AfterStroke

The technology developed by scientists at the Institute of Biomedical Engineering of Kaunas University of Technology can synchronously register photoplethysmograms and biomechanical (physical activity) signals. The data is collected on the wrist with the help of a wearing device and read through the USB port during charging. The main purpose of this device is to monitor the post-stroke condition to avoid complications.

According to KTU researchers, about 10,000 cases of stroke are diagnosed in Lithuania every year, 80% of which are ischemic. One-third of ischemic strokes are associated with atrial fibrillation. Early detection of atrial fibrillation and administration of blood-thinning medications reduces the risk of thromboembolic stroke and other embolic events by two-thirds.

To monitor himself or herself after stroke patience need to wear the device for a long time. When the device finds arrhythmia, it alerts the user to put the bracelet's buckle to the abdomen and the thumb on the screen sensor. By doing this person creates the the closet circuit to monitor the heart parameters.

The design of the device began with an analysis of the existing prototype and existing analogs. The device usage and circumstance scenario was also analyzed to optimally elucidate the range of possible solutions. After several creative sessions, concept sketches of the device were presented in an attempt to present creative guidelines. In the later stages of creation, the presentation of ideas was detailed, and CAD models with integrated internal components were developed.
In order to create a proper device design with the best characteristics, pilot models were 3D printed.

To shape the proper habituation, ergonomics was very important. The final version is ergonomic and doesn't cause inconvenience in daily use of the device. Another task in creating the design was the aesthetic appearance. It was essential to maintain a laconic, uncluttered form, but also to strive for exclusivity.
