Abstract
The invention relates to a platelet-rich blood plasma acquiring device. The device is composed of a tube with two ends respectively having an opening, a cover used for covering one opening, and a piston used for sealing the other opening. A narrow tube portion positioned in the middle section of the tube and having an internal diameter lower than the internal diameter of the tube uses the matching of the tube and a push bar to conveniently push the piston to move a buffy coat rich in platelets and leucocytes to the middle of the tube by the push bar after blood centrifuge. The narrow tube portion in the middle section of the tube makes the buffy coat more obvious, so a blood plasma having a high concentration of the platelets can be conveniently taken by a user. The cover positioned at one end of the tube makes the user easily open and operate.
Description
Technical field
The present invention is for providing a kind of centrifuge tube body structure, conveniently behind centrifugal blood, adjust plasma layer, buffy coat (buffy coat), red blood cell to ad-hoc location, obtain blood plasma, red blood cell or high concentration blood platelet blood plasma in order to collection, also can be used to judge the whether on the low side or too high blood platelet sampled plasma device that is rich in of erythrocytic content.
Background technology
Press, blood goes centrifugal after adding anticoagulant, and such as Fig. 1, the layering schematic diagram for behind the general centrifugal blood generally can be divided into three layers: plasma layer 10, buffy coat (buffy coat) 12, layer of red blood cells 14.And buffy coat (buffy coat) 12 is about cumulative volume 1%, is not easy to tell and obtain from plasma layer 10 and red blood cell 14.
The internal diameter design of general centrifugal blood pipe or heparin tube is equal width until the bottom, without special shape design the blood layering can obviously be manifested, especially buffy coat (buffy coat) part, and without the layering of mechanism design capable of regulating blood to ad-hoc location, allow the user conveniently obtain desired centrifugal rear blood position.So in the collection of being rich in blood platelet blood plasma, present and none simple and practical harvester.
Summary of the invention
Main purpose of the present invention is with the structural design of special centrifuge tube shape design with collocation, makes the layering of blood after centrifugal more obvious, conveniently obtains required buffy coat (buffy coat) or plasma layer and layer of red blood cells.
For reaching above-mentioned purpose, the present invention is a kind of blood platelet sampled plasma device that is rich in, and comprising: a body, and an opening is defined respectively at these body two ends, and is positioned at this body middle section and forms an internal diameter less than the narrow pipe section of this internal diameter of tube body; And lid and piston that is used for another opening of sealing that is used for hiding this opening wherein.
Wherein this narrow pipe section forms respectively one and links with this body in two ends, and possesses the inclined-plane of a predetermined angular, and this predetermined angular is the 100-150 degree.
Aforesaid internal diameter of tube body is the 1-1.6 centimetre, and narrow pipe section internal diameter then is the 0.2-1 centimetre.
The position is used in body inside preventing that piston that liquid spills then can be subject to pushing of push rod and moves to the other end.
Because body is by polypropylene material made, its size is close with general centrifuge tube or heparin tube with caliber, but middle narrow pipe section then with funnel-form as design, in the middle of being to allow, main purpose narrows down, but and utilize push rod immediate roof push piston, behind centrifugal blood, be used for mobile buffy coat (buffy coat) to pipe central authorities, thus, buffy coat can be concentrated in narrow pipe section, the blood layering is also more obvious, and buffy coat (buffy coat) can be resolved out in the middle of plasma layer and layer of red blood cells easily, makes things convenient for the user to obtain and is rich in hematoblastic blood plasma.
Secondary objective of the present invention is: use the position at lid and the piston at body two ends, then allow the user open easily and operate and prevent liquid (blood) outflow bottom body.
Another object of the present invention is to: obtain blood plasma, red blood cell or high concentration blood platelet blood plasma in order to collection, can be used to also judge whether erythrocytic content is on the low side or too high.
Another purpose of the present invention is: previous device all need use the specific centrifuge of collocation, the high concentration blood platelet blood plasma (PRP) of obtaining consuming time with expending, harvester of the present invention is applicable to most centrifugal machine, and only need centrifugal one time 10 minutes, the special design structure (narrow pipe section) of collocation harvester, can focus on collection place to buffy coat (buffy coat) easily, gather in a large number the PRP of high-quality behind the purifying.

The specific embodiment
See also Fig. 2 and shown in Figure 3, schematic perspective view and decomposing schematic representation for preferred embodiment of the present invention, find out that by knowing among the figure the present invention is a kind of blood platelet sampled plasma device 2 that is rich in, comprise: a body 20, an opening 202 is defined respectively at these body 20 two ends, and is positioned at these body 20 middle sections and forms an internal diameter less than the narrow pipe section 22 of these body 20 internal diameters; Lid 24 and a piston 3 that is used for another opening 202 of sealing that is used for hiding this opening 202 wherein.
Wherein this narrow pipe section 22 forms respectively one and links with this body 20 in two ends, and possesses the inclined-plane 220 of a predetermined angular, and this predetermined angular is the 100-150 degree.
See also in addition Fig. 6, be positioned at body 20 inner belows one piston 3 then is set, go out to prevent liquid leakage by this piston 3.
Please cooperate simultaneously and consult Fig. 4, Fig. 5, Fig. 6, Fig. 7 and shown in Figure 8, for the present invention adds using view, the view after centrifugal, the view, the buffy coat that promote push rod to be positioned at the view of narrow pipe section and being the local enlarged diagram of Fig. 7 of blood, find out by knowing among the figure, consult Fig. 4, at first the lid 24 on the body 20 is opened, it is centrifuge tube that 6 to 10 milliliters blood is put into this body 20(), add about 0.5 to 2 milliliter anticoagulant, so that about 7 to 11 milliliters of cumulative volume covers lid 24 and carries out centrifugal operation.With the centrifugal blood layering, only need once centrifugal 1000～2000g, about 10 minutes.It then is the state of having finished after centrifugal in Fig. 5, can see buffy coat (buffy coat) 50 approximate number centimetre place below body 20 centres after centrifugal, in buffy coat (buffy coat) 50 tops are plasma layers 52, in buffy coat (buffy coat) 50 belows then is layer of red blood cells 54, then, consult Fig. 6 and Fig. 7, then be to utilize push rod 4 to prop up piston 3 and touch, at this moment, buffy coat 50 is moved to the narrow pipe section 22 of body 20 central authorities, buffy coat 50 can be concentrated to more smoothly narrow pipe section 22 owing to have the inclined-plane 220 of 100-150 degree in the process of squeezing heap, it is worth mentioning that most, body 20 internal diameters are that the narrow pipe of 1-1.6 centimetre section 22 internal diameters then are the 0.2-1 centimetre, therefore more can know the position of concentrating and picking out buffy coat 50, in addition, can in Fig. 8, obviously see the layering of blood and the position of buffy coat 50.
