Description

Sampling device

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a sampler.

Background

The nasopharynx swab sampling mainly uses a disposable sampler, and the flocking sampling swab is widely used at present, so that the cost is low, and the sampling is simple. The flocking sampling swab is composed of a nylon short fiber fluff head and a plastic rod. However, in actual sampling operation, due to light, it is difficult for medical staff to visually collect the nasal cavity or throat of a patient regardless of whether the nasal swab or the throat swab is used for sampling, which affects accurate judgment of a sampling position and further affects a detection result. Taking the COVID-19 sampling as an example, medical staff can sample only by wearing protective tools such as goggles and protective screens, which can affect the sampling visual field, and if the sampling is not accurate, the subsequent nucleic acid detection result can be affected, false negative occurs, and epidemic prevention and control are affected. In addition, there is also an event that a glove of a medical staff touches the mouth of a person to be sampled during sampling, and the medical staff is not standardized in operation and is actually concerned with the design of a sampling rod. Therefore, there is a need for an improved sampler.
