Abstract: An apparatus for delivering a pharmaceutical liquid to a patient includes an outer casing; a needle cassette housed in the casing and containing a plurality of mutually parallel drug injection needles; a drug cartridge housed in the casing, containing a liquid and including a sealable aperture for accessing the liquid; a direct drive assembly housed in the casing and engageable with the drug cartridge to expel the liquid through the aperture; a lifter assembly housed in the casing and engageable with the needle cassette to drive one of the plurality of needles partially out of the casing and into a patient while simultaneously accessing the liquid in the drug cartridge through the sealable aperture and thereafter to withdraw the needle from the patient after a measured dose of the liquid has been adminstered; motor means in the casing for driving the direct drive assembly and the lifter mechanism; computer means for activating the direct drive assembly and the lifter mechanism; and, a control panel for enabli

Abstract: A medication dispensing apparatus that can be actuated with a small force to deliver a precise dose. The apparatus includes a fluid container having an injection chamber and a storage chamber in fluid flow communication. A first plunger is movable to alter the volume of the injection chamber, and a second plunger is movable to alter the volume of the storage chamber. The injection chamber has a cross-sectional area that is smaller than a cross-section area of the storage chamber. During dose setting, a drive assembly drivingly connected to the plungers shifts the plungers different distances so as to reduce the volume of the storage chamber while simultaneously increasing the volume of the injection chamber a similar amount. After dose setting, an actuator is movable with a small force to shift the first plunger to reduce the volume of the injection chamber to force medicine through an outlet of the fluid container.
