Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of test sample mixers, and more particularly to an intelligent medical test sample mixer. BACKGROUND

[0002] The medical test sample mixer is a device for effectively mixing medical test samples, and belongs to the medical test field. It is mainly used to ensure the homogenization of samples during testing. Through automatic and standardized operation, the working efficiency and quality of the laboratory can be effectively improved. In medical testing, sample mixing is a basic and tedious process. Traditional manual mixing requires manual operation by the tester, which is not only slow, but also inefficient when dealing with a large number of samples. The intelligent medical test sample mixer can automatically complete the mixing of samples and operate quickly and accurately according to the preset program, greatly shortening the sample mixing time.

[0003] A medical test sample mixing method is disclosed in Chinese Patent No. CN101718649A. The method includes the steps of adding a sample and a diluent into the same container and mixing the sample and the diluent. The mixing step includes pressing the mixed liquid in the same container to another mixing container under certain pressure conditions. The method can achieve uniform mixing by using certain pressure to make the mixed liquid produce a vortex-like spiral flow. The method can realize automatic mixing through mechanical control, improve the mixing effect by controlling pressure and other conditions, and achieve consistent operation. The method can realize the automation of an important step in the pre-treatment of test samples.

The existing mixers used in experiments can only process a single group of experimental objects, resulting in a time difference between the front and rear samples. It is impossible to accurately synchronize the comparison data of multiple samples, and the existing experimental process is to immerse and clean the test tubes one by one, which causes a time difference in the cleaning of subsequent test tubes, resulting in the risk of drying and solidification during the cleaning of subsequent test tubes.
