NOVELTY - The device (1) has a decontamination chamber (2), and a source (8) of biocidal fluid. A feeding unit (5) feeds fluid to chamber and a source of compressed air. The compressed air is defined as medical air. The source is a cylinder (7) of medical compressed air. The feeding unit comprises a nebulizer. A fan (15?) re-circulates air inside chamber in order to diffuse nebulized or gaseous biocide inside chamber. An expelling unit expels air from the decontamination chamber, and comprises activated carbon and HEPA filter (9).    USE - Device for sanitizing objects such as medical device in hospital, clinic, laboratory or other healthcare environment (all claimed).    ADVANTAGE - The device is made movable and stand-alone in simple manner. The device is moved to another hospital or laboratory once the sanitization/decontamination procedures in hospital or laboratory are finished. The cylinder of medical air and/or reconstituted air is used as source of compressed air, so that the sterile, dry air is used for washing the decontamination chamber by expelling air from the chamber through the filters and replacing air with medical air and/or reconstituted air. The presence of the cylinder allows for power saving while the air is already compressed. The need of compressor for filling decontamination chamber with the nebulized biocide is eliminated, and the need of vacuum pump during decontamination process is eliminated. The medical instruments containing sensitive components are safely decontaminated when the decontamination process is carried out at ambient pressure. The design of sanitizing device is simplified, by removing the security inputs/outputs and valves.    DETAILED DESCRIPTION - The fan is positioned adjacent to or in proximity of a filter, and one of expelling unit for expelling air and biocide from chamber is formed. An interception element intercepting an air flow is arranged between fan and filter. The interception element is movable in order to open or close the air passage through filter to the outside. A power source (10) is independent from the electric network, preferably hydrogen fuel cell unit, and/ or UPS and storage battery. UV-C lamps (4), a control unit (11) and programming units (12,13) are arranged. The programming units are selected from a display and a computer connected with control unit. The object in which a biocidal fluid is delivered into decontamination chamber is decontaminated. The decontamination chamber is washed. Medical air is delivered into the chamber and air is expelled through filter. The decontamination is carried out at ambient pressure and biocidal fluid is diffused into chamber by recirculating air by fans. The fan is used to expel air and biocidal fluid from chamber. The passage through filter is prevented during recirculating step by an interception unit which is closed during recirculating step and opened during washing step. The device is used in different healthcare environments and is transferred from one to another of environments. An INDEPENDENT CLAIM is included for process for sanitizing objects in hospital, clinic, laboratory or other healthcare environment.
