Update on Arthur Zang's works

August 13, 2012
Arthur Zang completed in June 2012 the assembly of 30 copies of the Cardio Pad with the financial support of the Cameroonian State (something rare enough in Africa not be noticed and applauded). Indeed, the Cameroonian government has allocated 20 million CFA francs (30,500 euros) to the engineer to materialize part of his project.

After traveling to China to acquire the necessary components for the manufacture of his invention, Arthur Zang managed to assemble 30 Cardio Pads in Yaoundé, Cameroon. The electrodes which are equipped with Bluetooth and that will be connected to the patients' chest have been manufactured, too. This system is important because it allows the transmission of heart rates to the Cardio Pad. Arthur Zang and his team must now succeed in connecting the Cardio Pad to operators' mobile networks with a license in Cameroon: MTN and Orange.

One will notice, among others, the quality of the design of the Cardio Pad which is a success. This shows that young Africans can combine performance, ergonomics and aesthetics in their work.

Arthur Zang is a young engineer in computer engineering, from Cameroon, who has developed a touchpad (Cardio Pad) for medical use. He was trained in Cameroon at the Ecole Nationale Supérieure Polytechnique (ENSP) in Yaounde.

While doing his academic internship at the General Hospital of Yaounde, in 2010, Arthur Zang becomes aware of the difficulties faced by Cameroonians in accessing care related to the heart. Indeed, there are approximately forty cardiologists for about 20 million Cameroonians. However, these cardiologists are often located in the cities of Yaounde and Douala; thus not always easily accessible, especially for patients living in remote cities. It is from this reality that this young engineer of 24 years (in 2011) will consider the design of the Cardio Pad.

In practice, the patient is connected to electrodes placed on his heart, which are connected to a module called Cardio Pad Acquisition Mobile (CAM) which, via a Bluetooth interface, transmits the heart signal to the Cardio Pad after the signal has been digitized. One can then read the heart beats, heart rate, and the intervals between each beat displayed on the Cardio Pad, etc. All these data are then stored in a file and sent to the cardiologist's Cardio Pad via a mobile telecommunication network.

Mobility and data storage provided by the Cardio Pad are two major advantages of the invention. Indeed, the cardiologist may not be in the hospital, but can instantly receive the results of a patient, make a diagnosis and administer the appropriate treatment from his Cardio Pad. This is telemedicine.

To achieve this, this brilliant inventor had to design a system for acquiring, processing and transmitting the cardiac signal via a mobile network (GSM for the moment). But he also had to develop a software (Mobile Cardio OCG) which aims at acquiring, amplifying and filtering a patient's heart rate. With no advanced training in electronics, Arthur Zang had to enroll in distance learning with an Indian University in digital electronics and embedded systems courses. At the end of this training he was able to design electronically the Cardio Pad touchpad. He had to order the components from China at a cost estimated at about 600,000 CFA francs (about 1,000 Euros). After assembling the various components, Arthur Zang then installed his operating system and software.

The Cardio Pad consists of a 10 inches LCD touch screen. However, the inventor plans to provide different sizes based on usage (7, 8 and 9 inches).

If not already done, let's hope that Arthur Zang is in the process of obtaining his patent from the OAPI (African Intellectual Property Organization) and / or WIPO (World Intellectual Property Organization) in order to protect his invention. Indeed, African inventors must also earn a living with their inventions.
