ULTRAVIOLATE LIGHT STERILIZATION APPARATUS

摘要

A sterilization apparatus for sterilizing air includes an outer housing having side walls extending between opposed bottom and top walls that, together, define an outer chamber. An inner housing is situated in the outer chamber and includes opposed top and bottom ends and having a wall structure that defines a sealed inner chamber extending therebetween. The wall structure includes at least one side wall that defines a transparent window. An inlet port is in communication with one end of the inner chamber and that directs unsterilized air into the inner chamber. An ultraviolet (“UV”) light source is positioned outwardly adjacent the window and configured to emit UV light through the window and into the inner chamber when energized so as to sterilize air in the inner chamber. An outlet port is in communication with another end of the inner chamber that directs sterilized air downstream from the inner chamber.

1. A sterilization apparatus for sterilizing air in connection with an anesthesia or ventilator device, comprising:
an inner housing having opposed top and bottom ends and having a wall structure that defines a sealed inner chamber extending between said top and bottom ends, said wall structure defining an inner chamber; wherein said wall structure includes a side wall that defines a window covered by a transparent panel; an inlet port in fluid communication with one end of said inner chamber and configured to direct unsterilized air into said inner chamber; an ultraviolet (“UV”) light source positioned outwardly adjacent said window and configured to emit UV light through said transparent panel and into said inner chamber when energized so as to sterilize air in said inner chamber; and an outlet port in fluid communication with another end of said inner chamber and configured to direct sterilized air downstream from said inner chamber; wherein:
said wall structure includes three side walls that each define a window being covered and sealed by a transparent panel, respectively, and includes a fourth side wall having an opaque construction;said UV light source includes three spaced apart UV light assemblies, each UV light assemblies being outwardly positioned adjacent said respective transparent panels and configured to emit UV light into said inner chamber via said respective transparent panels.
