Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a device for collecting stool from an enterostomy. Background Technology

[0002] An enterostomy is a surgical procedure that connects the intestinal cavity to the abdominal wall to facilitate the drainage of waste products, which typically include feces and urine. These products are usually collected and protected using an ostomy bag.

[0003] Existing ostomy bags generally consist of a base and a bag body. The base typically comprises a base and a mounting bracket, while the bag body usually consists of a cassette and the bag itself. The process usually begins by measuring the size of the stoma, then cutting the corresponding mounting hole in the base with scissors. The mounting hole is then fitted over the stoma, the base is attached to the body, and finally, the cassette is fastened to the mounting bracket. Diarrhea then flows through the stoma into the ostomy bag for collection. However, during use, the bags often stick together due to negative pressure. On the first use, obstructed excrement spray can splash onto the skin and stoma, causing contamination of the stoma and surrounding skin. If not cleaned, this can lead to stoma infection. Furthermore, uneven or non-round cuts during the cutting of the mounting hole can affect installation. The bag's large opening due to mishandling can cause leakage of excrement during use. When collecting a certain amount of excrement, the bag itself is discarded, wasting materials such as the card holder. Furthermore, its relatively high price and frequent replacements increase the financial burden on most families. Additionally, the card holder's height means that some excrement may remain inside during collection, potentially leading to bacterial growth and infections of the stoma and surrounding skin. Moreover, patient movements can compress the bag, causing excrement to flow from the bag into the card holder and back into the card holder. When the patient is lying supine, the bag cannot rotate, and its stacking and bending can impair its use. Therefore, this application provides a device for collecting feces from the stoma to meet this need. Summary of the Invention

[0004] The technical problem this invention aims to solve is to provide a device for collecting feces from an enterostomy, addressing the issues of existing ostomy bags. These bags typically stick together due to negative pressure during use, leading to splashing of excrement onto the skin and enterostomy during first use due to obstructed discharge, causing contamination of the enterostomy and surrounding skin. Without cleaning, this can lead to infection of the enterostomy. Furthermore, uneven or non-round cuts during installation can affect installation, and incorrect cuts can result in large gaps, causing leakage of excrement during use. Additionally, after collecting a certain amount of excrement, the bag may become clogged. Discarding the bag leads to waste of materials such as the card holder. Furthermore, its relatively high price and frequent replacements increase the financial burden on most families. Additionally, the card holder's height means that some excrement may remain inside during collection, potentially causing bacterial growth and infections of the stoma and surrounding skin. Moreover, patient movements can compress the bag, causing excrement to flow from the bag into the card holder and back into the card holder. When the patient is lying down, if the bag cannot rotate, its stacking and bending can impair its usability.

[0042] like Figures 1 to 10As shown, an embodiment of the present invention provides a device for collecting feces from an enterostomy, including a chassis mechanism 1. The chassis mechanism 1 includes a first base plate 11 adhered to the human body, a second base plate 12 disposed within the first base plate 11, and a retaining seat 14 provided on one side wall of the first base plate 11. The second base plate 12 includes a first engaging ring plate 121 fixedly connected to the inner ring of the first base plate 11, and a plurality of second engaging ring plates 122 sequentially engaging the first engaging ring plate 121. The diameters of the plurality of second engaging ring plates 122 decrease sequentially from the outside to the inside. Plate 121 includes a first fixing ring fixedly connected to the inner ring of the first base plate 11. The bottom end of the first fixing ring is provided with a first limiting groove. The second engaging ring plate 122 includes a first annular locking block 123 that is engaged in the first limiting groove. One end of the first annular locking block 123 is sequentially fixedly connected to an L-shaped plate 124 and a first annular plate 126. The bottom of the first annular locking block 123 is at the same level as the bottom of the first engaging ring plate 121, and the top of the first annular locking block 123 is at the same level as the top of the first engaging ring plate 121.

