Description

Sampling device for detecting novel coronavirus

Technical Field

One or more embodiments of the present disclosure relate to the field of virus sampling, and more particularly, to a sampling device for detecting a novel coronavirus.

Background

In recent years, the clinical severe viral pneumonia has been more and more, such as novel coronavirus COVID-19, H7N9 avian influenza and A, and many sporadic viral infections. For definitive diagnosis, virus test specimens are generally taken. For viral pneumonia, namely respiratory tract virus infection, a patient's pharynx swab specimen or nasopharynx swab specimen is conventionally taken and used for detecting virus nucleic acid PCR (polymerase chain reaction), defining the virus type and guiding prevention and treatment. The throat swab or nasopharyngeal swab is a swab which is rubbed on the pharynx or nasopharynx by a certain method after special treatment, and a certain amount of body fluid containing virus is adhered to the swab. However, both pharyngeal swab and nasopharyngeal swab sampling are deficient: 1. there is an increased risk of infection: the sampled staff and the patient need to be in close contact, and most viruses are infectious, so that the risk of infection of the staff is greatly increased; 2. low virus amount and high false negative rate: (1) Because the infected part is often the lower respiratory tract, the pharynx is only a passage for the gas exhaled by the lung, and the virus in the lung adheres to the surface of the mucosa of the pharynx when the gas is exhaled, the virus amount is less, and the virus can be wiped off by the swab; (2) The virus discharge of patients sometimes has fluctuation, namely, a plurality of periods of time are discharged more, a plurality of periods of time are discharged less, the conventional sampling method can only take samples at a certain time point, and the time point can be just in the period of less virus discharge, so that the samples can not be detected due to the fact that the virus content of the samples is too low. This is an important cause of high rate of clinical false negative at present.
