Efficient saliva collection device

Abstract

The invention discloses an efficient saliva collection device. The device comprises a collection funnel, a funnel cover, a saliva secretory substance stimulation volatilization chamber, collection tubes and a collection tube cover, wherein the collection funnel is connected with the funnel cover through a connection sheet, the funnel cover is seamlessly fastened on the collection funnel, and the saliva secretory substance stimulation volatilization chamber is formed in the fastening surface of the funnel cover; saliva secretory substance stimulation patterns are printed on the inner sides of the funnel cover, openings are formed in the upper ends of the collection tubes, and the bottom ends of the collection tubes are sealed; cone collection tube bottoms are arranged at the bottom ends of the collection tubes, tube edges extend to the bottom ends of the collection tubes, outer spiral screw threads are arranged on the outer sides of the openings of the upper ends of the collection tubes, and the tube edges are connected to the collection tube cover in a pluggable mode. The efficient saliva collection device is simple in structure and convenient to use, tedious steps of a split type are avoided, smell and vision neural reflex modes are used for simulating saliva to secrete quickly, and the sample collection time is shortened.

Description

technical field [0001] The invention relates to the technical fields of saliva collection, airtight storage and gene detection, in particular to a high-efficiency saliva collection device. Background technique [0002] Saliva can be used for early diagnosis and treatment of oral and dental diseases, and there may be biomarkers in saliva that reflect the health status of the whole body. In 2004, the United States launched a kit for detecting human immunodeficiency virus-1 (HIV-1) through saliva, which can detect HIV-1 infection within 20 minutes; "Saliva Methamphetamine / Morphine Colloidal Gold Test Strip" Can quickly test whether drug abuse; According to literature reports, there are 1166 proteins in human saliva, most of which can be found in plasma and tears at the same time, and disease-related biomarkers can be found from these proteins, followed by research It was found that the levels of C-reactive protein, α-1B glycoprotein, and creatinine in human saliva are related ...

AI Technical Summary

Problems solved by technology

However, these collection devices all have certain technical defects: ORAgene’s saliva collection device is a glass tube design, which is fragile and not as safe as a plastic tube; Inconvenient; the puncture point of the ORAgene saliva collector used to pierce the film of the storage cavity of the preservation solution exists only on one side of the funnel, and cannot effectively wash away the saliva spit on the other side; the DNAgard saliva collection device uses spit and preservation solution The separate method, although the washing and collection of saliva is more thorough, but the separate design structure will increase the steps of saliva collection operation, which is not convenient to use

[0005] More importantly, genetic testing requires a certain amount of saliva samples to be collected. For some people, the secretion of saliva is slow and the collection takes a long time.
