Description

TECHNICAL FIELD

[0002] Blood detection is the most general, basic and common detection method in medical detection. Blood detection is beneficial to early discovery of potential pathological changes, prediction, screening and indication of hundreds of diseases such as severe infection, cardiovascular and cerebrovascular diseases, malignant tumors, metabolic imbalance and damaged organs, and is a simple and fast health examination.

[0003] In order to avoid blood coagulation within a short time after being drawn out of the human body, the blood is placed in a prepared test tube and shaken to uniformly mix the reserved anticoagulant in the test tube with the blood, so as to prolong the blood coagulation time and avoid affecting the blood detection result.

[0004] In the prior art, medical staff draws the blood of a patient into a blood collection bottle, shakes the blood collection bottle by hand to mix the blood of the patient with the anticoagulant in the blood collection bottle, and avoids blood coagulation from affecting the accuracy of the detection result. However, the medical staff not only cannot uniformly mix the blood and the anticoagulant by shaking the blood collection bottle by hand, but also increases the workload of the medical staff. If the detection needs to be queued and the waiting time is relatively long, the blood collection bottle also needs to be placed in a special refrigerator for cold storage. However, the blood oscillation device commonly used in the prior art adopts a horizontal reciprocating oscillation mode when oscillating the blood test tube. However, the reciprocating oscillation of the test tube in a single direction cannot uniformly mix the blood cells in each layer in the test tube.
