Abstract

In this paper, a new biotelemetry system for a transcutaneous data communication between an implanted artificial heart with a control system and an external human-interfaced management system has been developed. A radio telemetry using radio frequency is a commonly used method in the conventional telemetry systems. But, it is not suitable for the medical applications because of not only an interference due to a radio broadcasting but also a harmfulness to the human body. In this paper, therefore, a new biotelemetry system applied to an artificial heart has been developed with the results of the recent research for an optical telemetry system based on the infrared light transmission with good skin permeability. The performance of the biotelemetry system developed has been assessed through mock circulatory experiments, and the clinical applicability has been also confirmed with the successful results in the animal experiments.

본 연구에서는 체내에 이식되는 인공심장 및 제어시스템과 체외의 환자관리시스템간의 정보교환을 위한 무선 통신시스템(Biotelemetry System)을 개발하였다. 일반적으로 무선 telemetry라고 하면 전파 telemetry를 의미할 정도로 전파를 이용한 방식이 보편화되어 있으나, 늘어나는 전파무선기기에 의한 전파장해 및 간섭현상과 무엇보다 인체에 유해한 단점으로 의료용 장비에의 응용에는 부적합하다, 따라서 본 논문에서는 최근 빛을 이용한 무선telemetry에 대한 연구결과를 응용하여 피부투과성이 좋은 근적외광(Infra Red Light)을 이용한 광통신 방식으로 인공심장용 무선정보 전달장치를 구현하였다. 개발된 시스템의 성능은 인공 심장용 모의순환실험을 통해 평가되었으며 아울러 동물실험에서의 성능평가로 임상에의 응용가능성을 확인하였다.