[0043] The bottom end of the first annular plate 126 is provided with a second limiting groove 125. The next first annular block 123, which is close to the first locking annular plate 121, is engaged in the outermost second limiting groove 125. Multiple second locking annular plates 122 are engaged in sequence from the outside to the inside. The innermost second locking annular plate 122 is engaged with a third locking annular plate 127. The third locking annular plate 127 includes a fixedly connected third locking annular plate and a cylinder. The third locking annular plate is engaged with the innermost second limiting groove 125. The outer wall of the fixed column is in contact with the inner wall of the innermost first annular plate 126. The top and bottom of the fixed column are on the same horizontal plane as the top and bottom of the first annular plate 126, respectively.

[0044] By setting the second base plate 12, during use, the engagement between the third locking ring plate 127 and the second locking ring plate 122, as well as the engagement between the second locking ring plates 122 and the second locking ring plates 122, can be released according to the size of the stoma. This avoids the operator having to manually cut the installation hole with scissors, saving operation time. It also avoids uneven or non-round cuts that may affect installation, and avoids large gaps caused by cutting errors, thus preventing leakage of excrement during use after installation. The collection mechanism 2 is used to collect stoma stool. The collection mechanism 2 is connected to the card seat 14. The collection mechanism 2 includes a blocking component 21, a material blocking component 23, an anti-backflow component 24, and a material receiving component 26 connected to each other. The anti-backflow component 24 is set inside the material blocking component 23.

[0045] like Figures 3 to 5 , Figure 8As shown, the card holder 14 includes a first annular piece 144 fixedly connected to the side wall of the first base plate 11. An annular block 141 is fixedly connected to the side wall of the first annular piece 144. A plurality of evenly distributed first discharge holes 142 and second discharge holes 143 are provided on the circumference of the side wall of the annular block 141. The multiple first discharge holes 142 and second discharge holes 143 are provided to facilitate the discharge of excrement when the patient is lying down or standing. The inner bottom wall of the first discharge hole 142 is inclined. The height of the side of the first discharge hole 142 near the first locking ring plate 121 is lower than the height of the other side to facilitate the discharge of excrement.

[0046] The second discharge hole 143 is inclined. The bottom of the opening of the second discharge hole 143 near the first locking ring plate 121 is at the same level as one side wall of the first locking ring plate 121. The height of the opening of the second discharge hole 143 near the first locking ring plate 121 is lower than the height of the opening at the other end. In order to facilitate the collection of excrement remaining in the annular block 141 and avoid accumulation between the annular block 141 and the second base plate 12, and further avoid contamination at the enterostomy site, a first groove is provided between the first discharge hole 142 and the second discharge hole 143 on the inner wall of the annular block 141. A second groove is provided between the second discharge hole 143 and the first annular piece 144 on the outer wall of the annular block 141. The first groove and the second groove are provided to facilitate the stable installation of the blocking component 21.

[0047] like Figure 3 , Figure 4 and Figure 7 As shown, the blocking assembly 21 includes a second annular piece 211 that fits against the side wall of the first annular piece 144. A U-shaped retaining ring 212, which is snapped onto the annular block 141, is fixedly connected to the inner ring of the second annular piece 211. A third annular piece 213, which fits against the first engaging ring plate 121, is fixedly connected to the U-shaped retaining ring 212 to block excrement and prevent it from seeping out from the bottom of the U-shaped retaining ring 212. A retaining groove is fixedly connected to the inner wall of the U-shaped retaining ring 212. The first locking ring 214 and the second locking ring 215 are locked in the second locking groove. A guide plate 216 is fixedly connected to the U-shaped locking ring 212. The U-shaped locking ring 212, the first locking ring 214 and the second locking ring 215 are set to facilitate the cleaning and disinfection of the guide plate 216. At the same time, the U-shaped locking ring 212 can block the other non-discharging second discharge hole 143 and the first discharge hole 142 to prevent the discharge from leaking.

[0048] The deflector plate 216 is made of transparent material. In order to block and prevent splashing of patient excrement, the deflector plate 216 and the U-shaped retaining ring 212 are provided with a third discharge hole 217. In order to facilitate the collection of patient excrement, the third discharge hole 217 is connected to the first discharge hole 142 and the second discharge hole 143. The width of the third discharge hole 217 is wider than the width of the first discharge hole 142, and the width of the first discharge hole 142 is wider than the width of the second discharge hole 143. A first annular retaining plate 218 is provided around the third discharge hole 217 and is fixedly connected to the outer wall of the deflector plate 216. A fourth discharge hole of the same size as the third discharge hole 217 is provided on the first annular retaining plate 218 and is connected to the third discharge hole 217.

