To both disrupt and dramatically improve the 'Cinderella' healthcare issue of venous leg ulceration. A global problem affecting some 300,000+  in the UK at any one time and >2 million in the USA. Estimates of costs to mange in the UK exceed £2Bn and in the US >$20Bn - both rising! Treatment, to get ulcers to heal, is universally accepted as graduated compression of the lower limb(s) affected, using either multi-layer bandages, or hosiery. The problem is that no one yet can accurately and repeatably apply compression even if very experienced. Our solution is unique - a disposable, sub-bandage pressure sensor(Graducheck) and mobile-based (App) display that allows the applier to 'get it right, accurately, first time and every time', with minimal training, enhancing healing rates that will clearly benefit patients, reduce healthcare costs and allow substantial profit. A second patent sits in the business for unique hosiery that will help stop ulcer recurrence and add to our overall value.
