Description

Specification

Stoma receiving bag fitting

Technical field

The present invention relates to an attachment device for attaching a waste storage bag (receiving bag) to an opening of a colostomy.

Background art

[0002] The colostomy is an artificial excretion opening in which a hole is made in the abdominal wall of a person who has had the rectum or the like removed by surgery, and the distal end of the cut intestine is exposed, and is also called a "stoma".

[0003] Since the stoma does not have a sphincter and the defecation time cannot be adjusted, it is necessary to receive and process the stool that is always excreted in a receiving bag called a “pouch” or the like.

[0004] For this purpose, a receiving bag such as a bouch must be attached to the stoma opening portion of the abdominal wall. Conventionally, a mounting member for attaching and detaching the receiving bag is attached with an adhesive or double-sided tape. Attaching to the skin around the ma is done (hereinafter referred to as the “adhesion method”).

[0005] However, because the application method repeatedly places a burden on a specific part of the skin, it is impossible to attach the bouch itself if there are many cases where the skin is shaken or painful due to inflammation. There was a problem.

[0006] Therefore, as can be seen in the following patent documents, various mounting tools for mounting a receiving bag such as a bouch without using an adhesive or the like have been developed.

Patent Document 1: Japanese Patent Publication No. 6-98164

Patent Document 2: Japanese Patent Laid-Open No. 10-305057

Patent Document 3: Japanese Patent Application Laid-Open No. 60-100960

Patent Document 4: JP-A 63-181759

Patent Document 5: Japanese Patent Laid-Open No. 04-180754

Patent Document 6: Japanese Unexamined Patent Publication No. 2003-144475

Patent Document 7: Japanese Utility Model Publication No. 02-131421

[0007] An example seen in Patent Document 1 ("Conventional Example 1") is a device body called a perforated disk plate having a diameter of about 50 mm and made of a hard material and having an opening for stoma in the center, and a flexible rubber plate. A pack (a stool bag) that is a plastic bag and a flat belt that attaches the plate to the body, and the opening of the pack is covered with a protruding part with a height of about 20 mm standing on the plate surface. A colostomy prosthesis designed to be attached.

[0008] Another example ("conventional example 2") found in Patent Document 2 is a waste-containing bag, a body-side flange connected to the waste-containing bag via a force ring, and a body-side member pressed against the body. A stoma prosthesis comprising a mounting member that is fixed to the body, wherein the body-side member includes a skin-contact member having a through-hole through which the stoma can be passed, and a plurality of protrusions projecting from the surface of the skin-contact member. The mounting member includes a pressing ring that can be secured to the outer periphery of the protruding portion, and a belt that is attached to the pressing ring and wound around the body. In addition, a pad having a through hole may be sandwiched between the body side member and the body. In this case, the pad is disposed on the oil applied to the skin on the outer periphery of the stoma.

[0009] In each of the above examples, since the member for attaching the bouch is tied to the body with a belt or the like, the problem of skin irritation caused by the adhesive is temporarily solved.

[0010] However, in Conventional Example 1, the area surrounding the colostomy, which has a small outer diameter of about 50 mm, is small, but it is 20 mm thick. When I move my body in sports, I'm worried about the plate being misaligned. In addition, the rubber pack is too soft to be disposable, which is difficult to clean. When replacing a rubber pack in the toilet, it seems unstable to work with one belt removed.

[0011] Further, in Conventional Example 2, a configuration in which the pressing ring is held at a predetermined position on the skin member by a plurality of convex portions protruding from the surface of the skin member is employed, but this configuration functions satisfactorily. However, there was a problem that the convex part was deformed and the pressing ring was displaced.

[0012] As described above, the examples of conventionally-developed bouch attachment devices are both unsatisfactory because they are both merits and demerits from the viewpoint of usability and have problems as described later.

[0013] It should be noted that the above-mentioned mounting tool has a predetermined shape and dimensions and is mounted with a dedicated receiving bag called a bouch or a pack to which a coupling member is attached. There is a demand that general soft plastic bags, such as supermarket shopping bags, which are unspecified for shape 'dimension' applications, can also be used as receiving bags. Dedicated voucher etc. However, it is somewhat expensive, and it is expected that it will be difficult to obtain at the time of a disaster, etc., so it is preferable to select from materials as close as possible.

Disclosure of the invention

Problems to be solved by the invention

[0014] A bouch wearing device that can be attached to the body with a belt or the like is easy to shift due to the movement of the body and is tightened with a large force, so it is strong and lacks flexibility. The first of the problems of the present invention is to provide a mounting tool that is flexible and does not need to be tightened with a large force with good adhesion.

Another object of the present invention is to make it possible to use, as a receiving bag, a general soft plastic bag such as a supermarket shopping bag that can be used only by a dedicated bouch.

[0016] If the member for wearing the bouch is tied to the body, it may bite into the skin and cause pain. In addition, a part of the mounting member may be damaged by direct contact with an easily damaged stoma. A further problem of the present invention is to not damage a stoma that is less painful.

[0017] A problem common to conventional vouch attachments is that the bouch attachment / detachment portion includes unnecessary irregularities, and it is difficult to clean and clean the dirt that has entered the portion. Another object of the present invention is to enable easy cleaning and cleaning of dirt.

