Description

Disposable corona virus nucleic acid sampling test tube

Technical Field

The utility model relates to a medical test tube technical field, concretely relates to new coronavirus nucleic acid sampling test tube of disposable.

Background

Need use nucleic acid sampling test tube and disposable nasopharynx swab sampling rod during the sampling, wherein, the nucleic acid sampling test tube comprises releasable connection's body and pipe cap, and disposable nasopharynx swab sampling rod is by elongated sampling rod and the sampling swab that is located the stick head, and the position that the sampling rod front end is close to the sampling swab group has the crease portion of easily breaking. The inventor finds that the problems of the sampling of the new coronavirus nucleic acid at present are as follows in long-term first-line sampling work:

firstly, the method comprises the following steps: the test tube and the test tube cap of collection are screwed up by screw thread rotation, and both need both hands to operate opening and covering, and also one hand holds the test tube, and the other hand holds the cap, wastes time and energy. If the cap is dropped carelessly, the cap is wasted.

Secondly, the method comprises the following steps: the test tube and the test tube cap are not integrated, so that the pollution of the surrounding environment or a specimen is easily caused, and the following reasons are mainly adopted: a. when sampling, the cap is screwed down on the working table or held on the same hand with the test tube in order to save trouble, so that the cap is easy to pollute and the detection result is influenced; b. when the nucleic acid is mixed and collected, the surrounding articles are polluted because the nucleic acid is unscrewed and covered for many times; if the cap is not screwed down, the sample preservation solution in the test tube leaks out to pollute the surfaces of a transfer box and other test tubes in the conveying process, and further cross infection is caused; d. when a test tube with a collected sample is detected in a laboratory, a cap needs to be opened to absorb the sample, the cap is placed on a table top and is easy to pollute the table top and surrounding articles, the cap needs to be screwed back again after the sample is absorbed, if a plurality of tubes are opened simultaneously, the risk of wrong cap covering is easy to occur, because the original cap is required to be covered back, the pollution among samples cannot be caused, and otherwise, the possible original tube can be influenced.

Thirdly, the method comprises the following steps: the sample pharynx swab stick is put into the test-tube, stretches into the test-tube with the stick head now, breaks off with the fingers and thumb along the crease of pharynx swab stick at the test-tube edge, nevertheless is very hard sometimes, can cause the pollution of surrounding environment by careless pop-out even.

Fourthly: because of the nucleic acid sample volume is big, detection work is busy, sometimes can take ten people to adopt the mode of mixing, need give the test tube number this moment, directly write on the test tube with the marker pen at present, and there are more literal information on the test tube, write the number again and can appear the condition that the handwriting is unclear, is difficult to discern.
