The autologous platelet concentration filter mainly filters the blood platelets to selectively capture the platelets in the blood,re-releases the platelets captured by the membrane through the secondary extraction method. The main principle comes from the control of membrane holesmembrane. The surface modification technology, multi-layer laminated membranethe control of the extraction design make it possible to quickly obtain autologous platelets concentrated.

The main purpose of this invention is to provide a training system with the surrounding photographing unit, the display unit,a force platform. The system can immediately capture the motion of the user from various angles,measure the force of the user from both legs, in order to provide the useful biofeedback information to coachesathletes.
