Abstract

The invention relates to a biological indicator for sterilizing medical instruments. The biological indicator comprises a container, fungus pieces and an ampoule filled with a culture medium, the container comprises an outer tube and a cap, the upper end of the outer tube is provided with an outer tube opening, and the cap is installed at the upper end of the outer tube; a resistance limiting structure which allows the upper end of the outer tube to be inserted into a cap cavity to limit the upper end of the outer tube from being pulled out of the cap cavity is arranged between the cap and theupper end of the outer tube; a side wall notch is formed in the side wall of the cap; the outer tube is in a stepped shaft shape and comprises an outer tube large-diameter section and an outer tube small-diameter section which are sequentially connected from the upper end of the outer tube to the lower end of the outer tube, and an outer tube stepped surface is arranged at the joint of the outertube large-diameter section and the outer tube small-diameter section; the resistance limiting structure comprises a cap elastic clamping hook arranged in the side wall notch, and the cap elastic clamping hook comprises a cap hook head protruding out of the inner surface of the side wall and stretching into the cap cavity; and the upper end of the outer tube is prevented from being pulled out of the cap cavity when the cap hook head abuts against the outer tube stepped surface. By arranging the resistance limiting structure, the cap can be prevented from accidentally falling off.

Description

[0001] This application is a divisional application with the application number: 201911216586.4, the application date: December 2, 2019, and the invention name: biological indicator for sterilization of medical devices. technical field [0002] The invention relates to a biological indicator for sterilization of medical equipment. Background technique [0003] In the sterilization process of medical devices, biological indicators are usually used to evaluate the sterilization effect. Chinese Invention Patent Application Specification CN110055299A discloses a biological indicator for sterilization indication, which includes a plastic cap, an ampoule, a plastic outer tube and a bacteria sheet. The plastic cap is mounted on the plastic outer tube to form a container, and the ampoule and the bacterial tablet are placed in the container. In order to allow steam to enter the container to contact the bacteria sheet during the sterilization process, air holes are provided on the pl...
