Abstract

A positioner, such as an elastic sock, is fitted with an optical probe, preferably designed for pulse oximetry. The sock preferably substantially forms to the shape of a wearer's foot or hand. In addition, the sock preferably comprises at least one positioning portion. According to one embodiment, the positioning portion is configured to receive at least a wearer's great toe, thumb, or finger, such that the sock maintains substantially opposing alignment of an emitter and a detector. Alternatively, the positioner may comprise a toecap, a glove, or a mitten. The positioner may also advantageously be fitted with a timer circuit, preferably providing an alarm at predetermined intervals.
