Description

Technical Field

[0001] This invention relates to the field of drainage tube leakage prevention, specifically a drainage tube kit that uses an ostomy bag to prevent leakage of fluid. Background Technology

[0002] Drainage tubes are commonly used clinical tools for fluid drainage. Their drainage methods primarily rely on passive drainage, which uses manual pinching to generate negative pressure, but also include electric negative pressure drainage and gravity drainage. In clinical practice, some wounds (such as postoperative surgical incisions and chronic ulcers) often produce exudate, which not only easily leads to bed sheet contamination and increases the risk of nosocomial infection, but also makes it difficult to accurately measure the amount of exudate, affecting patient assessment. While ostomy bags can achieve centralized collection of wound exudate, there is a structural contradiction in the compatibility between traditional ostomy bags and drainage tubes—the tube's exit point is prone to seal failure or negative pressure conduction, leading to problems such as exudate overflow, measurement errors, or accelerated exudate outflow. Therefore, a ostomy bag-drainage tube co-fitting system that combines reliable sealing, negative pressure blockage at the wound site, and exudate recovery for improved accurate measurement is a key technological direction for solving clinical pain points and improving the quality of nursing care. Summary of the Invention

[0003] The purpose of this invention is to provide a drainage tube kit that uses ostomy bag anti-leakage fluid to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a drainage tube kit for preventing leakage through an ostomy bag, comprising an internal drainage tube and an external drainage tube providing negative pressure. The internal drainage tube is located inside the body for drainage, and the external drainage tube has negative pressure to draw out the liquid. It also includes an ostomy bag, the bottom of which is provided with an arc-shaped liquid storage section for collecting and concentrating the liquid. An installation port is provided on the inner wall of the ostomy bag facing the opening. The installation port is connected to the internal drainage tube on the left side and the external drainage tube on the right side through a connector. The connector is used to connect the internal drainage tube and the external drainage tube. It also includes a liquid extraction mechanism for drawing out the liquid in the storage section.

[0005] Preferably, the connector includes a retaining ring installed on the installation port, and a tubular left interface connected to the left end and a tubular right interface connected to the right end of the retaining ring. The left drainage tube is fitted onto the left interface for fixed connection, and the external drainage tube is fitted onto the right interface for fixed connection. It can also be removed for replacement, and the retaining ring in the middle plays a supporting and fixing role.

[0006] Preferably, the liquid extraction mechanism includes an outer conduit connected to the bottom of the storage section, and the other end of the outer conduit is connected to an external drainage tube. The outer conduit is equipped with a clamping switch. When the switch is opened, the liquid in the storage section can be drained and collected. When closed, the negative pressure of the external drainage tube will not affect the ostomy bag through the outer conduit, ensuring that there is no negative pressure at the wound and preventing the exudate from flowing out faster.

[0007] Preferably, the liquid extraction mechanism includes an inner conduit connected to the inner drainage tube, and the inner conduit is located inside the ostomy bag. The end of the inner conduit is connected to a liquid suction mechanism for absorbing liquid from the storage compartment. The liquid suction mechanism opens to draw liquid after the liquid reaches a set amount, and closes when there is no liquid or the set amount has not been reached to avoid negative pressure in the ostomy bag. The suction mechanism only opens when there is a certain amount of liquid in the storage compartment, ensuring that it will not open when there is no liquid or very little liquid, thereby avoiding negative pressure in the ostomy bag. This ensures that there is not a lot of liquid in the storage compartment, and the liquid can be removed in a timely manner. Of course, the storage amount here can be ignored, or a value can be determined based on experiments and included in the total drainage volume.

[0008] Preferably, the liquid extraction mechanism includes an arc-shaped base that fits against the bottom of the storage section, and a vertically upward guide tube is fixed inside the base. The lower end of the inner guide tube is connected to the upper end of the guide tube, and a liquid inlet is provided on the guide tube. It also includes a floating mechanism that moves upward using the buoyancy of the liquid. The floating mechanism is installed on the guide tube so that it opens the liquid inlet after moving upward. When there is liquid in the storage section, the floating mechanism floats up and opens the liquid inlet to extract the liquid.

