Description

Technical Field

[0001] This application relates to the field of medical device technology, and more specifically, to a venous urinal. Background Technology

[0002] Hemodialysis is a crucial treatment for diseases such as kidney failure. It involves circulating blood outside the body and using a dialyzer to exchange substances, removing metabolic waste and maintaining electrolyte balance. During hemodialysis, the venous chamber, a key component of the hemodialysis tubing system, is primarily used to prevent air from entering the body, intercept blood clots, monitor venous pressure, and administer anticoagulants. However, existing venous chambers often face the problem of blood clot blockage, which not only affects dialysis effectiveness but can also lead to blood waste and increased burden on patients.

[0003] Traditional intravenous infusions often require replacing the entire intravenous tubing when dealing with thrombotic blockages. This not only increases medical costs for patients but can also lead to a series of complications, such as hypotension and hypovolemic shock. Furthermore, existing intravenous infusions present challenges in disassembly, assembly, and replacement, increasing the risk of blood leakage and air embolism, thus increasing the workload and infection risk for healthcare workers. While technologies employing detachable infusions or dual-filter systems have been developed to address thrombotic blockages in intravenous infusions, these still have limitations, such as complex operation and the potential for bacterial infection. Utility Model Content

[0004] This application provides a venous chamber that enables self-cleaning of the filter element to prevent thrombus blockage, effectively preventing thrombus blockage from affecting blood flow, improving blood filtration efficiency, ensuring smooth blood flow, reducing the risk of treatment interruption due to thrombus blockage, and improving the continuity, stability and safety of dialysis treatment.

[0030] In this application, "multiple" means two or more (including two).

[0031] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the vein pot provided in this application.

[0032] This application provides a venous infusion vessel, including an infusion vessel body 1, a filter element 2, and a cleaning device 3. The infusion vessel body 1 has an internal cavity, and is provided with a blood inlet 13 and a blood outlet 14, which communicate with the internal cavity. Optionally, the blood inlet 13 is located at the top of the infusion vessel body 1, and the blood outlet 14 is located at the bottom of the infusion vessel body 1.

[0033] The filter element 2 is disposed in the inner cavity and fixedly connected to the inner cavity. A filter channel 112 is formed inside the filter element 2, and the filter channel 112 is connected to the blood outlet 14. A blood channel 111 is formed between the filter element 2 and the body 1 of the vessel. The filter channel 112 is formed inside the filter element 2, and the filter channel 112 is connected to the blood outlet 14.

[0034] The cleaning device 3 includes a drive member 31 and a cleaning member 32. The cleaning member 32 is disposed on the outside of the filter element 2. The drive member 31 is directly or indirectly connected to the cleaning member 32. The drive member 31 provides a rotational driving force to the cleaning member 32 to drive the cleaning member 32 to rotate around the central axis of the filter element 2 and move along the outer periphery of the filter element 2, thereby removing the clogging material attached to the outer wall of the filter element 2.

[0035] During use, blood enters the vessel body 1 through the blood inlet 13, is filtered by the filter element 2, and flows out through the blood outlet 14. When the filter element 2 becomes clogged, the driving component 31 rotates the cleaning component 32 circumferentially along the outer side of the filter element 2 to clean it. When the blockage is severe, the cleaning component 32 ensures smooth blood flow, timely blood recovery, and effectively reduces blood waste. The entire venous vessel features a seamless design, reducing the risk of blood leakage.

[0036] This application provides a cleaning device 3 inside the dialysis vessel body 1, which can quickly clean the filter element 2 when thrombus blockage occurs, effectively preventing thrombus blockage from affecting blood flow, reducing the risk of treatment interruption due to thrombus blockage, and improving the continuity and stability of dialysis treatment.

[0037] In one specific embodiment, the kettle body 1 includes an end cap 12, a kettle body 11, and a sealing element. The kettle body 11 has a cylindrical structure with a hollow interior forming an inner cavity, forming a blood channel 111 between the kettle body 11 and the filter element 2. A blood inlet 13 is located at the top of the kettle body 1 to receive blood, and a blood outlet 14 is located at the bottom of the kettle body 1 to output filtered blood. The end cap 12 is sealed to the kettle body 11, making the entire kettle body 1 seamlessly connected to reduce the risk of blood leakage. The end cap 12 has a sealing element inside, which achieves a sealed connection between the drive element 31 and the end cap 12. This facilitates opening the kettle body 1, making it easier to replace the filter element 2 and clean the kettle body 11.

