In order to ensure the storage of blood in a blood bank, various blood sampling and donation activities enter the living environment of people, a blood sampling mixer is often used in the blood sampling, because coagulation factors exist in the blood, after the blood leaves a human body, if anticoagulant preservation solution and the blood cannot be fully fused, the collected blood cannot be used, and the waste and the economic loss of the blood are caused, so that medical workers use machines or shake blood bags manually when collecting the blood to mix the preservation solution and the blood, but the manual operation is easy to generate fatigue, most of the swing modes of the machines are left and right inclined, the comprehensive shaking mixing cannot be completely carried out, and the liquid mixing effect cannot achieve the effect of the manual operation.

In addition, when collecting a platelet product, platelets aggregate in the centrifuge bag due to the relatively high centrifuge speed of the apparatus, and therefore, it is necessary to manually perform the shaking depolymerization. The strength and frequency of the oscillation are determined according to the specific conditions of the amount of collected materials, the size of the container and the like, and certain experience is needed to be sufficient. Insufficient depolymerization can occur when the vibration force is insufficient; the platelet can be accumulated again when the manual shaking force is too large, so that the platelet is inactivated, and precious platelet resources are wasted. However, the effect of the oscillation is greatly related to the manipulation and skill of the operator, which eventually causes the oscillation effect to be uneven, and is not suitable for standardization.

There are the equipment that the depolymerization was vibrate to a small part, adopt inverter motor to change dynamics, range and the frequency of rocking, but output power need frequently be changed to motor itself, and control is comparatively troublesome, and frequent variable power is great to motor loss own, even after changing the frequency, its dynamics, range and the frequency of vibrating also are fixed, can not simulate the people hand completely and rock, and it is all unfavorable to vibrate depolymerization or different component mixes.
