Abstract: A hand-held, low-flow dispenser comprises an enclosure holding a gas cartridge. A spring-biased needle is advanced to puncture a septum on the gas cartridge, and a separate spring-biased ball valve is used to turn the resulting gas flow off and on as well as to control the flow rate.

Abstract: The invention relates to methods for transcutaneous and transmucosal application of carbon dioxide in the form of a gas and in the form of a capnic solution (such as carbonated water) for the relief of pain, including musculoskeletal disorders, neuralgias, rhinitis and other ailments. Gaseous carbon dioxide is applied to the skin for at least three minutes, and the capnic solution may be held on the skin for at least three minutes, which provides relief of symptoms. The capnic solution may also be sprayed onto mucous membranes such as the nose for relief of symptoms such as allergic rhinitis.

Abstract: Apparatus and methods deliver treatment agents simultaneously with capnic gases. The capnic gases can enhance the effectiveness of the treatment agent for treating rhinitis, lower the dosage of drug or concentration of agent necessary to achieve a therapeutic result, or both. Exemplary capnic gases include carbon dioxide, nitric oxide, nitrous oxide, and dilute acid gases.

Abstract: Apparatus, methods, and kits for treating symptoms associated with common ailments, such as headaches, rhinitis, asthma, epilepsy, nervous disorders and the like, are provided. The apparatus comprises dispensers for carbon dioxide and other therapeutic gases. The methods comprise delivering small volumes of these gases to patients in a manner where the gas infuses into a body region in order to bathe the mucous membranes therein. It has been found that even very short exposure of patients to small volumes and high concentrations of such gases can provide significant relief from symptoms.

Abstract: Apparatus and methods deliver vasoconstrictive agents simultaneously with capnic gases. The capnic gases can enhance the effectiveness of the vasoconstrictive agent, lower the dosage of drug or concentration of agent necessary to achieve a therapeutic result, or both. Exemplary capnic gases include carbon dioxide, nitric oxide, nitrous oxide, and dilute acid gases.

Abstract: Apparatus and methods deliver physiologically active agents in the presence of adjuvant gases. The adjuvant gases can enhance the effectiveness of the drug, lower the dosage of drug or concentration of drug necessary to achieve a therapeutic result, or both. Exemplary adjuvant gases include carbon dioxide, nitric oxide, nitrous oxide, and dilute acid gases.
