Physiological parameter monitoring apparatus
First Claim
1. A tissue oximeter sensor, comprising:
- a substrate with a non-zero finite depth and first and second major sides, wherein at least a first material free region extends along the depth from one of the sides to the other of the two sides forming a first well in the substrate, and one of the sides of the substrate is configured to be removeably affixed to a human or animal subject; and
a first channel with first and second end portions, wherein one of the end portions of the first channel is selectively positioned in the first well along the depth alternatively at one of a plurality of different depth positions and the end portion does not extend beyond the first well on the side configured to be affixed to the subject, and the first channel routes radiation at least one of from the first end portion to the second end portion or from the second end portion to the first end portion.

Abstract
A tissue oximeter sensor includes a substrate with a non-zero finite depth and first and second major sides. At least a first material free region extends along the depth from one of the sides to the other of the two sides forming a first well in the substrate. One of the sides of the substrate is configured to be removeably affixed to a human or animal subject. The sensor also includes a first channel with first and second end portions. One of the end portions of the first channel is selectively positioned in the first well along the depth alternatively at one of a plurality of different depth positions. The first channel routes radiation at least one of from the first end portion to the second end portion or from the second end portion to the first end portion.

26. A physiological parameter monitoring apparatus, comprising:
-
a processing unit, including an optical source and an optical detector; flexible optical transmit and receive channels having first and second end regions; and a flexible substrate that carries the first end regions of the flexible optical transmit and receive channels, wherein the first end regions are installed at predetermined depths of the flexible substrate, the installed depths correspond to a tissue oximetry processing algorithm of the processing unit, the flexible optical transmit channel routes optical radiation emitted by a source from the second end region of the flexible optical transmit channel to a target adjacent the first end region, and the flexible optical receive channel routes optical radiation traversing or reflecting from the target to the detector, wherein the first end region does not extend beyond the substrate on a side configured to be affixed to the subject.
