A Literature Review: A Novel Human Vital Sign based Wheel Chair Cum Stretcher for Disabled Person

In the recent years a census indicates that around 700 million persons suffer from some kind of disability or handicap. There is an increase in the elderly population around the globe. This increase their need of support structures for enabling comfort and independent life. The phenomenon increases attention to the scientific community. A wheelchair cum Stretcher the pre-existing technique in this domain includes either wheel cum stretcher that are joined by linkages or mechanical systems. The disadvantage of this technique mainly involves high mechanical strength needed for modifying or conversion. So therefore a solution by incorporates wheelchair cum stretcher. Therefore the goal of the survey is to criticize the researchers and compare between the various types of mechanisms involved in the designing of wheelchair cum stretcher in the previous decade. Thus by this way we would like to compare between various approaches their pros and cons, thus helping the upcoming researchers to design a device as per the necessities overcoming the problems or constraints faced in the existing design.
