Abstract: A drainable ostomy pouch has an outlet. Reinforcing members at the outlet are deformable by application of manual pressure at their ends to distend the outlet. The lateral edges of the reinforcing members may be offset, which encourages the reinforcing members to consistently bend away from each other. A peelable distributed mechanical engagement fastener secures the outlet in a folded condition. The fastener parts are hook-hook type plastic extrusions, and provide a snap-engagement. A security flap is foldable under the outlet when in its folded condition. The outlet is released in two stages.

The resealable tape and the releasable film coupling arrangement permit repeated removal of the pouch from the body-side mounting wafer and repeated resecurement of the pouch to the mounting wafer. The pouch can thus be repositioned relative to the mounting wafer even after the pouch has been worn for a day.

Abstract: A flange for a medical collecting bag having an aperture allowing bodily fluids or exudates to enter the bag. The flange has an inner rim delimiting the aperture therein, and a central area encircling the aperture, which area has a predetermined weakening line pattern. The force needed for removing the bag flange from the skin or a body side member is smaller than the force needed for breaking the weakening lines which enables a simple gradual enlargement of the aperture of an ostomy device for adaptation of the aperture to the size of the stoma or for adaptation of the aperture to the size of a wound, as well as a complete removal of the bag flange when substituting the bag.

Abstract: An ostomy pouch for both one and two-piece ostomy appliances having an integral closure at the bottom of the pouch to allow the pouch to be emptied and re-sealed without the use of a separate closure. The integral closure has mating parts that are locked together and provides the ostomy appliance with a leak-proof, odor-proof seal when in a closed, sealed, and locked position. A slider, when the appliance is closed, can be moved along the integral closure, thereby separating the mated male and female parts to provide an opening through which the stored contents within the ostomy pouch can be emptied. After the stored contents have been emptied, the slider can reseal the pouch by rejoining the male and female parts. The integral closure is manufactured from material that is different and more rigid than the material used to manufacture the ostomy pouch.

Abstract: A feces control device includes a tubular member in which an inflatable balloon is positioned on one interior sidewall for closing the passageway to movement of feces when the balloon is expanded and allowing flow when the balloon is contracted against the sidewall to which it is attached. A second balloon on the inner end of the tubular member when inflated presses against the inner end of an umbrella mounted on the inner end of the tubular member thereby expanding the umbrella to a radially outwardly and forwardly extending sealing position in the stoma or rectum. When the umbrella balloon is deflated, the umbrella memory causes it to collapse to a position coaxial with the tubular member. Inflation passageways in the sidewall of the tubular member may include tube portions for inflating the balloons or removing the device from the rectum.

A plurality of tabs, arranged, e.g., symetrically, on the limbs of the locking ring can be withdrawn generally radially outwardly by movement of the locking ring to permit separation of the two coupling members. The movement of the locking ring which causes withdrawal of the tabs may be a vertically upward movement of the ring, or a vertically downward movement. The movement of the locking ring which causes withdrawal of the tabs alternatively may be a deformation of the ring in opposed horizontal directions. Preferably, however, the movement of the locking ring which causes a withdrawal of the tabs is a rotational movement relative to the second coupling member.
