Abstract

This study attempted to minimize the risk of hospital infection by ultrasonic gel by using hand sanitizer with microorganism removal effect as an ultrasonic propagation medium. As a research method, Near field group, Vertical distance, and Horizontal distance evaluations were conducted using various probe covers on Samsung Medison's R7 ultrasonic equipment, and through grayscale evaluation, we tried to find the ethanol content of the hand sanitizer that can obtain an image that is most similar to the grayscale level of the ultrasonic gel. As a result of analysis using the Image J program, the combination of Latex cover and 70% ethanol gel was the best in terms of image quality, and this combination is thought to provide an effect of preventing infection while maintaining image quality similar to that of using ultrasonic gel.

본 연구는 미생물 제거 효과를 가진 손 소독제를 초음파 전파 매질로 활용함으로써, 초음파 젤에 의한 병원감염의 위험성을 최소화하고자 하였다. 연구방법으로 Samsung medison사의 R7 초음파 장비에 다양한 프로브 커버를 사용하여 근거리 영역, 수직거리, 수평거리 평가를 진행하였고 회색도 평가를 통해 초음파 젤의 회색도와 가장 유사한 영상을 얻을 수 있는 손소독제 에탄올 함량을 찾고자 하였다. Image J 프로그램을 이용하여 분석한 결과 Latex cover와 70% 에탄올 젤 조합이 영상 화질 측면에서 가장 우수하였으며 이 조합은 초음파 젤을 사용한 경우와 유사한 화질을 유지하면서도 감염 예방 효과를 제공할 수 있을 것으로 사료된다.
