Abstract: A drainage system for body fluids comprising, a receptacle having a collection chamber for retaining the body fluids, a container having a supply chamber for retaining a bactericide, and a holding chamber. The system has a first one-way valve member permitting the passage of bactericide from the supply chamber into the holding chamber, and preventing passage of the bactericide from the holding chamber into the supply chamber. The system has a second one-way valve member for permitting passage of the bactericide from the holding chamber into the collection chamber, and for preventing passage of the contents from the collection chamber into the holding chamber.

Abstract: A system for aseptically removing urine from a primary drainage bag attached to a patient by conventional catheter means which includes a separate sterile disposable transfer bag. Rigid laterally extending spout interconnects the two bags when drainage is desired. The primary drainage bag is formed in the preferred embodiment with an outlet provided with self-closing flaps and slip valves which may be penetrated by the spout mounted on the transfer bag. Locking rib and groove means secure the spout in the outlet and a removable cap covers the outlet when the transfer bag is not attached. In a second form, the spout and valve means are on the primary drainage bag and transfer bag respectively.

Abstract: An improved method and apparatus for effecting mid-stream sampling of catheterized flow of liquid from a body cavity is effected through use of an improved coupling between sections of catheter tube means. The improved coupling includes a tubular cross-member that provides two pairs of oppositely extending tubular arms, a first pair of arms adapted to connect to the portions of the catheter tube means, and with a valve member constructed and arranged for selective reciprocal movement in the other pair of tubular arms and so as to permit usual drainage in one position or to provide, in said second position, means for effecting diversion of flow for effecting mid-stream sampling without separating portions of the catheter system that might permit contamination. In the second position, the constructions permit of effecting a backflow flushing of the body cavity, or application of medication, or an instrument, through the improved coupling into the body cavity.

Abstract: A urine drainage device which provides reliable and effective bladder training is disclosed for use with a catheter connectable to the bladder and communicating with a collection bag. The device comprises a valve for controlling the connection between the catheter and the collection bag. The valve includes a normally closed inlet which is opened when a predetermined bladder fluid pressure is reached. A pressure substantially below the opening pressure of the valve is capable of maintaining the inlet in an open condition.

Abstract: A urine drainage bag having an outlet tube provided with a hydrophilic coating on its inner wall surface and an antimicrobial substance such as iodine carried within a frangible capsule adapted to be received within the tube and said substance being absorbable by the coating when the capsule is ruptured. A method of treating a urine drainage bag outlet tube to prevent multiplication or growth of microorganisms utilizing a frangible carrier within the tube is taught.

Abstract: A suction canister system for serial collection of fluids comprises a plurality of canisters. Vacuum is provided to the interior of the canisters each of which includes a valve for terminating the vacuum in the canister responsive to the level of fluid therein. The fluid is allowed to travel to a serially arranged canister when the valve on one canister is closed.A fluid flow adapter suitable for use in a fluid collection container includes a first open tube with second and third open tubes attached thereto. The second and third tubes are in direct fluid communication with the first tube but they are not in direct fluid communication with each other. This arrangement allows the second and third tubes to serve as fluid inlet and fluid outlet openings for the collection container.
