Description

Technical Field

[0001] The invention belongs to the field of ostomy bags, and in particular relates to a leak-proof ostomy bag for rectal cancer surgery. Background Art

[0002] After rectal cancer surgery, the patient's intestines need to be separated by stents and diaphragms, which causes intestinal blockage, making it impossible for fecal water to be discharged from the anus. Therefore, a shunt tube needs to be drawn out from the patient's abdomen to draw out the fecal water in the intestine. Among them, a stoma needs to be formed on the patient's abdomen for the shunt tube to extend. In order to ensure the hygiene of the stoma, the existing care methods all use gauze to cover the stoma, so that the fecal water flowing out of the stoma is absorbed by the gauze, so the gauze needs to be replaced regularly to prevent the gauze that absorbs fecal water from contacting the stoma for a long time and causing infection. In addition, the shunt tube needs to be connected to a drainage bag at one end outside the patient's body to collect the fecal water drawn out from the shunt tube in the drainage bag, and the drainage bag can be hung by the bed when resting in bed, and carried by hand when getting up and walking.

[0003] The above method has the following problems: 1. To ensure hygiene, the gauze needs to be replaced frequently, which makes replacement inconvenient. The problem often occurs in the middle of the night. Due to untimely replacement, the gauze absorbs too much fecal water and contacts the infected stoma. The fecal water is also easy to spread to other parts of the patient's skin and to the patient's clothes to cause contamination. 2. The drainage bag is often exposed outside the patient's clothes, making it easy to be observed by people around.

[0019] In order to enable those skilled in the art to better understand the present invention, and thus to more clearly define the scope of the present invention, the present invention is described in detail with respect to some specific embodiments of the present invention. It should be noted that the following are only some specific implementation methods of the present invention, which are only part of the embodiments of the present invention, wherein the specific and direct description of the relevant structure is only for the convenience of understanding the present invention, and each specific feature does not naturally and directly limit the scope of implementation of the present invention. The conventional selection and replacement made by those skilled in the art under the guidance of the present invention should be regarded as within the scope of the present invention.

[0020] like Figure 1-Figure 10 As shown, the present invention discloses a leak-proof ostomy bag after rectal cancer surgery, comprising: a bag body 1, a collecting cavity 11 is arranged in the bag body 1, the collecting cavity 11 is in a structure that is small at the top and large at the bottom, a collecting opening 12 is arranged on the upper rear side of the collecting cavity 11 for a drainage tube and fecal water flowing out of the stoma to enter the collecting cavity 11; an annular adhesive plate 2, the adhesive plate 2 is arranged at the collecting opening 12 so that the bag body 1 is attached to the abdomen through the adhesive plate 2, and a ring hole 21 smaller than the collecting opening 12 is arranged on the adhesive plate 2; a screw cap assembly 3, the screw cap assembly 3 is arranged at the bottom of the bag body 1 and is connected to the collecting cavity 11, the screw cap assembly 3 is opened to discharge the fecal water in the collecting cavity 11, and the screw cap assembly 3 is closed to seal the fecal water in the collecting cavity 11; the length of the bag body 1 is s1, wherein 20cm≤s1≤30cm.

[0021] Therefore, 1. After the rectal cancer surgery is completed, the shunt tube is inserted into the annular hole 21 and the collecting opening 12 to enter the collecting cavity 11, and the adhesive plate 2 is attached to the abdomen, and the stoma is located in the annular hole 21, so that the fecal water flowing out of the shunt tube or the fecal water flowing out directly from the stoma is directly collected in the collecting cavity 11, eliminating the traditional method of using gauze to cover the stoma, so that there is no need to frequently change the gauze, and only attention needs to be paid to the fecal water collection in the collecting cavity 11. In addition, after a certain amount of fecal water is collected, it is conveniently released by opening the screw cap assembly 3. 2. The collecting cavity 11 adopts a small upper and large lower structure, so that the length of the bag body 1 can be shortened while ensuring that the space in the collecting cavity 11 is sufficient, so that the ostomy bag can be covered by clothes when in use and is not easily observed by people around, and has better privacy.

[0022] Among them, the bag body 1 includes an upper bag 13 and a lower bag 14 located below the upper bag 13, the collecting opening 12 is arranged on the upper bag 13, the collecting chamber 11 includes an upper chamber 111 arranged in the upper bag 13 and a lower chamber 112 arranged in the lower bag 14, the upper bag 13 is provided with a non-return guide portion 134 extending into the lower chamber 112, the non-return guide portion 134 is used to be stretched open during the downward flow of feces in the upper chamber 111 so that the feces can be guided into the lower chamber 112, and when the feces in the lower chamber 112 surrounds the outer periphery of the non-return guide portion 134, the non-return guide portion 134 is squeezed and closed to prevent the feces from flowing back into the upper chamber 111.

