Description

Technical Field

[0001] The utility model relates to a plasma preparation device, in particular to a platelet-rich plasma preparation device. Background Art

[0002] During the plasma preparation process, the original blood needs to be centrifuged to obtain the white blood cells and PRP layer;

[0003] In conventional preparation schemes, the puncture port protrudes from the outer wall of the second separation tube, resulting in the second separation tube occupying space as a whole. When the second separation tube is placed, the puncture port is easily in contact with the stent and contaminated.

[0004] In summary, how to avoid contamination of the puncture site has become an urgent problem that researchers in this field need to solve. Utility Model Content

[0005] The technical problem to be solved by the utility model is: how to avoid contamination of the puncture port;

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] The utility model is a platelet-rich plasma preparation device, comprising: a first separation tube; a second separation tube, which is connected to the first separation tube through a hose; a concave portion is inwardly concavely provided in the middle of the second separation tube; a puncture port, which is arranged at the concave portion and communicated with the inside of the second separation tube;

[0008] In this scheme, blood is injected into the first separation tube, and the first and second separation tubes are placed on a centrifuge. After centrifugation, the tubes are separated into two layers. The rubber plug at the bottom of the first separation tube moves to push the red blood cells to the entrance of the second separation tube and stop. After the secondary separation, the supernatant of the second centrifuge tube is extracted by inserting a syringe into the puncture port, leaving the PRP to be extracted by the rubber plug at the bottom of the second shunt tube;

[0009] The puncture port is located at a recessed position in the middle of the second separation tube, so that the end of the puncture port protrudes from the outer wall of the second separation tube by a smaller distance, so that even if the outer wall of the second separation tube is contaminated, the puncture port will not be contaminated.

[0010] In order to specifically illustrate the length of the puncture port, the utility model adopts the distance from the end of the puncture port away from the second separation tube to the center line of the second separation tube as a; the outer wall radius of the top or bottom of the second separation tube is b; wherein b>a.

[0011] In this solution, the end of the puncture port is located in the recessed portion, which can reduce the space occupied by the second separation tube as a whole and will not contaminate the puncture port.

[0012] In order to illustrate the specific structure of the recessed portion, the utility model adopts the recessed portion as an annular groove;

[0013] The cross section of the annular groove may be a V-shaped structure or a semicircular structure, which can facilitate the cooperation between the puncture port and the recessed portion.

[0014] The beneficial effects of the utility model are as follows: the utility model is a platelet-rich plasma preparation device, the puncture port is located in a recessed position in the middle of the second separation tube, so that the end of the puncture port protrudes from the outer wall of the second separation tube by a smaller distance, and even if the outer wall of the second separation tube is contaminated, the puncture port will not be contaminated. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0016] Figure 1 It is a structural schematic diagram of the utility model;

[0017] Figure 2 is a cross-sectional view of the second separation tube;

[0018] In the figure: 1-first separation tube, 2-second separation tube, 3-hose, 4-recessed portion, 5-puncture port. DETAILED DESCRIPTION

[0019] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0020] like Figure 1-2 As shown, the utility model is a platelet-rich plasma preparation device, comprising: a first separation tube 1; a second separation tube 2, which is connected to the first separation tube 1 through a hose 3; a concave portion 4 is concavely provided inwardly in the middle of the second separation tube 2; a puncture port 5, which is provided at the concave portion 4 and communicated with the inside of the second separation tube 2;

[0021] In this scheme, blood is injected into the first separation tube, and the first and second separation tubes are placed on a centrifuge. After centrifugation, the tubes are separated into two layers. The rubber plug at the bottom of the first separation tube moves to push the red blood cells to the entrance of the second separation tube and stop. After the secondary separation, the supernatant of the second centrifuge tube is extracted by inserting a syringe into the puncture port, leaving the PRP to be extracted by the rubber plug at the bottom of the second shunt tube;

[0022] The puncture port is located at a recessed position in the middle of the second separation tube, so that the end of the puncture port protrudes from the outer wall of the second separation tube by a smaller distance, so that even if the outer wall of the second separation tube is contaminated, the puncture port will not be contaminated.

[0023] like Figure 2As shown, in order to specifically illustrate the length of the puncture port setting, the utility model adopts a distance a from the end of the puncture port 5 away from the second separation tube 2 to the center line of the second separation tube 2; the outer wall radius of the top or bottom of the second separation tube 2 is b; wherein b>a.

[0024] In this solution, the end of the puncture port is located in the recessed portion, which can reduce the space occupied by the second separation tube as a whole and will not contaminate the puncture port.

[0025] like Figure 2 As shown, in order to illustrate the specific structure of the recessed portion, the utility model adopts the recessed portion 4 as an annular groove;

[0026] The cross section of the annular groove may be a V-shaped structure or a semicircular structure, which can facilitate the cooperation between the puncture port and the recessed portion.

[0027] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
