Abstract: A medication delivery device, such as a pen-type injector, jet injector, medication pump, inhaler, spray or the like has a microprocessor coupled to the device that records the date, the time, and the amount of each medication administration. The microprocessor may also be coupled to a display to indicate the amount of medication to be administered. The medication delivery device can also be coupled with a blood characteristic monitor to analyze characteristics of the blood. This provides a single, all-in-one device that performs a variety of functions, and requires only a minimum of space. The medication delivery device may also use a disposable needle that substantially eliminates or reduces bleeding from an opening in the skin at the injection site.

Abstract: A medication injection mechanism, for delivering a dosage of medication from a medication cartridge having a piston, includes a two-piece drive shaft, a rachet mechanism, and a drive mechanism. The two-piece drive shaft includes a plunger portion and a drive portion. The plunger portion has an end that contacts the piston of the medication cartridge, ratchet teeth disposed on the sides of the plunger portion that define a thickness of the plunger portion, and an opening to provide a passage through the plunger portion of the two-piece drive shaft. The drive portion is formed by rails that are coupled together by a connector that passes through the opening in the plunger portion so that the drive portion is coupled to the plunger portion, and can move relative to the plunger portion. Each of the rails forming the drive portion has threads on a surface that extend beyond the defined thickness of the plunger portion.
