inexo® Inspiratory Muscle Training Device Launched by James Barr Design Ltd and Radical Materials Ltd

Globally recognised performance additive manufacturers RADICAL MATERIALS have collaborated with James Barr Design Ltd to launch the ‘inexo®’, an inspiratory muscle training (IMT) device that aids in the recovery and rehabilitation of respiratory conditions and potentially symptoms of long COVID. The patent-pending valve technology used in the inexo® allows the user to select five levels of breathing resistance as a way of exercising the respiratory system and to aid lung performance. The inexo® functions during both phases of the breathing cycle, but also allows the user to focus on just one direction of airflow. Overall, making the device a stellar alternative to other similar products on the market.

The importance of infection control, particularly in light of COVID-19 and the associated respiratory issues surrounding the intended users, led designer James Barr to incorporate industry-leading antimicrobial additive SteriTouch® into the TPE-based device. Consequently, inexo® devices protect the user against 99.99% of bacteria, including bacteria that can be particularly detrimental to respiratory conditions, such as: MRSA, Pseudomonas Aeruginosa and Streptococcus Pneumonia. The SteriTouch® additive achieves this by utilising silver ion-based technology to destabilise bacteria cell membranes, blocking the further replication of DNA.

Regarding his choice for using SteriTouch®, James Barr had this to say: “As the inexo® is a Class 1 medical device, using the SteriTouch® additive gives an extra level of protection to guard against infection.”
