1. A device for cleaning and disinfecting medical and surgical instruments, comprising:
- a tubular body, one end of which is open and the other end of which is open for passage of fluid into a collection container for waste liquid, the body having an interior wall and a longitudinal axis,a plurality of nozzles fitted on the interior wall for supplying atomized disinfection liquid within the tubular body,each said nozzle having an injector in fluid communication with the nozzle for supplying disinfection liquid and pressurized air to the nozzle,means for supplying pressurized air to the injectors comprising an annular first duct extending through 360°
around the tubular body in a plane transverse to the longitudinal axis of the tubular body and means for providing fluid communication between the first duct and the injectors,means for supplying disinfection liquid to the injectors comprising an arcuate second duct extending 180°
about the tubular body in a plane transverse to the longitudinal axis of the body, a fluid inlet located centrally of the ends of said second duct, a third duct comprising two arcuate sections, each section extending 90°
about the longitudinal axis of the tubular body in a transverse plane spaced longitudinally from the plane of the second duct, means for providing fluid communication between each end of the second duct and a respective fluid inlet located centrally of the ends of each said section of the third duct; and
means for providing fluid communication between each end of the two arcuate sections of the third duct and an associated one of the injectors.

13. A device for cleaning and disinfecting medical and surgical instruments, comprising:
-
a tubular body with an elongate longitudinal axis, the body having one end open for the insertion of instruments and the other end open for passage of fluid into a collection container, the body having an interior wall; a plurality of nozzles on the interior wall for supplying atomized disinfection liquid within the tubular body; each nozzle having an injector in fluid communication with the nozzle for providing disinfection liquid and pressurized gas to the nozzle; supply means for supplying said disinfection liquid and pressurized gas to the injectors, comprising; first, second and third annular crowns disposed about the body transversely of the longitudinal axis, the first and second crowns abutting to form a first pair of crowns and the second and third crowns abutting to form a second pair of crowns; a pressurized air duct formed by one of the pairs of crowns, the crowns including inlet means for providing pressurized gas to the duct and means for providing fluid communication between the duct and the injectors; and first and second disinfection liquid ducts, the first disinfection liquid duct formed by the first pair of crowns and the second disinfection liquid duct formed by the second pair of crowns; a disinfection liquid inlet means in the first pair of crowns for supplying disinfection liquid to the first disinfection liquid duct;
means for providing fluid communication between the first disinfection liquid duct and the second disinfection liquid duct and means for providing fluid communication between the second disinfection liquid duct and the injectors. - View Dependent Claims (14)
