A device for protecting against an airborne contamination of a medical device including an air circulation cooling system is disclosed. The device also includes an enclosure defining a sealed receiving volume for the medical device, the protection device further comprising structure for circulating gas flow, within the enclosure, the gas flow having predetermined composition and/or quality criteria different from the external environment and able to be used by the cooling system of the medical device in operation.

An air purification system includes a conduit extending between an inlet and an outlet, each in fluid communication with an enclosed environment. Ambient air from the enclosed environment enters the conduit via the inlet and treated air exits the conduit and enters the enclosed environment via the outlet. The system further includes a fibrous filter disposed within the conduit and configured to treat the ambient air thereby generating the treated air, and a renewal unit disposed within the conduit and configured to renew the fibrous filter.

An air sterilizing device has a casing, a wheel disc covered with microporous structures, a blower, and a sterilizing module. The casing has an air inlet and an air outlet. The blower located in the casing introduces the external air from the air inlet, and the external air is filtered and sterilized by the wheel disc and the sterilizing module. The filtered and sterilized air is discharged from the air outlet. The sterilizing module locates next to the wheel disc for sterilizing the air flowing through the sterilizing module and also for sterilizing the wheel disc by the relative rotation between the wheel disc and the sterilizing module. Bacteria and viruses attached to the wheel disc are eliminated, and the filtration and sterilization functions of the wheel disc are maintained. The efficacy and the efficiency of the air sterilizing device are therefore improved.

The formation of sterilization tubes by plates with parts that match in whole or in part, that when assembled together form ducts, passages, channels, or tubes in a mass or block of heat resistant material. The size of the block may be reduced by forming the ducts as curved passages or tubes that will keep or increase the length of the tube while keeping the same or more exposure time while the gas is passing through. If the length of the curved duct is the same as a straight tube would have been, the overall size of the assembly may be reduced from what it otherwise would have been. If the curved length is made longer while the size of the assembly is kept the same, the exposure time is increased for a more effective sterilization.

The air sterilization device with heating apparatus comprises a mainframe, a sterilization system, a heating system, circuits and a control system and a housing. The sterilization system includes an ultraviolet sterilization apparatus to sterilize and disinfect air; the heating system heats the air to inactivate virus; and the housing has an air inlet and an air outlet. Air can circulate into the housing through the air inlet with the action of mainframe and then the air is discharged from the air outlet into a room after the disinfection and sterilization processes are finished. The device with heating apparatus aims at the secondary inactivation of viruses by high temperature after the sterilization and disinfection processes are finished by ultraviolet sterilization apparatus and heating system, and at the decomposition of ozone produced in the process of ultraviolet disinfection to eliminate secondary air pollution by ozone.

An improved device for use in decreasing the transmission of viral and pathogenic materials by capturing the bodily fluids after a wearer sneezes. The device includes a housing having a bottom portion, a cover, and a base. The bottom portion having receiving members 28 for housing a filter and ventilation openings 32. The cover is removably secured to the first mid-section perimeter of the bottom portion and includes a pair of moveable doors that extend downwards when a nose guide 34 is engaged to receive the sneeze of a user.

A device for creating an air curtain protecting a human respiratory system is described. The device can be a hat and/or collar worn by a person and includes a constant or on demand flow of air that passes across a person's face to create an air curtain. The flow of air moving across the face blows airborne viruses away from a person's eyes, nose, and mouth. Another concept includes a glove that is outfitted with a device that purifies the glove. A battery could be mounted on a person's wrist or forearm with a small wire running down the glove. Likewise, the glove could be outfitted with UV light embedded on the surface or just underneath a permeable/top layer of the glove. Still further, the glove can carry electrical pulses aimed to kill viruses every ten seconds or so.
