Multifunctional nursing bed based on angle control

Abstract

The invention discloses a multifunctional nursing bed based on angle control and belongs to the technical field of medical equipment. From the demand of a turning-over function, human body turning-over is regarded as approximately fixed-axis rotation, and a nested combined bed frame and a turning-over mechanism thereof for realizing an approximately fixed-axis turning-over mode of a human body are provided. According to the multifunctional nursing bed, the left-right side turning-over function is achieved through two symmetrically-arranged series-connection combined mechanisms formed by crank sliding blocks and a swing rod, the sliding blocks are driven to be located between the two symmetrically-arranged combined mechanisms, the bottom space of the multifunctional nursing bed is effectively utilized, the number of driving motors is reduced, besides, a crank swing rod mechanism is designed at the bottom of the bed body, and a first fork arm is driven by a first driving assembly to swing and turn over around a rotating shaft of the first fork arm, so that an upper body plate is turned over, and as a driving bevel gear is mounted on the rotating shaft of the upper body plate, the driving bevel gear drives a driven bevel gear to rotate in the rotating process of the upper body plate; and the driven bevel gear drives the swing arm to swing so that a first side plate and a second side plate can synchronously rotate with the upper body plate.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a multifunctional nursing bed based on angle control. Background technique [0002] The multi-functional nursing bed needs to assist the bedridden people to exercise frequently and should be used by more than 90% of the population, and the angles of back support, rollover and bent legs, the movement trajectory and size parameters of each bed board should meet ergonomics Require. And existing nursing bed is in the process that the back is slowly raised, and the back mattress can be squeezed to the patient's waist and back; Pulling, the patient will feel extremely uncomfortable, and when the nursing bed rises or falls, if there is no side wing rising to protect the patient's body sides, the patient will slide to the sides and fall off the danger of the nursing bed. At the same time, the applicable population of the multifunctional nursing bed is the elderly with limited...
