Abstract
Drug delivery devices are described that provide hybrid forms with optional gripping functionalities. For example, the devices can include a grip portion on a skin contact surface with a release liner disposed thereon. A user can operate the devices with the release liner disposed on the grip portion or can remove the release liner so that the grip portion is able to aid users in orienting and supporting the device during an injection operation.

A drug delivery device comprising:
- a housing having a bottom wall with a generally planar skin contact surface and an opening extending therethrough;
- drug delivery components disposed within the housing including a needle having a storage position within the housing and an injection position extending through the opening of the bottom wall;
- a tacky portion of the bottom wall configured to grip skin of a user;
- and
- a release liner disposed over at least a portion of the tacky portion;
- wherein the drug delivery components have a first potential operation state with the release liner disposed over at least the portion of the tacky portion and a second potential operation state with the release liner removed to expose the tacky portion.
A method of preparing a drug delivery device prior to injecting a patient with a drug, the method comprising:
- providing a housing having a bottom wall with a generally planar skin contact surface and an opening extending therethrough, the bottom wall having a tacky portion;
- disposing drug delivery components including a needle within the housing;
- disposing a release liner over at least a portion of the tacky portion;
- and
- either (a) or (b):
- (a) moving the needle from a storage position within the housing to an injection position extending through the opening of the bottom wall in a first operation state wherein the release liner remains disposed over at least a portion of the tacky portion,
- (b) removing the release liner to expose the tacky portion and define a second operation state, and moving the needle from a storage position within the housing to an injection position extending through the opening of the bottom wall.
