Closed Circuit Forced Hot Air Intraoperative Patient Warmer With Improved Sterility

A system for closed circuit forced hot air warmer of patient beds and blankets with improved sterility, comprising:

• a) a sterilized blower with microprocessor controlled air heating capability having an input and an output opening, each opening being provided with a high-efficiency particulate air filter;
• b) said high-efficiency particulate air filters having pore openings less than 0.22 microns capable of filtering microbes and dust particles;
• c) said output opening of said sterilized blower being appointed to be connected to an input connection of a bed or blanket using a sterilized flexible hose with quick release connector;
• d) said bed or blanket having an output that is appointed to be connected to the input of said sterilized blower with a second sterilized flexible hose with quick release connector;
• e) said sterilized blower being appointed to circulate heated air within said bed or blanket, thereby forming a closed circuit without discharging said heated air into the area surrounding a patient or into an operating room;
• and
• f) an antimicrobial mist generator already containing or permitting the addition of an antimicrobial liquid for internal sterilization of said sterilized blower and sterilized flexible hoses, said antimicrobial mist generator having an input port and an output port;
• whereby said system for said closed circuit forced hot air warmer of patient beds and blankets with improved sterility prevents microbial contamination of said patient or of hospital workers by unsterile air currents generated by warm air circulating within the apparatus or released into the operating room.
