hook-and-loop fasteners (second hook-and-loop fasteners 22b, 30b) from unintentionally adhering to each other before use.

In addition, in this embodiment, the first hook-and-loop fastener 30a is formed with a smaller width than the second hook-and-loop fastener 30b. This allows a certain degree of misalignment between the first hook-and-loop fastener 30a and the second hook-and-loop fastener 30b when the first hook-and-loop fastener 30a and the second hook-and-loop fastener 30b are fixed together, and makes it easier to peel the first hook-and-loop fastener 30a and the second hook-and-loop fastener 30b apart. Furthermore, since the hook-and-loop fastener 30a is formed with a narrow width, the risk of the first hook-and-loop fastener 30a coming into contact with the patient and causing pain to the patient can be reduced. In particular, by providing the hook-and-loop fastener 30a on the outside (left side) and the loop-and-loop fastener 30b on the patient side (center side), the risk of the first hook-and-loop fastener 30a coming into contact with the patient and causing pain to the patient can be further reduced.

Furthermore, a double-sided tape 32 extending in the front-rear direction is provided between the cutout 28 and the second hook-and-loop fastener 30b in the left-right direction. The double-sided tape 32 has a front-rear dimension that is approximately equal to that of the cutout 28. As with the double-sided tape 24 described above, an adhesive bandage may be attached to the double-sided tape 32 instead of a release sheet, and an adhesive bandage having adhesive properties on both sides may be used instead of the double-sided tape 32.

Furthermore, the bag-shaped body 12 has a tube insertion section 34 in the middle in the front-rear direction, through which a tube is inserted. The tube inserted into the tube insertion section 34 may be, for example, a ventilator tube or tracheal tube that is intubated into or removed from the patient's trachea, or a suction tube that draws in air from the treatment bag-shaped body 10.

In this embodiment, three tube insertion portions 34 are provided in the middle of the upper sheet-like portion 14 in the front-rear direction, one trachea insertion portion 34a is provided at a position offset to the right of the center of the upper sheet-like portion 14 in the left-right direction, and two suction insertion portions 34b, 34c are provided at a position offset slightly to the left of the center of the upper sheet-like portion 14 in the left-right direction. The two suction insertion portions 34b, 34c are spaced apart from each other in the front-rear direction, and in this embodiment, the rear suction insertion portion 34b is for a suction tube with a larger diameter than the front suction insertion portion 34c. The front suction insertion portion 34c is provided behind the first and second hook-and-loop fasteners 30a, 30b provided on the lower sheet-like portion 16, and the trachea insertion portion 34a is provided behind the rear suction insertion portion 34b. In addition, since the three tube insertion portions 34 (trachea insertion portion 34a, suction insertion portions 34b, 34c) all have approximately the same structure, only trachea insertion portion 34a will be explained with reference to FIG. 3, and a detailed explanation of suction insertion portions 34b, 34c will be omitted.

The trachea insertion portion 34a of this embodiment is configured to include a circular hole 36 that penetrates the upper sheet-like portion 14 in the thickness direction, and a separate sheet 38 that is superimposed on the outer surface side of the upper sheet-like portion 14. The separate sheet 38 is a substantially rectangular sheet, and is made of the same soft synthetic resin as the upper sheet-like portion 14. The separate sheet 38 is formed with a fragile portion 40 composed of a cross perforation, and the upper sheet-like portion 14 and the separate sheet 38 are superimposed so that the fragile portion 40 is located within the circular hole 36. As a result, when an artificial respirator tube or a tracheal tube is inserted into the trachea insertion portion 34a, the artificial respirator tube or the tracheal tube is inserted by breaking through the fragile portion 40.

Then, in the tube insertion portion 34 (trachea insertion portion 34a) consisting of the upper sheet-like portion 14 and the separate sheet 38, a reinforcing member 42 is attached so as to cover the outer periphery of the fragile portion 40. That is, the reinforcing member 42 is in the form of a plate having an insertion hole 44 penetrating in the thickness direction, and is formed of a synthetic resin such as polypropylene having a strength greater than that of the upper sheet-like portion 14 and the separate sheet 38. The reinforcing member 42 is provided between the upper sheet-like portion 14 and the separate sheet 38, and is arranged so that the fragile portion 40 is located within the insertion hole 44. That is, the tube insertion portion 34 of this embodiment is configured from the inside to have a three-layer structure consisting of the upper sheet-like portion 14, the reinforcing member 42, and the separate sheet 38.

In this embodiment, the reinforcing member 42 is rectangular and approximately the same size as the separate sheet 38, and the reinforcing member 42 and the separate sheet 38 are fixed to each other by thermal welding. In particular, in this embodiment, the reinforcing member 42 and the separate sheet 38 are fixed to each other by thermal welding at eight points (points shown in gray in FIG. 3) on the periphery outside the insertion hole 44. It is preferable that such welding points include four points that are the ends of the cross perforations. The reinforcing member 42 and the separate sheet 38 fixed to each other are fixed to the outer surface of the upper sheet-like portion 14 so as to cover the circular hole 36. Note that the method of fixing the reinforcing member 42 and the separate sheet 38 to the upper sheet-like portion 14 is not limited, and may be, for example, welding or adhesion, but in this embodiment, the reinforcing member 42 and the separate sheet 38 are fixed to the upper sheet-like portion 14 by attaching tape 46 from the upper side of the separate sheet 38. In FIG. 3, the tape 46 is shown with a two-dot chain line for ease of viewing.

