Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically a mother-daughter drainage bag with a plastic drainage valve. Background Technology

[0002] Drainage bags are commonly used medical drainage devices in clinical practice, and are widely used in various scenarios such as postoperative, abdominal, thoracic, and biliary drainage.

[0003] Existing conventional drainage bags suffer from drawbacks such as lack of hierarchical storage, precise small-volume measurement, and flexible fluid control design. These drawbacks include unclear readings for small-volume drainage, a single storage mode that cannot adapt to drainage fluctuations, rigid drainage and control methods, increased risk of infection and burden on nursing staff due to frequent operation, and the inability to trace small-volume drainage data at different stages. To address these issues, this invention provides a parent-child drainage bag with a plastic drainage valve. Summary of the Invention

[0004] The purpose of this invention is to provide a mother-daughter drainage bag with a plastic drainage valve to solve the problems mentioned in the background art.

[0005] The technical solution of this invention is: a mother-drainage bag with a plastic drainage valve, comprising a mother drainage bag and a daughter drainage bag. One end of the mother drainage bag is fixedly connected to a mother bag opening, and the other end of the mother drainage bag is fixedly connected to a drain outlet. A mother bag tube is connected inside the mother bag opening. One end of the daughter drainage bag is fixedly connected to a daughter bag opening, and a daughter bag tube is connected inside the daughter bag opening. A flow control box is fixedly connected to one end of the mother bag tube and the daughter bag tube. A drainage tube is fixedly connected to the outside of the flow control box. A fixed side ring is fixedly connected to the inside of the flow control box. A flow divider inner plate is rotatably connected to the inside of the flow control box. The flow divider inner plate is rotatably connected to the fixed side ring. A squeezing plate is fixedly connected to the outside of the flow divider inner plate. A flow divider outer ring is fixedly connected to the side of the squeezing plate away from the flow divider inner plate. A square hole is opened on the inside of the flow divider outer ring. An annular sliding column is slidably engaged inside the fixed side ring. One end of the annular sliding column is fixedly connected to the squeezing plate. A ring is movably sleeved on the outside of the annular sliding column. The inner side of the diverter disc is movably engaged with a fixed post. One end of the fixed post is fixedly connected to a limit plate, and the other end of the fixed post away from the limit plate is fixedly connected to a limit plate. The limit plate is movably engaged with the bottom of the flow control box. The bottom of the diverter disc has a groove adapted to the limit plate. In use: one end of the drainage tube is used to guide the liquid into the interior of the flow control box. When the liquid flow rate is low, the liquid enters the flow control box through the drainage tube. Inside the box, the liquid flows through the square hole in the outer ring of the diversion ring to the sub-bag tube, allowing the liquid to flow into the interior of the sub-bag. When the liquid flow rate is high, the sub-bag tube is thinner than the drainage tube, which pushes the squeezing plate to rotate, squeezing the ring spring and causing the outer ring of the diversion ring to rotate. This causes the square hole to separate from the sub-bag tube, and then the square hole coincides with the inlet of the mother bag tube, allowing the liquid to flow directly into the mother drainage bag. By pulling the limiting plate, the limiting insert plate is locked between the flow control box and the inner diversion plate, which can fix the position of the square hole and control the direction of liquid discharge.

[0006] Preferably, both the drainage mother bag and the drainage daughter bag are fixedly connected to a connection port on one side, and a connecting pipe connects the two connection ports. A one-way cylinder is fixedly connected to the inner side of the connecting pipe. A flow passage hole, a sealing hole, and a liquid inlet hole are opened on the inner side of the one-way cylinder. A limit hole is opened on the inner side of the one-way cylinder. The flow passage hole communicates with the sealing hole, the sealing hole communicates with the liquid inlet hole, and the flow passage hole communicates with the limit hole. A fixed inner ring is slidably engaged with the inner side of the flow passage hole. A connecting support is fixedly connected inside the fixed inner ring. A fixed inner column is fixedly connected inside the connecting support. A sealing ball is fixedly connected to one end of the fixed inner column. The sealing ball is slidably engaged with the inner side of the sealing hole. A limit mounting ring is fixedly connected to one end of the fixed inner ring. The limit mounting ring is slidably engaged with the inner side of the limit hole. A one-way spring is movably sleeved on the outer side of the fixed inner ring. The spring is installed inside the limiting hole. The outer side of the drainage tube is movably engaged with a winding box. The inner side of the winding box is rotatably connected to a winding column. The outer side of the winding column is fixedly connected to two opposing rotating plates. The drainage tube is movably engaged with the inner side of the rotating plates. The inner winding column is fixedly connected to the inside of the winding column. The inner winding column is rotatably connected to the winding box. The top of the inner winding column is fixedly connected to a winding rotating plate. In use: when the drainage sub-bag is full, it will be guided to the drainage mother bag through the connecting tube. By squeezing the sealing ball, the one-way spring is compressed, causing the sealing ball to disengage from the sealing hole and enter the flow hole. The liquid is discharged into the drainage mother bag through the inlet hole and then through the flow hole. The flow control box is controlled so that both sides are not connected. Squeezing the drainage sub-bag can squeeze all the liquid into the interior of the drainage mother bag. By setting the winding box and rotating the winding rotating plate, the winding column is rotated, causing the drainage tube to circle along the inner groove of the rotating plate. The length of the drainage tube can be adjusted for convenient use.

