Aging is the result of social and economic development, the general improvement of people's living standards, improvement of medical and health conditions, and scientific and technological progress. As my country's population ages, the safety of the elderly's daily lives has received widespread attention. At present, the children of most families are busy working during the day, resulting in the neglect of care for the elderly living alone or empty nesters. At the same time, as age increases, many elderly people experience inconvenience in their legs and feet, and their ability to take care of themselves deteriorates. Due to the decline in physical functions of the elderly, many tasks that need to be handled independently will be more or less inconvenient and require the help of others or the assistance of equipment. In today's era of increasingly expensive human resources, the importance of auxiliary equipment is also gradually rise. The survey found that the elderly will encounter some expected but unresolved troubles during the excretion process. In particular, the knee joints of the elderly are prone to fatigue injuries. When sitting down and standing up when using the toilet, their own weight will be affected. The increased pressure on the knee joint causes a certain degree of difficulty; especially after squatting for a long time, it is easy to suffer from cerebral ischemia and fainting when standing up suddenly, and even secondary injuries are extremely easy to occur when falling to the ground. . Therefore, it is very necessary to design an auxiliary toilet that can facilitate the elderly to sit and rise when going to the toilet.

The functions of existing toilet assist products are mostly limited to assisting the elderly to get up, and cannot serve the entire process of the elderly from using the toilet to getting up and leaving the bathroom. The auxiliary functions are not perfect; the handrails are mostly fixed on the movable seat cover of the base, which is easy for people to grab. If you fall due to instability on the armrests of the chair, the auxiliary support will not be effective.