The diameter of the circular hole 36 and the through hole 44, and the size of the fragile part 40 (the length of the perforation) are not limited, but in this embodiment, the diameter of the through hole 44 is slightly larger than the size of the fragile part 40 (the length of the perforation), and the diameter of the circular hole 36 is slightly larger than the diameter of the through hole 44. In addition, in the trachea insertion part 34a, the diameter of the circular hole 36 and the through hole 44, and the size of the fragile part 40 are not limited by the outer diameter of the artificial respirator tube or tracheal tube to be inserted, and may be larger or smaller than the outer diameter of the artificial respirator tube or tracheal tube. The same is true for the suction insertion parts 34b and 34c, and the diameter of the circular hole 36 and the through hole 44, and the size of the fragile part 40 are not limited by the outer diameter of the suction tube inserted into the suction insertion parts 34b and 34c. Furthermore, such tube insertion portion 34 (trachea insertion portion 34a, suction insertion portions 34b, 34c) may be sealed, for example by attaching tape or the like from the outside so as to cover the fragile portion 40, before the tube (ventilator tube 56 or suction tube 64) described below is inserted, thereby preventing the tube or the like from unintentionally breaking through the tube insertion portion (fragile portion) and establishing communication between the inside and outside of the bag-shaped main body 12.

Furthermore, a glove-like portion 48 is provided at the rear portion of the bag-like body 12, extending from the surface of the bag-like body 12 toward the internal space 20. That is, in this embodiment, the glove-like portion 48 is provided on the inner surface of the upper sheet-like portion 14, and an arm-insertion opening 50, which serves as an arm insertion opening into the glove-like portion 48, is formed on the outer surface of the upper sheet-like portion 14, which is the surface of the bag-like body 12, penetrating the upper sheet-like portion 14 in the thickness direction. In this embodiment, a pair of arm-insertion openings 50, 50 are formed rearward of the trachea insertion portion 34a, spaced apart from each other in the left-right direction. In particular, in this embodiment, the left-right center between the pair of arm-insertion openings 50, 50 is biased to the right from the left-right center of the upper sheet-like portion 14.

A glove-like portion 48, 48 is provided for each of the pair of arm-insertion openings 50, 50. The glove-like portion 48 has a certain length in the front-rear direction, and is formed with a length dimension that not only allows five fingers to be inserted at the tip, but also covers at least the forearm to some extent. In this embodiment, as shown in Figure 4, the glove-like portion 48 is formed separately from the upper sheet-like portion 14, and the opening end of the glove-like portion 48 through which the arm is inserted (the upper end opening in Figure 4) is attached to the arm-insertion opening 50 provided in the upper sheet-like portion 14.

Specifically, a ring body 52 that is harder than the upper sheet-like portion 14 is provided around the arm-insertion opening 50 in the upper sheet-like portion 14. In this embodiment, the ring body 52 is fixed to the outer surface side of the upper sheet-like portion 14. The method for fixing the ring body 52 to the outer surface side of the upper sheet-like portion 14 is not limited, but for example, the ring body 52 can be fixed to the outer surface side of the upper sheet-like portion 14 by making a cut in the portion of the upper sheet-like portion 14 located on the inner periphery side of the ring body 52, folding it back to the outer surface side of the upper sheet-like portion 14, and heat welding the upper sheet-like portions 14 together with the ring body 52 sandwiched therebetween.

In addition, an elastic ring-shaped member 54 such as a rubber band is provided at the opening end of the glove-shaped portion 48 (the upper end opening in FIG. 4). As a result, the opening end of the glove-shaped portion 48 is an elastic opening end whose opening size is elastically narrowed. For example, the inner diameter dimension φA (see FIG. 4) of the elastic ring-shaped member 54 in its natural state is smaller than the outer diameter dimension φB (see FIG. 1) of the ring body 52. As a result, the elastic ring-shaped member 54 at the opening end of the glove-shaped portion 48 is elastically expanded and hooked onto the ring body 52 to release the deformation, so that the elastic ring-shaped member 54 elastically restores its original shape and the glove-shaped portion 48 is attached to the ring body 52 at the opening end. In particular, by providing the ring body 52 on the outer surface side of the upper sheet-like portion 14, it is possible to easily attach the elastic ring member 54 (glove-like portion 48) to the ring body 52, and when a medical professional inserts his/her arm into the glove-like portion 48, the elastic ring member 54 (glove-like portion 48) is less likely to fall off into the internal space 20.

Furthermore, in this embodiment, both left and right sides of the rear end of the treatment bag 10 are folded upward, and the folded tip is welded to the upper sheet-like portion 14 to form a roughly cylindrical storage space 55. This storage space 55 can store, for example, a rubber band 78 as shown in Figs. 12(a) and (b) described below. Note that in Fig. 1, the portion folded upward and the welded portion of the upper sheet-like portion 14 are shown in gray, and in Fig. 2(a), the portion of the upper sheet-like portion 14 that is folded upward to form the storage space 55 is shown by a two-dot chain line.

