[0002] Hemodialysis drains blood from the body to the outside of the body and passes it through a dialyzer composed of countless hollow fibers. The blood and an electrolyte solution (dialysate) containing electrolytes at concentrations similar to those in the body are exchanged inside and outside the hollow fibers through the principles of diffusion, ultrafiltration, adsorption and convection, thereby removing metabolic waste from the body and maintaining electrolyte and acid-base balance. At the same time, the body removes excess water and the purified blood is returned. The entire process is called hemodialysis.

[0003] For example, a critical care hemodialysis catheter fixing device with publication number CN202320682699.9 includes a base, a column is fixed on the upper end of the base, three sets of collars are sleeved on the column, a fastening bolt 1 is installed on one side wall of the collar, and a telescopic column is fixed on the side wall of the collar opposite to the fastening bolt 1. The beneficial effect is that: the utility model is provided with a collar, a fastening bolt 1, a telescopic column, a fastening bolt 2 and a holder, and in the process of fixing the catheter, the spacing between the holders can be adjusted by the collar according to the length of the catheter, and the holder is fixed by the fastening bolt 1 and the position of the holder is adjusted by the telescopic column, and the holder is fixed by the fastening bolt 2, and then the catheter is fixed by passing through the limit groove. In this way, the catheter can be fixed in three sections, the fixing area is increased, and the entanglement or fetters to medical staff due to the long length is effectively prevented, and the fixing effect is good, and the practicality of the device is improved.

[0004] The above patent proposes that when the dialysis catheter fixing device is used and adjusted, the operator needs to adjust the fastening bolt 1 and the fastening bolt 2 respectively to adjust the height and length of the fixing device. This adjustment method makes it inconvenient for medical staff to use it with one hand if they hold other items in their hands.

[0005] Therefore, we propose a dialysis catheter fixing device to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a dialysis catheter fixing device to solve the problem that the operator can adjust the height and length of the fixing device by adjusting the fastening bolt 1 and the fastening bolt 2 respectively in the above-mentioned background technology. Such an adjustment method makes it inconvenient for medical staff to use the fixing device without one hand if they hold other objects in their hands.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dialysis catheter fixing device, comprising a column, a connecting groove is provided in the middle of one side of the outer wall of the column, and clamping grooves are provided at both ends of the inner wall of the connecting groove, and a fixing component is movably embedded in the inner cavity of the connecting groove, and the fixing component is used to fix the position of the dialysis catheter;

[0010] Preferably, elastic elements are fixedly mounted at the middle of both sides of the outer wall of the long round rod, a round clamping ball is fixedly mounted at one end of the elastic element, and a driving handle is fixedly mounted at one end of the long round rod.

[0011] Preferably, the winding mechanism comprises a semicircular block and a concave block fixedly mounted on one end of the outer wall of the semicircular block, and a long rod is fixedly mounted in the inner cavity of the concave block.

[0012] Preferably, an inserted magnetic block is fixedly mounted on the other end of the outer wall of the semicircular clamping block, and a limited position circular block is movably mounted on one end of the semicircular clamping block.

[0013] Preferably, a through groove is provided at one end of the limiting circular block, and magnetic patches are embedded around the outer wall of the other end of the limiting circular block.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1: Please refer to Figure 1-3A dialysis catheter fixing device comprises a column 1, a connecting groove 2 is provided in the middle of one side of the outer wall of the column 1, a plurality of circular slots (not shown in the figure) are linearly and evenly spaced in the middle of both sides of the inner wall of the connecting groove 2, and a clamping groove 3 is provided at both ends of both sides of the inner wall of the connecting groove 2, and a fixing component 4 is movably embedded in the inner cavity of the connecting groove 2, and the fixing component 4 is used to fix the position of the dialysis catheter, and the fixing component 4 comprises a limiting mechanism 41 and a micro-electric telescopic column 42 fixedly installed at one end of the limiting mechanism 41, and a winding mechanism 43 is fixedly installed at one end of the micro-electric telescopic column 42, and the limiting mechanism 41 is used to drive the micro-electric telescopic column 42 and the winding mechanism 43 to adjust the height, and the micro-electric telescopic column 42 is used to drive the winding mechanism 43 to adjust the length.

