ABSTRACT:
The suction injecting unit comprises a tubular housing adapted for receiving a disposable container for receiving the medicine to be administered, and having at one end a socket for exchangeably supporting a cannula and a removable suction cup, and at the other end a piston combined with a dosing mechanism that allows only a preset stroke of the piston. A suction apparatus controlled preferably by a pressurized gas is attached to the housing and is provided with control valves to successively establish an underpressure in the suction cup, and to maintain the underpressure in the cup while moving the piston about a predetermined stroke.
