Description

A auxiliary device for nucleic acid is examined thoughtlessly

Technical Field

The utility model relates to the technical field of medical auxiliary equipment, in particular to an auxiliary device for nucleic acid is examined thoughtlessly.

Background

At present, place the reagent bottle at the desktop usually when nucleic acid is examined thoughtlessly, then gather ten specimens in proper order and put into the reagent bottle, but the size of reagent bottle is more slender, and during the state of uncapping, if the desk receives the collision, the condition that topples over appears very easily in the reagent bottle, leads to the sample to be destroyed. At this time, the sampling is required to be performed again, which brings great inconvenience to the work of medical staff. After the nucleic acid mixture is sampled, the specimen is preserved as follows: firstly, the medical staff needs to unscrew the cover of the reagent bottle, place the cover on the table, then break the breaking point of the sampler (i.e. swab) with both hands, finally place the specimen in the reagent bottle, and screw back the bottle cover. Therefore, the operation of placing the specimen into the reagent bottle is complicated, time and labor are wasted, and the operation is not beneficial to the medical personnel to carry out nucleic acid collection.

The prior art CN 212844400U provides a sampling device for an infection management department, and the device is provided with a fixing mechanism and a shearing mechanism. The fixing mechanism is used for fixing the test tube, and the shearing mechanism is used for shearing the cotton swab, so that the step of manually breaking the swab is reduced.

However, this system still has the following drawbacks: a. the effect of preventing empting that the centre gripping subassembly played the sample preservation test tube still is not enough, because the centre gripping subassembly is not firm with the connection reliability of placing the desktop, in addition the centre gripping subassembly is not together fixed with the screw capping subassembly with cut off the subassembly, consequently still probably the condition that bumps down appears, and the condition that the aversion also appears easily in the centre gripping subassembly moreover. b. The screw cap assembly is too complex and requires multiple structures to be used in cooperation, which increases the cost. In the actual operation process, after the breaking operation of the swab head is completed every time, the bottle cap of the reagent bottle does not need to be screwed, only needs to be covered on the bottle body, and after the corresponding collection quantity is completed, the bottle cap is screwed. Therefore, there is a need for improvement of the prior art.
