Self-contained type biological indicator container

Abstract

The invention discloses a self-contained type biological indicator container. As an improvement, the self-contained type biological indicator container comprises a culture medium container and an upper end cover which is hermetically matched with the culture medium container, wherein a blocking seal layer is arranged on the culture medium container; the container is divided into an upper cavity body and a lower cavity isolating from each other through the blocking seal layer; an enclosed cavity body is formed by the upper cavity body and the upper end cover; allowance which can be relatively shifted in the axial direction is reserved between the upper end cover and the container; and a protruding breaking layer part is arranged on a part, corresponding to the blocking seal layer, of the inner part of the blocking seal layer. According to the self-contained type biological indicator container disclosed by the invention, both of a biological indicator carrier and a culture medium are sealed in the container and are isolated from the outside, so that external pollution is completely and effectively avoided; and in addition, the upper cavity body is arranged close to the upper part ofthe container, and a cavity body for storing the biological indicator carrier is formed by the upper cavity body and the upper end cover, so that disinfection and sterilization are conveniently carried out; and cooperation of the biological indicator carrier and the culture medium only requires pressing and rotation of the upper end cover. The self-contained type biological indicator container disclosed by the invention has a simple structure, is convenient to operate, and has no need of damaging of the container; and due to transferred vaccination, external interference is effectively avoided.

Description

Technical field [0001] The invention relates to a biological indicator container, in particular to a self-contained biological indicator container suitable for using gas as a sterilizing medium and integrating culture functions. Background technique [0002] In the field of gas sterilization effect detection, biological indicators are the only reliable basis for monitoring the effectiveness of sterilization. The current common practice is to transfer the sterilized biological indicator carrier to a culture vessel containing a culture medium for inoculation, and determine whether the sterilization is effective or not through a growth recovery experiment. The traditional method is cumbersome to operate, requires high environmental conditions, and has a high risk of contamination of the biological indicator by environmental microorganisms during the transfer process, which is prone to false positive and false negative results. [0003] Although the existing self-contained biological ...

AI Technical Summary

Problems solved by technology

This structure makes the biological indicator carrier at the blind end of the sterilization gas flow, which is not conducive to sterilization; and the medium needs to be released by breaking the glass container, which is inconvenient to operate and has the risk of damage caused by glass slag; secondly, the culture vessel cannot be formed In a closed space, the culture solution containing bacterial colonies inside is easy to dump and overflow, causing environmental pollution and safety risks
