ABSTRACT:
A disposable urethral catheter assembly includes a flexible bag in which a number of chambers are defined by barriers. In an upper chamber, a catheter is contained in a sterile environment. When the catheter is inserted through the urethra into the bladder, the fluid flows into the bag through the upper chamber and into a lower sample chamber, excess fluid being collected in the upper chamber. After catheterization, a one-piece element which provides a sealable passageway through the first barrier between the upper and lower chamber can be readily closed by manipulation through the wall of the bag and thus isolate the sample in the lower chamber. The upper chamber, its contents and the catheter are separated from the sealed lower chamber and discarded. The lower sample chamber which provides a sterile environment for its contents can then be sent to a laboratory for analysis and culture.
