AU2018200051B2 — Devices, systems and methods for medicament delivery

USPTO Abstract

An apparatus, comprising: a housing defining a cavity configured to receive a medicament container, the medicament container containing a medicament, the medicament container coupled to a needle that is disposed within a lumen of a needle sheath; a delivery mechanism disposed within the housing, the delivery mechanism configured to produce a force to move the medicament container within the housing from a first container position to a second container position and to deliver the medicament from the medicament container to a target location when the medicament container is in the second container position within the cavity of the housing, the needle being disposed within the housing when the medicament container is in the first container position, the needle being disposed through an opening defined by the housing when the medicament container is in the second container position; a contact member coupled to a distal end portion of the housing, the contact member including a contact surface configured to contact the target location, the contact member configured to move relative to the distal end portion of the housing from a first position to a second position; a retraction mechanism configured to retract the needle after delivery of the medicament such that the needle is disposed within the housing when the needle is retracted; and an electronic circuit system coupled to the housing, the electronic circuit system configured to output a first light output when the needle sheath is removed from about the needle such that the needle is outside of the lumen of the needle sheath, the electronic circuit system configured to output a second light output when the contact member moves from the first position to the second position.
