Nulcer: A Wearable for Preventing Pressure Ulcers

Pressure Ulcers (or bed sores) are a common medical problem associated with people with low mobility in a wide range of clinical settings. This includes wheel chaired people, bedridden patients in hospitals who are in coma, in rehabilitation or who have undergone a surgery. In the United States, almost 2.5 million patients develop pressure ulcers each year and the treatment cost can reach as high as $20,000 for a single patient. Almost 50,000 people die every year due to complications related to pressure ulcers. In Pakistan, hundreds of people are confined to wheel chairs who are then at risk of developing pressure ulcers. Present methods for it’s prevention include air mattresses and skin care remedies which have proven to be ineffective and costly.


Nulcer is a wearable garment (shorts) that uses Electrical Stimulation (ES) to prevent pressure ulcers. ES has been proven to be effective in preventing pressure ulcers by aiding the body’s nutrients and blood flow in a muscle under pressure. The garment includes electrodes to provide ES to the gluteal muscles, since these are the most affected by pressure ulcers. The ES device mounted on the front of the garment is wirelessly controlled via Bluetooth Low Energy from a mobile app. The app offers pre-configured therapy regimes as well as option to select customized settings, includes data analytics stored on a cloud and connects the patient and doctor for therapy analysis and effectiveness.
