Abstract
A gas mask for use with associated monitoring and controlling apparatus is provided. A device for monitoring of patients with sleep disorders, breathing disorders or for anesthesia is provided. Different types of sensors on or in the mask and straps or caps connected to the mask include but are not limited to oximetery sensors, patient position sensors, eye movement sensors, leak detection sensors, EEG, EMG, EOG, ECG, PTT, microphones, pulse, blood pressure, oxygen saturation, temperature, movement sensors, position sensors, light sensors, leak detection sensors and gas delivery sensors. Another application provides for gas delivery to a bio-mask controlled, in part, via communication from a pacemaker to a bio-mask controller.
Claims32
A mask assembly comprising:
- a body having an internal surface, an external surface, and a perimeter surface;
- and
- a forehead support connected to the body, the forehead support having an EEG sensor located thereon.
A gas delivery system comprising:
- a mask having at least one physiological sensor connected thereto;
- a gas delivery device having an adjustable gas delivery setting;
- and
- a processor in communication with the gas delivery device and the sensor, the processor adapted to determine the existence of a sleep disorder and to adjust the gas delivery setting based thereon.
A gas delivery system comprising:
- a mask having at least one EEG sensor connected thereto;
- a gas delivery device having an adjustable gas delivery setting;
- and
- a processor in communication with the gas delivery device and the EEG sensor, the processor adapted to determine arousal and to adjust the gas delivery setting based thereon.
A method of delivering gas comprising:
- providing a mask adapted to detect physiological signals and to deliver a gas;
- providing a gas delivery device in fluid communication with the mask and having an adjustable gas output;
- determining a sleep state from physiological signals detected by the mask;
- and
- adjusting the output from the gas delivery device based on the sleep state.
A method of obtaining SPO2 reading from a mask comprising:
- attaching a light source and a light sensor on a mask so that the light source and light sensor are positioned to contact a person's forehead;
- illuminating the light source;
- detecting light from the light source as it deflects from the person's skull;
- and
- converting the detected light into an analog signal.
A method of detecting oral or nasal breathing during nasal ventilation, the method comprising:
- providing a mask adapted to form a seal between a patient's nose and mouth, the mask having an interior surface and an exterior surface, the mask also having a first thermal sensor on the interior surface and a second thermal sensor located on the exterior surface to be adjacent the patient's mouth;
- detecting a temperature change in the first or second thermal sensor.
An apparatus comprising:
- a mask having a body position sensor attached thereto;
- a processor in communication with the sensor and adapted to a determine body position from the body position sensor's output.
A method of detecting a leak in a breathing mask:
- providing a mask having a perimeter surface with a plurality of thermally conductive surfaces distributed throughout the perimeter surface;
- and
- detecting a temperature change in any of the plurality of thermally conductive surfaces.
A mask assembly comprising:
- a body having an internal surface, an external surface, and a perimeter surface;
- and
- a forehead support extending from the body and adapted to contact a forehead surface of a patient during use, the forehead support having a plurality of sensors located thereon for detecting electrophysiological signals of the patient.
A gas delivery system comprising:
- a gas mask adapted to fit on a patient;
- a gas delivery device having an adjustable gas delivery;
- and
- a processor in communication with the gas delivery device and a cardiac pacemaker, the processor adapted to adjust the gas delivery based on a signal from the cardiac pacemaker.
