TECHNICAL FIELD OF THE INVENTION
The present invention relates to a pouch for storing excrement excreted from a stoma formed on a body surface.
[0002]
[Prior art]
A person who has removed the bladder due to a disease such as the bladder forms a stoma on the surface of the body in order to excrete urine and the like out of the body. A pouch is attached for storing and temporarily storing the excrement excreted from the stoma. To attach this pouch to the body, a one-piece type that attaches the pouch directly to the body, and a two-piece type that uses a pouch with a face plate to be attached to the body and a detachable part that can be detachably attached to this face plate In any case, the excrement is stored in the pouch.
[0003]
However, since the size of the pouch is limited in order to be attached to the body, there is a certain limit in the capacity for storing excrement, and it is necessary to replace the pouch itself or to transfer the excrement out of the pouch occasionally. Was. Therefore, the pouch is provided with an outlet at the bottom so that the excrement is transferred to the outside of the pouch, a transfer tube is attached to the outlet, and the excrement in the pouch is taken out of the pouch.
It is difficult to change the pouch due to sleep, especially at night, etc., and since the excrement is stored in the pouch for a long time, there is a possibility that the capacity of the pouch may be exceeded, and the excrement is transferred to a separately provided tank. As described above, the user sleeps with the transfer tube attached to the outlet. At this time, the tank is often placed under the bed, and the tip of the tube has been introduced into the tank provided under the bed for storing excrement.
[0004]
Then, since the excrement always flows through the tube and into the tank due to the head drop between the pouch and the tank, the inside of the pouch has a negative pressure. Therefore, since the pouch is formed by bonding a top sheet and a back sheet made of a synthetic resin, the top sheet and the back sheet sometimes come into close contact with each other. In addition, when two backflow prevention sheets are provided in the pouch, the two backflow prevention sheets sometimes come into close contact with each other. In particular, when excrement residue is present on the surface of the front sheet and the back sheet or on the surface of the two backflow prevention sheets, the adhesion is likely to occur.
In such a case, if the excrement is discharged from the stoma, the excretion is stored only in the upper portion of the pouch or near the opening, and the excretion may not flow to the lower portion of the pouch. In such a case, there was a danger that the person who attached the pouch would suffer significantly.
[0005]
[Problems to be solved by the invention]

[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a rear view of the pouch of the present invention, FIG. 2 is a partial longitudinal sectional view taken along line AA of FIG. 1, and FIGS. 3, 4, and 5 are respectively BB of FIG. It is a cross-sectional view along a line, a CC line, and a DD line.
As shown in FIG. 1, the pouch 1 has a semicircular shape at the top, a straight line at the bottom, and a slightly flared shape at both sides. The shape of the pouch 1 may have a funnel shape at the lower portion in order to store excrement, and is appropriately selected depending on the use state, the intended use, and the like.
The configuration of the main body of the pouch 1 includes a top sheet 2 and a back sheet 3. The peripheral edges of the top sheet 2 and the back sheet 3 are bonded to form a bag, and can store excrement. When the top sheet 2 and the back sheet 3 are cut out of one sheet, since they are continuous at the bottom, only the top and both sides are bonded.
[0012]
The material of the top sheet 2 and the back sheet 3 needs to have properties such as water resistance, impact resistance not torn by pulling and the like, and tensile strength so that no excrement leaks, and the state of excrement can be observed. Since transparency is also required, a film of high-pressure polyethylene, ethylene-vinyl acetate copolymer, vinyl chloride, or the like is used.
An opening 8 is attached to the upper part of the back sheet 3, and the opening 8 receives excrement from a stoma formed on the surface of the body. The portion of the back sheet 3 corresponding to the opening 8 is cut out, and the cut edge of the back sheet 3 is bonded or welded to the opening 8. The opening 8 is provided with a fitting portion 81, and the fitting portion 81 is fitted with a mounting member directly adhered to the body, and is sealed so that excrement does not leak. The opening 8 is provided with a grip 82 that is gripped when the pouch 1 is removed from the mounting member.
When the pouch 1 is directly attached to the body, an adhesive layer may be provided on the opening 8 and directly attached to the body around the stoma.
[0013]
As shown in FIG. 2, a skin protection sheet 4 is provided on a portion of the back sheet 3 that contacts the body outside. The skin protection sheet 4 has a portion corresponding to the opening 8 cut out, and the cut edge of the skin protection sheet 4 is adhered or welded to the opening 8. As shown in FIG. 1, the skin protection sheet 4 is provided up to the vicinity of the bottom of the back sheet 3 to prevent the body and the back sheet 3 from coming into contact with each other.
As the skin protection sheet 4, a non-woven fabric with good air permeability, a mesh type sheet, or the like is used. Since this sheet has good air permeability, even if the pouch 1 is in direct contact with the body, it does not stick and does not cause any discomfort.
[0014]
As shown in FIGS. 2, 3, and 4, a first backflow prevention sheet 5 and a second backflow prevention sheet 6 are provided in the pouch 1 for backflow prevention. The first backflow prevention sheet 5 is provided on the top sheet 2 side, and the second backflow prevention sheet 6 is provided on the back sheet 3 side. The first backflow prevention sheet 5 and the second backflow prevention sheet 6 have a size substantially equal to the upper half of the pouch 1, and the periphery thereof is bonded together with the top sheet 2 and the back sheet 3 except for the lower side. The portion corresponding to the opening 8 of the second backflow prevention sheet 6 is cut out, and the cut edge of the second backflow prevention sheet 6 is bonded or welded to the opening 8. Therefore, the excrement that has entered through the opening 8 enters between the first backflow prevention sheet 5 and the second backflow prevention sheet 6, and is pouched from the lower side between the first backflow prevention sheet 5 and the second backflow prevention sheet 6. Fall down within one.
