Research and development

inexo has been designed and manufactured by James Barr Design Ltd, a design consultancy based in Surrey (UK) with past experience developing disposable diagnostic and laboratory equipment.

A number of factors have been considered in the design of the product over and above the fundamental mechanics of use. Being easy to use and clean are of great importance with most adult users not requiring any supervision.

The product features a patent pending valve technology which governs airflow (and so resistance). This airflow management provides for a range of resistance settings 1-5. The computer simulations above graphically show the speed at which air can move throughout the device, noticeably faster for level 1 (right hand animation).

Materials and manufacture

The choice of materials for the inexo product were important as although the device is ‘non-invasive’ it needed to be safe, comfortable and pleasant for skin contact. TPE was identified as the the best material for the mouthpiece and valve with the added benefit of being dishwasher safe and recyclable. 

inexo is a Class I medical device (non-invasive, sterile etc). D
esigned to meet the standards set in MDD 93/42 EEC.

Easy to keep clean with normal 
dishwashing liquid and warm water (drip dry)

The moulded parts of inexo feature the SteriTouch additive – an antimicrobial additive which inhibits the growth of bacteria and mould.

Resistant to isopropyl alcohol, UV, and sterilising tablets.

No replaceable or consumable
parts (no ongoing costs).

inexo is manufactured in the UK.