[0007] This invention provides an improved mother-daughter drainage bag with a plastic drainage valve, which has the following improvements and advantages compared with the prior art: Firstly, the present invention describes a mother-daughter drainage bag with a plastic drainage valve. One end of the drainage tube is used for drainage, allowing liquid to enter the interior of the control box through the drainage tube. When the liquid flow rate is low, the liquid enters the interior of the control box through the drainage tube and flows to the daughter bag tube through the square hole of the outer ring of the diversion, allowing the liquid to flow into the interior of the drainage daughter bag. When the liquid flow rate is high, the daughter bag tube is thinner than the drainage tube, which will push the extrusion plate to rotate, extruding the ring spring and causing the outer ring of the diversion to rotate, causing the square hole to separate from the daughter bag tube. Then, the square hole coincides with the inlet of the mother bag tube, allowing the liquid to be discharged directly into the drainage mother bag. By pulling the limiting plate, the limiting insert plate is locked between the control box and the inner plate of the diversion, which can fix the position of the square hole and control the direction of liquid discharge. Secondly, the present invention provides a mother-drainage bag with a plastic drainage valve. When the daughter drainage bag is full, it will guide the liquid to the mother drainage bag through the connecting pipe. By squeezing the sealing ball, the one-way spring is compressed, causing the sealing ball to disengage from the sealing hole and enter the flow hole. The liquid is then discharged into the mother drainage bag through the inlet hole and then through the flow hole. The flow control box is controlled to be closed on both sides. Squeezing the daughter drainage bag can force all the liquid into the interior of the mother drainage bag. By setting a winding box and rotating the winding plate, the winding column is driven to rotate, causing the drainage tube to circle along the inner groove of the rotating plate. The length of the drainage tube can be adjusted for convenient use. In summary, the present invention discloses a mother-daughter drainage bag with plastic drainage valves. This mother-daughter drainage bag allows for precise metering of small amounts of drainage fluid in the daughter bag and large-capacity storage of accumulated fluid in the mother bag. With the addition of dual plastic drainage valves, the fluid in the daughter bag can be flexibly diverted to the mother bag, and the mother bag can be emptied independently. This provides accurate drainage data for clinical use, adapts to different drainage volume scenarios, reduces tubing operations, lowers the risk of infection, and improves nursing efficiency.

[0010] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. 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.

[0011] This invention provides an improved mother-daughter drainage bag with a plastic drainage valve. The technical solution of this invention is as follows: like Figures 1-7As shown, a mother-drainage bag system with a plastic drainage valve includes a mother drainage bag 1 and a daughter drainage bag 2. One end of the mother drainage bag 1 is fixedly connected to a mother bag opening 6, and the other end is fixedly connected to a drain outlet 5. A mother bag tube 21 is connected inside the mother bag opening 6. One end of the daughter drainage bag 2 is fixedly connected to a daughter bag opening 10, and a daughter bag tube 22 is connected inside the daughter bag opening 10. A flow control box 3 is fixedly connected to one end of the mother bag tube 21 and the daughter bag tube 22. A drainage tube 23 is fixedly connected to the outside of the flow control box 3, and a fixing side ring 25 is fixedly connected to the inside of the flow control box 3. A diverter inner disc 24 is rotatably connected to the side, and the diverter inner disc 24 is rotatably connected to the fixed side ring 25. A compression plate 29 is fixedly connected to the outer side of the diverter inner disc 24. A diverter outer ring 28 is fixedly connected to the side of the compression plate 29 away from the diverter inner disc 24. A square hole is opened on the inner side of the diverter outer ring 28. An annular slide post 26 is slidably engaged inside the fixed side ring 25. One end of the annular slide post 26 is fixedly connected to the compression plate 29. An annular spring 27 is movably sleeved on the outer side of the annular slide post 26. A fixed insert post 30 is movably engaged on the inner side of the diverter inner disc 24. One end of the fixed insert post 30 is fixed. A limiting pull plate 31 is connected, and a limiting insert plate 32 is fixedly connected to the end of the fixed insert 30 away from the limiting pull plate 31. The limiting insert plate 32 is movably engaged with the bottom of the flow control box 3. The bottom of the inner diverter plate 24 is provided with a slot that matches the limiting insert plate 32. In use: one end of the diversion tube 23 is used for diversion, allowing the liquid to enter the interior of the flow control box 3 through the diversion tube 23. When the liquid flow rate is low, the liquid enters the interior of the flow control box 3 through the diversion tube 23 and flows through the square hole of the outer diverter ring 28 to the sub-bag tube 22, allowing the liquid to flow into the interior of the diversion sub-bag 2. When the liquid flow rate is high... When the flow is large, the sub-bag tube 22 is thinner than the drainage tube 23, which will push the squeezing plate 29 to rotate, squeezing the annular spring 27, causing the outer diversion ring 28 to rotate, so that the square hole is separated from the sub-bag tube 22. Then the square hole coincides with the inlet of the mother bag tube 21, allowing the liquid to be discharged directly into the drainage mother bag 1. By pulling the limiting plate 31, the limiting insert plate 32 is locked between the flow control box 3 and the inner diversion plate 24, which can fix the position of the square hole and control the direction of liquid discharge. All kinds of tubes are set independently according to the liquid to be drained, and the shape and size of the mother and daughter bags can be set according to the needs.

