A vibrating mesh nebuliser. The nebuliser (100, 400, 500) comprises a cartridge section (110, 420, 520) comprising a reservoir (180) containing a liquid to be nebulised (190), a mouthpiece comprising a conduit (160), wherein a flow path (210) is defined between the reservoir (180) and the conduit (160) and whereby a user may inhale nebulised liquid from the mouthpiece through the conduit (160). The nebuliser further comprises a body section (120, 410, 510), releasably connectable to the cartridge section (110, 420, 520) and a mesh section (530) comprising a vibratable mesh (250, 540), the vibratable mesh (250, 540) being disposable in the flow path (210), so as to nebulise liquid drawn from the reservoir to the conduit in the mouthpiece. Also provided are an apparatus and method for monitoring one or more physiological responses to material self-administered by a user.

Novel nebulizers and methods are provided for a nebulizer including a dialable negative pressure threshold valve that actuates in response to different negative pressures corresponding to different negative pressure threshold settings of actuation of the valve to influence inhalation effort, aerosol entrainment, and aerosol delivery.

A humidifier includes a second housing. A water storage tank is in a housing space of the second housing. The tank is detachable through an attachment/detachment port of the second housing. A third introduction hole communicates an inside and an outside of the second housing with each other in the second housing. A first tank hole communicates an inside and an outside of the tank with each other in the tank. Between the second housing and the tank, a first seal member separates a first downstream side flow path leading to an inside of the tank through the third introduction hole and the first tank hole, from an external space of the second housing. The first seal member extends along an inner surface of the second housing to entirely surround the tank, when viewed from a top of the tank.

A mesh type atomizer according to an embodiment includes a porous thin film having a multi-hole structure, a metal layer covering a remaining area except a nozzle area in which droplets are sprayed through the holes on a surface of the porous thin film, and an ultrasonic transducer to output ultrasonic waves to vibrate the porous thin film. According to an embodiment, it is possible to atomize a liquid into nanometer-level fine particles using the porous thin film including nanometer sized holes. It is possible to precisely adjust the sprayed droplet size by setting the shape, size and cycle of the nozzle in the manufacturing process, and it is possible to selectively increase the strength of the mesh by growing the metal material in the hole of the porous thin film through electroplating.

A surface acoustic wave (SAW) atomizer system for use in providing a nebulized medicament to a patient is described. The system may include a SAW atomization engine with an atomization region on a substrate that is separated from the interdigitated transducers (IDTs) on the substrate by a fluid barrier that seals off liquid fed into the atomization region from the adjacent IDTs and electrical contacts driving the IDTs.

A method of regulating pain in a patient includes operations of measuring a patient pain level, determining a dose of ethanol which does not trigger alcohol intolerance or intoxication, delivering the dose of ethanol to the patient by inhalation from an active mesh nebulizer at a repeated interval, measuring the pain level of the patient at a monitoring interval, and determining, based on the patient pain level, whether to adjust the ethanol dose. The dose of ethanol is delivered in the form of particles of nebulized liquid having a diameter ranging from about 0.5 μm to about 5.0 μm, which are rapidly absorbed into the bloodstream of a patient and delivered to the brain.

The present invention includes and provides a method of delivering a medicament to an eye of a subject in need thereof a solution, the method comprising: (a) providing droplets containing the medicament with a specified average size and average initial ejecting velocity; and (b) delivering the medicament to the eye, where the droplets deliver a percentage of the ejected mass of the droplets to the eye.

The present invention relates to a membrane unit for generating an aerosol in an aerosol therapy device, the membrane unit comprising a membrane (1) having an area (6) comprising a plurality of through-holes for nebulizing a fluid and a flange (7) circumferentially surrounding the area (6), and a substrate (2) having an opening (8) wherein the flange (7) of the membrane (1) is welded to the substrate (2) so that the area (6) is located in the opening (8) wherein the weld (5) comprises at least three discontinuous welds (5c) arranged at a distance from each other a long a circumference of the opening (8) and a first annular weld (5b) circumferentially surrounding the opening (8).

An ultrasonic droplet delivery device and related methods for delivering precise and repeatable amounts of a substance to a user for respiratory use is disclosed. The ultrasonic droplet delivery device generally comprises a body housing, a mouthpiece having an ejector mechanism, and a fluid cartridge having at least one fluid reservoir. In certain embodiments, the ejector mechanism may comprise at least one ultrasonic actuator and at least one aperture plate with a plurality of openings formed through its thickness for ejecting droplets. The device may further comprise at least one differential pressure sensor configured to activate the ejector mechanism upon sensing a pre-determined pressure change within the device to thereby generate the ejected stream of droplets.
