Non-invasive oximeter probe

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, molded 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;
• 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 seconded wings having at least one adhesive side, wherein said first and second wings extend from opposing lateral sides of one of said first or second ends of said chassis.

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, molded elastomeric polymeric chassis having a nonadhesive 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;
• an electrical sensor assembly including a light source and a photosensor, said sensor assembly being mounted on said chassis whereby said light source is at said first end of said chassis and said photosensor is at said second end of said chassis, and wherein said photosensor is 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 the means for removably securing said chassis to the skin comprises a first and second flexible wing, wherein said first wing extends Laterally from one side of one of said first and second ends of said chassis, wherein said second wing extends laterally from the other side of said one of said first and second ends of said chassis, wherein said wings have a topside and an underside, wherein the topside side of said wings faces the same direction as the topside of the chassis, and wherein said underside of said wings is adhesive.
