Problems solved by technology
[0002] The blood cell analyzer is a medical precision instrument, which is used to measure the relevant information of blood cells. During use, the system is prone to waste liquid impurities or residual protein accumulation, which may cause internal blockage of the instrument system or inaccurate measurement results. Therefore, it needs to be checked every day. and regular maintenance
In the case that general maintenance cannot solve the problem, it is necessary to soak and clean the system with a strong cleaning solution. Because of its strong corrosiveness and high price, the consumption of strong cleaning solution is relatively small, and it is not suitable for long pipeline transportation to avoid waste. Let it flow directly through the solenoid valve. Long-term contact will easily corrode the internal components of the solenoid valve. It is also impossible to open the liquid bottle containing a strong cleaning solution into the machine or use a sampling needle to puncture the cover for automatic distribution. The mouth or puncture is easy to volatilize and crystallize the powerful cleaning solution and corrode the internal structure of the instrument
Therefore, the current method is to manually lift the bottle and place it under the sampling needle outside the machine to absorb the powerful cleaning solution several times to realize the function of soaking and cleaning. Soaking and cleaning operation, because the entire shutdown process of the instrument takes a long time, if a person is on duty to add liquid, it is more troublesome and wastes manpower, resulting in a bad user experience
