Description

Technical Field

[0001] The utility model relates to the technical field of cell centrifuges, in particular to a cell centrifuge for medical detection. Background Art

[0002] Medical testing is a medical tool used to evaluate and diagnose diseases. It obtains information about a patient's health status by collecting and analyzing samples. Common tests include blood tests and urine tests. A cytocentrifuge is a device used to separate, wash, and enrich cells. A cytocentrifuge is one of the commonly used devices in medical testing. It separates cell mixtures through centrifugal force. It has the advantages of high speed, high separation efficiency, and low damage. It is widely used in the fields of biology, medicine, and life sciences for cell processing. The working principle of a cytocentrifuge is based on centrifugal force. When the centrifuge is started, the centrifuge rotor begins to rotate. The components of different densities in the mixture are subjected to the centrifugal force and gravity and settle to the bottom or side of the centrifuge rotor. A cytocentrifuge usually has a variety of centrifugation programs and control parameters to meet different cell processing needs.

[0003] When using a cell centrifuge, test tubes containing cell mixtures are usually inserted into the centrifuge tank. However, it is inconvenient to fix the test tubes in the cell centrifuge, and the test tubes are prone to shaking and falling off, affecting the smooth progress of the centrifugation work. Therefore, improvement is urgently needed. Utility Model Content
