A team of Ugandan engineers have invented a “smart jacket” that diagnoses pneumonia faster than a doctor, offering hope against a disease which kills more children worldwide than any other.
This idea came to Olivia Koburongo, 26, after her grandmother fell ill, and was moved from one hospital to another before being properly diagnosed with pneumonia.
Koburongo took her idea to Brian Turyabagye, a fellow telecommunications engineering graduate, and a team of doctors who came up with the “Mama-Ope” (Mother’s Hope) kit which is made up of a biomedical smart jacket and a mobile phone application which does the diagnosis.
Pneumonia, a severe lung infection, has been the leading cause of death in children under five around the world, taking the life of one child every 23 seconds.
A lack of access to laboratory testing and infrastructure in poor communities means health workers often have to rely on simple clinical examinations to make their diagnoses.
With the easy-to-use Mama-Ope kit, health workers merely have to slip the jacket onto the child, and its sensors will pick up sound patterns from the lungs, temperature and breathing rate. “The processed information is sent to a mobile phone app (via Bluetooth) which analyses the information in comparison to known data so as to get an estimate of the strength of the disease,” said Turyabagye.
The jacket, which is still only a prototype, can diagnose pneumonia up to three times faster than a doctor and reduces human error, according to studies done by its inventors.
Traditionally doctors use a stethoscope to listen for abnormal crackling or bubbling sounds in the lungs, however if medics suspect malaria or tuberculosis – which also include respiratory distress – the time lost treating those rather than pneumonia could prove deadly for their patient.
“The problem we’re trying to solve is diagnosing pneumonia at an early stage before it gets severe and we’re also trying to solve the problem of not enough manpower in hospitals because currently we have a doctor to patient ratio which is one to 24,000 in the country”, said Koburongo.
