JP5489036B2 - Suction liquid storage bag for aspirator - Google Patents

Description

  The present invention relates to an aspirating liquid storage bag for an aspirator that is attached to an aspirator used in medical treatment or on-site and accommodates in order to process a liquid such as a body fluid sucked by the aspirator.

  In general, aspirators for aspirating body fluids such as sputum, nasal discharge and blood are widely used in medical practice. In this suction device, a suction pipe leading to a suction nozzle and a decompression pipe leading to a decompressor are communicated with a top cover of a plastic or glass suction liquid reservoir, and the inside of the suction liquid reservoir is communicated by the decompressor. By reducing the pressure, the body fluid is sucked from the suction nozzle, the sucked body fluid is discharged into the suction liquid storage container and accumulated at the bottom, and the air is discharged from the pressure reducing pipe (for example, Patent Document 1).

  Further, in this type of conventional suction device, a liquid such as a sucked body fluid is put in a disposal bag mounted in a suction liquid storage container, and a water-absorbing material is stored in the bag and absorbed therein. The technology that makes it possible is known. (For example, patent document 2).

  However, as shown in Patent Document 1 described above, in the method in which the sucked body fluid or the like is directly stored in the suction liquid storage container, the suction liquid storage container itself is discarded when the sucked body fluid or the like is discarded. If there is a risk of infection with viruses or pathogens in body fluids, there is a problem that medical accidents are likely to occur due to carelessness at the time of treatment, and there is a problem that a lot of work is required for cleaning.

  On the other hand, as shown in Patent Document 2, a bag for disposal is stored in a suction liquid storage container, a suction liquid is stored therein, and the bag is discarded as described above. In addition, it is possible to save the labor of carrying out the cleaning work every time the suction liquid storage container is used, but it takes time to attach and detach the bag, and the bag contains water-absorbing material. Since the opening remains open at the time of disposal, there is a problem that a medical accident is likely to occur at the time of disposal if it is used without containing the water-absorbing material. Also, since the inside of the waste bag is depressurized to suck the liquid, if it is used in a state where a large amount of air remains between the suction liquid storage container and the bag, the air is decompressed. There was a problem that the amount of storage allowed in the bag was reduced.

  In view of the above problems, the present invention can easily discard the suction liquid at a low cost, prevent a medical accident, and maximize the volume of the disposal bag for storing the suction liquid. It was made for the purpose of providing an aspirating liquid storage bag for an aspirator that can be used for the above.

The feature of the invention described in claim 1 for solving the conventional problems as described above is an upward-opening type suction liquid storage container, and a lid that is fitted to an opening of the suction liquid storage container and closes the same. And a lid for connecting a liquid suction pipe to the lid, and a connector for connecting a pressure reduction pipe leading to the pressure reducer. In a suction liquid storage bag for an aspirator that is mounted freely and stores suction liquid sucked from the liquid suction pipe, the lower end side of the barrel portion formed into a cylindrical shape by a flexible synthetic resin film is closed and the upper end side is opened. A bag main body having a holding piece portion sandwiched between the suction liquid storage container and the lid body at the opening of the bag main body, the bag main body being below the holding piece portion The inner peripheral surface has a zipper with a sealed structure, The bag main body is provided with a ventilation portion that communicates the inside and outside of the bag main body between the fastener and the holding piece, and the ventilation portion opens and closes the front and back through-hole portions by forming a cut in the bag main body. The tongue piece is provided integrally .

The feature of the invention described in claim 2 is that, in addition to the configuration of claim 1, the outer peripheral surface of the bag body is a rough surface provided with a number of fine irregularities .

The suction liquid storage bag for an aspirator according to the present invention has a bag body in which a lower end side of a barrel portion formed into a cylindrical shape by a flexible synthetic resin film is closed and an upper end side is opened as described in claim 1. A holding piece portion sandwiched between the suction liquid storage container and the lid, and integrally sealed to the inner peripheral surface of the bag body below the holding piece portion. By installing the structural fastener, it can be easily installed in the suction liquid storage container simply by sandwiching the holding piece when the lid is fitted to the opening of the suction liquid storage container. When taking out from the liquid storage container, the inside of the bag body is sealed by closing the fastener, so that the liquid inside does not leak when taking out from the suction liquid storage container, and it is possible to prevent medical accidents from occurring. .

