Efficient saliva collection device

Abstract

The invention discloses a high-efficiency saliva collection device, which includes a collection funnel, a funnel cover, a volatilization chamber for stimulating saliva secretion, a collection tube and a collection tube cover, the collection funnel and the funnel cover are connected through a connecting piece, and the The funnel cover can be seamlessly fastened on the collection funnel, the volatilization chamber for the saliva secretion-stimulating substance is provided on the fastening surface of the funnel cover, the saliva secretion stimulating pattern is printed on the inside of the funnel cover, and the collection tube The upper end is provided with an opening, and the bottom end is provided with a seal. The bottom end of the collection pipe is provided with a conical collection pipe bottom. The pipe skirt is pluggably connected to the collection pipe cover. The high-efficiency saliva collection device provided by the present invention has a simple structure, is convenient to use, avoids separate cumbersome steps, uses two nerve reflection modes of smell and vision to stimulate saliva to accelerate secretion, and shortens sample collection time.

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 ...

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 sali...
