Saliva collector and method thereof

Abstract

The invention relates to a saliva collector which comprises a bracket. A disposable saliva collecting mechanism and a liquid receiving pipe are detachably arranged on the bracket; and the upper end ofthe bracket is connected with a VR assembly through a longitudinal supporting frame. A smell emitting mechanism and a controller are also arranged on the supporting frame. The saliva collecting mechanism comprises a buccal unit and an inclined liquid collecting pipe which are connected with each other; the lower end of the interior of the liquid collecting pipe is coaxially and rotationally connected with an inner ring; a connecting piece detachably connected with the liquid receiving pipe is arranged at the lower end of the inner ring, and a spiral scraping piece for scraping saliva on the inner wall of the liquid collecting pipe is arranged at the upper end of the inner ring; the liquid receiving pipe is obliquely arranged on the bracket, a rotating assembly for driving the liquid receiving pipe to rotate axially is arranged on the bracket, and the rotating assembly is controlled by a controller; the upper end of the liquid collecting pipe is connected with a liquid injection pipe,an injection pump assembly for injecting saliva preservation liquid into the liquid injection pipe is arranged on the bracket, and the injection pump assembly is controlled by a controller. The detection process is very comfortable, the saliva collection efficiency is high, saliva residues are reduced, and the sampling success rate is guaranteed.

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.
