Review on Design and Development of Hydraulic Chair for Handicapped Person

Abstract: In many medical situations, it is necessary to lift patients. This need for assistance could be due to reduced patient strength as a result of an extensively invasive operation, inherent weakness, or old age. Generally, elderly or post-operative patients come to examinations in wheelchairs or with the assistance of a walker. In most cases, it is easier to help patients out of wheelchairs than to lift them up to the top of exam tables. To facilitate lifting of elderly or post-operative patients, it is necessary to design a device that is capable of safely transferring patients from a standing position on the ground to a level where they can easily get onto an exam table. To reduce patient anxiety, the device will include handles or another similar structure for patients to hold onto as they are being transferred. Finally, the device will be easy to operate and will minimize the required effort by the patient and medical personnel. In this paper we study the various research papers on design and development of hydraulic chair for handicapped person, the used the different technology for lifting the patients.
