Abstract

An improved injection device has a casing containing an active substance reservoir, a cannula communicating with the reservoir, a device for inserting the cannula, and pump means for discharging the reservoir contents through the cannula. The cannula 11 is fixed relative to the casing and projects beyond the underside of the casing to the depth required for injection. The cannula is surrounded by a protective element which is moved by a spring drive from a first end position in which the protective device projects beyond the underside of the casing and beyond the cannula to a second end position in which the protective device does not project beyond the underside of the casing.