[0023] Therefore, the fecal water directly flowing out of the stoma first enters the upper chamber 111, and then passes through the non-return guide part 134 to enter the lower chamber 112, and the diversion tube can be inserted into the lower chamber 112 through the upper chamber 111, so that the fecal water in the diversion tube directly flows into the lower chamber 112. When in use, the fecal water flowing out of the stoma is relatively small, while the fecal water flowing out of the diversion tube is relatively large, so that the main source of fecal water is directly introduced into the lower chamber 112 for collection to ensure effective collection, and the fecal water with a smaller flow rate flowing out of the stoma first passes through the upper chamber 111 and then enters the lower chamber 112 to ensure that fecal water will not accumulate in the upper chamber 111 and contact the stoma to cause infection, and in the event of an accident, such as the ostomy bag is turned upside down, the non-return guide tube prevents the fecal water in the lower chamber 112 from entering the upper chamber 111 to prevent the fecal water from contacting the stoma to cause infection.

[0024] Specifically, the upper bag 13 includes a first front layer 131 and a first rear layer 132, the outer peripheral shapes and sizes of the first front layer 131 and the first rear layer 132 are adapted to each other, and a first connecting edge 133 is arranged at the outer periphery of the first front layer 131 and the first rear layer 132; the lower bag 14 includes a second front layer 141 and a second rear layer 142, the outer peripheral shapes and sizes of the second front layer 141 and the second rear layer 142 are adapted to each other, and a second connecting edge 143 is arranged at the outer periphery of the second front layer 141 and the second rear layer 142; the non-return guide portion 134 includes a first section 1341 arranged at the lower part of the first front layer 131 and a second section 1342 arranged at the lower part of the first rear layer 132, a first upper connecting portion 1343 is arranged between the upper side of the first section 1341 and the upper side of the second front layer 141, and a second upper connecting portion 1344 is arranged between the upper side of the second section 1342 and the upper side of the second rear layer 142.

[0025] Among them, the working principle of the non-return guide part 134 is that the two tightly attached first sections 1341 and second sections 1342 are separated to allow the feces to flow downward when the upper chamber 111 is affected by the downward flow of feces and water, and when the lower chamber 112 is inverted to allow the feces and water to gather at the periphery of the first section 1341 and the second section 1342, the hydraulic pressure makes the first section 1341 and the second section 1342 fit tightly to close the conduction between the upper chamber 111 and the lower chamber 112.

[0026] Preferably, the first front layer 131 is made of a transparent material, so that the internal space of the upper chamber 111 can be observed through the first front layer 131 , so that the operator can operate more accurately during alignment because of the internal visibility.

[0027] Preferably, the second rear layer 142 is made of a transparent material so that the internal space of the lower chamber 112 can be observed through the second rear layer 142 , and a volume indicating scale line 1421 is provided on the second rear layer 142 to determine the fecal water collection status in the lower chamber 112 .

[0028] Preferably, the second front layer 141 is made of a non-transparent material, so that the second front layer 141 can block the inner space of the lower chamber 112 from being observed, thereby further improving privacy.

[0029] In addition, a plurality of partition bars 15 are arranged in the collecting chamber 11. Each partition bar 15 is in the shape of a long strip extending left and right and is arranged in a vertical interval. One end of the length and the front and rear sides of each partition bar 15 are respectively connected to the side wall of the collecting chamber 11, and the left and right different ends of adjacent partition bars 15 are connected to the side wall of the collecting chamber 11. The collecting chamber 11 includes a wavy diversion chamber 16 formed by the diversion of each partition bar 15.

[0030] Therefore, a wave-shaped guide cavity 16 is formed under the action of the partition bar 15, so that the feces collected therein are not easy to shake and make noise when the patient moves, thereby further improving privacy.

[0031] In addition, a filling cavity 17 is provided in the partition bar 15 , and a water absorbing member 4 is provided in the filling cavity 17 . The water absorbing member 4 is used to absorb fecal water in the collecting cavity 11 when the partition bar 15 is damaged and the filling cavity 17 and the collecting cavity 11 are connected.

[0032] Therefore, when the bag body 1 is squeezed, the pressure can destroy the partition bar 15 to connect the filling chamber 17 and the collecting chamber 11, so that the feces water is absorbed by the absorbent member 4 to facilitate the garbage disposal and prevent the feces water from flowing out during garbage disposal.

[0033] Specifically, the bag body 1 includes a front layer component and a rear layer component, wherein the front layer component is formed by combining a first front layer 131 and a second front layer 141, and the rear layer component is formed by combining a first rear layer 132 and a second rear layer 142, and a third connecting edge 151 is arranged between the front layer component and the rear layer component to surround and form the outer peripheral wall of the partition strip 15; wherein the third connecting edge 151 includes a first connecting segment 152 with a width of d1 and a second connecting segment 153 with a width of d2, wherein d1>d2, and the filling cavity 17 is squeezed to cause the second connecting segment 153 to break and communicate with the collecting cavity 11.

[0034] Preferably, the water-absorbing member 4 includes a water-soluble film 41 and water-absorbing particles 42 arranged in the water-soluble film 41, so that the water-soluble film 41 wraps the water-absorbing particles 42 and is assembled and used as a whole, making the assembly more convenient, and after the filling chamber 17 and the collecting chamber 11 are connected, the water-soluble film 41 is first dissolved under the action of feces and water to expose the internal water-absorbing particles 42, and then the feces and water are absorbed by the water-absorbing particles 42.

