Technical Field
The utility model relates to an pass catch disease and detect technical field, in particular to virus specimen collection system.
Background
Generally, respiratory tract samples are required for pneumovirus examination, and include pharyngeal swabs, nasopharyngeal aspirates, sputum, respiratory tract aspirates, bronchial lavage, alveolar lavage, and the like. Different sampling sites have a large impact on the detection rate. The parts for collecting nasopharyngeal swab and oropharyngeal swab samples are all in the upper respiratory tract with lower virus concentration. Lower respiratory tract samples with higher virus concentration, such as alveolar lavage fluid and deep sputum, are better detection samples, but such a sampling mode is not usually carried out for mild patients.
Moreover, because some virus pneumonia specimens are infectious, workers who take throat swabs are in danger, and a large amount of protective equipment needs to be invested and a series of measures need to be taken to reduce the infection risk. Therefore, there is also a great need for a low risk method of collecting pneumonia specimens.
