Sampling device of full-automatic chemiluminescent analyzer and sampling method of sampling device

Abstract

The invention provides a sampling device of a full-automatic chemiluminescent analyzer and a sampling method of the sampling device. The chemiluminescent analyzer comprises a sampling needle system, areagent needle system, a sample area, an injection area and a reagent area, wherein the sample area, the injection area and the reagent area are sequentially arranged from left to right; the samplingneedle system and the reagent needle system are fixed on a same transverse guide track; a reaction cup area perpendicular to the injection area is arranged between the reagent area and the sample area; needle cleaning devices are respectively arranged between the sample area and the injection area and the reagent area and the injection area; sampling positions of the sample area, the injection area, the reagent area and the two needle cleaning devices are on a same straight line; a sampling needle passes through sampling positions of the sample area and the injection area; a reagent needle passes sampling positions of the reagent area and the injection area. According to the sampling device of the full-automatic chemiluminescent analyzer and the sampling method of the sampling device, thesampling positions, the injection positions, grooves and a cleaning area are positioned on a same straight line, so that the injection speed is increased; the sampling positions and the injection positions are fixed, so that the error probability is reduced.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a sample adding device and a sample adding method of a fully automatic chemiluminescence analyzer. Background technique [0002] The chemiluminescence analyzer has the characteristics of fast detection speed, wide linear range and wide application range, and has been widely used in clinical immunodiagnosis. Normally, a chemiluminescence analyzer usually includes components such as a flow cell, a sample tray, a reagent tray, and a sampling device. The sampling device is used to absorb the samples in the sampling tray and the magnetic beads, R1, R2 and other substances in the reagent tray. , and mix them, and the mixture is sent to the flow cell for chemiluminescent reaction. [0003] Existing sampling devices are usually structures that can move linearly along the three directions of X, Y, and Z. When sampling, the sampling points can be distributed in the area covere...
