FIELD: technological processes.SUBSTANCE: apparatus for cold sanitizing of medical devices having one or more internal channels, comprises: a sanitizing chamber (2) means (3) for feeding one or more sanitizing fluids comprising a plurality of hydraulic circuits (4, 4, 4"), each of them contains a bleed pipeline (5, 5, 5"), which can be connected to the corresponding reservoir (S, S, S") with sanitizing liquid, and a plurality of feed pipelines (6, 6, 6", …), comprising the corresponding output (14, 14, 14") to the sanitizing chamber (2) for injecting fluids under pressure into the mentioned chamber means (7) for providing hydraulic connection of the feed pipelines (6, 6, 6", …) with corresponding internal channels of the device postioned in the chamber (2). The feed means (3) comprise a circuit (18) for liquid recirculation including a pre-mixing chamber (19). The feed means (3) also comprise a central collector (9) mounted between the bleed pipelines (5, 5, 5") and the feed pipelines (6, 6, 6", …) and containing the mixing chamber (10) inside. The mixing chamber (10) comprises at least one inlet (11) for bleed pipelines (5, 5, 5") and a plurality of outputs (12, 12, 12", …), a corresponding feed pipeline (6, 6, 6", …) is connected to each of them to ensure equal pressure (P) values at the corresponding outputs (14, 14, 14", …).EFFECT: invention provides a uniform flow of sanitizing liquid inside the channels of device subjected to processing.13 cl, 6 dwgИзобретение относится к санитарной обработке медицинских устройств многоразового использования.
