Abstract: A tuckable electric warming blanket for patient warming and a method of using such a warming blanket. The blanket may be used to warm the lower body of the patient or other portion of the patient's body. The blanket may include one or more rigid stays that extend along the right and left sides of the blanket. The stays assist in fully tucking the blanket under the patient and reduce the potential for bunching up the heating element under the patient. The blanket may also include a flexible, unheated foot portion that is tuckable about the patient's feet.

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

Abstract: A blanket for warming patients during surgery and other medical procedures. The blanket includes one or more temperature sensors and a shut-off timer to prevent prolonged exposure of excessive heat to a patient. Embodiments of the present invention provide a safety feature that cuts power to a heating blanket after a certain period of time has elapsed, irrespective of the feedback provided by a temperature sensor concerning the blanket temperature. That period of time is longer than it takes for the blanket to reach its threshold temperature but shorter than it takes to cause thermal burn injury.
