Abstract
A medication delivery device, for use with a container having a distal end and a needle being placed at the distal end of the container, including: a push rod which is movable with respect to at least a portion of the container; a resilient member configured to bias the push rod to move toward the distal end of the container; a releasable restraining means configured to releasably restrain the push rod in a locked state against the biasing of the resilient member; a means to adjust amount of movement of the push rod with respect to the container in order to deliver a predetermined dose of medication; and an activation means configured to release the releasable means. The means to adjust amount of movement of the push rod with respect to the container is bi-directional. The device can accommodate containers of different size or shape.
