Abstract: Underbody supports and related methods for supporting and restricting a sliding motion of a patient on a table. Certain embodiments of the underbody support may include two side walls, two end walls, a base layer, a compressible material layer opposite the base layer. The compressible material layer may be bonded to the two side walls and the two end walls about a perimeter of the compressible material layer to form a box-like structure that surrounds one or more inflatable chambers. The underbody support may further include one or more friction enhancing elements that are arranged to be interposed between the upper surface of the compressible material layer and the patient when the patient is being supported on the underbody support to prevent sliding of the patient.

Abstract: Apparatus and methods related to a non-invasive core temperature monitor for monitoring the temperature of a patient. In certain embodiments, the monitor may include a heated underbody support for heating at least a portion of a patient. The heated underbody support may include a low thermal mass heater and a temperature sensor. The heater may heat the peripheral thermal compartment of the patient to a temperature that is greater than the core temperature of the patient. The monitor may reduce the temperature of the low thermal mass heater to a set-point temperature that is less than the core temperature, allowing the temperature of the low thermal mass heater to move towards being in thermal equilibrium with the core body temperature. The core temperature may be determined when the peripheral thermal compartment of the patient is in substantial thermal equilibrium with the temperature of the core thermal compartment of the patient.

At least one of the inflatable chambers may include one or more compression sensitive switches for monitoring the volume of the inflatable chamber, and the one or more compression sensitive switches may be located within the inflatable chamber. In some embodiments the one or more compression sensitive switches are sized to close when the said inflatable chamber is deflated to a desired residual volume.

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: System, methods and apparatus related to surgical sponges and surgical sponge counting and detection systems. The system, methods and apparatus may include features such as a Radio Frequency Identification (RFID) scanner adapted to detect entry and exit of a surgical sponge RFID identifier associated with each of a plurality of surgical sponges. In addition, an Electronic Article Surveillance (EAS) scanner may be included that is adapted to detect the presence of a surgical sponge having an EAS identifier associated with each of the plurality of surgical sponges. A control circuit may be configured to determine and provide an indication that all the sponges have been removed from the patient, or that one or more sponges still remain in the patient.

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 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.
