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: 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: 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 aerosolised. 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 high flow nasal therapy system (1) has a gas supply (2), a nebulizer (12), and a nasal interface (7). There are two branches (11, 10) and a valve (6) linked with the controller, the branches including a first branch (11) for delivery of aerosol and a second branch (10) for delivery of non-aerosolized gas. The controller controls delivery into the branches (11, 10), in which flow is unidirectional in the first and second branches, from the gas supply towards the nasal interface. The first branch (11) includes the nebulizer (12) and a line configured to store a bolus of aerosol during flow through the second branch (10). The valve (6) comprises a Y-junction between the gas inlet on one side and the branches on the other side.

Abstract: A gas therapy system (1) has a flow line (3, 2), a coupler (6) to a gas source, and an aerosol generator (4) for aerosol delivery, and a patient interface such as a nasal interface (2). A controller (10) is configured to modulate gas flow and aerosol delivery in real time. The controller changes gas flow rate and dynamically reduces aerosol delivery during upper gas flow rates such as 60 LPM, and activates aerosol delivery during lower gas flow rates of for example 10 LPM. The control may also include sensors to detect breathing, so that there is a bias towards increased aerosol delivery during inhalation in addition to during lower level gas flow.

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 aerosol delivery system has an aerosol generator with a vibrating aperture plate (10) and an actuator (11, 16, 17, 19), a controller (18, 19). The controller in real time monitors (201) the aerosol generator as it is driven for vibration of the aperture plate, and detects (202) a change in an electrical characteristic in response to a transition from a wet state to a dry state of the aperture plate. It automatically modifies (203, 205, 206), during the transition, operation of the aerosol generator in response to the detected change. The modification includes reducing applied power (203). The controller continues (204) to monitor during the transition, including monitoring the aperture plate for presence of residual liquid on the aperture plate first surface. The controller monitors at a number of drive frequencies and maintains data representing trends in a combination of the electrical characteristic signals at the different frequencies, and identifies a start of a transition if a calculated value rises above a threshold. There is one threshold for triggering a check scan for residual volume and a higher threshold to trigger an immediate shut down.
