Mechanically Operated-Wheelchair convertible stretcher and walker

Mechanical Engineering

The problem of transferring the patients exists from prehistoric times. An adaptive technology known as wheelchair is used to deal with loss of mobility for the patients who are not able to walk normally due to some injury or some other age related walking disabilities permanent or under treatment, Later they were carried on wheels which reduced the effort of the person carrying the patients. Though we have evolved in the field of health care and technology we are not yet able to address this problem efficiently. Mobility aids are used for carrying the patients. Wheelchairs, stretchers and walker are the most generally used mobility aids for the movement of patients. Transferring the patients from wheelchair to stretcher or else when they want to walk with the help of walker or to the medical bed or to stretcher is always an issue for the attendant or nurse. There is a wide range of wheelchairs available today driven by needs and desire of man. Hence we suggest a design of wheelchair convertible stretcher and then to a walker which is a boon to the medical field. It would be maintained and operated easily either by the patient as per his wish of walking through walker or sitting on wheelchair or by sleeping on stretcher, by the attendant according to the comfort of the patient.
