Stand-up and lie-flat wheelchair with turning function

Abstract

The invention relates to a standing and lying type wheelchair with a turnover function. A foot supporting mechanism is rotationally connected with a cushion frame and a wheelchair frame; the cushion frame is placed on the wheelchair frame through rollers; a turnover mechanism is arranged on the cushion frame; the cushion frame is rotationally connected with a left backrest frame and a right backrest frame; a running mechanism, the turnover mechanism, a standing mechanism and a lying mechanism are connected with a control structure respectively, so that turnover, standing, lying and universal running control are achieved. A lying function is achieved through the cooperation of two motors of a back raising mechanism and the foot supporting mechanism, and a single back raising function can be achieved by individually operating one motor; moreover, anti-tilting wheels are mounted behind rear driving wheels, and front anti-tilting wheels are additionally arranged at the lower part of a foot supporting frame in front of small universal wheels, so that the functionality and the safety of the wheelchair are improved. The turnover function is combined to the standing and lying type wheelchair, an automatic timing turnover function is achieved by the simultaneous overturning of a single backrest and a cushion, the long-term stress on the hip and the back of a bedridden patient is relieved in an assisting way, the occurrence probability of bedsore is reduced, and the burden on a nurse is reduced.

Description

technical field [0001] The invention relates to a multifunctional electric wheelchair, in particular to an electric wheelchair with the functions of turning over, standing and lying flat.

It is not only a means of transportation, but also enables them to participate in social activities and physical exercise, meeting the needs of the disabled. For patients who have not recovered the ability to stand and walk independently, it is necessary to give appropriate standing, lying down and turning over to relieve the obstruction of blood circulation caused by sedentary and long-term bed rest, relieve the pressure on the buttocks, and thereby reduce the incidence of bedsores. Wheelchairs currently on the market are varied, including electric wheelchairs with lying and standing functions, but lack electric wheelchairs combined with the function of turni...

AI Technical Summary

Problems solved by technology

There are many kinds of wheelchairs on the market at present, including electric wheelchairs with lying and standing functions, but there is a lack of electric wheelchairs combined with the function of turning over

For sedentary and bedridden patients, nurses need to turn over and pat their backs regularly to prevent bedsores, which is time-consuming and laborious and the effect is uneven

Most wheelchairs do not have seat cushions that tilt inward when they are in a sitting position, which also makes it easy for patients who have been bedridden for a long time to slide down, making it difficult to maintain a sitting position