The method of using the treatment bag 10 of this embodiment will be described below with reference to Figs. 5 to 9. Fig. 5 shows a patient P as a human body to which the treatment bag 10 is attached. The patient P is either infected with an infectious disease or suspected of being infected, and is connected to an artificial respirator tube 56 and a tube 58 for an IV drip or the like. The patient P is lying in a supine position on a bed B, for example, with the artificial respirator tube 56 extending from the patient P in the direction above his head and the tube 58 extending to the side.

The head H of the patient P is placed in the internal space 20 of the treatment bag 10, and the treatment bag 10 is attached to the patient P. That is, the head H of the patient P is lifted, and the lower sheet-like part 16 is inserted under the head H. At this time, as shown in FIG. 6, the opening part 18 of the treatment bag 10 has a cut 28, so that the opening part 18 can be greatly expanded at the cut 28, and the head H of the patient P can be easily placed in the internal space 20. The head H of the patient P is positioned on the first double-sided tape 24a of the lower sheet-like part 16, and the back of the patient P's neck is overlapped with the first double-sided tape 24a. Here, for example, before inserting the lower sheet-like part 16 under the head H of the patient P, the release sheet of the first double-sided tape 24a may be peeled off so that the first double-sided tape 24a is attached to the back of the patient P's neck when the lower sheet-like part 16 is inserted.

That is, the back of the neck, which is the center of the body axis of the head H of the patient P, is overlapped with the first double-sided tape 24a on the lower sheet-like portion 16, and the center in the left-right direction of this first double-sided tape 24a is biased to one side (right side) from the center in the width direction (left-right direction) of the internal space 20. Therefore, in this embodiment, it is instructed that the position of the center of the body axis of the head H of the patient P contained in the bag-shaped main body 12 is set to be biased to one side (right side) from the center in the width direction of the internal space 20.

As described above, in this embodiment, the center of the body axis of the head H of the patient P is located on one side (right side) of the center of the width direction of the bag in the treatment bag 10. In other words, the service space 60 (see FIG. 7) is provided on the other side (left side) of the center of the width direction of the bag in the treatment bag 10, located to the side of the head H of the patient P. By providing such a service space 60, interference between the practitioner and the treatment bag 10 is suppressed, making it easy to perform treatments such as intubation and extubation of the trachea. In FIG. 1, the service space forming area 62 that becomes the service space 60 during use is shown by a virtual two-dot chain line, but this does not limit the area that becomes the service space 60.

Next, as shown in FIG. 7, the opening 18 is sealed. At that time, the opening 18 of the upper sheet-like portion 14 is folded in a mountain fold in front of the patient P in a supine position. Specifically, the portion of the opening 18 of the upper sheet-like portion 14 located in front of the patient P is folded in a mountain fold, and the first hook-and-loop fastener 22a and the second hook-and-loop fastener 22b are fixed to each other. Since this fixing is achieved by hook-and-loop fasteners, it is releasable and can be fixed repeatedly.

The first hook-and-loop fastener 22a and the second hook-and-loop fastener 22b are fixed to the opening 18 of the upper sheet-like portion 14, so that the left portion of the upper sheet-like portion 14 is pulled to the right. As a result, the left portion of the lower sheet-like portion 16, which is continuous with the left portion of the upper sheet-like portion 14, is also pulled, and the portion of the lower sheet-like portion 16 that was located to the left of the cut 28 moves to the upper side of the bag-like main body 12, so that the first hook-and-loop fastener 30a and the second hook-and-loop fastener 30b that were located to the left and right of the cut 28 face each other in the vertical direction, and the cut 28 is positioned to the left of the bag-like main body 12.

Here, when the head H of the patient P is accommodated in the bag-shaped main body 12, the practitioner's arm is inserted into the glove-shaped portion 48, and the artificial respirator tube 56 is inserted into the tube insertion portion 34 (tracheal insertion portion 34a) as described below, so that the arm insertion opening 50 and the tracheal insertion portion 34a, which are the openings of the glove-shaped portion 48, are lifted upward as shown in Figures 7 and 8. As a result, in the internal space 20 of the bag-shaped main body 12, a pocket-shaped portion 63 that is bent downward and hangs down is formed on the bottom side (rear side) of the bag from the arm insertion opening 50. That is, in this embodiment, the upper hanging portion 63a constituting the pocket-shaped portion 63 is set on the bottom side of the arm insertion opening 50 in the upper sheet-shaped portion 14, and the lower hanging portion 63b constituting the pocket-shaped portion 63 is set on the bottom side of the head H accommodation area in the lower sheet-shaped portion 16. In FIG. 1, the pocket-shaped portion forming area 63c that becomes the pocket-shaped portion 63 when in use is shown imaginarily by a two-dot chain line, but this does not limit the area that becomes the pocket-shaped portion 63.

