Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a central venous indwelling catheter dressing fixing patch. Background Art

[0002] Hemodialysis (English name: Hemodialysis) refers to the process of extracting blood from the body, passing it through the permeable membrane of a hemodialysis machine, removing metabolic waste and impurities from the blood, and then transporting the purified blood back into the body. It is commonly known as "kidney dialysis" and "blood washing". Hemodialysis can be used for patients with renal failure or in situations such as blood poisoning where the body cannot excrete toxic substances on its own. Extending the dialysis time can reduce the complications of hemodialysis, increase the quality of life, and reduce mortality. The main reason is that the dehydration rate is lower and more uremic toxins can be removed. The best way is to use the time of sleeping every night for hemodialysis, which will not affect daily life compared to daytime dialysis.

[0003] Since the blood coagulation ability of hemodialysis patients is poor, and the central venous catheter used in dialysis is relatively thick and generally located in a larger vein, leakage may occur. Therefore, it is necessary to add hemostatic cotton at the opening where the main tube of the catheter passes through the skin to prevent blood from contaminating other locations. The commonly used method for fixing the hemostatic cotton, the main tube and the catheter branch is to use dressing gauze and bandages, but the use of bandages is not convenient. Every time the medical staff replaces the hemostatic cotton, they need to re-fix the catheter branch and the main tube separately, which is a troublesome operation. Utility Model Content

[0022] The central venous indwelling catheter dressing fixing patch of the preferred embodiment of the utility model is as follows Figure 1-3As shown, the dressing body 10 is square, and the dressing body 10 is a single-layer or multi-layer fabric structure. A window 20 is provided on the dressing body 10, and the cover window 20 is located on the center piece of the dressing body 10. An elastic cover sheet 30 covering the window 20 is detachably provided on the front side wall of the dressing body 10, and one end of the elastic cover sheet 30 is connected to the dressing body 10. Generally, the elastic cover sheet is a single-layer fabric with elasticity, which can be integrally provided with the dressing body or sewn separately. A through hole 40 is provided on the dressing body 10 below the window 20 for the branch pipe 200 of the catheter to pass through. Fixing positions 50 for fixing the branch pipe 200 are provided on the left and right sides of the window 20 on the dressing body 10. A folding portion 60 that can be folded forward is transversely disposed at the upper end of the dressing body 10, the left and right length of the folding portion 60 is greater than the left and right width of the dressing body 10, a first Velcro female patch 70 is disposed in the middle of the rear side wall of the folding portion 60, and first Velcro male patches 80 are disposed at both left and right ends of the rear side wall of the folding portion 60, and the folding portion can be integrally disposed with the dressing body or can be sewn separately;

[0023] When in use, the catheter branch tube 200 passes through the through hole 40 forward so that the window 20 is aligned with the position where the main tube penetrates the skin. After alignment, the position is pressed with hemostatic cotton, and then the hemostatic cotton is fixed by the elastic cover sheet 30, and then the folding portion 60 is folded forward and attached to the fixed position 50, and then the branch tube 200 is folded up and attached to the folding portion 60, and further through the connection and cooperation of the first Velcro female patch 70 and the first Velcro male patch 80, the end of the folding portion 60 can fix the branch tube 200 on the fixed position 50; and the main tube 300 of the catheter is pressed on the patient's body by the dressing body 10 and fixed together with the fixing effect of the branch tube 200, thereby improving the overall stability of the catheter after fixation; wherein, the cooperation between the window 20 and the elastic cover sheet 30 can facilitate the fixing of the hemostatic cotton and is also convenient for replacement, without the need to remove the entire dressing body, and the operation is convenient.
