    摘要: A combination patient-transfer and intraoperative heater device has a top and bottom chamber separated by a barrier. The patient rests on the top chamber, which has a plurality of apertures for discharge of temperature-controlled filtered heated or cooled air at a regulated pressure for patient comfort and mitigation of infection. Heated or cooled filtered air is delivered to the area surrounding the patient, maintaining body temperature during anaesthesia. The bottom chamber has a plurality of apertures. When air pressure is low or off, the bottom chamber is flat and un-inflated. When air pressure is increased, air enters the bottom chamber and the apertures emit air, creating an air cushion facilitating lateral movement of the lifter device. The device performs two functions that now require separate devices and air blowers, it saves space and reduces both costs and complexity in the operating room while mitigating risk of infection.

    摘要: A sanitizing face mask inhibits the transmission of pathogens in air respired through the nose and mouth of a wearer. The mask includes hydrophobic inner and outer layers and an intermediate layer enclosed between them. The intermediate layer is saturated with a sanitizing liquid such as an ethanol solution. Respired air encounters the sanitizing liquid as it passes through the intermediate layer, killing pathogens borne on droplets or aerosols. The sanitizing mask protects the wearer, from pathogens in the inspired air, and others, from possible pathogens in the expired air of the wearer.

    摘要: A combination patient-transfer air-inflated pad and intraoperative heater device has first and second interlocking chambers laterally fused together. The air-inflated pad has a top surface and a bottom surface formed by way of the first and second interlocking chambers. The first interlocking chamber is formed as a comb-type structure having a main spine with two or more prongs alternately separated by valleys. The second interlocking chamber is a mirror comb-type structure to the first interlocking chamber. The device is fabricated from two thin layers of plastic material, selectively configured and fused. With this construction, the bulk of the device, as well as the cost of manufacture, are reduced. The device is affordable for single use, obviating the difficulty and possible incompleteness of sterilization between uses. The first interlocking chamber has an inlet appointed to be supplied with regulated, controlled low pressure and controlled temperature heated or cooled air. The second interlocking chamber has a plurality of air venting apertures in said bottom surface of said air-inflated pad. The second interlocking chamber has an inlet appointed to be supplied with ambient air at a regulated, controlled pressure to facilitate lifting and lateral displacement during patient transfer. The device may be easily re-employed when the patient is transferred from one location to another and may function as an alternating pressure mattress if needed.

    摘要: A mist generator is a standalone device that improves the internal sterility of controlled forced air systems. Sterilizing mist is generated when forced air circulates above or through a liquid disinfectant. The disinfectant is taken up into the circulating air and distributed throughout the internal structure of the system, sterilizing its internal surfaces. The mist generator contains no ionizers, atomizers, ultraviolet lamps, or other electric or mechanical devices.In one embodiment, the mist generator has a chamber with an inlet adapted for attachment to a blower or duct delivering forced air into the chamber. The chamber also includes an output duct or aperture adapted for attachment to a second hose which, in turn, is adapted for attachment to the inlet of the blower for delivery of disinfectant-misted air through internal components of the blower. Alternatively, there is used a disinfectant filter formed as a sterilizing grid having a screen coated with a soft porous surface material impregnated with a liquid disinfectant. The soft porous surface material releases said liquid disinfectant when forced air moves through the filter and through the system. In both embodiments, sterile water can be introduced to take up residual disinfectant and the vapor is captured in a dry filter or desiccant material and removed from the system.In the alternative embodiment, the sterilizing mist produced by the uptake of liquid disinfectant into circulating air and distributed throughout the forced air system can be formed when air from a blower or air handler is circulated across a sterilizing screen with a porous surface material impregnated with a liquid disinfectant. The antimicrobial mist is distributed throughout the system and acts to disinfect the internal surfaces and components. Additional water may be added to the sterilizing screen and distributed similarly by the forced air. A dry, desiccating filter, remote from the blower, traps the water and any residual disinfectant as it exits from the system. A dehumidifier, if installed, may also be used to remove water and can be readily emptied.The mist generator improves the sterility of the blower and mitigates microbial contamination of forced-air delivery systems.

    摘要: An air mattress has a top chamber and a bottom chamber separated by a barrier. The patient rests on the top surface of the top chamber, which has a plurality of apertures discharging air through apertures that are not blocked by the patient. The top chamber is provided with temperature-controlled heated or cooled air at a regulated pressure. Heated or cooled air from the top chamber is delivered to an area substantially surrounding the patient. The bottom chamber has a bottom surface containing a plurality of apertures that remain closed due to the weight of the mattress and the patient when the pressure-regulated air is beneath a pre-selected value. When the air pressure is increased, the apertures at the bottom surface of the bottom chamber emit air, creating an air cushion underneath the air mattress that facilitates lateral movement of the mattress over a flat or irregular surface, such as from a hospital bed to a stretcher, or from a stretcher to an operating table.

    摘要: A mist generator improves sterility of blowers having controlled forced air for patient warmers and lifters. The mist generator has a main body including a top wall with an opening, that traverses into a chamber adapted to receive a disinfectant, side walls and a bottom wall. The main body further includes an inlet duct adapted for attachment to a first hose which, in turn, is adapted for attachment to an output opening of the blower for delivery into the chamber of forced air carrying misted disinfectant. The main body also includes an output duct adapted for attachment to a second hose which, in turn, is adapted for attachment to an inlet opening of the blower for delivery of disinfectant misted air through internal components of the blower. The mist generator improves sterility of the blower, thereby mitigating microbial contamination of patient warmers and lifters, and hospital environments.

    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.
