Description

Technical Field

[0001] This utility model relates to the field of rotary tilting beds, and more particularly to a rotary tilting bed. Background Technology

[0002] An existing patent (publication number: CN111568664B) proposes a three-fold nursing bed, including a lower bed frame and an upper bed frame. The upper bed frame includes a pair of three-fold linkage mechanisms, each comprising a rotating link and a balancing link arranged parallel to each other. Both ends of the rotating link and the balancing link are connected by a swing connector, which is rotatably connected to the ends of the rotating link and the balancing link. The lower bed frame has a pair of symmetrically arranged rotating supports, and the pair of three-fold linkage mechanisms are respectively connected to the corresponding rotating supports. However, in this device, "the lower bed frame has a pair of symmetrically arranged rotating supports, and the pair of three-fold linkage mechanisms are respectively connected to the corresponding rotating supports." The rotating supports are fixed to the lower bed frame, allowing the upper rotating links and other mechanisms to rotate only laterally, making it difficult to assist the patient in getting out of bed and affecting the convenience of patient use. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of existing technologies by providing a rotating side-turning bed that assists patients in getting out of bed.

[0012] 3. When assisting a patient to get out of bed, this utility model activates the electric cylinders for raising the patient's legs and lifting the legs, putting the patient in the raising and lifting position. By rotating the electric cylinders and the drive rack, the driven gear is controlled to rotate, thereby causing the side lower leg support frame, side thigh support frame, side seat plate frame, side back support frame, middle back support frame, middle seat plate frame, middle thigh support frame, and middle lower leg support frame to rotate 90° as a whole. The electric cylinder for lifting the legs retracts, and the side thigh support frame, middle thigh support frame, side lower leg support frame, and middle lower leg support frame descend in sections, bringing the patient's feet closer to the ground, facilitating subsequent assistance in getting out of bed.

[0013] 4. The side calf support frame and side thigh support frame of this utility model adopt a segmented design, so that the side thigh support frame can assist in supporting the thigh during the assisted ambulation process, and the side calf support frame can block the support of the calf during the assisted ambulation process, so as to ensure the comfort of the patient during the ambulation process.