  In addition, the present invention includes a ventilation portion that communicates the inside and outside of the bag body at a portion between the fastener and the holding piece portion of the bag body so that the holding piece is sandwiched between the suction liquid storage container and the lid body. The ventilation part is in the suction liquid storage container in the mounted state, and when the pressure in the suction liquid storage container is reduced, the air remaining between the bag body and the suction liquid storage container is also reduced in pressure. Since this does not expand due to the reduced pressure in the suction liquid storage container, the volume in the container body does not decrease and can be used efficiently.

  Further, the ventilation portion is integrally provided with a front and back through-hole portion and a tongue piece-like portion that opens and closes by forming a cut in the bag body, so that the ventilation portion is normally substantially closed by the upper portion of the tongue piece. Even if the liquid that has been sucked in is scattered, the large amount of leakage from the vent is prevented.

The present invention, on the outer peripheral surface of the bag body as set forth in claim 2, by previously subjected to rough surface processing in which a large number of fine irregularities, the air between the suction liquid storage container and the bag body When the pressure is reduced, the air left between the suction liquid storage container and the bag body is depressurized through the fine gap, and the air partially stays and expands. Disappears.

  Next, an embodiment of the suction liquid storage bag for an aspirator according to the present invention will be described based on the examples shown in the drawings.

  1 and 2 show an embodiment of a suction liquid storage bag for an aspirator according to the present invention. In the figures, reference numeral 1 denotes a bag body. The bag body 1 is formed of a flexible synthetic resin film such as polyethylene, the lower end of the cylindrical body portion 2 is closed by the bottom sheet portion 3, and the upper end side is an opening that can be opened and closed. . In the opening, a pair of holding pieces 4 and 4 are integrally formed in an extended arrangement.

  On the underside of the opening, a rail-type fastener 10 having a sealed structure is integrally formed on an inner peripheral surface at a position separating a space for forming a ventilation portion.

  In the ventilation portion forming space, a plurality of ventilation portions 7 are formed by integrally forming a front and back through hole portion and a tongue piece portion 6 for opening and closing the same by forming a V-shaped cut 5 in the bag body 1. ing. In addition, this cut | interruption 5 can be made into various shapes, such as U shape, U shape, and a semicircle shape other than V shape.

  The bottom sheet portion 3 constitutes a waiting portion whose center is folded upward. Moreover, the seal | sticker parts 8 and 8 are formed in the both edges of the bag main body 1, and it forms in the cylinder shape closed with the bottom sheet | seat which comprises a waiting part in the bottom part.

  Moreover, the outer peripheral surface of the bag body 1 is a rough surface including a large number of fine irregularities (not shown) including the outer surface of the bottom sheet portion 3. This rough surface can be formed, for example, by applying a texture to one surface during film formation.

  The rail fastener 10 has a structure in which the opening resistance from the inside of the opening is larger than the opening resistance to the opening force from the outside of the opening.

   More specifically, as shown in FIG. 1 and FIG. 2, the half-circumferential portions of the overlapping film constituting the opening portion of the body portion 2 are set as the base portions 11 and 12 (shown in FIG. 3). In addition, a chuck portion 13 for opening and closing between the both base portions is provided.

  As shown in FIG. 3, the chuck portion 13 is a male sealing rail portion 14 integrally projecting on the surface of one base portion 11 and a male portion projecting integrally with the other base portion 12. The sealing rail part 15 is sealed by being inserted.

  The female sealing rail portion 14 is provided with a pair of female rod rail portions 17a and 17b that protrude from the base portion 11 and have hook-shaped claw portions 16 having a hook-like cross section on the inner side surface of the distal end portion. The male sealing rail portion 15 protrudes integrally on the surface of the other base portion 12, and has a claw-shaped claw portions 18 and 18 having a hook-like cross section on the outer surface of the tip portion, and between the female heel rail portions 17a and 17b. A pair of male rails 19, 19 are provided.

  In addition, a sealing rail portion 20 that is press-fitted between both male rod rail portions 19 and 19 of the other base portion 12 is integrally projected at an intermediate position between both female rod rail portions 17a and 17b of one base portion 11. By inserting the male sealing rail portion 15 into the female sealing rail portion 14, the claws 16 and 18 between them are combined with each other and the sealing rail portion 20 is connected to the male rod. The rail portions 19 and 19 are press-fitted between the back surfaces 19a and 19a.

  The sealing rail portion 20 includes a head portion 20a having a shape in which both sides are bulged at a tip portion thereof, and both side surfaces of the head portion 20a press the back surfaces 19a and 19a of the male male rail portions 19 and 19 respectively. They are in line contact with each other, and the gas-liquid tightness is maintained.

