PROBLEM
DEFINITION
Transferring disabled person from wheelchairs to
stretchers or while they are wanting to walk with the
help of a walker or on a medical bed or stretcher is
always a problem for the operator or nurse. A wide
variety of wheelchairs are available today, driven by a
person's needs and desires but can not be convertible
from one form to another..
CONVERTIBLE
WHEELCHAIR
WE propose the design of a convertible
stretcher for wheelchairs and then walkers,
which is beneficial for medical field. It would
be easily maintained and operated either by
the patient according to his wish to walk with
a walker or by sitting in a wheelchair or
sleeping on a stretcher by staff according to
the patient's / disabled person comfort.
FOLLOWING ARE THE MAIN OBJECTIVES OF WORK.
OBJECTIVES
Satisfying the needs of the disabled people.
Make it cheaper by using new mechanism.
Works reliably under different operating conditions.
To save space.

With passing of time technology influences these inventions. Technology is knowledge of making things
easier and s problems solver.
So as technology emerges, many people to demand more to make their lives much easier and more
comfortable, especially for our PWD (person with disability). Some used a light material, or it can be ecofriendly material, also comes with different designs to get it to the people. Devices used by the patient to
stand and provide support to the patient while walking and stretchers mobile devices used to transport
patients from one place to another. These medical mobility aids are used in hospitals and clinics to help
patients.
The stretcher has a simple design, and the patient needs it assistant support during transport from one
place to another. While the walker is used by the patient to walk without any aid of any aid and wheelchair
is designed so that the device can be operated by any patient by hand or with someone's help.
WORKING OF WHEELCHAIR
The uniqueness of this design is that when the product is in stretcher or bed mode, the height will match the conventional
bed. The height is adjustable for a bed, stretcher or wheelchair or any desired height. Conversion from wheelchair to bed or
stretcher or vice versa can be done by both the patient and the handler.

This project would help people with disabilities to manage themselves easily.
Loss of transportation time and would be able to take the convertible wheelchair anywhere want.
It is quite affordable so anyone can easily get and use it.
A wheelchair can be used in a hospital for temporary use for some patients. Also, because crutches are easy to use.
Our study shows that 80% of space can be saved when using a wheelchair. A convertible stretcher instead of using a
walker and wheelchair stretcher separately.
This design eliminates steps transferring patients from a wheelchair to a stretcher and vice versa, as caring for disabled
people becomes difficult.
Our design will thus be an effective mobility aid for the medical field adding walker features would make the product
more reliable, more innovative and could satisfy patient needs to a much higher degree.

CONCLUSION
“to make our society more independent and able to fulfill its own needs
through the field of mechanics. "
The main goal of this product is to make the assistant's life easier
and ensure that the patient is not injured during treatment
process. This product eliminates the step of moving the patient
from the bed or gurney to the wheelchair and vice versa. On the
contrary, we could make the disabled person's life more fulfilling
and independent.
