A New Wristband Design for Cardiac Event Recorder and Telemetry System

Öz

With the system implemented, a telemetry system has been developed to assist in the follow-up and diagnosis of people with heart disease or those who are likely to have heart disease. In accordance with this purpose, the study that we carried out consists of three parts. These sections are respectively: Wireless ECG receiver design, Android interface design and computer interface design. In this study, the signals received through electrodes placed on the body are amplified and filtered, and then transformed into an analog signal that can be processed. The signal that is converted to digital with the help of microprocessor is provided wireless data transmission by sending to Bluetooth module. The ECG recording system is executed by providing a Bluetooth connection between the Android interface design and the wireless ECG receiver circuit. At the end of the recording process, the data is provided to be sent to the physician’s email address with the patient information. With the computer interface, Physician’s Emails automatic control is provided. With the detection of the new incoming e-mail, the patient information and ECG file were saved to the computer and the patient ECG graphic was drawn.

Kardiyak Olay Kaydedici ve Telemetri Sistemi için Yeni Bir Bileklik Tasarımı

Öz

Gerçekleştirilen sistem sayesinde kalp rahatsızlığı olan kişilerin veya kalp rahatsızlığı olma ihtimali olan kişilerin takibi ve teşhisinin konulmasına yardımcı bir telemetri sistem geliştirilmiştir. Bu amaç doğrultusunda gerçekleştirilen çalışma üç bölümden oluşmaktadır. Bu bölümler sırasıyla kablosuz EKG (Elektrokardiyogram) alıcı tasarımı, Android ara yüz tasarımı ve bilgisayar ara yüzü tasarımlarıdır. Bu çalışmada vücuda yerleştirilen elektrotlar aracılığı ile alınan sinyaller yükseltip filtrelendikten sonra işlenebilir analog bir sinyale dönüştürülmüştür. Mikroişlemci yardımıyla dijitale dönüştürülen sinyal Bluetooth modülüne gönderilerek kablosuz veri iletimi sağlanmıştır. Android ara yüzü tasarımı ile kablosuz EKG alıcı devresi arasında Bluetooth bağlantısı sağlanarak EKG kayıt sistemi gerçekleştirilmiştir. Kayıt işleminin sonunda veriler hasta bilgileriyle birlikte hekim E-mail adresine yönlendirilmesi sağlanmıştır. Bilgisayar ara yüzü ile ise hekim E-mailleri otomatik kontrolü sağlanmıştır. Yeni gelen E-mailin algılanması ile hasta bilgileri ve EKG dosyası bilgisayara kaydedilip hasta EKG grafiği çizdirilmiştir.
