Samhlaigh todhchaí inar féidir le córas a bhrath laistigh de soicind an bhfuil buíochán ag nuabheirthe, galar a théann i bhfeidhm ar 60 faoin gcéad de leanaí agus a bhféadfadh damáiste inchinne agus caillteanas éisteachta a bheith mar thoradh air i gcásanna tromchúiseacha. Samhlaigh go gcuireann an córas tús le córas cóireála láithreach agus go dtugann sé fógra don altra trí theachtaireacht téacs. Tá na trí chás indéanta anois a bhuíochas le hiarrachtaí taighdeoirí ón Iaráic agus Adelaide.
Tá bogearraí íomháithe deartha ag innealtóirí ó Ollscoil na hAstráile Theas agus an Mheán-Ollscoil Theicniúil ar féidir leo an jaundice a dhiagnóiseadh go cruinn i bhfaiteadh na súl, soilse gorma stiúir a chasadh go huathoibríoch chun an buíochán a chosc, agus an diagnóis a sheoladh mar theachtaireacht téacs chuig paraimhíochaineoirí.
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.
Dúirt an t-innealtóir cianbhraite de chuid Ollscoil na hAstráile Theas, an tOllamh Javaan Chahl, go raibh buíochán an-choitianta i dtíortha i mbéal forbartha, áit nach raibh trealamh ná foireann oilte leighis ann go minic chun é a chóireáil go héifeachtach.
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."
Rinne na taighdeoirí tástáil chórasach ar 20 leanbh nuabheirthe a diagnóisíodh le buíochán in aonad dianchúraim i Mosul, an Iaráic. Bhailigh an dara sraith sonraí 16 íomhá de leanaí nuabheirthe, a raibh 5 cinn acu sláintiúil agus an chuid eile buíochán. Rinneadh tástáil rathúil ar an gcóras freisin ar cheithre mhainneachtain bhreise le toin chraiceann bán agus donn, cuid acu le lí buíochán agus gan lí.
"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."
