Description
Technical field
This utility model relates to medical instruments field, is specifically related to a kind of PRP extraction element.
Background technology
Platelet rich plasma (PRP) under household condition can be prepared in operating room, but must keep aseptic in centrifugal process, and need to separate under not having the high concentration of thrombocytolysis or destruction, and PRP result prepared by different PRP extraction elements is different.
CN202426528U authorizes a kind of PRP rapid extraction evacuated blood collection tube, utilizes the proportion of blood separating colloid more than platelet and blood plasma but less than the principle of blood cell, separation and Extraction PRP.But the PRP that this collection tube extracts is mixed with impurity, and concentration is low, simultaneously easily caused by pollution.
CN202860184U authorizes a kind of blood PRP separator, and this separator is hourglass shape, utilizes adjustment handle to be lifted up by plasma layer, then extracts PRP extract with sealing withdrawal device.The existence of withdrawal device makes this separator be difficult to operate in centrifugal process, and withdrawal device easily extracts impurity, and extraction effect is poor.
CN103566629A discloses a kind of blood rich platelet separating and extracting process and device, this device includes PRP locker room, blood plasma locker room, PRP/ erythrocyte securing rod swing handle and erythrocyte locker room, utilize the height moving up and down regulating liquid surface of PRP and erythrocyte locker room, close with PRP/ erythrocyte securing rod and cut off different cellular layers, thus completing the whole process of separation and Extraction.Although this invention overcomes the defect of easily pollution, but in centrifugal process, blood plasma can stick on securing rod, inferior separating effect.
Summary of the invention
The purpose of this utility model be in that provide a kind of easy operation, good separating effect and be not readily susceptible to outside contamination PRP extraction element.
A kind of PRP extraction element, includes impurity storage part, PRP storage part, separatory portion and erythrocyte storage part from top to bottom successively.
Described separatory portion is by adjusting knob, separatory hole, rubber ring and fixed knob composition.
Described separatory hole is positioned at the central authorities in separatory portion, and pore size is identical with the lower end caliber size of PRP extraction unit.
The end in described separatory portion is provided with rotation screw thread, matches with the screw thread within fixed knob, in order to fixing separatory portion.
The diameter of described rubber ring is identical with the diameter of fixed knob, slightly larger than the diameter of the separatory portion body of rod.
The top of described extraction element is provided with blood hand-hole, and described blood hand-hole surface is provided with lid.
The central authorities of described lid are provided with a passage, and passage is provided with ventilative resistance Mycoderma, and ventilative resistance Mycoderma covers protection foil film.
There is containing mark on the surface of described impurity storage part and PRP storage part.
The side of described PRP storage part lower end is provided with PRP and extracts mouth.
The beneficial effects of the utility model: this utility model is integrated device, can complete whole separation process, have good separating effect, need not use miscellaneous part during separation, simple to operation, not easily causes pollution.

Detailed description of the invention
In conjunction with Fig. 1 to Fig. 3, this utility model includes impurity storage part 1, PRP storage part 2, separatory portion 3 and erythrocyte storage part 3 from top to bottom successively.
Described separatory portion 3 is made up of adjusting knob 5, separatory hole 6, rubber ring 7 and fixed knob 9.
Described separatory hole 6 is positioned at the central authorities in separatory portion 3, and pore size is identical with the lower end caliber size of PRP extraction unit 2.
The end in described separatory portion 3 is provided with rotation screw thread 8, matches with the screw thread within fixed knob 9, in order to fixing separatory portion 3.
The diameter of described rubber ring 7 is identical with the diameter of fixed knob 9, slightly larger than the diameter of separatory portion 3 body of rod, in order to seal fixed knob 9 and extraction element.
The top of described extraction element is provided with blood hand-hole 11, and described blood hand-hole 11 surface is provided with lid 10.
The central authorities of described lid 10 are provided with a passage 13, and passage 13 is provided with ventilative resistance Mycoderma, and ventilative resistance Mycoderma covers protection foil film.
There is containing mark on the surface of described impurity storage part 1 and PRP storage part 2.
The side of described PRP storage part 2 lower end is provided with PRP and extracts mouth 12, and described PRP extracts mouth 12 surface and is provided with lid.
Specifically used step of the present utility model is as follows:
1, first determine that the separatory hole 6 in separatory portion 3 does not communicate with PRP storage part 2 and erythrocyte storage part 4, then tighten fixed knob 9, make separatory portion 3 and overall extraction element fixing seal；
2, opening lid 10, the ACD-A anticoagulant extracting 2cc is injected in extraction element by blood hand-hole 11, extract simultaneously 20cc blood be injected in extraction element, cover lid 10；
3, the gross weight of this extraction element is weighed, prepare an identical extraction element, injecting a certain amount of water makes both weight identical, symmetrical for two extraction elements is put in centrifuge, with the centrifugal force 10min of 200g, after first time is centrifugal, blood is divided into three layers, orlop is the red blood cell layer that sedimentation coefficient is maximum, and the superiors are supernatant layer, and both intersections are platelet rich plasma layer；
4, it is slowly withdrawn extraction element; tear the protection foil film covered on the ventilative resistance Mycoderma of passage 13; fixed knob 9 is somewhat unscrewed; then adjusting knob 5 is slowly rotated; make separatory hole 6 slowly communicate with the lower end of PRP storage part 2, make red blood cell layer flow slowly into erythrocyte storage part 4 place, for ensureing that free from admixture is referred and synthesized; the platelet rich plasma layer of 1mm liquid level is also transferred in erythrocyte storage part 4 simultaneously, then separatory hole 6 is adjusted to closing partition；
5, after step 4 terminates, this extraction element is placed again into centrifuge, 200g centrifugal force 8min, after second time is centrifugal, impurity storage part 1 and in PRP storage part 2 blood be divided into two-layer, upper strata is impurity layer, and lower floor is high concentration platelet rich plasma layer；
6, the lid outside PRP drawing holes 12 is opened, with syringe from PRP drawing holes 12 pumping high-concentration platelet rich plasma layer.
