Description

Technical Field

[0001] This utility model relates to the field of abdominal drainage tube technology, and more specifically, to an adjustable flow rate abdominal drainage tube. Background Technology

[0002] An adjustable-flow-rate abdominal drainage tube is a medical device designed to drain substances such as fluid or blood from a patient's abdominal cavity. This device is essential for postoperative care, management of acute or chronic ascites, and other situations requiring continuous or intermittent abdominal drainage.

[0003] In the prior art, for example, Chinese Patent Publication No. CN221692201U discloses an abdominal drainage tube for preventing blockage, including a drainage tube, a limit interface threaded to the front end of the drainage tube, a connecting interface threaded to the tail end of the drainage tube, an input hose fixedly installed at the input end of the connecting interface, an input seat fixedly installed at the input end of the input hose, a through tube fixedly installed at both the front and tail ends of the inner wall of the drainage tube, a separator mesh fixedly installed on the inner wall of the through tube, and a storage frame threadedly connected to the inner walls of both the limit interface and the connecting interface. By rotating the valve, if the output structure at the limit interface is still blocked, the drainage can be carried out by rotating the valve and using the diversion tube instead of the output hose. With the obstruction filtration of the internal filter screen, sieve, and separator mesh, the unobstructed flow of the device during drainage can be ensured as much as possible, and the impact of blockage can be reduced.

[0004] While existing technologies can achieve the effect of preventing blockage during drainage, they cannot control the flow rate of the drainage fluid. During the drainage process, medical staff cannot constantly monitor the patient's drainage status. Even minor movements such as turning over can cause the drainage fluid to flow out rapidly, and backflow of the drainage fluid may also occur. In view of this, we propose an adjustable flow rate abdominal drainage tube. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable flow rate abdominal drainage tube to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides an adjustable flow rate abdominal drainage tube, including a speed control device. A limiting plate is fixedly connected to the side of the speed control device. A fixing frame is fixedly connected to the end of the inner cavity of the speed control device near the limiting plate. A limiting rod is movably connected to the inner cavity of the fixing frame. A spring is movably connected to the surface of the limiting rod. A movable plug is fixedly connected to the end of the limiting rod away from the fixing frame. A connecting seat is movably connected to the side of the movable plug away from the limiting rod. The surface of the connecting seat near the movable plug is fixedly connected to the inner cavity of the speed control device away from the limiting plate. The end of the spring near the limiting plate is fixedly connected to the fixing frame, and the end of the spring away from the fixing frame is fixedly connected to the side of the movable plug.

[0007] As a further improvement to this technical solution, an input pipe is fixedly connected to the side of the limiting plate away from the speed control device, and an anti-blocking device is fixedly connected to the end of the input pipe away from the limiting plate. A flow divider is fixedly connected to the inner cavity of the anti-blocking device, and flow divider holes are provided on both sides of the flow divider.

[0008] As a further improvement to this technical solution, a control board is movably connected to the surface of the diverter, and a rotary valve is fixedly connected to the end of the control board away from the input pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This adjustable-flow-rate abdominal drainage tube precisely controls the flow rate of the drainage fluid through the interaction of a spring and a movable plug in the speed control device, avoiding complications caused by excessively fast or slow flow rates. The anti-clogging device, with its diverter, filter, and control panel, effectively prevents blockages and improves drainage reliability.

