Example Embodiment

[0022] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0023] figure 1 Shown is a schematic diagram of a single-channel fluid circuit system in an embodiment of the present invention. From figure 1 It can be seen that, compared with the liquid circuit system of the three-division blood cell analyzer in the prior art, the liquid circuit system of the present invention does not include a quantitative module, but mainly consists of the following three modules: a sampling module 10, a counting module 20 and a pressure module 30. The fluid system only includes one sampling needle, one sampling channel and one counting module.

[0024] The sampling module 10 is used to collect blood samples and send the prepared samples to the counting module. The figure shows a single-channel liquid circuit system. The sampling module 10 includes a sampling needle 11, a sampling channel 12, and a quantitative container 13. Th...

Abstract

The invention provides a liquid path system for a three-differential blood cell analyzer, a portable three-differential blood cell analyzer with the liquid path system, and an operation method of the three-differential blood cell analyzer. The liquid path system comprises a sampling module for sampling module and transporting a blood sample, a counting module for count analysis of blood cells, a pressure module for establishing a pressure in the liquid path system and driving the liquid to move, a first small container with a quantitative dilution, a second small container with a quantitative dilution and a third small container with a quantitative hemolytic agent. The liquid path system realizes the function of a quantitative module in a conventional liquid path system for the three-differential blood cell analyzer is realized by adopting three small containers with the quantitative dilution or the quantitative hemolytic agent and cooperating manual operations. Besides, moving components and the motor are not used in the sampling module, so that the structure is simplified and maintenance cost is reduced. The three-differential blood cell analyzer with the liquid path system has portability and is more suitable for use in villages and towns.

Description

technical field [0001] The invention relates to the field of medical testing equipment, in particular to a three-class blood cell analyzer. Background technique [0002] There are two types of traditional three-differentiation blood cell analyzers: automatic and semi-automatic. The main difference lies in the amount of manual participation in the processing of the blood to be tested. When the automatic three-differentiation blood cell analyzer is working, you only need to shake the blood in the anticoagulant tube, insert the sampling needle into the blood, and press the start button to complete the whole work process; More manual participation is required, and different manufacturers implement different methods. The realization method similar to this method is that there are two sampling needles in the liquid path, shake the blood in the anticoagulant tube well, insert the first sampling needle into the blood and press the start button, the first sampling needle is sucked i...
