Embodiment Construction

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0016] see figure 1 , is a schematic structural view of the respiratory virus respiratory collection tube 1 provided by the present invention. It includes a collection tube 11, a tube cover 12, an air blowing tube 13, and an exhaust tube 14.

[0017] The collection tube 11 is a 2 mL EP tube filled with 1 mL of preservation solution. The pipe cover 12 is threadedly connected to the mouth of the collection pipe 11, and its top surface is provided with two pipe holes for the blowing pipe 13 and the exhaust pipe 14 to pass through respectively. And outside the top surface, a latex sleeve 21 is also wrapped to provide sealing.

Abstract

The invention provides a respiratory collecting tube for respiratory viruses. The respiratory collecting tube for respiratory viruses comprises a collecting tube body, a sealing plug arranged at the tube opening of the collecting tube body, an air blowing tube, an exhaust tube and preserving fluid; the collecting tube is internally filled with the preserving fluid, the air blowing pipe is arrangedoutside the collecting tube, penetrates through the sealing plug to the inside of the collecting tube and is inserted into the preserving fluid, and the exhaust tube is arranged outside the collecting tube, penetrates through the sealing plug to the inside of the collecting tube and is not in contact with the preserving fluid; and sealing is kept among the air blowing tube, the exhaust tube and the sealing plug. The respiratory collecting tube for respiratory viruse solves the technical problem of high false negative of a sample, caused by a respiratory virus collecting mode in the prior art.

Description

technical field [0001] The invention relates to the field of virus sample collection devices, in particular to a breathing collection tube for respiratory viruses. Background technique [0002] At present, the collected samples of the new coronavirus mainly come from the respiratory tract (nasopharyngeal swab, expectoration, sputum aspiration, alveolar lavage fluid, tissue, etc.), which are highly infectious. It is mainly transmitted by respiratory droplets, aerosols, and contact. The population is generally susceptible. The current collection methods for the new coronavirus on the market are mainly oral swabs, sputum aspiration, and alveolar lavage fluid. The collected specimens were tested for nucleic acid to confirm the diagnosis of the novel coronavirus infection. However, due to these collection methods, the low viral load of the suspected patient itself, and nucleic acid extraction, the false negative rate of the sample is high. Contents of the invention [0003]...
