Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of nursing hemostasis, in particular to a hemostasis device for nursing in a hemodialysis room. Background Art
[0002] At present, the most commonly used vascular access for hemodialysis patients is arteriovenous fistula. Because the fistula puncture needle is thick and the needle hole is large, it is difficult to stop bleeding from the puncture site after dialysis is completed. It is necessary to press the needle hole with your fingers for about 20 minutes to stop the bleeding. Some patients need to press for a longer time to stop the bleeding.
[0003] A search revealed a Chinese patent with authorization number CN213606621U, which discloses an emergency hemostatic nursing band. This device allows the band to be placed around a suitable location on the patient's arm or leg for hemostasis. By inserting the clip into a rectangular slot, the band is wrapped around the patient's area of interest. The tightness of the band can be adjusted by turning a knob, replacing the traditional Velcro tourniquet and extending its lifespan. However, the aforementioned patent has the following shortcomings: The adjustment range for the band's length and tightness using only the knob is limited, making it unsuitable for individuals with varying body shapes. Furthermore, the band is made of rubber and will age over time, though the remaining components can be retained and reused. Utility Model Content
