Abstract
A disposable urethral catheter assembly includes a flexible bag in which are defined a number of chambers. In an upper chamber, a catheter is contained in a sterile environment. When the catheter is inserted into the urethra, the fluid flows into the bag and into a lower sample chamber, excess fluid being collected in the upper chamber. After catheter use, a cannula plug seals a first barrier between the upper and lower chamber and thus isolates the sample in the lower chamber. The upper chamber, its contents and the catheter are discarded, and the lower sample chamber and its contents are sent to a laboratory for analysis and culture.
