A quantitative sampling device

Abstract

The invention discloses a quantitative sampling and sample adding device, which comprises a quantitative sampling and sample adding machine (1) and a quantitative liquid storage mechanism (2), wherein the quantitative sampling and sample adding machine (1) comprises a quantitative dual-purpose suction head (11); the front end of the quantitative dual-purpose suction head (11) is provided with a quantitative sampling suction head (12); the tail end of the dual-purpose suction head (11) is provided with a sampling hole (13); the end surface of the quantitative dual-purpose suction head (11) on the root part of the quantitative sampling suction head (12) is provided with a liquid sample discharging hole (14) communicated with the sampling hole (13); a sample adding hole protection cover (16) is sheathed on the tail end of the dual-purpose suction head (11); one section, which is provided with a liquid storage area (21), on the quantitative liquid storage mechanism (2) is sealed; the opening of the other section is used for inserting the quantitative sampling and sample adding machine (1). According to the quantitative sampling and sample adding device, automatic quantitative sampling, attenuation and sample adding can be carried out, and the quantitative sampling and sample adding device has the advantages of simple structure and convenience in use and is suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to medical devices used for bedside rapid diagnostic blood sample processing, in particular to a quantitative sampling and sampling device integrating quantitative sampling, dilution and quantitative sampling. Background technique [0002] Point-of-care rapid diagnosis (POCT) is a revolutionary and rapidly developing field in laboratory medicine. It has the advantages of fast and convenient, less specimen usage, simple operation, and low comprehensive use cost. Simple and fast testing methods are necessary for the implementation of POCT. condition. The collection and processing of blood samples is a key step in performing POCT. The traditional blood sample production process is to squeeze the blood collected by the blood collection tube into the reagent tube containing the reagent, mix it evenly, then use the dropper to draw the mixed solution and squeeze it into the detect...
