Four years have been necessary to develop a complete device that could be used in hospitals.

"Here you can see the different versions of the device. This is the prototype in 2010, this is the second version in 2012, with 6 tracks. There are several types of electro-cardiogram: one track, with a single cardiac signal; 6 tracks; or 12 tracks.

We started with one signal. Then we went to six. And then we continued the development of the product until 2014, when we had the first complete version, a 12-tracks electro-cardiograph, which contains all the data necessary for the production of a heart diagnosis.

In 2014, we started working on the certification and homologation of the device to start its commercialization, outside Cameroon in 2015, and inside Cameroon in 2016.

The Cardiopad kit, as you can see, consists of several elements: a pad, which is the main element, electrodes, a cable, a solar panel (yellow), that allows to charge the device in case of power failure.

Beyond the kit, there is something very important: the platform. The device itself allows the cardiac examination to be performed, but it must be interpreted remotely by a cardiologist. A set of servers collect the various examinations performed with the Cardiopads and transfer these data to the cardiologist.

We also developed a small application that runs on the cardiologist's phone and downloads data related to the information the cardiologist must interpret, the plot, blood pressure, as well as the symptoms that were collected during the cardiac examination."
