Problems solved by technology

[0002] At present, automated experimental equipment is widely used in the field of medical inspection. In the process of automated experiments, the common liquid distribution method is to use a combination of pumps and sampling needles. In the actual experimental process, due to pump failures, control software failures, and artificial settings Due to various reasons, such as the deviation of the suction position, the pump will fail to suck the liquid into the sample needle for transfer during the liquid transfer process. When the sample needle moves to the position where the sample needs to be added, it will further cause leakage. Adding liquid. At present, in order to identify leakage of liquid addition and leakage of suction, it mainly relies on manual monitoring during the process or identification afterwards. The main problem of using manual monitoring during the process is that the labor cost is high, and personnel are prone to negligence and mistakes, especially when the amount of moving liquid is large. In small cases, it is often extremely difficult for personnel to identify errors. The main problem of using post-identification methods is the waste of samples, reagents and time, and the cost is very high. Once the leakage of liquid addition cannot be identified in time, wrong test results will occur and cause medical risks.
