Handing over of Auto Pressure Alarm for wheelchairs to CRP
Four Auto Pressure Alarm device for wheelchair, designed and developed by a research team of the Department of Biomedical Physics & Technology of the University of Dhaka, were handed over to representatives of the Savar based Centre for Rehabilitation of the Paralysed (CRP) on 5 April last. Chairperson of the department Mr. Md Abdul Kadir, Research group leader Honorary Professor Dr. Khondkar Siddique-e Rabbani and developer of the device Research Engineer Md. Moniruzzaman handed over the items on behalf of the department. Teachers and researchers of the department were present at the event.
A paralysed patient sitting on a wheel chair has to lift the body using both hands for a certain time after a regular interval of time. Otherwise pressure sores develop, leading to gangrene and eventual death. The Dhaka University team designed and developed a pressure sensor and necessary electronic circuitry employing microcontroller technology to give specific sound alarms to the user at specified time intervals. Fixed into locally made wheel chairs by CRP, this will provide a big relief to paralysed patients, extending their lives.
