심혈관계 질환의 발병 위험요인 분석이 가능한 맥진기는 한방 의료기기에서 대표적인 연구 분야 가운데 하나이다. 그러나 기존의 대부분의 센서 기반의 맥진기는 측정시의 맥박 박동처와 센서부의 접촉상태에 따른 편위, 검출된 파형의 부정확성 및 파형분석의 어려움 등에 있어서 문제점이 발생한다. 따라서 본 논문에서는 맥동에 의해서 유발되는 모세관 시험액의 상태 변화를 촬영한 맥동 영상을 분석하여 환자의 맥파의 측정이 가능한 맥진기를 제안한다. 제안한 맥진기의 성능 평가를 위해서는 추출된 맥파로부터 맥파 분석에 필수적인 5가지 특징점에 대한 추출률을 측정한 결과 성공적인 결과를 보였다.

This paper described the establishment of the basic data for the design of the transducer for the detection of plethysmogram, the structure of pulsimeter utilizing the designed transducer and the clinical usefulness of detected waveform of the optical detection method can be utilized as an information of cardiovascular system as physiological theoretical waveform of aorta, and derivative of plethysmogram by piezo electric elements clearly shows the information of incisura which does not appear at the old age and this makes the measuring of ejection time to be easy. The ejection time of average for 42 persons shows 0.324 $\pm$ 0.027 sec. and this value is in good agreement with the theoretical value, and the possibility of measuring the velocity of pulse conduction has been studied.

The existing USB connection type of the clip-type pulsmeter equipped with a Hall sensor and a permanent magnet does not have any error or malfunction to measure the pulse wave. The property of the wireless networking system communicating the pulse wave data through the wireless LAN communication by combination USB with Ethernet and Ethernet to Wi-Fi converting system instead of existing USB connection method was investigated. There are exited that the patient needs to stay at close site of the desktop PC without USB connector and the wireless transfer and receiver networking system has pulse wave measurement SW to receive the pulse wave data. Thus it is expected that the study becomes helpful to measure and transfer the exact pulse wave of the patient in a comfortable pose at close range.
