Kardiyovasküler rahatsızlığı olan hastalarda, EKG (Elektrokardiyografi) kaydının ve nabız verisinin takip edilmesi gerekmektedir. Hastanelerde sıkça kullanılan EKG cihazları kağıt üzerinde çıktı vermekte fakat bilgisayar ortamına veri aktarımı yapamamaktadır. Bu durumda hastaya ait verilerin saklanması, karşılaştırılması ve analizi mümkün olmamaktadır. Günümüzde kullanılan taşınabilir holter cihazları genellikle ağır ve hastaya rahatsızlık verecek boyutlardadır. Kullanılan uzun kablolar hem gürültüyü artırmakta hem de hastayı rahatsız etmektedir. Tasarlanan yeni nesil cihazların bir kısmında da kontrol ünitesi ve sensörler ayrık kartlarda olup kablolarla bir araya getirilmektedir. Bu durum gürültü eklenmelerine neden olmaktadır. Bu çalışmada; hafif, ergonomik, tek kart üzerinde bütünleştirilmiş, kısa elektrot kabloları kullanan EKG/Nabız test cihazı tasarlanmıştır. Cihazı, göğüs kafesi ortasına yerleştirecek ergonomik bir kılıf üretilmiştir. Gömülü sistem kullanılarak tasarlanan cihazda, kullanıcıdan alınan veriler Python dilinde oluşturulmuş bir yazılım kullanılarak bilgisayara ve bir veri tabanına kaydedilmiştir. Hastaya ait veriler, anlık hasta takibi için oluşturulan mobil yazılım sayesinde, uzman doktora aktarılabilmektedir. Yapılan tasarım, özellikle yoğun bakım ünitelerinde hasta takibi için oldukça faydalı olacaktır.

Embedded System Based Portable Device Design for Measuring ECG/Pulse

Öz

In patients with cardiovascular disease, ECG (Electrocardiography) recording and pulse data must be monitored. ECG devices frequently used in hospitals provide output on paper but cannot transfer data to a computer environment. In this case, it is not possible to store, compare and analyze patient data. Portable holter devices used today are generally heavy and are of a size that will cause discomfort to the patient. The long cables used both increase noise and disturb the patient. In some of the new generation devices designed, the control unit and sensors are on separate cards and are combined with cables. This causes noise to be added. In this study; a lightweight, ergonomic, integrated on a single card, ECG/Pulse test device using short electrode cables was designed. An ergonomic case was produced to place the device in the middle of the rib cage. In the device designed using an embedded system, the data received from the user was recorded on the computer and a database using software created in Python. Patient data can be transferred to the specialist doctor thanks to the mobile software created for instant patient monitoring. The design will be very useful for patient monitoring, especially in intensive care units.
