The invention relates to a spray device having a spray nozzle unit and at least one further spray nozzle unit. Each spray nozzle unit has at least one spray nozzle body, wherein said at least one spray nozzle body comprises a chamber for receiving a pressurized fluid. Said chamber is bounded by a spray wall having at least one spray orifice that extends through said spray wall and opens to an external environment. Each of said at least one orifice in a spray wall has a substantially identical predetermined size lying in a predetermined range and releases a mono disperse spray jet of the pressurized fluid fed from the associated reservoir. Said range within said first spray nozzle unit differs from said range within said at least one further spray nozzle unit, particularly said ranges do not overlap.
A Spray device, comprising a first spray unit, said first spray unit comprising a spray nozzle unit in fluid communication with a first reservoir for holding a quantity of a fluid to be sprayed, wherein said first spray nozzle unit comprises a first spray nozzle body with a first spray wall that is provided with at least one first spray orifice extending through a thickness of said first spray wall, said at least one first spray orifice receiving, during operation, said first fluid under pressure from said first reservoir at an inlet side and releasing a spray jet of said fluid to an external environment at a spray side, and wherein each of said at least one orifice has a substantially identical predetermined size, lying in a predetermined range, and comprising at least one further spray unit, said further spray unit comprising a further spray nozzle unit in fluid communication with a further reservoir for holding a quantity of a further fluid to be sprayed, wherein said further spray nozzle unit comprises a further spray nozzle body with a further spray wall that is provided with at least one further spray orifice extending through a thickness of said further spray wall, said at least one further spray orifice receiving, during operation, said further fluid under pressure from said further reservoir at an inlet side and releasing a spray jet of said further fluid to an external environment at said spray side, wherein each of said at least one further orifice has a substantially identical further predetermined size, lying in a further predetermined range that differs from said first predetermined range of said at least one first orifice of said first nozzle body of said first spray unit, wherein said first range and said further range have substantially no overlap, wherein said first range is a range between 2 micron and 5 micron, and wherein said further range is a range beyond 5 micron, particularly said further range being in a range between 5 micron and 10 micron.
A Spray device comprising at least one spray nozzle unit having at least one spray nozzle body, wherein said at least one spray nozzle body comprises a chamber for receiving a pressurized fluid and said chamber is bounded by a spray wall having at least one nozzle orifice that extends through said spray wall and opens to an external environment, wherein each of said at least one orifice has a substantially identical predetermined size lying in a predetermined range, wherein said at least one nozzle orifice is configured and intended to release a spray jet of a spray to be generated by said spray nozzle unit, and wherein, during operation, said at least one nozzle body of said spray unit is fed with said pressurized fluid from a reservoir containing a quantity of said fluid, wherein said spray device comprises at least one further spray nozzle unit having at least one further spray nozzle body, wherein said at least one further spray nozzle body comprises a chamber for receiving a further pressurized fluid and said chamber is bounded by a further spray wall having at least one further nozzle orifice that extends through said of said spray wall and opens to an external environment, wherein each of said at least one further orifice has a substantially identical further predetermined size lying in a further predetermined range, wherein said at least one nozzle further orifice is configured and intended to release a spray jet of a further spray to be generated by said further spray nozzle unit, wherein, during operation, said at least one further nozzle body of said further spray unit is fed with said further pressurized fluid from a further reservoir containing a quantity of said further fluid, and wherein said predetermined range of said predetermined size of said at least one orifice differs from said further predetermined range of said further predetermined size of said at least one further orifice, wherein said first range and said further range have substantially no overlap, wherein said first range is a range between 2 micron and 5 micron, and wherein said further range is a range beyond 5 micron, particularly said further range being in a range between 5 micron and 10 micron.
14-15. (canceled)
The Spray device according to claim 15, wherein said first reservoir is at least partly filled with said first fluid, said first fluid containing a corticosteroid as an active compound, and in that wherein said second reservoir is at least partly filled with said second fluid, said second fluid containing a bronchial dilatation agent.