[0049] To prevent obstruction of excrement discharge, a first annular groove is provided around the outer wall of the first annular slot plate 218. An annular rubber sheet 219 is fixedly connected inside the first annular groove. A second annular groove is provided around the outer wall of the annular rubber sheet 219. The first annular slot plate 218 is designed to facilitate the installation and disassembly of the material blocking assembly 23, and further facilitate internal cleaning.

[0050] The second annular plate 211, the U-shaped retaining ring 212, and the guide plate 216 are an integral structure. The first retaining ring 214 and the second retaining ring 215 are both made of rubber. The purpose of setting the first retaining ring 214 and the second retaining ring 215 is to increase the connection stability between the U-shaped retaining ring 212 and the annular block 141 and increase the sealing between them. At the same time, the properties of the rubber material increase the friction between the first retaining groove and the first retaining ring 214, as well as the second retaining groove and the second retaining ring 215, so that the U-shaped retaining ring 212 and the annular block 141 can be relatively positioned. The height of the end of the guide plate 216 away from the third discharge hole 217 is greater than the height of the end near the third discharge hole 217. The side wall of the guide plate 216 away from the U-shaped retaining ring 212 is set in an inward arc shape to facilitate the guidance of excrement, and also to avoid the accumulation of excrement and to avoid the splashing of excrement and contamination of the patient's skin and enterostomy site.

[0051] With the cooperation of the card holder 14 and the blocking component 21, when the excrement is sprayed outward during use, it will come into contact with the inner wall of the guide plate 216. Due to the influence of the shape of the inner wall, the excrement will flow along the inner wall of the guide plate 216, avoiding splashing and rebound, and preventing the excrement from adhering to the skin and causing contamination near the stoma. The excrement sprayed into the guide plate 216 will flow out through the third discharge hole 217. When the patient is lying supine, the guide plate 216 can be rotated, which will cause the second annular plate 211 and the U-shaped retaining ring 212 to rotate simultaneously. The rotation stops when the third discharge hole 217 is connected to the next first discharge hole 142. Under the cooperation of the first card slot and the first carding ring 214, as well as the second card slot and the second carding ring 215, the U-shaped retaining ring 212 will be fixed relative to the annular block 141.

[0052] During use, a large amount of excrement flows out through the first discharge hole 142, and some accumulated excrement flows out through the second discharge hole 143, converging into the third discharge hole 217 for discharge. When cleaning is required, by pulling the second annular plate 211 in the opposite direction to the first base plate 11, the second locking ring 215 will be moved out of the second locking groove, and the first locking ring 214 will be moved out of the first locking groove. Furthermore, the U-shaped locking ring 212 will be moved out of the annular block 141, thereby facilitating the guidance of excrement from the enterostomy, avoiding the accumulation of excrement, and preventing the growth of bacteria in the accumulated excrement that could cause infection of the enterostomy and surrounding skin. It also avoids the splashing of excrement that could contaminate the patient's skin and enterostomy, allowing the device to be used even when the patient is lying supine. Furthermore, the portable installation and disassembly make it easy to clean and disinfect the inside.

[0053] like Figure 5 , Figure 6 and Figure 9 As shown, the baffle assembly 23 includes a second annular locking block 232 that is snapped into the second annular groove. The other end of the second annular locking block 232 is fixedly connected to a first baffle cylinder 231. The first baffle cylinder 231 and the second annular locking block 232 are configured to cooperate. During use, the second annular locking block 232 can be conveniently installed and disassembled with the guide plate 216 to clean and disinfect its interior, facilitate the replacement of damaged parts, reduce the frequency of replacement, and save material consumption.

