Fully-automatic blood extraction centrifuging device and extraction centrifuging method thereof

Abstract

The invention discloses a fully-automatic blood extraction centrifuging device and an extraction centrifuging method thereof. Before operation such as a blood cross-matching test is conducted in a hospital or a laboratory, currently, medical care personnel or test personnel need to transfer to-be-tested blood in sample tubes into test tubes, then the blood is centrifuged, and therefore operation is cumbersome. The fully-automatic blood extraction centrifuging device comprises a rack, a lifting-type centrifuging mechanism, a blood vessel clamping mechanism, a cutting mechanism, a tool storage mechanism and a tool transport mechanism; the tool storage mechanism comprises a circular tool disc, a tool disc rotating shaft, a tool disc driving motor, a fixed pushing block, a tool storage rack and a first reset spring; and the cutting mechanism comprises a cutting rotating shaft, a rotating motor, a rotary cantilever, a tool box assembly, a tool box driving assembly and a tool box sliding block. The blood in the sample tubes is transferred into the test tubes on a centrifuging rotating disc through instrument automation, blood centrifuging required before blood cross-matching is conducted, and previous complex operation is replaced.

Description

technical field [0001] The invention belongs to the technical field of blood extraction and centrifugation, and in particular relates to an automatic blood extraction centrifugation device and an extraction centrifugation method thereof. Background technique [0002] With the rapid development of medical technology, blood group analysis has become an important part of clinical medicine. Blood transfusion therapy has become one of the important means in the treatment of clinical diseases. Cross-matching blood is one of the essential steps in blood group analysis. Before performing cross-matching blood tests in hospitals or laboratories, it is currently necessary for medical staff or test personnel to be tested The blood in the sample tube is transferred to the test tube, and it is centrifuged, and the operation is relatively cumbersome. In addition, at present, scissors are generally used to unseal the sample tube, which greatly increases the blood contamination in the sampl...
