CLOSED DRAINAGE SYSTEM

Abstract

Studies were performed experimentally and clinically to confirm the significance of the closed drainage system.
The experiment indicated that contamination of drainage bag might lead to infection of the bladder. It seemed that a high degree of protection to the urinary tract, in the type having discharge tube, would be afforded by adding the drip chamber to the discharge tube of the drainage bag.
Clinical evaluation of our model of the closed drainage system was conducted. Risk of infection up to 7 days, 10 days and 15 days were 0%, 5% and 13%, respectively.
Some discussions were done on the closed drainage system.
