Mechanism Design and Finite Element Analysis of a Bionic Anti-decubitus Multifunctional Medical Nursing Bed

Prevention of hemorrhoids is an important part of clinical nursing work. The main reason for this is that local tissues are under pressure for a long time, blood is not circulating for a long time, and oxygen deficiency leads to tissue ulceration and necrosis. Based on the characteristics of human activities and joint physiological data, this paper designed a bionic anti-decubitus multi-functional medical bed, which can realize push back, rollover, sitting posture and lift leg function, which can help patients complete these actions and reduce the care of the caregiver. Burden to improve patient comfort. The finite element analysis of the joint components was carried out in the paper. The results show that the design is reasonable and meets the requirements of patients with weight of 150Kg.
