etc., wheelchairs and stretchers are frequently utilized. Depending on the needs, this design is a modified wheelchair stretcher. According to the needs, this device can be utilized to transform a wheelchair into a stretcher. This can be manually accessed. When the levers are pulled, the chair becomes a stretcher. According to the patient's and the doctors' convenience, the stretchers can be removed from the main frame, making it simpler to carry and access the patient. With the help of the folding mechanism, it is simpler to store several stretchers in the shape of chairs in a comparably small amount of space. Every day, there are more patients in the world. Therefore, it is dangerous for patients to be transferred from a wheelchair to a stretcher, a bed to a wheelchair, or vice versa, in hospitals. A wheelchair cum stretcher is required to improve the mobility of impaired patients and to supply cutting-edge medical technology for usage in hospitals.
A mobility aid is a tool created to assist persons who have mobility impairments in moving around or to generally improve their mobility. There are several walking devices that can help people who have trouble walking, as well as wheelchairs or mobility scooters for people who have a more severe impairment or who need to travel farther than they normally would on foot[4]. The white cane and guide dog have been used for many years by those who are blind or visually impaired. Other aids can be used to help with transfers or mobility inside a building or in areas where there are variations in level. The term "mobility aid" has typically been used to refer to low-tech mechanical devices. The phrase can also be seen in official papers, such as those that discuss different types of tax breaks. It describes those gadgets that allow for a degree of independence of movement akin to that of unsupported walking or rising from a chair. Wheelchairs that can be manually moved by the user or a companion[2]. Users can go forward and backward at rates determined by how much force they can use by manipulating the push rims. They can also turn left or right and pass over nearby dips and peaks. Four tiny wheels protrude from a small platform on a wheelbase chair, also called a scooter. The kind of chair that is put on this platform varies depending on the user's demands and disability; some are even made from a mold of the user in their ideal sitting posture. The wheelbase chair's controls are attached to a frame that curves upward from the platform's front to a height and position that is comfortable for the user. The top of the frame is coupled with a horizontal steering bar. A stretcher is a medical tool used to carry patients for a brief period of time. It features grips on either side of the stretcher's length to make it easier to carry[7]. A stretcher is a mobile bed on wheels used to move patients who are unable to walk or stand unaided. People who are in critical condition and accident victims are transported from one location to another using stretchers. The design is

1. INTRODUCTION A chair with wheels is a wheelchair. The device comes in many designs that allow for electric propulsion by motors or manual propulsion by the sitting occupant manually turning the rear wheels. The seat frequently has handles behind it so that someone else can push it. People who find it difficult or impossible to walk due to an illness, accident, or handicap use wheelchairs. A wheel bench is frequently used by people who have trouble standing and walking. The earliest human creations were the wheel and the chair[1]. A wheelchair is a wheeled mobility aid created specifically for people with disabilities. The machine can be moved manually by spinning the wheels by hand or automatically using a variety of systems[9]. People who find it difficult or impossible to walk owing to a physical or physiological condition, an injury, or a handicap use wheelchairs. Early wheelchairs were solely designed to facilitate a disabled person's movement from one location to another, but today's wheelchairs are seen as a means of both transportation and personal expression.
