Geometry of a Transcutaneous Sensor
First Claim
1. A sensor to aid in diagnosing at least one of infiltration and extravasation in Animalia tissue, the sensor comprising:
- a housing including a surface configured to confront an epidermis of the Animalia tissue;
a first waveguide being configured to transmit a first light signal, the first waveguide being at least partially disposed in the housing and having an emitter end face configured to emit the first light signal that enters the Animalia tissue; and
a second waveguide being configured to transmit a second light signal, the second light signal including a portion of the first light signal that is at least one of reflected, scattered and redirected from the Animalia tissue, the second waveguide being at least partially disposed in the housing and having a detector end face configured to collect the second light signal that exits the Animalia tissue;
wherein the detector end face extends in a first narrow band along a first straight line, and the emitter end face is spaced a distance perpendicular to the first straight line.

Abstract
A transcutaneous electromagnetic signal sensor includes an emitter and a collector. The emitter includes an emitter end face configured to emit a first electromagnetic radiation signal that enters Animalia tissue. The collector includes a detector end face configured to collect a second electromagnetic radiation signal that exits the Animalia tissue. The second electromagnetic radiation signal includes a portion of the first electromagnetic radiation signal that is at least one of reflected, scattered and redirected from the Animalia tissue. The second electromagnetic radiation signal monitors anatomical changes over time in the Animalia tissue.
