15. A wearable medicator suitable for controlled subcutaneous dispensing of liquid medication into a patient which comprises:
-
(a) a frame adapted for removable attachment to a patient; (b) a substantially rigid arcuate barrel for containing a supply of the liquid medication removably mounted on the frame, the barrel having an open end and an opposite end terminating in a dispensing nozzle; (c) a piston slidably and sealingly received within the barrel; (d) an elongated stem extending from the barrel and having one end in contact with the piston for moving the piston along the barrel, a side, and an arcuate shape permitting the stem to be received within the barrel;
the stem together with the piston comprising a plunger;(e) a connector means attached to the dispensing nozzle for introducing the liquid medication into the patient; (f) a rotatable spindle mounted on the frame, the spindle engaging the stem to drive the stem into the barrel so as to move the piston along the barrel; (g) motor means to rotate the spindle; and (h) control means associated with the motor means to control the operation of the plunger. - View Dependent Claims (16, 17, 18)