[0035] In addition, a mounting ring 5 is provided at the collecting opening 12, and a mounting plug ring 6 is provided on the pasting plate 2. The mounting ring 5 is sleeved on the outer periphery of the mounting plug ring 6 so that the bag body 1 can be rotatably installed relative to the pasting plate 2; a conduit 51 is provided below the end surface of the mounting ring 5 facing away from the pasting plate 2, and the conduit 51 is provided with a converging surface 511, and the converging surface 511 is an arc-shaped concave surface; the end of the mounting plug ring 6 facing away from the pasting plate 2 extends out of the end surface of the mounting ring 5 facing away from the pasting plate 2; a sponge layer 7 is provided between the outer peripheral wall of the mounting plug ring 6 and the inner peripheral wall of the mounting ring 5; a corrugated ring 22 is provided at the end of the pasting plate 2 facing the mounting plug ring 6, and the end of the corrugated ring 22 facing away from the pasting plate 2 is connected to the mounting plug ring 6.

[0036] Therefore, 1. The mounting ring 5 and the mounting insert ring 6 are rotatably mounted so that the bag body 1 can rotate relative to the adhesive plate 2, that is, when the patient is upright, the bag body 1 faces downward under the action of gravity, so that the fecal water can better enter the lower chamber 112 from the upper chamber 111, and when the patient is lying flat, the bag body 1 is rotated to make the bag body 1 face downward from the waist, so that the fecal water can better enter the lower chamber 112 from the upper chamber 111 to achieve better fecal water collection; 2. The arrangement of the conduit 51 makes it possible that no matter how the bag body 1 rotates, as long as the bag body 1 faces downward as a whole, the conduit 51 can better collect the fecal water flowing out of the stoma and then flow it into the upper chamber 111; 3. The arrangement of the sponge layer 7 can absorb the fecal water leaked between the rotatably mounted insert ring 6 and the mounting ring 5, thereby ensuring the hygiene of the outside of the ostomy bag; 4. The arrangement of the corrugated ring 22 makes the adhesive plate 2 deformable relative to the mounting insert ring 6 to better fit the abdomen.

[0037] In addition, a connecting ring 8 is provided at one end of the mounting collar 5 facing the adhesive plate 2, and a first thin-walled member 91 and a second thin-walled member 92 arranged along a circumferential spacing are provided between the connecting ring 8 and the mounting collar 5, and a ring body formed by the second thin-walled member 92 is located outside the ring body formed by the first thin-walled member 91; the mounting collar 5 is provided with a push-butt portion 52 abutting against the connecting ring 8, and the push-butt portion 52 is located between the ring body formed by the first thin-walled member 91 and the ring body formed by the second thin-walled member 92; the outer portion of the mounting insert ring 6 A first non-return snap ring 61 is arranged around the periphery, and a second non-return snap ring 81 is arranged on the inner periphery of the connecting ring 8; the installing ring 5 is sleeved on the installing plug ring 6 and approaches the pasting plate 2 so that the second non-return snap ring 81 passes over the first non-return snap ring 61, and the first non-return snap ring 61 and the second non-return snap ring 81 restrict the installing ring 5 from escaping from the installing plug ring 6 in the direction away from the pasting plate 2; the connecting ring 8 includes a plurality of split parts 82 arranged circumferentially, and a split gap 83 is arranged between adjacent split parts 82, and a third thin-walled part 93 is arranged in the split gap 83.

[0038] Therefore, 1. The setting of the connecting ring 8 enables the connecting ring 8 and the mounting ring 5 to be separated by axial relative separation under the action of the first thin-walled part 91 and the second thin-walled part 92, and the connecting ring 8 is separated into multiple split parts 82 and removed from the mounting plug ring 6 under the action of the third thin-walled part 93, so that when the bag body 1 needs to be replaced, the adhesive plate 2 does not need to be removed from the bag body, and the bag body 1 can be directly removed and replaced with a new bag body 1. 2. The first non-return snap ring 61 and the second non-return snap ring 81 realize the rapid installation of the bag body 1 and the adhesive plate 2. 3. The push-butt portion 52 prevents the first thin-walled part 91 and the second thin-walled part 92 from being damaged by pressure during the mutual installation of the bag body 1 and the adhesive plate 2.

[0039] In addition, a waist belt 18 or the like is also arranged on the lower bag 14 so that the ostomy bag can be tied to the body through the waist belt 18 to reduce the gravity effect on the adhesive plate 2, making it safer to use.

[0040] Among them, the first connecting edge 133 can be fixedly connected by directly hot-melt pressing or gluing the first front layer 131 and the second rear layer 142, or a sandwich layer can be set between the first front layer 131 and the second rear layer 142 and fixedly connected by hot-melt pressing or gluing. In addition, the second connecting edge 143, the first upper connecting part 1343, the second upper connecting part 1344, and the third connecting edge 151 are set similarly.

[0041] In other embodiments, the adhesive plate 2 is directly attached to the rear side of the bag body 1 so that it does not have a rotation function, but the production is more convenient.

[0042] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
