Technology helps in health advances and thanks to it many lives can be saved. But it can be expensive, very expensive And, therefore, very far from the economic possibilities of the developing countries. Faced with this difficulty, there are people who do not give up. This is why we found the MOW (medical open world) NGO, to design and provide low-cost sanitary equipment to the developing countries).
Our first design is a low-cost incubator. Countries such us Ghana, Mali, Kenia, Sierra Leona and more actually have some of our incubators saving preterm babies. Where the alternative is a shoe box or an empty pumpkin (technique used in a high percentage of African hospitals), this is more than much.
The target is to control the main environmental factors to give the preterm baby a higher chance to survive. Temperature and humidity are the main factors to control and the chepeast ones. We use an air heater and a fan to distribute the air in the incubator atmosphere. Also a mist maker is used to nebulize the water in a recipient to increase the ambient relative humidity.
Our aim is to continiously improve the design to provide more functionalities and so, more chances to survive.
Origin of the idea
We are a group of young spanish engineers interested in technology. For some years, we spent our time playing around with nerdly ideas, but we all "heed the certain call" to put our effort and little knowledge in service of who may need it. That's how we came out with "In3ator". We are all giving part of our spare time to this project with the wish of making a little change.
There is still A LOT more to do. No matter how much you know or where are you from, if you also heed the call, don't hesitate to contact us (you can contact me at email@example.com).
