Electrically propelled wheelchair stretcher

Abstract

The invention relates to the technical field of rehabilitation medical equipment, in particular to an electrically propelled wheelchair stretcher. The electrically propelled wheelchair stretcher comprises a backrest assembly, a seat assembly, a handrail assembly, a leg assembly, a pedal assembly and a chassis assembly. The backrest assembly comprises a backrest frame, the backrest frame is hingedto a seat cushion lower bottom plate, a spring shaft is mounted on a rear spring seat, a torsional spring is arranged on the spring shaft in a sleeving mode, one end of the torsional spring abuts against the backrest frame, and the other end abuts against the seat cushion lower bottom plate; an output shaft of a motor is fixedly connected with the spring shaft; a swing rod shaft sleeve is furtherfixed to the backrest frame, a rear telescopic rod is arranged in the swing rod shaft sleeve, a telescopic positioning sheet is fixed to the rear telescopic rod, the leg assembly comprises a leg frame, a front telescopic rod sequentially penetrates through the interiors of a front shaft sleeve and a front shaft sleeve base; and the handrail assembly comprises four connection rods, the first handrail connection rod is fixed to the outer end of the rear telescopic rod, one end of the fourth handrail connection rod is in pin connection with the third handrail connection rod, and the other end ofthe fourth handrail connection rod is fixed to the outer end of the front telescopic rod. By adopting the electrically propelled wheelchair stretcher, a single person can be straightly pulled and pushed to get on and off an ambulance, and the electrically propelled wheelchair stretcher is foldable.

Description

technical field [0001] The invention relates to an electric wheelchair stretcher, which belongs to the field of medical equipment. Background technique [0002] In recent years, natural disasters such as earthquakes and fires and daily accidents have occurred from time to time, often resulting in a large number of casualties and insufficient rescue personnel and insufficient medical equipment, resulting in greater harm due to the delay in transporting the injured. Stretchers for transporting the injured put forward higher requirements, that is, fast and convenient operation, fewer operators, less secondary damage to the injured, and high-efficiency and high-quality post-injury transportation. At present, the research on stretcher vehicles mainly includes folding stretcher vehicles, pole mechanism stretcher vehicles and multi-functional stretcher vehicles. The main characteristics of the above-mentioned stretcher vehicles are: light weight, simple operation, but occupy at lea...
