Abstract: A personal air filtration device and methods of using the same for providing a zone of filtered air proximate a breathing zone of a user are described. A blower provides an air flow to a head support which delivers the air flow to a zone proximate the users head. The air flow passes through a filter. The filter can be a point of delivery filter disposed about an air permeable surface of the head support. The delivered air flow can provide a laminar air flow defining a zone of filtered air about the user's breathing zone.

Abstract: A neck-worn personal air filtration device for providing a zone of filtered air around or near a user's breathing zone is described. The device comprises a blower, a hose, and a neck-worn plenum including a filter. Air blown from the blower, passes through the hose and into the plenum exiting the plenum. The air is filtered by a filter for breathing by the user.

Abstract: A multi-zone electric heating blanket. The blanket may be shaped to cover the outstretched arms or other body parts of a patient. The blanket includes first and second body part portions and a connecting bridge. The interconnection via the bridge leaves an open gap between the first and second body part portions for unblocked access to the patient. A power controller may supply power to heating elements in both body part portions based on a temperature sensor in one of the body part portions.

Abstract: Embodiments include a conformable heated mattress for patient warming during surgery. The mattress may include a base layer coupled to an operating table and a heated layer coupled to the base layer. The heated layer may include an electrical heating element. The heated layer is coupled to an opposing surface of the base layer at a portion of the opposing surface forming an attached area. The attached area is less than an area of the opposing surface allowing at least a portion of the heated layer to be folded substantially independently of the base layer. Embodiments also include a method of positioning a patient on such a heated mattress.

Abstract: Embodiments include a heating blanket. The heating blanket may include a heating element and a shell covering the heating element. The heating element has elastic properties and is disposed in the shape of a sheet. The shell may have one or more sheets of polymeric material bonded together adjacent a perimeter of the heating element. One or more wires having malleable properties are secured within the shell. The wires allow the heating blanket to be secured to a patient.

Abstract: Embodiments include a flexible fabric heater. The fabric heater has a conductive base fabric having elastic properties. The base fabric may be coupled to electrical terminals. A elastomeric layer may be applied on the base fabric. The elastomeric layer may have elastic properties and includes a liquid-resistant material. A first thermal layer may be applied proximate edges along the electrical coupling between the fabric heater and the electrical terminals. The first thermal layer can have heat-resistant properties.

Abstract: An electric blanket including a flexible sheet-like heating element, a shell comprising two flexible sheets covering the heating element, one or more welds coupling the sheet of the shell about the edges to hermetically seal the heating element there between; and a flexible insulating layer extending over the heating element and covered by the shell providing at least one of thermal insulation and electrical insulation, wherein the heating element is held in position between the two sheets of the shell without using connectors that pierce the two sheets.

Abstract: An electric heating blanket including a flexible sheet-like heating element and a shell. The shell covers the heating blanket and includes two sheets of flexible material welded together.

Abstract: An apparatus, a system, and a method for thermally comforting a patient include pneumatic, convective device providing thermal treatment for persons or animals, which is adapted for use in combination with a clinical garment such as a hospital gown, robe, bib, and other equivalents. The pneumatic convective device provides convective warming focused or directed primarily on the thorax or body core. The pneumatic convective device includes at least one inlet for being accessed through a clinical garment, a region in distribution with the inlet for distributing a stream of pressurized, thermally treated air, and a permeable member for emitting pressurized, thermally treated air from the distribution region.

Abstract: Devices, methods and systems for creating a zone of filtered air proximate a head of a user including an air filtration device including a blower being configured to be disposed within, below, or affixed to a bedding structure, an air plenum in flow communication with the blower and in support of the head of the user and having an air delivery surface configured to distribute the air flow to the zone of filtered air, and a filter disposed within the device for filtering the air flow before it is distributed to the zone of filtered air.

Abstract: A heat exchanger has a laminar fluid flow path receivable between the heating plates of a high flow rate infusion unit to which heat is conducted by contact with the heating plates. A bubble trap and a valve are integrated with the heat exchanger. The bubble trap collects air from the infusate exiting the laminar flow path, and includes an air vent in contact with the infusate that vents the air from the bubble trap. The valve shuts off the flow of infusate if air is detected in the bubble trap.

Abstract: A forced air warming unit has a casing with inlet and outlet openings. The casing encloses a scroll housing with a curved inside surface in which a blower is disposed. A circuit board in the casing encloses the blower in the scroll housing. At least one opening penetrates the circuit board. A heater plate is disposed between the circuit board and the blower. The blower draws air through the inlet opening, along a first side of the circuit board through the at least one opening into the scroll housing. The blower also forces air along a second side of the circuit board which faces the scroll housing, through air passages in the circuit board, along the first side through the at least one opening, into the scroll housing. The blower accelerates air along the curved inside surface and past the heater plate. Heated, pressurized air exits through the outlet opening.

Abstract: A heated underbody supports including heated mattresses, heated mattress overlays and heated pads, and methods of using heated underbody supports, for therapeutic warming. The heated underbody supports include a heater assembly and a layer of compressible support material. The heater assembly includes a flexible heating element , first and second bus bars, and a temperature sensor. The flexible heating element is a conductive fabric which can be adapted to stretch into a 3-dimensional compound curve without wrinkling or folding while maintain electrical conductivity, and wherein the heating element is adapted to return to the planar shape when pressure is removed. The flexible heating element may include a fabric which is coated with a conductive or semi-conductive polymer. The heated underbody support may also include a water resistant shell which may encase the heater assembly and the compressible support material.
