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. |

DETAILED DESCRIPTION Accordingly, one aspect of the instant invention is to provide a securing mechanism for an optical probe capable of functioning in a wide variety of potential environments, including those which are hostile to adhesive-based, spring-tension-based, and/or hook-and-loop-based securing mechanisms.
The securing mechanism preferably comprises an elastic sock fitted with an optical probe.
According to one embodiment, the sock preferably conforms to a wearer's foot and comprises at least one toe portion.
The at least one toe portion is preferably positioned around the wearer's great toe or toes, such that the sock maintains a substantially opposing alignment of an emitter and a detector of the optical probe.
According to another embodiment, the sock preferably conforms to a wearer's hand and comprises at least one finger portion.
The at least one finger portion is preferably positioned around one or more of the wearer's three middle fingers, such that the sock maintains a substantially opposing alignment of an emitter and a detector of the optical probe.
According to another aspect of the invention, the sock may also advantageously be fitted with a manually activated timer circuit, preferably providing an alarm at predetermined intervals, such as those intervals associated with sequencing Apgar scoring.
Therefore, one aspect of the invention includes an optical probe positioner comprising a sock fitted with an optical probe wherein the optical probe measures at least one characteristic of tissue at a measurement site.
In addition, the sock comprises an elastomeric material such that the sock substantially conforms to a wearer's foot or hand, thereby forming a friction fit over a large surface area.
According to another aspect, the invention includes a method of securing an optical probe to tissue at a measurement site in order to determine a characteristic of the tissue.
The method comprises propositioning components of an optical probe in a sock such that single motion application of the sock to a measurement site is accomplished by pulling the sock over tissue at the measurement site
