Auxiliary motion mechanical arm and nursing bed

Abstract

The invention discloses an auxiliary motion mechanical arm and a nursing bed and relates to nursing equipment. First rod pieces can be driven by external force to rotate around a first hinged joint. Athird rod piece can be driven by external force to rotate around a fifth hinged joint and change the included angle between a first rigid frame and the first rod pieces. A fourth rod piece can be driven by external force to rotate around a seventh hinged joint and change the included angle between a third rigid frame and the first rigid frame. The first rod pieces can rotate to simulate actions of the upper arm of a human body. The first rigid frame and the first rod pieces can simulate actions of the elbow of the human body by changing the included angle between the first rigid frame and thefirst rod pieces. The third rigid frame and the first rigid frame can simulate actions of the wrist of the human body by changing the included angle between the third rigid frame and the first rigidframe so that a supporting plate can provide dynamic supporting for a user, and the risk of sideslipping of the body of the user during side-turning can be reduced.

Description

technical field [0001] The invention relates to nursing equipment, in particular to an auxiliary motion mechanical arm and a nursing bed provided with the auxiliary motion mechanical arm. Background technique [0002] The user uses the nursing bed because he needs to rest in bed. In order to perform nursing work such as cleaning the body of the user, the nursing staff often needs to manually assist the user to roll over the body. However, due to the busy tasks of nursing work, there is often a shortage of manpower in reality. [0003] Nursing beds in the prior art have the function of assisting the user to roll over, but the auxiliary function is relatively weak. Generally, the user can only be assisted to roll over by flipping the mattress. In the process of flipping the mattress, the user's body is prone to slipping. The technical defect of the nursing bed in the prior art is that it lacks an auxiliary motion mechanism to prevent the user's body from slipping, which make...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide an auxiliary movement mechanical arm and a nursing bed, which can solve the technical problem that the side-turning nursing bed easily makes the user's body slide sideways through the mechanical arm, and can overcome the automatic movement mechanism of the existing manipulator. Major technical issues with high overall cost
