Abstract: A device and a method for adjustable quantitative injection of high-pressure gas are provided, wherein the gas may have a pressure of 5 MPa or more than 5 MPa. The gas may be directly communicated with a gas tank in the mechanism or an external gas source, flows through corresponding valves, and is charged into a predetermined or adjustable reservoir. Alternatively, the valve may be time-controllable, and does not need the reservoir. The gas is ejected through a nozzle selected based on depth or range of injection, wherein a one-way valve is disposed between the nozzle and the body to prevent contamination due to backflow. The manipulator can exert an appropriate force onto a target portion of a human for gas injection, and when the injection is done, a biasing member can automatically return the mechanism to its original state, ready for the next injection.

Abstract: A trigger point and acupoint stimulator (1) for connecting to a fluid ejection device (900). The trigger point and acupoint stimulator (1) comprises: a base (10) and a least one contact member (201). The base (10) has a transmission channel (CL1, CL1?). The contact member (201) is movably provided on the base (10) and has an ejection channel (CL2, CL2?). A tail end of the contact member (201) directly contacts a skin surface, and the contact member (201) can switch between a closed position and a communicated position to eject a fluid provided by the fluid ejection device (900) and to cause the pressurized fluid to directly act on the skin surface.
