Abstract:
1. A device for the topical dispensing of a powder comprising: a powder receptacle storing the powder; a gasflow generator adapted, in use, to cause gas to flow through the device, the gasflow generator being external to the device and comprising a connector which is adapted to be coupled to the gasflow generator; an actuator; a trumpet valve; and an agitator configured to mechanically vibrate the powder receptacle to release powder from the powder receptacle, the gasflow generator, the actuator, the valve and the agitator being operably linked such that actuation of the actuator causes the valve to open, permitting gas to flow through the device, actuating the agitator to cause the receptacle to be mechanically vibrated to release the powder and to entrain the powder that has been released from the powder receptacle in the gas flow, thereby to dispense powder from the device, wherein the agitator is driven by the gasflow, such that the agitator operates for as long as the valve is open and the gas flows and is disengaged when the flow of gas is halted, and wherein the agitator includes a moveable agitator element that is positioned within a path of the gasflow, wherein the powder is a haemostatic composition and the device is configured to dispense powder through a gas flow outlet to internal tissues exposed during surgical procedures or after traumatic injury, the powder being dispensed from the powder receptacle until the actuator is selectively unactuated by a user.
