Abstract
A disposable, wearable, self-contained insulin dispensing device includes a housing and an insulin source in the housing that is connected to a catheter for injecting insulin into a user. The catheter projects generally perpendicularly to a generally planar surface of the housing configured for abutting a skin surface of the user; which planar surface includes an adhesive layer for adhering the housing surface to the skin surface. A removable release sheet covers the adhesive layer for protecting the adhesive layer prior to use of the device. The release sheet is provided with a catheter protection element to enclose and protect an end portion of the catheter, such that removal of the release sheet for exposing the adhesive layer also exposes the end portion. A pump in the housing includes an actuator employing a shape memory alloy wire.
