Leave the blood platelet of centre and the blood plasma on upper strata；
2.3 put protective cap 15 again, will extract suit and be placed in second centrifugation is carried out in centrifuge, after centrifugation is finished, take
Go out extraction element, remove protective cap 15, suit will be extracted and gently promote the second syringe 12 vertically downward, drive first piston 21 to
Lower movement, by red blood cell extrusion remaining in the first syringe 11；
3）Detach extraction
After removal red blood cell, push rod 14 is vertically gently pulled, drive the 3rd piston 23 to move up, lived by through first
Fill in the flexible pipe 25 of 21 axial faces and will be located at the blood platelet of lower floor in the first syringe 11 and suck in the second syringe 12, needed for obtaining final product us
Platelet rich plasma, and the blood plasma stayed in the first syringe 11 pushed away by gently promoting the second syringe 12.
4）Install and use
When platelet rich plasma is used, the second syringe 12 is screwed out from the first syringe 11, remove first piston 21, the
Injection needle 162 or spraying nozzle are installed on the interface of the leading section of two syringe 12 can be used wound.
Herein, in order to prevent in centrifugal process, the first syringe 11 is separated with the second syringe 12.In the present embodiment,
Extraction suit is also included located at the locking mechanism locked for both between the first syringe 11 and the second syringe 12.The locking machine
Structure is including the stop part 111 with draw-in groove 112 in the rearward end of the first syringe 11, in the outer peripheral sidewall of the second syringe 12
Lug boss 121, as shown in fig. 6, the lug boss 121 is engaged with the size of draw-in groove 112, when the lug boss 121 is located at draw-in groove 112
Length bearing of trend on when, the locking mechanism unblock, the second syringe 12 can be along the interior wall slip of the first syringe 11；Work as lug boss
During the length bearing of trend of 121 deviation draw-in grooves 112, locking mechanism locking, the second syringe 12 is still plugged in the first syringe 11
Rearward end on, for the ease of lug boss 121 be aligned draw-in groove 112, be labeled with the lateral wall of first syringe 11 ON instruction
Line, the length bearing of trend of the instruction line is consistent with the length bearing of trend of the draw-in groove 112.Specifically, working as, centrifugation behaviour need to be carried out
When making, then the second syringe 12 is rotated, the lug boss 121 in the outer peripheral sidewall of the second syringe 12 is deviateed on the lateral wall of the first syringe 11
ON instruction lines, lock locking mechanism；After centrifugation terminates, when need to carry out draw operation to the second syringe 12, then is rotated
Two syringes 12, make the lug boss 121 in the outer peripheral sidewall of the second syringe 12 be directed at ON instruction lines.
Embodiment 2
The difference part of the present embodiment and embodiment 1 is that increased the 3rd syringe 13 in the present embodiment and go white thin
Born of the same parents' filter 24, so that can further by Impurity removals such as the leucocyte in blood platelet, some microtissue chips and micro- polymers.
In the present embodiment, referring to shown in Fig. 3, Fig. 4, extraction suit also includes the 3rd syringe 13, and push rod 14 is plugged in the
Can slide in the rearward end of three syringes 13 and along the inner wall sealing of the 3rd syringe 13, the 3rd syringe 13 can slide along the longitudinal direction
Be plugged in the rearward end of the second syringe 12.Herein, likewise, being arranged with the 3rd piston on the leading section of push rod 14
23, the 3rd piston 23 mutually seals setting with the inwall of the 3rd syringe 13.It is arranged with the leading section of the 3rd syringe 13 and
The inwall of two syringes 12 mutually seals the second piston 22 of setting, and the second piston 22 has hollow inner chamber, and extraction suit is also
Including the filter for removing white blood cell 24 in the inner chamber of second piston 22, offered on the axial forward end face of the second piston 22
The piston hole communicated with its own inner chamber.In order to ensure the fastness of connection, 22 points of the filter for removing white blood cell 24, second piston
It is not threadedly coupled mutually with the 3rd syringe 13.Herein, it also is provided with externally threaded interface on the leading section of the 3rd syringe 13, should
Filter for removing white blood cell 24 is mutually threadedly coupled with the interface.
In the present embodiment, be provided with the filter membrane for leukocyte depletion in the filter for removing white blood cell 24, the filter membrane be by
Have what hydrophilic melt-blown fine resin fabric nonwoven cloth was laminated after the modified treatment of multilayer, wherein, every layer of non-woven fabrics
Fiber string diameter be 6.25-25 μm, non-woven fabrics aperture be 15-60 μm.Herein, PBT or PET resin fiber is can select to prepare
Above-mentioned non-woven fabrics.The filter membrane being made of above-mentioned material, its filtering accuracy is high.Blood platelet after the filter membrane, as removes
The platelet rich plasma of the impurity such as leucocyte, some microtissue chips and micro- polymers.
It is red eliminating on the basis of embodiment 1 during the extraction of the present embodiment is sleeved on extraction rich platelet
After cell, the 3rd syringe 13 is pulled, the blood platelet in the first syringe 11 is pumped to in the second syringe 12 by flexible pipe 25, and
The second syringe 12 is promoted to extrude unnecessary blood plasma afterwards, then pull push rod 14, makes the blood platelet in the second syringe 12 through second
It is pumped in the 3rd syringe 13 after piston 22, filter for removing white blood cell 24, now, the blood platelet in the 3rd syringe 13 is and removes
The platelet rich plasma of the impurity such as leucocyte.When using, the 3rd syringe 13 is screwed out from the second syringe 12, screw out second and live
Plug 22 and filter for removing white blood cell 24, install injection needle 162 or spraying nozzle on the leading section interface of the 3rd syringe 13
Wound is used.
To sum up, the extraction suit of platelet rich plasma of the invention, from taking a blood sample, being centrifuged to the whole of platelet rich plasma is obtained
It is to be completed in closed system during individual, efficiently avoid in the prior art, is extracting platelet rich plasma when institute
The pollution problem being likely encountered, the red blood cell of lower floor and the blood plasma on upper strata go after pull syringe will can be layered in blood
Remove, obtain platelet rich plasma, and pass through to increase filter for removing white blood cell 24, can by leucocyte in platelet rich plasma etc. its
His some Impurity removals, obtain eliminating the platelet rich plasma of leucocyte, efficiently avoid white thin in use
The complication that born of the same parents are brought.
The above embodiments merely illustrate the technical concept and features of the present invention, its object is to allow person skilled in the art
Scholar will appreciate that present disclosure and be carried out that it is not intended to limit the scope of the present invention, all according to the present invention
