AI Technical Summary

Technical Problem

When opening glass ampoules, manually breaking them open can easily cause medical staff to be cut by broken glass. The ampoule head is also prone to slipping out of their hands or breaking, posing a safety hazard.

Method used

Design an ampoule opener comprising an elastic protective sleeve and a grinding wheel. The elastic protective sleeve forms a receiving cavity that fits the head of the ampoule. The side wall has a deformation slit to wrap around the head of the ampoule, and the grinding wheel cuts scratches on the head of the ampoule to facilitate breaking it.

Benefits of technology

It effectively prevents medical staff from being cut by broken glass, ensures that the ampoule head is easy to collect after being broken, reduces safety risks, and improves the safety and convenience of operation.

Abstract

This utility model discloses an ampoule opener, relating to the field of medical auxiliary products technology. The ampoule opener has an elastic protective sleeve with a receiving cavity formed within it, at least partially adapted to the head of the ampoule. One end of the elastic protective sleeve has an opening connecting the receiving cavity to the external space; the side wall of the opening has a deformation slit. By inserting the ampoule through the opening into the receiving cavity, when it is necessary to break the ampoule head, the operator can pinch the outer wall of the elastic protective sleeve to apply force. The elastic protective sleeve isolates the operator's hand from the ampoule, preventing the operator's hand from being cut or pierced by broken glass. Furthermore, the broken ampoule head remains inside the elastic protective sleeve for easy collection. The deformation slit in the elastic protective sleeve allows the open end to be opened, accommodating ampoules of various sizes and improving its applicability.
