[0002] Capillary blood collection mainly includes two methods: earlobe blood collection and fingertip blood collection. When collecting blood from the capillaries of infants and young children, the collected blood needs to be injected into a blood collection tube, and then the bottom of the blood collection tube is flicked with a finger or the blood collection tube is shaken to achieve the purpose of mixing the blood and fully mixing the anticoagulant on the inner wall of the blood collection tube;

[0003] However, after blood collection with the existing blood collection tubes, the internal medicine is prone to deposition. It is necessary to shake the blood in the blood collection tube to fully mix the blood with the anticoagulant on the inner wall of the tube body, so as to avoid the deposition of the medicine. However, in actual operation, the mixing effect by shaking is not good, and long-term shaking is easy to cause fatigue of the operator's arm; Therefore, it does not meet the existing needs, and for this reason, we propose an adjustable-angle micro blood collection tube stent. Content of the Utility Model
