Technical Field

[0001] This utility model relates to the field of elderly care equipment technology, and in particular to an elderly care bed. Background Technology

[0002] With the increasing number of disabled and semi-disabled elderly people, traditional beds can no longer meet their needs for safe getting up and down, in-bed activities, and long-term care, while also placing a huge burden on caregivers. Therefore, nursing beds that combine ergonomics, mechanical design, and electronic control technology have emerged. Their core technology has evolved from the initial hand-cranked drive to motor drive, enabling electric adjustment of basic postures such as backrest and leg raising.

[0003] Nursing beds can reduce the burden of care and maintain the health and dignity of users. However, when adjusting the backrest and leg bending in nursing beds on the market, the bed board structure can compress the user's abdomen. This not only poses a risk of physical injury but also contradicts the core concept of caring for users. Therefore, a nursing bed is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a nursing home bed that aims to improve the problem in the prior art where the bed board squeezes the user's abdomen and increases the risk of physical injury when the user raises their back and bends their legs.
