A gas delivery apparatus configured for use with a mechanical ventilator having an atmospheric inlet for drawing in atmospheric gas includes a connecting device configured to connect to an oxygen supply and an air supply and to deliver mixed air and oxygen gas to the atmospheric inlet of the mechanical ventilator. The connecting device further includes a user control for adjusting a fraction of oxygen in the mixed air and oxygen gas. The connecting device comprises a reservoir configured to hold a volume of the mixed air and oxygen gas.

An anti-explosion gas generator for health use is provided. The anti-explosion gas generator for health use includes an electrolysis device for electrolyzing water to produce a gas mixture of hydrogen and oxygen. The gas generator for health use further includes a gas mixing system coupled to the electrolysis device for receiving the gas mixture. The gas mixing system mixes the gas mixture with water vapor, an atomized medicine, a volatile essential oil or a combination thereof to produce a health gas. The health gas is provided for being inhaled by a user.

A breathing circuit system for delivering gas from a fresh source to a user through a face mask. The system includes a cylindrical housing and a resiliently-biased valve supported substantially centrally within the housing. In the default or “off” position, the resilient bias causes the valve to be seated on a valve seat shutting off axial flow of gas through the valve housing. When the patient or user breathes, negative pressure is applied to one side of the valve effective to sufficiently overcome the resilient bias imposed on the valve to move the valve off the valve seat axially (or otherwise open in another direction) within the housing, thereby allowing flow of gas through both the valve seat and the valve housing, and into the breathing circuit connected thereto. When the patient's breathing pauses and begins to exhale, the valve bias returns the valve to its default or off condition shutting off flow of gas through the valve.

An apparatus and method for controlling the end tidal partial pressure of a gas X in a subject's lung, and to the use of such an apparatus and method for research, diagnostic and therapeutic purposes, wherein the method consists of: —obtaining input of a series of logistically attainable PetX values for a series of respective breaths: —determining an amount of gas X required to be inspired by the subject in an inspired gas to target the PetX for each of said respective breaths: and—controlling a gas delivery device to deliver the amount of gas in a volume of gas delivered to the subject in each of said respective breaths to target the respective PetX for that breath.

Therapy gas delivery systems that provide run-time-to-empty information to a user of the system and methods for administering therapeutic gas to a patient. The therapeutic gas delivery system may include a gas pressure sensor attachable to a therapeutic gas source that communicates therapeutic gas pressure data to a therapeutic gas delivery system controller, a gas temperature sensor positioned to measure gas temperature in the therapeutic gas source that communicates therapeutic gas temperature data to the therapeutic gas delivery system controller, at least one flow controller that communicates therapeutic gas flow rate data to the therapeutic gas delivery system controller, at least one flow sensor that communicates flow rate data to the therapeutic gas delivery system controller, and at least one display that communicates run-time-to-empty to a user of the therapeutic gas delivery system. The therapeutic gas delivery system controller of the system includes a processor that executes an algorithm to calculate the run-time-to-empty from the data received from the gas pressure sensor, temperature sensor, flow controller and flow sensor, and directs the result to the display.

The present invention relates to a device and method of delivering inhaled Nitric Oxide (iNO) to a patient situated in a Magnetic Resonance Imaging (MRI) suite.

A hydrogen mixed gas generation method using a device that includes a heating pipe housing therein a reduction acceleration member and a heating part including a heating device that heats the heating pipe includes a first process and a second process. The first process includes: causing raw water to flow into the heating pipe and heating the flowing raw water to generate water vapor; heating the generated water vapor to between 500° C. to 800° C.; causing the heated water vapor to be in contact with the reduction acceleration member that is heated along with the raw water to reduce the water vapor and generate hydrogen gas. The second process includes: diluting the hydrogen gas generated in the first process to obtain hydrogen mixed gas whose concentration of hydrogen gas is between 500 ppm to 20000 ppm.

A ventilator system includes a first air tank, a plurality of second air tanks communicated with the first air tank, a plurality of breathing devices respectively communicated with the second air tanks, a plurality of first vacuum tanks respectively communicated with the breathing devices, and a second vacuum tank communicated with the first vacuum tanks. The first air tank has a positive pressure relative to the second air tanks. The second vacuum tank has a negative pressure relative to the first vacuum tanks.

A system for deliverying a therapeutic amount of nitric oxide can include a reservoir assembly, a gas supply, and a delivery conduit including a first cartridge, wherein the first cartridge can include a surface-activated material saturated with an aqueous solution of a reducing agent.
