A centrifuge rotor

Abstract

The invention relates to a rotor of a centrifuge, comprising: a centrifugal turntable, which is composed of a base plate and a saw-shaped ring. A plurality of clamping positions are evenly distributed around the base plate; , there is an ejection bayonet at the position aligned with the middle of the card position on the baffle, and a card ejection baffle is arranged on the inner side of the empty slot, and the saw-shaped ring is fixed on the circumference of the chassis by screws; the upper card module is located in the card position The upper part of the card is provided with a first opening and a sliding door, and the sliding door is used to open or close the first opening; the card ejecting module, located outside the ejecting slot, includes an electromagnet and a push-pull rod, which is used to remove the card position through the ejecting slot. The reagent card on the top is ejected. In the embodiment of the present invention, the method of loading and ejecting the reagent card is improved by the improved centrifugal turntable, so as to prevent the reagent card on the card position from flying out during centrifugation and the phenomenon that the reagent card is stuck during the ejection, thereby damaging the centrifugal turntable.

Description

technical field [0001] The invention relates to the technical field of centrifugal detection, in particular to a rotor of a centrifuge. Background technique [0002] With the rapid development of biological engineering technology in the world, the detection and identification methods for cross-matching blood, blood type and antibodies have gradually changed from the traditional blood type serological routine detection to the microcolumn gel immunodetection technology. The microcolumn gel immunoassay method must be equipped with a microcolumn reagent card. During detection, blood is added to the reagent card, and the reagent card is placed on the centrifugal turntable of the centrifuge, and the reagent is fully combined with the blood through centrifugation to obtain the result. At present, when the reagent card is installed in the centrifugal turntable of the centrifuge, the reagent card is usually pushed in from the outside of the centrifugal turntable and the reagent card...

AI Technical Summary

Problems solved by technology

At present, when installing the reagent card on the centrifugal turntable of the centrifuge, the reagent card is usually pushed in from the outside of the centrifugal turntable and fixed by the buckle. When the buckle is not fastened or loose, the reagent card will fall off. At the same time, when the card is automatically returned, there will also be a phenomenon that the card cannot be returned due to the buckle being too tight and the centrifugal turntable will be damaged.
