Description

Technical Field

[0001] This utility model belongs to the field of medical equipment technology and relates to a fecal drainage device for an enterostomy. Background Technology

[0002] A colostomy is a medical procedure performed after surgery to open a portion of the intestine through an artificial opening in the abdominal wall. The intestine is cut open or moved to allow waste products, such as feces and gas, to be drained. It is typically used for patients who are unable to defecate normally due to illness, injury, surgery, or other reasons.

[0003] To provide better care for patients, a drainage tube needs to be placed at the enterostomy site to help control the excretion of intestinal contents, prevent leakage into the abdominal cavity or surrounding tissues, and reduce the risk of infection.

[0004] To this end, Chinese patent application (application number: 201721351905.9) discloses a fecal diversion device for a double-lumen intestinal fistula, including a "V"-shaped bend made of rubber. Airbags are arranged around the outer sides of both ends of the bend, and one end is provided with a one-way valve. The airbags are connected to an inflation tube.

[0005] However, the above method has the following drawbacks: 1. The curved tube is made of rubber, which is soft and easily bends and deforms when inserted into the intestine, making it difficult to precisely control its direction to pass through the fistula, thus increasing the operational difficulty. 2. The curved tube is fixed to the intestine by inflating the balloon and adhering it to the intestinal wall, allowing the curved tube to properly divert feces. If the balloon is not inflated enough, or if gas leaks during use, the balloon may not fully inflate, potentially causing the connection between the curved tube and the intestine to loosen, meaning the device has poor stability. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a fecal drainage device for an enterostomy. The technical problem to be solved by this invention is: how to achieve stable fixation of the device while keeping its operation simple.

[0007] The purpose of this utility model can be achieved through the following technical solution: a fecal drainage device for an enterostomy, comprising a curved tube and an air bladder, characterized in that the drainage device further comprises a base plate and two rigid drainage tubes, the base plate being made of an adhesive material and having a window, the drainage tubes being fitted with an air bladder on the outside, and the drainage tubes being detachably connected to the curved tubes and clamped and fixed with a connector, the connector being fixedly connected to the base plate.

[0008] During installation, the base plate is adhered to the skin around the stoma. The ends of the two drainage tubes connected to the balloon are inserted into the window of the base plate and then inserted into the corresponding intestines. After the balloons inflate, they adhere to the intestinal wall, fixing the drainage tubes to the intestines. The two ends of the curved tube are then connected and fixed to the corresponding drainage tubes, and the fixing connectors are clamped to secure the drainage tubes to the base plate. The drainage tubes are fitted with inflatable, soft balloons that extend into the intestines, allowing for prolonged placement without compressing or puncturing the intestinal wall. The drainage tubes themselves are rigid and will not bend or deform during insertion, allowing for easy directional control to facilitate smooth passage through the fistula opening, ensuring safety while minimizing operational difficulty. The drainage tubes are fixed to the intestines by balloon inflation and to the base plate via connectors, providing double fixation to prevent dislodgement and ensure stable device fixation. The connectors are fixed to the base plate, while the drainage tubes and curved tubes are detachably connected. The clamping and fixing connectors facilitate disassembly, replacement, and cleaning, making assembly convenient and highly flexible.

[0009] The aforementioned fecal drainage device for an enterostomy includes a fixing ring and a connecting strip as the connecting component. The fixing ring is fitted onto the corresponding drainage tube and clamped and fixed by the drainage tube and the bend. The connecting strip is fixed at both ends to the fixing ring and the base, respectively. Compared to directly clamping and fixing the connecting strip between the drainage tube and the bend, clamping and fixing the fixing ring between the drainage tube and the bend effectively increases the stress-bearing area of ​​the connecting component, allowing for a more even distribution of pressure and tension, and avoiding excessive local stress at a single connection point. Furthermore, the fixing ring fitted onto the drainage tube effectively resists outward circumferential tension, further increasing the stability and tensile strength of the device.

[0010] The aforementioned fecal drainage device for enterostomy sites includes a connecting strip made of a stretchable material. Since the condition of an enterostomy site may vary between patients, and even within the same patient, it may change over time, the stretchable material allows for flexible adjustment of the connecting strip's length to adapt to the actual condition of the stoma. Furthermore, during patient activity, the skin at the stoma site may be stretched; the stretchable material of the connecting strip helps to distribute these forces more evenly, preventing patient injury and device loosening.

[0011] The aforementioned enterostomy fecal drainage device features a retractable plastic tube. This retractable tube allows for adjustment of its length or shape to meet the specific needs of different patients, ensuring an optimal personalized fit for each individual. This flexibility is particularly important for patients requiring long-term use of enterostomy devices, allowing for better adaptation to changes in their condition or the stoma during recovery. Furthermore, the smooth surface of the plastic tube makes it easy to clean, avoiding the problems of dirt accumulation or aging that can occur with rubber materials. This facilitates daily care and cleaning for patients and healthcare personnel, reducing the risk of bacterial infection.

