원격 수액모니터링 시스템의 주입량의 정확도에 영향을 주는 융합인자의 비교 분석 Comparative analysis of fusion factors affecting the accuracy of injection amount of remote fluid monitoring system원문보기
최근에는 COVID-19 인해 의료기관에서 원격으로 관리되는 환자케어 시스템의 보급이 증가되고 있다. 특히 수액 모니터링인 경우 환자의 안전과 간호사의 업무를 줄일 수 있는 시스템으로 병원에서 도입을 고려하고 있다. 현재 개발되어 있는 제품은 무게를 측정하는 로드셀 방식과 적외선 센싱으로 수액 방울을 검출하는 방식의 두 가지 제품이 있다. 각 제품은 동작원리, 센서의 종류, 크기, 사용법, 가격등의 차이가 있지만, 의료기관에서는 획득되는 데이터의 정확도에 관심이 높다. 본 연구에서는 센서 방식이 다른 두 가지 시제품을 제작하여 수액모니터링 장치의 핵심인 정확도를 실험하기 위해 시간당 총 수액량을 측정하였다. 또 외부의 움직임이 있을 경우 수액 측정값의 변화를 실험하여 측정방식에 따른 정확도를 평가하였다. 실험 결과 두 장치의 측정값 오차는 5% 미만의 차이가 있었고, 로드셀 방식은 저용량 측정값에서 적외선 방식은 고용량 측정값에서 차이를 보였다. 본 연구결과 수액모니터링장치의 센서방식에 따른 정확도 차이는 거의 없었고, 향후 의료기관에서 사용할 경우 정확도의 문제는 없을 것으로 사료된다.

Recently, the prevalence of remotely managed patient care systems in medical institutions is increasing due to COVID-19. In particular, in the case of fluid monitoring, hospitals are considering introducing it as a system that can reduce patient safety and nurses' work. There are two products under development: a load cell method that measures weight and a method that detects drops of sap by infrared sensing. Although each product has differences in operation principle, sensor type, size, usage, and price, medical institutions are highly interested in the accuracy of the data obtained.In this study, two prototypes with different sensor methods were manufactured and the total amount of infusion per hour was measured to test the accuracy, which is the core of the infusion monitoring device. In addition, when there was an external movement, the change in the measured value of the sap was tested to evaluate the accuracy according to the measurement method. As a result of the experiment, there was a difference of less than 5% in the measurement value error of the two devices, and the load cell method showed a difference in the low-capacity measurement value and the infrared method in the high-capacity measurement value. As a result of this experiment, there was little difference in accuracy according to the sensor method of the infusion monitoring device, and it is considered that there is no problem in accuracy when used in a medical institution.