[0012] Furthermore, a connection port 7 is fixedly connected to one side of both the drainage mother bag 1 and the drainage daughter bag 2. A connecting pipe 8 connects the two connection ports 7. A one-way cylinder 9 is fixedly connected to the inner side of the connecting pipe 8. A flow passage hole 19, a sealing hole 18, and a liquid inlet hole 17 are opened on the inner side of the one-way cylinder 9. A limit hole 20 is opened on the inner side of the one-way cylinder 9. The flow passage hole 19 communicates with the sealing hole 18, the sealing hole 18 communicates with the liquid inlet hole 17, and the flow passage hole 19 communicates with the limit hole 20. A fixed inner ring 11 is slidably engaged with the inner side of hole 19. A connecting support 12 is fixedly connected inside the fixed inner ring 11. A fixed inner column 13 is fixedly connected inside the connecting support 12. A sealing ball 14 is fixedly connected to one end of the fixed inner column 13. The sealing ball 14 is slidably engaged with the inner side of the sealing hole 18. A limit mounting ring 15 is fixedly connected to one end of the fixed inner ring 11. The limit mounting ring 15 is slidably engaged with the inside of the limit hole 20. A one-way spring 16 is movably sleeved on the outer side of the fixed inner ring 11. The one-way spring 16 is installed on... Inside the limiting hole 20, the outer side of the drainage tube 23 is movably engaged with the winding box 4. The inner side of the winding box 4 is rotatably connected to the winding post 33. Two opposing rotating plates 35 are fixedly connected to the outer side of the winding post 33. The drainage tube 23 is movably engaged with the inner side of the rotating plate 35. An inner winding post 34 is fixedly connected inside the winding post 33. The inner winding post 34 is rotatably connected to the winding box 4. A winding rotating plate 36 is fixedly connected to the top of the inner winding post 34. In use: when the drainage sub-bag 2 overflows, it will flow into the drainage mother bag through the connecting pipe 8. 1. Flow guidance: By squeezing the sealing ball 14, the one-way spring 16 is compressed, causing the sealing ball 14 to disengage from the sealing hole 18 and enter the flow passage 19. The liquid is then discharged through the inlet hole 17 and the flow passage 19 to the main drainage bag 1. The flow control box 3 is controlled to be closed on both sides. Squeezing the drainage sub-bag 2 can squeeze all the liquid into the interior of the main drainage bag 1. By setting the winding box 4 and rotating the winding plate 36, the winding column 33 is driven to rotate, causing the drainage tube 23 to circle along the inner groove of the rotating plate 35. The length of the drainage tube 23 can be adjusted for convenient use.

[0013] Working principle: During use: One end of the drainage tube 23 is used for drainage, allowing liquid to enter the control box 3 through the drainage tube 23. When the liquid flow rate is low, the liquid enters the control box 3 through the drainage tube 23 and flows through the square hole of the outer diversion ring 28 to the daughter bag tube 22, allowing the liquid to flow into the drainage daughter bag 2. When the liquid flow rate is high, the daughter bag tube 22 is thinner than the drainage tube 23, which pushes the squeezing plate 29 to rotate, squeezing the annular spring 27, causing the outer diversion ring 28 to rotate, causing the square hole to disengage from the daughter bag tube 22. Then, the square hole coincides with the inlet of the mother bag tube 21, allowing the liquid to flow directly into the drainage mother bag 1. By pulling the limiting pull plate 31, the limiting insert plate 32 is locked in the control box. Between the 3 and the inner diversion plate 24, the position of the square hole can be fixed to control the direction of liquid discharge. When the drainage sub-bag 2 is full, it will be guided to the drainage mother bag 1 through the connecting pipe 8. By squeezing the sealing ball 14, the one-way spring 16 is compressed, causing the sealing ball 14 to disengage from the sealing hole 18 and enter the flow hole 19, so that the liquid is discharged to the drainage mother bag 1 through the liquid inlet hole 17 and then through the flow hole 19. The flow control box 3 is controlled to be closed on both sides. Squeezing the drainage sub-bag 2 can squeeze all the liquid into the interior of the drainage mother bag 1. By setting the winding box 4, rotating the winding plate 36 drives the winding column 33 to rotate, so that the drainage tube 23 is wrapped around the inner groove of the rotating plate 35. The length of the drainage tube 23 can be adjusted for easy use.
