Abstract:
A device for inhaling pharmaceutical drugs by means of auxiliary positive-pressure respiration, comprising:a mouthpiece; a reservoir having a variable volume to accommodate inhalant gas and connected to the mouthpiece; an adjustable, airtight closure between the mouthpiece and the reservoir and at least one connection for feeding a pharmaceutical drug to the reservoir, said reservoir having a variable wall to change its volume which can be extended by inflowing pressurized inhalant gas acting against a restoring force, with the result that there is positive-pressure assistance when the inhalant gas containing the pharmaceutical drug is inhaled because of the action of the restoring force, the reservoir having at least one rigid wall section, to which at least one of a distributor, a connection for the mouthpiece, an inhalant gas filler connection and the pharmaceutical drug feed is attached, the reservoir having at least two wall elements which can move over each other, can be displaced relative to each other to increase the volume and are elastically pre-tensioned against a sliding motion to increase the volume by a spring device.
