Abstract: A pulse oximeter sensor comprising an emitter and a detector disposed on a substrate layer with a thinned portion between the emitter and the detector. A partially transparent covering layer covers the substrate layer and comprises a corresponding thinned portion. The thinned portions attenuate light shunted via the substrate layer and the partially transparent covering layer from the emitter to the detector, and may be configured such that less than 10% of the light detectable by the detector is shunted light.

Abstract: A pulse oximeter sensor comprising a light emitter and a detector disposed on a substrate layer with a plurality of perforations or variations in thickness between the light emitter and the detector. The plurality of perforations or variations in thickness blocks or scatters light shunted via the substrate layer from the light emitter to the detector, and may be configured such that less than 10% of the light detectable by the detector is shunted light.

Abstract: A pulse oximeter sensor comprising an emitter and a detector coupled to a substrate layer and a partially opaque layer located on a patient contact side of the sensor and covering the emitter. The partially opaque layer is configured to attenuate light shunted via the partially opaque layer from the emitter to the detector, and may be configured such that less than 10% of the light detected by the detector is shunted light.

Abstract: A pulse oximeter sensor having an emitter(s) and a detector, with a layer having a first portion of the emitter and a second portion of layer over the detector is provided. A barrier is included between the first and second portions of the overlying layer to substantially block radiation of the wavelengths emitted by the emitter(s). Preferably, the barrier reduces the radiation shunted to less than 10% of the radiation detected, and more preferably to less than 1% of the radiation detected.

Abstract: Forehead oximetry sensor devices and methods for determining physiological parameters using forehead oximetry sensors. One method includes placing an oximetry sensor on the forehead of a patient, such that the sensor is placed on the lower forehead region, above the eyebrow with the sensor optics placed lateral of the iris and proximal the temple; and operating the pulse oximeter to obtain the physiological parameter. In one aspect, the method also includes providing and placing a headband over the oximetry sensor, or alternately, the sensor is a headband-integrated sensor. The headband has an elastic segment sized to fit around the patient's head. The headband also includes a non-elastic segment that is smaller than and attached with the elastic segment. The non-elastic segment is sized to span a portion of the elastic segment when the elastic segment is stretched. In addition, the non-elastic segment is larger than the portion of the elastic segment it spans when the elastic segment is not stretched.

Abstract: An optical sensor having a cover layer, an emitter disposed on a first side of the cover, a detector disposed on the first side of said cover, and a plurality of stacked independent adhesive layers disposed on the same first side of the cover, wherein the top most exposed adhesive layer is attached to a patient's skin. Thus, when the sensor is removed to perform a site check of the tissue location, one of the adhesive layers may also be removed and discarded, exposing a fresh adhesive surface below for reattachment to a patient's skin. The independent pieces of the adhesive layers can be serially used to extend the useful life of the product.

Abstract: A method for use and an improved oximeter sensor substrate that is conforming to the shape of the patient's forehead. In one embodiment, the present invention is an oximeter sensor, having a substrate with a shape similar to a shape of at least a portion of a patient's forehead and including a section adapted to substantially fit over a portion of a forehead of a patient; an emitter disposed on the substrate at a position located on the section; and a detector disposed on the substrate at a distance from the emitter. In one embodiment, the substrate includes a hat that holds the emitter and the detector in a spaced-part manner against the patient's forehead.
