Automated sample pretreatment system

Abstract

The invention discloses an automatic sample pretreatment system which comprises a mounting frame, and a horizontal conveying mechanism, a clamping mechanism, a safety protection mechanism, a vertical lifting mechanism, a weighing and filling mechanism, a sample frame transmission device, a mixing device, an automatic cover opening and closing transfer mechanism and a bar code scanner are arranged on the mounting frame. According to the invention, the whole-support or single-support automatic sample injection of a sample can be realized, and the sample can be added at any time in the sample injection process, so that the operation flexibility of medical personnel is improved; transferring, weighing, filling, uniform mixing and sample adding of samples can be achieved, and the pretreatment efficiency and consistency are improved; in the filling process, standardized addition can be performed according to a weighing result, so that errors caused by manual sample size evaluation are effectively solved, and the sample digestion effect is improved; and by adopting the uniform mixing device capable of improving the homogenization treatment effect of the non-liquid sample, the uniform mixing effect is enhanced.

Description

technical field [0001] The invention relates to the technical field of automatic detection equipment, in particular to an automatic sample pretreatment system. Background technique [0002] With the rapid development of the national economy and the improvement of the entire laboratory medical technology, in clinical applications, samples are mainly processed manually. During this process, medical personnel directly contact the samples, which may cause infection and cause personnel to be infected with germs; at the same time , when encountering a viscous sample, the lid is usually opened and closed manually, the sample is filled with reagent solution and then mixed, and then tested after the sample is liquefied, but the amount of reagent solution added is completely dependent on manual completion. It is greatly affected by human factors, and it is difficult to grasp the uniformity and standardization; the operation time is long and the effect is not ideal; at the same time, m...

[0002] With the rapid development of the national economy and the improvement of the entire laboratory medical technology, in clinical applications, samples are mainly processed manually. During this process, medical personnel directly contact the samples, which may cause infection and cause personnel to be infected with germs; at the same time , when encountering a viscous sample, the lid is usually opened and closed manually, the sample is filled with reagent solution and then mixed, and then tested after the sample is liquefied, but the amount of reagent solution added is completely dependent on manual completion. It is greatly affected by human factors, and it is difficult to grasp the uniformity and standardization; the operation time is long and the effect is not ideal; at the same time, manual operation has shortcomings such as low detection efficiency, long operation time, sample cross-contamination, and uneven sample processing. It cannot meet the increasing demand for patient samples and testing, so there is an urgent need for a safe, effective, fully automatic sample pretreatment system device
