A gas-powered, single-use, needle-less hypodermic jet injection device (10, 210, 410) includes a hand-held injector (12, 212, 412), and a drug injection cartridge (14, 114, 414) which provides a volume of liquid medication to be injected, an injection orifice, and an injection piston. Forceful movement of the injection piston causes an injection jet of medication to be expelled from the injection orifice. The injection device also includes a hermetically sealed gas pressure cartridge (82, 182, 482) which remains sealed until the moment of injection and powers the jet injection after opening of this cartridge.

The wearable muscular-force supplementing device according to claim 1, further comprising: said artificial muscular-force generator being electrically driven; a power switching mechanism; and power sources including a main power source and an auxiliary power source, said main power source and said auxiliary power source being connected to the power switching device, said power switching device performing switching so as to supply power from said auxiliary power source for a predetermined time when power supply from said main power source is stopped. 5. The wearable muscular-force supplementing device according to claim 4, wherein said power switching device has an alarm device that sounds an alarm when power supply from said auxiliary power source is started. 6. A wearable muscular-force supplementing device according to claim 1, further comprising: said artificial muscular-force generator having a pair of mounting portions to be worn at two positions on the body of the user on both sides of the joint, and an actuator connected between said mounting portions, said actuator having a restraint that prevents excessive supplementary muscular force from being applied to the joint of the user. 7. The wearable muscular-force supplementing device according to claim 6, wherein said restraint is formed by placing stopper members opposed to each other in said mounting portions so that the positions thereof are adjustable and so that said stopper members contact before excessive supplementary muscular force is applied to the joint of the user. 8. The wearable muscular-force supplementing device according to claim 6, wherein said restraint is formed by connecting a variable-length elastic belt between said mounting portions so that the force of said actuator is stopped by tension generated by said elastic belt before excessive supplementary muscular force is applied to the joint of the user. 9. A wearable muscular-force supplementing device according to claim 1, further comprising: said artificial muscular-force generator having a fluid-pressure type actuator having a pressure chamber; and said controller including a fluid transfer control section that controls transfer of the fluid with respect to said actuator, at least one of said actuator and said fluid transfer control section having a fluid discharge control section that discharges internal fluid to the exterior of the device. 10. The wearable muscular-force supplementing device according to claim 9, wherein said fluid discharge control section has a leakage alarm that detects leakage of the fluid and sounds an alarm when discharge of the fluid out of at least said actuator and said fluid transfer control section is stopped. 11. The wearable muscular-force supplementing device according to claim 9, wherein said controller includes a fluid supply control section capabl
