Abstract

See full text

The invention concerns an ultrasonic atomizer (10), which is intended for an inhalation treatment apparatus for persons suffering from respiratory diseases. The ultrasonic atomizer (10) comprises an atomizer device (11) provided with a drug container (12) as well as an ultrasonic oscillator (13) connected to the container (12), the oscillator preferably comprising an oscillating crystal. The atomizer device (11) is provided with a duct passing into the patient, advantageously a mouth piece and an air-inlet duct (15). The atomizer device (11) comprises a pressure detector (36) directly connected to it or a duct (16) that is connected to the atomizer device (11) and passes to the pressure detector (36) and transmits the pressure of the breathing air. The pressure detector (36) detects the changes in pressure resulting from inhalation or exhalation of the patient, whereby, starting from the beginning of the inhalation stage, atomizing can be switched on by the apparatus. The ultrasonic atomizer (10) comprises a regulating device (18) connected to the atomizer (11), by means of which regulator the operation of the ultrasonic oscillator (13) is regulated. The regulating device (18) and the atomizing device (11) are interconnected by means of an electrical connection (17), whereby, through this connection (17), an electrical oscillation can be supplied to the crystal present in the ultrasonic oscillator. The electric oscillation can be coverted to mechanical oscillation of the crystal. The apparatus comprises circuitry for switching on of the ultrasonic oscillator (13) at least when the inhalation stage of the patient begins. Also, a timing device (44) is provided, by which the duration of operation of the ultrasonic oscillator (13) can be regulated as desired.