[0009] Preferably, the floating mechanism is a floating ball fitted onto the guide tube. It can be a rigid hollow sphere with a vertical channel in the middle that cooperates with the guide tube and also blocks the liquid inlet hole.

[0010] Preferably, the two sides of the floating ball are connected to elastic rubber lines, and the other end of the rubber lines is connected to the base to generate elastic tension, so as to prevent the floating ball from falling out of the liquid inlet due to shaking. At this time, the amount of liquid storage required to balance the rubber lines is a fixed value through experimentation, which can be included in the total drainage volume to ensure accuracy.

[0011] Preferably, the base is fixed to the storage section, and when the ostomy bag is slowly twisted, the storage section remains at the bottom due to its resilience, ensuring normal drainage.

[0012] Preferably, the base rests against the storage section and can slide along the bottom of the storage section when the drainage bag rotates and twists. When the ostomy bag twists rapidly, the base can always remain at the bottom and slide along the storage section to ensure normal drainage.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. One end of the internal drainage tube is connected to the left interface of the connector. It is inserted into the patient's body through the opening on the left side of the ostomy bag. Then, the ostomy bag is attached around the wound. The other end of the connector is connected to the external drainage tube to achieve drainage. Exudate will enter the ostomy bag and be collected to prevent spillage and dripping. The connector effectively combines the ostomy bag and the drainage tube to prevent exudate from flowing out. 2. The fluid collected in the ostomy bag can be discharged into the external drainage tube through the external catheter by opening the switch, and then closed after discharge to avoid the negative pressure of the external drainage tube affecting the ostomy bag and to ensure the normal pressure inside the ostomy bag. 3. With the internal catheter, after the liquid is stored in the storage section, the floating ball moves upward under the action of buoyancy, exposing the inlet hole. The pressure of the internal drainage tube is used to draw away the liquid. After the liquid is drawn away, the floating ball descends and seals the inlet hole, thus ensuring that there is no negative pressure in the storage section after the liquid is drawn away. This avoids the ostomy bag from generating negative pressure and accelerating leakage, which is more reasonable and appropriate. This achieves automatic liquid drawing when there is liquid and automatic closing when the liquid is drawn away, without generating negative pressure in the ostomy bag. It is simple and convenient.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0017] Please see Figures 1 to 3This invention provides a drainage tube kit for preventing leakage through an ostomy bag: a drainage tube kit for preventing leakage through an ostomy bag includes an internal drainage tube 1 and an external drainage tube 2 that provides negative pressure. The internal drainage tube 1 is located inside the body for drainage, and the external drainage tube 2 has negative pressure to draw out the liquid. It also includes an ostomy bag 3, with an arc-shaped liquid storage section 4 at the bottom of the ostomy bag 3 for collecting and concentrating the liquid. The inner wall of the ostomy bag 3 facing the opening has an installation port. The installation port is connected to the internal drainage tube 1 on the left and the external drainage tube 2 on the right via a connector 5. The connector 5 is used to connect the internal drainage tube 1 and the external drainage tube 2. It also includes a liquid extraction mechanism for drawing out the liquid in the storage section 4.

[0018] The connector 5 includes a retaining ring installed on the installation port, a tubular left interface connected to the left end of the retaining ring, and a tubular right interface connected to the right end. The left drainage tube 1 is fitted onto the left interface for fixed connection, and the external drainage tube 2 is fitted onto the right interface for fixed connection. It can also be removed for replacement. The retaining ring in the middle plays a supporting and fixing role.

[0019] The fluid extraction mechanism includes an outer conduit 6 connected to the bottom of the storage section 4, and the other end of the outer conduit 6 is connected to the external drainage tube 2. The outer conduit 6 is equipped with a clamping switch 7. When the switch 7 is opened, the fluid in the storage section 4 can be drained and collected. When closed, the negative pressure of the external drainage tube 2 will not affect the ostomy bag 3 through the outer conduit 6, ensuring that there is no negative pressure at the wound and preventing the exudate from flowing out faster. Example