Means for solving the problem

[0018] Means for solving the above problems are provided by the following stoma receiving bag mounting tool. That is,

Flange 1 (see Fig. 1 (A)), which is a perforated disc with a predetermined thickness, is made of a soft rubber or elastomer with moderate soft strength and has an opening 6 for stoma in the center. Short Cylinder-shaped coupling member 2 for mounting the bouch 8 (see Fig. 1 (B), Fig. 2), with its base part being held together and fixed at a position surrounding the stoma opening on the upper surface of the flange And a circular press ring 3 made of stainless steel (see Fig. 3 and Fig. 4) on the flange top surface, in the middle position between the flange end and the coupling member, pressing the flange evenly against the stoma site on the body surface ), And a belt 4 (see Fig. 3 and Fig. 4) that is connected to the pressure ring and is attached to the body so as to apply a pressing force by pulling it to the left or right or three directions, and a stoma opening on the flange. Around A pressing ring holding portion made of a hard resin short circular tube with a groove 51 for gripping the pressing ring at the top. The pressing ring belt is applied to the groove. The outer groove wall is lacking at the contact point, and the inner wall of the groove is moved toward the inside of the cylinder by the thickness of the belt, and the base of the protrusion is embedded and fixed integrally with the flange at a predetermined position on the upper surface of the flange. A stoma receiving device equipped with a pressing ring holding portion 5 (see FIGS. 1 (B) and 1 (C)).

The above-mentioned “moderate softness” refers to a range where the value of “JIS hardness A by A-type durometer” is approximately 10 to 30. It is desirable for the flange to be in close contact with the skin surface, and it is preferable that this level of softness is not soft enough. . An example of such a soft rubber is silicone rubber.

[0020] In the receiving bag mounting device of the present invention, in order to protect a stoma that is easily damaged, the inner periphery of the base of the coupling member is disposed outside the inner periphery of the center opening of the flange, and the flange The corner of the wall surface of the central opening of the is rounded.

[0021] In the receiving bag mounting tool of the present invention, the side surface of the ridge constituting the pressing ring holding portion, the surface of the flange connected thereto, and the coupling so as to facilitate the cleaning and cleaning of dirt. The inner wall of the member and the surface force S of the flange surrounded by the member are both finished to a smoothly continuous concave surface.

[0022] In the receiving bag wearing device of the present invention, the outer edge portion is thinned over a predetermined width to be softened so that the end of the flange does not bite into the skin and cause pain. The leading edge is rounded.

[0023] In the receiving bag mounting tool of the present invention, as a belt, a connecting ring (9) provided separately from the pressing ring is provided so that a stable mounting state can be obtained without applying an excessive tightening force. A three-pronged belt in which three belts that pass through the waist and the crotch are stretched can be used. It should be noted that a belt of rubber or soft plastic having a width of about 30 to 35 mm is suitable for benoret itself because it is resistant to dirt.

[0024] In the receiving bag mounting tool of the present invention, the diameter of the flange can be about 100 to 120 mm, the thickness can be about 10 mm, and the diameter of the pressing ring can be about 70 to 90 mm. With such a dimensional structure, there is a sense of security against misalignment even when moving the body in sports, I don't mind the protrusion of clothes when wearing it.

[0025] In forming the receiving bag mounting tool of the present invention, a coupling member and a pressing ring holding portion formed separately from a flange from a hard resin (for example, PP or PET) are previously molded into a rubber mold. The flange can be formed by placing it at a predetermined position and supplying a soft rubber or elastomer material thereto. This is called the insertion molding method, and the coupling member and the pressing ring holding portion made of different materials can be firmly fixed to the upper surface of the flange.

The invention's effect

According to the invention of claim 1 of the present application, the large pressing ring 3 is held by the sturdy pressing ring holding part 5, and the base of the pressing ring holding part is embedded in the flange 1. Since it acts as a hard core, the flange 1 retains its shape and gives the rigidity required to be uniformly pressed against the stoma site. Therefore, the pressing state of the flange against the body surface is stable, the state of close contact with the skin is appropriate, there is no anxiety about slippage during sports, and excessive belt tightening force is required.

[0027] Further, in addition to being able to attach a dedicated bouch 8 to the coupling member 2 provided in advance, the coupling member 2 can be diverted, or a general plastic bag such as a supermarket shopping bag can be used by the pressing ring holding portion 5 and the pressing ring 3. A typical soft plastic bag 10 can also be used as a receiving bag. This is useful when the stock of dedicated vouches is exhausted or when it is difficult to obtain.

[0028] In that case, the pressing ring 3 is tightly held in the groove 51 even at the location where the pressing ring holding portion 5 makes a round without a break around the stoma opening 6 and the belt 4 of the pressing ring 3 contacts. There is no possibility that the contents will leak from the soft plastic bag sandwiched between the pressing ring 3 and the groove 51.

[0029] According to the invention of claim 2, the base portion of the coupling member 2 made of hard resin does not exist inside the inner periphery of the center opening 6 of the flange 1 made of soft rubber or elastomer, In addition, since the corner of the wall surface of the center opening of the flange is rounded, the tip of the easily damaged scratcher is protected from direct damage to the base of the hard coupling member.

[0030] According to the invention of claim 3 of the present application, the side surface of the ridge constituting the pressing ring holding portion 5 and The surface of the flanges and the inner wall of the coupling member 2 and the surface of the flange surrounded by the same member are all finished in a smooth concave surface, so that the attached dirt can be easily wiped off with tissue paper, etc. You can leave and easily wash and flush.

[0031] According to the invention of claim 4, the outer edge of the flange is thinned and softened over a predetermined width, and the tip is rounded, so that one end of the flange is surrounded by the body posture. Even when it touches the skin, the outer edge will bend flexibly, and it will not bite into the skin and cause pain.

According to the invention of claim 5 of the present application, since the flange 1 as a member for mounting the bouch and the pressing ring 3 that presses the flange 1 against the body surface are supported by being pulled and supported from three directions by the three-pronged belt 4. It is not necessary to apply an excessive pulling force that is more stable than the support by pulling in two directions.
