Our Story

One of the most important ways of tackling and slowing down the spread of COVID-19, is the constant monitoring of potentially infected or non-critical patients.

We had talked with over 15 experts, including doctors, nurses, investors and manufacturers and they all agreed upon its importance. Currently, nurses inspect the patients from up-close and for the sake of everyone’s safety,  they have to change their protective covers after each inspection. However this cannot be fulfilled every time and due to time constraints as well, the number of routine check-ups - which should be hourly - drops down to 3 times per day.

Our solution lifts the weight off of nurses’ shoulders and keeps them away from the patients during the monitoring, because by using our self-developed glass frame, patients can take care of the measuring themselves, without the presence of a nurse.

In the span of 24 hours we created our 3D printed prototype glasses, which uses publicly available, simple sensors. The low cost of 20-40€ for a unit opens up the possibility of equipping all hospital beds as soon as possible.

The design is simple and intuitive, and it guides the user with light and voice signals. First, the infrared sensor measures the temperature at the forehead, and thanks to the light signals, it can instantly be known that the measuring was successful and how the temperature status changed. The regularity of breath is measured with a microphone placed under the nose and the lights pulse accordingly. Finally, the most important parameters, the oxygen saturation and pulse are measured with a pulsoximeter placed on the side of the glasses

The data is then uploaded to the hospital’s IT system, so that it instantly becomes available for doctors and nurses. If there is any error or false reading, alert signals could be sent to the nurses, to check up on the particular individual. This way nurses will have more time at their hands to deal with more critical cases, they need less protective gear and the chance of infection is also reduced.  We trust that our solution can offer a safer and simpler alternative to all hospital workers around the world.

Doctors also noted, that this solution not only applies to the COVID-19 situation, but can also work in peaceful times. Another important path to consider is the use in personal residencies by the general public. Once hospital capacities will overload, people will have to get over the difficult periods at home and our sensors could help remote monitoring for GPs and emergency doctors.
