Abstract

The invention discloses a mechanical sampling system of a dry-type blood cell analyzing device. The mechanical sampling system comprises a sampling groove 2, a capillary tube 4, a base 11, a supporting table 15, horizontal sliding rails 12, a spring clip 14, a bearing 16, a grip 18, a linear motor 13 for propulsion, a linear motor 17 for rotation, a permanent seat of the linear motor for propulsion, a permanent seat of the linear motor for rotation and a bearing permanent seat. The mechanical sampling system is suitable for the sampling of a complete blood cell analyzing device, is simple in structure and has good shock resistance, fast analysis speed and stable performance.

Description

technical field [0001] The invention relates to a medical device, in particular to a mechanical sampling system of a dry blood cell analysis device. Background technique [0002] Whole blood analysis is an important link for doctors to diagnose and analyze patients' conditions, and directly guides the development of follow-up medical behaviors. Hematology analyzers are instruments that specifically analyze whole blood. Various types of blood cell analyzers currently used clinically are mainly based on two types of methods: wet analysis technology and dry analysis technology. The former is based on the differences in physical and biochemical properties of different types of blood cells, based on flow cytometry in different flow paths and light paths, cell staining, light scattering, electrical impedance and other methods are used to distinguish and count cell types. The analytical instrument based on this method has mature counting and accurate results, and is widely used in...
