  • Apparatus for centrifugal separation of platelet-rich plasma
    Patent number: 4268393
    Abstract: This invention relates to an apparatus for separating platelets from blood samples by subjecting the blood sample to centrifugal force in the chamber while displacing the platelets from the blood sample by injecting a relatively small volume of saline into the centrifugally outer end of the chamber. In the preferred apparatus, the saline is injected into the blood sample by driving the chamber supporting the blood sample against a saline filled collapsible cavity under the influence of centrifugal force.
