Liquid feeding missing and liquid sucking missing detection apapratus

Abstract

A purpose of the present invention is to provide a liquid feeding missing and liquid sucking missing detection apparatus, which comprises a control plate, a box-like base, a weighing sensor and a sensing plate, wherein the control plate is provided with COM, USB and IP communication interfaces and is arranged on the upper surface in the box-like base, the right side of the control plate is provided with the weighing sensor, the upper end surface of the box-like base is provided with the sensing plate, and the lower end surface of the sensing plate contacts the weighing sensor to achieve the sensing of the weight change. With the technical scheme of the present invention, the liquid container weight changes at the liquid sucking position and the liquid feeding position are automatically detected, such that the personnel is timely reminded to find the problem or the user is linked by using the COM, USB and IP communication interfaces to apply the software to pause the experiment so as to avoid medical risks caused by negligence, eliminate the personnel monitoring cost, reduce the waste of the material, and improve the reliability and the safety of the automated medical device.

Description

technical field [0001] The invention relates to a medical automatic experiment equipment, in particular to a device for automatically detecting the leakage of liquid addition and suction in the process of liquid distribution. Background technique [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 fails 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. Add liquid. At present, in order to identify leakage of liquid addition and leakage of suction, it mainly...

[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.
