Abstract

The invention relates to a biological indicator for sterilization of medical instruments, in particular to a container for the biological indicator. The container comprises an outer pipe and a cap. The cap is mounted at the upper end of the outer pipe; a cap through hole communicated with a pipe cavity of the outer pipe is formed in the cap; an outer pipe end wall is arranged at the lower end of the outer pipe; and the outer pipe end wall is provided with an end wall through hole communicated with the pipe cavity of the outer pipe. The end wall through hole is formed in the outer pipe end wall, so that the end wall through hole, the pipe cavity of the outer pipe and the cap through hole are communicated to form a smooth gas flow path; the gas flow path is used for circulation of steam in the disinfection process of a pressure steam sterilizer; and the steam circulation effect of the outer pipe can be improved by utilizing the convection principle, so that bacterial flakes in the container can be in more sufficient contact with the steam, and the indication of the biological indicator is more accurate.

Description

technical field [0001] The invention relates to a biological indicator for sterilization of medical equipment, in particular to a container of the biological indicator. Background technique [0002] 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 plastic cap. However, the usual container is long and thin, and the ventilation effect is not good, so that the bacteria sheet and the steam are not fully contacted,...
