Specific embodiment
Below in conjunction with the attached drawing in the utility model, the technical solution in the utility model is carried out clearly and completely
Description.
Fig. 1-5 is please referred to, the one of embodiment of the utility model provides a kind of injector type PRP extraction assembly, including
The detachable screw syringe of bar core, plugging cap 1, beveled injection needle 2 and scalp acupuncture 3.
The detachable screw syringe of bar core includes outer cylinder 4, can slide in 4 inner cavity of outer cylinder and detachable with outer cylinder 4
The bar core 5 of connection, can be by the piston 6 of 4 bore seal of outer cylinder, one end of outer cylinder 4 is equipped with screw socket, as shown in fig. 6, the screw socket packet
Include the screw socket set 42 with the port 41 of inner cavity connection and set on 41 periphery of port.The plugging cap 1 is used for the port 41 of screw socket
Sealing.
As shown in figure 3, the piston 6 includes the piston base 8 of piston seal 7 and nut structure, piston seal 7 is adopted
It is made of rubber material, piston base 8 is made of polypropylene material, and the bottom surface of the piston base 8 is (towards the one of port 41
End) slightly it is arc-shaped, as shown in Figure 3.
Piston seal 7 can be socketed on piston base 8；As shown in figure 4, the plugging cap 1 includes having hollow cavity
Body part 10, the pellosil 9 that seals the lower port of hollow cavity positioned at 10 bottom of body part and be set to 10 liang of body part
The lug 11 of side, body part 10 can be socketed with the port 41 of 4 bottom end of outer cylinder, make the interior of the hollow cavity of body part 10 and outer cylinder 4
Chamber connection.The lug 11 is used to be cooperatively connected with screw socket set 42, and then realizes that the connection of plugging cap 1 and screw socket seals.It is described
Lug 11 is designed as external thread structure, and the inner wall of the screw socket set 42 is equipped with internal screw thread, the external thread structure and screw socket of lug 11
