Siphon-cartridge activated automatic inoculating device wihtout needle for individual acculation, e.g. for insulinization

Claim 1

Siphon-cartridge actuated automatic inoculating device without needle for individual inoculation, comprising an inoculating cylinder and an actuating unit, a quick coupling means (32) releasably interconnecting the inoculating cylinder (1) and the actuating unit (2), said actuating unit comprising a working piston (5), carbonic acid gas contained in a cartridge support for actuation of said unit is allowed to flow to a rear-side of the working piston (5) by a valve (18) performing a triple function and after actuation, said valve enabling a discharge of said gas into the atmosphere through a bore (26) of the piston, wherein after completing the phase of inoculation, further outstream of carbonic acid gas from the cartridge is prevented by a sealing body (23), wherein a spring (24) of the valve (18) performing triple function permits the discharge of the remaining carbonic acid gas from the cartridge for preventing a pressure drop, further comprising a starter spring connected to a trigger pin and a hoisting arm, said starter spring being placed into a state of readiness by said hoisting arm (16).
