Description

Technical Field

[0002] Clinical testing is the testing of materials taken from the human body in the fields of microbiology, immunology, biochemistry, genetics, hematology, biophysics, cytology, etc. In the routine, physiological, and biochemical testing operations of clinical testing, reagents, buffers, and test samples are often required to be diluted by adding liquid before processing and testing. In the operation of adding liquid and diluting, the manual dilution operation of the inspector has large errors, and it is not convenient to stir and dilute the diluent, which has a negative impact on clinical testing work. Therefore, some automatic stirring diluents have appeared on the market.

[0003] For example, the patent document with the publication number CN212942410U discloses a "liquid adding diluter for medical testing", which can drive the stirring component to rotate by a motor to stir the diluent, replacing the manual stirring of the diluent, reducing the workload of the experimenter, and can add different reagents to the holding cup by rotating the turntable, which can not only avoid cross infection between reagents, but also bring convenience to the user. However, there are some problems with this scheme: on the one hand, when a smaller-sized holding cup is placed in the groove of the base, the flow of liquid during stirring makes the holding cup easy to shake in the groove, and the scheme directly sets a motor in the cavity at the bottom of the holding cup, and the motor drives the stirring component to stir in the holding cup. The vibration of the motor is easy to damage the holding cup, and even if there is a sealant, it is easy to leak; on the other hand, for some poorly soluble reagents or reagents that need to be heated, the liquid adding and dilution effect of this scheme is poor.
