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.
