  • Patent number: 4487606
    Abstract: A suction canister assembly comprises an enclosed receptacle having a first opening for providing suction to the receptacle and a second opening for drawing fluids, including liquids and gases, into the receptacle during suction. A unitary shut-off valve/filter element is associated with the interior side of the first opening. This element is oriented within the receptacle so as to be contacted by liquid in the receptacle which rises therein. The element is porous and is adapted to filter particulate matter from gas passing therethrough. In addition, the valve/filter element is capable of developing sufficiently high surface tension under liquid contact to serve as a barrier against liquid passage therethrough at pressure differentials across the element when vacuum is applied on one side of the element. As a result, the element is adapted to terminate suction through the suction opening when liquid rises in the receptacle to completely cover the element.

  • Patent number: 4465479
    Abstract: A drip chamber splash guard comprising an annular member receivable within the upper end of the chamber. The guard has one periphery thereof engaged adjacent a centrally located drip sleeve depending below the vented top inwardly of the vents for maintenance of a free flow of air inwardly through the vents. The other periphery of the splash guard member engages adjacent the inner surface of the surrounding chamber outward of the vents. Limited air discharge openings are provided at spaced points about the guard whereby inwardly directed air flow is maintained through the splash guard itself while the filter vents are protected against gross or excessive splashing. In a preferred embodiment, the splash guard will be in the form of a truncated conical member with the air openings adjacent the chamber wall remote from the drip sleeve, the conical configuration, providing a tapered surface for a more effective deflecting of splash.

  • Patent number: 4443219
    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.

  • Patent number: 4417892
    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.

  • Patent number: 4305405
    Abstract: A urine meter bag for accurately measuring and storing urine passing from a patient including a meter for receiving the urine flow having a large measuring chamber and a smaller calibrated chamber into which the flow initially passes. Upon filling of the calibrated chamber, overflow passes into the large chamber. The meter rests in tandem against a flexible drainage bag and is in fluid communication therewith near the top so that the meter can be tipped and its contents emptied into the bag. A special support assembly pivoted on the bag hanging bracket includes slotted side arms which straddle the meter and receive pivot pins on the meter which facilitate support and emptying of the meter into the bag.
