Patent number: 9351685Abstract: 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 he serially used to extend the useful life of the product.Type: GrantFiled: January 21, 2014Date of Patent: May 31, 2016Assignee: Covidien LPInventors: Michael Patrick O'Neil, Paul D. Mannheimer, Rodney Chin, Adnan I. Merchant, Joseph Coakley, Don Hannula

Patent number: 8649839Abstract: A non-invasive optical sensor which uses the motion signal to calculate the physiological characteristic being measured. For pulse oximetry, a least squares or a ratio-of-ratios technique can be applied to the motion signal itself. This is made possible by selecting a site on the patient where variations in motion produce signals of two wavelengths which are sufficiently correlated. In particular, it has been determined that a sensor placed on a nail, in particular a thumbnail, exhibits the characteristics of having the red and infrared signals correlated when used for pulse oximetry, and the resulting signals correlate to arterial oxygen saturation.Type: GrantFiled: June 24, 2010Date of Patent: February 11, 2014Assignee: Covidien LPInventors: Rodney Chin, Paul D Mannheimer, Ross Flewelling

Publication number: 20070260131Abstract: A clip-style pulse sensor may be adapted to apply limited, even pressure to a patient's tissue. A clip-style sensor is provided that reduces motion artifacts by exerting limited, uniform pressure to the patient tissue to reduce tissue exsanguination. Further, such a sensor provides a secure fit while avoiding discomfort for the wearer.Type: ApplicationFiled: May 2, 2006Publication date: November 8, 2007Inventor: Rodney Chin

Patent number: 7228161Abstract: A pulse oximetry sensor having a temperature indicator and a method of operating such a sensor to visually indicate to an operator the temperature of the sensor and hence a measure of the temperature of the tissue location to which the sensor is attached. In one embodiment, the temperature indicator is a color changing liquid crystal temperature monitor. The liquid crystal temperature monitor includes a number of segments, each of which is activateable within a predetermined temperature range to be monitored. In other embodiments of the present invention, the oximetry sensor includes an active regulated heating element to enhance blood perfusion within the tissue location being monitored. In either embodiment, the temperature indicator provides the operator with an effective way of monitoring the temperature of the sensor and the adjacent tissue location. In case of a heated sensor, the temperature indicator informs the operator that the warming function of the sensor is functioning correctly.Type: GrantFiled: December 17, 2004Date of Patent: June 5, 2007Assignee: Nellcor Puritan Bennett IncorporatedInventor: Rodney Chin
