Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary devices, and more specifically, to an auxiliary device for preventing obstruction of tumor drainage in the thoracic cavity. Background Technology

[0002] Following thoracic surgery in cancer patients, chest drainage tubes are crucial medical devices for draining pleural effusion and pneumothorax to promote lung re-expansion and prevent infection. However, existing chest drainage tubes present numerous problems in practical application. Because pleural effusions in cancer patients often contain large amounts of blood clots, fibrin, or necrotic tumor tissue, these substances easily adhere to the tube walls, leading to blockage and impaired drainage. This not only affects the patient's recovery process and increases their suffering but can also trigger a series of complications, such as pleural infection and pneumothorax.

[0003] To address the problem of drainage tube blockage, some existing technologies employ electronic sensors or complex mechanical structures. While electronic sensors can monitor drainage tube blockage in a timely manner, they are costly and require a relatively high level of expertise from both the user and the operating environment, and are also subject to the risk of electronic component failure. Complex mechanical structures, on the other hand, are often difficult to maintain, increasing the workload and operating costs for medical staff, thus hindering their widespread clinical application.

[0004] How to invent an auxiliary device for preventing obstruction of thoracic drainage of tumors to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an anti-blockage thoracic drainage auxiliary device for tumors, which aims to improve the problem that existing thoracic drainage tubes are prone to blockage during drainage, while some anti-blockage drainage tubes with electronic sensors and mechanical structures increase the cost of use and maintenance.

[0006] This utility model is implemented as follows: A tumor pleural drainage auxiliary device for preventing blockage includes a drainage tube, which comprises a liquid inlet section and an anti-blockage section. The liquid inlet section and the anti-blockage section are connected at one end. A spiral elastic sheet is provided inside the anti-blockage section. One end of the spiral elastic sheet is fixedly connected to the inner wall of the anti-blockage section. A filter structure is also provided inside the anti-blockage section on the side of the spiral elastic sheet away from the liquid inlet section. An external unblocking structure corresponding to the filter structure is also provided on the outer wall of one side of the anti-blockage section.

[0007] In a preferred embodiment of this invention, the edge of the spiral elastic sheet facing the liquid inlet section is configured as a cutting edge.

[0008] In a preferred embodiment of this utility model, the filter structure is a filter ring, the filter ring includes a ring body, a filter screen is disposed between the inner walls of the ring body, and a clamp corresponding to and limiting the anti-clogging section is sleeved on the outside of the ring body.

[0009] In a preferred embodiment of this utility model, the external unblocking structure includes a connecting side pipe integrally connected to the outer wall of one side of the anti-blocking section, and a balloon is connected to the other end of the connecting side pipe.

[0010] In a preferred embodiment of this utility model, the connecting side tube extends obliquely upward toward the filter structure, with one end in the axial direction facing the center point of the filter structure.

[0011] In a preferred embodiment of this utility model, the inlet section, the anti-blocking section, the connecting side tube, and the balloon are all made of transparent material.

[0012] In a preferred embodiment of this utility model, the liquid inlet section and the anti-clogging section are detachably connected at one end by a threaded connector. The threaded connector includes a male threaded connector and a female threaded connector. Both ends of the anti-clogging section are provided with female threaded connectors, and the end connecting the liquid inlet section and the anti-clogging section is provided with a male threaded connector.

[0013] The beneficial effects of this utility model are as follows: The anti-blockage thoracic drainage aid for tumors, obtained through the above design, features a spiral elastic sheet in the anti-blockage section of the drainage tube. This sheet automatically cuts large impurities as the fluid flows, and the filtration structure further intercepts remaining impurities, ensuring smooth drainage.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: an anti-blocking thoracic cavity drainage auxiliary device for tumors, including a drainage tube, which includes two parts: an inlet section 1 and an anti-blocking section 2. The inlet section 1 and the anti-blocking section 2 are connected at one end. A spiral elastic sheet 201 is provided inside the anti-blocking section 2. One end of the spiral elastic sheet 201 is fixedly connected to the inner wall of the anti-blocking section 2. A filter structure is also provided inside the anti-blocking section 2 on the side of the spiral elastic sheet 201 away from the inlet section 1. An external unblocking structure corresponding to the filter structure is also provided on the outer wall of one side of the anti-blocking section 2.

[0022] It should be noted that the spiral elastic sheet 201 can be fixed using micro-hinges or elastic clips to form a "cantilever beam" structure. Combining drainage and anti-clogging functions, the spiral elastic sheet 201 can cut large impurities in the accumulated liquid, the filtration structure further intercepts impurities, and the external unblocking structure can promptly solve the problem of clogging in the filtration structure, improving the efficiency and reliability of drainage and reducing the situation of poor drainage or frequent replacement of drainage tubes due to clogging.

[0023] Please see Figures 2 to 4 The edge of the spiral elastic sheet 201 facing the liquid inlet section 1 is set as a cutting edge 202.

[0024] The spiral elastic plate 201 has a cutting edge 202 on the side facing the inlet section 1. The cutting edge 202 is single-edged with a cutting angle of 60°-80°. The use of a non-sharp blade avoids damage to the anti-clogging section 2 wall or the formation of sharp burrs during cutting. The spiral elastic plate 201 is made of medical-grade stainless steel or nickel-titanium alloy, etc., elastic metal materials. Under the impact and friction generated by the flow of accumulated fluid, the spiral shape decomposes the impact force into a component force along the spiral direction, driving the spiral elastic plate 201 to rotate around the central axis of the drainage tube. The cutting edge 202 then cuts large impurities. This improves the cutting efficiency of the spiral elastic plate 201, effectively breaking up blood clots, fibrin clusters, and other blockages, while protecting the drainage tube wall and extending the service life of the drainage tube.

