The Cardiopad: an African invention to save lives

Professor Samuel Kinguè

Professor Samuel Kinguè, who is the head of the cardiology unit of the Yaoundé General Hospital, has tested and endorsed the Cardiopad:

“I have tested the Cardiopad and the results are quite satisfactory. According to World Health Organisation (WHO), cardiovascular diseases are the primary cause of death in western countries and will soon become a huge concern for African countries as well. Therefore, an invention like the Cardiopad should be supported. It has numerous advantages: it allows distance consultations and can also be adjusted for the treatment of other diseases”.

A young Cameroonian engineer has built the first fully touch screen medical tablet that could soon save many African lives. He first has to find the necessary funding to mass-produce the device.

In a country that has only 30 heart surgeons for more than 20 million people, the dream of Arthur Zang, a 24-year-old Cameroonian engineer, is to facilitate the treatment of patients with a heart disease across Cameroon.

Save lives
In 2010, he created a digital tablet known as Cardiopad: “It’s the first fully touch screen medical tablet made in Cameroon and in Africa. It’s an invention that could save numerous human lives”, explains Arthur Zang.

In fact, Cameroon’s thirty heart specialists are all based in either Douala or Yaoundé, the country’s economic and political capitals. Heart patients often have to travel across the country for a consultation.
Appointments sometimes must be made months in advance, leading to death of some patients.

Hassle of travelling
The Cardiopad solves this problem by enabling medical examinations to be performed remotely and the results transmitted electronically, saving patients the hassle of having to travel to the city.

Arthur Zang explains that the Cardiopad is above all a scientific project. He started his research three years ago and carried out several scientific tests that were validated by the Cameroonian scientific community. “The reliability of the Cardiopad is 97.5%”, he says.

Distance consultation
In practice, the Cardiopad is a device that can perform tests such as the electrocardiogram (ECG). The medical tablet also makes it possible to wirelessly send the results of the tests from remote locations to the specialist who will then interpret them.

“The tablet is used as a classical electrocardiograph device: electrodes are placed on the patient and connected to a module that, in turn, connects to the tablet. When a medical examination is performed on a patient in a remote village, for example, the results are transmitted from the nurse’s tablet to that of the doctor who then interprets them.

Digitalised and transmitted
Software built into the device allow the doctor to give computer assisted diagnosis”, explains the young engineer.

Pointing out the differences between the Cardiopad and the classical electrocardiograph, Arthur Zang explains: “The Cardiopad has more functions. With the classical electrocardiograph, the results were usually printed on paper and handed to the cardiologist for interpretation.

It wasn’t possible to send or save the results electronically. With the Cardiopad, the results are digitalised and transmitted. There is no need to print them, the heart surgeon can interpret them, even remotely, from his tablet and then send the diagnosis and prescribed treatment”

“The Cardiopad will cut down the cost of examination. We intend to sell the device for 1500 euros, while the current price for an electrocardiograph device is 3800 euros. If hospitals purchase the device at a low price, they will be able to lower the prices of medical examinations”, Arthur Zang hopes.

However, there is still the issue of energy, as many of the country’s remote regions do not have access to electricity. “The Cardiopad is equipped with a battery that can independently power the machine for more than seven hours”, the engineer assures.

He further explains that a prototype and sample of device is already available. “We are currently producing the first units of the device which will be available for hospitals before July”, says the young engineer who is still looking for funding to mass-produce the Cardiopad. “Besides the funding, I am also looking to start a company to help improve the medical care system in Cameroon”, he concludes.

Hi prof,
Congratulations on finding what is needed among health practitioners. I think this tool is very helpful especially in rural areas and away from the heart doctor. Tools like this are very helpful not only for the people of Cameroon or Africa, but in other countries as well, even though developed countries. And expected, discoveries like this much done for other uses in medicine. The main problem of the settlement of health in developing countries, not the lack of a specialist merely, but the lack of support equipment for the diagnosis.

Sweet blog! I found it while surfing around on Yahoo News. Do you have any suggestions on how to get listed in Yahoo News? I've been trying for a while but I never seem to get there! Thanks. ,

I feel so happy to see this post. I really want to appreciate the young Cameroonian Engineer who worked really hard to get a tablet like this as a result to save many lives in Africa. I hope and strongly wish that he gets enough sponsors to produce the device massively. Thanks a lot.

Well done to Arthur Zang, for this exceptional innovation.. I really believe you must open an IndieGogo project.. to get the funding you need. I am sure this will be well supported.

Congratulations ¡¡¡ It is a very good device for the poor and far away population.
I am interested in more information to use your medical device in my country.

Well done Arthur Zang. I am proud of your achievement and hope that this will encourage other Cameroonians and Africans in general to overcome their inertia in the area of science and technology and revive those potentials that surely lie somewhere inside the people of that great continent. I pray that any intervention by the government or outside forces should aim at giving this invention all the support it needs for the benefit of mankind.

Anonymous 28 February 2012 - 8:16pm

Great job,
I believe in the future every hospital will need this device

Che Sunday 28 February 2012 - 5:19am / USA

The millions that the thief at the helm of government spends a day in Europe could fund the production of this device. Mark my word, the chinese that have flooded the country are now producing this product to ship it back to Africa.Legal experts in the diaspora better get to this kid and ask him to sit on this golded egg tight. What a blessed nation handed to a bandit.

H. Asare-Kwakye 13 February 2012 - 10:26pm / USA

This is excellent invention and I need more information. It will cut down most of the hospital visits. I hope he has patented it before someone steal idea. Where can we see the prototype and actually perform some Testing?
