Abstract
The invention provides a injection device for administering an injectable product, including a base section adapted to receive a container from which a product dose is dispensed through a needle by displacement of a piston in the container, and a drive unit including a driven member, a drive element and a damping arrangement, the drive unit for applying a force to advance the piston in the container to dispense a dose, wherein the damping arrangement generally counteracts the drive force and counter forces. The invention also encompasses a needle safety sleeve and a blocking structure for use with injection devices.

11. A device for administering an injectable product, comprising:
-
a base section;
a drive unit, comprising at least a driven member and a drive element, the drive element applying a drive force on said driven member, whereby the driven member is displaced toward the base section; and
a damping arrangement operably coupled to the drive unit for generating a damping force. - View Dependent Claims (12)

13. A device for administering an injectable product, comprising:
-
a base section;
a drive unit, comprising at least a driven member and a drive element, the drive element applying a drive force on said driven member, whereby the driven member is displaced toward the base section; and
a needle safety sleeve displaceably coupled to said base section and having a base position in which it generally surrounds a needle operably coupled to the device and an administering position, in which the needle projects beyond said needle safety sleeve, said needle safety sleeve being releaseably blockable against displacement.

14. A device for administering an injectable product, comprising:
-
a) a base section;
b) a container arranged in the base section from which container a product dose is dispensed through a needle by displacement of a piston associated with the container;
c) a drive unit, comprising a driven member and a drive element, the drive element applying a drive force on said driven member upon actuating the drive unit, by which drive force said driven member is displaced in the direction of the piston, thus advancing said piston within said container; and
d) a stripper carried on the device, said stripper movable back and forth in a longitudinal direction of the needle in order to strip off a needle safety cap applied to the needle, said stripper carried on the device in such a way as to allow said stripper to remain on the device during an injection and to be pushed back for insertion of said needle. - View Dependent Claims (5, 6, 8, 9, 10)
