Description

Technical Field

[0001] The utility model relates to the technical field of medical care, and more specifically to a rotatable and adjustable nursing mattress. Background Art

[0002] As the aging population in China becomes increasingly serious, the demand for nursing bed products in China is also increasing, which has led to a spurt in the development of nursing bed products. Nursing beds are generally for patients who are immobile and bedridden for a long time. They need to get out of bed with the help of nursing staff every day to eat and do rehabilitation training. Simply using manpower to help patients get in and out of bed is not only a great burden for nursing staff, but may also cause bumps, strains and other artificial injuries to patients due to improper force.

[0003] The prior art closest to the present application is publication number: CN219721136U, a footboard lifting structure of a rotating mattress, disclosed to include: an upper frame 1 and a lower frame 18, the upper frame 1 includes a back frame 2, a seat frame 3, a thigh frame 4, and a calf frame 5, characterized in that: a calf lifting device 9 is provided below the calf frame 5, the calf lifting device 9 includes: a second motor 10 and a calf support rod 11, one end of the second motor 10 is connected to the seat frame 3, and the other end is connected to the calf support rod 11, one end of the calf support rod 11 is hingedly connected to the seat frame 3, and the other end is hingedly connected to one end of a support plate 15, the support plate 15 is fixedly connected to the calf frame 5, the second motor 10 drives the calf support rod 11, and the support plate 15 and the thigh frame 4 are linked to drive the horizontal lifting of the calf frame.

[0004] The nursing mattress uses a third motor to drive the rotating device to drive the upper frame to move forward and backward, and then through the pulling force of the connecting rod, the rotating device drives the upper frame to rotate, which requires linear motion and rotation. Therefore, the center of gravity of the nursing mattress is shifted, which reduces the smoothness of the mattress rotation, and is pushed forward by the second motor, driving the calf support rod, thigh frame and support plate to work together, thereby driving the calf frame to descend horizontally to provide the patient with the function of getting out of bed. However, in practice, when the foot lifting structure descends, the foot support point provided is parallel to the ground, which is prone to empty stepping, causing the patient to suffer secondary injury, and therefore cannot meet the requirements of safe and efficient use.

[0005] In view of this, the utility model provides a rotatable and adjustable nursing mattress which can be stably rotated and safely used. Utility Model Content
