Detailed Description
The invention is further illustrated by the following examples in conjunction with the accompanying drawings:
a neck dialysis catheter fixator as shown in fig. 1 to 4 has a plate-shaped fixator body 1, straight leg parts 1a are formed at the left and right ends of the fixator body 1, and a tether through hole 1aa is formed in each leg part 1 a. The middle part is bent to form a semicircular clamping part 1b, and the clamping part 1b is made of medical hard plastics or stainless steel. The middle part of the lower surface of the clamping part 1b is provided with a clamping seat 2, the length of the clamping seat 2 is smaller than that of the fixer main body 1, the left end and the right end of the clamping seat 2 are provided with two clamping grooves 2a side by side, the clamping grooves 2a are arranged in the front-back direction in a whole body mode, the clamping grooves 2a are semi-cylindrical, a plurality of pressing pieces 3 are arranged along the circumferential direction of the surfaces of the clamping grooves 2a, each pressing piece 3 comprises a latex base 3a, the latex bases 3a are fixedly connected to the inner walls of the clamping grooves 2a, the lower ends of the latex bases 3a are connected with pressing blocks 3b made of plastics, the whole body formed by the latex bases 3a and the pressing blocks 3. The pressing block 3b is screwed to the latex base 3a by a screw 3 ba. The lower end face of the pressing block 3b is provided with a plurality of latex cushions 3 c. The latex base 3a the place ahead and the card in rear portion 1b inner wall on respectively be provided with a set of gasbag, every group gasbag includes left gasbag 4, well gasbag 5 and right gasbag 6, left side gasbag 4 and right gasbag 6 bilateral symmetry, and be close to left and right branch foot portion 1a respectively, well gasbag 5 sets up on the central line between two draw-in grooves 2a, the inlet end of all gasbags is all from up passing card portion 1b down, and the suction nozzle setting is at the upper surface of card portion 1 b.
In the specific implementation process, the tether through hole 1aa arranged on the leg part 1a is used for binding and fastening a tether with the function similar to a magic tape, so that the device is convenient to use later, and the whole device is fastened on a patient. The clamping part 1b is used for arranging the clamping seat 2, and clamping the dialysis tube by forming a clamping groove 2a on the clamping seat 2. The length of the clamping seat 2 is smaller than that of the fixer body 1, which means that the length of the clamping seat 2 is smaller than that of the fixer body 1 in the front-back direction, so that a distance is left between the front and the back of the clamping seat 2 after the clamping seat is installed on the fixer body 1 for arranging an air bag. The internal surface that compresses tightly piece 3 settings at draw-in groove 2a is used for directly carrying out the elasticity oppression formula to the dialysis tubing stably, prevents to shift. The pressing piece 3 is arranged on the latex base 3b through a pressing block 3b, wherein the latex base 3b plays a role in elastic adaptation through the elastic performance of the latex base 3 b. The pressing block 3b is directly contacted with the dialysis tube to be pressed and fixed. The latex cushion 3c arranged on the pressing block 3b is used for increasing friction force and providing elastic contact, so that the whole adaptability is stronger. The effect of two sets of gasbags all is used for further stabilizing the dialysis catheter around, and each gasbag is through aerifing, oppresses fixedly at different positions to the dialysis catheter, simultaneously because self gas filled attribute, and is softer, and the adaptability is stronger. Wherein the middle air bag 5 is arranged at the middle position and presses and fixes the dialysis tube in the two clamping grooves 2 a.
The foregoing detailed description of the preferred embodiments of the invention has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions available to those skilled in the art through logic analysis, reasoning and limited experiments based on the prior art according to the concept of the present invention should be within the scope of protection defined by the claims.
