Patent number: 7813779Abstract: 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.Type: GrantFiled: July 26, 2006Date of Patent: October 12, 2010Assignee: Nellcor Puritan Bennett LLCInventors: Don Hannula, Paul Mannheimer

Patent number: 7810359Abstract: A headband with a tension indicator having an elastic segment sized to fit around a wearer's head; and a non-elastic segment being 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, and the non-elastic segment is larger than the portion of the elastic segment it spans when the elastic segment is not stretched. The non-elastic segment is attached with the elastic segment in such a manner that the non-elastic segment projects out from the surface of the elastic portion when the headband is not sufficiently tight, thus creating a loop which provides a visual indication that the headband needs re-tightening.Type: GrantFiled: October 1, 2003Date of Patent: October 12, 2010Assignee: Nellcor Puritan Bennett LLCInventors: Don Hannula, Joseph Coakley

Patent number: 7698909Abstract: A headband having a low stretch segment sized to fit around a wearer's head, and an elastic segment being smaller than the low stretch segment, and having a free end and an attached end, where the elastic segment is attached at its attached end with the low stretch segment. The headband also includes a tab portion having a first end and a second end, the first end of the tab portion being connected with the free end of the elastic portion, the second end of the tab portion configured to form a closed loop with the low stretch segment, around the wearer's head. The headband also includes visual indicator configured for monitoring the extended position of elastic segment and optionally a stop portion that is configured to engage against the elastic segment to limit its stretch.Type: GrantFiled: February 13, 2004Date of Patent: April 20, 2010Assignee: Nellcor Puritan Bennett LLCInventors: Don Hannula, Joseph Coakley, Paul D.

Patent number: 7561905Abstract: 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.Type: GrantFiled: September 29, 2006Date of Patent: July 14, 2009Assignee: Nellcor Puritan Bennet LLCInventors: Russ Delonzor, Paul D.

Patent number: 7389130Abstract: 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.Type: GrantFiled: September 25, 2006Date of Patent: June 17, 2008Assignee: Nellcor Puritan Bennett Inc.Inventors: Russ Delonzor, Paul D.

Patent number: 7289837Abstract: 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.Type: GrantFiled: October 1, 2003Date of Patent: October 30, 2007Assignee: Nellcor Puritan Bennett IncorpoatedInventors: Paul D.

Publication number: 20070219440Abstract: The present invention provides non-adhesive oximeter sensors for patients with sensitive skin. Sensors of the present invention include a light emitting diode (LED) and a photodetector. The LED and the photodetector may be covered by a reflective mask and a faraday shield. Sensors of the present invention have a non-adhesive laminated layer. The non-adhesive layer contacts, but does not stick to, the patient's skin. When the sensor is removed from the patient, the non-adhesive layer does not tear or irritate the patient's skin. The non-adhesive layer preferably has a large static coefficient of friction. Sensors of the present invention can also have hook-and-loop layers. The sensor can be attached to the patient's body by wrapping the sensor around the patient and engaging the hook layer to the loop layer.Type: ApplicationFiled: March 7, 2007Publication date: September 20, 2007Applicant: Nellcor Puritan Bennett LLCInventors: Don Hannula, Paul Mannheimer
