A kind of preparation facilities of leucocyte-removing platelet rich plasma
Technical field
The utility model relates to blood plasma preparation, specifically a kind of preparation facilities of leucocyte-removing platelet rich plasma.
Background technique
Platelet rich plasma (Platelet rich plasma, PRP) is the blood platelet concentration that whole blood obtains after being centrifuged
Whether object contains leucocyte according in its ingredient, is roughly divided into the platelet rich plasma (L-PRP) of rich leucocyte and without white thin
The platelet rich plasma (P-PRP) of born of the same parents.A large amount of biologically active growth factors can be discharged after high concentration platelet activation, this
A little growth factors have great importance to Various Tissues reparation.Multiple studies have shown that PRP is can to slow down cartilage degeneration, together
When can promote regenerating bone or cartilage, have good application prospect in the treatment of osteoarthritis.And it is newest studies have shown that white thin
Born of the same parents and the few P-PRP of inflammatory factor are better than leucocyte and the higher L-PRP of inflammatory factor concentration to arthritic curative effect.
The principle of PRP is to carry out centrifugation preparation using the rate of settling difference of cell components different in blood, existing
The preparation method of mainstream is centrifugal process twice.However, the rate of settling of leucocyte and blood platelet is close in haemocyte, two after centrifugation
The distributed area of kind ingredient is very close, it is difficult to separate.Clinical obtained P-PRP is mostly weary leucocyte PRP, rather than truly
Leucocyte-removing PRP.
The PRP making apparatus of existing domestic and international application has more than ten, these equipment common configurations are complicated, and preparation cost is high,
And there is no leucocyte-removing is fundamentally realized, the clinical application of platelet rich plasma is limited.
Utility model content
Based on the above issues, the utility model implementation discloses a kind of preparation facilities of leucocyte-removing platelet rich plasma,
Solution can produce platelet rich, the high P-PRP of leukocyte depletion rate, can more effectively treat osteoarthritis, solution must not
The problem of obtaining PRP leucocyte-removing.
The utility model is to solve above-mentioned technical problem by following technical proposals:
A kind of preparation facilities of leucocyte-removing platelet rich plasma, which is characterized in that it includes filter, centrifuge tube, suction
Pipe and pipe lid are taken, the central symmetry protrusion of the filter top and bottom is equipped with incoming interface and outgoing interface, the centrifugation tube top
The outer rim in portion and pipe lid match, and the center on the centrifuge tube top is equipped with aperture, the aperture it is vertically cylindrical to
Upper extension, the aperture and outgoing interface match, and the center of the centrifuge tube is equipped with suction pipe, and the top of the suction pipe, which is equipped with, to be connected
Block is connect, the link block and aperture match.
Further, be equipped with screw thread on the outside of the outside of the outgoing interface, the inside of aperture and link block, it is described go out
It is connected through a screw thread between interface and aperture, between link block and aperture.
Further, the outside of the incoming interface is equipped with screw thread.
Further, the outer rim protrusion at the top of the centrifuge tube is equipped with screw thread, and internal screw thread is equipped on the inside of the pipe lid, described
Centrifuge tube is connected through a screw thread with Guan Gai.
Further, the caliber of the suction pipe is 0.5 ~ 1mm.
Further, the bottom shape of the centrifuge tube is back taper.
The positive effect of the utility model is: increasing filter for removing white blood cell, more efficiently goes whole blood white thin
Born of the same parentsization reduce leucocyte and the possible adverse effect of the related inflammatory factor, while removal one polymers or microtissue slightly
Clast improves the storage quality of blood platelet;Structure is simple, can reduce the financial burden of patient;Preparation process operates convenient, mistake
The processes such as filter, centrifugation, absorption are completed under closed environment, are effectively reduced and are contacted with external environments such as air, avoid bacterium to disease
The pollution of poison, can be improved the service efficiency of blood platelet.

Specific embodiment
Below with reference to examples and drawings, the utility model is described in further detail, but the reality of the utility model
The mode of applying is not limited only to this.
The utility model is intended to provide a kind of preparation facilities of leucocyte-removing platelet rich plasma, which is characterized in that it is wrapped
Include filter 1, centrifuge tube 2, suction pipe 3 and pipe lid 7, the filter 1 is used for filtrating leukocytes, inside the filter 1
Filter membrane is made of the hydrophilic biomaterial of multilayer, and leucocyte-removing filtration rate is in 95% or more, 1 top and bottom of filter
The symmetrical protrusion in centre is equipped with incoming interface 4 and outgoing interface 5, and the incoming interface 4 and outgoing interface 5 are located at the upper and lower ends of filter 1,
The outer rim and pipe lid 7 at 2 top of centrifuge tube match, and the center on 2 top of centrifuge tube is equipped with aperture 6, and the aperture 6 is along vertical
Histogram is upwardly extended to cylindrical, and the aperture 6 matches with outgoing interface 5, and the center of the centrifuge tube 2 is equipped with suction pipe 3, institute
The top for stating suction pipe 3 is equipped with link block 301, and the link block 301 matches with aperture 6.
When it is implemented, the outside in the outside of the outgoing interface 5, the inside of aperture 6 and link block 301 is equipped with spiral shell
