1. a blood rich platelet separating and extracting process, is characterized in that:

  • have separating extraction device, and the structure of this separating extraction device is;

    Comprise PRP locker room (1) from top to bottom, blood plasma locker room (2), PRP/ red blood cell securing rod swing handle (3) and red blood cell locker room (4), described blood plasma locker room (2) is threaded with PRP locker room (1) and PRP/ red blood cell securing rod swing handle (3) respectively, and threaded connection place is provided with silica gel sealing ring (5), PRP/ red blood cell securing rod swing handle (3) and red blood cell locker room (4) fixed seal connection, junction is communicated with by blood plasma entrance hole (3-1), the serum entrance hole (1-1) of a taper is also provided with between PRP locker room (1) and blood plasma locker room (2), in described blood plasma locker room, (2) are also provided with a PRP securing rod (2-1), this PRP securing rod (2-1) is fixedly connected with blood plasma locker room (2) and follows it and moves, and this PRP securing rod (2-1) runs through the space between serum entrance hole (1-1) and blood plasma entrance hole (3-1) from top to bottom successively, the two ends caliber size of described PRP securing rod (2-1) coincide with the aperture size of described serum entrance hole (1-1) and blood plasma entrance hole (3-1) respectively, the space up and down of isolation corresponding entrance hole can be closed when PRP securing rod (2-1) is entered in corresponding entrance hole, described PRP locker room (1) and red blood cell locker room (4) have all been threaded connection lid, threaded connection place is sealed by silica gel sealing ring,In the lid of described PRP locker room (1), sealing is provided with silica gel plug (6) and is coated with protection foil film on silica gel plug (6);

    The sidewall of described blood plasma locker room (2) is provided with two symmetrical holes;

    one is blood hand-hole (7);

    another is filter ventilation hole (8);

    described blood hand-hole (7) is injected with a plug by double-colored pair of material;

    filter ventilation hole (8) is pressed with a ventilative resistance mycoderm by silica gel pressure ring, and is provided with a dismountable Capsule;

    Concrete steps are;

    A, use injector for medical purpose venous blood samples, this device is upright, the Capsule of filter ventilation hole (8) is opened, and piercing through silica gel plug injection venous blood in blood plasma locker room (2) from blood hand-hole (7), blood flows into red blood cell locker room (4) by blood plasma locker room (2);

    B, the ACD that simultaneously gets ?A anti-coagulants, anti-coagulants and blood ratios 1;

    10, injected by blood hand-hole (7), closes filter ventilation hole (8);

    C, this device is put in centrifuge, blood will layering, lower floor'"'"'s liquid level is red blood cell, top liquid level is serum, the lid of red blood cell locker room (4) is regulated to regulate above the closed place of blood plasma entrance hole (3 ?1) by top serum, in order to ensure that red blood cell does not infiltrate serum, stay the serum liquid level of 2mm ?3mm height in the below at the closed place of blood plasma entrance hole (3 ?1), rotation PRP/ red blood cell securing rod swing handle (3) makes PRP securing rod (2 ?1) enter blood plasma entrance hole (3 ?1) and makes its closed isolation;

    D, this device to be inverted, the serum layer isolated is entered PRP locker room (1) by the hollow hole of blood plasma locker room (2);

    E, this device is put on centrifuge centrifugal, blood will layering, bottom is platelet cell, top is impurity layer, regulate the lid of PRP locker room (1), on the serum entrance hole (1 ?the

         1) impurity layer on top being adjusted to PRP locker room (1), in order to ensure that free from admixture is referred and synthesized, simultaneously by 2mm ?the platelet cell layer of 3mm liquid level be also modulated on serum entrance hole (1 ?1), then PRP securing rod (2 ?1) is adjusted to taper hole and closes and cut off;

    F, tear the protection foil film of the tops of PRP locker room 1 off, injector for medical purpose is thrust silica gel plug (6) to PRP locker room (1), extract platelet rich plasma for subsequent use.
