S'pore researchers invent "intelligent system" for change of patients' diapers

Xinhua, August 12, 2015 Adjust font size:

Researchers from the Institute of Bioengineering and Nanotechnology (IBN) in Singapore have invented an "intelligent continence management system," which alerts caregivers by SMS when the patients' diapers are soiled, the institute said on Wednesday.

The system comprises a thin disposable sensor strip, a compact wireless transmitter, a receiver and software, which has the potential to improve the care of elderly and bedridden patients.

"Lying in soiled diapers for prolonged periods is not only uncomfortable and unhygienic, but may also cause skin rashes and infection for the wearer," the institute said.

"While increasing the frequency of diaper checks and changes may help to reduce this problem, it would also add to the workload of caregivers," said IBN Executive Director, Professor Jackie Y. Ying, who led the research effort.

Timely replacement of soiled diapers is a challenge for caregivers of patients who are unable to communicate this need, such as those who suffer from aphasia, the loss of speech after a stroke or brain injury.

IBN's sensor, which comes in the form of a thin, lightweight strip of metal, plastic and paper, can be easily integrated into the adult diapers currently available in the market to facilitate timely diaper change. The wireless transmitter, which is connected to the sensor, can be easily attached and removed for reuse.

IBN conducted a clinical validation of the prototype on 20 elderly residents in 2013, the results show that system works well.

The technology has been licensed in March for commercialization, the institute said.

"Our diaper sensor would contribute toward better management of elderly and bedridden patients in nursing homes, hospitals and at home," Ying added. Endi
