Blood cell analyzer and cleaning method thereof

Abstract

The invention provides a blood cell analyzer and a cleaning method thereof. The blood cell analyzer comprises a mode setting module used for setting a working mode of the blood cell analyzer; a sampling distribution module, which is used for collecting blood samples and distributing the blood samples to the erythrocyte sedimentation rate detection module and / or the blood routine examination module; an erythrocyte sedimentation rate detection module, which is used for detecting the erythrocyte sedimentation rate of the blood sample; a blood routine detection module, which is used for performing blood routine detection on the blood sample; a liquid path supporting module, which is at least used for cleaning the sampling distribution module; a control device, which is at least used for controlling at least one of the erythrocyte sedimentation rate detection module and the blood routine detection module to operate according to a set working mode; besides, the blood cell analyzer is further provided with different cleaning modes, and the control device is further used for controlling the liquid path supporting module to execute the corresponding cleaning mode according to the set working mode so as to clean the sampling distribution module. According to the scheme, the testing speed can be increased, and the cleaning liquid consumption is reduced.

Description

technical field [0001] The present invention generally relates to the technical field of medical equipment, and more specifically relates to a blood cell analyzer and a cleaning method thereof. Background technique [0002] At present, in the analysis of some five-class blood cells, in order to meet the needs of users for low sampling volume, a measurement system for micro blood measurement will be designed. The sample volume of the instrument is generally below 40 μL. , because the sampling needle has a certain volume, the sample is generally stored inside the sampling needle, and the sampling system divides the blood into each channel, and cleans the inside of the sampling needle after the blood is divided. [0003] With the continuous increase of clinical needs, more measurement modules are added to the five-differential blood cell analyzer to measure more parameters in an all-in-one machine; Integrated erythrocyte sedimentation measurement module, blood routine and eryt...

Problems solved by technology

[0004] In the ESR measurement mode, the sample is dragged to the inside of the rubber tube at the end of the sampling needle. Since the connection between the rubber tube and the tail of the sampling needle is prone to dead accumulation (that is, deposits that are not easy to be cleaned), it is difficult to clean, and the blood sample enters the rubber tube, and the sampling channel is blocked. The scope of blood sample contamination is relatively large. Compared with the blood routine measurement mode in which the sample is only in the needle, the cleaning of the sampling channel is more difficult. Generally, the amount of cleaning solution and the cleaning time will be increased to solve the problem. Such solutions will affect the performance of the instrument. measuring speed
