Abstract: A nebulizer has an aperture plate, a mounting, an actuator, and an aperture plate drive circuit (2-4). A controller measures an electrical drive parameter at each of a plurality of measuring points, each measuring point having a drive frequency; and based on the values of the parameter at the measuring points makes a determination of optimum drive frequency and also an end-of-dose prediction. The controller performs a short scan at regular sub-second intervals at which drive current is measured at two measuring points with different drive frequencies. According to drive parameter measurements at these points the controller determines if a full scan sweeping across a larger number of measuring points should be performed. The full scan provides the optimum drive frequency for the device and also an end of dose indication.

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 10 μm to 40 μm, and a width in the range of 20 μm to 150 μm, 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.

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 nebulizer comprises a controller linked at its output to a nebulizer head, and at its input to a USB cable and USB plug for connection to a host system. The link between the USB plug and the controller is a USB cable with power and data channels. The controller comprises a boost circuit, a microcontroller 11, and a drive circuit. The latter provides power and control signals via a cable and proprietary plug to the nebulizer head. These signals provide power and control for a vibrating membrane receiving a liquid to be aerosolized. The controller has a housing with LED status lamps, and an ON/OFF button. The controller can be controlled via a host, either locally or remotely.

Abstract: A supplemental oxygen delivery system is described in which Aerosol is delivered into a housing 10, 20, which sits in the circuit from the supplemental oxygen supply and optional humidifier. The supplemental oxygen passes through this chamber 10, 20 in which the aerosol is located, and collects the aerosol transporting it to a patient via a nasal cannula 3 or a face mask 4. An aerosol generator 9 is mounted to the housing 10, 20 and delivers aerosol into an oxygen stream 13 flowing between an inlet 14 and an outlet 15 of the housing 10. The housing 10 also has a removable plug 16 in the base 17 thereof for draining any liquid that accumulates in the housing 10. There is no disruption of oxygen delivery to patients using nasal cannulas who currently have to use a separate face-mask when receiving nebulized medication.

Abstract: A photo-resist (21) is applied in a pattern of vertical columns having the dimensions of holes or pores of the aperture plate to be produced. This mask pattern provides the apertures which define the aerosol particle size, having up to 2500 holes per square mm. There is electro-deposition of metal (22) into the spaces around the columns (21). There is further application of a second photo-resist mask (25) of much larger (wider and taller) columns, encompassing the area of a number of first columns (2)1. The hole diameter in the second plating layer is chosen according to a desired flow rate.