[0054] The first baffle cylinder 231 is connected to the first discharge hole 142, the second discharge hole 143, the fourth discharge hole, and the third discharge hole 217. To facilitate the collection of excrement into the first baffle cylinder 231, mounting holes are provided on both sides of the first baffle cylinder 231. Corrugated sheets 235 are fixedly connected to the mounting holes. To facilitate the expansion of the opening of the first baffle cylinder 231 and its installation with the guide plate 216, the second annular locking block 232 and the two ends of the corrugated sheet 235 are made of elastic material. The other end of the first baffle cylinder 231 is fixedly connected to a second baffle cylinder 236. Both the first baffle cylinder 231 and the second baffle cylinder 236 are made of transparent material. A second annular slot plate 233 is fixedly connected to the outer wall of the other end of 36. A T-shaped card plate 234 sleeved on the second baffle cylinder 236 is engaged in the slot of the second annular slot plate 233. The T-shaped card plate 234 includes an annular block and an annular limiting ring that are fixedly connected. The annular block is engaged in the slot of the second annular slot plate 233. The first baffle cylinder 231, the second annular block 232 and the second baffle cylinder 236 are an integral structure. The side wall of the first baffle cylinder 231 away from the first discharge hole 142 is set in an inward arc shape. The second baffle cylinder 236, the second annular slot plate 233 and the T-shaped card plate 234 are arranged in a coordinated manner to facilitate the installation and removal of the receiving bag 261.

[0055] By setting the baffle assembly 23, during use, if it is necessary to clean the first baffle cylinder 231 and the second baffle cylinder 236, the second baffle cylinder 236 can be forcefully pushed towards the guide plate 216. This will cause the corrugated sheet 235 to be stretched due to the contact between the guide plate 216 and the U-shaped retaining ring 212. Consequently, the openings at both ends of the first baffle cylinder 231 will expand due to the stretching of the corrugated sheet 235. At the same time, the second annular retaining block 232 will expand outward synchronously with the first baffle cylinder 231 due to the elastic material at both ends. This will also cause the second annular retaining block 232 to move out of the annular rubber sheet 219, further causing the first baffle cylinder 231 to expand outward. The first baffle cylinder 231, the second annular locking block 232, and the second baffle cylinder 236 are disengaged from the first annular locking plate 218, which further facilitates the cleaning and disinfection of their interiors. After the cleaning is completed, the opening of the first baffle cylinder 231 is pried open, and through the above principle, it covers the first annular locking plate 218 and contacts the second annular groove. Then, the second baffle cylinder 236 is pulled, so that the second annular locking block 232 enters the second annular groove for limiting. Thus, the portable installation and disassembly facilitate the cleaning and disinfection of their interiors, make it easy to replace damaged parts, reduce the frequency of replacement, and reduce material waste.

[0056] like Figure 3 , Figure 8 and Figure 9As shown, the anti-backflow component 24 includes a first flow-blocking unit 241, a second flow-blocking unit 245, and a third flow-blocking unit 249. By setting the first flow-blocking unit 241, the second flow-blocking unit 245, and the third flow-blocking unit 249, the excrement can be blocked to prevent backflow when the excrement is active or lying down. The length of the first flow-blocking unit 241 is longer than the length of the second flow-blocking unit 245, and the length of the second flow-blocking unit 245 is longer than the length of the third flow-blocking unit 249. A pair of connecting posts 240 are fixedly connected between the first flow-blocking unit 241 and the second flow-blocking unit 245, and between the second flow-blocking unit 245 and the third flow-blocking unit 249. The connecting posts 240 are set to facilitate the support of the first flow-blocking unit 241, the second flow-blocking unit 245, and the third flow-blocking unit 249.

[0057] The first flow-blocking unit 241 includes a first flow-blocking plate 242 fixedly connected to the first baffle cylinder 231, and a first elastic plate 244 fixedly connected to both ends of the first flow-blocking plate 242; the first flow-blocking plate 242 includes a second flow-blocking plate 246 fixedly connected to the first baffle cylinder 231, and a second elastic plate 248 fixedly connected to both ends of the second flow-blocking plate 246.

