Description

Technical Field

[0001] The present application belongs to the technical field of medical or biological experimental equipment and instruments, and in particular relates to an anti-contamination collection accessory for bacterial inoculation. Background Art

[0002] Culture dishes are essential basic laboratory instruments in the fields of medical testing, biological cultivation, etc. They are mainly used to create a relatively stable and suitable culture environment, while isolating the internal and external environments to prevent external interference and avoid leakage of internal cultures. During the culture process, the materials to be tested need to be inoculated or transferred to devices such as culture dishes. Due to the necessary procedures and preparations, the materials to be tested are generally not inoculated or used immediately after collection. Therefore, it is necessary to prepare sampling tools in advance to obtain and preserve the microorganisms to be cultured or tested. The corresponding tools must be used to preserve and isolate the corresponding materials, and they must be cultured after certain preparations and treatments. These tools include urine test cups and sampling tubes commonly found in hospitals. However, these common tools have simple structures and poor sealing. Since they need to be frequently operated or moved to the collection area for use during the collection process, the tools themselves and the materials collected inside are easily contaminated, which is not conducive to ensuring the accuracy of the subsequent culture test data. Summary of the Invention

[0003] The purpose of this application is to provide an anti-pollution collection accessory for bacterial inoculation that has better sealing, is more convenient to use, and can effectively ensure sealing performance during long-term storage, which is beneficial to improving the anti-pollution ability during material collection and preservation.
