Embodiment Construction

[0014] The embodiment of the present invention and the assembly method of the instrument are now described in detail in conjunction with the accompanying drawings. 3 is the shell of the whole instrument. In principle, the housing can consist of any material and can be of any shape and color. The shell is connected together by fixing nails 8 from upper and lower parts 3a and 3b. The housing also serves as a handle for the entire device, which the subject can hold and then insert the capillary matrix of the device into the mouth. As two important units inside the instrument: 1 in the figure is the detection test paper; 2 is the capillary matrix. One end of the detection test paper is directly connected to one end of the capillary matrix or connected through a blocking strip 4 in the middle. The other end of the capillary matrix is ​​used to collect oral fluid and inserted into the subject's mouth. This end can be designed into any shape suitable for collecting liquid, such a...

Abstract

The invention provides a device and method for quickly collecting and detecting the liquid in mouth by one step. The device is an integrative unit and uses very little mouth liquid to analyze and the detection result can be read in display window of the device after several minutes without any subsequent lab processing procedure. The main part of the device comprises two parts: a collecting sample unit-capillary matrix, and a detecting sample unit-detecting test paper. A blockout strip is inserted between the capillary matrix and the detecting test paper and used for reducing the incidence rate of 'false positive'. The device and method can quickly collect and detect the mouth liquid, in order to determine the presence of the antigen or antibody of the virus such as AIDS, hepatitis and so on and to detect a variety of biomoleculars in the other human. The invention has simple structure and is easy to operate and suitable for mass production and used for early stage self check and hospital use of a variety of infectious diseases.

Description

technical field [0001] The invention relates to an instrument for detecting oral fluid by using immunochromatography. The feature of this instrument is that it is an all-in-one unit that rapidly collects and tests oral fluid samples in one go. The device consists of a hydrophilic capillary matrix to which is attached a test strip. This instrument can be used to quickly detect oral fluid to determine whether it contains antigens and antibodies of viruses such as AIDS and hepatitis, and can also be used to detect other biomolecules contained in the human body. technical background [0002] Infectious diseases are one of the main killers of human beings. AIDS, various types of hepatitis, bird flu, etc., threaten the health and life of human beings all the time. Taking AIDS as an example, since the first AIDS case was reported in China in 1985, the prevalence of AIDS has shown a rapid upward trend. According to the data released by the United Nations agency in China, there a...
