APPARATUS FOR IMPROVED PULSE OXIMETRY MEASUREMENT

摘要

An apparatus for measuring the blood oxygen level of a patient is disclosed. In one embodiment, the apparatus includes a housing having an interior surface of non-reflective material substantially surrounding an interior. A cooperating light source and detector are operatively positined proximate the interior surface so as to emit and receive light projected within the interior of the housing. A material more conducive to light transmission, reflectance, or a combination thereof -as compared to the interior surface material- is positined proximate the light source and/or detector.