[0012] In the aforementioned enterostomy fecal drainage device, the two drainage tubes are threadedly connected to the ends of the bends. This threaded connection not only provides stable fixation but also simplifies disassembly, requiring only a rotation, greatly simplifying the disassembly and replacement process and improving ease of use. Furthermore, threaded connections typically reduce the risk of leakage by increasing the tightness of the contact surfaces. For intestinal drainage devices, ensuring that the tube connections are leak-free (no fluid or feces) is crucial to effectively reduce the risk of infection.

[0013] In the aforementioned enterostomy fecal drainage device, the connection between the drainage tube and the curved tube clamps the fixing ring and the connecting strip. The fixing connection between the fixing ring and the connecting strip is also within the clamping range, further ensuring reliable fixation between the fixing ring and the connecting strip.

[0014] The aforementioned fecal drainage device for enterostomy includes a ring-shaped base as the connecting component. This base is made of a rigid material and is fixedly connected to the chassis. The base's supporting force effectively distributes tensile and compressive forces from different directions, reducing excessive local stress at any connection point and thus extending the device's service life. Furthermore, the rigid material used for the base effectively ensures that the chassis window does not deform during long-term use, significantly improving the device's stability and reliability.

[0015] In the aforementioned fecal drainage device for the enterostomy, the two drainage tubes are connected to the ends of the curved tubes via pins. Pin connections eliminate the need for complex contact surfaces, reducing the accumulation of dirt in gaps and lowering the risk of infection due to bacterial growth. Furthermore, pin connections facilitate disassembly and replacement, improving ease of use.

[0016] Compared with existing technologies, this enterostomy fecal drainage device has the following advantages:

[0017] 1. In this enterostomy fecal drainage device, the drainage tube is fitted with an inflatable soft air bladder that extends into the intestine. It can be left in place for a long time without compressing or puncturing the intestinal wall. The drainage tube itself is rigid and will not bend or deform when inserted into the intestine. Its direction can be easily controlled to allow it to pass smoothly through the fistula, ensuring safety while reducing the difficulty of operation.

[0018] 2. In this enterostomy fecal drainage device, the drainage tube is fixed to the intestine by inflating the balloon and fixed to the base plate by the connector. This double fixation prevents the drainage tube from falling out and ensures the stable fixation of the device.

[0019] 3. In this enterostomy fecal drainage device, the connector is fixed to the chassis, the drainage tube and the bend are detachably connected, and the drainage tube and the bend are clamped and fixed to the connector, which is convenient for disassembly, replacement and cleaning, and is easy to assemble and highly flexible.

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0027] Example 1:

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the fecal drainage device for the enterostomy includes a bend 1, an air bladder 2, a base 3, and two rigid drainage tubes 4. The base 3 is made of an adhesive material and has a window 5. An inflatable air bladder 2 is fitted on the outside of the drainage tube 4, and the drainage tube 4 is detachably connected to the bend 1 and clamped and fixed with a connector 6.

[0029] Specifically, the base 3 is ring-shaped and made of self-adhesive protective adhesive, which can form a dense bond with the skin. It can be used by simply tearing off the covering film.

[0030] The connector 6 includes a fixing ring 6a, a connecting strip 6b, and a ring-shaped base. The fixing ring 6a is fitted onto the corresponding drainage tube 4 and clamped and fixed by the drainage tube 4 and the bend 1. The two ends of the connecting strip 6b are fixed to the fixing ring 6a and the base 3, respectively. By directly clamping and fixing the connecting strip 6b to the drainage tube 4 and the bend 1, and clamping and fixing the fixing ring 6a to the drainage tube 4 and the bend 1, the stress-bearing area of ​​the connector 6 can be effectively increased, allowing the pressure and tension to be distributed more evenly and avoiding excessive local stress at a single connection point. In addition, the fixing ring 6a, fitted onto the drainage tube 4, can effectively resist outward circumferential tension, further increasing the stability and tensile strength of the device.

[0031] Specifically, the connecting strip 6b is made of a stretchable material, such as stretchable plastic. The condition of the stoma may vary from patient to patient, and even the stoma of the same patient may change over time. Making the connecting strip 6b from a stretchable material allows for flexible adjustment of its length according to the actual condition of the stoma, adapting it to real-time changes. Furthermore, during patient movement, the skin at the stoma site may be stretched. The stretchable material of the connecting strip 6b helps to distribute these forces more evenly, preventing patient injury and device loosening.

[0032] The base is made of rigid material and is fixedly connected to the chassis 3. The supporting force of the base can effectively distribute the tensile and compressive forces from different directions, reducing excessive local stress at any connection point, thereby extending the service life of the device. Moreover, the rigid material of the base can effectively ensure that the window 5 of the chassis 3 will not deform during long-term use, effectively improving the stability and reliability of the device.

[0033] Specifically, one end of the connecting strip 6b extends out of the inner side of the base and is fixed to the fixing ring 6a, while the other end extends out of the outer side of the base and is bonded to the chassis 3.

