20150374822 | METHODS AND APPARATUS FOR THE ENHANCED DELIVERY OF THE PHYSIOLOGIC AGENTS TO TISSUE SURFACES - 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. | 12-31-2015 |
20150327793 | BREATH END-TIDAL GAS MONITOR - An improved apparatus and method for capturing and analyzing the end-tidal portion of an exhalation. The CO | 11-19-2015 |
20140194703 | BREATH SELECTION FOR ANALYSIS - Methods and systems are described to obtain and analyze a gas sample from a desired section of the breath of a person, while accounting for erratic, episodic or otherwise challenging breathing patterns that may otherwise make the capturing of a gas sample from the desired section of breath difficult. These techniques may provide more reliable, accurate and adequate samples of gas such as end-tidal gas, and ultimately an accurate analysis of the sample captured. | 07-10-2014 |
20140053835 | GAS DISPENSER WITH DIFFUSING NOSEPIECE - Described here are hand-held, low flow devices for dispensing a therapeutic gas. The devices may be configured to include a gas control assembly for delivering a defined volume of gas at a controlled pressure and flow rate. A nosepiece may be included in the device that is formed of a porous material capable of filtering the dispensed gas, and also diffusing the flow of gas as it travels through the nosepiece and into the nasal cavity. The nosepiece may be configured so that there is substantially no restriction of flow therethrough. Methods for treating various medical conditions and delivering therapeutic gases to the nasal mucosa using hand-held, low flow gas dispenser devices are also described. | 02-27-2014 |
20130331769 | METHODS FOR TREATING HEADACHES - 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. | 12-12-2013 |
20130165806 | COLLECTION AND ANALYSIS OF A VOLUME OF EXHALED GAS WITH COMPENSATION FOR THE FREQUENCY OF A BREATHING PARAMETER - Apparatuses are described to accurately determine a gas concentration of a sample of a patient's breath. The apparatuses may include a sample compartment, a breath speed analyzer, a gas analyzer, and a processor. The sample compartment includes an inlet that receives the breath. The breath speed analyzer determines the speed of a portion of the breath. The gas analyzer determines a gas concentration. The processor includes an algorithm that determines a degree of non-homogeneity of the sample based on the speed, and a corrected gas concentration based on the degree of non-homogeneity. In some variations, the gas correction is determined independently of patient cooperation. Apparatuses may be tuned based on the intended population's expected breathing pattern ranges such that the sample compartment is filled with a homogenous end-tidal gas sample regardless of an individual's breathing pattern. These apparatuses are useful, for example, for end-tidal CO analysis. Methods are also described. | 06-27-2013 |
20120150055 | BREATH END-TIDAL GAS MONITOR - An improved apparatus and method for capturing and analyzing the end-tidal portion of an exhalation. The CO | 06-14-2012 |
20120138053 | GAS DISPENSER FOR DISPENSING ACCURATE DOSES OF THERAPEUTIC GAS FROM A RESERVOIR CONTAINING HIGHLY COMPRESSED THERAPEUTIC GAS - Described here are devices for intranasally delivering therapeutic gases to a patient. The devices may include a measurement chamber, a combination of pressure regulators and a sequencing mechanism that controls valves associated with the pressure regulators. When implemented in a hand-held dispenser, the hand-held dispenser may reliably deliver consistent doses of gas regardless of the unknown state and pressure of the therapeutic gas in the measurement chamber. | 06-07-2012 |
20120097879 | COMPRESSED GAS CYLINDER WITH AN INTEGRAL VALVE - Described here are devices including gas cylinders for use in various applications. The applications may comprise the dispensing and administration of a compressed gas to the nasal mucosa of a user. The devices generally include an integral valve comprised of a valve seat and a valve pin. The orifice of the valve seat may be configured to limit the flow rate of the gas. | 04-26-2012 |
20120059311 | PORTABLE THERAPEUTIC GAS DISPENSING DEVICE - Described here are hand-held dispensers for intranasally delivering a therapeutic gas such as carbon dioxide to a user. The dispensers generally include a compressed gas cylinder, a pierce pin block, a valve, a regulator tube and a nosepiece. The regulator tube regulates both the pressure and flow of the gas out of the dispenser. | 03-08-2012 |
20110046546 | METHODS FOR TREATING HEADACHES - 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. | 02-24-2011 |
20110040240 | METHODS FOR TREATING RHINITIS AND CONJUNCTIVITIS - 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. | 02-17-2011 |
20100104665 | Methods and Apparatus for Treating Rhinitis - 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. | 04-29-2010 |