Then, through the slit 28, the service space 60 or the pocket-like portion 63 in the bag-shaped main body 12 accommodates tools necessary for treatment, such as a mask or a syringe. In this embodiment, the slit 28 is provided in the portion of the bag-shaped main body 12 where the service space 60 is formed, and tools for treatment can be easily inserted and removed from the service space 60 or the pocket-like portion 63 through the slit 28. Even if tools for treatment are stored in the service space 60, the risk of these tools interfering with the practitioner during treatment can be reduced. In addition, by providing the pocket-like portion 63, tools for treatment that are inserted and removed through the slit 28 and the service space 60 can be stored in the pocket-like portion 63 before treatment, or can be removed from the pocket-like portion 63 during treatment. Note that FIG. 8 shows a state in which a mask is stored in the pocket-like portion 63.

Then, the ventilator tube 56 is cut, for example, at the connector, and the portion connected to the trachea of the patient P is inserted from the inside into the trachea insertion portion 34a of the upper sheet-shaped portion 14. Specifically, as shown in FIG. 9, the ventilator tube 56 breaks through the fragile portion 40 from the inside of the upper sheet-shaped portion 14, and the ventilator tube 56 is inserted into the trachea insertion portion 34a. Thereafter, the ventilator tube 56 is reconnected outside the treatment bag 10, and the supply of oxygen to the patient P is resumed.

Then, after the artificial respirator tube 56 is inserted into the trachea insertion portion 34a, the release sheet of the second double-sided tape 24b is peeled off, and the overlapped second double-sided tape 24b is fixed to each other by folding in a mountain fold. As a result, the opening portion 18 of the bag-shaped main body 12 is sealed with a higher degree of fixation or adhesion than the fixation between the first hook-and-loop fastener 22a and the second hook-and-loop fastener 22b. In this way, when sealing the opening portion 18 of the bag-shaped main body 12 with the first and second hook-and-loop fasteners 22a, 22b and the second double-sided tape 24b, the opening portion 18 of the upper sheet-like portion 14 is folded in a mountain fold, so that the opening amount of the opening portion 18 is narrowed. Then, the narrowing sealing portion for sealing the opening amount narrowed is composed of the hook-and-loop fasteners 22 (the first and second hook-and-loop fasteners 22a, 22b) and the double-sided tape 24, especially the second double-sided tape 24b.

That is, in this embodiment, a two-step sealing operation is possible: sealing by the first constriction sealing portion consisting of the first and second hook-and-loop fasteners 22a and 22b, and sealing by the second constriction sealing portion consisting of the double-sided tape 24, particularly the second double-sided tape 24b. In particular, in this embodiment, the first constriction sealing portion (the first and second hook-and-loop fasteners 22a and 22b) is a temporary fastening portion that can be repeatedly fastened, and the second constriction sealing portion (the second double-sided tape 24b) is a permanent fastening portion that has a higher degree of fastening or adhesion than the first constriction sealing portion, and the second constriction sealing portion is provided on the opening side, i.e., below the first constriction sealing portion. Therefore, the opening portion 18 can be permanently fastened by the second constriction sealing portion while the opening portion 18 is temporarily fastened by the first constriction sealing portion.

When the front part of the head H of the patient P is folded in a mountain fold at the middle part in the opening width direction in the upper sheet-like portion 14 so as to protrude toward the front side, the fastening parts that hold the opening side ends of the upper sheet-like portion 14 in an overlapping state on both sides in the opening width direction (left and right direction) are composed of the first and second hook-and-loop fasteners 22a, 22b and the second double-sided tape 24b.

The left-right center of the area where the first and second hook-and-loop fasteners 22a, 22b and the second double-sided tape 24b are arranged, which maintain the mountain-folded state, is biased to one side (right) from the center in the width direction (left-right direction) of the internal space 20. In addition, the trachea insertion portion 34a, through which the artificial respirator tube 56 extending from the patient P in the overhead direction is inserted, is biased to one side (right) from the center in the left-right direction of the upper sheet-like portion 14, and the area where the pair of arm insertion openings 50, 50 are arranged is also biased to one side (right) from the center in the left-right direction of the upper sheet-like portion 14. In this embodiment, due to these factors, it is instructed that the position of the body axis center of the head H of the patient P accommodated in the bag-like main body 12 is set to be biased to one side (right) from the center in the width direction of the internal space 20.

Furthermore, the tube 58 extending laterally from the patient P is sandwiched above and below the slit 28 and extends to the outside through the slit 28. After the tube 58 is aligned to an appropriate position in the slit 28, the first hook-and-loop fastener 30a and the second hook-and-loop fastener 30b are fastened to each other, thereby closing the slit 28. Since this fastening is achieved by the hook-and-loop fastener, it is releasable and can be repeatedly fastened.

Then, the release sheet of the third double-sided tape 24c on the lower sheet-like portion 16 is peeled off, and the third double-sided tape 24c is superimposed on the second double-sided tape 24b on the upper sheet-like portion 14 and adhered to it. The third double-sided tape 24c may be adhered to, for example, a portion of the upper sheet-like portion 14 that is further rearward than the second double-sided tape 24b.

