Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field especially relates to a blood collection tube shakes even device. BACKGROUND

[0002] Clinically, blood collection tubes are usually used to collect patient blood samples for testing, and after the sample collection is completed, the test tube needs to be manually inverted 360 degrees and mixed for 5-8 times to make the blood and the additives in the blood collection tube fully mixed. Insufficient mixing will affect subsequent testing and cause deviations in test results. Therefore, nurses who collect blood need to repeatedly shake the blood collection tube every day, which is a heavy workload. Moreover, a patient may need to extract multiple blood samples at a time, and the nurse needs to shake the blood collection tube while collecting the sample, which can easily distract the nurse and slow down the collection speed, resulting in a prolonged blood sample collection time. On the one hand, this can cause the patient to feel nervous, and on the other hand, the nurse's distraction can cause the blood sample to be shaken unevenly, resulting in unqualified blood samples and repeated collection. If multiple blood samples are collected and then shaken together, it can cause the blood to coagulate, resulting in unqualified blood samples. The automatic shaking device for preventing blood collection tube sample coagulation disclosed in the Chinese patent with the authorization announcement number CN221965093U drives the oscillating connecting piece to oscillate through the driving motor, and then drives the test tube rack to oscillate, realizing automatic shaking of the blood collection tube in the test tube rack. However, this device uses left and right shaking to mix, which is not the same as the 360-degree manual inversion mixing method used by nurses, and may result in insufficient mixing.
