Abstract: A zero-heat-flux DTT measurement device is constituted of a flexible substrate supporting an electrical circuit including a heater trace defining a heater, thermal sensors, and a thermal sensor calibration circuit.

Abstract: 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 with a plurality of contiguous sections. 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 sections. A heater trace is disposed on the first substrate section with the first thermal sensor. The first and second sections are folded together to position the first and second thermal sensors therebetween, and a flexible insulator disposed between the folded-together first and second sections maintains the first and second thermal sensors in a spaced-apart relationship.

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.

Abstract: A disposable, zero-heat-flux, deep tissue temperature probe is constructed using a support assembly with multiple sections folded together or separated into strata during assembly of the probe. The sections support elements of the probe, including thermal sensors and a thermal resistor between the thermal sensors. Optionally, one of the sections supports a heater.

Abstract: A thermal blanket for warming the limbs includes a surface, an inactive region of the surface adapted to lie against the thoracic and/or abdominal area of a person extending at least from the thighs to the abdomen of the person, active regions of the surface adapted to circulate pressurized air to limbs of the person, and an inflatable pneumatic structure adapted to distribute pressurized air to the active regions. When warmed, pressurized air is introduced into the pneumatic structure, prewarming and/or comfort warming is provided.

Abstract: A wound treatment apparatus is provided which includes a bandage that is transparent to, or transmissive of, energy in the infrared (IR) range of the electromagnetic spectrum, a heater that generates heat, and an attachment device for retaining the heater over or on the bandage. The bandage and heater together have a low profile so as to be convenient for a patient, and are flexible so as to conform to the shape of a wound and to contours of the skin near the wound. The bandage is provided with an adhesive pattern for maintaining moisture at the wound site. The heater may maintain a normothermic condition at the wound treatment area. A controller may be provided for cycling the temperature of the heater in order to maintain the normothermic condition.

Abstract: A tissue treatment apparatus includes a bandage that is transparent to, or transmissive of, energy in a predetermined range of the infrared (IR) portion of the electromagnetic spectrum. The bandage includes a layer that acts as a bandpass filter, permitting IR radiation in the range of wavelengths between 3 and 30 &mgr;m to pass through the bandage to tissue against which the bandage is disposed. A heater is used to generate heat, including IR radiation, and an attachment device retains the heater over or on the bandpass bandage layer. The bandage and heater together have a low profile so as to be convenient for a patient, and are flexible so as to conform to the shape of a wound and to contours of the skin near the wound. The bandage is provided with an adhesive pattern for maintaining moisture at the wound site. The heater may maintain a normothermic condition at subdermal regions of the wound treatment area.

Abstract: A method for testing/calibrating a system for performing single-breath carbon monoxide lung diffusing capacity measurements. By simulating a patient's lungs using a precision syringe for drawing a preanalysis gas mixture through the equipment (inspiration) and a modified scuba regulator valve or a solenoid valve with a purge button to simulate the expiration of a postanalysis gas through the system into a sampling chamber, the DL.sub.co measuring system performance can be assessed as a whole rather than as a collection of individual components.