[0025] Furthermore, the filter structure is a filter ring 203, which includes a ring body, a filter screen is provided between the inner walls of the ring body, and a clamp 204 corresponding to and limiting the anti-clogging section 2 is sleeved on the outside of the ring body.

[0026] The filter structure consists of a filter ring 203, which includes a ring body with a filter screen disposed between the inner walls of the ring. A clamp 204 is fitted onto the outside of the anti-clogging section 2, corresponding to the ring body and securing the filter ring 203 within the anti-clogging section 2. The clamp 204 can be detachable, for example, connected by bolts or clips, allowing for easy opening of the clamp 204 to clean or replace the filter ring 203 when needed. This detachable filter structure design facilitates maintenance and upkeep, promptly removing accumulated impurities from the filter ring 203, ensuring filtration efficiency, reducing operating costs, and avoiding the need to replace the entire drainage pipe due to filter structure clogging.

[0027] Furthermore, the external unblocking structure includes a connecting side pipe 205 integrally connected to the outer wall of one side of the anti-blocking section 2, and a balloon 206 connected to the other end of the connecting side pipe 205.

[0028] The external drainage structure consists of a connecting side tube 205 and a balloon 206. The connecting side tube 205 is integrally connected to the outer wall of one side of the anti-blocking section 2, and its other end is connected to the balloon 206. The balloon 206 is made of medical-grade silicone with a thickness of 0.3-0.5mm, an elastic recovery rate of ≥90%, and a capacity of 10-15mL. When drainage is required, the balloon 206 is repeatedly squeezed to create negative pressure inside the anti-blocking section 2, driving liquid in and out of the balloon 206, thereby flushing the filtration structure. Drainage can be performed without disassembling the drainage tube, reducing the risk of infection and improving the safety and convenience of the drainage process.

[0029] Furthermore, the connecting side tube 205 extends obliquely upward toward the filter structure, with one end in the axial direction facing the center point of the filter structure.

[0030] The connecting side tube 205 extends obliquely upwards towards the filter structure, with one end pointing towards the center of the filter structure. This allows the liquid to be more concentrated and directed towards the critical parts of the filter structure when the balloon 206 is squeezed, enhancing the impact force on clogging impurities. This improves the working efficiency of the external unblocking structure, more effectively removing blockages from the filter structure and ensuring the unobstructed flow of the drainage tube.

[0031] Furthermore, the inlet section 1, the anti-blocking section 2, the connecting side tube 205, and the balloon 206 are all made of transparent material.

[0032] The inlet section 1, anti-blockage section 2, connecting side tube 205, and balloon 206 are all made of transparent medical-grade plastic or silicone. Medical staff can directly observe the internal structure of these components to promptly detect any blockages, abnormal fluid color, or other problems. This improves the visibility of the drainage process, helping medical staff to take timely and appropriate measures to ensure patient safety and drainage effectiveness.

[0033] Furthermore, the inlet section 1 and the anti-clogging section 2 are detachably connected at one end by a threaded connector 3. The threaded connector 3 includes a threaded male connector 301 and a threaded female connector 302. Both ends of the anti-clogging section 2 are provided with threaded female connectors 302, and the end connecting the inlet section 1 and the anti-clogging section 2 is provided with a threaded male connector 301.

[0034] The inlet section 1 and the anti-clogging section 2 are detachably connected at one end via a threaded connector 3, which includes a threaded male connector 301 and a threaded female connector 302. Both ends of the anti-clogging section 2 are equipped with threaded female connectors 302, and the end connecting the inlet section 1 and the anti-clogging section 2 is equipped with a threaded male connector 301. The connection and disconnection of the inlet section 1 and the anti-clogging section 2 are achieved through the engagement of the threads. This detachable connection method facilitates the assembly, disassembly, and maintenance of the drainage tube, reducing operating costs. Furthermore, the inlet section 1 or the anti-clogging section 2 can be replaced as needed under different circumstances, improving the applicability of the drainage tube.

[0035] Working Principle: Pleural effusion flows into the anti-blockage section 2 through the inlet section 1. The impact and friction generated by the fluid flow act on the spiral elastic sheet 201. Because the spiral elastic sheet 201 is spiral-shaped, it decomposes the impact force into components along the spiral direction, driving it to rotate around the central axis of the drainage tube. The cutting edge 202 on the side facing the inlet section 1 cuts large impurities in the effusion, such as blood clots and fibrin clusters, preventing large impurities from directly clogging the drainage tube. At the same time, the non-sharp blade design prevents damage to the wall of the anti-blockage section 2. The cut impurities continue to flow with the effusion to the filtration structure, namely the filter ring 203. The filter screen between the inner walls of the ring will intercept the remaining impurities. If the filter ring 203 becomes blocked, medical staff can repeatedly squeeze the balloon 206 to create negative pressure inside the anti-blockage section 2, driving the fluid in and out of the balloon 206. The fluid can flush the filtration structure and clear the blockage.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