[0058] The third flow-blocking unit 249 includes a third flow-blocking plate 250 fixedly connected to the first baffle cylinder 231. Both ends of the third flow-blocking plate 250 are fixedly connected to third elastic plates 252. The height of the middle part of the top of the first flow-blocking plate 242 is higher than the height of the first elastic plate 244. The first elastic plate 244 is inclined, with one end fitting against the inner wall of the first baffle cylinder 231. The shape of the first elastic plate 244 is the same as the cavity shape of the first baffle cylinder 231. The height of the end of the first elastic plate 244 closest to the first flow-blocking plate 242 is higher than the other end. The second flow-blocking plate 24... The height of the top middle part of the 6th section is higher than the height of the second elastic plate 248. The second elastic plate 248 is inclined. The height of the end of the second elastic plate 248 near the second baffle plate 246 is higher than the height of the other end. The height of the top middle part of the third baffle plate 250 is higher than the height of the third elastic plate 252. The third elastic plate 252 is inclined. The height of the end of the third elastic plate 252 near the third baffle plate 250 is higher than the height of the other end. The gap distance between the third elastic plate 252 and the inner wall of the second baffle cylinder 236 is greater than the gap distance between the second elastic plate 248 and the inner wall of the first baffle cylinder 231.

[0059] The first baffle plate 242 and the first elastic plate 244 are integral structures made of elastic material. A first weakening groove is provided at the connection between the first elastic plate 244 and the first baffle plate 242. The second baffle plate 246 and the second elastic plate 248 are integral structures made of elastic material. A second weakening groove is provided at the connection between the second baffle plate 246 and the second elastic plate 248. The third baffle plate 250 and the third elastic plate 252 are integral structures. A third weakening groove is provided at the connection between the third baffle plate 250 and the third elastic plate 252. The first baffle plate 242 is close to the second baffle plate. One side wall of the first baffle plate 242, the side wall of the second baffle plate 246 near the third baffle plate 250, and the side wall of the third baffle plate 250 away from the second baffle plate 246 are all arranged in an inwardly concave arc shape. The other side wall of the first baffle plate 242, the second baffle plate 246, and the third baffle plate 250 are all arranged in an outwardly convex arc shape. The first baffle plate 242 is fixedly connected inside the first baffle cylinder 231, the second baffle plate 246 is fixedly connected between the first baffle cylinder 231 and the second baffle cylinder 236, and the third baffle plate 250 is fixedly connected inside the second baffle cylinder 236.

[0060] With the anti-backflow component 24 in place, during use, excrement falls onto the first baffle plate 242 and slides onto the first elastic plate 244. The first elastic plate 244, under pressure, applies force to the first weakening groove, causing it to bend and deform. The excrement then falls directly into the collection bag 261. When the patient lies supine, squats, or bends over, the excrement slides within the collection bag 261 and then interacts with the third... When the flow-blocking unit 249 comes into contact with the excrement, the third flow-blocking unit 249 will block it for the first time. The excrement that fails to be blocked will come into contact with the second flow-blocking unit 245, and the second flow-blocking unit 245 will block it for the second time. The remaining excrement enters between the first flow-blocking unit 241 and the second flow-blocking unit 245 through the gap between the second elastic plate 248 and the first baffle cylinder 231. The first flow-blocking unit 241 will block the remaining excrement, thus preventing the excrement from flowing back when the patient makes limb movements.

[0061] like Figure 1 , Figure 6As shown, the receiving assembly 26 includes a receiving bag 261 sleeved on the second annular groove plate 233. An elastic rope 262 sleeved on the second baffle cylinder 236 is fixedly connected to the open end of the receiving bag 261. The outer wall of the open end of the elastic rope 262 is engaged with the engagement point between the second annular groove plate 233 and the T-shaped clamping plate 234. The inner wall of the elastic rope 262 is in contact with the outer wall of the second baffle cylinder 236. The outer wall of the open end of the receiving bag 261 is located within the groove of the second annular groove plate 233. The annular clamping block is engaged with... The second annular slot plate 233 is in the slot and contacts the outer wall of the receiving bag 261. The bottom end of the annular limiting ring contacts the outer wall of the receiving bag 261. The annular locking block is set to facilitate fixing the receiving bag 261 in the second annular slot plate 233. The annular fiber ring is set to press around its perimeter to prevent the receiving bag 261 from falling off due to weight. The receiving bag 261 has a drawstring 263 on the outer wall near the elastic rope 262. This is the prior art. The receiving bag 261 is made of transparent material.

