Abstract

In (alpha,beta) coordinates defined by a back angle alpha and a knee angle beta, a pattern that connects between a coordinate point (0, 0) at which each of a back bottom and a knee bottom is horizontal and a coordinate point (alpha0,beta0) which is a final reaching point for a back lift-up operation and at which the back bottom is lifted up by a plurality of points is set, an optimal pattern which provides less slipperiness and less oppressive feeling is acquired beforehand, and a control section moves the back bottom and the knee bottom along the optimal pattern. This reliably prevents a carereceiver from slipping, regardless of subjective judgment by an operator or a carer, at the time of performing a back lift-up operation and back lift-down operation of an electric bed. It is therefore possible to prevent pressure from being applied onto the abdominal region and chest region of the carereceiver, thus relieving the carereceiver and carer of the burden.

Description

technical field [0001] The present invention relates to an electric bed in a nursing bed, etc., which can lift the back of the bed by electric power, and especially relates to an electric bed suitable for lifting the back without moving a lying caregiver, such as a patient, or suitable for The electric bed exerting pressure on the body of the cared person also particularly relates to a control method and a control device of the electric bed. Background technique [0002] In an aging society where the number of bedridden patients increases, it is necessary to erect the upper body of the bedridden patient for many reasons, such as medical examination, eating, watching TV and reading. Thereby a kind of electric bed has occurred, and this bed can make the back bottom and the knee bottom of sick bed lift up and down by electricity. However, the back raising or back lowering of the motorized bed moves or puts pressure on the patient's body. This creates an offset between the mov...
