Problems solved by technology

Second, from the perspective of leukocyte classification, because the volume of the same cell is different at different stages of its growth, the volume of different types of leukocytes may overlap, for example: primary lymphocytes may have the same volume as late monocytes or Similarly, flow cytometers need to add special dyes to distinguish them, and use fluorescence to identify them, which increases the complexity of the instrument
In addition, laser flow cytometry cannot image cells

Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the embodiments.

[0026] Figure 4 shows the pictures of different cells at different developmental stages, and Figure 5 shows the pictures of partial crystallization in the urine sediment. It can be seen from the figure that the types and volumes of cells and urine sediments are quite different. It is not reliable to recognize and classify them by detecting their volume alone, but it is not too difficult for a trained naked eye to recognize them. The ideal inspection method should be: 1. Observe the cells one by one with the naked eye; 2. The number of observed cells should be as large as possible to increase the probability of finding specific cells. If the "machine eye" can be used to replace the naked eye in a short period of time to quickly observe cells in large numbers and one by one, and intelligently measure and classify the observed cells, it will greatly improve the level of clinical test...

Description

Technical field [0001] The invention relates to particle measurement technology, in particular to a flow imaging particle measurement device and a measurement method. Background technique [0002] Particle measurement technology is used in many fields such as industrial and agricultural production, scientific research and scientific experiment, medical research and clinical medicine, as well as pharmaceutical, chemical, and petroleum processing industries. For example: measuring particles in refined oil during petroleum processing, measuring particles in water during water purification, examining seawater red tide or river water pollution in environmental science, measuring the number, size and white blood cell classification of blood cells in clinical medicine, and urine sediment inspection and many more. Limited to the limitation of the detection principle followed by the existing technology, most of the existing measuring instruments can only measure indirectly based on the co...
