- an upper assembly including a housing having a cavity, and a needle disposed in said upper assembly;
a lower assembly includinga receptacle member having an opening configured for accommodating insertion of the housing of the upper assembly, anda base member having an upper body and a recess formed on a top surface of the upper body for receiving the receptacle member; and
a base pad having an adhesive layer disposed on a lower surface of the pad, and being at least partially attached to a bottom side of the base member;
a biasing member disposed in said receptacle member and engaging said housing for biasing said housing away from said base member; and
a locking mechanism configured for releasably securing said housing in said lower position, said locking mechanism including at least one lower locking tab disposed on the receptacle member, and at least one corresponding upper locking tab disposed on the housing, such that when the tabs are in engagement, the housing is held in said lower position;
wherein the lower assembly is attached to a skin of the user using the base pad, and as the upper assembly is urged by a pressing force by the user from an upper position to a lower position relative to the lower assembly and overcoming force exerted by the biasing member, in the lower position, the needle disposed in the upper assembly travels downwardly to penetrate the skin for facilitating administration of the medicinal substance.

Abstract
A medical delivery device is provided for delivering a medicinal substance into a user'"'"'s body. An upper assembly includes a housing having a cavity configured for accommodating a needle. A lower assembly includes a receptacle member having an opening configured for accommodating insertion of the upper assembly, and a base member having an upper body and a recess formed on a top surface of the upper body for receiving the receptacle member. A base pad has an adhesive layer disposed on a lower surface of the pad, and being at least partially attached to a bottom side of the base member. The lower assembly is attached to a skin of the user using the base pad. As the upper assembly transitions from an upper position to a lower position relative to the lower assembly, the needle travels downwardly to penetrate the skin for facilitating administration of the medicinal substance.
