Description

Trace blood stirrer for medical blood assay

Technical Field

The invention relates to the technical field of medical instruments, in particular to a micro blood stirrer for medical blood assay.

Background

The stirrer is a device for forcing convection and uniform mixing of liquid and gas media. The type, size and speed of rotation of the stirrer all have an effect on the distribution of the stirring power between bulk flow and turbulent pulsation. In general, the power distribution of a turbine-type agitator is favorable for turbulent pulsation, while a propeller-type agitator is favorable for bulk flow. For the same type of stirrer, under the same power consumption condition, the power of the stirrer with large diameter and low rotating speed is mainly consumed in the overall flow, so that the macroscopic mixing is facilitated. The power of the small-diameter high-rotation-speed stirrer is mainly consumed by turbulent pulsation, so that micromixing is facilitated.

At present, after the existing medical micro blood stirrer is used, the stirrer needs to be sterilized and then can be used again, and the method can reduce the working efficiency of the medical micro blood stirrer, so that the invention of the micro blood stirrer for medical blood test is necessary to solve the problems.
