Technical Field

The application relates to the technical field of virus sampling, in particular to a reagent bottle for detecting respiratory viruses.

Background

Coronavirus is a large virus family, and people infected with coronavirus are usually characterized by respiratory symptoms, which can cause pneumonia, severe acute respiratory syndrome and even death. At present, the situation of preventing and controlling novel coronavirus is still serious, and as the first step of nucleic acid detection, the importance of sample collection and preservation is undoubted. The sampled coronavirus needs to be separated by a centrifugal machine, so that researchers can analyze the virus conveniently.

The existing Chinese application with the publication number of CN206491871U discloses a respiratory virus sampling bag, which comprises a storage tube and a sampling swab, wherein the storage tube comprises a tube body and a tube cover, a swab virus storage solution is filled in the tube body, the tube cover is in threaded connection with a tube opening of the tube body, a through hole which is communicated up and down is formed in the tube cover, a sealing plug is arranged on the through hole, the sampling swab comprises a swab rod, the swab rod is a transparent hollow plastic tube, a sampling head is arranged at one end of the swab rod, the sampling head is formed by winding nylon fibers, the outer surface of the sampling head is communicated with an inner cavity of the swab rod, a handheld part is arranged at the other end of the swab rod, and a groove which is convenient for breaking the handheld part is arranged at the connection part of; after the swab rod finishes sampling, the tube cover is unscrewed, the sealing plug is taken down, the handheld part penetrates through the through hole from bottom to top until the groove is higher than the upper surface of the tube cover, the handheld part is broken off at the groove, and then the tube cover is screwed tightly, so that the sampling head can penetrate into the position below the liquid level of the swab virus preservation solution.

However, the above prior art solutions have the following drawbacks: the sampling personnel need unscrew the tube cover and incline the body and pour out swab virus preservation liquid, and swab virus preservation liquid spills easily or is infected with on sampling personnel's the hand, causes sampling personnel to have the risk of infecting the virus.

SUMMERY OF THE UTILITY MODEL

In order to promote the security when sampling personnel take a sample, the purpose of this application is to provide a respiratory track is reagent bottle for virus detection.

The above application purpose of the present application is achieved by the following technical solutions:

the utility model provides a respiratory track virus detects uses reagent bottle, includes bottle and bottle lid, the bottle is used for splendid attire swab virus to preserve liquid and the swab pole of wiping after the sampling, bottle lid and bottle opening threaded connection, the bottle is made by transparent flexible material, it is equipped with the perforation to run through on the roof of bottle lid, be equipped with the drip head with the perforation intercommunication on the roof of bottle lid, be equipped with the drip hole on the roof of drip head, the top of bottle lid is equipped with the sealing member that is used for sealed drip hole.
