Abstract

During the medical ultrasound exercise at school, we randomly select parts of the ultrasound device and areas with the most contact in the abdominal phantom to detect bacteria that are above the probe and determine the number of pathogens. I want to find out. The experimental method was rubbed 20 times with the sterilized cotton swab for sterilization and then smeared on Lysogeny broth (LB) agar, put into the incubator and incubated for 48 hours, and the colony forming unit (CFU) count was measured. The bacterial distribution of probe handle and abdominal phantom was evaluated by evaluation. As a result, the CFU value is the lens was $3.0{\pm}0.87$, print button was $5.5{\pm}1.06$, freeze button was $8.0{\pm}4.95$, phantom was $20.0{\pm}2.78$, line was $23.5{\pm}2.50$, and probe handle was measured as $35.3{\pm}10.75$. In this study, it is expected that attention to infection control of equipment during practice during medical ultrasound practice can be highlighted and further contributed to the reduction of bacterial infection rate of ultrasound devices.

학교에서 의료용 초음파 실습 시 초음파 장치의 Freeze 및 Print Button, 프로브의 Lens, 손잡이, Line 부분 그리고 복부 Phantom에서 가장 접촉이 많은 부위를 임의로 선정하여 프로브에 상제하고 있는 세균을 검출하여 병원균의 수를 알아보고자 한다. 실험 방법으로는 실험 대상 위치에 균채집용 멸균된 면봉으로 검사 대상 부위를 20번 문지른 후 Lysogeny broth(LB) agar에 도말을 실시한 후 배양기에 넣어 48시간 동안 배양하고 colony forming unit (CFU) 수를 평가하여 프로브 손잡이, 복부 Phantom의 세균 분포정도를 알아보았다. 그 결과 CFU 값은 Lens는 $3.0{\pm}0.87$, Print button는 $5.5{\pm}1.06$, Freeze button은 $8.0{\pm}4.95$, Phantom은 $20.0{\pm}2.78$, Line은 $23.5{\pm}2.50$, 그리고 Probe handle의 값은 $35.3{\pm}10.75$로 측정되었다. 본 연구에서는 의료용 초음파 실습 시 실습 시 장비의 감염관리에 대한 주의를 부각시키고, 나아가서 초음파 장치의 세균 감염률 감소에 확실하게 기여 할 수 있을 것으로 기대된다.
