Description
Technical field
This utility model belongs to technical field of medical instruments, is specially a kind of special equipment of rapid extraction rich platelet high concentration blood plasma.
Background technology
(Platelet Rich Plasma PRP), is the platelet blood plasma that contains high concentration that obtains by centrifugal blood to rich platelet high concentration blood plasma.The platelet of human body can produce protein (fibrin, fibronectin ﹠amp with cell adhesion function under the high concentration state; Vitronectin), Chinese: fibronectin, fine mucin, and when pH value drops to 6.5-6.7 from 7.0-7.2, add suitable calcium chloride, can promote a large amount of secretions of platelet that 9 kinds of somatomedin that promote wound, organization healing and cell regeneration are arranged, so PRP also is called " being rich in somatomedin blood plasma ".PRP has the effect of rapid hemostasis, pain relieving, accelerating wound healing, and greatly degree alleviates the formation of scar after the operation.In addition, because PRP extracts, through extracting after enrichment handles, can be used for the treatment of relevant disease, thereby the source is abundant from patient's self-blood, draws materials conveniently, preparation method is simple and can allow health absorb.Self PRP uses the problem that can avoid virus disseminating and immunologic rejection to occur.Therefore since middle nineteen nineties in last century, be widely used in various surgical operations, operation on heart and plastic operation, also be widely used in the medical cosmetology aspect at present.So the extraction quality of PRP is the key factor that influences its function and effect.
At present, the PRP preparation method is obviously simplified, and under household condition namely can prepare in operating room, but must keep aseptic in centrifugal process, and separate under the high concentration that does not have thrombocytolysis or destruction, and the PRP of different PRP instrument preparations is difference as a result.Some PRP instrument can not produce the platelet that concentrates sufficient amount, that promote healing, and this can explain many about using the invalid research of PRP.Real PRP should because the allosome platelet does not have vigor, and can not secrete the biological activity somatomedin from body, and its cell membrane also is antigen, can stimulate body to produce antibody.The PRP preparation method roughly is divided into two classes.One class utilizes simple instrument such as centrifuge to prepare under common blood bank condition by manual operations, be easy to carry out, but operating procedure is comparatively loaded down with trivial details.Another kind method is separated preparation PRP automatically for using special blood separation instrument, this method is simply rapid, can in time feed back in patient's body separating the remaining blood constituent in back, but this activates platelet easily, the quality of PRP is descended, finally cause therapeutic effect not good.
