Abstract

An improved medicant delivery system is disclosed wherein the carrier for the medicant is a fluid that can be atomized or vaporized by exposure to heat. The system provides for repeatable dose of medicant, can be stored in any orientation, and/or has an ability to maximize energy efficiency.

Claims

1. A control system for a hand-held vapor delivery device, comprising:

a circuit configured to

provide a precise amount of power from a power source to heat a heating element to a minimum required temperature to completely vaporize a precise volume of a liquid, and control a precise duration of time to supply the precise amount of power to completely vaporize the predetermined volume of liquid at the required temperature;

monitor a temperature of the heating element while the power is being supplied;

compare the temperature of the heating element to the minimum required temperature; and

adjust the precise duration of time or the precise amount of power based on the comparison step to completely vaporize the liquid, wherein if the precise volume of liquid is adjusted, the precise duration of time or the precise amount of power is adjusted to completely vaporize the adjusted precise volume of liquid within a new minimum required temperature for a new minimum required time.

2. The control system of claim 1, wherein the circuit comprises a one-shot circuit.

3. The control system of claim 1, wherein the circuit further comprises a processor programmed to monitor a resistance of the heating element and adjust the amount of power to a level sufficient to heat the heating element to the required temperature.

4. The control system of claim 1, wherein the circuit comprises a DC/DC boost converter and a supercapacitor operatively connected to the power source to adjust the amount of power to the level sufficient to heat the heating element to the required temperature.

5. The control system of claim 1, wherein the circuit is configured to actuate the power source a predetermined number of times.

6. A control system for a hand-held vapor delivery device, comprising:

a. a means for providing a precise amount of power from a power source to heat a heating element to a minimum required temperature to completely vaporize a precise volume of a liquid; and

b. a means for controlling a precise duration of time to supply the precise amount of power to completely vaporize the predetermined volume of liquid at the required temperature, wherein the precise duration of time or the precise amount of power is adjusted based on a comparison of a temperature of the heating element to the minimum required temperature to completely vaporize the liquid, wherein if the precise volume of liquid is adjusted, the precise duration of time or the precise amount of power is adjusted to completely vaporize the adjusted precise volume of liquid within a new minimum required temperature for a new minimum required time.
