USPTO Abstract
A needleless drug particle delivery device, of the kind in which firing of the drug particles is caused by a sudden gas flow, characterised in that the device comprises a container (14) of compressed gas and a mechanism for releasing the gas from the container to create the gas flow, the mechanism comprising a rupture element (20) for breaching the container and a manually manipulable actuator for moving the element and the container relatively to one another to provide an initial breach whereby the gas is released to act on a piston portion to provide a servo action which causes the rupture element and container to move further suddenly relatively to one another to complete the breaching of the container and establish a maximum gas flow from the container.
