Abstract

In the probe of a medical ultrasound device, three parts were selected randomly by the examiner and the bacteria in the probe were detected by the blood examiners. In addition, the degree of death of the pathogenic bacteria after each disinfection of the detected pathogens, disinfecting ethanol, and disinfecting tissue of the detected pathogens were analyzed quantitatively. The following was detected: S Aureus (32.3 %), Bacillus spp. (26.5 %), Micrococcus spp. (21.5 %), and CNS (20 %). With the conventional probe, S. aureus (26.2 %), a playback curve (24.2 %), and a micron (19.5 %), Micrococcus spp. (15.5 %), and CNS (14.6 %) were observed. In the fan probe, S. aureus (24.7 %), Enterococcus (24.7 %), Enterococcus (17.7 %), and CNS (13.8 %) were detected. The disinfection of the three pathogens detected revealed sterilization of most of the pathogens, and most cases contained at least 91.3 % of the total sterilizing effect (P>0.05). In addition, for the disinfection of Propolis extract and disinfecting tissue, the disinfection effect was lower than that of disinfecting ethanol, but the difference was not statistically significant (P>0.05). The results revealed bacteria on most of the ultrasound probes. Antiseptic disinfection of surgical instruments using an extract of propolis works with results similar to those of ethanol. A blood test along with disinfection can help prevent infection if an ultrasound probe is applied to food.

의료용 초음파 장치의 프로브에서 일반적으로 검사자와 피 검사자가 접촉이 가장 많은 부위 중 무작위로 3부분을 임의로 선정하여 프로브에 상제하고 있는 병원균을 검출하여 병원균의 종류와 균수를 알아보았다. 또한 검출된 병원균에 대하여 프로폴리스 추출액, 소독용 에탄올, 소독용 티슈를 이용하여 각 각 소독 후 병원균의 사멸정도를 정량적으로 알아보았다. 그 결과 선형 프로브에서는 S. aureus(32.3%), Bacillus spp.(26.1%), Micrococcus spp.(21.5%), CNS(20%)가 검출되었고, 볼록형 프로브에서는 S. aureus(26.2%), Strepto coccus(24.3%), Entero coccus(19.5%), Micrococcus spp.(15.5%), CNS(14.6%), 부채꼴 프로브에서는 S. aureus(24.1%). Micrococcus spp(24.1%), Entero coccus(20.7%), Strepto coccus(17.2%), CNS(13.8%)순으로 검출되었다. 검출된 병원균을 대상으로 소독을 위해 선정한 3가지 소독액을 이용하여 소독한 결과 소독용 에탄올의 경우 대부분의 병원균을 사멸시켰으며 최소 91.3 %에서 최대 100 %의 사멸효과로 가장 큰 소독 효과가 있는 것으로 분석되었다(P>0.05). 또한 프로폴리스 추출액과 소독용 티슈의 경우 모든 소독용 에탄올에 비해 소독효과는 낮았으나 소독효과에는 통계적으로 유의한 것으로 분석되었다(P>0.05). 실험결과를 보면 대부분의 초음파 프로브에서 다양한 병원균이 검출되었으며, 소독용 에탄올, 소독용 티슈의 소독효과가 있었으며 특히 프로폴리스 추출액을 이용한 소독도 병원균 사멸에 효과가 있는 것으로 분석되어 향 후 검사자와 피검사자의 접촉이 많은 초음파 프로브 소독 시 적용한다면 감염예방에 있어 도움이 될 것으로 사료된다.
