Inhalation unit introducing medicinal substances into breathing air

摘要

The medical inhaling arrangement comprises a breathing tube and a syringe system. The syringe is used for injecting e.g. a medicine into the breathing tube. An oscillating quartz crystal acts on the needle of the syringe and forms a vapour. A drive, in the form of a pump, controls the syringe piston, allowing the droplet size and concentration to be controlled.