[0024] The winding mechanism 43 includes a semicircular block 431 and a concave block 432 fixedly installed on one end of the outer wall of the semicircular block 431, a long rod 433 is fixedly installed in the inner cavity of the concave block 432, an inserted magnetic block 434 is fixedly installed on the other end of the outer wall of the semicircular block 431, a limiting circular block 435 is movably installed on one end of the semicircular block 431, a through groove 436 is provided at one end of the limiting circular block 435, and magnetic stickers 437 are embedded around the outer wall of the other end of the limiting circular block 435. The long rod 433 and the through groove 436 are movably installed, so that one end of the limiting circular block 435 is movably installed in the inner cavity of the concave block 432, and the magnetic sticker 437 at the other end of the limiting circular block 435 is magnetically connected to the inner cavity of the inserted magnetic block 434 for magnetic fixation.

[0025] In this embodiment: when the medical staff fixes the catheter, they pull out one end of the limiting circle 435 from the inner cavity of the inserted magnetic block 434, open the blocked gap of the semicircular block 431, place the catheter into its inner cavity through the gap of the semicircular block 431, and rotate the limiting circle 435 again, so that the magnetic patch 437 embedded in one end of the limiting circle 435 is inserted into the inner cavity of the inserted magnetic block 434 for magnetic connection and fixation, and then the catheter is fixed and fixed in the inner cavity of the semicircular block 431. This arrangement allows the medical staff to loosen the catheter directly by loosening the limiting circle 435 when they need to loosen the catheter midway, which is convenient to use.

[0026] Embodiment 2: This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 4The limiting mechanism 41 includes a long round rod 411 and concave round blocks 412 fixedly installed at both ends of the outer wall of the long round rod 411. A hollow ring 413 is movably embedded in the inner cavity of the concave round block 412. An outer rolling ring 414 is fixedly installed around the outer surface of the hollow ring 413 through short columns. When the long round rod 411 moves in the inner cavity of the connecting groove 2, the outer rolling ring 414 will drive the hollow ring 413 to limit movement in the inner cavity of the concave round block 412.

[0027] An elastic element 415 is fixedly installed in the middle of both sides of the outer wall of the long round rod 411, a round clamping ball 416 is fixedly installed at one end of the elastic element 415, and a driving handle 417 is fixedly installed at one end of the long round rod 411. The long round rod 411 drives the elastic element 415 and the round clamping ball 416 to be movably installed in the inner cavity of the connecting groove 2, and the round clamping ball 416 is automatically embedded in the round clamping groove (not shown in the figure) provided in the middle of both sides of the inner wall of the connecting groove 2 under the elastic force of the elastic element 415, thereby completing the fixation of the setting position of the long round rod 411 in the inner cavity of the connecting groove 2.

[0028] In this embodiment: when the medical staff adjusts the setting height of the catheter on the column 1, they can use an angle to step on the lower end of the column 1 to fix it, and then directly move the handle 417 to drive the long round rod 411 to move in the inner cavity of the connecting groove 2. Since round clamping balls 416 are fixedly installed on both sides of the outer wall of the long round rod 411 through elastic elements 415, when the long round rod 411 moves, when the round clamping ball 416 encounters a round clamping groove (not shown in the figure) opened on the inner wall of the connecting groove 2, it will automatically be clamped into the inner cavity of the round clamping groove under the elastic force of the elastic element 415 for fixation, thereby completing the adjustment of the setting height of the long round rod 411.

[0029] Working principle: When fixing the catheter, the medical staff pulls out one end of the limiting round block 435 from the inner cavity of the inserted magnetic block 434, opens the gap of the blocked semicircular block 431, and places the catheter into its inner cavity through the gap of the semicircular block 431. The limiting round block 435 is rotated again, so that the magnetic sticker 437 embedded in one end of the limiting round block 435 is inserted into the inner cavity of the inserted magnetic block 434 for magnetic connection and fixation, and then the catheter is fixed in the inner cavity of the semicircular block 431. The medical staff adjusts the catheter. When the tube is set at a certain height on the column 1, the handle 417 is directly moved to drive the long round rod 411 to move in the inner cavity of the connecting groove 2. Since round clamping balls 416 are fixedly installed on both sides of the outer wall of the long round rod 411 through elastic elements 415, when the long round rod 411 moves, when the round clamping ball 416 encounters a round clamping groove (not shown in the figure) provided on the inner wall of the connecting groove 2, it will automatically be clamped into the inner cavity of the round clamping groove under the elastic force of the elastic element 415 for fixation, thereby completing the adjustment of the setting height of the long round rod 411.