As described above, by folding the right side of the opening 18 of the upper sheet-like portion 14 in a mountain fold, the left side of the opening 18 of the upper sheet-like portion 14 is pulled to the right, and the left side of the lower sheet-like portion 16 is positioned on the upper side of the bag-like body 12. As a result, when the head H of the patient P is accommodated in the internal space 20 of the bag-like body 12, the third double-sided tape 24c, which will be located on the left side of the bag-like body 12, can be attached to the back surface of the shoulder of the patient P, depending on the physique of the patient P and the extent to which the treatment bag-like body 10 is placed on the patient P. Also, with respect to the second double-sided tape 24b, the portions other than those folded in a mountain fold and fixed to each other can be attached to the front or back surface of the shoulder of the patient P, for example. That is, in this embodiment, the positioning adhesive surface provided in the opening 18 of the bag-like body 12 and capable of being fixed to the surface of the human body (patient P) is configured to include at least one of the first to third double-sided tapes 24a to 24c.

Furthermore, if necessary, the release sheet of the double-sided tape 32 located to the right of the cut 28 is peeled off and adhered to the upper sheet-like portion 14 located above the double-sided tape 32. This allows the cut 28 to be closed with a higher degree of adhesion or closeness than that achieved by the first hook-and-loop fastener 30a and the second hook-and-loop fastener 30b. In other words, in this embodiment, the closing seal that closes the cut 28 by adhering the circumferential side edges sandwiching the cut 28 to each other is composed of the first and second hook-and-loop fasteners 30a, 30b and the double-sided tape 32.

In particular, in this embodiment, the first closure seal, which is a temporary fastening portion that can be repeatedly fastened, is made up of the first and second hook-and-loop fasteners 30a and 30b, and the second closure seal, which is a permanent fastening portion that has a higher degree of fastening or adhesion than the first closure seal, is made up of the double-sided tape 32. When the notch 28 is located at the leftmost position on the bag-shaped main body 12, the second closure seal (double-sided tape 32) is provided closer to the notch 28 (left side) than the first closure seal (first and second hook-and-loop fasteners 30a and 30b), so that the notch 28 can be permanently fastened by the second closure seal while the notch 28 is temporarily fastened by the first closure seal.

Then, as shown in FIG. 10, for example, a suction tube 64 is inserted into one of the suction insertion parts 34b, 34c provided on the bag-shaped body 12. This suction tube 64 is connected to a negative pressure source, and the air in the internal space 20 of the treatment bag-shaped body 10 can be sucked through the suction tube 64. By inserting the suction tube 64, the air in the internal space 20 of the treatment bag-shaped body 10 can be sucked at an appropriate timing. The timing of sucking the air in the internal space 20 through the suction tube 64 is not limited, but it is preferable to perform it, for example, when intubating or extubating the artificial respirator tube or tracheal tube. That is, after extubating the artificial respirator tube or tracheal tube, it is considered that bacteria, viruses, etc. carried by the patient P are attached to these artificial respirator tubes or tracheal tubes. In addition, when intubating or extubating the artificial respirator tube or tracheal tube, vomiting or coughing due to a reflex reaction may occur, and it is considered that bacteria, viruses, etc. are attached to the vomit or droplets. In particular, since the patient P may be conscious during extubation, it is conceivable that the patient may cough. Therefore, by sucking the air from the internal space 20 of the treatment bag 10 at these times, bacteria and viruses that have spread in the internal space 20 of the treatment bag 10 can be captured, reducing the risk of secondary infection of medical personnel.

In particular, in this embodiment, the suction insertion portions 34b and 34c through which the suction tube 64 is inserted are provided at a position biased to the left of the center in the left-right direction of the bag-shaped main body 12, i.e., the suction tube 64 is inserted at the service space 60 or at a position relatively close to the service space 60. Therefore, even when the suction tube 64 is inserted into the bag-shaped main body 12, the effect on the treatment by the practitioner is kept small.

In the treatment bag 10 of this embodiment, which has the above-mentioned structure, the opening 18 is sealed in two stages by the first narrowing sealing portion (first and second hook-and-loop fasteners 22a, 22b) and the second narrowing sealing portion (second double-sided tape 24b) with the opening narrowed, so that the opening 18 is sealed more reliably and bacteria and viruses carried by the patient P are prevented from spreading to the outside. In addition, the treatment bag 10 prevents bacteria and viruses from spreading to the outside while avoiding the need for larger size as in conventional structures, making it easier to transport and store, and achieving improved handleability and reduced manufacturing costs.

In particular, the first constriction sealing portion is composed of the first and second hook-and-loop fasteners 22a, 22b, and is a temporary fastening portion that can be repeatedly fastened. Therefore, if there is a problem with the sealing of the opening portion 18, for example, the fastening of the first and second hook-and-loop fasteners 22a, 22b can be released, and the opening portion 18 can be sealed again. In addition, the second constriction sealing portion (second double-sided tape 24b) is a permanent fastening portion that has a higher degree of fastening or adhesion than the first constriction sealing portion, so that after the opening portion 18 is temporarily fastened by the first constriction sealing portion, the opening portion 18 can be permanently fastened by the second constriction sealing portion.

