Description

  The present invention relates to a surgical pouch for storing a liquid discharged from an operation part, and in particular, in an operation such as ophthalmology, otolaryngology, brain surgery, orthopedic surgery, etc. The present invention relates to a surgical pouch suitable for use and a method of using the same.

  At the time of surgery, a disinfectant solution, a surgical irrigation solution, or the like is used at or around the surgical site to disinfect and clean the surgical field. These fluids are often not properly eliminated and can leak onto the human body and clothing, causing discomfort to the patient, such as during local anesthesia, and sometimes even hindering the performance of the surgery. Therefore, how to treat this drainage is a problem.

  Conventionally, in such an operation, a covering cloth (drape) opened by the operation part is adhered to the skin to cover the periphery of the operation part, and the liquid discharged from the operation part is allowed to flow down on the surface of the drape. is doing. In addition, a method of attaching a liquid collection bag to the outside of the drape and receiving the drainage is widely used, and various proposals have been made for improving such a liquid collection type drape (the following patents). Reference 1).

  Also, in surgery such as ophthalmology, a method of bringing an absorbent device formed of a highly absorbable material into contact with the drainage fluid and absorbing and holding it is widely performed. Various proposals have been made regarding shapes and the like (Patent Document 2 below). Furthermore, since such an absorber has a problem that absorption cannot catch up when a large amount of drainage from the surgical site occurs, a surgical fluid absorber suitable for processing a large amount of fluid has also been proposed. (Patent Document 3 below).

  Usually, it is necessary to sufficiently disinfect a relatively wide area around the surgical site using a large amount of disinfectant prior to surgery. In general, in this disinfection stage, the disinfecting solution flows down through the skin without using a drape, and therefore, the disinfecting solution receiving container is often pressed against the skin below the surgical section to allow the disinfecting solution to flow into the container. However, a gap is often generated between the container and the skin, and it is inevitable that the periphery of the surgical part is wet with the disinfectant. Wiping this wet part with gauze or the like must be avoided as much as possible because it may be contaminated again.

  The area around the surgical site is covered with a drape after disinfection. Usually, an adhesive tape attached to the inner surface of the periphery of the opening of the drape is attached to the skin. However, when the skin is wet as described above, the adhesive tape does not stick well, or peels off in the middle, often resulting in a gap between the drape and the skin. For this reason, body fluids such as irrigation and blood flow down on the skin surface during surgery, resulting in contamination of the human body and clothes, which is a problem that cannot be overlooked in terms of hygiene.

  Therefore, the present invention is a surgical pouch for storing liquid discharged from the surgical section, and can be placed between the drape and the skin so that the surgical drainage can be received without leakage, and the operation does not wet the skin even during disinfection. It is an object to provide a pouch for use and its usage.

  The surgical pouch of the present invention for solving the above-mentioned problems is provided with an impervious bag main body for storing surgical drainage flowing down from the surgical section, and a predetermined width only on the back side over substantially the entire width of the mouth of the bag main body. An overhang portion extending above the height, formed on the outer surface of the overhang portion, formed on the outer surface of the front surface near the mouth of the bag body, a first adhesive surface that adheres to the human skin under the surgical section, A second adhesive surface to be adhered to the covering cloth, and a water-impermeable sheet wider than the mouth of the bag body, a third adhesive surface is formed on one upper side of the sheet, and a release surface on the lower side of the adhesive surface The third adhesive surface of the protective tape is detachably adhered to the inner surface of the overhanging portion and the release surface is adhered to the second adhesive surface before storing the surgical drainage. To seal the mouth of the bag body and remove the protective tape when storing the surgical drainage. And it is characterized in that it is configured to open the bag body and.

  According to such a configuration, it is possible to prevent the disinfecting liquid from leaking out during the disinfection before the operation or the surgical drainage fluid from leaking out during the operation to contaminate the human body and clothes. That is, at the time of disinfection, if the bag body sealed with the protective tape is adhered to the skin under the operation part and the disinfecting liquid is transmitted along the surface of the bag main body and flows into the disinfecting liquid receiver, the disinfecting liquid There is no risk that the human body or clothes get wet. At the time of surgery, the upper end of the back of the bag body is in close contact with the skin by the first adhesive surface, and the upper end of the front surface is in close contact with the covering by the second adhesive surface. All (irrigation, blood, etc.) flow into the bag. Further, since an adhesive surface for adhering to the skin is usually formed on the inner surface around the opening of the covering cloth, there is almost no room for surgical drainage to flow into the gap between the skin and the covering cloth. In addition, the first adhesive surface of the pouch is adhered to the skin before the skin gets wet with the disinfectant, and the second adhesive surface is completely covered with the protective tape, so there is no concern about the adhesive surface of the pouch becoming poorly bonded. Absent.

