A new multi-parameter sensor for detecting and monitoring bedsores or otherwise called pressure ulcers has been developed by the collaborative effort of GE Global research and the U.S. Department of Veterans Affairs (VA).
Ting Yu, principal investigator on pressure ulcer prevention and care program, said, "The device we have developed integrates multiple sensing and data analysis capabilities to help detect the earliest signs of ulcer formation. It also provides a more objective and comprehensive assessment of the wound to understand its progression."
Elevated temperature on the skin alerts the onset of infection or healing depending on where the heat around the wound is produced. A thermal sensor for spotting the elevated temperature is embedded in the handheld portable device.
A visual light sensor gives details on the color and texture of the skin, while a hyper-spectral light sensor estimates the amount of oxygenated and de-oxygenated hemoglobin below the test site.
The size and nature of the ulcer is mapped by 3D and a vapor sensor identifies gases released by an ulcer.
"Pressure ulcers are a very pervasive, but also very preventable condition for hospital patients. We're now testing this device with the VA in a clinical setting to see if it provides the kind of information that will help hospitals reduce and even one day eliminates pressure ulcers from developing with patients," said Ting Yu.
