Blood routine analyzer detecting head

Abstract

The invention provides a detector head technical proposal used for a blood routine analysis meter for blood analysis. In the proposal, a blood expanding machine is arranged on a base; a light source support is arranged on the base on one side of the blood expanding machine and a collector support is arranged on the base on the other side of the blood expanding machine; three monochromatic sources which obliquely face to an upper plane on the blood expanding machine are fixed on the light source support, and an image collector is fixed on the collector support; the front end of the image acquisition unit is provided with an image acquiring lens; a cut-off filter is arranged on the rear of the image acquiring lens; a photoelectric coupler is arranged on the rear of the cut-off filter; a digital processor is connected to the rear of the photoelectric coupler; a USB interface is connected to the rear of the digital processor; the image acquiring lens is required to face to reflected light of the three monochromatic sources on the blood expanding machine; white light sources are arranged on the rear of the three monochromatic sources and the front end of the white light sources is provided with a rear optical collector; a diaphragm is arranged in front of the rear optical collector; a colordisc is arranged in front of the diaphragm; and a front optical collector is arranged in front of the colordisc.

Description

A detection head of a routine blood analyzer Technical field: The invention relates to a medical blood detection instrument, in particular to a detection head of a routine blood analyzer. Background technique: In the prior art, the known technology is the currently used blood analyzer using the "impedance method". This blood analyzer needs to add electrolyte solution reagents to the test blood to make the blood into suspended particles in the solution. When passing through the counting hole, the resistance change is detected. Therefore, when using this instrument to test blood, not only reagent processing is required, but also it is difficult to classify and count white blood cells. The test of red blood cells and white blood cells needs to prepare test samples twice, resulting in cumbersome detection operations and low test accuracy. Inaccurate, this is the weak point that existing technology exists. Invention content: The purpose of the present invention is to addre...

The test of red blood cells and white blood cells needs to prepare test samples twice, resulting in cumbersome detection operations and low test accuracy. Imprecise, which is the shortcoming of the existing technology
