  • Patent number: 5722965
    Abstract: The low profile ostomy system includes an adhesively securable repositionable pouch that bonds to a body-side mounting wafer. The repositionable pouch is removable from the mounting wafer for repositioning if necessary. In a preferred embodiment of the invention, a resealable tape, which is in the form of a foam tape, is located on a face plate of the pouch and a releasable film, which is backed by a foam tape, is located on a body-side mounting wafer. The face plate of the pouch is formed with an extension tab that is accessible before and after the pouch has been secured to the body-side mounting wafer. The extension tab facilitates peeling of the face plate from the body-side mounting wafer during removal of the pouch from the mounting wafer. The foam tape on the body-side mounting wafer and the face plate inhibit formation of wrinkles or kinks at the engagement surfaces of the face plate and body-side mounting wafer when the pouch is removed from the body-side mounting wafer.

  • Patent number: 5709673
    Abstract: The ostomy pouch has a coupling or securement member formed as a washer-shaped wafer of adhesive material, preferably a hydrocolloid. The pouch is secured directly onto the abdominal wall with the adhesive wafer aligned with the stoma. Flushability of the pouch is enhanced by forming the pouch with converging side walls within an optimum angular range and a predetermined pouch width and pouch height. The pouch also has a predetermined wall thickness and the wafer is of predetermined thickness. Thus when the pouch is deposited in a water-saver toilet, bottom end first in a carrier sleeve, the pouch can flow in streamlined fashion through the passages of a toilet and any sewer pipe or septic line connected to the toilet. If the flush capacity of the toilet and the flow rate of water through the toilet and sewer line are increased, the ostomy pouch can be deposited in the toilet without a carrier sleeve.

  • Patent number: 5681063
    Abstract: The connector assembly for double tubing includes a pair of interengageable coupling members that engage when latches on the respective coupling members are aligned in a predetermined nonlatching position. Locking of the coupling members together is accomplished by rotating one of the coupling members with respect to the other coupling member to interengage the respective latches of each coupling member. A latch section of one of the coupling members extends transversely of the coupling member body and a latch section of the other coupling member extends longitudinally of the coupling member body. A locking notch in one of the latch sections receives the other latch section to place the coupling members in a locked position when one of the coupling members is rotated to engage the latches. Further rotation of the coupling members unlatches the respective latch members to permit separation of the coupling members upon imposition of oppositely directed forces on each of the coupling members.

  • Patent number: 5672163
    Abstract: The pouch is formed of first and second thin barrier film walls welded along the periphery to form a waste receptacle. One wall has an inlet defined by an attachment ring. The ring mounts the pouch on an adhesive faceplate adapted to adhere to the skin surrounding the stoma. A membrane, formed of material which is gas permeable but transmits little moisture and no liquid, is situated between the walls to separate the receptacle into an inlet chamber, where solids, liquid and most moisture are retained, and an outlet chamber into which gas and a small amount of vapor passes. A filter is provided to permit the gas to exit the outlet chamber. A first section of superabsorbent material isolates the filter from the outlet chamber. By absorbing any moisture in the gas before it contacts the filter, blockage of the filter is prevented.

  • Patent number: 5662628
    Abstract: A coupling, which may be an ostomy coupling but could be any kind of tube or pipe coupling, includes a first coupling member 10 and a second coupling member 30 which are mutually interengageable and which surround an orifice 70. The coupling also includes a resilient split ring 50 which encircles the two coupling members and has a handle member 51 which can be manipulated to cause the split ring to be deformed. This causes the radially-inwardly extending tabs 52 on the ring to be shifted between respective first positions in which the split ring is undeformed and the tabs lock the two coupling members together and respective second positions in which the split ring is deformed in such a way as to shift the tabs radially outwardly to positions where they permit separation of the two coupling members.The split ring is desirably made of a relatively rigid but springy plastics material, for example an acetal resin.

  • Patent number: 5643234
    Abstract: The ostomy bag includes a multi-stage filter system that provides contamination protection for a deodorizing filter in the system. The multi-stage filter system also includes protection elements that are impassable to semi-liquid waste material but permit passage of gaseous waste. The protection elements are located such that gaseous waste must pass through the protection elements before it passes through the deodorizing filter. In one embodiment of the invention, the protection elements include a fluid and gas-impermeable cover layer with fluid bypass ports. The fluid and gas-impermeable cover layer is followed by a barrier filter that restricts passage of semi-liquid waste material. The barrier filter is followed by a liquid-impermeable membrane that prevents passage of liquid. The liquid-impermeable membrane is followed by a moisture-absorbent pad that is adjacent the deodorizing filter.
