Abstract
1478138 Inhalators BEECHAM GROUP Ltd 17 July 1974 [18 July 1973] 34273/73 Heading AST A device for the oral inhalation of powders e.g. for radiography, comprises a hollow elongate housing 1 with an outlet 2 at one end for application to a person's mouth, the other end communicating with a container 3 for powder which has one or more air inlet vents 11 adapted to direct incoming air into a turbulent stream within the container, the housing having air inlet vents 12 adapted to direct incoming air into a vortex within the housing, whereby the intake of breath by the user causes powder within the container to be fluidised, and to pass into the vortex of air in the housing and thence through the outlet to the mouth of the user, The air inlet vents 12 may be disposed at an angle of 10-80‹ to a radius of the housing and the air-inlet vents 11 may be disposed at an angle of 40-85‹ to the longitudinal axis of the housing, or alternatively the vents may be positioned adjacent internal angled barriers so that incoming air is directed to a circular path. Large particles are prevented from leaving the device by an extension 6 of the housing, projecting into the container, and inturned flange 13 at outlet 2. The outlet 2 may extend at right angles to the axis of the housing and may have a mouthpiece which is elliptical in section. The device may be separable into two parts by a screw thread 7 or snap-on joints.
