Abstract
An injector device assembly and a method for making an injector device assembly are provided. The injector assembly includes a sterile insertion set with a housing and a hollow cannula and a device housing. A plunger is slidably received within the device housing for movement between an advanced position and a retracted position wherein the cannula is transcutaneously placed upon movement of the plunger from the advanced position to the retracted position. The device housing has a forward end defining a surface of placement against the skin of a patient with the device housing in a predetermined orientation relative to the patient'"'"'s skin. The injector device assembly includes a spring for urging the plunger toward the advanced position and a releasable cover member covering the forward end. The cover member and the device housing assure sterile conditions of the insertion set within the device housing prior to removal of the cover member.
