Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a turning bed for paralyzed patients. Background Art

[0002] Paralyzed patients who are bedridden and unable to take care of themselves are prone to bedsores due to long-term bed rest, which is not conducive to recovery. Therefore, during the rehabilitation care process, patients often need their family members or medical staff to turn them over to avoid bedsores.

[0003] However, since the patient is paralyzed and cannot move, he can only rely on medical staff or accompanying personnel to turn the patient over, which is a large workload, and the patient needs to turn over frequently, which puts a great burden on the accompanying personnel. In order to solve the above problems, a Chinese utility model patent with authorization announcement number CN218129046U discloses a paralysis nursing bed, which is provided with a connecting belt, and a driving motor drives the connecting belt to rotate around the bed body. The patient lies on the bed body, and when the connecting belt moves, the connecting belt moves the patient on the bed body, and then the accompanying personnel fixes one side of the patient's body to drive the patient to turn over; however, when the connecting belt drives the patient to move on the bed body, the patient moves horizontally. If the patient needs to be turned over, the accompanying personnel still need to assist in turning the patient over, which is also very laborious, and if the movement speed of the connecting belt is too fast, the patient is also easy to fall off the bed and cause a fall injury.
