[On experiences with the new ultrasonic inhalation generator TuR USI 50 (author's transl)].

The paper deals with our experiences with the new TuR ultrasonic nebulizer USI 50, whose nebulizer chamber consists of glass and stainless steel. It works with an electronic feed system and has an electronically controlled heater for the production of thermoaerosols. In an alternating series of nearly 1,000 inhalations with normal and thermoaerosol, about 3/4 of the patients preferred thermoaerosol, about 20% preferred normal aerosol while 10% did not find any difference. According to our experiences the TuR USI 50 can be recommended for medical application.
