Description

Technical Field

[0001] This utility model relates to the technical field of tumor treatment, specifically to an anti-entanglement device for oncology catheters. Background Technology

[0002] Like internal medicine, surgery, obstetrics and gynecology, and pediatrics, oncology is a secondary discipline of clinical medicine. It is divided into internal oncology, radiation oncology, and surgical oncology. Internal oncology mainly deals with the medical treatment of various benign and malignant tumors. In the process of tumor treatment, various catheters are needed to be inserted into the patient's body for procedures such as draining fluids and injecting medications. Therefore, patients treated in oncology usually have a lot of medical catheters at the same time. In order to facilitate the use of catheters and avoid them from being tangled and crossing over for a long time, which would affect the delivery of medications, anti-tangling devices are needed to manage them.

[0003] In response to this, Chinese patent number CN215505054U proposes an anti-tangling device for catheters in oncology, which can simultaneously organize multiple catheters, reduce the labor intensity of medical staff, save disassembly time, improve work efficiency, and promptly organize catheters to prevent tangling, facilitate fluid flow through the catheters, and reduce harm to patients.

[0004] During tumor treatment, the difficulty of treating tumors varies among different patients. Patients with more difficult treatments may require catheters to be inserted into various parts of their body. However, the above-mentioned technical solutions and existing catheter anti-entanglement devices do not have a directional adjustment function when sorting the catheters. After sorting the catheters, if the patient turns over or moves their body, the catheters inserted in different areas will still alternate and become entangled. In fact, the catheters may even be pulled due to insufficient length, affecting the delivery of medication. In response to this, this design proposes an anti-entanglement device for oncology catheters. Utility Model Content

[0005] The purpose of this invention is to provide an anti-entanglement device for oncology catheters to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model proposes an anti-entanglement device for oncology catheters, including a mounting base plate and an adjustment mechanism and an anti-detachment component mounted on the upper end of the mounting base plate;

[0007] The adjustment mechanism includes a first support bar rotatably mounted on one side of the mounting base plate, a second support bar rotatably mounted at one end of the first support bar, and conduit supports hinged at the lower edges of both sides of the second support bar. Multiple limiting brackets are equidistantly mounted on one side of each of the two conduit supports. Multiple connecting grooves are equidistantly opened on one side of each of the two conduit supports. Limiting grooves are opened on both sides of the inner wall of each connecting groove. Multiple connecting recesses are equidistantly opened on one side of each of the two conduit supports. A through hole is opened at one corner of the top of each of the two conduit supports. A fixed shaft is inserted through one end of each side of the second support bar, and the outer walls of the two fixed shafts are respectively inserted and connected to the inner walls of the two through holes.

[0008] In one example, the anti-detachment component includes a locking strip fixed at both ends of each limiting bracket, and the outer wall of each locking strip is interlocked with the inner wall of each connecting groove. A protrusion is fixed at the edge of both sides of the outer wall of each locking strip, and the outer wall of each protrusion is slidably connected with the inner wall of each limiting groove.

[0009] In one example, a take-up shaft is rotatably provided at one end of the inner wall of each connecting groove, a connecting rope is fixedly provided at one end of each clip, and each connecting rope is wound around the outer wall of each take-up shaft.

[0010] In one example, each of the winding shafts is connected to both ends with a torsion spring, and one end of each torsion spring is fixedly connected to one side of the inner wall of each connecting groove.

[0011] In one example, support frames are fixedly provided on both sides of the bottom of the mounting base plate, and U-shaped clips are fixedly provided at the bottom of the two support frames. Butterfly bolts are threadedly connected to the inner wall of one side of the two U-shaped clips, and one end of the two butterfly bolts passes through the inner wall of the two U-shaped clips and is connected to a gasket.

[0012] Compared with the prior art, the beneficial effects of this utility model are: by setting an adjustment mechanism on the catheter anti-tangling device, when sorting the infusion catheters, not only can multiple catheters be separated and sorted, but also catheters that deliver medication to different parts of the same patient's body can be pulled and adjusted in different directions. This solves the problems of catheters being alternately tangled due to the patient turning over and moving when using catheters for infusion in different directions, as well as the pulling of two catheters in different directions due to insufficient length.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5 This utility model provides a technical solution: an anti-entanglement device for oncology catheters, including a mounting base plate 1 and an adjustment mechanism 2 and an anti-detachment component 3 installed on the upper end of the mounting base plate 1;

