After the test tubes are loaded, the rotating shaft is controlled to continuously rotate to drive the turntable to continuously rotate. And finally, the plurality of test tubes in the plurality of lifting baskets are driven to rotate for centrifugation. In the centrifugal process, the first annular plate moves up and down, the multiple lifting baskets can swing in a reciprocating mode relative to the rotary disc under pushing or pulling of the multiple connecting rods, and then the swing angles of the multiple test tubes are adjusted. Therefore, the swing angle of the test tube can be adjusted in the high-speed rotation process of the test tube, so that the centrifugal effect of reagents in the test tube is improved.

Description

Technical Field

[0001] The present application relates to the technical field of centrifuges, and in particular to a fully automatic upper and lower test tube medical centrifuge. Background Art

[0002] Medical centrifuge uses the centrifugal force generated by the rapid rotation of the turntable. The reagents in the test tubes follow the high-speed rotation of the turntable, thereby centrifuging the reagents.

During the centrifugation process, the first annular plate 7 is moved up and down, and under the push or pull of multiple connecting rods 8, the multiple baskets 6 can swing back and forth relative to the turntable 5, and then the swing angles of multiple test tubes can be adjusted.
