Abstract
The utility model relates to a centrifugal pipe and a pipette for preparing plasm which is rich of platelets. The centrifugal pipe is mainly composed of a pipe body, a pipe cover and the pipette, and is characterized in that a multifunctional hole is arranged on the pipe cover, a hole cover is arranged on the hole, the outside diameter of the pipette is smaller than the inside diameter of the multifunctional hole, and the pipette is longer than the pipe body and is used by matching with an injector. In an implementing process, the plasm which is rich of the platelets is prepared by centrifugation twice; after blood is taken out, the blood is placed in the centrifugal pipe; after the first centrifugation, the blood in the pipe body is divided into three layers; after the pipette is matched with the injector to extract proper quantities of red blood cells through the multifunctional hole, the residual blood in the centrifugal pipe is evenly shaken; then, the second centrifugation is carried out, and the injector is used for extracting proper amounts of supernatant liquid; then, the residual blood in the centrifugal pipe is evenly shaken again and is prepared 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 greatly reduced, and the preparing speed and the result precision are increased.
Description
Technical field
This utility model relates to a kind of medical apparatus, specifically a kind of centrifuge tube and pipette.
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, centrifuge tube easy to use and pipette.
The technical scheme that its above-mentioned technical problem that solves this utility model adopts is: a kind of centrifuge tube and pipette that is used to make platelet rich plasma, it mainly comprises body, pipe lid and pipette.It is characterized in that: pipe covers and is provided with multi-functional hole, and the hole is provided with the hole medicated cap, and the external diameter of pipette is littler than multi-functional hole internal diameter, and length is longer than body, can cooperate syringe to use.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, cooperate syringe by multi-functional hole with pipette, 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 is drawn an amount of supernatant in multi-functional hole, 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.
Fig. 1 is the structural representation of this utility model centrifuge tube.
Fig. 2 is the structural representation of this utility model pipette.
Among the figure: the 1.. body, 2. pipe covers, 3. multi-functional hole, 4. hole medicated cap, 5. pipette.
The specific embodiment
In the drawings, pipe covers 2 and is provided with multi-functional hole 3, and multi-functional hole 3 is provided with hole medicated cap 4, and the external diameter of pipette 5 is littler than multi-functional hole 3 internal diameters, and length is longer than body 1, can cooperate syringe to use.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, after cooperating syringes to extract an amount of erythrocyte by multi-functional hole 3 with pipette 5, remaining blood in the centrifuge tube is shaken up, it is centrifugal to carry out the second time then, the reuse syringe is in multi-functional hole 3, draw 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, avoid moving the liquid process, significantly reduced 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.