[0021] The adjustment mechanism 2 includes a first support bar 201 rotatably mounted on one side of the mounting base plate 1, a second support bar 202 rotatably mounted at one end of the first support bar 201, and conduit supports 203 hinged to the lower edges of both sides of the second support bar 202. Multiple limiting brackets 204 are equidistantly mounted on one side of each of the two conduit supports 203. Multiple connecting grooves 205 are equidistantly opened on one side of each of the two conduit supports 203. Limiting grooves 206 are opened on both sides of the inner wall of each connecting groove 205. Multiple connecting recesses 207 are equidistantly opened on one side of each of the two conduit supports 203. One corner of the top of each of the two conduit supports 203... Through holes are provided at each point. Fixed shafts 208 are inserted through one end of each side of the second support bar 202. The outer walls of the two fixed shafts 208 are respectively inserted and connected to the inner walls of the two through holes. Fixed bolts are threadedly connected to the connection area between the first support bar 201 and the mounting base plate 1 and the connection area between the first support bar 201 and the second support bar 202. After adjusting the direction and distance, the fixed bolts are tightened to make it stable and prevent it from rotating on its own. When the anti-winding device is not used, the guide tube bracket 203 can be combined with the two sides of the second support bar 202 and fixed by inserting the fixed shafts 208 into the through holes for easy storage and transportation.

[0022] In use, the mounting base 1 is installed near the treatment bed. Then, the infusion catheters used for treatment are inserted between the limiting bracket 204 and the limiting groove 207 to classify and limit them, so that each catheter is separated. Then, according to the connection area of ​​the patient's body for different catheters, the fixed shaft 208 is pulled out to rotate the corresponding side of the catheter support 203, so that it rotates and adjusts the corresponding infusion direction. This allows multiple catheters in that direction to be interwoven and guided on the catheter support 203, so that they are separated from each other and can be guided in a targeted direction. This prevents the catheters in multiple directions from getting tangled together again when the patient turns over or moves, and also prevents the catheters connected in different directions from being pulled due to their length. This reduces the impact on the delivery of the treatment fluid. After the direction of the catheter support 203 is adjusted, the first support bar 201 and the second support bar 202 are rotated and adjusted so that the catheters connected in different directions have sufficient stretching distance, avoiding the phenomenon that the reserved catheter distance on one side is long and the reserved catheter distance on the other side is short.

[0023] Furthermore, the anti-detachment component 3 includes a locking strip 301 fixed at both ends of each limiting bracket 204, and the outer wall of each locking strip 301 is inserted and connected to the inner wall of each connecting groove 205. A protrusion 302 is fixedly provided at the edges on both sides of the outer wall of each locking strip 301, and the outer wall of each protrusion 302 is slidably connected to the inner wall of each limiting groove 206. When the limiting bracket 204 is pulled on the guide tube support 203, the protrusion 302 on the locking strip 301 slides in the limiting groove 206, thereby limiting it and preventing the locking strip 301 from detaching from the connecting groove 205, so that the limiting bracket 204 will not detach from the guide tube support 203.

[0024] Furthermore, a take-up shaft 303 is rotatably provided at one end of the inner wall of each connecting groove 205, and a connecting rope 304 is fixedly provided at one end of each clip 301. Each connecting rope 304 is wound around the outer wall of each take-up shaft 303, and one end of the connecting rope 304 is fixed on the clip 301, while the other end passes through the inner wall of the connecting groove 205 and is wound around the outer wall of the take-up shaft 303.

[0025] Each winding shaft 303 is connected to two ends with a torsion spring 305, and one end of each torsion spring 305 is fixedly connected to one side of the inner wall of each connecting groove 205.

[0026] When adding a catheter during use, a pull-limiting bracket 204 is installed on the corresponding catheter support 203, causing the locking strip 301 to slide in the connecting groove 205. This increases the distance between the limiting bracket 204 and the limiting groove 207, and also expands its opening area, making it easier to insert a connecting tube with a slightly larger end than the catheter. Then, the limiting bracket 204 is released, and under the elastic action of the torsion spring 305, the winding shaft 303 rotates to wind up the connecting rope 304. Driven by the connecting rope 304, the locking strip 301 automatically retracts into the connecting groove 205, thereby causing the limiting bracket 204 to lock onto the side wall of the catheter support 203, retracting the connecting end, limiting and separating the catheter connection. This makes the operation of adding catheters for infusion during tumor treatment more convenient, less likely to get tangled with other catheters, and also prevents some unused catheters from falling off from the top.

[0027] Furthermore, support frames 4 are fixedly installed on both sides of the bottom of the mounting base plate 1. U-shaped clips 5 are fixedly installed at the bottom of the two support frames 4. Butterfly bolts 6 are threadedly connected to the inner wall of one side of the two U-shaped clips 5. One end of the two butterfly bolts 6 passes through the inner wall of the two U-shaped clips 5 and is connected to a gasket 7. When using this anti-winding device, the mounting base plate 1 is supported by the support frames 4. Then, the U-shaped clips 5 at the bottom are clamped at the head of the patient's bed. Then, the butterfly bolts 6 are rotated so that the gaskets 7 cooperate with the inner wall of the U-shaped clips 5 to press against the head of the bed to fix and support it.
