Background

The nursing bed is a common nursing facility in a hospital or a family, and realizes various nursing functions such as back lifting, turning over, defecation treatment, transfusion and drug administration and the like through an electric mechanism. The patient using the nursing bed usually has lost or limited self-moving ability, for the patient with lost motion ability, the motion of the patient depends on the assistance of the nursing staff completely, but for the patient with limited self-moving ability, such as the patient with damaged knee joint or the old with poor physical condition, the patient can use most functions of the nursing bed by the manual controller, but for the motion with more perfect lower limb moving ability or larger physical consumption, such as the motion from lying posture to standing posture, the patient also needs a certain degree of assistance of the nursing staff. The nursing bed in the prior art can be conveniently realized by folding a bed plate for supporting the back and a shank plate for supporting the shank; secondly, the patient stands up from the nursing bed, usually, the patient stands up at one side of the nursing bed, and before standing, the patient needs to perform a preparation action of suspending the lower leg at one side of the nursing bed; finally, rising up, the feet of the patient touch the ground, the legs exert force, the angle between the shank and the thigh is changed from 90 degrees to 180 degrees, and the patient stands independently.

In order to solve the action of a patient from a sitting posture to a standing posture, application number 2018116534350 discloses an auxiliary standing nursing bed, which can enable a folded bed board to rotate 90 degrees relative to a bed body by arranging a rotating push rod between the bed body and the bed board, so that a shank of the patient rotates to the side surface of the nursing bed, and a shank board supporting the shank of the patient is in a horizontal state perpendicular to the horizontal state. However, no relevant assistance is given to the patient's rising movement.

In the rising process of a patient, particularly in the process from 90 degrees to 120 degrees between a shank and a thigh, quadriceps femoris muscles are stressed most and act most difficultly, and the process is most painful for a patient with knee joint degenerative disease, so that upper body borrowing force is often needed to reduce the load of legs, and when the angle is more than 120 degrees, the stress of thigh muscles is gradually reduced. In addition, the distance between the sole of the foot and the ground is required to be further adjusted, and when the preparation action is completed, the patient's foot is usually in a suspended state and does not contact the ground, and before the rising action, the upper body needs to be twisted to the bed side, and the leg needs to be further extended out of the bed side, so that the patient's foot contacts the ground, which is also difficult for the patient.

The multifunctional property of the nursing bed inevitably improves the complexity of the structure, and meanwhile, the nursing bed also ensures the stability of the structure, so that most nursing beds are large in volume and heavy in weight. Due to the complex structure and high technical requirements for installation, the nursing bed in the prior art is usually assembled into a complete nursing bed in a factory during manufacturing, and then transported and carried to a use place. Because the volume of nursing bed is great, and weight is heavier, it is very inconvenient to carry, especially when as the family expenses, because the structural attribute of house, its elevator, passageway and door frame size are comparatively limited, and the transport of nursing bed is very inconvenient.
