Abstract - The challenges faced during transferring the
have designed a multipurpose wheelchair that can work as wheelchair as well as a Stretcher.
patients exist from ancient times. People who get seriously injured or ill were carried by others by means of wooden stretcher with cloth or leather tied to it. Afterwards they were carried on wheels which reduced the effort of the people carrying the patients. Although we have evolved in the field of healthcare and technology we are not yet able to address this problem efficiently. Adopting various kinds of research methods helped us to obtain more information about hospital mobility aids and for data collection. Mobility aids are used for transportation of patients. Wheelchairs and stretchers are the most commonly used mobility aids for the movement of patients. Transferring the patients from wheelchair to stretcher or to the medical bed or vice versa is always an issue for the attendant or nurse. There is a revolution of wheelchairs available today driven by needs and desire of man.
The Automated Wheelchair Convertible Stretcher facilitates the disabled patients’ mobility & provides novel medical equipment for use in the Indian hospitals. The purpose of this design is to reduce the effort of the caretaker & provide a safer transfer for the patients in hospitals. Its construction is so easy and can be operated and maintained easily. We have used simple mechanism which is powered electrically to achieve the required motion. This project is the result of a design and development of a multifunctional Wheelchair that would perform all the required functions. Automated Wheelchair Convertible Stretcher is so made that it can be maintained & operated easily either by the patient or the operator according the comfort of the patient.
Hence we propose a design of Automated Wheelchair Convertible Stretcher which is a boon to the medical field. It is so made that it could be maintained and operated easily either by the patient or by the attendant according to the comfort of the patient. Our study shows that it is possible to save 50% space by the Automated Wheelchair Convertible Stretcher design. The product will thus likely be an efficient mobility aid in hospitals.
1.1 OBJECTIVES OF OUR INTENDED WORK:
To reduce precluding exertion of the patient.
To carry out the transformation process with utmost safety.
Key Words: Wheelchair, Stretcher, Wheelchair convertible stretcher, Mobility aid, Healthcare.
To decrease the cost by using gear mechanism instead of hydraulics, pneumatics or electronics.
1. INTRODUCTION:
To reduce the noise considerably during operation.
In simple words a wheelchair can be described as a structure having a set of wheels attached to a chair. Wheelchair is a device which can empower and enable a person with a disability to live a normal and independent life.
To attenuate space efficiently.
To consolidate the concept of wheelchair and stretcher.
Over the years wheelchairs have evolved rapidly from the manual wheelchairs to the powered wheelchairs. But still these wheelchairs have not been able to satisfy the needs of the disabled people. It is therefore critical that the problems of disabled be understood and accordingly wheelchairs are developed fulfilling their needs.
2. REVIEW OF LITERATURE: The author in [1] gives us various concepts regarding wheelchair convertible stretcher. Concept 1 enlightens us about a sliding tubular frame which is attached to the back rest of the wheelchair. A handle is provided in the back rest so that the user can pull it easily and can convert it into stretcher. Concept 3 gives us an insight to the hydraulic scissor lifter mechanism, so that the height can be adjusted according to the user’s convenience. A hydraulic scissor lifter mechanism lifts the entire wheelchair into stretcher. Concept
In India number of disabled individuals is increasing every year. Mobility aids are useful for patients for transportation. Wheelchairs & stretchers are the most commonly used medical equipment for the transportation of patients. So we
