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 enabling a user to activate the apparatus.
摘要:
A cartridge for a medication dispensing device which includes multiple septums. The cartridge includes a body and an axially shiftable piston in fluid-tight engagement with an interior surface of the body. The first septum covers a dispensing port that opens to an interior hollow of the body at a proximal location. The second septum covers a filling port that opens to the interior hollow. The first septum is arranged to be engaged by a dispensing conduit moving generally perpendicular to the axial direction for fluidly communicating with the interior hollow during a dispensing operation of the device. The second septum is arranged to be engaged by a filling conduit for fluidly communicating with the interior hollow during filling of the cartridge.
