逆行性感染ならびに院内感染防止用に考案した持続導尿装置

Abstract

1. A new urine-collecting device was manufactured and clinically tried with an idea of prevention of catheter-associated infection as well as nosocomial infection. 2. The device keeps a permeable bag containing chloramine T as desinfectant. The unne from the indwelling catheter dissolves chloramine T immediately after it enters the device and drops down to the bottom. 3. Nine patients known to have catheter-associated infection were chosen for the trial. Infecting microorganisms consisted of 10 strains of gram-negative rods and one gram-positive cocci. Urine samples from the new device showed negative cultures in 7 and decreased quantitative cultures in 3 as to gram-negative rods. Gram-positive cocci also disappeared. 4. This new urine-collecting device is inexpensive, easy and simple to use, and will contribute to prevention of catheter-associated retrograde urinary infection as well as nosocomial infection.