The surgical pouch has an arc shape in which the mouth of the bag body, the upper end of the overhanging portion, and the upper end of the protective tape are curved downward, and at least before the surgical drainage is accommodated, the bag body has a wide upper portion. It is preferable to have a wide planar shape.
With this configuration, it can be easily used in a rounded part such as a face or a head. In particular, in ophthalmic surgery or the like, such an arc shape is desirable for attaching the pouch to the skin on the side of the eye operated in a supine state. Moreover, when sticking on the side surface of a face, the one where the width | variety below the bag is narrow has a good fit, and there exists an advantage that there exists a sense of stability.

In the above-mentioned pouch, the bag body is formed in a wide planar shape that expands symmetrically downward, and before the surgical drainage is accommodated, the enlarged parts on both sides of the bag body are folds that are inclined vertically or inwardly. The folded portion may be restored by the liquid weight when the surgical drainage is accommodated, and the inner volume of the bag may be increased. In addition, a bottom surface portion having a uniform width is formed at the lower end of the bag body, and a side surface portion having a width expanding downward is formed on both side surfaces. The inner portion of the bag may be configured to be restored by the weight of the liquid when the surgical drainage is accommodated.
With such a configuration, until a considerably large amount of surgical drainage is accommodated in the bag, the lower portion of the bag can be maintained in a narrow shape, and the inner volume of the bag can be increased as necessary.

  In any of the above-mentioned pouches, the lower part of the bag body is provided with a discharge port and a discharge channel for surgical drainage in the bag, and has an opening and closing means for opening and closing the discharge port or the discharge channel. There may be. With such a configuration, when the amount of surgical drainage is large, a drainage receptacle can be arranged below the pouch, and the surgical drainage can flow into the drainage receptacle via the pouch.

Furthermore, it is preferable that any of the above-mentioned pouches is provided with a mouth opening means for increasing the opening area of the bag body when the protective tape is peeled off.
Such a mouth-opening means is a one-step or a plurality of steps of vertical hook-like folds provided on both side surfaces in the vicinity of the mouth of the bag body, and in the state where the protective tape is adhered, the folding means May be configured such that when the protective tape is peeled off without any gap, the opening of the bag body is enlarged by the restoring force of the sheet constituting the folded portion.

Furthermore, the above-mentioned mouth opening means

And a slit with a width W that is symmetrically cut out on both sides of the long piece at a predetermined position of the guide hole of the fixed piece.
In the vicinity of the free end of the movable piece, a protruding protrusion having a width projecting on both sides of the long piece is larger than the W, a gap portion having a width larger than the w and smaller than the W, and then the free end side on both sides. The fixed end side is slanted gently, and a serrated check claw whose tip width is slightly larger than W is formed close to each other, and before opening the bag, the free end of the movable piece When the side of the movable piece is positioned in parallel with the gap between the fixed piece and the back of the bag body to maintain the sealed state of the bag, and the front side of the bag body is pulled forward, the free end side of the movable piece is It slides in the slit direction along the guide hole, the check claw of the movable piece comes out from the slit to the front side of the bag body, the gap portion is constrained to the position of the slit, and one end is Gap on the inner front side of the bag body and the gap at the other end By the elastic restoring force of the movable Dohen constrained by the slit, or may be configured to maintain the 拡口 state of the bag.

  Furthermore, in addition to the above-mentioned widening means comprising a combination of a fixed piece and a movable piece, this widening means has one or more vertical hook-like folds on both side surfaces near the mouth of the bag body. It is provided that the restoring force of the sheet that is provided and constitutes the folding portion is configured to assist the opening of the bag by the elastic restoring force of the movable piece.

