Abstract

The utility model relates to a centrifugal pipe for preparing plasm which is rich of platelets. The centrifugal pipe is mainly composed of a pipe body and a pipe cover and is characterized in that the lower part of the pipe body is provided with a pipe hole, a pipe cover is arranged outside the pipe hole and is made of elastic materials, a supernatant liquid sucking hole and a balanced pressure hole are arranged on the pipe cover, hole covers are arranged on the holes, and a ventilating film is arranged in the balanced pressure hole and is used for balancing the pressure in the pipe body when red cells and supernatant liquid are sucked. In an implementing process, after blood is taken, the blood is put into the centrifugal pipe; after the first centrifugation, the blood in the pipe body is divided into three layers; after an injector is used for sucking proper quantities of red cells by puncturing the pipe cover arranged on the lower part of the pipe body, the residual blood in the centrifugal pipe is evenly shaken; then, the second centrifugation is carried out, and the injector is used for sucking proper amounts of supernatant liquid from the supernatant liquid sucking hole; then, the residual blood in the centrifugal pipe is evenly shaken again and is made into the plasm which is rich of the platelets. The whole preparing process can be completed in one centrifugal pipe, a liquid removing process is avoided, the pollution of a sample is reduced, and the preparing speed and the result precision are increased.

Description

Be used to make the centrifuge tube of platelet rich plasma
Technical field
This utility model relates to a kind of medical apparatus, specifically a kind of centrifuge tube that is used to make platelet rich plasma.
Background technology
At present, common centrifuge tube structure is single, has following shortcoming in the process of making platelet rich plasma: 1. blood is after the first time is centrifugal, being transferred to another centrifuge tube, to carry out the second time centrifugal, in this process, blood contacts the external world easily, causes sample contamination.2. move liquid with common suction pipe in the routine operation, move liquid often, speed is slow, and causes easily that precision is not good enough as a result.3. common centrifuge tube is owing to the restriction of volume and shape, and the platelet rich plasma of made only is enough in index and detects, and can't be used for the reparation of osseous tissue and soft tissue injury.The patent No. is 2004.20081020.8. a kind of patent that is used to make the centrifuge tube of platelet rich plasma by name, announced a kind of new centrifuge tube, but still there is weak point in this patented technology, for example: be provided with a red-count pipette and a supernatant suction pipe in the mouth of pipe body, the setting of these two pipes is exactly inappropriate, because blood takes out when being placed in this centrifuge tube, be used to extract out and also be full of blood in the erythrocytic suction pipe simultaneously, after for the first time centrifugal, manage intravital blood when being divided into three layers, blood in the red-count pipette also can form three layers simultaneously, so the erythrocyte that extracts in this red-count pipette is impure, and the suction pipe of the supernatant of its setting just not have necessity of existence at all, because grown the middle level that can be inserted into after the blood separation, lacked and to have taken out less than supernatant.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of simple structure is provided, and the centrifuge tube of platelet rich plasma is made in easy to use being used to.
The technical scheme that its above-mentioned technical problem that solves this utility model adopts is: a kind of centrifuge tube that is used to make platelet rich plasma, it mainly comprises body, Guan Gai.It is characterized in that: the body bottom is provided with a mouth of pipe, and the mouth of pipe is provided with pipe cap outward, and pipe cap is made with elastomeric material, pipe covers and is provided with supernatant suction hole and balance pressure port, the hole is provided with the hole medicated cap, and equalizing pressure is provided with ventilated membrane in the hole, balance body internal pressure when being used to aspirate erythrocyte and supernatant.In force, make platelet rich plasma and need secondary centrifuging, blood takes out and is placed in this centrifuge tube, after for the first time centrifugal, manage intravital blood and be divided into three layers, with the pipe cap of syringe by puncture body bottom, extract an amount of erythrocyte after, remaining blood in the centrifuge tube is shaken up, it is centrifugal to carry out the second time then, and the reuse syringe covers supernatant from pipe and inhales in the hole, draws an amount of supernatant, then remaining blood in the centrifuge tube is shaken up once more, promptly can be made into platelet rich plasma, entire making process just can be finished in a centrifuge tube, has avoided moving the liquid process, significantly reduce sample contamination, improved manufacturing speed and degree of accuracy as a result.This utility model can be made into the centrifuge tube of a plurality of specifications, can disposable a large amount of making platelet rich plasma with this centrifuge tube, can be widely used in the reparation behind osseous tissue and the soft tissue injury, and also can be used for scientific research and medical test section office blood constituent is purified.
The beneficial effects of the utility model are: simple in structure, easy to use, can disposable a large amount of making platelet rich plasmas, and can be widely used in the reparation behind osseous tissue and the soft tissue injury, also can be used for scientific research and medical test section office blood constituent is purified.
Description of drawings
Below in conjunction with accompanying drawing this utility model is further specified.
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1. pipe cap, the 2. mouth of pipe, 3. body, 4. pipe lid, 5. supernatant is inhaled hole, 6. equalizing pressure hole, 7. hole medicated cap.
The specific embodiment
In the drawings, body 3 bottoms are provided with a mouth of pipe 2, the mouth of pipe 2 outer pipe caps 1 that are provided with, pipe cap is made with elastomeric material, pipe covers 4 and is provided with supernatant suction hole 5 and balance pressure port 6, the hole is provided with hole medicated cap 7, is provided with ventilated membrane in the equalizing pressure hole 6, balance body 3 internal pressures when being used to aspirate erythrocyte and supernatant.In force, make platelet rich plasma and need secondary centrifuging, blood takes out and is placed in this centrifuge tube, after for the first time centrifugal, manage intravital blood and be divided into three layers, with the pipe cap 1 of syringe by puncture body 3 bottoms, extract an amount of erythrocyte after, remaining blood in the centrifuge tube is shaken up, it is centrifugal to carry out the second time then, and the reuse syringe cover on 4 in the supernatant suction hole 5 from pipe, draws an amount of supernatant, then remaining blood in the centrifuge tube is shaken up once more, promptly can be made into platelet rich plasma, entire making process just can be finished in a centrifuge tube, has avoided moving the liquid process, significantly reduce sample contamination, improved manufacturing speed and degree of accuracy as a result.This utility model can be made into the centrifuge tube of a plurality of specifications, can disposable a large amount of making platelet rich plasma with this centrifuge tube, can be widely used in the reparation behind osseous tissue and the soft tissue injury, and also can be used for scientific research and medical test section office blood constituent is purified.
