Especially for long-term bedridden patients, it can significantly improve blood circulation, prevent bedsores, and improve the quality of life of patients. With the intensification of social aging and technological advancement, massage air cushion has gradually become an indispensable auxiliary tool in families and medical institutions.
[0003] In the existing massage air cushion technology, the common design scheme mainly uses a single large-capacity airbag design, and the airbag is inflated and deflated by an air pump to achieve a massage effect. Although this method is simple and easy to implement, in actual applications, due to the uneven distribution of gas in the airbag, it is easy to cause excessive or insufficient pressure in certain parts, resulting in unsatisfactory massage effects. This uneven pressure distribution not only affects the user's comfort, but also reduces the effectiveness of massage, limiting the promotion and popularization of massage air cushions in clinical applications.
