Ugandan engineers have created a “smart jacket” that can diagnose pneumonia faster than a doctor by measuring breathing patterns, temperature and breathing rate simultaneously, then sending the information to a mobile app.
The Mama-Ope (Mother’s Hope) kit was born when Olivia Koburongo, 26, had the idea after her grandmother was transferred from hospital to hospital until she was finally diagnosed with pneumonia. By the time of diagnosis, it was too late to save her. Koburongo thought the diagnosis had taken too long, and decided to seek a solution.
Koburongo took her idea to fellow telecommunications engineering graduate Brian Turyabagye, 24, and together with a team of doctors they came up with the “Mama-Ope” (Mother’s Hope) kit made up of a biomedical smart jacket and a mobile phone application which does the diagnosis.
Pneumonia—a severe lung infection—kills up to 24,000 Ugandan children under the age of five per year, many of whom are misdiagnosed as having malaria, according to the UN children’s agency UNICEF.
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.
