Imajine yon avni kote yon sistèm ka detekte nan yon segonn si yon tibebe ki fèk fèt gen lajònis, yon maladi ki afekte 60 pousan nan ti bebe epi ki ka mennen nan domaj nan sèvo ak pèt tande nan ka grav. Imajine ke sistèm lan imedyatman kòmanse yon rejim tretman ak notifye enfimyè a atravè mesaj tèks. Tout twa senaryo yo kounye a posib gras ak efò chèchè yo soti nan Irak ak Adelaide.
Enjenyè ki soti nan University of South Australia ak Middle Technical University te fèt lojisyèl D 'ki ka byen dyagnostike lajònis nan yon bat je, otomatikman limen limyè ki ap dirije ble pou anpeche lajònis, epi voye dyagnostik la kòm yon mesaj tèks bay paramedik yo.
Jaundice is a common disease in newborns, especially premature babies, and there is an excess of an orange-yellow pigment called bilirubin in the blood. It usually resolves quickly when a baby's liver grows enough to expel it from the body.
However, in severe cases of jaundice, due to sickle cell anemia, blood disorders and deficiencies of certain enzymes, the disease is often treated with phototherapy, which uses fluorescent blue light to break down bilirubin in the baby's skin.
Inivèsite Sid Ostrali enjenyè deteksyon aleka Pwofesè Javaan Chahl te di lajònis te patikilyèman répandus nan peyi devlope yo, kote souvan pa te gen okenn ekipman oswa anplwaye medikal ki resevwa fòmasyon pou trete li efektivman.
Professor Chahl said: "Using image processing techniques extracted from the data captured by the camera, we can inexpensively and accurately screen newborns for jaundice before blood tests are performed."
"When bilirubin levels reach a certain threshold, a microcontroller triggers blue LED light therapy and sends the details to the phone."
"This can be done in a second, really, it can have a big impact in severe cases and, if not treated quickly, can lead to brain damage and hearing loss."
Chèchè yo te teste sistematik 20 tibebe ki fèk fèt ak lajònis nan yon inite swen entansif nan Mosul, Irak. Dezyèm seri done yo kolekte 16 imaj tibebe ki fenk fèt, nan yo 5 yo te an sante ak rès yo te lajònis. Sistèm nan te teste tou avèk siksè sou kat mannequin adisyonèl ak ton po blan ak mawon, kèk ak ak san pigmantè lajònis.
"Previous research using sensors to find non-invasive ways to detect jaundice has failed. Tried methods are unreliable, costly, inefficient and, in some cases, cause infections and allergies where the sensor needs to touch the skin," he said. Professor Chahl said.
"Our system overcomes these hurdles, instantly detecting jaundice based on a novel digital color representation, enabling high diagnostic accuracy at relatively low cost. It can be used in hospitals around the world and without laboratory facilities and well-trained are widely used by medical staff in medical centers."
