Abstract
A device for administering medicaments to patients comprises a housing containing a cylindrical chamber. A support is arranged inside the chamber to support a carrier, such as a blister pack. The blister pack has a plurality of containers or blisters arranged in a circle. When a blister pack is located on the support its blisters are located in holes in the support member. A plunger is arranged to enter the chamber through a hole to engage and open a blister registered with it. When the blister is opened, medicament can be withdrawn by a patient inhaling through a mouthpiece. An external member is provided to rotate the support member to register the blister with the plunger in turn. Air can conveniently enter the chamber through a hole in a cover which is removable to permit blister packs to be loaded into the chamber onto the support member.
