A saliva collector and method thereof

Abstract

The invention relates to a saliva collector, comprising a bracket, on which a disposable saliva collection mechanism and a liquid receiving tube are detachably arranged; the upper end of the bracket is connected with a VR assembly through a longitudinal support frame; the support frame is also provided with There is a taste distribution mechanism and a controller; the saliva collection mechanism includes a connected oral unit and an oblique liquid collection pipe; the inner lower end of the liquid collection pipe is coaxially connected with an inner ring; the lower end of the inner ring is provided with a movable Disassemble the connecting piece connecting the liquid receiving pipe, and the upper end is provided with a spiral scraping piece for scraping the saliva on the inner wall of the liquid collecting pipe; The rotating assembly is controlled by the controller; the upper end of the liquid collection pipe is connected with a liquid injection tube, and the bracket is provided with a syringe pump assembly for injecting saliva preservation solution into the liquid injection pipe, and the syringe pump assembly is controlled by the controller; the detection process Very comfortable, with high saliva collection efficiency, reduced saliva residue, and guaranteed sampling success rate.

Description

technical field [0001] The invention relates to the technical field of saliva collection, more specifically, to a saliva collection device and a method thereof. Background technique [0002] The most convenient way to collect DNA samples for genetic testing is saliva, followed by blood. At present, the most popular method is to collect saliva samples for testing. The advantages are: painless and non-invasive, and the acceptance rate is high. Compared with blood collection Saliva collection is more convenient and free, and user acceptance is higher; [0003] At present, although most of the equipment for saliva collection is still very simple, most of them directly use the method of funnel and liquid pipe threaded connection, which not only has no sense of experience, but also tends to cause insufficient saliva volume and a large amount of residue on the inner wall of the funnel when sampling. , for a single person, the efficiency of saliva collection is extremely low.
