Non-invasive oximeter probe
First Claim
1. A noninvasive, electrooptical sensor probe for removable attachment to the skin of a patient to measure light extinction during transillumination of the blood-perfused tissue beneath the skin, comprising:
- a unitary elastomeric polymeric chassis having a topside and an underside and having a first end connected to a second end by a flexible bridge, whereby the topside of said first and second ends are spaced and opposed when the bridge is folded in a U-shape, and wherein the topside of at least one of said first or second ends forms a concave finger location saddle;
a light source mounted on the first end of said chassis;
a photosensor mounted on the second end of said chassis positioned to detect light emitted by said light source when the bridge is folded in a U-shape;
means for electrically connecting said light source and said photosensor to an external device; and
means for removably securing said chassis to the skin, wherein said means for removably securing said chassis comprises first and second wings extending from opposing lateral sides of one of first or second ends of said chassis.

Abstract
An improved noninvasive, electrooptical sensor probe is suitable for removable attachment to the skin of a patient to measure light extinction during transillumination of the blood-perfused tissue beneath the skin. According to the preferred embodiment of the probe, the probe has a unitary chassis having two widened ends connected by a flexible bridge. The topside of each widened end has a concave finger location saddle. The underside of the chassis has a cavity to receive an electrical sensor assembly including a light source and a photosensor. The probe further includes a foam backing having a front end connected to a back end by a neck, and two wings which extend laterally from opposing sides of the back end. The foam backing has an adhesive topside, which is bonded to the underside of the chassis to capture the electrical sensor assembly in the cavity of the chassis. Removable release tabs cover the adhesive topside of the wings prior to the application of the probe to a patient.
