[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0025] Please see Figs. 1-3 As shown, this application provides a drainage tube unblocking clamp, which includes a first clamping member 1, a second clamping member 2, an adjusting screw 3, and a roller assembly 4. The first clamping member 1 and the second clamping member 2 are disposed opposite to each other. The roller assembly 4 includes a first roller 41 rotatably mounted on the first clamping member 1 in a first horizontal direction and a second roller 42 rotatably mounted on the second clamping member 2 in a first horizontal direction, and a clamping gap for clamping the drainage tube 100 is formed between the first roller 41 and the second roller 42.
[0026] The adjusting screw 3 is threadedly connected to one of the first clamping member 1 and the second clamping member 2 to adjust the distance between the first clamping member 1 and the second clamping member 2, thereby changing the width of the clamping gap.
[0027] This application allows for flexible adjustment of the clamping gap width between the first roller 41 and the second roller 42 by rotating the adjusting screw 3, thereby achieving effective clamping and squeezing of drainage tubes 100 of different diameters. After clamping and squeezing the drainage tube 100, the first roller 41 and the second roller 42 are pushed to roll along the length of the drainage tube 100, which can effectively unclog the drainage tube 100. This improves the unclogging efficiency while maximizing the safety performance of the drainage tube 100.
[0028] Specifically, the first clamping member 1 consists of a first body 11 and a first mounting rod 12 extending outward from its front end, and the second clamping member 2 consists of a second body 21 and a second mounting rod 22 extending outward from its front end. Both the first mounting rod 12 and the second mounting rod 22 extend along a first horizontal direction. The first body 11 has a through hole 5, and the second body 21 has a threaded hole 6 coaxial with the through hole 5. The first roller 41 and the second roller 42 are respectively sleeved on the first mounting rod 12 and the second mounting rod 22 and can rotate freely. In this way, when unblocking the drainage tube 100, the rollers can rotate flexibly with the movement of the drainage tube 100, reducing the frictional resistance on the drainage tube 100 and avoiding damage to the drainage tube 100 due to forced dragging.
[0029] The adjusting screw 3 includes a screw portion 31 and a pressure head 32 located at one end. The screw portion 31 passes through the through hole 5 of the first clamping member 1 and is threadedly engaged with the threaded hole 6 of the second clamping member 2. The first clamping member 1 is movably connected to the screw portion 31. The pressure head 32 abuts against the surface of the first clamping member 1 facing away from the second clamping member 2. The outer diameter of the pressure head 32 is larger than the diameter of the mounting hole. The design of the pressure head 32 conforms to ergonomic principles, making it convenient for operators to tighten. By rotating the adjusting screw 3, the distance between the first clamping member 1 and the second clamping member 2 can be precisely adjusted. This threaded adjustment method has high precision and can make fine adjustments according to the actual diameter of the drainage tube 100, ensuring that the first roller 41 and the second roller 42 can squeeze the drainage tube 100 without over-squeezing it. For example, when dealing with drainage tubes 100 that have thin walls or are made of special materials, precise adjustment can effectively prevent the drainage tube 100 from deforming or breaking due to excessive clamping force, thus ensuring the normal use of the drainage tube 100 and medical safety.
[0030] The outer periphery of the first roller 41 and the second roller 42 are respectively provided with multiple axially distributed protrusion groups 7. Each protrusion group 7 consists of several circumferentially arranged protrusions 71, and the protrusion groups 7 on the first roller 41 and the protrusion groups 7 on the second roller 42 are staggered along the roller axis (i.e., the first horizontal direction). When clearing the drainage tube 100, these protrusions can penetrate into the texture and gaps of the drainage tube 100 wall, and have a strong scraping and breaking ability for blockages such as blood clots and fibrin attached to the tube wall. The staggered arrangement of the protrusion groups 7 further increases the cleaning effect on blockages, making the clearing more thorough. Compared with traditional smooth rollers, this roller with a protruding structure can significantly improve the clearing efficiency without increasing the pressure on the drainage tube 100 wall, effectively solving the problem of drainage tube 100 blockage, reducing various complications caused by drainage tube 100 blockage, and improving the quality of medical care.
[0031] The drainage tube unblocking clamp may include multiple roller sets 4, which are spaced apart along a second horizontal direction perpendicular to the first horizontal direction. Multiple sets of rollers can simultaneously unblock multiple sections of the drainage tube 100, significantly shortening the unblocking time. For long or multi-blocked drainage tubes 100, the synergistic effect of multiple sets of rollers can complete the comprehensive unblocking work in one go, eliminating the need for repeated operations and improving work efficiency. Moreover, multiple sets of rollers can evenly distribute the force on the drainage tube 100 during unblocking, avoiding damage to the drainage tube 100 caused by excessive localized force, further ensuring the safety performance of the drainage tube 100.
