Embodiment Construction

[0019] Disclosed is an apparatus for aerosol substance delivery. In the illustrated embodiment, the device is configured for aerosol delivery of a drug, such as a respiratory drug, to the lungs. However, as noted further below, the features in the device (eg, flexible membranes, magnetic components, etc.) and their use are not intended to be limiting. Rather, it is contemplated that the features described herein may be used in other devices for the delivery of aerosol substances, including but not limited to: devices for vapor delivery (e.g., humidification devices), devices for Devices for wetting textiles (for example, irons), devices for cleaning, and other similar devices. The device is configured to deliver small liquid droplets (eg, water) carrying a drug or substance, and the device is formed from a combination of a vibrator and a flexible membrane. As noted above, the membrane is prone to degradation and difficult and cumbersome to clean. Therefore, separation of th...

Abstract

An apparatus (e.g., nebulizer) for aerosol delivery of a substance (e.g., a drug to a patient) has a mouthpiece (36); a chamber (34) holding a substance; a flexible membrane (38) having a plurality of apertures; and a vibrator (20) for vibrating the flexible membrane to form a flow of aerosol droplets of the substance that are ejected through the apertures and to the mouthpiece. The vibrator may be a piezoelectric element. A magnetic member (54) is provided on the flexible membrane and is configured to magnetically couple the flexible membrane to the vibrator. The magnetic member allows replacement of the membrane, without wasting the piezoelectric element.

Description

technical field [0001] The present invention generally relates to a device for delivering an aerosol liquid or substance. Background technique [0002] Devices for generating and delivering aerosolized liquids or substances are used in a variety of applications. For example, they can be used to deliver aerosol drugs, or can be used to generate vapor in other devices such as soldering irons. [0003] Medical devices for delivering drugs to patients in aerosol form have been in use since the mid-1950's. Such devices are used to deliver an inhaled pharmaceutical aerosol (IPA) to the lungs of a patient for the treatment of, for example, asthma, cystic fibrosis, and chronic obstructive pulmonary disease (COPD). Nebulizers are a class of devices used to deliver aerosolized medications. Nebulizers can use different types of mechanisms to aerosolize medication. Ultrasonic nebulizers use a power source to power a vibrating element that produces high frequency vibrations. These v...
