Abstract: An aerosol generator (100) has a vibratable plate (1) with apertures therein and an annular piezo (2) which causes movement of the vibratable plate (1). An annular support member (3) supports the piezo (2) and the vibratable plate (1). A first electrical power conducting pin (10) engages directly with a first, top, surface of the piezo (2). A second electrical power conducting pin (11) indirectly conducts electrical power to a second surface of the piezo (2), by contacting an extension tab (103) of the support member (20), also on its top side. There is a film of cured epoxy adhesive on the tab (103), providing excellent gripping force between the pin (11) and the support (3). The aerosol generator (100) avoids need for soldered joints for electrical contact, and the pins are conveniently mounted parallel to each on the on the same lateral and top side of the piezo and support member. The pins may have multi-point tips (50) for particularly effective electrical contact.

Abstract: An aperture plate is manufactured by plating metal around a mask of resist columns having a desired size, pitch, and profile, which yields a wafer about 60 μm thickness. This is approximately the full desired target aperture plate thickness. The plating is continued so that the metal overlies the top surfaces of the columns until the desired apertures are achieved. This needs only one masking/plating cycle to achieve the desired plate thickness. Also, the plate has passageways formed beneath the apertures, formed as an integral part of the method, by mask material removal. These are suitable for entrainment of aerosolized droplets exiting the apertures.

Abstract: A system for delivery of aerosol therapy to spontaneously breathing patients comprises a housing which defines a chamber. The housing has a base, a top and a main body extending between the base and the top. An ambient air inlet is located adjacent to the base and is normally closed by an inlet valve. The housing also has a patient port for receiving a mouthpiece or a face mask. The mouthpiece has an exhaust outlet closed by an exhaust valve. Similarly, the face mask has an exhaust outlet closed by an exhaust valve. Exhaled air is exhausted through the valves and to prevent recirculation through the chamber which would adversely affect dose efficiencies. The housing also has an aerosol port for receiving a vibrating mesh aerosol generating device. The aerosol port is located in a side of the main body of the housing for delivery of aerosol into the chamber between the inlet valve and the patient port. A boss extends upwardly from the base and is spaced-apart inwardly of the main body of the housing to define a reception space or well.

Abstract: A method for aerosolising a liquid comprises the steps of:—providing an aperture plate having at least 100 outlet holes per mm2; delivering liquid to the aperture plate; and vibrating the aperture plate to produce an aerosol. The viscosity of the liquid is in the range of from 1 to 15 cP and the surface tension of the liquid is in the range of from 72 to 0.5 mN/m. The output rate of the generated aerosol is greater than 0.01 mL/min.

Abstract: An aerosol delivery system has a nebulizer and a humidifier providing a gas flow to the nebulizer. A controller varies humidity level of the gas flow to the nebulizer so that if the nebulizer is not operating it has about 100% humidity and it is operating the value is less to allow for the humidification effect of the nebulizer. The control may be achieved by dynamically varying proportions of flow through a dry branch and a humidification branch.

Abstract: A liquid reservoir (100) of a nebulizer has a funnel portion (102) with ribs (103, 104) extending downwardly along a side wall towards a reservoir outlet (105). The ribs (103, 104) prevent the formation of air bubbles between the aperture plate and medication as any trapped air will be expelled along the geometry formed by the rib or groove and reservoir wall. Bubble formation is therefore prevented with only modification of the wall internal surface configuration of the reservoir.
Abstract translation: 喷雾器的液体储存器（100）具有漏斗部分（102），肋部（103,104）沿着侧壁朝着储存器出口（105）向下延伸。 肋（103,104）防止在孔板和药物之间形成气泡，因为任何被捕获的空气将沿着由肋或槽和储存器壁形成的几何形状排出。 因此，仅通过改变储存器的壁内表面结构来防止气泡形成。

Abstract: A method for manufacturing an aperture plate includes depositing a releasable seed layer above a substrate, applying a first patterned photolithography mask above the releasable seed layer, the first patterned photolithography mask having a negative pattern to a desired aperture pattern, electroplating a first material above the exposed portions of the releasable seed layer and defined by the first mask, applying a second photolithography mask above the first material, the second photolithography mask having a negative pattern to a first cavity, electroplating a second material above the exposed portions of the first material and defined by the second mask, removing both masks, and etching the releasable seed layer to release the first material and the second material. The first and second material form an aperture plate for use in aerosolizing a liquid. Other aperture plates and methods of producing aperture plates are described.

Abstract: An aperture plate (1) is attached at its rim (203) to a support washer (3) by adhesive. Anchor grooves (204) having a zig-zag pattern in plan are machined in the lower surface of the rim (203 of the aperture plate before application of the adhesive. The grooves (204) extend out to the edge of the aperture plate (1). The anchor grooves have a depth in the range of 10µm to 40µm, and a width in the range of 20µm to 150µm, and an angular pitch in the range of 2.5° to 12.5°. Excellent bonding strength is achieved for long term reliable attachment in an environment of high frequency vibration and moisture and chemical corrosion.