[0032] The drainage tube unblocking clamp also includes baffles 8 respectively disposed at both ends of the clamping gap. The baffles 8 are mounted on one of the first mounting rod 12 and the second mounting rod 22. The function of the baffles 8 is to limit the drainage tube 100 during the unblocking process and prevent the drainage tube 100 from sliding out from both ends of the clamping gap. In actual operation, especially when dealing with some relatively smooth or curved drainage tubes 100, the baffles 8 can effectively fix the position of the drainage tube 100, ensuring that the first roller 41 and the second roller 42 can continuously and stably perform unblocking operations on the drainage tube 100, avoiding unblocking failure or damage to surrounding tissues due to displacement of the drainage tube 100, and improving the reliability and safety of the unblocking operation.
[0033] The drainage tube unblocking clamp also includes an elastic element 9, which is disposed between the first body 11 and the second body 21, with one end contacting the first body 11 and the other end contacting the second body 21. The presence of the elastic element 9 provides a certain tension to the first roller 41 and the second roller 42. When the adjusting screw 3 gradually withdraws from the threaded hole 6, the spring rebounds to drive the first clamping member 1 and the second clamping member 2, the first roller 41 and the second roller 42 away from each other, releasing the clamp on the drainage tube 100.
[0034] In one possible embodiment, the elastic element 9 is specifically a spring that surrounds the adjusting screw 3, with one end extending into the through hole 5 and abutting against the stepped surface located within the through hole 5, and the other end abutting against the surface of the first body 11 opposite to the second body 21.
[0035] The first body 11 is provided with a guide portion 13 extending toward the second body 21, and the second body 21 is provided with a matching guide groove 23. The second body 21 slides along the guide portion 13 via the guide groove 23. The existence of the guide structure greatly improves the accuracy and stability of the relative movement of the first clamping member 1 and the second clamping member 2. When adjusting the clamping gap width, it can effectively prevent skewing or misalignment caused by uneven force, ensuring that the first roller 41 and the second roller 42 can always clamp the drainage tube 100 evenly, thereby performing a comprehensive and stable unblocking operation on the drainage tube 100, improving the unblocking effect and extending the service life of the drainage tube 100.
[0036] In one possible embodiment, the guide portion 13 is an irregular ring-shaped structure.
[0037] The second clamping member 2 also includes a handle 24 extending outward from the rear end of the second body 21. The handle 24 is designed in accordance with ergonomic principles, making it convenient for operators to grip and apply force. When unblocking the drainage tube 100, the operator can easily control the movement of the second clamping member 2 through the handle 24, allowing the drainage tube unblocking clamp to smoothly advance or retract along the length of the drainage tube 100, improving the convenience and accuracy of operation, reducing the labor intensity of the operator, and also reducing the risk of damage to the drainage tube 100 due to improper operation.
[0038] Instructions for use: When using the drainage tube unblocking clamp of this application, firstly, according to the diameter of the drainage tube 100, rotate the adjusting screw 3 to allow the first clamping member 1 and the second clamping member 2 to be spring-loaded until the clamping gap between the first roller 41 and the second roller 42 is slightly larger than the outer diameter of the drainage tube 100. Then, place the drainage tube 100 in the clamping gap between the first roller 41 and the second roller 42, and then rotate the adjusting screw 3 in the opposite direction to bring the first roller 41 and the second roller 42 closer together to compress the drainage tube 100 to a suitable thickness. Afterward, the operator holds the handle 24 of the second clamping member 2 and slowly moves the drainage tube unblocking clamp along the length of the drainage tube 100. At this time, the protrusions 7 on the first roller 41 and the second roller 42 will squeeze and scrape the wall of the drainage tube 100 to remove the blockage on the tube wall, thereby unblocking the drainage tube 100. During the dredging process, multiple sets of rollers work together to improve dredging efficiency, while baffle 8 can prevent the drainage pipe 100 from slipping, ensuring the smooth progress of the entire dredging process.
[0039] In summary, the drainage tube unblocking clamp in this application effectively solves the problem of drainage tube 100 blockage through the ingenious design and synergistic effect of its components. While improving unblocking efficiency, it maximizes the safety performance of drainage tube 100 and has broad clinical application prospects. It provides a reliable and efficient solution for unblocking drainage tube 100 in the medical field.