[0015]
As shown in FIG. 3, the first backflow prevention sheet 5, the second backflow prevention sheet 6, the back sheet 3, and the skin protection sheet are located slightly above the lower sides of the first backflow prevention sheet 5 and the second backflow prevention sheet 6. Numerals 4 are welded to each other at a welding portion 10 in a spot shape. In this embodiment, four welding points 10 are provided at substantially equal intervals, but the number can be changed as appropriate according to the size of the pouch 1 or the like.
For this reason, even if the excrement stored below the pouch 1 jumps upward due to vibration or the like, it does not enter upward from between the first backflow prevention sheet 5 and the second backflow prevention sheet 6.
[0016]
A discharge section 9 is provided at the bottom of the pouch 1 for transferring excrement to the outside of the pouch 1. The discharge unit 9 includes a pipe-shaped discharge port 91 and a stopper 92. By attaching a transfer tube to the discharge port 91, the excrement in the pouch 1 can be transferred to a tank or the like provided outside. When the transfer tube is not attached, a stopper 92 is fitted into the outlet 91 to prevent excretion from leaking.
[0017]
Between the first backflow prevention sheet 5 and the second backflow prevention sheet 6 in the pouch 1, a hollow or solid discharge tube 7 extends from slightly below the opening 8 to the lower part of the pouch 1 or the discharge port 91 of the discharge part 9. Is provided. The upper end of the discharge tube 7 is preferably about 5 mm below the lower end of the opening. In the case of the hollow discharge tube 7, the excrement entered through the opening 8 smoothly flows into the discharge tube 7, and in the case of the solid discharge tube 7, the discharge tube 7 and the first reverse flow This is because excrement smoothly flows into the gap between the prevention sheet 5 and the second backflow prevention sheet 6. If the distal end of the discharge tube 7 is too far away from the opening and located below, there is a possibility that the first backflow prevention sheet 5 and the second backflow prevention sheet 6 are adhered to make it difficult for excrement to flow into the discharge tube 7. This is because if the tip of the discharge tube 7 is too close to the opening, it may come into contact with the stoma or the skin.
[0018]
When the lower end of the discharge tube 7 is provided to the lower part of the pouch 1 or the discharge port 91 of the discharge part 9, even if the top sheet 2 and the back sheet 3 are stuck, excrement can be poured to the bottom of the pouch 1. it can. When provided to the lower portion of the pouch 1, the top sheet 2 and the back sheet 3 have few portions to be stuck, and the top sheet 2 and the back sheet 3 are easily separated from each other, so that the discharged material can be stored. The lower part of the pouch 1 is below the lower sides of the first backflow prevention sheet 5 and the second backflow prevention sheet 6 and below the middle between the lower end of the opening 8 and the bottom of the pouch 1. When the discharge tube 91 is provided, the excrement can be directly poured into the transfer tube when the transfer tube is attached to the discharge port 91.
[0019]
Since the discharge tube 7 is provided between the first backflow prevention sheet 5 and the second backflow prevention sheet 6, even if the first backflow prevention sheet 5 and the second backflow prevention sheet 6 are adhered to each other, the discharge tube 7 is smoothly discharged. To the bottom of the pouch 1.
The discharge tube 7 is fixed to the second backflow prevention sheet 6 and the back sheet 3. Therefore, the discharge tube 7 does not move in the pouch 1 due to the movement of the body. In addition, as described above, in this embodiment, the first backflow prevention sheet 5 and the second backflow prevention sheet 6 are spot-welded to the back sheet 3 and the four welding portions 10. By passing the discharge tube 7 between the welding portions 10, even if the discharge tube 7 and the second backflow prevention sheet 6 are released from being fixed, the discharge tube 7 does not swing significantly.
[0020]
In the pouch 1 in which the first backflow prevention sheet 5 and the second backflow prevention sheet 6 are not provided, the discharge tube 7 is fixed to the back sheet 3 in the pouch 1. As described above, the discharge tube 7 is provided from a position slightly below the opening 8 to the lower part of the pouch 1 or the discharge port 91 of the discharge unit 9. The upper end of the discharge tube 7 is preferably about 5 mm below the lower end of the opening.
Even when the first backflow prevention sheet 5 and the second backflow prevention sheet 6 are not provided, the discharge tube 7 allows the excrement to be smoothly pouched even when the top sheet 2 and the back sheet 3 are stuck. To the bottom.
[0021]
The discharge tube 7 may be a pipe-shaped hollow type or a flexible rod-shaped solid type.
For the discharge tube 7, a soft material is used so as to follow the movement of the body. For example, a tube made of a soft synthetic resin such as silicon rubber or polyvinyl chloride can be used, and the outer diameter is 2.5 mm. From about 3.5 mm can be used. If the outer diameter is 2 mm or more, the hollow discharge tube 7 is hardly clogged with excrement. In the case of clogging or in the case of a solid discharge tube 7, the outer surface has a circular cross section, so that a gap is generated between the top sheet 2 and the back sheet 3 or between the first backflow prevention sheet 5 and the second backflow prevention sheet 6. The excrement can flow down the pouch 1 from this gap.
When the excrement that has flowed down reaches the bottom of the pouch 1 through the discharge tube 7, the space between the top sheet 2 and the back sheet 3 of the pouch 1 can be spread, and the excrement can be stored in the entire pouch 1. it can.
[0022]
【The invention's effect】
According to the present invention, since the discharge tube is provided in the pouch, even if a sheet of the pouch is stuck, the excrement can be smoothly guided from the vicinity of the opening to the lower side of the pouch 1, so that the excrement is reliably stored. The pouch can be ejected, and the pouch can be left safely installed for a long time.
