Claim:
1. An apparatus for removably retaining a unidose cartridge and dispensing at least one compound from the unidose cartridge, the apparatus comprising: a. a dispensing pen having a circumferential wall with an exterior surface and an interior surface, a rear interior chamber surrounded by a portion of an interior surface housing a source of electrical power electrically connected to an electric motor which in turn includes a rotatable shaft connected to a gear assembly, the gear assembly also connected to a moving shaft; b. the moving shaft having a multiplicity of teeth thereon extending from a distal end of the moving shaft to a proximal end of the moving shaft, the multiplicity of teeth engaging mating teeth of a connecting block which in turn is connected to a proximal end of an advancing shaft which extends though the dispensing pen to the unidose cartridge retaining chamber in a front of the dispensing pen; c. a pre-programmable printed electric circuit board connected to a first activation member and to a second activation member, the electric motor connected to the pre-programmable circuit board, when the first activation member is activated, the electric motor is activated, the gear assembly is activated and causes rotational motion of the moving shaft which in turn rotates the teeth on the moving shaft which engages the teeth on the connecting block which in turn moves the connecting block in a direction toward the front of the dispensing pen and concurrently causes the advancing shaft to move toward the front of the dispensing pen; and d. the dispensing pen including the unidose cartridge retaining chamber located between an interior dividing wall and a front of the dispensing pen, the unidose cartridge retaining chamber surrounded by a portion of the interior surface of the dispensing pen and the exterior wall of the dispensing pen, an interior dividing wall separating the advancing shaft and the movement shaft from the unidose cartridge retaining chamber, the dispensing pen including a front wall with a front opening.
