Air decontamination devices

Abstract

Air decontamination method and device designed for bioterrorism, nerve gas, toxic mold, small pox, Ebola, anthrax and other agents require built in air sampling, rapid filter changes and the ability to use a mobile, transportable and connectable system in positive mode to push contaminates away or in negative mode to contain a toxin from spreading. This application combines features in respirators, industrial and hospital grade air filtration with the ability to provide air testing to guide the connection of the device with other treatment modules or existing HVAC and other equipment. With this new flexibility, ozone, UV, absorption, Thermal destruction, filters and liquid chemical neutralization can be manually or automatically adapted for emergency response to both daily airborne contamination and military grade terrorist threats of airborne contamination. The air decontamination units may be used to decontaminate the air after industrial and medical contaminations and terrorist biological, chemical and radiological attacks, for example. Mobile isolation units, and methods of decontaminating rooms, are disclosed, as well as Well as infection control and emergency response usage as an emergency clean air supply when connected to escape hoods, decon tents, or containment barriers to protect structures from homes to business from outside toxic agents. The unit can be powered by normal AC, 120 volts or 240 or be adapted to battery or field power supply units.

Description

technical field [0001] The invention relates to an air filtration unit and a mobile isolation unit including a purification unit. Background technique [0002] Purification units are typically designed to filter, irradiate and / or collect airborne irritants or infectious agents such as bacteria, viruses, mold and other microorganisms. Such irritants or infectious agents may contaminate the air, for example, due to industrial accidents, fires, infected individuals or chemical or biological terrorist attacks. Purification units typically include chambers for exposing contaminated air to ultraviolet (UV) rays followed by passage through filters. The filter may be a High Efficiency Particulate Acquisition (HEPA) filter. [0003] Ultraviolet rays in the prior art generally do not penetrate the filter sufficiently to kill the collected biological agents. Many biological substances, such as molds and bacteria, as well as collected viruses, can become sources of contamination or i...

Problems solved by technology

However, the mobile isolator draws large volumes of air into the unit, potentially causing further infection of the patient

These isolators can be dangerous for immunocompromised or respiratory compromised patients due to the potential for antibiotic resistant strains of bacteria and fungi to emerge in hospitals