In addition, in this embodiment, a slit 28 is provided on the side of the treatment bag 10 during use, and a closing seal (first and second hook-and-loop fasteners 30a, 30b and double-sided tape 32) is provided to close the slit 28 by fixing both circumferential side edges sandwiching the slit 28 to each other. This allows the tools required for treatment to be inserted and removed from the treatment bag 10 through the slit 28, and the tube 58 connected to the patient P can be extended laterally to the outside of the treatment bag 10. As a result, the position of the tube 58 in the slit 28 can be appropriately set, and the position of the tube 58 delivered to the outside from the treatment bag 10 can be set with more freedom. After the tools are inserted and removed or the tube 58 is extended laterally, the slit 28 can be closed by the closing seal to prevent the spread of bacteria and viruses to the outside.

Furthermore, since the above-mentioned closing seal includes the first and second hook-and-loop fasteners 30a, 30b as a first closing seal consisting of a temporary fastening portion that can be repeatedly fastened, and the double-sided tape 32 as a second closing seal consisting of a permanent fastening portion that has a higher degree of fastening or adhesion than the first closing seal, the first closing seal maintains the closed state of the notch 28, and if there is no problem with such closure, an even higher degree of closure of the notch 28 can be achieved by the second closing seal.

These cuts 28 are provided in the lower sheet-like portion 16 before use. That is, the opening portion 18 of the upper sheet-like portion 14 has a smaller left-right width dimension due to the portion located in front of the patient P being folded in a mountain fold shape, but by providing the cuts 28 in the lower sheet-like portion 16, the left-right width dimension of the opening portion 18 in the upper sheet-like portion 14 can be sufficiently secured, and a mountain fold-like portion can be stably provided in front of the patient P. In particular, the cuts 28 in this embodiment are provided avoiding the left end portion and the left-right center of the bag-like main body 12, so that when the head H of the patient P is accommodated in the internal space 20 of the bag-like main body 12, the cuts 28 are prevented from being located under the head H. In addition, when a mountain fold-like portion is provided in the upper sheet-like portion 14, the cuts 28 can be stably positioned to the side of the bag-like main body 12.

In this embodiment, the first and second hook-and-loop fasteners 22a, 22b and the second double-sided tape 24b are provided in the opening 18 of the upper sheet-like portion 14 in the portion located in front of the patient P, and are overlapped and fixed when folded in a mountain fold, so that they are maintained in a shape protruding on the surface side. This allows stable intubation of the artificial respirator tube 56 or a tracheal tube (not shown) into the trachea, extubation from the trachea, and other procedures to be performed in front of the patient P. In particular, since the first and second hook-and-loop fasteners 22a, 22b have a certain degree of strength, mountain folds and maintenance of the folded state can be stably achieved. In addition, by forming a tent-shaped space inside the bag, the patient's sense of oppression can be minimized, and the bag can be expanded to make the internal space 20 easier to see from the outside. Furthermore, by adjusting the amount of adhesion between the first hook-and-loop fastener 22a and the second hook-and-loop fastener 22b, and between the second double-sided tape 24b, it is possible to appropriately set the opening size and position of the opening 18 according to the body type of the patient P, the surgical position, etc.

Furthermore, in this embodiment, the bag-shaped main body 12 is provided with a glove-shaped portion 48 that extends into the internal space 20, and the arm insertion opening (arm insertion opening 50) in the glove-shaped portion 48 is provided with a ring body 52 that is harder than the bag-shaped main body 12. This prevents the arm insertion opening 50 from collapsing during use and maintains it as a circular hole, making it easy to insert the arm. Also, in this embodiment, the glove-shaped portion 48 is formed separately from the bag-shaped main body 12 and attached to the ring body 52, so that the bag-shaped main body 12 and the glove-shaped portion 48 can be easily formed, and the design freedom of the bag-shaped main body 12 and the glove-shaped portion 48 can be improved.

In particular, in this embodiment, an elastic ring-shaped member 54 is provided at the opening end of the glove-shaped portion 48, and the opening end of the glove-shaped portion 48 is made an elastic opening end. This allows the glove-shaped portion 48 to be easily attached by hooking it onto the ring body 52.

Furthermore, in this embodiment, the bottom sides of the upper sheet-like portion 14 and the lower sheet-like portion 16 are provided with planned dangling portions 63a, 63b that hang down when in use, and these planned dangling portions 63a, 63b form a pocket-like portion 63 that opens up inside the bag-like main body 12 by utilizing the bottom portion of the bag-like main body 12. Therefore, the pocket-like portion 63 can store tools and the like necessary for treatment in advance, and tools and the like can be taken out of the pocket-like portion 63 as needed during treatment and used, or tools that have been removed or are no longer needed can be stored without interfering with treatment work.

In addition, in this embodiment, the center of the body axis of the head H of the patient P is located in the internal space 20 of the treatment bag-like body 10, biased to one side (right side) from the center in the left-right direction, and the service space 60 is provided on the other side (left side) from the center in the left-right direction. By providing such a service space 60, treatments such as intubation and extubation of the trachea of the patient P can be performed while suppressing interference with the treatment bag-like body 10.