  Further, the cross-sectional shape of the base portion of one female heel rail portion 17a of the female sealing rail portion 14 is formed into a taper shape that becomes thicker toward the base portion 11 side, and thereby the female heel rail portion 17a. Therefore, the bending force applied to the base portion 11 on which the protrusion is protruded is easily transmitted to the female heel rail portion 17a. Therefore, as shown in FIG. 5, the female heel rail portion 17a is easily formed by bending the base portion 11 outward. Are formed in an easily open side engaging portion that can be easily detached from the claws 16 and 18 that are bent in a direction away from the male rail portion 19 and engaged with each other.

  On the other hand, the base portion of the other pistil rail portion 17b has a shape curved toward the one pistil rail portion 17a in the same manner as the inner side surface as its outer surface reaches the base portion 11. The root portion has an arcuate portion 21 whose thickness a (shown in FIG. 3) is formed to be thicker than the thickness b of the base portion 11, and whose cross-sectional shape is formed in an arc shape. For this reason, when a bending force in the opening direction acts on the base part 11, as shown in FIG. 4, the base part 11 bends at the position outside the root part of the pistil rail part 17b, and the bending force is the pistil rail. It forms a difficult-to-open engagement portion that is not easily transmitted to the portion 17b but does not easily disengage between the claw portions 16 and 18 that are engaged with each other.

  In this embodiment, when forming the synthetic resin film, the rail portions constituting the rail fastener 10 are integrally formed toward the length direction of the synthetic resin film, and the seal portions 8 and 8 are fused and formed by folding them. Although the bag body 1 with rail fasteners is formed by cutting the center, the rail fasteners may be formed individually and fused to a film.

  Furthermore, in the embodiment described above, a rail fastener having a structure in which the opening resistance from the inside of the opening is larger than that from the outside is used, but a normal hermetic rail fastener may be used.

  Next, a usage example of the above-described suction liquid storage bag for an aspirator will be described.

  FIG. 5 shows a suction device equipped with the suction liquid storage bag A for the suction device according to the present invention. In FIG. 5, 30 is an upward opening type suction liquid storage container constituting the suction device, and 31 is a suction liquid. It is a lid that is fitted into the opening of the storage container 30 to close it. A cylindrical connector 32 for connecting the liquid suction pipe and a cylindrical connector 33 for connecting the decompression pipe leading to the decompressor are integrally formed on the lid 31, and each penetrates the lid 31. The suction hole 32a and the suction hole 33a are opened.

  A suction pipe 35 having a liquid suction nozzle 34 connected to the tip thereof is connected to the connector 32, and a pressure reducing pipe 37 leading to the pressure reducing tank 36 is connected to the connector 33. The inside of the decompression tank 36 is decompressed by a decompression pump 38.

  When the bag A is mounted in the suction liquid storage container 30, as shown in FIG. 5, the holding pieces 4 and 4 on the bag body opening edge are wound around the suction liquid storage container 30 opening edge. In this state, the lid 31 is fitted and the holding piece portions 4 and 4 are sandwiched and held.

  At this time, the body portion and the bottom portion of the bag body 1 are expanded along the inner surface of the suction liquid storage container 30, and the ventilation portion 7 is located in the suction liquid storage container 30.

  With the bag A attached and covered as described above, the inside of the suction liquid storage container 30 is depressurized, and liquid such as a bag is sucked from the suction nozzle 34. The sucked liquid is stored in the bottom of the bag A by its own weight in the suction liquid storage container 30, and the air is discharged from the decompression pipe 37.

  When the inside of the suction liquid storage container 30 is depressurized, the air between the bag A and the inner surface of the suction liquid storage container 30 is also depressurized through the vent portion 7, but the outer peripheral surface of the bag A is a rough surface. The entire area is uniformly decompressed through the gap formed by the rough surface, and the bag A is maintained in the expanded state when worn without shrinking.

  When discarding the liquid stored in the bag A in this way, the lid body 31 is removed, the holding pieces 4 and 4 are stacked, and the rail fastener 10 is opened from the opening of the suction liquid storage container 30. Lift up to the top of the bag, close the rail fastener 10 and seal the inside of the bag body 1. In this state, the bag A is taken out and discarded. Thereby, the liquid accommodated in the bag can be disposed of without leaking outside.

  In addition, since fasteners that are difficult to open depending on the pressure inside the bag are used, they cannot be easily opened even if there is a fall accident during transportation.
