Abstract: Provided is a respiratory monitoring device that measures and outputs the substantial use time of an oxygen supply device. A respiratory monitoring device (4) used in combination with an oxygen supply device (1) delivering highly concentrated oxygen gas includes a detection unit (6) that detects a change in breathing-related information representing at least one of a pressure, a flow rate, and a gas temperature, based on exhalation and inhalation, a calculation unit (725) that calculates a respiratory rate, based on the change in breathing-related information, a determination unit (726) that determines whether breathing is present, and whether a user of the oxygen supply device is present, based on the respiratory rate, a measurement unit (727) that measures a duration in which a user of an oxygen supply device has been determined to be present, based on a determination result obtained by the determination unit, and an output unit (728) that outputs a cumulative measurement result for the duration.

Abstract: An oxygen concentrator is provided with a controller for recovering an oxygen concentration to a level suitable for treatment in a short period of time by selecting an optimum purge time corresponding to the deterioration state of an adsorbent. The judgment of moisture-absorption deterioration is performed when the detected value of the oxygen concentration sensor is equal to or less than a control value of the oxygen concentration in the oxygen-enriched gas and the detected value of the pressure sensor is equal to or more than an adsorption pressure at which the oxygen concentration increases significantly before and after the control to reduce the purge time, and control of reducing a time for the purge step shorter than a preset time is performed.

Abstract: Provided is a respiratory rate measurement device (4), the respiratory rate measurement device (4) including a detection unit (6) that detects an in-tube pressure and/or an in-tube gas flow rate in a tube (2) supplying concentrated oxygen gas to a patient from a pressure swing adsorption oxygen concentration device (1) connected to the patient and concentrating oxygen in the air by periodically repeating pressurization and depressurization, and outputs pressure data and/or gas flow rate data, an arithmetic operation unit (722) that extracts patient respiratory information data, based on the pressure data and/or the gas flow rate data, and an estimation unit (723) that estimates a respiratory rate per predetermined time, based on the patient respiratory information data, wherein the estimation unit (723) estimates the respiratory rate using, as a respiratory interval, a time ?t in which the autocorrelation coefficient takes a peak.

Abstract: Provided is an oxygen concentration device, a control method, and a control program with which a start-up interval until a desired high-concentration oxygen gas can be supplied can be reduced. The oxygen concentration device includes a pressurized air supply unit for supplying pressurized air, an adsorption tube which concentrates oxygen in the pressurized air by adsorbing nitrogen in the supplied pressurized air to generate oxygen gas, an oxygen gas tank for storing oxygen gas, a flow rate adjustment unit which adjusts an oxygen gas flow rate to be output to the exterior from the oxygen gas tank, and a control unit which controls the flow rate adjustment unit so that the oxygen gas flow rate becomes a set flow rate and controls the pressurized air supply unit so that the pressurized air achieves a supply amount corresponding to the set flow rate.

Abstract: Provided is an oxygen concentrator provided with a control means for recovering an oxygen concentration to a level suitable for treatment in an extremely short period of time by selecting an optimum purge time corresponding to the deterioration state of an adsorbent, wherein judgment of moisture-absorption deterioration is performed when the detected value of the oxygen concentration sensor is equal to or less than a control value of the oxygen concentration in the oxygen-enriched gas and the detected value of the pressure sensor is equal to or more than an adsorption pressure at which the oxygen concentration increases significantly before and after the control to reduce the purge time, and control of reducing a time for the purge step shorter than a preset time is performed.

Abstract: The present invention provides an oxygen concentrator which allows the flow rate setting to be changed safely and securely by the patient using a remote control device, the oxygen concentrator comprising a control means which does not allow the operation of the flow rate setting change button unless the remote control device receives the information on the flow rate setting value of the oxygen-enriched gas supplied by the current oxygen concentrator main body.
