Publication number: 20230263706Abstract: Single dose drug dosage form dispensing devices, and methods for operating such devices are disclosed herein. In one embodiment, an apparatus includes a housing defining an actuation pathway and a pusher. At least a portion of the pusher is disposed within the actuation pathway such that a distal end portion of the pusher and a distal end portion of the housing define a volume configured to contain a drug-containing tablet. The pusher is configured to move relative to the housing in a distal direction from a first position to a second position to expel the drug-containing tablet from the volume. The distal end portion of the pusher is extended from an opening in the housing when the pusher is in its second position. The housing is configured to limit movement of the pusher relative to the housing in a proximal direction from the second position of the pusher towards the first position of the pusher after the drug-containing tablet is expelled from the volume.Type: ApplicationFiled: May 1, 2023Publication date: August 24, 2023Inventors: Casidy Domingo, Edmond Chiu, Bradley Blackwood
