Description

Technical Field

[0001] The invention relates to a household elderly assistance device, in particular to an elderly toilet assistance device suitable for the elderly's daily life and matching with a squat toilet. Background Art

[0002] As the problem of population aging in my country continues to intensify, the social and family structures have also been greatly affected. The pressure faced by the elderly in terms of pain care and elderly care has continued to increase. These have a direct impact on the family life and social stability of urban and rural residents, and have received widespread attention and high attention. How to solve basic life problems such as physical weakness and difficulty in self-care for the elderly, and how to improve the quality of life and personal safety of the elderly have become one of the urgent problems to be solved by the whole society and every family.

[0003] In daily life, difficulty in using the toilet is one of the most common problems for the elderly. Every year, there are frequent incidents of falls and injuries while using the toilet due to the decline in the elderly's physical functions, causing harm to the elderly and their families. It is urgent to develop elderly-assisting appliances and devices suitable for the elderly and frail people who have difficulty taking care of themselves, so as to improve and ensure the quality of life of the elderly.

[0004] At present, toilet facilities are basically divided into two categories: squat toilets and toilets. Most public toilets and household toilets in my country are equipped with various types of squat toilets, involving most people and families in urban and rural areas and rural areas. There are basically two types of toilet-assisting devices for the elderly on the market. One is that squat toilets are equipped with support armrests or simple toilet chairs. Although the structure is simple and the price is cheap, there are problems such as poor power-assisting effect, poor safety, and difficulty in ensuring cleanliness. The other is hydraulic power-assisting intelligent toilet equipment, such as electric lifting toilet chairs, etc. This type of product is basically used with toilets. Due to its complex structure, cumbersome operation, and high purchase and use costs, it is difficult to promote its use in ordinary families and public places. The existing toilet-assisting appliances and equipment for the elderly are far from meeting the needs of the elderly, and cannot fundamentally solve their problems of weakness and difficulty in moving. The development of products to help the elderly has received widespread attention from the country and society.

[0005] As the aging problem in my country becomes increasingly prominent, the development of elderly-assisting products has received more and more attention. The existing toilet-assisting devices for the elderly on the market have been studied and analyzed. They should not only help the elderly to use the toilet independently, ensure comfort and safety, but also be economical, practical and easy to promote in ordinary families. The toilet-assisting device for the elderly matching squat toilets of the present invention can not only realize the function of converting the squat toilet position into a sitting toilet position, but also solve the problem of helping the elderly to sit up when using the toilet. It has the characteristics of stable assistance, simple operation, safety and reliability, cleanliness and hygiene, and low manufacturing and maintenance costs. It can meet the modification needs of old urban communities, nursing homes and public toilets. This technology has not been applied in toilet-assisting devices at home and abroad, and can solve the needs of the elderly and the weak and powerless to help with toileting. It has important practical significance and good application prospects for promoting the promotion, application and development of my country's elderly-assisting devices. Summary of the invention