[0062] During use, firstly, according to the size of the enterostomy, push the cylinder to move the third locking ring plate out of the second limiting groove 125. If a larger hole is needed, push the innermost second locking ring plate 122, which will then move the first annular locking block 123 out of the second limiting groove 125. This process is repeated sequentially. Then, the fitted hole is passed through the enterostomy, and the adhesive first base plate 11, first locking ring plate 121, and second locking ring plate 122 are adhered to the patient's skin. When excrement is ejected, it contacts the inner wall of the guide plate 216 and flows along it. Excrement sprayed into the guide plate 216 flows out through the third discharge hole 217. The outflowing excrement enters the first baffle cylinder 231 and the second baffle cylinder 236, further... Excrement falls onto the first baffle plate 242 and slides onto the first elastic plate 244. The first elastic plate 244, under pressure, applies force to the first weakening groove, causing it to bend and deform. The excrement then falls directly into the collection bag 261. When a large amount accumulates in the collection bag 261, it can be sealed and secured by pulling the drawstring 263. Then, by pulling out the elastic rope 262 and dragging it above the elastic rope 262, the collection bag 261 can be moved out of the second annular slot plate 233. After that, by pulling the opening of the elastic rope 262, it can be moved out of the second baffle cylinder 236, allowing for further processing of the excrement.

[0063] When the patient is lying supine, the guide plate 216 can be rotated, which will cause the second annular plate 211 and the U-shaped retaining ring 212 to rotate simultaneously. The rotation stops when the third discharge hole 217 is connected to the next first discharge hole 142. Under the cooperation of the first retaining groove and the first retaining ring 214, as well as the second retaining groove and the second retaining ring 215, the U-shaped retaining ring 212 will be fixed relative to the annular block 141. During use, a large amount of excrement will flow out through the first discharge hole 142, and some of the accumulated excrement will flow out through the second discharge hole 143, flowing into the third discharge hole 217 for discharge. The discharged excrement will enter the collection bag 261 for collection through the above working principle.

[0064] When the patient lies down, squats, bends over, or performs other limb movements, the excrement slides within the collection bag 261 and comes into contact with the third flow-blocking unit 249. The third flow-blocking unit 249 blocks the excrement for the first time. Excrement that fails to be blocked comes into contact with the second flow-blocking unit 245, which blocks it for the second time. The remaining excrement enters between the first flow-blocking unit 241 and the second flow-blocking unit 245 through the gap between the second elastic plate 248 and the first baffle cylinder 231. The first flow-blocking unit 241 blocks the remaining excrement, preventing the excrement from flowing back when the patient performs limb movements.

[0065] When cleaning is required for the blocking assembly 21, the baffle assembly 23, and the anti-backflow assembly 24, firstly, the second baffle cylinder 236 can be forcefully pushed towards the guide plate 216. This will cause the corrugated sheet 235 to be stretched due to the contact between the guide plate 216 and the U-shaped retaining ring 212. Consequently, the openings at both ends of the first baffle cylinder 231 will widen due to the stretching of the corrugated sheet 235. Simultaneously, the second annular retaining block 232 will expand outward in sync with the first baffle cylinder 231 due to the elastic material at both ends. This will also cause the second annular retaining block 232 to move outward from the annular rubber... The removal of the material block 219 further detaches the first baffle cylinder 231, the second annular locking block 232, and the second baffle cylinder 236 from the first annular locking plate 218, making it easier to clean and disinfect the inside of the baffle assembly 23 and the anti-backflow assembly 24. After the cleaning is completed, the opening of the first baffle cylinder 231 is pried open, and through the above principle, it covers the first annular locking plate 218 and contacts the second annular groove. Then, the second baffle cylinder 236 is pulled, so that the second annular locking block 232 enters the second annular groove for limiting.

[0066] Secondly, by pulling the second annular plate 211 to move in the opposite direction to the first base plate 11, the second locking ring 215 will be moved out of the second locking groove, and the first locking ring 214 will be moved out of the first locking groove. Furthermore, the U-shaped locking ring 212 will be moved out of the annular block 141, which further facilitates the cleaning and disinfection of the guide plate 216, and also allows for the cleaning and disinfection of the inside of the annular block 141 and the enterostomy site.
