Bio-mask with integral sensors
First Claim
1. 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;
a support bar connected to the forehead support and extending in generally lateral directions from the forehead support to define a pair of sensor sites on said forehead support, with one of the pair of sensor sites being proximate to a FP1 standard electrode placement position of a patient and the other of the pair of sensor sites being proximate to a FP2standard electrode placement position of said patient;
a pair of EEG sensors at ends of said support bar, with one of the pair of EEG sensors being held by the support bar at said FP1 standard electrode placement position and the other of the pair of EEG sensors being held by the support bar at said FP2 standard electrode placement position;
a control system adapted to receive a signal from said pair of EEG sensors, said control system determining said patient'"'"'s sleep stage based at least in part on said signal; and
a gas delivery device in communication with said control system, wherein said control system is adapted to adjust a gas delivery setting based upon a control system determination of said patient'"'"'s sleep stage, such that said gas delivery device delivers gas to the patient based on the control system determination of said patient'"'"'s sleep stage.

Abstract
A system including a mask to detect an EEG signal and to deliver a gas, the mask having a forehead support extending from the body and adapted to contact a forehead surface of the patient during use, the forehead support having a plurality of sensors located thereon for detecting electrophysiological signals of the patient, with the plurality of sensors including EEG sensors positioned proximate to FP1/FP2 standard electrode placement positions of the patient, a gas delivery device in fluid communication with the mask and having an adjustable gas output, and a control system for determining a sleep stage from EEG signals detected by the mask and adjusting a gas delivery device based on the sleep stage.

17. A method of delivering gas comprising:
-
providing a mask adapted to detect an EEG signal and to deliver a gas, the mask comprising a mask body having an internal surface, an external surface, and a perimeter surface; providing 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, with at least one of said plurality of sensors being a first EEG sensor positioned proximate to a FP1 standard electrode placement position of said patient and a second of said plurality of sensors being a second EEG sensor positioned proximate to a FP2 standard electrode placement position of said patient; providing a gas delivery device in fluid communication with the mask and having an adjustable gas output; determining a sleep stage from EEG signals detected by the mask; and adjusting the output from the gas delivery device based on the sleep stage, by the use of a control system adapted to adjust a gas delivery setting based upon a determined sleep stage. - View Dependent Claims (18, 19, 20, 21)
