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 ?m to 40 ?m, and a width in the range of 20 ?m to 150 ?m, 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: 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: A fixture is provided for holding a hollow, cylindrical device from an inside surface that includes a plastic collar component and a main frame fixture insert molded into the plastic collar component. The fixture may include a cross-wire adapted to: loop over a section of the main frame fixture; traverse a space between the main frame fixture and the plastic collar component; and loop over a section of the plastic collar component. An apparatus is provided for holding a cylindrical device having an open interior and at least one open end. The apparatus includes an engagement arrangement including at least two activatable projections on a distal end and a base attached to a proximal end of the engagement arrangement. The projections move radially when activated.
