摘要
A nebulizer apparatus to atomize liquid solutions or suspensions. The nebulizer is typically used in conjunction with a breathing circuit to deliver atomized medicine to a patient. A housing with an opening covered by a thin mesh plate is supplied with the liquid to be nebulized on an “on-demand” basis. The mesh plate or liquid is vibrated at ultrasonic frequencies to atomize the liquid as it passes through the plate into the breathing gases flowing through the breathing tube. The vibration is produced with a piezoelectric element. The most efficient point to produce vibrations is found by measuring current, voltage or phase angle taken by the piezoelectric element or by measuring the resistance of the strain gauge attached to vibrator.
