[0022] In an embodiment of the present invention, in order to achieve spraying, a multi-way valve 8 is provided at the end of the liquid outlet head 7. The multi-way valve 8 is a three-way structure, two of which are connected to the liquid outlet head 7. The end of the spray pipe 901 is connected to the liquid outlet end of the multi-way valve 8 through a joint. The liquid outlet end of the multi-way valve 8 is provided with a mixing structure 9. The mixing structure 9 includes a spray pipe 901 and a spray head 902. The end of the spray pipe 901 is sleeved and fixed to the spray head 902. A control knob is provided on one side of the multi-way valve 8. The control knob can control the single connection, double connection, etc. inside the valve. By switching the single connection and pulling the two push rods, the liquid can be sucked, and then the spray head 902 can be switched to achieve atomized spraying.

[0023] In the second embodiment, although the above-mentioned specific ratio is achieved, the lack of mixing process during spray discharge may result in the separate discharge of platelet-rich plasma and thrombin in different regions and stages, resulting in poor medical effects. In view of this point, different from the above-mentioned, the mixing structure 9 also includes a mixing shell 903, the mixing shell 903 is fixed to the periphery of the multi-way valve 8, two guide tubes 904 are arranged inside the mixing shell 903, one end of the mixing shell 903 is connected to the spray pipe 901 through a joint, wherein the multi-way valve 8 is a four-way structure, two of which are connected to the liquid outlet head 7, and the multi-way valve 8 is a four-way structure.
