    摘要: A system for a closed circuit forced hot air warmer of patient beds and blankets with improved sterility has a patient mattress or blanket microprocessor controlled warmer that circulates heated air in a closed system without releasing warmed air into the area surrounding the patient or into the operating room. The system helps to avoid the exposure of patients and hospital workers in the operating room to possible infecting microbes carried in unsterile turbulent air currents related to the release of air from non-closed systems. The machinery and flexible hoses of the system are initially sterilized by a microprocessor controlled antimicrobial mist generator. The system does not discharge jets of warmed air due to the closed circuit arrangement. Turbulent air flow previously produced in the vicinity of the patient by high velocity air jets is eliminated. An ambient, quiescent condition accorded by closed circuit heating prevents infection of patients and operating room personnel by microbe migration.

    摘要: A multi-layered therapy pad is provided having a comfortable and supportive structure that houses heat therapy and electrotherapy means for treating back injuries and sores while an individual lies thereon. The pad comprises a first and second outermost layer of low-resilience polyurethane foam sandwiching an internal layer of higher density foam, which also supports electrical connections between the therapy controller, the power source, and the two therapy means within the pad. The electrotherapy means comprises static or tethered electrodes that apply pulsing electric current directly onto the user's back for stimulation and easing of back pain, while the heat therapy is applied using a resistance heating element within the pad, which heats a majority of the pad for applying heat to the user's back. The operation of the therapy means is controlled by an external controller, while power in received through an external source or an internal battery pack.
