Abstract

A hand-held pharmaceutical dispenser (1) comprising first (10) and second (20) portions moveable relative to each other and defining an air chamber with rigid internal walls (26) therebetween. The second portion (20) has an annular seal (27) to seal against the first portion (10) to seal a volume of air in the air chamber (26). One of the first and second portions is arranged to support or include a container (14) for a medicament (15) to be dispensed. The first (10) and second (20) portions are arranged such that relative movement towards each other moves the first portion (10) relative to the annular seal (27) of the second portion (20) reducing the sealed internal volume of the air chamber (26) and compressing the air in the air chamber (26) until a shoulder (35) on the first portion encounters the annular seal (27) on the second portion opening a flow path for the compressed air in the air chamber (26) to be released with or after medicament (15) dispensed from the container (14). As the air chamber (26) has rigid internal walls and as the flow path for the pre-compressed air is opened at a predetermined point in the movement of the first (10) and second (20) portions towards each other at which the shoulder encounters the annular seal, the pre-compressed air is released at a predetermined pressure. This aids targeted medicament delivery. The dispenser (1) may have a seal (110) to, in use, act against the external surface of an orifice into which a nozzle (25) of the dispenser (1) is inserted.
