Centrifugal device for medical science inspection

Technical Field

The utility model relates to the technical field of centrifugal devices, in particular to a centrifugal device for medical examination.

Background

Centrifuges are machines that utilize centrifugal force to separate components of a liquid from solid particles or a mixture of liquid and liquid. Centrifuges are mainly used to separate solid particles from liquids in suspension or to separate liquids of different densities and which are not mutually compatible with each other in emulsions (e.g. to separate cream from milk); it can also be used to remove liquids from wet solids, such as drying wet clothing with a washing machine; the special overspeed tube separator can also separate gas mixtures with different densities; by utilizing the characteristic that the sedimentation speeds of solid particles with different densities or particle sizes in liquid are different, some sedimentation centrifuges can also classify the solid particles according to the densities or particle sizes.

For example, chinese patent publication No. CN213494320U discloses a centrifugal device for medical examination. Through setting up the second motor, when the staff uses the device to carry out the in-process of centrifugal operation to the medicine, the staff only need start the second motor through control switch, under the cooperation of first gear and second gear, can make the second pivot drive the standing groove and rotate to the purpose of carrying out centrifugal operation to the medicine has been reached. However, during the centrifugation, the medicine is too close to the rotating shaft, and the farther from the rotating shaft, the larger the centrifugal force is, whereas the smaller the centrifugal force is, which may cause poor separation effect on the sample during the centrifugation, and is not beneficial to medical examination; in view of this, we propose a centrifugal device for medical examination.
