Description
Technical Field
[0001] The utility model relates to the technical field of blood cell analysis, in particular to a blood cell analysis device. Background Art
[0002] The blood cell analysis device is used to count and classify various cell parameters in the blood, and generally includes an optical system of a light source unit, a flow chamber and a photoelectric detection unit, wherein the flow chamber provides an optical detection area, so that the cell sample passes through the detection area of the flow chamber in sequence. The light source provides an irradiation beam to irradiate the detection area of the flow chamber. When the cell passes through the detection area, the irradiation beam irradiates the cell and scatters. The photoelectric detection unit collects and converts the detected scattered light into an electrical signal. The parameters of various cells in the blood can be obtained by processing and analyzing these converted electrical signals, so as to perform counting and classification. The existing blood cell analyzer can only place a single test tube at the detection port of the blood cell analyzer, and manually take it out after the detection is completed. When a large number of blood samples need to be tested, the test personnel need to place the test tubes one by one at the detection port of the blood cell analyzer, which is labor-intensive and easily leads to the mixing of the required test sample with the actual test sample, thereby causing errors in the subsequent test results. To this end, a blood cell analysis device is proposed. Utility Model Content
