Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of microbiological testing equipment, in particular to a microbiological testing instrument equipped with sample clamps. Background Art
[0002] Existing microbiology testing instruments lack an effective automatic sample transfer mechanism during manual sample collection, making them susceptible to contamination. This shortcoming primarily manifests in insufficient standardization and repeatability in sample handling. First, during manual sampling, microorganisms may be present on the operator's hands or tool surfaces. These bacteria or other contaminants can easily contaminate the sample during sampling and transfer, resulting in inaccurate test results and difficulties in subsequent analysis. This phenomenon is primarily due to the operator's skill level and the uncontrollable operating environment, such as failure to adhere to strict hand hygiene and instrument disinfection protocols during aseptic procedures.
[0003] Conventional countermeasures include enhanced operator training, the use of disposable instruments, and strict control of the operating environment. While these methods can reduce the risk of sample contamination to a certain extent, they also have some practical drawbacks. The use of disposable instruments increases operating costs, and frequent instrument replacement can lead to wasteful resources and affect overall laboratory efficiency. Therefore, we aimed to design a microbiology testing instrument with a novel structure to address this problem. Utility Model Content
