PU sensor, for better assessment of the risk of decubitus ulcers

We have newly added a PU sensor to the range that uses a proprietary method and tool to assess blood flow in surface tissue. The technique is based on photoplethysmography (PPG), a procedure where the skin is illuminated and the reflected light is measured. This is an established technology that is used in heart rate monitors (HRM watches) and other devices.

The PUsensor has a sensing unit that is embedded in a thin, soft disk that is applied to the back. The device's patent-pending method allows healthcare professionals to assess blood flow with and without the application of a patient's body weight. The medical device operates independently and the method does not require staff monitoring during use. An embedded algorithm then evaluates the comparative measurements and generates a patient risk profile assessment based on blood flow.

The PU sensors are CE marked.


The ability to better predict which patients are at risk of developing pressure ulcers allows professionals to apply preventive measures with a greater degree of accuracy. This allows care providers in hospitals and nursing homes to take preventive measures where they are most needed. This offers a number of benefits to the patient, the healthcare system and society. The PU sensor examines PIV, the body's physiological defense mechanism against innocuous pressure, and is an objective complement to the subjective assessments performed today. Research shows that about 20% lack PIV and are in the risk zone of developing decubitus.
