A microstructured filter is presented having an inlet for unfiltered fluid; an outlet for filtered fluid; a plurality of projections, which form at least one row in a mutually juxtaposed relationship across the filter, that project out of a base plate and are an integral component of the base plate; a plurality of passages between the projections; and a cover plate which is securable to the base plate to cover the projections and the passages. The passages form a plurality of through paths from the inlet to the outlet. The inlet includes an elongate inlet slot for the unfiltered fluid that extends over approximately the entire filter width and is approximately as high as the projection on the outlet side of the filter.

Microstructured filter

A nozzle assembly for use in atomizing and generating sprays from a fluid. The nozzle assembly includes two members, each with generally planar surfaces, that are joined together. A first set of channels is formed in the generally planar surface of a first one of the members to form, in cooperation with the generally planar surface of the second of the members, a plurality of filter passageways. A plenum chamber is formed in the first member. The plenum chamber is in fluid communication with and downstream of the plurality of filter passageways. A second set of channels is formed in the generally planar surface of the first member to form, in cooperation with the generally planar surface of the second member, a plurality of nozzle outlet passageways. These nozzle outlet passageways are in fluid communication with the plenum chamber. The nozzle outlet passageways include a plurality of nozzle outlets which are adapted to discharge a plurality of fluid jets that impinge on one another to thereby atomize a flow of fluid.

A microstructured filter having an inlet for unfiltered fluid; an outlet for filtered fluid; a plurality of projections which are arranged in at least two rows in mutually juxtaposed relationship, project out of a base plate and are an integral component of the base plate; a plurality of passages between the projections and a cover plate which is securable to the base plate to cover the projections and the passages. The passages form a plurality of through paths from the inlet to the outlet. The inlet includes an elongate inlet slot for the unfiltered fluid that extends over approximately the entire filter width and is approximately as high as the projection on the outlet side of the filter.

A microstructured filter for a fluid, the filter having an inlet for unfiltered fluid and an outlet for filtered fluid, the filter comprising: a plurality of projections () which are arranged in at least two rows () in mutually juxtaposed relationship and which project out of a base plate () and which are an integral component of the base plate, a plurality of passages () between the projections (), and a cover plate which is securable to the base plate to cover the projections () and the passages (), wherein the passages form a plurality of through paths from the inlet to the outlet, said inlet comprises an elongate inlet slot () for the unfiltered fluid, which extends over approximately the entire filter width and which is approximately as high as the projection () projecting out of the base plate, on the outlet side of the filter. The filter according to the invention remains operational, even if a part of the filter area is obstructed. The filter is used for example in an atomizer with which an aerosol is produced from a fluid which contains a medicament.

Atomizing nozzle and filter and spray generating device

A nozzle assembly for use in atomizing and generating sprays from a fluid. The nozzle assembly includes two members joined together. In one of the two members are formed one or more nozzle outlets, one or more fluid inlets, and a plurality of channels that form filter passageways. The nozzle outlets discharge fluid jets that impinge on one another to thereby atomize the fluid. Alternatively, an impact element or a vortex-generating structure can be used in the nozzle outlet to atomize the fluid. Methods are also provided for producing the nozzle assembly by forming the inlets, outlets, and/or channels through electrical or chemical etching or other processes that selectively remove material from at least one face of a nozzle assembly member.
