Saliva detector

Abstract

The invention relates to a saliva detector and belongs to the field of detection equipment. The detector comprises a saliva collecting device; the saliva collecting device is provided with a first accommodating cavity, a second accommodating cavity and a test strip mounting hole communicated with the second accommodating cavity; the saliva detector also comprises a positive pressure driving deviceand a saliva filtering device assembled to the saliva collecting device; the positive pressure driving device closes the first accommodating cavity and slides along the first accommodating cavity; thesaliva filtering device is used for filtering liquid in the first accommodating cavity and is communicated with the second accommodating cavity; the liquid is used for reacting with an immune colloidal gold test strip assembled in the test strip mounting hole. The saliva detector provided by the invention integrates saliva collection, pretreatment and inspection, and has the advantages of simplestructure, convenience and quickness in operation, no limitation imposed by site and other factors, fast detection, high sensitivity, high specificity and high safety.

Description

technical field [0001] The invention relates to a detector, in particular to a saliva detector, and belongs to the field of detection equipment. Background technique [0002] Saliva is one of the important exocrine fluids of the human body. Saliva can reflect the changing levels of various proteins and small molecules in the blood. Compared with blood and urine samples, saliva collection has the advantages of being fast, convenient, safe and non-invasive, and does not violate the privacy of the subject. Therefore, saliva detection is becoming a research hotspot with the most potential and application prospects. At present, it has good applications in infectious disease screening and drug concentration monitoring. For example, the Oral Quick saliva HIV rapid detection system has been approved by the US FDA, and its HIV antibody positive results are highly consistent with serum. The industry believes that saliva can replace Serum is used for monitoring and screening of HIV hi...

Problems solved by technology

However, in the practical application of drug detection, since the concentration of drugs and their metabolites in saliva is significantly lower than that in urine, and saliva is a mixture of various proteins, microorganisms, DNA, RNA, and fatty acids, its composition is complex and its viscosity is high. , high tension, which seriously affects the sensitivity, specificity and detection speed of the colloidal gold immunochromatographic detection of the competitive method

In addition, the resistance of drug addicts is reduced, and they are prone to respiratory infectious diseases such as tuberculosis. However, the existing drug immune colloidal gold test paper sampling devices are all open designs, which cannot prevent respiratory pathogens such as tuberculosis in the saliva samples of drug addicts from being transmitted through the air.
