Abstract
Vaporization of volatile materials while avoiding combustion and denaturation of such material provide an alternative to combustion as means of volatilizing bioactive and flavor compounds to make such compounds available for inhalation without generating toxic or carcinogenic substances that are by-products of combustion and pyrolysis.
Claims10
A device for vaporization and delivery of a volatile source material without combustion or significant denaturation of the source material comprising, in combination, (i) a heating system including a means for heating and a heating chamber, (ii) a source material holder which is insertable in and removable from the heating chamber, and (iii) a temperature control means which maintains the temperature of operation of the heating system substantially constant within a range of about .+-.10.degree. C. both when the material holder is in the heating chamber and when it is removed from the heating chamber during use,
- wherein the heating system comprises an electrical resistance heater in a metal body which is of sufficient mass to maintain the + or -10.degree. C. temperature range and which has at least one air flow hole and is connected to a pump means which forces air through the air flow hole at an air flow rate of between about 0.5 and 5 liter per min.
A device for delivering multiple volatile source materials which vaporize at different temperatures by means of inhalation, which comprises (i) a high thermal mass heating system having at least one air flow hole extending therethrough and including a heating chamber and a temperature sensor;
- (ii) a volatile source material holder which fits within the chamber in the heating system, and (iii) a temperature controller.
- wherein the heating system comprises an electrical resistance heater in a metal body which is of sufficiently large mass that it can maintain a + or -10.degree. C. temperature range both when the volatile source material holder is within the heating chamber and when it is not within the heating chamber, and wherein the air flow hole is connected to an air pump which forces air through the air flow hole at an air flow rate of between about 0.5 and 5 liter/min.
