초록 ▼

An apparatus for monitoring and controlling the flow of a therapeutic gas to a patient. The apparatus includes a gas source, a flow management module and an electronics module. The flow management module contains a valve assembly and a sensor. The valve assembly contains a first valve to control the inflow of the therapeutic gas. The second valve controls the inflow of ambient air. When the valve assembly is deenergized the first valve is open allowing the flow of gas through the apparatus. The second valve is closed. When the valve assembly is energized, the first valve is closed stopping the flow of gas and the second valve is open allowing the inflow of ambient air. The sensor senses changes in the flow of the gas or ambient air and transmits a signal to the electronics module. The electronics module can be preprogrammed to control the valve assembly, determine respiratory rate, control the flow of therapeutic gas, store or transmit data in response to signals sent by the sensor.

A monitoring system for periodically detecting the flow of a therapeutic gas from a gas source to a patient, comprising: a gas source for providing a therapeutic gas; a flow management module operatively connected to the gas source, said flow management module containing a valve assembly and a sensor; an electronics module operatively connected to the sensor; means for delivering the therapeutic gas no a patient; said valve assembly further comprising a first valve positioned between the gas source, the sensor, and the breathing patient, and a second valve positioned between an ambient airport, the sensor, and the breathing patient, said valve assembly having an energized state wherein said first valve is in an open position and said second valve is in a closed position; the sensor having means for detecting a flow of the therapeutic gas or a flow of ambient air through the valve assembly and independently to the breathing patient; the sensor further comprising means for sending a signal to the electronics module in response to the flow of the therapeutic gas or the flow of ambient air; said electronics module logs, displays, and/or transmits the flow of the therapeutic gas or the flow of ambient air through the valve assembly; said electronics module further having means for determining a presence, rate and strength of inhalations based upon the flow of ambient air through the valve assembly and to the breathing patient, when the valve assembly is in said energized state; said electronics module further having means for activating or deactivating said gas source in response to its determination of the rate of inhalations of the patient of ambient air; said electronic modules further comprising means for activating or deactivating the gas source in response to a predetermined pattern of inhalations or a predetermined pattern of interruptions in a flow of the ambient air through the valve assembly and to the breathing patient; and wherein said predetermined pattern of inhalations and predetermined pattern of interruptions in the flow of ambient air prevent an improper activation of the gas source or an improper deactivation of the gas source.
