Abstract:

Wheelchairs, trolley chairs, and potty chairs are essential for people with disabilities, patients, and elderly. These forms of equipments are specially designed to support specific needs of their users, such as moving, bathing, and resting, etc. Since the function of equipment is limitted, patients with multiple problems may need more than one single equipment to be properly supported, which make the caring processes more complicated because patients have to be transferred between equipment, also increase the cost on equipment. This paper presents a new design on a multi-purpose trolley chair to better support patient’s life. Multi-purpose trolley chair can be used as a lifting and transfering equipment, or supporting devices for moving, bathing of patients and elderly. The seat on multi-purpose trolley chair is seprated into 2 pieces and can be adjusted by a smart-locking system, the chair back can be flexibility rotated back and front, and the whole seating set is installed on a mechanic lifting mechanism to better fit and comfort patients with different sitting modes to satisfies required medical treatment positions or easier moving, Moreover, this device can be placed in the bedroom as a regular toilet seat, helping patients avoid having to travel far when they are alone. Combining with the use of computational software for structural analysis, such as NX and SAP2000, to optimize the design, the calculation and design process can be done quickly with the aim of reducing the weight of the vehicle while ensuring durability, rigidity, and safety during operation. Conducting this research is an initial basis to quickly bring the versatile patient care wheelchair product into practice.
