Dynamic observation device and method for centrifugal machine

Abstract

The invention relates to the technical field of blood component treatment, and discloses a dynamic observation device and method for a centrifugal machine. The device comprises an image collector, a light source, a bucket, a rotor position sensor, and a stroboscopic trigger module. The invention further discloses a dynamic observation method for the centrifugal machine. The dynamic observation method comprises the following steps that: S1, the centrifugal machine operates; S2, the rotor position sensor generates an angle position signal and transmits the angle position signal to the stroboscopic trigger module, and the stroboscopic trigger module switches on the light source once; S3, the image collector collects an instantaneous picture of a transparent centrifugal tube; S4, the image collector transmits the instantaneous picture to a display; and S5, the instantaneous picture is observed by naked eyes, and the centrifugal state of a sample is judged. The stroboscopic trigger module triggers the light source to supplement light for the image collector, so that the image collector can capture a clear instantaneous picture of the transparent centrifuge tube, and an operator can judge the centrifugation progress of the blood sample conveniently.

Description

technical field [0001] The invention relates to the technical field of blood component processing, in particular to a dynamic observation device and method for a centrifuge. Background technique [0002] The current cell technology has been developed rapidly, and the research and application of cell technology still has a lot of space. A necessary step in the research and application of cell technology is the acquisition of stem cells or immune cells. For example, umbilical cord blood stem cells and peripheral blood mononuclear cells are obtained by centrifugal separation of umbilical cord blood or peripheral blood. The quality and efficiency of centrifugal separation directly affect the results of related research work and applications. [0003] The quality of blood centrifugation is affected by many aspects of the centrifugal factor of the centrifuge. Generally, the more stable the centrifuge is running, the more appropriate the centrifugal force is, and controlling the...

AI Technical Summary

Problems solved by technology

In reality, the separation factor used in the same blood separation operation specification is often invariable, and there are individual differences in the source of blood samples, which leads to the fact that the empirical separation factor cannot be well adapted to the existing Different sources of individual blood samples, resulting in poor quality of some blood separation and even waste of blood samples

[0004] At present, the centrifuge is at a relatively high speed during the centrifuge operation, and the high-speed moving centrifuge tube and the blood sample in the centrifuge tube cannot be directly observed

Under normal circumstances, there is only one way to know whether the centrifuge work is completed, and that is to stop the centrifuge. However, starting and stopping the centrifuge is generally slow and stable to facilitate the stratification of components, which is bound to be time-consuming and cumbersome.

However, the change of the blood sample in the centrifuge tube by the operator during the period of starting and stopping of the centrifuge cannot be observed.
