[Studies of microbiological contamination of ultrasonic apparatus used in pediatric aerosol therapy].

It was found that inflating tube is most rarely contaminated with microorganisms during the use of ultrasonic inhalator TUR USI 70. Glass cylinder is contaminated more frequently whereas a diaphragm, aerosol preparation, inhaling mask and a pipe joining it with the device are contaminated most frequently. Sporadic contamination of the inflating tube indicate an efficient work of air filters while frequent contamination of the diaphragm, aerosol preparation and glass cylinder prove that the contamination is caused by a coupling fluid. It was also found that ultrasound exerts a destructive effect on microorganisms in the aerosol preparation. The investigations have shown that the inhaling mask and tubes joining it with the device should be changed before each use while the other parts of an inhalator and aerosol preparation may be changed once per 15 inhalations. It was also noted that disinfection of different parts of the device by a 2% aqueous glutaric aldehyde (30 minutes at room temperature) is efficient in about 95%.
