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 formed from a palladium nickel alloy comprising about 89% palladium and about 11% nickel. There is a generally fine substantially equiaxed grain microstructure throughout the thickness of the aperture plate. The average grain width (W) is in the range of from 0.2 μm to 5.0 μm, in some cases from 0.2 μm to 2.0 μm. Because the grain structure is equiaxed (L/W=1) the grain length (L) is the same as the grain width. The improved aperture plate extends the life of nebulisers, eliminates the risk of premature and unpredictable failure of a nebuliser in service, eliminates the risk of product returns from hospitals and patients, and eliminates the possible risk of fragments of the aperture plate breaking free from the nebulizer.

Abstract translation: 孔板由包含约89％钯和约11％镍的钯镍合金形成。 在孔板的整个厚度上存在通常细的基本上等轴晶粒微观结构。 平均晶粒宽度（W）在0.2μm至5.0μm的范围内，在某些情况下为0.2μm至2.0μm。 由于晶粒结构为等轴（L / W = 1），晶粒长度（L）与晶粒宽度相同。 改进的孔板延长了喷雾器的使用寿命，消除了雾化器在使用中过早和不可预测的故障的风险，消除了医院和患者返回产品的风险，并消除了孔板破碎的可能性。 喷雾器。
