Spraying rod-shaped an injection appliance and injection appliances construction kit

摘要

This syringe-like injection device for injection of a preselectable dose of a liquid medicament by means of a single stroke movement in the longitudinal direction of the device comprises two couplable, sleeve-shaped standard components (1, 2), a rack (5) which can be unidirectionally operated via a metering knob (3) and an engageable drive element (4) and which can actuate the stopper (7) of an ampoule (8) with its free end (6), and a cannula (9). The injection device in modular design essentially comprises a lower standard component (2) surrounding the ampoule section (8) with cannula (9), and a series of upper standard components (1) which contain the dispensing mechanics with metering knob (3), engageable drive element (4) and rack (5), and which can be assembled so that in each case a lower standard component (2) can be selectively combined with an upper standard component (1). Furthermore, it comprises a lockable dispensing mechanism. IMAGE
