Description

A cuff with simultaneous positioning and fracture function holes

Technical field

The utility model relates to a medical device, in particular to a belt for increasing partial filling or hemostasis of a vein, in particular to a pressure pulse belt having a positioning and breaking function hole at the same time.

Background technique

In the prior art, the hose type cuff belt has problems such as repeated use, staggered use, and incomplete disinfection, and there is a case where the cuff is unsanitary.

As an improved type of hose-type cuff, the disposable cuff is mostly in the form of long strips, which are individually packaged in strips. The nursing staff is used in high-frequency use, and the working efficiency is affected by the disassembly and packaging. The work efficiency is greatly reduced.

In addition, when the continuous pressure cuff is used, the cuff is separated from the entire cuff belt, because the box matched with the cuff can not automatically identify each cuff. The length requires the user to pay attention to the length of the extraction during the extraction of the cuff. The prior art generally adopts a method of assisting the identification, such as marking a prominent mark near the broken line, such as marking a red dot or other color, in order to prompt the user to break the position of the vascular band to help the user know. Where there is a broken line, and then use another auxiliary mechanism, such as beading, serrated beading, etc., press the cuff around the broken line, and then forcefully pull the cuff monomer from the whole cuff come out.
