A surgical treatment system for contaminated air streams having particulate contamination, polar contamination and/or nonpolar contamination in the gas or vapor stream. A surgical smoke plume treatment system and method provide or define a multi-stage treatment process that mechanically filters the air stream, followed by nonpolar decontamination and then polar decontamination or treatment. The system may be used stand alone or incorporated and used with other surgical instruments or incorporated into an air handler adapted to decontaminate an air stream. A desiccant may optionally be used to remove water from the air stream.

The present invention relates to a novel isolating consulting table. The novel isolating consulting table includes a table body and an air outlet pipe, wherein an air inlet duct is inlaid on the table top; the air inlet duct and the air outlet pipe are located in the same vertical plane; an electric ion purification and disinfection system is arranged in the air inlet duct; the table body is provided with a pneumatic device; an air inlet and an air outlet of the pneumatic device are communicated with an air outlet of the air inlet duct and an air inlet duct of the air outlet pipe, respectively; the air outlet pipe includes a ventilation pipe, and an air outlet guide hood located at an air outlet of the ventilation pipe; an air outlet side of the air outlet guide hood is arranged toward the air inlet duct.

A nasal-plug filter device including a device body, a filter, a first actuator, a second actuator, and a gas sensor is provided. The device body has a ventilating channel, and the ventilating channel has an inlet end and an outlet end. The filter is disposed at the outlet end. The first actuator is disposed at the inlet end for being driven to transmit gas outside the device body into the device body. The second actuator is stacked on and bonded to the first actuator, and the second actuator is driven to transmit the gas transmitted by the first actuator to the filter to be filtered and purified. The gas sensor is disposed at the outlet end. A connection element may be provided for connecting two nasal-plug filter devices with each other.

A method for extracting and capturing airborne aerosol and particulate matters in the air that may be potentially contaminated with harmful bacteria and viruses using a vacuum extraction system; treating the contaminated air by scrubbing it with a biocide solution; filtering the scrubbed air using activated carbon and HEPA filters to remove any residual biocide; and optionally, treating the filtered air with UV-C, ozone, or plasma, before the sterilized air is return to the environment.

Devices, methods and techniques are disclosed to perform high confidence sterilization of indoor air with low power requirements. In one example aspect, a sterilization device includes a power source, an energy storage coupled to the power source and configured to store electric charges, a set of electrodes arranged in a specified geometry to have a fixed characteristic impedance, and a switch positioned between the energy storage and the set of electrodes. The switch is configured to operate to establish a pulsed electric field on the set of electrodes.

A device for reducing a carbon dioxide and water content in an enclosed air volume has first and second sorption units for sorbing carbon dioxide and water. The first and second sorption units can be transferred from a sorption mode into a desorption mode and vice versa. In the sorption mode, the first and second sorption units sorb carbon dioxide and water from raw air of the enclosed air volume. In the desorption mode, the first and second desorption units desorb carbon dioxide and water to supplied regeneration air. An air distribution device can switch the first and second sorption units, based on the carbon dioxide and water content, alternately from sorption mode into desorption mode such that, in at least one operating state of the device, one of the first and second sorption units is in sorption mode while the other is in desorption mode.
