Preliminary screening analyzer for blood donation and usage thereof

Abstract

The invention relates to the technical field of medical equipment, and in particular to a preliminary screening analyzer for blood donation and usage thereof. The preliminary screening analyzer for the blood donation comprises a mounting rack, a sample tray module, a probe module, a hemolysis and chylemia colorimetric module, a reagent refrigeration module, and an assay module; positioning parts for mounting the probe module and the hemolysis and chylemia colorimetric module are arranged on the mounting rack, the positioning parts can horizontally reciprocate relative to the mounting rack, sothe positioning parts have a first running direction and a second running direction; when moving along the first running direction, the probe module can sequentially suck the sample in the sample traymodule and the reagent in the reagent refrigeration module and inject the mixture of the sample and the reagent into the assay module; and when moving along the second running direction, the probe module can inject purified water into the sample tray module and suck and assay the mixture of the sample and the reagent. The invention can mitigate the technical problem existing in the prior art thatthe blood assay process is complex to operate and consumes a great deal of time and labor.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a blood donation primary screening analyzer and a method for using the same. Background technique [0002] China's voluntary blood donation is the process of collecting blood from healthy people. Before donating blood, blood donors must go through a preliminary blood test screening, which at least includes the detection of three indicators of alanine aminotransferase, hemoglobin and chyle blood in human blood. If one of the items is not met, blood donation cannot be performed. In the prior art, a dry-type biochemical analyzer is used for the detection of alanine aminotransferase. 30 ul of whole blood is sampled and added to the dry-type test strip, and then put into the instrument for about 120 seconds to obtain the detection result. For hemoglobin, the copper sulfate titration method is generally used for visual inspection, that is, a large drop of blood about 50ul is d...
