Embodiment Construction

[0038] see figure 2 and image 3 As shown, it is a three-dimensional schematic diagram and an exploded schematic diagram of a preferred embodiment of the present invention. It can be clearly seen from the figure that the present invention is a platelet-rich plasma collection device 2, comprising: a tube body 20, the two ends of the tube body 20 An opening 202 is defined respectively, and a narrow tube portion 22 with an inner diameter smaller than the inner diameter of the tubular body 20 is formed at the middle section of the tubular body 20; a cover body 24 for covering one of the openings 202 and one for closing the other Piston 3 with opening 202 .

[0039] The two ends of the narrow tube portion 22 respectively form a slope 220 connected with the tube body 20 and having a predetermined angle, and the predetermined angle is 100-150 degrees.

[0040] The inner diameter of the aforementioned tube body 20 is 1-1.6 cm, while the inner diameter of the narrow tube part 22 is ...

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 [0001] The present invention provides a centrifuge tube body structure, which is convenient to adjust the plasma layer, buffy coat, and red blood cells to a specific position after blood centrifugation, so as to collect plasma, red blood cells, or high-concentration platelet plasma, and also A platelet-rich plasma collection device that can be used to determine whether the red blood cell content is low or high. Background technique [0002] Press, the blood is centrifuged after adding anticoagulant, such as figure 1 , is a schematic diagram of layers of blood after centrifugation, which can generally be divided into three layers: a plasma layer 10 , a buffy coat 12 , and a red blood cell layer 14 . The buffy coat 12 is about 1% of the total volume, and it is not easy to distinguish and obtain from the plasma layer 10 and red blood cells 14 . [0003] Generally, the inner diameters of blood centrifuge tubes or blood collection tubes are designed to be the sa...
