ABSTRACT:
Warm air is distributed through a device and diffused along a person's body who is lying under a blanket. Warm air is supplied to the invention from a base unit that has various settings with respect to temperature of air supplied to the invention. The device has three distribution tubes that are long enough to extend from a person's feet to their upper torso while they are lying down. Heating takes place both conductively where the device is in contact with the patient and convectively where the warmed air circulates about the skin. The device is constructed from a light weight tissue paper that is plastic coated on one side and perforated at regular intervals. Heated air is supplied to the invention near the person's feet and is channeled to the several tubes toward the person's upper body. The heated air diffuses through perforations in the tubes as it moves up through the tubes and warms or maintains the body temperature of the patient. Blankets of varying tightnesses of weaves are placed over both the device and the patient thereby holding the desired amount of air near the patient while at the same time insulating against the exterior elements of the environment.
