Abstract: A medication delivery pen includes a housing having opposing proximal and distal ends. An actuator is disposed in the proximal end of the housing for setting and administering a dosage of medication. The pen also includes a medication-containing cartridge assembly having a cartridge with a pierceably sealed distal end, an open proximal end removably attachable to the distal end of the housing, and a piston in sliding fluid tight engagement within the cartridge. A drive mechanism is coupled between the actuator and the cartridge to exert an axial force on the piston to inject the set dosage of medication. The actuator triggers the drive mechanism to administer the injection of medication held in the cartridge. A processor is coupled to the actuator to determine a value equal to the dosage set by the actuator. A memory device is coupled to the processor to store at least the dosage value determined by the processor.

Abstract: A universal cuff for a blood pressure monitor that has a usable length that is variable so that it can be used on a wide range of arm circumferences. The universal cuff includes a mechanism for setting the usable length having a shutoff cam and a D-ring. A blood pressure monitor is also presented having a mechanism for determining the usable length of the cuff by measuring inflation rate or by controlling a deflation rate control valve during deflation.
