This project is designed to address oxygen-related needs in home healthcare, elderly care, post-surgery recovery, high-altitude travel, and daily health management, with the goal of developing Haier’s line of medical-grade home oxygen concentrators. Utilizing molecular sieve oxygen generation technology, the product separates, concentrates, and delivers oxygen from the air in a stable manner, providing users who require oxygen therapy with a more convenient, safe, and reliable home oxygen solution. The product integrates oxygen generation, nebulization, smart display, timer control, and voice prompts, balancing the practicality of home care with ease of use for the elderly. Its design features rounded edges, a large interactive screen, a top-mounted control panel, and status indicators, minimizing the cold, clinical feel of traditional medical equipment and allowing it to blend more naturally into the home environment.
