Description
Technical field
The utility model is about a kind of closed blood platelet inspissator.
Background technology
Blood of human body is being undertaken the important process of the interior oxygen of body and Energy Transfer, it is one of indispensable biological element of life system normal operation, based on this, in the clinical treatment and check field of medical science, all develop various application technology centered by blood component, wish by correctly and promptly obtain and analyzing blood composition in contained cell or material, with in response to different physiology or pathology demand.
Blood is made up of this four large element of red blood cell, white blood cell, blood plasma and blood platelet, each element has specific effect, and for example red blood cell is taken oxygen, and white blood cell function is resisted infection, blood plasma contains nutriment, mineral matter, water and protein, and blood platelet has the important function of hemostasis; For a long time, blood platelet is considered to only have the function of blood coagulation, hemostasis in blood always, but the medical research of recent years, the function of metabolism, help tissue repair and healing in the adjustable human body of discovery blood platelet.
The dense blood plasma of blood platelet (Platelet Rich Plasma, PRP) be the sedimentation coefficient difference according to each composition in autoblood, by gradient centrifugation by dense blood platelet blood plasma (Platelet Rich Plasma, PRP) platelet concentrate of separating from blood, but there is no at present unified preparation method; Because of the prepared dense blood plasma of blood platelet (the Platelet Rich Plasma of the different Starting mode of the centrifugal number of times of difference, centrifugal force, centrifugation time and blood platelet, PRP) in, its platelet counts, various growth factor concentration, leukocytic quantity are different, and the dense blood plasma of various modus operandi application blood platelet (Platelet Rich Plasma, PRP) time also produces different biological effects, therefore produced the difference to the dense blood plasma of blood platelet (Platelet Rich Plasma, PRP) biological effect; Along with the development of medical technology, at present existing multiple technologies can produce the dense blood plasma of safe blood platelet (Platelet Rich Plasma fast, PRP), and there is very large application space in clinical research, check, operation, medical cosmetology, bone surgery, hair regeneration, athletic injury treatment, the field such as healing of accelerating burn and scald mouth, if further investigated attentively, believes and is bound to bring greatest contribution to human health.
With regard at present known blood component isolation technics, mainly general with gradient centrifugation technology, it in its operation, is the characteristic of utilizing the sedimentation coefficient difference of blood component, blood is separated into three layers of different components such as plasma layer, the dense blood plasma of blood platelet (Platelet Rich Plasma, PRP), blood cell.
But, the dense blood plasma of blood platelet (Platelet Rich Plasma, PRP) preparation method there is no unified standard at present, still indefinite factor such as large, the contained growth factor quantity of the dense blood plasma of blood platelet (Platelet Rich Plasma, PRP) growth factor concentration difference, the interaction mechanism of growth factor that distinct methods is prepared; Therefore to the dense blood plasma of blood platelet (Platelet Rich Plasma, PRP) first research will set up a set of efficient stable, the dense blood plasma of blood platelet (Platelet Rich Plasma, the PRP) preparation method that little to platelet destruction, purity is high and stable.
See the dense blood plasma of current blood platelet (Platelet Rich Plasma, PRP) preparation method can be divided into manual preparation and two kinds of full-automatic preparations substantially, manual preparation process is more loaded down with trivial details, but equipment needed thereby is simple, easy operating, but the dense blood plasma of blood platelet (Platelet Rich Plasma, PRP) purity and concentration are not high, and because operator's fluency itself easily affects its stability, full-automatic blood platelet separates preparation needs special installation, though easy and simple to handle, automaticity is high, the dense blood plasma of blood platelet (the Platelet Rich Plasma preparing, PRP) purity and concentration are all high, but the method is generally used for blood using amount more (more than 150ml) and maybe needs to set up venous circulation passage person, be mainly used at present the hematoblastic collection of blood bank to carry out composition blood transfusion, because of its cost higher, limit it in clinical extensive use, from being necessary to manage to solve improvement.
The inventor is engaged in many years of experience and the technology of relevant medical material industry in line with it, spy sets about researching and developing closed blood platelet inspissator of the present utility model, to solve the separation of current blood component and the technical difficulty obtaining, guarantee the autoblood efficient stable separating and the purity and the concentration that separate rear each composition.
