1. A hand-held medicant delivery device, comprising:
- a. a housing having a first end and a second end;
b. a fluid delivery system, comprising;
i. a fluid reservoir inside the housing, the fluid reservoir having a proximal end and a distal end, andii. a pressure generator positioned inside the fluid reservoir at the proximal end and configured to advance towards the distal end at a fixed and discrete distance to consistently meter a precise volume of a liquid from the fluid reservoir, wherein the pressure generator comprises a piston housed inside the fluid reservoir configured to push the liquid towards the distal end;
a fluid discharge actuator operatively connected to the piston, wherein each actuation of the fluid discharge actuator advances the piston closer to the distal end by the fixed and discrete distance;
a drive nut having a mating female screw thread operatively connected to the fluid discharge actuator wherein actuation of the fluid discharge actuator causes the drive nut to rotate a fixed rotational movement; and
a plunger operatively connected to the drive nut and the piston, such that the fixed rotational movement of the drive nut advances the plunger through the drive nut into the piston causing the piston to advance the fixed and discrete distance towards the distal end, wherein the plunger is threaded;
c. a cap operatively connected to the distal end of the fluid delivery system;
d. a vaporization system, comprising a heating element adjacent to the cap; and
e. a control system to deliver power to the vaporization system.
