Description

Electronic skin oximeter made of flexible, light, thin and bendable plastic

Technical Field

The utility model relates to a miniature electron biomedical equipment field, in particular to flexible frivolous flexible plastics's electron skin oximetry.

Background

Existing oximeters use Light Emitting Diodes (LEDs) to emit red and near infrared light through the skin and then detect how much light is on the other side. Red oxygen-rich blood absorbs more infrared light, while deeper oxygen-poor blood absorbs more red light. By observing the ratio of transmitted light, the sensor can determine how much oxygen is in the blood. These oximeters are only suitable for partially transparent body areas such as the fingertips or earlobes and can only measure the blood oxygen level at a single point of the body. "the forehead, arms and legs of the body are barely able to pass visible or near infrared light, which makes measuring oxygenation at these locations truly challenging.
