  • Publication number: 20170095619
    Abstract: A container for delivering a medicament to a target location includes a housing having a proximal end and a distal end, the housing including a cap locking tab at the distal end, and a vial containing medicament. The container includes a plunger slidable within the vial from the proximal end to the distal end of the vial to dispel the medicament, an injection member associated with the distal end, such that medicament dispelled from the vial passes through the injection member to the target location, and a slidable interaction member associated with the distal end of the vial configured to slide with the vial. An interaction between the slidable interaction member and cap locking tab causes the cap locking tabs to bias outward, and placement of a safety cap on the container after use locks the safety cap onto the container via the interaction with the cap locking tabs.

  • Patent number: 7438719
    Abstract: A phototherapy system and device is disclosed, including an array of light sources from at least two distinct spectral light regions. The first spectral light region represents the treatment color, and thus is chosen for its phototherapeutic value. For instance, blue light may be the treatment color for hyperbilirubinemia. The second spectral light region represents the balancing color, and is chosen for its ability to mitigate discomfort that may be caused by viewing the treatment color. When blue is the treatment color, yellow has been found to be an effective balancing color.
