Abstract:
1. A system for the therapeutic application of dry carbon dioxide gas comprising: an enclosure, where the enclosure comprises a door, a seat, and an aperture through which a user's neck may extend therethrough, where the aperture comprises a means of creating a seal between the enclosure and a user's neck, where a gas is contained within the enclosure; a means of circulating the gas contained within the enclosure; a source of carbon dioxide and a carbon dioxide valve, where the source of carbon dioxide is in fluid connection with the enclosure thereby allowing carbon dioxide to flow into the enclosure, where the carbon dioxide valve regulates the flow of carbon dioxide from the source of carbon dioxide into the enclosure; a humidifier, where the humidifier is operably connected to the enclosure and regulates moisture added into the enclosure; a heater, where the heater is operably connected to the enclosure thereby adding heat thereto; a carbon dioxide concentration sensor, where the carbon dioxide concentration sensor determines the concentration of carbon dioxide of the gas and generates a sensed carbon dioxide concentration value; a carbon dioxide flow sensor, where the carbon dioxide flow sensor determines the flow rate of carbon dioxide entering the enclosure and generates a sensed carbon dioxide flow value; a temperature sensor, where the temperature sensor determines the temperature of the air-gas mixture within the enclosure and generates a sensed temperature value; a humidity sensor, where the humidity sensor determines the humidity of the gas within the enclosure and generates a sensed humidity value; a timer, where the timer generates on and off values; a control circuit, where the control circuit controls the carbon dioxide valve, heater, and humidifier, where the control circuit accepts the values from the carbon dioxide concentration sensor, the carbon dioxide flow sensor, the temperature sensor, the humidity sensor, and the timer; a safety circuit, where the safety circuit, independent of the control circuit, controls the carbon dioxide valve, heater, and humidifier, where the safety circuit, independent of the control circuit, accepts the values from the carbon dioxide concentration sensor, the carbon dioxide flow sensor, the temperature sensor, and the humidity sensor; whereby a user may be substantially enclosed within the enclosure and subject to an environment wherein the temperature, humidity, and concentration of carbon dioxide are controlled.
