Variable-length needle covering device of an injection device
First Claim
1. A needle covering device for an injection device, said injection device including a casing having a reservoir for a fluid product and an injection needle, wherein said covering device comprises:
- a rear section;
a front section linearly and axially moveable relative to the re-section so as to define an extended position that substantially surrounds the injection needle and a retracted position that exposes the injection needle, wherein a portion of the front section may be abutted against a surface to be injected.

Abstract
The invention relates to a needle covering device of an injection device, the injection device including a casing comprising a reservoir, in particular an ampoule, for a product fluid to be administered, and an injection needle for injecting the product fluid from the reservoir, wherein the device surrounds the injection needle in an extended position and exposes the injection needle in a retracted position. The device comprises a passage for the injection needle, a front section via which the device is placed on an injection point, and another section which is nearer to the casing than the front section is, at least in the extended position. The sections can be moved axially relative to the casing and relative to each other, such that the device is variable in its length, the front section being guided in a straight line on the casing.

29. An injection device comprising:
-
a housing;
a reservoir in the housing;
an injection needle coupleable with the housing and the reservoir, wherein when coupled with the housing the needle defines an axis extending outward from the housing;
a cylindrical rear sleeve coupled with the housing and disposed concentrically about the axis;
an cylindrical intermediate sleeve moveably coupled to the rear sleeve and disposed concentrically about the axis, wherein the intermediate sleeve is moveable to a position substantially within the rear sleeve; and
a cylindrical front sleeve moveably coupled to the intermediate sleeve and disposed concentrically about the axis, wherein the front sleeve is moveable to a position substantially within the intermediate sleeve, wherein the rear sleeve, the intermediate sleeve and the front sleeve are linearly moveable with respect to one another to selectively cover and expose the needle. - View Dependent Claims (30, 31, 32)
