NEEDLE-FREE INJECTION DEVICE, E.G. FOR INJECTING INSULIN

摘要

In an inoculating apparatus between the inoculating unit and the actuating unit a quick coupling mechanism is inserted. The inoculating device itself becomes actuated by means of a siphon-cartridge via a valve performing a triple function. The structure ensures the discharge of the carbonic acid gas quantity required for operation through the bore of the piston, simultaneously it prevents further outflow of the carbonic acid gas from the cartridge after work performance.
