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.
