1. A portable substance inhalation system comprising:
- a mixing flask;
at least a first inhalation chamber in fluid communication with the mixing flask;
at least a second inhalation chamber in fluid communication with the mixing flask;
a cart with a plural of wheels attached;
a heater thermally coupled to the mixing flask;
at least one test fluid reservoir in fluid communication with the mixing flask;
at least one air source in fluid communication with the mixing flask;
a pump in fluid communication with the test fluid reservoir and the mixing flask;
wherein a test vapor can be selectively and individually provided to the first inhalation chamber and the second inhalation chamber; and
wherein the first inhalation chamber and the second inhalation chamber can be selectively removed from the substance inhalation system without test vapor leaking therefrom;
wherein air from the air source is mixed with a test fluid from the test fluid reservoir within the mixing flask;
wherein the pump is used to pump test fluid from the test fluid reservoir to the mixing flask; and
wherein the mixing flask, the first inhalation chamber, and the second inhalation chamber are placed on the cart.

Abstract
A substance inhalation system includes a mixing flask that is in fluid communication with plural inhalation chambers. A test vapor can be selectively and individually provided to the inhalation chambers. Moreover, individual inhalation chambers can be selectively removed from the substance inhalation system without test vapor leaking from any of the inhalation chambers.

11. An inhalation chamber lid assembly for enclosing an inhalation chamber, the inhalation chamber lid assembly comprising:
-
a lid plate; at least one disconnect fitting installed in the lid plate; at least one latch attached to the lid plate; a gasket placed between the lid plate and the inhalation chamber; at least one rubber plug removably installed within the lid plate; at least one thumb screw threadably engaged with the lid plate; wherein the disconnect fitting includes a one-way valve incorporated therein; wherein a fluid line can be disconnected from the disconnect fitting without a test vapor leaking; wherein the latch securely fastens the inhalation chamber lid assembly to the inhalation chamber; wherein the gasket seals the inhalation chamber; wherein the rubber plug is removable to provide access to the inhalation chamber; and wherein the thumb screw can be loosened to vent the inhalation chamber. - View Dependent Claims (12, 13)

14. A substance inhalation system comprising:
-
a mixing flask; a test fluid reservoir in fluid communication with the mixing flask; at least a first inhalation chamber in fluid communication with the mixing flask; at least a second inhalation chamber in fluid communication with the mixing flask; at least a first flow meter/controller in fluid communication with the mixing flask and the first inhalation chamber; at least a second flow meter/controller in fluid communication with the mixing flask and the second inhalation chamber; a heater thermally coupled to the mixing flask; a temperature sensor thermally coupled to the mixing flask; and a microprocessor electronically connected to the first flow meter/controller and the second flow meter/controller, the microprocessor including logic for selectively and individually controlling the flow of test vapor to the first inhalation chamber and the second inhalation chamber, determining whether a test parameter is within a predetermined range; and at least partially based thereon, altering the flow of test vapors to the first inhalation chamber or the second inhalation chamber, and determining whether a temperature within the mixing flask is within a predetermined operating range, and at least partially based thereon, adjusting the heater. - View Dependent Claims (15)