[0034] Bend 1 is a retractable plastic tube. Its retractable design allows for adjustment of length or shape to meet the specific needs of different patients, ensuring an optimal personalized fit for each individual. This flexibility is particularly important for patients requiring long-term use of enterostomy devices, allowing for better adaptation to changes in their condition or the stoma during recovery. Furthermore, the smooth surface of the plastic tube makes it easy to clean, avoiding the problems of dirt accumulation or aging that can occur with rubber materials. This facilitates daily care and cleaning for patients and healthcare professionals, reducing the risk of bacterial infection.

[0035] The drainage tube 4 has an air bladder 2 at one end and a threaded tube at the other end. Both ends of the bend 1 are equipped with nuts, which can be threaded into the threaded tube of the drainage tube 4. This threaded connection not only provides stable fixation but also simplifies disassembly, requiring only a rotation, greatly simplifying the disassembly and replacement process and improving ease of use. Furthermore, the threaded connection typically reduces the risk of leakage by increasing the tightness of the contact surfaces. For intestinal drainage devices, ensuring that the tube connections are leak-free (no fluid or feces) is crucial to effectively reduce the risk of infection.

[0036] The two drainage tubes are divided into a fecal inlet tube and a fecal outlet tube. A one-way valve is installed at the connection between the two. The fecal outlet tube only allows feces to flow out to one end of the threaded tube, and the fecal inlet tube only allows feces to flow into one end of the threaded tube.

[0037] The diameter of the threaded tube of the drainage tube 4 is slightly smaller than the diameter of the main body of the drainage tube 4, and the diameter of the nut of the bend tube 1 is slightly larger than the diameter of the main body of the bend tube 1. Both the diameter of the main body of the drainage tube 4 and the diameter of the nut of the bend tube 1 are larger than the diameter of the retaining ring 6a. That is, the main body of the drainage tube 4 and the threaded tube form a stepped surface. The retaining ring 6a is fitted onto the threaded tube and placed on the stepped surface. The end face of the nut of the bend tube 1 and the end face of the main body of the drainage tube 4 clamp and fix the retaining ring 6a, simultaneously clamping and fixing the connection between the retaining ring 6a and the connecting strip 6b. This dimensional difference not only ensures a more reliable clamping of the retaining ring 6a, but also ensures that the connection between the retaining ring 6a and the connecting strip 6b is within the clamping range, further guaranteeing reliable fixation between the retaining ring 6a and the connecting strip 6b.

[0038] Specifically, the outer periphery of the drainage tube 4, except for the threaded tube part which is connected to the nut of the bend tube 1 by thread and is not wrapped by the air bag 2, is completely wrapped by the air bag 2. The rigid body of the drainage tube 4 is not directly exposed in the intestinal lumen.

[0039] Example 2:

[0040] The technical solution in this embodiment is basically the same as that in Embodiment 1, except that in this embodiment, the two drainage tubes 4 are respectively connected to the ends of the bend 1 by pins. Pin connections do not require complex contact surfaces, reducing the accumulation of dirt in gaps and lowering the risk of infection due to bacterial growth. Furthermore, pin connections are easy to disassemble and replace, improving ease of use.

[0041] During installation, first clean and dry the skin around the stoma. Then, remove the film from the base plate 3 and attach the base plate 3 to the skin around the stoma, ensuring that the two connecting strips 6b are aligned with the stoma inlet and outlet. Adjust the spacing of the two connecting strips 6b according to the actual stoma inlet and outlet. Insert the ends of the two drainage tubes 4 connected to the balloon 2 into the window 5 of the base plate 3 and insert them into the corresponding intestines. After the balloon 2 is inflated, it adheres to the intestinal wall, fixing the drainage tubes 4 to the intestines. Then, put the fixing ring 6a on the drainage tubes, connecting and fixing both ends of the curved tube 1 to the corresponding drainage tubes 4, and clamp and fix the fixing ring 6a to secure the drainage tubes 4 to the base plate 3. Finally, seal the entire device with an ostomy bag. The drainage tube 4 is fitted with an inflatable, soft balloon 2 that extends into the intestine, allowing for prolonged placement without compressing or puncturing the intestinal wall. The tube itself is rigid, preventing bending or deformation during insertion and allowing for easy directional control to facilitate passage through the fistula opening, ensuring safety and minimizing operational difficulty. The drainage tube 4 is secured to the intestine by the inflated balloon 2 and further fixed to the base plate 3 via a connector 6, providing double fixation to prevent dislodgement and ensure stable device fixation. The connector 6 is fixed to the base plate 3, and the drainage tube 4 and the curved tube 1 are detachably connected. The connector 6 clamps the drainage tube 4 and curved tube 1 together, facilitating disassembly, replacement, and cleaning, and offering convenient and flexible assembly. Furthermore, this device provides excellent drainage; the large diameter of the drainage tube 4 prevents reflux and effectively diverts feces. The balloon 2 effectively seals the intestinal tract, and the fecal drainage tube is fixed to the base plate 1, preventing dislodgement. When used in conjunction with an ostomy bag, fecal leakage is completely prevented.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