[0020] like Figures 4 to 7 Compared to Embodiment 1, the difference lies in the different liquid extraction mechanism. The liquid extraction mechanism includes an inner conduit 8 connected to the inner drainage tube 1, and the inner conduit 8 is located inside the ostomy bag 3. The end of the inner conduit 8 is connected to a liquid suction mechanism for absorbing liquid from the storage section 4. The liquid suction mechanism opens to draw liquid after the liquid reaches a set amount, and closes when there is no liquid or the set amount has not been reached to avoid negative pressure in the ostomy bag 3. The suction mechanism only opens when there is a certain amount of liquid in the storage section 4, ensuring that it will not open when there is no liquid or very little liquid, thereby avoiding negative pressure in the ostomy bag 3. This ensures that there is not a lot of liquid in the storage section 4, and the liquid is removed in time. Of course, the storage amount here can be ignored, or a value can be determined based on experiments and included in the total drainage volume.

[0021] The liquid extraction mechanism includes an arc-shaped base 9 fitted to the bottom of the storage section 4, with a vertically upward guide tube 10 fixed inside the base 9. The lower end of the inner guide tube 8 is connected to the upper end of the guide tube 10, and the guide tube 10 has a liquid inlet hole 11. It also includes a floating mechanism that moves upward using liquid buoyancy. The floating mechanism is mounted on the guide tube 10 to open the liquid inlet hole 11 after moving upward. When there is liquid in the storage section 4, the floating mechanism floats up, opens the liquid inlet hole 11, and extracts the liquid. The floating mechanism is a floating ball 12 fitted onto the guide tube 10. It can be made of a rigid hollow sphere or a rubber bladder material, with a vertical channel in the middle that cooperates with the guide tube 10 and also blocks the liquid inlet hole 11. As a preferred embodiment, the float 12 is connected to two sides by elastic rubber lines 13, and the other end of the rubber lines 13 is connected to the base 9 to generate elastic tension, preventing the float 12 from detaching from the inlet hole 11 due to shaking. At this time, the amount of liquid storage required to balance the rubber lines 13 is determined to be a fixed value through testing, which can be included in the total drainage volume to ensure accuracy. The base 9 is fixed on the storage part 4. When the ostomy bag 3 is slowly twisted, the storage part 4 remains at the bottom due to its flexibility, ensuring normal drainage. Example

[0022] Compared to embodiment 2, here the base 9 rests against the storage section 4 and can slide along the bottom of the storage section 4 when the drainage bag 3 rotates and twists. When the ostomy bag 3 twists rapidly, the base 9 can always be located at the bottom and slide along the storage section 4 to ensure normal drainage.

[0023] It should be noted that the environment in which this is used can be one where negative pressure is generated by hand-squeezing, or one where continuous negative pressure drainage is used, such as when connected to a central negative pressure pipeline. Of course, it can also be used for natural drainage, so the application is flexible.

[0024] Working principle: One end of the internal drainage tube 1 is connected to the left interface of the connector 5. It is inserted into the patient's body through the opening on the left side of the ostomy bag 3. Then, the ostomy bag 3 is attached around the wound. The other end of the connector 5 is connected to the external drainage tube to achieve drainage. Exudate will enter the ostomy bag 3 and be collected to prevent spillage and dripping. The connector 5 effectively connects the ostomy bag 3 and the drainage tube to prevent exudate from flowing out. The fluid collected in the ostomy bag 3 can be discharged into the external drainage tube 2 through the external conduit 6 by opening the switch 7, and then closed after discharge to avoid the negative pressure of the external drainage tube 2 affecting the ostomy bag 3 and to ensure the normal pressure in the ostomy bag 3. With the inner catheter 8 in place, after the liquid is stored in the storage section 4, the floating ball 12 moves upward under the action of buoyancy, exposing the inlet hole 11. The pressure of the inner drainage tube 1 is used to draw away the liquid. After the liquid is drawn away, the floating ball 12 descends and seals the inlet hole 11, thereby ensuring that there is no negative pressure after the liquid in the storage section 4 is drawn away. This avoids the ostomy bag 3 from generating negative pressure and accelerating leakage, which is more reasonable and appropriate. This achieves automatic liquid extraction when there is liquid and automatic closing when the liquid is drawn away, without generating negative pressure in the ostomy bag 3. It is simple and convenient.
