Clip-on device aims to improve inhaler technique

Poor inhaler technique can lead to poor asthma control, with increased rates of exacerbation but a new device aims to help patients use their inhalers correctly.

Designed to be used with GSK Evohaler® devices – but other formats are in the pipeline – the Clip-Tone E is a small, ring-shaped device which clips to the top of the inhaler. When the patient inhales, as soon as the correct inhalation rate is achieved, an acoustic signal will sound, giving a cue to actuate the canister. The tone will continue as long as the correct, slow and deep inhalation is maintained.

The manufacturer Clement Clarke International says the device will not change medication delivery but simply provides audible feedback to the patient to help them master good technique.

The device will be available on NHS prescription, and an animation can be viewed at
