Description

Technical Field

[0001] The present invention relates to the technical field of medical beds, and in particular to a manual medical bed. Background Art

[0002] Manual medical beds are beds whose functions are adjusted manually, primarily used in medical, nursing, and rehabilitation settings. To meet the diverse needs of patient care, numerous improvements have been made to hospital beds, resulting in the diverse range of functions and types available today.

[0003] Currently, patients who are temporarily unable to move independently (such as those who have lost arm or leg motor function) require regular rehabilitation training. Systematic rehabilitation training (including passive training, assisted training, and nerve stimulation) is not only the basis for restoring function, but also a key measure to prevent muscle atrophy, maintain joint mobility, and avoid fatal complications. During the current rehabilitation training process, medical staff are usually required to systematically lift the arms or legs of patients who are unable to move independently and use external force to assist in recovery. This external force-assisted training can lay the foundation for their recovery, but frequent manual training can easily consume the energy of medical staff and increase their burden. Summary of the Invention
