Saliva sample collecting device

Abstract

The invention relates to the technical field of saliva collection, in particular to a saliva sample collection device which comprises a base, a sampling tube, a sample storage mechanism, a protection mechanism, a first connecting mechanism and a second connecting mechanism, the sampling tube is used for extracting a saliva sample, preserving fluid is stored in the protection mechanism, the sample storage mechanism is used for mixing the saliva sample and the preserving fluid, the sample storage mechanism is connected with the sampling tube through a first connecting mechanism, and the sample storage mechanism is connected with the preserving mechanism through a second connecting mechanism; the first connecting mechanism is used for controlling the communication between the sample storage mechanism and the sampling tube, and the second connecting mechanism is used for controlling the communication between the sample storage mechanism and the protection mechanism. And the influence of external air on the saliva sample is reduced.

Description

Technical field [0001] The present invention relates to a technical field of saliva collection, in particular to a saliva sample collection apparatus. Background [0002] When genetic testing is performed, one type of sample is saliva, and some experiments use direct saliva collection method when collecting saliva, and a saliva collector is required. Saliva samples are easily damaged, resulting in a relatively short storage time of saliva samples, in order to extend the storage time of samples, after sample collection, a preservation solution is usually added to the sample, and the activity of the active enzyme in saliva is reduced by the preservation solution, thereby protecting the DNA sample in saliva. [0003] In view of the above related technologies, the inventor believes that there is a defect: the relevant technology needs to save the liquid to the saliva sample, and when the preservation liquid is added to the saliva sample, the cover of the saliva sample needs to be ope...

AI Technical Summary

Problems solved by technology

Saliva samples are easily damaged, resulting in a relatively short storage time for saliva samples. In order to prolong the storage time of samples, after sample collection, a preservation solution is usually added to the sample to reduce the activity of active enzymes in saliva through the preservation solution, thereby protecting the saliva. DNA sample

[0003] Regarding the above-mentioned related technologies, the inventor believes that there is a defect: in the related technologies, it is necessary to preserve the liquid in the saliva sample. When adding the preservation liquid to the saliva sample, it is necessary to open the cover of the saliva sample and add the preservation liquid to the saliva sample In this process, saliva is in direct contact with the outside air, and microorganisms such as bacteria in the air will fall into the saliva sample and contaminate the saliva sample