According to the present invention, the pouch is positioned between the skin and the covering cloth, and the surgical drainage discharged from the surgical site can be received in the pouch without leakage, and the skin and clothes are not wetted even during disinfection, The disinfectant solution can be stored in the disinfectant receiver.
As a result, it has become possible to completely prevent surgical drainage and disinfectant from leaking onto the human body and clothing, causing discomfort to the patient and hindering the performance of surgery. .

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings of the examples. FIG. 1 is a perspective view of a surgical pouch according to a first embodiment of the present invention, and this pouch is composed of a bag body 1 and a protective tape 5. 1 (a) shows the bag body, FIG. 1 (b) shows the protective tape alone, and FIG. 1 (c) shows the state in which the mouth of the bag body is sealed with the protective tape.

  As can be seen in the figure, the back side of the bag body 1 is extended upward by a predetermined height over substantially the entire width of the bag mouth to form an overhang portion 2. A first adhesive surface 3 is formed on the outer surface (outside of the back surface) of the overhang portion 2, and the first adhesive surface 3 is intended to adhere to the human skin surface below the surgical portion when the surgical pouch is used. To do. In addition, a second adhesive surface 4 is formed on the front outer surface in the vicinity of the mouth of the bag body 1 over substantially the entire width of the mouth. The second adhesive surface 4 is used to prevent the gap between the pouch and the covering cloth by adhering to the inner surface of the covering cloth when covering the periphery of the surgical part with a covering cloth (drape) during the operation. It is.

  The pouch is provided with a strip-shaped protective tape 5 longer than the width of the mouth of the bag body 1. The protective tape 5 has a third adhesive surface 6 (upper part of the broken line in the figure) 6 formed on one side (the back surface in FIG. 1B), and a release surface below the adhesive surface ( 7 is formed. Before the surgical drainage is stored in the pouch, the protective tape 5 is releasably bonded to the release surface formed on the inner surface of the overhang portion 2 and the release surface 7 is attached to the third adhesive surface 6. It is for sealing the opening | mouth of a bag main body by making it adhere to said 2nd adhesion surface. Then, by peeling off the protective tape 5 from the bag main body, the bag is opened and the surgical drainage can be accommodated therein.

  The bag main body 1 and the protective tape 5 of such a surgical pouch need to be formed of an impermeable sheet that can be deformed to some extent. For example, a waterproof paper sheet or a soft resin sheet such as polyethylene or polypropylene can be suitably used. The pressure-sensitive adhesive surface may be formed by a method conventionally used for adhesive tapes and the like, and the mold release surface may be formed by a conventional method such as a method of applying an appropriate release agent.

  Since the appropriate size and shape of the bag body 1 differ depending on the target surgery, various shapes and sizes may be used depending on the purpose. The protective tape 5 has only to be a size that can seal the mouth of the bag, and usually a strip-shaped tape is used, but it is not necessarily limited to this. The size and shape of the overhanging portion 2 are usually about the same as the folded portion of the envelope, but it suffices if the protective tape 5 is bonded to the inner surface of the overhanging portion 2 so that the bag mouth can be sealed.

  FIG. 2 is a plan view of a surgical pouch according to a second embodiment of the present invention. FIG. 2 (a) shows a bag body and FIG. 2 (b) shows a protective tape. In this example, the mouth of the bag body 1, the upper end of the overhang portion 2, and the protective tape 5 are formed in an arc shape curved downward. Moreover, the width | variety of the upper part of the bag main body 1 is wide, and the downward direction is narrowed, and the bag main body is formed in the wide planar shape. These configurations are intended to facilitate use in rounded parts such as the face and head. The first adhesive surface 3 and the second adhesive surface 4 are formed following the curvature of the arc of the bag mouth. Correspondingly, the third adhesive surface 6 and the release surface 7 also follow the shape of the bag mouth. Is formed.

  Particularly in ophthalmic surgery and the like, such an arc shape is desirable for attaching the pouch to the skin on the side of the eye operated in a supine state. Moreover, when it sticks on the side of the face, it is because the one where the width | variety below the bag is narrow has a sense of stability. The appropriate radius of curvature of the arc and the wide inclination angle differ depending on the body part to be used, and may be appropriately selected according to the purpose. Note that at least the upper end of the protective tape 5 has an arc shape, and the third adhesive surface 6 and the release surface 7 may be formed corresponding to the shape of the bag body. Further, the configuration in which the opening of the bag main body or the like is formed in an arc shape and the configuration in which the bag main body is formed in a wide planar shape are not necessarily adopted at the same time, and only one of them may be used.

