Peritoneal dialysis patients require multiple daily treatments and must carry substantial equipment, limiting their mobility and daily life. As a result, going out and maintaining social interactions becomes difficult. OSMO is a mobile vehicle that enables peritoneal dialysis treatment to be performed on board. It supports both CAPD and APD, allowing patients to choose the treatment mode based on their needs. By integrating medical functions into a mobile space, patients can complete treatment while traveling without carrying equipment, enhancing their mobility and quality of life.
