Abstract
Since a great many microorganisms (103) were detected on the hands of nurses who used disinfectants for hygienic washing, we developed a 30-second handwashing-warning chime (scrub timer) to aid in the progreesive reduction of resident skin bacteria by disinfection. Setting the scrub timer on the dispenser of the disinfectant (povidone iodine), enables a sound to be emitted when the handwashing dispenser is pushed.
In the Plastic Surgery Department, the nurses can maintain constant contact with disinfectants for 30 seconds using the scrub timer, which serves to decrease the amount of resident hand bacteria (102) following disinfectant use more so than if the scrub timer was not used.
Using the scrub timer was concluded to be effective for handwashing with disinfectants.