[0038] In addition, the body of the vessel 1 is also provided with a bypass port 15, which is connected to the blood channel 111 inside the body of the vessel 1. The bypass port 15 can be located at the top of the body of the vessel 1. The bypass port 15 can be used as a pressure monitoring interface or an anticoagulant injection interface. The bypass port 15 is connected to a pressure monitoring device or an anticoagulant injection device. The pressure monitoring device monitors venous pressure through the bypass port 15, and the anticoagulant injection device injects anticoagulant through the bypass port 15.

[0039] Furthermore, the filter element 2 is a cylindrical filter screen, installed vertically to ensure filtration efficiency. Optionally, the height of the filter element 2 is adapted to the height of the pot body 11. The upper end of the filter element 2 is fixedly connected to the bottom surface of the end cap 12, and the lower end of the filter element 2 is fixedly connected to the bottom wall of the inner cavity of the pot body 1. The interior of the filter element 2 forms a filtration channel 112. Blood enters the blood channel 111 inside the pot body 11 through the blood inlet 13, is filtered by the filter element 2, and finally flows out through the blood outlet 14 via the filtration channel 112.

[0040] In this embodiment, a cylindrical filter screen with interconnected top and bottom is adopted, which significantly increases the filtration area. Compared with traditional filter screens, it prolongs the time before clogging occurs, improves blood filtration efficiency, and ensures smooth blood flow.

[0041] In one specific embodiment, the filter element 2 is made of a brittle polymer material, specifically one or more of brittle polymethyl methacrylate, brittle polyvinyl chloride, or brittle polypropylene. Due to its brittleness and lack of powder generation, it ensures the filtration effect while avoiding the formation of powder and other impurities.

[0042] Optionally, the filter screen has a mesh size of 180 micrometers to 500 micrometers, which can effectively intercept blood clots and particles.

[0043] In one specific embodiment, the driving member 31 can be a T-shaped rod with a T-shaped structure. The upper part of the driving member 31 extends from the end cap 12 of the kettle body 1, and the T-shaped end of the T-shaped rod is exposed outside the kettle body 1. The top of the filter element 2 is fixedly connected to the support rod 33. The driving member 31 is connected to the cleaning element 32 through the support rod 33, thereby driving the cleaning element 32 to move.

[0044] In one specific embodiment, the cleaning component 32 includes a brush head base and multiple bristle tufts, with the bottom of the drive component 31 fixedly connected to the brush head base. The brush head base has bristle tufts distributed on it. Both the brush head base and the bristle tufts can be made of corrosion-resistant materials. The bristle tufts are fixed to the brush head base at predetermined intervals and arrangements, and can be distributed across the entire contour surface of the brush head base. Specifically, the bristle tufts can be concentrated on the inner side of the brush head base facing the filter element 2, or they can be distributed simultaneously on both the inner and outer sides of the filter element 2. The bristle tufts can be separately connected to the brush head base, for example, by binding, wrapping, bonding, or using locking devices, or by integral molding, etc., but the secure installation of the bristle tufts must be ensured to prevent them from falling off when cleaning the surface of the filter element 2. In this way, when blockage occurs, the filter element 2 can be cleaned, ensuring smooth blood return and reducing blood waste.

[0045] Optionally, the brush head holder is an arc-shaped brush head holder, for example, it can be semi-circular, quarter-circular, or three-quarter-circular, etc. To avoid interference between the brush head holder and the filter element 2 when rotating, the curvature of the inner arc surface of the brush head holder is the same as the curvature of the outer circumference surface of the filter element 2.

[0046] To ensure that the cleaning component 32 moves precisely around the outer circumference of the filter component 2, a circular track can be set on the inner bottom surface of the pot body 11. The bottom of the brush head seat is adapted to the circular track, and the two are slidably connected. The circular track provides guidance for the cleaning component 32, and the cleaning component 32 moves precisely along the circular track, thereby ensuring the cleaning effect.

[0047] In addition, anti-slip textures can be provided on the outer surface of the pot body 11 to increase the friction between the pot body 11 and the hand, prevent slipping, and improve the comfort of holding.

[0048] The above provides a detailed description of the venous catheter provided in this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of this application.
