Description

Technical Field

[0001] This application relates to a medical device, and more particularly to a colostomy defecation device. Background Technology

[0002] For patients with colostomies, a colostomy baseplate is installed at the stoma, and then a colostomy bag is attached to the baseplate to collect feces discharged from the intestines through the stoma. Because the stoma does not have a sphincter like the anus, feces can be discharged into the colostomy bag at any time; the colostomy bag hangs outside the patient's body, causing inconvenience. Current colostomy bags are made of plastic, which traps gas discharged from the intestines, unlike anal gas which can escape into the air; when gas enters the colostomy bag, it bulges, causing further inconvenience. Furthermore, the end of the intestine connected to the stoma may shrink over time. Summary of the Invention

[0003] In view of the above problems, this application aims to provide a colostomy defecation device that can prevent feces from being discharged from the intestines at any time and allows for selection of defecation time as needed; this application also aims to provide a colostomy defecation device that can prevent feces from being discharged when gas is expelled from the intestines; this application also aims to provide a colostomy defecation device that can help prevent the end of the intestine connected to the stoma from narrowing.

[0004] The colostomy and defecation device of this application includes: a base and a bag body component;

[0005] The base includes a cylindrical first neck and a fixing ring; the fixing ring is integrally connected to a first end of the first neck and extends outward from the first neck; the fixing ring is used to fix the subject's body surface by surrounding the colostomy opening of the subject's colon; external threads are formed on the outer peripheral surface of the first neck;

[0006] The bag body component includes: a first annular connecting ring and a bag body; the inner circumferential surface of the first connecting ring has an internal thread, and the first connecting ring is used to connect to the first neck; the bag body is made of waterproof and breathable fabric, the first end of the bag body is open, and the second end of the bag body is closed; the outer circumference of the first end of the bag body is fixed around the second end of the first connecting ring; the bag body is folded or wrapped into a column shape for partial insertion into the end of the colon to provide support for the end of the colon.

[0007] Preferably, the bag body component further includes a bag body fixing cover; the bag body fixing cover includes a second coupling ring and an insert tube;

[0008] The second coupling ring is used to fit around the outer periphery of the first coupling ring; the insert is used to insert into the folded or wrapped bag body to provide a support center for the folding or wrapping of the bag body; the second end of the second coupling ring is fixed together with the second end of the insert.

[0013] Preferably, a through hole is formed in the middle of the vent cover, and the through hole is covered with a medical silicone film.

[0014] The colostomy and defecation device of this application has a bag body for containing feces. When the subject does not want to defecate, it is not hung outside the subject's body, but is folded or wrapped into a cylindrical shape and inserted into the base and the end of the subject's colon. After the bag body is folded or wrapped, it is difficult for feces to enter the bag body, and the cylindrical bag body inserted into the end of the colon provides support and prevents closure. The bag body is made of breathable material, so that gas in the colon can pass through the bag body and be discharged. The design of the exhaust cap allows the subject to observe the bulging of the medical silicone membrane on it to determine that gas needs to be discharged, and then remove the exhaust cap to allow the gas to be discharged from the body.

[0027] The colostomy and defecation device of this application will now be described in detail with reference to the accompanying drawings.

[0028] The colostomy and defecation device of this application includes: a base 1 and a bag body component 2.

[0029] The base 1 includes a cylindrical first neck 1b and a fixing ring 1a; the fixing ring 1a is integrally connected to the first end of the first neck 1b and extends outward from the first neck 1b; the fixing ring 1a is used to fix the subject's body surface around the colostomy opening of the subject, for example by adhesive bonding or suturing. If suturing is used, suture holes need to be pre-set on the fixing ring 1a. External threads are formed on the outer peripheral surface of the first neck 1b. The main function of the base 1 is to install the bag body component 2.

[0030] The bag body component 2 includes: a first annular connecting ring 2a and a bag body 2b; the inner circumferential surface of the first connecting ring 2a is formed with an internal thread, and the first connecting ring 2a is used to connect to the first neck 1b, thereby installing the bag body component 2 onto the bag base 1.

[0031] The bag body 2b is made of waterproof and breathable fabric, such as waterproof fabric used in umbrellas. The inner and outer sides of the fabric can be coated, for example, with a Teflon coating, which can both waterproof the bag and reduce the adhesion of feces. The first end of the bag body 2b is open, and the second end is closed. The outer periphery of the first end of the bag body 2b is fixed around the second end of the first connecting ring 2a. The bag body 2b is folded or wound into a column shape for partial insertion into the end of the colon, providing support to the end of the colon.

[0032] The bag body component also includes a bag body fixing cover; the bag body fixing cover includes a second connecting ring 2c and an insertion tube 2d.

[0033] The second coupling ring 2c is used to fit around the outer periphery of the first coupling ring 2a, for example, by insertion or threaded connection; the insert tube 2d is used to insert into the folded or wrapped bag body 2b to provide a support center for the folding or wrapping of the bag body 2b; the second end of the second coupling ring 2c is fixed together with the second end of the insert tube 2d.

[0034] The first end of the insertion tube 2d is closed; multiple air holes are provided on the first end of the insertion tube 2d; the first end of the insertion tube 2d is covered by the bag body 2b, such as Figure 8 As shown, the bag body 2b is divided into multiple segments, with adjacent segments forming a nested structure, thereby folding the bag body 2b into a columnar shape; wherein the insertion tube 2d is closed by the second end of the bag body 2b.

[0035] The second end of the bag body 2b is fixedly connected to the first end of the insertion tube 2d by a connecting line 2e.

[0036] The second end of the cannula 2d extends outward to form a second neck; an exhaust cap 3 is installed on the second neck. The annular edge of the exhaust cap 3 is inserted into the second neck, and a through hole is formed in the middle of the exhaust cap 3. The through hole is covered with a medical silicone membrane 3b, which is used to indicate whether gas is stored in the intestine and needs to be released.

[0037] In the standby state, the bag components are folded, such as Figure 8As shown, the bag body is folded or wound into a cylindrical shape and inserted into the fixing ring of the base, with its front end inserted into the end of the colon to support the end and prevent the end of the colon from constricting. If there is gas in the intestine, the gas passes through the folded bag body, enters the cannula through the air hole, and accumulates in the cannula. If there is a lot of gas, more and more gas accumulates in the cannula, increasing the internal pressure and causing the medical silicone membrane to bulge. At this time, the subject can remove the air release cap to expel the gas from the cannula. At this time, because the folded cylindrical bag body and the cannula are still inserted in the base and the end of the colon, they obstruct the flow of feces in the colon, preventing the feces from being expelled along with the gas. When the subject wants to defecate, for example in the morning or evening, after removing the second connecting ring, the cannula is pulled out from the folded bag body. The cannula and the second end of the bag body are pulled out together, the bag body returns to its extended state, the obstruction in the colon is relieved, and the feces flow from the colon into the bag body. The subject then removed the first connecting ring from the neck of the base, thereby detaching the bag component from the base. After cleaning the base, another clean, folded bag component was inserted into the base.
