Description

Technical Field

[0001] The utility model relates to the field of laboratory technical equipment, in particular to a blood collection tube mixing and shaking device. Background Art

[0002] At present, after collecting blood from patients in hospitals, the blood is usually temporarily stored in an independent blood collection tube, and then the blood sample is manually shaken by medical staff to fully mix the blood sample with the anticoagulant in the blood collection tube. Insufficient mixing will cause blood clots, which will affect subsequent tests and cause deviations in test results. Therefore, nurses who usually collect blood need to repeatedly shake the blood collection tube every day, causing physical and mental fatigue.

[0003] Existing patent technology CN202221830162.4 discloses an automatic mixer for anticoagulant blood collection tubes, including a base and a support plate, the support plate is fixed to the top of the base, a fixed shaft is fixed to the top of the support plate, a sun gear is fixed to one end of the fixed shaft, a plurality of planetary gears are meshed on the outer side of the sun gear, a same planetary frame is fixed to one end of the central shafts of the plurality of planetary gears, and a fixed disk is fixed to the other end of the central shafts of the plurality of planetary gears. The utility model adopts an electrically driven shaking method through the coordinated use of the designed fixed shaft, sun gear, planetary gear, planetary frame, fixed disk, clamping assembly and rotating parts, so as to fully mix the blood sample with the anticoagulant in the blood collection tube, and can fully shake a plurality of blood collection tubes, thereby reducing labor intensity and improving mixing efficiency.

[0004] Although the mixer mentioned in this patent can mix multiple blood collection tubes, improving the mixing efficiency. However, the mixing method uses the blood collection tube itself to rotate around the central axis for mixing, which does not simulate the upside-down mixing method performed by the nurse after blood collection, which may cause the blood to not fully contact the anticoagulant at the mouth of the blood collection tube. Therefore, we intend to propose a blood collection tube mixing device that can simulate the upside-down mixing of the nurse's arm to improve the mixing effect. Utility Model Content
