Abstract

The invention belongs to the technical field of medical treatment detection equipment, and particularly relates to a hematology analyzer adopting a single negative pressure source and a pipeline flow regulator. The hematology analyzer comprises a diluent container, a hemolytic agent container, a cleaning agent container, a cleaning pond, a hollow blood sample taking needle, a needle transferring device, a photoelectric colorimetry device, a No.1 diluting colorimetric pond, a No. 2 diluting pond, a metering and measuring device, a waste liquid bottle, a constant pressure device and a negative pressure pump connected with the constant pressure device. The hematology analyzer is characterized in that the constant pressure device and the negative pressure pump are of one group to form the single negative pressure source, all devices are connected with one another through pipelines, and an electronic valve and a flow regulator are arranged on the pipeline. According to the hematology analyzer provided by the invention, the single negative pressure source is matched with a corresponding quantitative pipeline device, so that works that a blood sample, a testing reagent and waste liquid in processes of sampling, reagent injecting, uniform-mixing, detecting, discharging and the like of the hematology analyzer enter specific positions through specified channels according to specified dosage in sequence, and the like are completed, and thus an accurate detection result is ensured.

Description

technical field [0001] The invention belongs to the technical field of medical clinical testing equipment, in particular to a blood cell analyzer using a single negative pressure source and a pipeline flow regulator. Background technique [0002] In the field of modern clinical laboratory medicine, blood routine examination is one of the most basic and important inspection items. The purpose of this examination is to understand the number, shape, ratio and other data of various cells and important components in the blood, as an important basis for clinicians to make a diagnosis. [0003] The existing blood routine examination mainly adopts the machine method, firstly, the machine automatically or semi-automatically quantifies, dilutes, and stains the blood sample, and then uses the Coulter principle (electrical impedance method) and photoelectric colorimetric principle , laser diffraction principle, sheath flow technology and other technical means to count and calculate...
