Abstract
Modular physiological sensors that are physically and/or electrically configured to share a measurement site for the comfort of the patient and/or to ensure proper operation of the sensors without interference from the other sensors. The modular aspect is realized by providing outer housing shapes that generally conform to other physiological sensors; mounting areas for attachment of one sensor to another sensor; providing release liners on the overlapping sensor attachment areas; and/or providing notches, tabs or other mechanical features that provide for the proper placement and interaction of the sensors.

23. A modular physiological sensor comprising:
-
an electroencephalogram (EEG) sensor comprising a stem, a left branch, and a right branch, the left branch and the right branch extending generally perpendicularly from the stem so as to form a branch intersection, wherein the branch intersection includes a left corner defined by an intersection of the left branch and the stem of the EEG sensor and a right corner defined by an intersection of the right branch and the stem of the EEG sensor; a plurality of EEG electrodes disposed along the left branch and the right branch; a ground electrode and a reference electrode disposed proximate the branch intersection; a first mounting zone extending along an edge of the left corner of the branch intersection and configured for removable attachment of a first portion of a first regional oximetry (rO2) sensor; and a second mounting zone extending along an edge of the right corner of the branch intersection and configured for removable attachment of a first portion of a second rO2 sensor. - View Dependent Claims (24, 25, 26, 27, 28, 29)

30. A method of attaching a modular physiological sensor to a patient, the method comprising:
-
attaching an electroencephalogram (EEG) sensor on a forehead tissue site, the EEG sensor comprising a stem, a left branch, and a right branch, wherein the left branch and the right branch extend generally perpendicularly from the stem so as to form a branch intersection, the branch intersection including a left corner defined by the intersection of the left branch and the stem of the EEG sensor and a right corner defined by the intersection of the right branch and the stem of the EEG sensor, the EEG sensor further comprising a first mounting zone extending along an edge of the left corner of the branch intersection; and attaching a first portion of a first regional oximetry sensor to the first mounting zone of the EEG sensor. - View Dependent Claims (31, 32, 33, 34, 35, 36)

37. A modular physiological sensor comprising:
-
an electrical sensor configured to passively measure an EEG signal, the electrical sensor comprising a generally T shape including a first mounting zone positioned adjacent to an edge of a left corner of a left side of a vertical middle of the T shape and a second mounting zone positioned adjacent to an edge of a right corner of a right side of the vertical middle of the T shape; an optical sensor configured to detect an oxygen saturation, the optical sensor comprising a plurality of notches along a perimeter of the first portion of the optical sensor, wherein each of the plurality of notches extends from the perimeter of the first portion of the optical sensor inwardly toward an interior of the optical sensor; and wherein at least one of the first mounting zone and the second mounting zone includes a plurality of notch markings configured to align with the plurality of notches of the optical sensor when the first portion of the optical sensor is attached to either the first or second mounting zone. - View Dependent Claims (38, 39, 40, 41, 42)
