Intelligent systems to benefit fall-prone and dementia patients



Intelligent systems to benefit fall-prone and dementia patients

Engineering students at Ngee Ann Polytechnic and healthcare professionals at Khoo Teck Puat Hospital have jointly developed intelligent systems which will benefit patients who have dementia and are prone to falls. 

Three systems were developed for fall-prone patients. 

The first system measures the patient's reaction time which will predict the patients' probability of falling. 

The second and third systems work based on sensors. 

Overhead lights that are linked to sensors underneath the mattress will be fitted in the geriatric wards to prevent patients from falling. 

The light will be triggered and nurses alerted if the patient attempts to move to the edge of the bed. 

Two ultrasonic sensors will also be mounted on the ceiling in the toilets of geriatric wards to detect patients falling. 

When the patient falls, the sensor will trigger a buzzer to alert the nurses. 

The team have also developed an interactive game that trains attention and short-term memory of dementia patients. 

These prototypes are undergoing trials at the hospital and will be rolled out to the wards next year. 

Ngee Ann Polytechnic and Alexandra Health, which manages the hospital, have signed a three-year Memorandum of Understanding to develop more engineering solutions to benefit the healthcare sector.
