Abstract
An ultrasonic dosage device having an enclosure for providing a medication in the form of a nebulized mist, including an energy source positioned within the enclosure and a vibration device with a switch for applying electrical energy from the energy source to the vibration device. An assembly is attached to the enclosure and has a membrane disposed between the vibration device and the medication for containing the medication and maintaining the medication in contact with the vibration device only by way of the membrane, whereby the membrane is vibrated and the medication is thereby converted into the mist by vibrations transmitted to the medication by way of the membrane when power is applied to the vibration device.
