Patent number: 10274383Abstract: A zero-heat-flux, deep tissue temperature measurement system measures internal body temperature by way of a probe having a heater and thermal sensors arranged in a zero-heat-flux construction. The measurement system includes control mechanization that determines heater and skin temperatures based upon data obtained from the probe and uses those temperatures to calculate a deep tissue temperature. The measurement system includes a signal interface cable having a connector where a probe can be releasably connected to the system. The cable and attached connector are a removable and replaceable part of the system, separate from the probe. The measurement system provides an output signal imitating a standard input signal configuration used by other equipment.Type: GrantFiled: April 28, 2016Date of Patent: April 30, 2019Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Mark T. Bieberich, Philip G. Dion, Gary L. Hansen, David R. Palchak, Timothy J. Prachar, Ryan J. Staab, Albert P. Van Duren, Elecia White, Allen H. Ziaimehr

Patent number: 9310257Abstract: Disposable, zero-heat-flux, deep tissue temperature probes are constructed using a support assembly constituted of a flexible substrate that supports elements of the probe. One support assembly embodiment includes a folded substrate with a heater and thermal sensors disposed on it. Another support assembly includes multiple sections separable into strata supporting a covering guard heater, a central thermal sensor, and a thermal sensor displaced at least radially from the central thermal sensor.Type: GrantFiled: April 14, 2010Date of Patent: April 12, 2016Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Mark T.

Publication number: 20150335470Abstract: A warming device includes a clinical garment with a flexible inflatable convective apparatus integrated with or supported on a surface of the garment for warming one or more limbs when the apparatus is inflated with warmed air. The convective apparatus includes a central member, one or more peripheral diffusers, and one or more flexible ducts. In some cases, each duct connects a diffuser with the central member. One or more inlet ports are provided in the convective apparatus to receive the end of an air hose. The central member is inflatable in response to a flow of air through an inlet port. A peripheral diffuser is positioned on the clinical garment so as to be deployable to or near to an extremity such as a limb. When a peripheral diffuser is deployed while the central member is inflated with warmed air, the warmed air flows from the central member, through a duct to the peripheral diffuser and is emitted through an air-permeable wall of the diffuser to warm the extremity.Type: ApplicationFiled: October 30, 2013Publication date: November 26, 2015Inventors: Carol J. Panser, Albert P. Van Duren

Patent number: 8801282Abstract: The invention pertains to flexible devices used for zero-heat-flux, deep tissue temperature measurement, especially to disposable temperature measurement devices. Such a device is constituted of a flexible substrate. An electrical circuit is disposed on a side of the substrate. The electrical circuit includes first and second thermal sensors disposed, respectively, on first and second substrate layers. A heater trace is disposed on the first substrate layer with the first thermal sensor. The first and second substrate layers are separated by a flexible layer of insulation disposed between the first and second substrate layers. The heater trace defines a heater with a central portion that operates with a first power density and a peripheral portion around the central portion that operates with a second power density greater than the first power density.Type: GrantFiled: September 13, 2012Date of Patent: August 12, 2014Assignee: 3M Innovative Properties CompanyInventors: Mark T.
