Description

Technical Field

[0001] The invention belongs to the technical field of barrier-free equipment, and in particular relates to a wearable bathing chair. Background Art

[0002] As the elderly age or become affected by illness, their ability to take care of themselves in daily life gradually declines. For example, bathing is more troublesome for the elderly, especially for the elderly with poor independent mobility. Bathing is a very heavy task. Usually, they need the accompaniment and help of caregivers to complete the basic bathing process smoothly and safely. However, it consumes a lot of manpower and material resources, and cannot guarantee the privacy and safety of the elderly.

[0003] Currently, there are some elderly-assistant bathing devices on the market, such as bathing chairs, bathing beds, bathtubs, and fully automatic shower systems. However, these elderly-assistant bathing devices are still difficult for elderly people with limited mobility to use alone. In addition, existing elderly-assistant bathing devices usually have relatively simple functions, only providing a place for the elderly to sit or lie down when bathing, and cannot help the elderly wash their backs, etc. After bathing, they cannot assist the elderly to stand up from a sitting or lying position, which is still relatively inconvenient for elderly people with poor independent mobility. In addition, the structures of existing elderly-assistant bathing devices are relatively fixed and complex, with high manufacturing costs and low cost performance. Summary of the Invention