[0021] Furthermore, in the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0022] Please see Figures 1-4As shown, this utility model provides an adjustable flow rate abdominal drainage tube, including a speed control device 1. A limiting plate 16 is fixedly connected to the side of the speed control device 1. A fixing frame 11 is fixedly connected to the end of the inner cavity of the speed control device 1 near the limiting plate 16. A limiting rod 12 is movably connected to the inner cavity of the fixing frame 11. A spring 13 is movably connected to the surface of the limiting rod 12. A movable plug 14 is fixedly connected to the end of the limiting rod 12 away from the fixing frame 11. A connecting seat 15 is movably connected to the side of the movable plug 14 away from the limiting rod 12. The connecting seat 15 is close to the movable plug 14. One end of the surface of the spring 13 is fixedly connected to the inner cavity of the end of the speed control device 1 away from the limiting plate 16. The end of the spring 13 near the limiting plate 16 is fixedly connected to the fixed frame 11, and the end of the spring 13 away from the fixed frame 11 is fixedly connected to the side of the movable plug 14. When the drainage fluid pressure is too high, the movable plug 14 will be pushed to compress the spring 13, thereby reducing the flow rate and preventing adverse consequences caused by overpressure. When the drainage fluid pressure decreases, the elastic force of the spring 13 will push the movable plug 14 back to its original position, closing or reducing the flow rate, ensuring the safety and effectiveness of the drainage process.

[0023] Please see Figures 1-3 As shown, in this embodiment, an input pipe 17 is fixedly connected to the side of the limiting plate 16 away from the speed control device 1, and an anti-blocking device 2 is fixedly connected to the end of the input pipe 17 away from the limiting plate 16. A diverter 24 is fixedly connected to the inner cavity of the anti-blocking device 2, and diverting holes 25 are provided on both sides of the diverter 24. Through the design of the diverter 24 and the diverting holes 25, the drainage liquid is evenly dispersed, reducing the risk of blockage caused by excessive local flow. The porous design increases the flow path of the liquid, improves the overall flowability, and ensures the smoothness of the drainage process.

[0024] Please see Figures 2-3 As shown, a control plate 26 is movably connected to the surface of the diverter 24. A rotary valve 27 is fixedly connected to the end of the control plate 26 away from the input pipe 17. A filter screen 23 is provided on the side of the anti-clogging device 2 near the rotary valve 27. The opening and closing degree of the diverter 24 can be manually adjusted through the control plate 26 and the rotary valve 27 to further control the flow rate and meet the needs of different patients and under different conditions. The filter screen 23 can filter out impurities in the drainage fluid, prevent clogging, and improve the safety and effectiveness of drainage.

[0025] Please see Figures 2-3 As shown, specifically, the top of the anti-clogging device 2 is provided with several sealing grooves 22, and the inner cavity of the sealing groove 22 is movably connected to the sealing plate 21. The design of the sealing groove 22 and the sealing plate 21 ensures the sealing performance of the anti-clogging device 2, prevents liquid leakage, and ensures the smooth progress of the drainage process. The sealing plate 21 can be removed to facilitate the cleaning of the filter screen 23, and facilitates daily maintenance and cleaning.

[0026] Please see Figure 1 As shown, in addition, several output pipes 18 are fixedly connected to the side of the anti-clogging device 2 away from the input pipe 17. The end of the output pipe 18 away from the anti-clogging device 2 is fixedly connected to the liquid storage bottle 19. The output pipe 18 draws out the treated drainage liquid and collects it into the liquid storage bottle 19 for easy observation and treatment.

[0027] In summary, the working principle of this solution is as follows:

[0028] When the drainage fluid enters the speed control device 1, it pushes the movable plug 14 towards the limiting plate 16. The movement of the movable plug 14 compresses the spring 13, and the elastic force of the spring 13 gradually increases. When the elastic force of the spring 13 and the pressure of the drainage fluid reach equilibrium, the position of the movable plug 14 stabilizes, thereby controlling the flow rate of the drainage fluid. When the pressure of the drainage fluid decreases, the elastic force of the spring 13 pushes the movable plug 14 back to its original position, closing or reducing the flow rate. The drainage fluid enters the anti-clogging device 2 through the input pipe 17. The diverter 24 disperses the drainage fluid and distributes it evenly through the diverter holes 25 to reduce the possibility of clogging. The filter screen 23 filters out impurities in the drainage fluid to prevent clogging. The control plate 26 and the rotary valve 27 can adjust the opening and closing degree of the diverter 24 as needed to further control the flow rate. The treated drainage fluid enters the storage bottle 19 through the output pipe 18, completing the drainage process.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
