Background
With the aging process of the population becoming faster, more and more patients need to be bedridden for a long time for treatment or rehabilitation, and the demand of nursing beds is increasing. When a patient lies in the bed for a long time, the body part is pressed for a long time to cause the blood circulation to be blocked, and the pressed part of the patient body is easy to generate bedsore, thereby bringing more pain to the patient. Therefore, the nursing bed becomes an important nursing work for turning over the patient, and not only can effectively prevent the bedsore, but also can relieve the discomfort of the patient lying in bed for a long time. Turning over a patient is a very burdensome task for medical staff and the family members of the patient.
The nursing bed with the turning-over function is a good choice for nursing patients lying in bed for a long time, and can effectively reduce the nursing intensity of medical care personnel and family members of the patients and improve the rehabilitation conditions of the patients. At present, the types of turning-over nursing beds in the market are various, most of turning-over mechanisms of the turning-over nursing beds adopt a mode of one-half or one-third of different bed surface rotary motions to drive a human body to turn over laterally, the turning-over mode of the outside bed surface rotary motion mainly has the problem of unsatisfactory turning-over effect, patients mostly lie in the middle of the nursing bed, and the middle part bed surface does not move in the turning-over process, so that the problem of uncomfortable turning-over can exist, medical care personnel and family members of the patients are required to move the direction of the outward rotary bed surface of the patients to assist in turning over, and a good turning-over effect is not achieved in the actual use process. The turnover bed with one third bed surface also has a structural form that the middle bed surface is turned, but the rotation axis of the middle bed surface is positioned on the center line of the nursing bed, so that one side of the middle bed surface is lifted up and the other side of the middle bed surface is correspondingly lowered, after the nursing bed is turned over, a patient is clamped in a sunken V-shaped groove by the middle bed surface and the bed surface on the lower side, the inclined bed surface makes the patient have poor comfort after the patient is turned over, and the bed surface sinks to one side in the turning over process, so that the patient lacks of safety. And, many nursing beds often can with nursing bed lift the back of the body, bend the leg function and interfere because of the reasons such as the function design is complicated, mechanism occupation space is big that stands up, and a lot of nursing beds are sombrerous to have cancelled and have lifted the back of the body, bend the leg and nurse bed basis function, perhaps with the sacrifice angle of standing up and stand up the area as the cost, cause to stand up nursing bed and by the weakening greatly in the in-service use function, many functions are fallen for the gimmick of product propaganda, and are magnificent and unrealistic.
Based on the problems of the existing turning-over nursing bed, a multifunctional electric turning-over nursing bed with safer and more stable turning-over action and more comfortable and reliable turning-over effect is needed to be designed.
