Wesco thermal temperature management system, based on low voltage conductive ink technology is a disposable patient warming device for use in medical critical care settings. 

Invented by Arlen West, with the counsel of the former chief of staff of OSF hospitals in Peoria, Illinois, Robert Hart, MD and the current chief of hyperbaric medicine of the US Navy, the Wesco technology produces a stable, low voltage heat source currently unavailable in the operating room or other critical care settings.  The technology addresses the serious potential health risks of unstable temperature management, leading to swifter patient healing, lower risk of infection and elimination of hypothermia related disorders. In addition to the healthcare system savings due to shorter hospital stays, the disposable warming device offers significant cost advantages compared with alternative options and can be conveniently stored and operated, satisfying requirements of hospitals and other critical care settings.

The conductive ink heating element is incorporated into a blanket and can be designed for neonate to adult use. Draped with a non-woven polypropylene material which meets class 1 flammability requirements, the blanket is disposable, flexible, light weight and convenient for use by the care-giver based on power service options.  Disposability makes it ideal for medical applications where blood and bodily fluids are prevalent and fresh blankets are easily employed in the OR, recovery, etc.

Wesco has received two US patents and one Canadian patent.
