TISSUE MONITORING APPARATUS AND METHOD
First Claim
1. An apparatus for monitoring a subject'"'"'s tissue, the apparatus comprising:
- a light emitter adapted to emit light through tissue in the subject'"'"'s head;
a light detector adapted to detect light emitted from the light emitter and scattered by the tissue of the subject'"'"'s head;
a probe adapted to be inserted into an orifice of the subject'"'"'s head, the probe including one of the light emitter and the light detector; and
a controller in communication with the light detector and light emitter and adapted to detect an oxygenation level of blood in the subject'"'"'s head based upon measurements of the scattered light detected by the light detector.

Abstract
A tissue monitoring device includes a light emitter, a light detector, a probe, and a controller. The light emitter emits light through tissue in the subject, such as tissues in the subject'"'"'s head. The light detector detects light emitted from the light emitter and scattered by the subject'"'"'s tissue. The probe is inserted into an orifice of the subject and includes one of the light emitter and light detector. The controller communicates with the light detector and the light emitter and detects an oxygenation level of the blood in the subject'"'"'s tissue based upon measurements of the scattered light. The probe may include one or more bladders for blocking ambient light and/or for ensuring contact exists between the light detector (or emitter) and an interior surface of the subject'"'"'s orifice.

12. An apparatus for monitoring a subject'"'"'s tissue, the apparatus comprising:
-
a first light emitter adapted to emit light through tissue in the subject'"'"'s head; a second light emitter adapted to emit light though tissue in the subject'"'"'s head; a light detector adapted to detect light emitted from the first and second light emitters and scattered by the tissue of the subject'"'"'s head; a probe adapted to be inserted into an orifice of the subject'"'"'s head, the probe including one of;
(1) the first and second light emitters, and (2) the light detector; anda controller in communication with the light detector and the first and second light emitters and adapted to synchronize readings taken from the light detector with light emissions emitted by the first and second light emitters to thereby monitor a state of the subject'"'"'s tissue. - View Dependent Claims (13, 14, 15, 16, 17)

18. An apparatus for monitoring a subject'"'"'s tissue, the apparatus comprising:
-
a first unit having first and second light emitters adapted to emit light through a first region of the subject'"'"'s head; a second unit having third and fourth light emitters adapted to emit light though a second region of the subject'"'"'s head; a first probe adapted to be inserted into a first ear canal of the subject, the first probe including a first light detector adapted to detect light emitted from the first and second light emitters and scattered by the first region of the subject'"'"'s head, the first probe also including a first temperature sensor; a second probe adapted to be inserted into a second ear canal of the subject, the second probe including a second light detector adapted to detect light emitted from the third and fourth light emitters and scattered by the second region of the subject'"'"'s head, the second probe also including a second temperature sensor; and a controller in communication with the first and second light detectors and adapted to detect an oxygenation level of blood in the first region of the subject'"'"'s head based upon measurements of the scattered light detected by the first light detector, to detect an oxygenation level of blood in the second region of the subject'"'"'s head based upon measurements of the scattered light detected by the second light detector, and to compare temperature readings from the first and second temperature sensors. - View Dependent Claims (19, 20)
