Oral fluid diagnosing instrument

Abstract

The invention relates to an oral fluid diagnosing instrument comprising a detecting test paper and a nano-porous substrate which are wrapped in an outer shell, wherein the outer shell consists of an upper shell, a middle shell and a lower shell; wherein a through hole and an embedding groove for placing the detecting test paper are arranged on the middle shell; a spring is arranged on the lower shell; an ejection block is fixed on the spring; a locating pin is extruded on the ejection block; connecting strips are arranged at the two ends of the detecting test paper; a locating hole is arranged on the nano-porous matrix; the nano-porous matrix is placed on the ejection block; a connecting strip is arranged on the nano-porous substrate; a blocking strip is arranged on the connecting strip; and a push hand is fixed on the side face of the nano-porous substrate. The oral fluid diagnosing instrument is simple in structure and convenient for operation, has the advantages that different detecting test paper can be replaced to ensure that any type of antigen and antibody can be detected, and the sample collecting part is effectively protected from external pollution and can be widely used for early-stage self-test of various infectious diseases and hospitals.

Description

technical field [0001] The invention relates to a diagnostic instrument, in particular to an oral fluid diagnostic instrument. Background technique [0002] Infectious diseases are one of the main killers of human beings. AIDS, various types of hepatitis, bird flu, etc., threaten human health and life all the time. For this major infectious disease, early diagnosis is particularly important. Early diagnosis is conducive to the treatment of patients as soon as possible, and also helps to control the spread of the disease. At present, the detection of "negative" or "positive" for infectious diseases is mainly through blood tests. However, the blood test generally needs to puncture the skin of the subject, which is a kind of traumatic examination. It not only brings pain to patients, but also increases the risk of medical staff being infected. In contrast, collecting oral fluids (including saliva and oral mucosal exudate) is a "noninvasive" test that is relatively simple, ...

Problems solved by technology

Therefore, more oral fluid will be retained in the sample collection part, reducing the efficiency of sample collection

In addition, the micron-level pore size is still relatively large, so that some tiny impurities in the sample can pass through and flow to the subsequent test paper, which will affect the test results; (2) The sample collection part is directly exposed outside the plastic shell, so that both Not conducive to clean operation, but also increases the length of the entire detector
