Description

An adjustable disposable sterile swab

technical field

The utility model relates to the technical field of medical tools, in particular to an adjustable disposable sterile swab.

Background technique

Disposable sterile swabs are mainly used to collect secretion samples from female cervix, respiratory tract and other parts in clinical diagnosis and treatment. The collected samples are used to meet the needs of clinical tests, including genetic testing, immunological testing and morphological testing. However, due to the relatively long length of swabs required to collect samples from female cervix, respiratory tract and other parts, the collected samples need to be automatically or manually added by clinical testing instruments. However, the length of the existing sample tube is relatively short compared to the swab used for sampling. Therefore, before testing this type of sample, it is necessary to transfer the sample to a sample tube of appropriate length, which affects work efficiency and increases pollution. and risk of error. In addition, some items need to be pretreated with reagents before testing. The distance from the swab in the tube to the bottom of the tube will affect the amount of reagents added, which will easily lead to reagent waste and pathogen dilution, resulting in increased costs and reduced detection rates.
