Infant warming and sensor mat
First Claim
1. An infant warming and sensor mat comprising:
- a compressible layer for supporting the weight of an infant patient;
a plurality of light sources;
a sensor layer having a plurality of light detectors contained therein;
a cover layer, wherein said cover layer overlays said sensor layer, and allows passage of light therethrough;
at least one of said plurality of light sources being oriented to transmit light through said cover layer to a patient supported by said compressible layer;
a computer processor in communication with said plurality of light detectors; and
wherein, when a patient is placed upon said mat, at least one of said plurality of light sources and at least one of said plurality of light detectors cooperate with said computer processor to calculate a hemoglobin oxygen saturation level of the patient based on an amount of said light reflected from the patient.

Abstract
An infant warming and sensor mat for keeping a baby warm and monitoring the baby'"'"'s haemoglobin oxygen saturation level (SaO2) and heart rate. The mat preferably comprises a bottom layer of compressible padding material, a sensor layer comprising a plurality of light sources and light detectors, a cover layer having multiple openings, and an air layer between the sensor layer and cover layer. Warm air supplied to the air layer escapes through the openings in the cover to warm the baby. The light sources shine light of an appropriate wavelength onto the baby through the openings in the cover, and the light detectors sense the amount of light reflected back from the baby, which is indicative of SaO2 level. Heart rate is also determined from the resulting periodic signal.