Furthermore, the bag-shaped main body 12 of this embodiment is provided with a tube insertion portion 34 (tracheal insertion portion 34a, suction insertion portions 34b, 34c) through which the ventilator tube 56 and suction tube 64 are inserted, and a reinforcing member 42 is provided on the outer periphery of the circular hole 36 in the tube insertion portion 34. This allows the shape of the circular hole 36 to be stably maintained even when the ventilator tube 56 and suction tube 64 are inserted, making it easy to insert the ventilator tube 56 and suction tube 64 into the tube insertion portion 34.

A fragile portion 40 is provided in the tube insertion portion 34, and a tube such as a ventilator tube 56 or a suction tube 64 can be inserted into the tube insertion portion 34 by breaking through the fragile portion 40. In particular, in this embodiment, the fragile portion 40 is perforated, and the fragile portion 40 can be brought into contact with the outer circumferential surface of the tube after the tube is inserted, and the release of bacteria and viruses through the tube insertion portion 34 can also be suppressed.

Alternatively, the inner diameter of the insertion hole 44 in the tube insertion portion 34 can be made smaller than the outer diameter of the tube (the ventilator tube 56 or the suction tube 64) to be inserted, and the tube can be pushed in while contacting the inner peripheral edge of the insertion hole 44, thereby ensuring the airtightness of the tube insertion portion 34. In particular, even in such a case, the separate sheet 38 and the reinforcing member 42 are fixed by thermal welding at multiple points on the outer periphery of the insertion hole 44, so that the insertion hole 44 can be effectively prevented from being pushed wide. In addition, when a cross-shaped perforation is adopted as the fragile portion 40, by welding four points on the perforation ends, it is possible to prevent the tear caused by the insertion from extending beyond the welded points when the tube is inserted. It is preferable that the inner diameter of the circular hole 36 in the tube insertion portion 34 is set to be larger than the outer diameter of the tube to be inserted. This prevents the upper sheet-like portion 14 from tearing due to the pulling or weight of the tube when the tube is inserted through the circular hole 36, widening the circular hole 36, and creating a large hole in the upper sheet-like portion 14.

In this embodiment, double-sided tape 24 (first to third double-sided tapes 24a to 24c) is provided at the opening 18 of the bag-shaped main body 12. Of the first to third double-sided tapes 24a to 24c, the second double-sided tape 24b is used to adhere at least a portion of the portion folded in a mountain-like shape in front of the patient P, while the remaining portions of the first and third double-sided tapes 24a, 24c and the second double-sided tape 24b can be attached to the portions of the opening 18 of the bag-shaped main body 12 that face each other in the vertical direction or to the surface of the patient P. This can prevent misalignment between the patient P and the bag-shaped main body 12 and can keep the gap between the patient P and the bag-shaped main body 12 small, preventing the spread of bacteria and viruses to the outside.

Although the embodiments of the present invention have been described above, the present invention should not be interpreted as being limited to the specific descriptions in these embodiments, and can be implemented in various forms with various changes, modifications, improvements, etc. based on the knowledge of those skilled in the art.

In the above embodiment, a situation is assumed where a treatment device is installed on the right side of the patient (left side in FIG. 1), and the head H of the patient P is positioned biased to the right side of the treatment bag 10 in FIG. 1, and a service space 60 is provided on the left side of FIG. 1 to ensure space for handling piping connected to the device, but the service space 60 may be provided on the opposite side depending on the installation location of the device, the condition of the patient, the type of treatment, etc. That is, the head H of the patient P may be positioned biased to the left side of the treatment bag in FIG. 1, and a service space may be provided on the right side of FIG. 1. In this case, it is preferable that the part to be folded in a mountain shape is provided on the left side of FIG. 1 in the opening part of the bag-shaped main body, and the cut extending from the opening part toward the bag bottom is provided on the right side of FIG. 1 in the lower sheet-shaped part. However, the cut extending from the opening part toward the bag bottom is not essential in the present invention, and multiple cuts may be provided at different positions in the circumferential direction of the opening part.

In the above embodiment, the tube insertion portion 34 has a three-layer structure consisting of the upper sheet-like portion 14, the reinforcing member 42, and the separate sheet 38, and the perforated weak portion 40 is provided on the separate sheet 38, but the present invention is not limited to this embodiment. For example, FIG. 11 shows a tube insertion portion 70 in another embodiment of the present invention. In the embodiment shown in FIG. 11, a cross-shaped perforated weak portion 40 is formed on the tube insertion portion 70 of the upper sheet-like portion 14, and a ring-shaped reinforcing member 72 is attached to the outer periphery of the weak portion 40. That is, the reinforcing member 72 has an insertion hole 74 in the center, and the perforated weak portion 40 is formed on the inner periphery of the insertion hole 74. In this embodiment, the reinforcing member 72 is fixed to the inner surface side of the upper sheet-like portion 14, and in short, the tube insertion portion 70 consisting of the upper sheet-like portion 14 is overlapped so as to cover the insertion hole 74.

