Description
Technical Field
[0001] This utility model relates to the field of nursing beds, and in particular to an automatic defecation and turning bed. Background Technology
[0002] An existing patent (publication number: CN113171244B) proposes a nursing bed, including a bed frame and a bed board. The bed frame includes a bed base frame, an upper frame outer frame, an upper frame sliding frame, and a backrest and leg adjustment frame. The bed board includes a backrest, a seat, a leg board, and a lower leg board. The seat and the backrest and leg connection frame are bolted together. However, in this device, "the seat and the backrest and leg connection frame are bolted together, and the backrest and leg board are respectively hinged to the seat." The seat is a solid design, requiring the patient to get out of bed to defecate. This limits the ease of use for patients who have difficulty getting out of bed. Summary of the Invention
