The invention relates to medical engineering and can be used in devices for cleaning medical instruments presterilizing combined effect of the working solution and ultrasonic waves from biological, mechanical, medicinal and other contaminants. Reducing the cost of the device, simplifying its maintenance, increase operational reliability, the reduction apparatus nodes damage possibilities when loading medical instruments is achieved in that the device for presterilization ultrasonic cleaning medical instrument which comprises a housing with disposed therein ultrasound generator and the heating elements for heating washing liquid, washing liquid container with a lid, mounted in the housing, a metal mesh basket for posted eniya tool adapted to be mounted in the vessel for a fluid nozzle for cleaning internal cavities for medical instruments, two pumps, fluid circulation and drainage system, and the solution was set in a container, interactive programmable control panel disposed on the front wall of the housing, adapted to to control the ultrasonic treatment,-temperature water solution and set operations, and the hydrodynamic processing circulation system and liquid drainage, and a set of pa solution in a container formed by two pumps, one of which provides the circulation and drainage of fluid, and the other - a set of solution into the container and the nozzle for washing the cavities in the medical instruments are mounted on the side wall of the vessel and equipped with flexible hoses for connecting the cleaned medical instruments with internal cavities.Полезная модель относится к медицинской технике и может быть использована в устройствах для предстерилизационной очистки медицинских инструментов комбинированным воздействием рабочего раствора и ультразвуковых колебаний от биологических, механических, лекарственных и прочих загрязнений. Снижение себестоимости устройства, упрощение его обслуживания, повышение надежности в работе, снижение возможности повреждения узлов
