Detailed Description
The utility model will be further elucidated with reference to the drawings and the embodiments, which are exemplary only and do not limit the scope of the utility model.
As shown in fig. 1 and 2, a central venous catheter fixer comprises a gauze main body 1 and a positioning gauze 2 matched with the gauze main body 1; a fixing cavity 3 which is communicated front and back is arranged in the middle of the gauze main body 1; a first extension part 4 extends forwards from the front end of the bottom of the gauze main body 1, and a first positioning adhesive tape 5 extending forwards is arranged at the front end of the first extension part 4; two sides of the gauze main body 1 are respectively provided with a barrier strip 6, and a strip-shaped limiting hole is formed between each barrier strip 6 and the gauze main body 1; the positioning gauze 2 covers the gauze main body 1, two ends of the positioning gauze 2 respectively penetrate through the strip-shaped limiting holes and then extend outwards, and a second positioning adhesive tape 7 is arranged at each end of the positioning gauze 2. In the present embodiment, the first positioning tape 5 and the second positioning tape 7 are both single-sided tapes; a second extension part 8 extends backwards from the rear end of the bottom of the gauze main body 1; a third positioning tape 9 is provided on the rear end of the second extension 8. Specifically, the third positioning tape 9 is disposed on the top surface of the second extension portion 8; the third positioning tape 9 is a double-sided tape. The central venous catheter fixing device can conveniently fix the central venous catheter, can provide bearing force for the central venous catheter when being fixed, further enables the central venous catheter and the venous indwelling needle to be more stable, and meanwhile has the advantages of being attractive in appearance, convenient to use, low in manufacturing cost and the like; when in use, the central venous catheter bent into a U shape is inserted into the fixed cavity 3, and then the first positioning adhesive tape 5 is correspondingly adhered to the skin, so that the positioning of the fixator is completed, then pulling the two ends of the positioning gauze 2 to cause the top of the gauze main body 1 to be pressed down and pressed on the central venous catheter, thereby leading the central venous catheter to be fixed in the fixed cavity 3, then two pieces of second positioning adhesive tapes 7 are adhered to the skin correspondingly, so that the fixation of the central venous catheter is completed, then, the second extension part 8 is turned forwards to cover the rear end of the central venous catheter, and then the third positioning adhesive tape 9 is adhered on the top surface of the positioning gauze 2, thus completing the turning and fixing of the second extension part 8, thereby providing a bearing force for the central venous catheter and further preventing the central venous catheter from sagging.
