Abstract
A method and device for sensing inhalations and controlling the delivery of oxygen or other therapeutic gases to a patient. A flow-through sensor is adapted to provide a method and device to monitor various parameters of a patient's breathing and/or pulse oxygen saturation. Adjustments are made to the bolus delivery from a source of therapeutic gas to efficiently provide appropriate levels of therapeutic gas to the patient and to economically conserve therapeutic gas.
Claims95
A therapeutic gas conserver and control device for a source of therapeutic gas comprised of:
- a supply valve having a first side, a second side, and a supply side, wherein said supply side of said supply valve is connected to said source of therapeutic gas;
- a flow-through sensor having a first side and a second side, wherein said second side of said sensor is connected to said first side of said supply valve;
- a cal valve having a first side and a vent side, wherein said first side of said cal valve is connected to said first side of said flow-through sensor;
- and the said vent side is open to atmospheric air;
- a patient outlet having a first side and a second side, wherein said first side of said patient outlet is connected to said second side of said supply valve;
- at least one cannula having a first side and a second side, wherein said first side of said at least one cannula is connected to said second side of said patient outlet;
- and
- a processor in electrical communication with said supply valve, said cal valve, and said flow-through sensor, wherein said processor provides a signal to control delivery of a portion of said source of therapeutic gas to a patient through said second side of said at least one cannula,
- wherein said device delivers therapeutic gas to a patient.
The device of claim-1 further comprising a supply compressor connected between said source of oxygen and said supply side of said supply valve, wherein said supply compressor raises the pressure of a supply of oxygen through said supply valve.
A therapeutic gas conserver and control device for a source of therapeutic gas comprised of:
- A therapeutic gas supply system;
- a flow-through sensor connected to said therapeutic gas supply system;
- a vent system connected to said flow-through sensor;
- and
- a processor in electrical communication with said therapeutic gas supply system, and said flow-through sensor, and said vent system.
A method of conserving and controlling the delivery of a source of therapeutic gas to a patient, the steps comprised of:
- providing a flow-through sensor in electrical communication with a processor;
- providing a therapeutic gas supply system in electrical communication with said processor;
- measuring at least one parameter of respiration of said patient;
- providing an algorithm for said processor to evaluate said measured at least one parameter of respiration;
- adjusting delivery of at least one bolus of therapeutic gas from said source of therapeutic gas to said patient in response to said evaluation of said at least one measured parameter of respiration.
A method of conserving and controlling the delivery of a source of therapeutic gas to a patient, the steps comprised of:
- providing a diaphragm-based sensor in electrical communication with a processor;
- providing a therapeutic gas supply system in electrical communication with said processor;
- measuring at least one parameter of respiration of said patient;
- providing an algorithm for said processor to evaluate said measured at least one parameter of respiration;
- adjusting delivery of at least one bolus of therapeutic gas from said source of therapeutic gas to said patient in response to said evaluation of said at least one measured parameter of respiration.