  FIG. 3 is a plan view of a surgical pouch according to a third embodiment of the present invention, and is a schematic view of a bag body in a state where no protective tape is applied. In this example, the configuration of the bag main body is the same as that of the second embodiment, except that it has a drainage for surgical drainage. That is, a discharge port 8 and a discharge channel 9 are provided in the lower part of the bag body 1, and an opening / closing means 10 is arranged in the discharge channel 9.

  For example, the discharge port 8 may be formed by reinforcing a sheet around the hole to provide an opening, and the discharge flow path 9 may be made of a soft resin pipe, for example. The opening / closing means 10 may be a method of tightening the discharge flow path 9 from the outside with, for example, a pinch cock. Since the surgical pouch of the present invention is disposable after a single use, it is desirable that it can be manufactured as inexpensively as possible. In addition, the surgical drainage liquid in a bag may be continuously discharged | emitted to the drainage receiving container arrange | positioned under the pouch during a surgery, and may be discharged | emitted collectively after completion | finish of a surgery.

  FIG. 4 is a plan view of a surgical pouch according to a fourth embodiment of the present invention. This pouch is characterized in that it is used by folding the lower part of the bag. FIG. 4 (a) shows the unfolded state and FIG. 4 (b) shows the folded state. As seen in FIG. 4 (a), the bag body 1 is formed in a wide planar shape that expands symmetrically downward. Before the surgical drainage is accommodated, the enlarged portions on both sides below the bag body are folded and used along the fold line 11 inclined inward.

That is, as seen in FIG. 4B, a folded portion 12 that is folded back on the front side is formed so that the lower width is narrowed. At the time of surgical drainage accommodation, the folded portion 12 is reconstructed by the liquid weight so that the inner volume of the bag is increased. By configuring in this way, until a considerable amount of surgical drainage is contained inside the bag,
The shape which the lower part of the bag narrowed can be maintained, and the internal volume of a bag can be enlarged as needed. As will be described later, the pouch of the present invention is also used for the purpose of preliminarily sticking to the skin at the time of disinfection before surgery and flowing down the disinfectant solution through the surface. In that case, the effect that the folding | turning part 12 functions as a wall which prevents the side leakage of disinfecting liquid is also acquired.

  FIG. 5 is a perspective view of a surgical pouch according to a fifth embodiment of the present invention. This pouch is characterized in that the lower part of the bag is folded inward, and FIG. 5 (a) shows a state where the lower part is enlarged, and FIG. 5 (b) shows a state where the part is folded. As shown in FIG. 5 (a), a bottom surface portion 13 having a constant width is formed at the lower end of the bag body 1, and a side surface portion 14 having a width expanding downward is formed on both side surfaces. Before the surgical drainage is accommodated, as seen in FIG. 5 (b), the bottom surface and the side surface are folded inward along the central fold line 11 so that the volume of the bag is small.

  At the time of surgical drainage accommodation, the folded portion is reconstructed by the liquid weight so that the inner volume of the bag is increased. By comprising in this way, until the considerable amount of surgical drainage is accommodated in the inside of a bag, the shape which the lower part of the bag narrowed can be maintained and the internal volume of a bag can be enlarged as needed Is the same as the pouch of the third embodiment. In both the third and fourth embodiments, the upper end of the bag body has an arcuate shape curved downward, but it may be a straight line. Further, in the fourth embodiment, the width of the bag body is constant up and down, but it may be a wide shape.

  FIG. 6 is an explanatory diagram of a method of using the pouch of the present invention, and shows an ophthalmic surgery as an example. FIG. 5A shows a state at the time of disinfection before surgery, and FIG. 5B shows a state at the time of surgery. The first adhesive surface (the back surface of the overhang portion) of the pouch bag body 1 is adhered to the skin surface below the operation portion. At this time, the mouth of the bag is sealed with the protective tape 5. In this state, the surgical part is disinfected with the disinfecting liquid, and the discharged disinfecting liquid is caused to flow down the surface of the bag body 1 sealed with the protective tape 5 and flows into the disinfecting liquid receiver 15 placed therebelow. .

