Publication number: 20040267104Abstract: 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: ApplicationFiled: June 25, 2003Publication date: December 30, 2004Applicant: Nellcor Puritan Bennett Inc.Inventors: Don Hannula, Paul Mannheimer

Publication number: 20040221370Abstract: 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: ApplicationFiled: February 13, 2004Publication date: November 11, 2004Applicant: Nellcor Puritan Bennett IncorporatedInventors: Don Hannula, Joseph Coakley, Paul D. Mannheimer

Publication number: 20040199063Abstract: 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 re-attachment to a patient's skin. The independent pieces of the adhesive layers can be serially used to extend the useful life of the product.Type: ApplicationFiled: April 23, 2004Publication date: October 7, 2004Applicant: Nellcor Puritan Bennett Inc.Inventors: Michael Patrick O'Neil, Paul Mannheimer, Rodney Chin, Adnan Merchant, Joseph Coakley, Don Hannula

Patent number: 6763255Abstract: 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: July 12, 2002Date of Patent: July 13, 2004Assignee: Nellcor Puritan Bennett IncorporatedInventors: Russ DeLonzor, Paul D. Mannheimer, Michael E. Fein, Don Hannula

Publication number: 20040117891Abstract: 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: ApplicationFiled: October 1, 2003Publication date: June 24, 2004Applicant: Nellcor Puritan Bennett IncorporatedInventors: Don Hannula, Joseph Coakley

Patent number: 6112107Abstract: A flexible sensor with strain relief on electrical contacts. Wires are attached to the electrical contacts, then a bulge of material is deposited over them, such as an adhesive. The wires are then bent back over the top of the bulge and secured. This prevents any tugging on the cable from pulling directly on the attachment of the wires to the contacts.Type: GrantFiled: December 1, 1998Date of Patent: August 29, 2000Assignee: Nellcor Puritan Bennett IncorporatedInventor: Don Hannula
