Abstract

The invention provides a sample diluting device and a reagent card for detecting a novel coronavirus antibody. The diluting device comprises a diluent sample adding bottle, wherein the diluent sampleadding bottle comprises a first dilution cavity and a second dilution cavity, which are arranged up and down and are separated by an inclined plate; the top of the first dilution cavity is provided with a sample adding hole for inserting a sample collection tube, one side of the high end of the inclined plate is provided with a groove which is through up and down, and the groove is located right below the sample adding hole; a liquid outlet is formed in the bottom of the second diluting cavity. The sample diluting device can perform gradient high-multiple dilution on antibodies in samples, avoids barb phenomenon caused by excessive antibodies, and is suitable for rapid screening and detection of large quantities of novel coronavirus samples; the reagent card not only can be used for typingdetection of IgM and IgG antibodies in blood of a virus infected patient, but also can be used for detection of total antibodies of the novel coronavirus in the blood, so that the detection rate of an early infected patient can be increased.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a sample dilution device and a reagent card for detecting novel coronavirus antibodies. Background technique [0002] In terms of early diagnosis of the new coronavirus, nucleic acid detection kits are widely used at present, that is, to detect the nucleic acid sequence of pathogens. Nucleic acid detection can play a key role in primary screening and diagnosis, but the positive rate and false negative rate of nucleic acid detection are low. There are certain problems, and this method has high requirements for the site and testing personnel, so the development and application of on-site rapid detection products are accelerated, starting with blood antibody detection, establishing a rapid primary screening kit, and combining nucleic acid detection with antibody detection as soon as possible , It is of great significance to provide on-site batch screening and imp...
