Description

Technical Field

[0001] The utility model relates to the field of storage equipment, in particular to a biological indicator outer tube structure. Background Art

[0002] In daily hospital work, sterilization of medical devices is an important part. How to ensure that medical devices are sterilized properly is of utmost importance. Modern hospitals use chemical and biological methods to test whether sterilization is qualified. Both methods are usually completed through sterilization process challenge devices. Among them: the biological method is to place a biological indicator in a challenge device or directly into a sterilization device. After the sterilization work is completed, the biological indicator is cultured to observe whether there are surviving microorganisms in the biological indicator to determine whether the sterilization work is qualified. The biological method can more intuitively indicate the sterilization effect.

[0003] A Chinese patent document with publication number CN217157305U discloses a biological indicator, which discloses: a method for reading information of the biological indicator through an external reading and writing device to check whether the biological indicator is invalid or has been used, thereby avoiding multiple uses of the same biological indicator to cause cross infection;

[0004] However, there is still a shortcoming in the use of this device: in the process of taking and placing the culture ampoule, the outlet of the outer tube needs to be tilted downward so that the culture ampoule can be slowly taken out from the inside of the tube body. However, it is inevitable that the culture ampoule will accidentally fall to the ground after flowing out, causing the culture ampoule to shatter all over the ground, and then the broken culture ampoule needs to be cleaned.
