With the Apple Watch’s ECG-reading tech has made its way, wearable devices have moved a step forward and turned out to be genuine lifesavers. This new device developed by researchers from the Army Medical University and China Academy of Engineering Physics used two different light measurement techniques to build an accurate structure of the body’s blood circulation. It is great for quickly and accurately identifying strokes, one of the primary causes of death worldwide. As there is a time-bound situation in identifying the strokes for effective treatment, this is a great tool for physicians and potential future patients as well.
How This Device Works?
As per the Detian Wang, one of the researchers on the project, this hybrid diffuse optical device it has near-infrared diffuse optical spectroscopy and diffuse correlation spectroscopy to track the [body’s] total hemoglobin concentration, blood flow index noninvasively, and tissue oxygen saturation, which are useful in identifying the type of stroke at an emergency situation.
This device is equipped with near-infrared diffuse optical spectroscopy, also known as NIRS-DOS, which reads multispectral tissue-scattered light intensity signals to define the concentrations of things like water, tissue oxy-hemoglobin, and deoxy-hemoglobin. These measurements are used to track oxygen saturation and blood volume in tissues. To monitor the body’s hemoglobin level Diffuse correlation spectroscopy (DCS) is used. All of these Readings are quickly done using custom software developed by the team.
Useful at the Emergency Site
Although CT and MRI can be done in the hospital to diagnose stroke, it might miss out the effective treatment due to pre-hospital delay and limited treatment window of 3 to 4.5 hours. But through this optical diagnostic device it can be done faster as it is sensitive to hemodynamic parameters, safe, non-invasive, cheap, and portable which can be placed in the ambulance, therefore it is most useful at the emergency site.
The research team has plans to sell the technology, although further clinical studies are yet to be conducted. It remains to be seen what type of finished device would take.