The method of attaching the reinforcing member 72 to the inner surface of the upper sheet-like portion 14 is not limited, and may be, for example, adhesive bonding or heat welding, but in this embodiment, the reinforcing member 72 is attached to the inner surface of the upper sheet-like portion 14 by a substantially rectangular double-sided tape 76. In addition, the position where the double-sided tape 76 is provided in the reinforcing member 72 is not limited, but when a cross-shaped perforated fragile portion 40 is used as in this embodiment, for example, the double-sided tape 76 is preferably provided at the four ends of the cross perforation as shown by the two-dot chain line in FIG. 11. This can prevent the tear caused by the insertion from extending beyond the fixed position when the tube is inserted into the tube insertion portion 70. However, the shape of the double-sided tape 76 is not limited to a rectangular shape, and may be a ring shape corresponding to the reinforcing member 72. In addition, it is preferable that the length of the perforations be set within a range of, for example, approximately half to approximately the same length as the inner diameter of the reinforcing member 72 (the diameter of the insertion hole 74).

12(a) and (b) show the state in which the tube (suction tube 64) is inserted into the tube insertion portion 70. That is, as shown in FIG. 12(a), a rubber band 78 may be inserted in advance around the suction tube 64, and as shown in FIG. 12(b), after the suction tube 64 is inserted into the tube insertion portion 70, the rubber band 78 may be moved toward the tip side in the insertion direction of the suction tube 64 to overcome the reinforcing member 72. As a result, the elasticity of the rubber band 78 that has overcome the reinforcing member 72 is applied to the upper sheet-like portion 14, and the upper sheet-like portion 14 is annularly tightened by the rubber band 78 against the outer circumferential surface of the suction tube 64 inserted inward from the tube insertion portion 70, thereby reducing the gap between the suction tube 64 and the upper sheet-like portion 14. This can prevent bacteria and viruses in the internal space 20 of the bag-shaped main body 12 from diffusing into the external space through the tube insertion portion 70. Such rubber bands 78 can be stored in advance, for example, in the storage space 55 formed in the treatment bag 10. The gap between the tube insertion portion and the tube to be inserted can be reduced by, for example, applying tape that sealed the tube insertion portion before use across the outer circumferential surface of the tube and the tube insertion portion after the tube is inserted. This can further prevent bacteria and viruses in the internal space 20 of the bag body 12 from spreading to the outside. The configuration of reducing the gap between the tube insertion portion and the tube to be inserted using rubber bands or tape can also be used in the first embodiment.

Therefore, as in the embodiment shown in Figs. 11 and 12, the fragile portion may be provided on the upper sheet-like portion, and the tube insertion portion may have a two-layer structure consisting of the upper sheet-like portion and the reinforcing member. That is, the reinforcing member may be provided on the outer periphery of the fragile portion provided on the upper sheet-like portion, in other words, the fragile portion provided on the upper sheet-like portion may be located within the insertion hole of the reinforcing member. The reinforcing member may be provided on the outer surface side of the upper sheet-like portion, or on the inner surface side as in the embodiment shown in Figs. 11 and 12. In addition, the tube insertion portion may be configured by fixing a rubber valve having a slit to the upper sheet-like portion, and the artificial respirator tube or tracheal tube may be inserted by pushing open the slit in the rubber valve.

Furthermore, in the above embodiment, the hook-and-loop fasteners 22 (first and second hook-and-loop fasteners 22a, 22b) and the double-sided tape 24 (first to third double-sided tape 24a to 24c) were provided partially around the circumference of the opening 18 of the bag-shaped main body 12, but these hook-and-loop fasteners and double-sided tape may be formed around the entire circumference of the opening. Also, in the above embodiment, the first to third double-sided tapes 24a to 24c were provided at approximately equal positions in the front-to-rear direction of the bag-shaped main body 12, but for example, the first double-sided tape may be provided further back than the second and third double-sided tapes. This makes it easier to align the tape when, for example, attaching the first double-sided tape to the back of the patient's neck and attaching the third double-sided tape to the back of the patient's shoulder.

Furthermore, in the above embodiment, the glove-like portion 48 was formed separately from the bag-like body 12 and attached to the ring body 52, but the glove-like portion may be fixed to the bag-like body by double-sided tape, welding, adhesion, etc., or may be formed integrally, and the ring body provided at the arm opening is not essential in the present invention.

The bag-shaped main body 12 may be partially transparent as long as the area required for treatment is visible from the outside. For example, the lower sheet-like portion 16 may be opaque, or may be colored to make treatment tools easier to see. It is also possible to set a specific color only to specific locations, such as the area where the head should be placed or the edge of the opening, which makes it easier to identify specific areas and facilitates work compared to when the entire body is transparent.

Furthermore, the edge of the opening 18 of the bag-shaped main body 12 may be partially protruding in the circumferential direction to be longer in the opening direction or shorter toward the bottom side. For example, the length that is inserted into the patient's back can be shortened to reduce the amount that the patient's upper body is lifted, and the length on the patient's chest side can be made longer to cover the chest area in a drape-like manner, improving the sealing performance.

Furthermore, depending on the method of treatment or procedure and the patient's condition, it is possible to insert and install a rigid frame member inside the bag-shaped body, thereby reliably and stably securing an appropriate amount of space in the required location inside the bag-shaped body and providing stable support for pipes, etc.
