Platelet rich plasma (platelet-rich plasma, PRP) is the blood platelet that fresh whole blood is extracted after centrifugation
The blood plasma that 4~5 times higher than platelet content in normal whole blood of content.
1984, Assoian etc. had found that wherein Platelet alpha granule is releasable after the PRP extracted in human plasma, Activation In Vitro
A variety of growth factors, such as：Platelet derived growth factor (platelet-derived growthfactor, PDGF), conversion life
The long factor-β (transforming growth factor, TGF-β), VEGF (vascular
Endothelial growth factor, VEGF), EGF (vascularendothelial growth
Factor, EGF), para-insulin like growth factor (insulin-like growthfactor, IGF), fibroblastic growth
Factor (fibroblast growth factor, FGF) etc..They are mixed with natural ratio, play synergy.Wherein
PDGF, TGF-β play an important role in union, and PRP is used for the reparation of Cranial defect by some researchers, it is found that PRP is favourable
In stimulation skeletonization, accelerate Bone Defect Repari.PRP can be additionally used in decrease of platelet and hemorrhagic disease caused by treatment a variety of causes, and
Accelerating wound healing.
Existing equipment is when carrying out platelet rich plasma extraction, and cumbersome, accuracy is low, it is impossible to real easily and fast
The separation and Extraction of existing platelet rich plasma.
The embodiment of the present application provides a kind of floated platelet rich plasma separating extraction device of buoy, as illustrated, bag
Include top cover 100, body 200, bloodletting tube 300, the first buoy 400, the second buoy 500, buoy conduit 600.
The top cover 100 and the opening at the top of body 200 match, and the first end pipe is provided with the top cover 100
101, one end that first end pipe 101 is located inside the body 200 is connected with one end of the bloodletting tube 300, top cover
100 are used to close body 200, and one end of the first end pipe 101 is arranged on inside body 200, and the other end is arranged on outside body 200
Side, the one end for being located at the outside of body 200 by the first end pipe 101 can be to use other equipment by the blood inside body 200
Extracted by bloodletting tube 300.
The bottom outside of body 200 is plane, and the bottom inside of body 200 is conical socket, the outside of body 200
Plane causes body 200 more steady in placement, is not susceptible to topple over.The bottom inside of body 200 is arranged to conical socket and caused
Body 200 is when being centrifuged, and more preferably, the layering of blood is more thorough for centrifugal effect.
First buoy 400 is close to the bottom of body 200, and second buoy 500 is away from the bottom of body 200
Portion, the buoy 500 of first buoy 400 and second is mobilizable to be arranged on the inner side of body 200, first buoy 400
Conical socket shape close to the shape and the bottom inside of body 200 of one end of the body 200 matches, and described second
Buoy 500 matches close to one end of the bottom of body 200 and the shape of the other end of first buoy 400.
In the embodiment of the present application, it is provided with two buoys inside body 200, and preferred, first buoy
The density and density that 400 density is more than platelet rich plasma are less than blood plasma containing red blood cell, and the density of second buoy 500 is small
Density in platelet rich plasma and the density more than platelet poor plasma.
In addition, being provided with space between the buoy 500 of the first buoy 400 and second and the inside of the body 200.First
The diameter of the buoy 500 of buoy 400 and second can be set smaller than the internal diameter of body 200, make the first buoy 400 and the second buoy
Contact not close between 500 and the inwall of body 200, or the first buoy 400 and the second buoy 500 with the inwall of body 200
Between be in contact, but multiple grooves are set on the edge of the first buoy 400 and the second buoy 500, blood can be by these
Groove enters different delamination areas, and specific facilities can be according to actual set.
By setting the different buoy of two density, and space is left between buoy and body 200 so that body 200 is deposited
Storage blood centrifuged after, can be separated into three layers by two buoys, blood can be divided into three layers after being centrifuged, from top to bottom according to
Secondary is platelet poor plasma, platelet rich plasma and blood plasma containing red blood cell.Because the density of the first buoy 400 is more than rich platelet
The density of blood plasma, and density is less than blood plasma containing red blood cell so that the first buoy 400 can be in platelet rich plasma and containing red blood cell
Between blood plasma, platelet rich plasma and blood plasma containing red blood cell are separated.And the density of second buoy 500 is less than rich blood
The density of platelet-poor plasma and the density for being more than platelet poor plasma, the second buoy 500 is located in platelet rich plasma and anaemia is small
Between plate blood plasma, platelet rich plasma and platelet poor plasma are separated, platelet rich plasma is located between two buoys.
In addition, one end of the buoy conduit 600 and the one end of first buoy 400 away from the bottom of body 200
It is mutually fixed, the through hole 501 for accommodating the buoy conduit 600 is provided with second buoy 500, the buoy conduit 600
The other end is connected through the through hole 501 on second buoy 500 with the other end of the bloodletting tube 300, and the buoy is led
Multiple platelet rich plasma through holes 601 are provided with the side wall of pipe 600.
Buoy conduit 600 in the embodiment of the present application after the completed centrifugation, due to buoy conduit 600 one end with first float

Work, it is possible to body 200 is put into centrifuge, passes through the rotating centrifugal of centrifuge so that the blood inside body 200
By centrifugation layering.Blood is in centrifugal process, and blood can enter different layerings by the gap between buoy and body 200
Region.Blood after centrifugation layering can be separated into three layers by two buoys, and the platelet rich plasma that treatment needs is located in two
Between buoy.Rich platelet blood is offered due to being additionally provided between two buoys on buoy conduit 600, buoy conduit 600
Starch through hole 601.One end that the outside of body 200 can be now located in the first end pipe 101 connects a syringe, is injected by twitching
The push rod of device, negative pressure is internally formed in syringe, now under the driving of negative pressure, and platelet rich plasma just passes through buoy conduit
Platelet rich plasma through hole 601 on 600 is entered in buoy conduit 600, passes through the first end pipe 101 and buoy conduit 600
Between bloodletting tube 300, finally from the first end pipe 101 flow out body 200.By constantly extracting, it is possible to by two buoys
Between platelet rich plasma be all drawn into the outside of body 200, complete the extraction work of platelet rich plasma.
The body can be made up of medical plastic.Or use other materials.
In the embodiment of the present application, the inside of body 200 is provided with the different buoy of two density, is carrying out the centrifugation of blood
Afterwards, blood plasma is layered and is separated into three layers by two buoys, and platelet rich plasma is located between two buoys, passes through buoy conduit
600 and bloodletting tube 300 platelet rich plasma can be just drawn into outside body 200, realize extraction to platelet rich plasma.
The device provided using the application, the collection that foolproof can be realized to platelet rich plasma is extracted, simple to operate,
Only need to collection of the once-through operation with regard to platelet rich plasma can be completed to extract, it is not necessary to aspirate repeatedly, extraction effect is more preferable, and can
Sufficiently extract, be difficult to remain and other plasma fractions will not be drawn into, the utilization ratio to blood is higher, and usage experience is more
