PCT No. PCT/SE95/00087 Sec. 371 Date Sep. 11, 1996 Sec. 102(e) Date Sep. 11, 1996 PCT Filed Jan. 31, 1995 PCT Pub. No. WO95/25556 PCT Pub. Date Sep. 28, 1995The invention relates to a device for producing a fine inhomogeneous aerosol, comprising a liquid container (1) and a liquid-conducting pipe (2) whose outlet orifice (6) at one end is located in a first disc (5) and whose other end extends towards the container bottom, wherein the pipe-outlet orifice (6) is located in the first disc (5) in the proximity of and is directed at least generally at right angles to a second disc (4). The device includes a gas conduit (3) which terminates in the pipe (2) in the proximity of its outlet orifice (6) in the first disc (5). The conduit (3) leads to the pipe (2) and draws liquid through the pipe by suction and, in the proximity of the pipe orifice generates a first aerosol which is directed towards the second disc (4) and forms thereon a film which spreads radially across the second disc (4) and is therewith thinned out, this film shattering at the border edges of the second disc (4) into droplets which form in the gas a second inhomogeneous aerosol. The device is used for producing a fine inhomogeneous aerosol for medical treatment purposes. A helium-containing gas can be used as the propellant gas. |
