Abstract:
1. An apparatus for subcutaneous self-administration of an injectable product comprising: a housing; a receiving sleeve coupled with the housing; an injection needle protruding beyond the housing; a needle protection sleeve generally surrounding the injection needle, the needle protection sleeve being connected to the housing and slideable between a proximal position and a distal position, wherein in the distal position the injection needle protrudes beyond the needle protection sleeve and a rear portion of the needle protection sleeve is disposed within an interior of the housing such that a user of the apparatus, when placing the needle protection sleeve on tissue and moving the needle protection sleeve from the proximal position to the distal position, cannot view the needle entering and penetrating the tissue and cannot gauge the relative position of the needle by monitoring the relative movement of the rear portion of the needle protection sleeve, and wherein in the proximal position the injection needle does not protrude beyond the needle protection sleeve; an indicator which visibly indicates to the user of the apparatus that the needle protection sleeve is in the distal position during insertion of the injection needle for administration of the injectable product, wherein the needle protection sleeve actuates the indicator; and a window on the housing, wherein the indicator comprises a slider including an optical marker visible through the window when the needle protection sleeve is in the distal position.