  Next, after removing the disinfectant adhering to the surface of the bag body 1 or the protective tape 5 as necessary, the protective tape 5 is peeled off to open the mouth of the bag, and as shown in FIG. The face is covered with a covering cloth 16 having an opening around the part. At that time, the inner surface of the covering cloth 16 (near the edge of the opening) is adhered to the second adhesive surface formed at the upper front end of the bag body 1. If the surgery is performed in this state, the surgical drainage flowing down from the surgical section can be accommodated in the bag body 1.

  As described above, when the pouch of the present invention is used, there is almost no fear that the disinfectant or the surgical drainage leaks out and contaminates the human body or clothes. First, at the time of disinfection, if a bag body 1 or a protective tape 5 having a sufficiently wide width is used, the disinfectant liquid hardly leaks to the left and right of the pouch. If necessary, a bag body with folded portions formed on the left and right sides as shown in FIG. 4 may be used, or folded portions may be provided on the left and right ends of the protective tape to prevent the side leakage of the disinfectant.

  At the time of surgery, the upper end of the back of the bag body is in close contact with the skin and the upper end of the front surface is in close contact with the covering cloth. If the bag mouth is wide enough, surgical drainage (irrigation, blood, etc.) All flows into the bag. In addition, since an adhesive surface for adhering to the skin is usually formed on the inner surface around the opening of the covering cloth, there is almost no room for surgical drainage to flow into the skin and the covering cloth.

  In the conventional use of the covering cloth, the covering cloth is adhered to the surface of the skin that has become wet during disinfection, so adhesion failure often occurs.However, in the pouch of the present invention, the second adhesive surface is not removed during disinfection. Because it is completely covered with protective tape, there is no worry of poor adhesion. Further, in the conventional use of the covering cloth, the bag for receiving the surgical drainage is disposed outside the covering cloth. However, in the pouch of the present invention, the bag is disposed between the skin surface and the covering cloth and is being disinfected. Since the bag is kept in close contact with the skin throughout the operation, it can be said that there is no concern that the surgical drainage will contaminate the human body and clothes.

  It should be noted that when using the pouch of the present invention as described above, the opening of the bag body must be sufficiently opened when the protective tape is peeled off before the start of surgery. . If the opening of the bag body is not sufficient, the surgical drainage fluid does not flow into the pouch well, resulting in soiling of the covering cloth and the floor surface below it, which is also a sanitary problem. Therefore, it is preferable that the pouch of the present invention is provided with a mouth opening means for increasing the opening area of the bag body when the protective tape is peeled off. Various methods are conceivable as the mouth opening means, and a few preferred mouth opening means will be described below.

FIG. 7 is a perspective view of a surgical pouch according to a sixth embodiment of the present invention. This pouch is provided with hook-like folds on both side surfaces near the mouth of the bag body to facilitate opening when the protective tape is peeled off. FIG. 7A shows a state where the protective tape is peeled off and the mouth is expanded, and FIG. 7B shows a state where the mouth is sealed with the protective tape. As shown to Fig.7 (a), the folding part 17 extended in the vertical direction and folded inward was provided in the both sides | surfaces vicinity of the opening | mouth of the bag main body 1. As shown in FIG. In this embodiment, the folding is performed in three stages, but the number of folding stages may be more or less than this.

  As shown in FIG. 7 (b), in the state where the protective tape 5 is adhered, the folding portion 17 is folded without any gap while being constrained by this. There is no hindrance. Since the bag mouth is also sealed, there is no fear of the disinfectant flowing in. If the protective tape is peeled off, the opening of the bag body naturally expands due to the restoring force of the sheet constituting the folding portion 17. If the material of the sheet constituting the side surface of the bag is appropriately selected, folding and opening by restoring force can be made compatible.

FIG. 8 is a perspective view of a surgical pouch according to a seventh embodiment of the present invention. This pouch expands by the elastic restoring force of a slidable belt-like sheet (movable piece) arranged near the mouth of the bag, and the mouth expanding means is a combination of the movable piece and a fixed piece for fixing the movable piece. It has become.
FIG. 8A is a perspective view showing how the movable piece and the fixed piece are attached, FIG. 8B is a plan view of the fixed piece, and FIG. 8C is a plan view of the movable piece.
As shown in FIG. 8A, the fixed piece 18 is attached in a horizontally long manner on the inner side of the back surface of the bag body 1 and below the overhang portion 2. The movable piece 19 is attached to the inside of the bag body 1 in the vicinity of the front opening in a horizontally long manner.

