    摘要： The invention provides methods and apparatus for nebulizing liquids. In one exemplary embodiment, an apparatus is provided which comprises a thin shell member having a front surface, a rear surface, and a plurality of apertures extending therebetween. The apertures are tapered to narrow from the rear surface to the front surface. A liquid supplier is further provided which delivers a predetermined unit volume of liquid to the rear surface. A vibrator vibrates the thin shell member to eject liquid droplets from the front surface of the thin shell member.

    摘要： An inhaler that uses capillary effects to output droplets of pharmaceutical product is described. The inhaler includes transducers and lenses to generate focused acoustic waves. The frequency and pulse width output of the transducers are set to cause capillary action in a reservoir of pharmaceutical product. The capillary action results in the ejection of small droplets of pharmaceutical product at low frequencies.

    摘要： An aerosolization device comprises a housing having a mouthpiece, an aerosol generator, a flow sensor and a controller. The controller is configured to begin operation of the aerosol generator upon receipt of a signal from the flow sensor indicating that a threshold flow rate has been achieved by a user when inhaling a tidal breath through the mouthpiece, and to stop operation after the passage of an operation time period that is selected such that continuation of the tidal breath delivers substantially all of the aerosol to the lungs.

    摘要： An improved method and apparatus for delivering medication to the lungs is described. Acoustic ink printing technology is modified to operate as an inhaler that generates tiny droplets near a patient's nose or mouth. The tiny droplets are easily carried by air currents into the patient's lungs. The inhaler itself is preferably a battery operated portable device that can be easily carried and easily cleaned to avoid contaminating the medication.

    摘要： A device for nebulizing a fluid is supplied which has a flow director. The flow director helps to direct any bubbles formed by the nebulizing device away from the nebulizing device. The nebulizing device has a vibrating element with apertures through which the fluid is dispensed. A dispensing chamber is defined between the flow director and the vibrating element. The dispensing chamber has an inlet which is positioned below an outlet so that bubbles naturally migrate up and away from the vibrating element.

    摘要： A hand-held compressor nebulizer suitable for vaporizing liquid medication, comprising a casing (2) and a motor-driven air pump (5). The nebulizer includes a liquid medication supply unit and a vaporizing unit. The vaporizing unit comprises upper and lower vaporizing chamber (9 and 6), said lower chamber (6) including a reservoir (12) for liquid medication from the liquid medication supply unit. The vaporizing unit includes a hollow conical member located within lower chamber (6) and defining an internal conical passage (11) having a relatively smaller upper end and a relatively larger lower end, said lower end being in communication with the air pump (5) for receiving an upward airflow produced by the air pump (5). The airflow increases in speed in the upward direction and creates a negative pressure upon exit from the upper end of the conical passage (11). The vaporizing unit further includes a vaporizing jacket (7) having a tapered interior and disposed around the conical member to form a narrow gap with the conical member. The gap has an upper end in the vicinity of the upper end of the conical passage (11) and a lower end in communication with the reservoir (12), such that said negative pressure can cause, by way of suction, liquid medication in the reservoir (12) to move upwards along the gap and subsequently be vaporized by the airflow upon exit from the upper end of the gap.
