Abstract: An oscillatory respiratory therapy device 100 has an opening 8 to atmosphere through which air passes to the user. The device has a visual indicator 20 including a paper indicator 25 and a dye reservoir 29 mounted at the opening. Before use, the opening 8 is covered by a removable cover strip 21 that prevents air flowing through the opening. The cover strip 21 is attached to the dye reservoir 29 so that the reservoir is pulled against the paper indicator 25 when the cover strip is removed, thereby the device to be used. This causes dye to flow gradually from the reservoir 29 and spread outwardly across the paper indicator 25, which is marked to indicate duration of use.
