ABSTRACT:
A multi-use pen-shaped medication dispensing device made of a plastic material that is recyclable after the contents of the medication cartridge have been exhausted. The device is made of a minimal number of parts, which include a housing, a dial assembly, a generally cylindrical button assembly located within the proximal end of the dial assembly, an internally threaded nut, and an externally threaded leadscrew. The device is arranged so that the dial must be rotated to the zero dose position prior to setting a dose. The device includes a lockout mechanism that prevents the dial from being depressed during dosing. The device further includes a mechanism that limits the maximum dosage that can be dialed up and a mechanism that prevents the user from dialing up a dosage greater than that remaining in the cartridge.