  As shown in FIG. 8B, the fixed piece 18 has a rectangular guide hole 20 having a width w formed therein, and a predetermined position of the long piece of the guide hole 20 (approximately in the vicinity of the center of the width of the bag body). Are provided with slits 21 having a width W that are symmetrically cut out on both sides. Further, the fixed piece 18 is made of a waterproof sheet, and is adhered to the back inner side of the bag body 1 except for the periphery of the guide hole 20. In the present embodiment, the hatched portions at both end portions of the fixed piece 18 are the bonding portions 22.

  As shown in FIG. 8C, the movable piece 19 is made of a belt-like sheet having a width slightly smaller than the width w, and is made of an elastic material having a certain degree of deformation resistance. One end thereof is bonded to the inside of the front surface of the bag body 1 at a position corresponding to the guide hole 20. The hatched portion in the figure is the bonding portion 22 bonded to the inside of the front surface of the bag body 1 (this end portion is referred to as a fixed end). The opposite end is not bonded to the bag body and can freely slide in the lateral direction along the guide hole 20 (this end is referred to as a free end).

  In the vicinity of the free end of the movable piece 19, a retaining protrusion 23, then a gap portion 24, and then a check claw 25 are formed close to each other. The retaining protrusion 23 is for preventing the movable piece 19 from slipping out of the slit 21, and is a protrusion protruding on both sides at the free end and having a width larger than the width W of the slit 21. The width of the gap portion 24 is larger than the width w of the guide hole 20 and smaller than the width W. When this portion enters the slit 21, it is restrained by the slit 21 and cannot move in the lateral direction. It has a function. The check pawl 25 is formed in a sawtooth shape with the free end side standing upright on both sides and the fixed end side being gently inclined, and the width of the tip thereof is slightly larger than W. The check pawl 25 is slightly deformed and can be pulled out of the slit 21 due to the flexibility of the sheet constituting the movable piece 19, but once it is pulled out, it cannot be returned in the reverse direction by the upright surface.

  FIG. 9 is a perspective view for explaining the operation of the mouth-opening means of this embodiment. FIG. 9 (a) shows a state before opening, FIG. 9 (b) shows a state after opening, and FIG. FIG. 10C is an enlarged view of a portion A in FIG. Before opening the bag, as shown in FIG. 9 (a), the free end side of the movable piece 19 is located in the gap between the fixed piece 18 and the back of the bag body 1 in parallel therewith. In the state, there is no problem in making the bag mouth sealed by a protective tape (not shown).

  When opening the bag, the protective tape is first peeled off, and the front surface of the bag body 1 is pulled forward. Thereby, the free end side of the movable piece 19 slides in the direction of the slit 21 along the guide hole 20. When the check claw 25 of the movable piece 19 reaches the position of the slit 21, it comes out from the slit 21 to the front side of the bag. 9C, the movement in the direction perpendicular to the guide hole 20 is restricted by the retaining protrusion 23 and the check claw 25. As shown in FIG. Further, the movement in the direction horizontal to the guide hole 20 is limited to the position of the slit 21 because the width of the gap 24 is larger than w. Therefore, the gap portion 24 is constrained to the position of the slit 21. In this state, the movable piece 19 has a fixed end bonded to the inside of the front surface of the bag body, and the gap portion 24 at the free end is restrained by the slit 21, so that the movable piece 19 is bent and elastically restored. Since the force works, the expanded state of the bag is maintained.

  If the mouth widening means as in the seventh embodiment is used, it is possible to reliably maintain the mouth widened state with a simple operation. Moreover, since an inexpensive material can be used and it can be manufactured simply by bonding to the inner surface of the bag, the manufacturing cost is also low. In addition, in order to ensure the opening more, or in order to enlarge the opening area of a bag, you may apply combining the structure of the above-mentioned Example 6 and the structure of the said Example 7. FIG. In other words, the movable piece and the fixed piece may be attached to the inner surface of the bag body, and a hook-like fold may be provided on both side surfaces near the mouth of the bag body to facilitate the opening when the protective tape is peeled off.
