Description

Sharp instrument protection device

Technical field

The utility model relates to the field of medical instruments, and specifically to a protective device for sharp instruments.

Background technique

With the emergence and replacement of various new disposable sterilization packaging materials in hospitals, the protection of sharp instruments during packaging, sterilization, transportation, use, etc. has always troubled sterilization personnel.

At present, sharp instruments are usually packaged in paper plastic, non-woven fabric, crepe paper, etc. for disinfection after use and cleaning. However, it is common for the packaging bag to be punctured, the top of the instrument to be damaged, the instrument to be contaminated, and the staff to be injured.

The protection devices currently on the market are all just simple cylindrical rubber sleeves. When setting up, the rubber sleeve needs to be inserted by hand from the sharp part of the instrument, which makes it easy to cause accidental injuries during insertion, and for some devices with curved front ends. When the rubber sleeve is inserted into the rubber sleeve, the curved sharp section easily penetrates into the inner wall of the rubber sleeve and blocks the smooth insertion of the rubber sleeve, making the insertion process more time-consuming and laborious.

Therefore, it is necessary to make further improvements in the prior art.
