Platelet-rich plasma preparation device

The invention provides a platelet-rich plasma preparation device, and relates to the technical field of medical instruments.The platelet-rich plasma preparation device comprises a plasma preparation device body, the plasma preparation device body comprises an upper end cover and a lower base, and a centrifugal bin, a filtering column and a receiving pipe are arranged between the upper end cover and the lower base; a separation column is arranged in the centrifugal bin, and a suction hole is formed in the separation column; the upper end of the filter column is communicated with the upper end of the receiving pipe, and the lower end of the receiving pipe is connected with the second interface. According to the platelet-rich plasma preparation device provided by the invention, the preparation time is shortened, the action of shear force is reduced, the activation and aggregation probability of platelets is reduced through one-time centrifugation, excessive moisture and small molecular substances are removed in
