Multifunctional intelligent auxiliary turn-over sickbed

Technical Field

The invention relates to the field of medical care, in particular to a multifunctional intelligent turn-over assisting sickbed.

Background

For some patients and old people who need to lie in bed due to movement inconvenience, the simple actions of sitting, half lying and side turning are difficult to be completed by themselves, and the situations of unsmooth blood circulation, tissue edema, bedsore and the like can be caused by long-term lying. The intelligent electric sickbed aims to reduce the occurrence of the condition, so that a patient can independently adjust the prone position and turn over when being awake. Therefore, the pain of the old and the patient can be relieved, the labor amount of nursing personnel can be reduced, the labor intensity is reduced, and the utilization efficiency of the nursing personnel in the hospital is maximized.

At present, the domestic auxiliary side-turning sickbed only consists of two sections of transverse plates, can only realize the side turning of a single plate, and has insufficient safety stability and flexibility. And various domestic sickbed main bodies still drive the sickbed through the hand-cranking movement of people. However, under normal conditions, the lying positions of the patients are not fixed, and when the patients are in certain lying positions, only two turnover plates of the existing sickbed can not ensure that the patients can be assisted to complete safe and effective turnover actions. In addition, the completion of the actions can be completed under the condition of assistance of other people, and when no person attends, the patient still cannot independently complete the actions of sitting, side turning and the like.
