Disposable urethral catheter assembly
First Claim
1. A fluid collector comprising a urethra catheter for delivering a quantity of liquid from a human body, and a flexible bag containing the catheter prior to catheter use, the bag including first barrier means defining at least a first chamber capable of containing a predetermined volume of liquid and a second chamber capable of containing the liquid delivered from the body in excess of the liquid deposited in the first chamber, the collector further including a cannula plug member for fully sealing the first chamber from the second chamber after the first chamber has been filled.

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.

- 1. A fluid collector comprising a urethra catheter for delivering a quantity of liquid from a human body, and a flexible bag containing the catheter prior to catheter use, the bag including first barrier means defining at least a first chamber capable of containing a predetermined volume of liquid and a second chamber capable of containing the liquid delivered from the body in excess of the liquid deposited in the first chamber, the collector further including a cannula plug member for fully sealing the first chamber from the second chamber after the first chamber has been filled.
- 11. A fluid collector comprising, in combination, a volume-calibrated, internally sterile bag adapted to contain a urethra catheter therein, the lower portion of the bag including heat sealed chevrons forming a fluid specimen reservoir of predetermined volume, a cannula plug contained within said specimen reservoir for insertion between the chevrons to seal the specimen reservoir from remaining portions of the bag, the bag further including a second set of heat sealed opposed chevrons near the top of the bag defining a channel through which the catheter is extended during catheterization and further defining, at least in part, a restricted chamber at the bag top for accepting a male penis.
- 12. A fluid collector comprising a urethra catheter and an elongated flexible container having, at its top, a stiffened resilient cuff normally biased into a closed position, a pair of seal lines defining a restricted top chamber at the bag top, an upper chamber housing the urethra catheter, a heat sealed restrictive opening defining the bottom of said upper chamber and the top of a lower chamber, and a cannula plug for closing the upper chamber from the lower chamber.
- 14. A fluid collector bag comprising, in combination, a flexible film defining two opposed bag sides, and first barrier means defining at least a first chamber capable of containing a predetermined volume of fluid and a second chamber capable of containing liquid in excess of the liquid deposited in the first chamber, the first barrier means also defining a restricted opening and plug means initially positioned in said first chamber cooperating with said restricted opening for selectively sealing the first chamber from the second chamber after the first chamber has been filled.
