Abstract

A flow control and collection system includes a flow control device having a tubular member in which an inflatable balloon is positioned about the circumference of the interior side wall for closing the passageway to movement of matter and liquid when the balloon is expanded and allowing flow when the balloon is contracted against the side wall to which it is attached. The flow control device includes an adapter at the outer end of the tubular member having one or more interlocking features. A generally outwardly extending flange may be configured at the outer end of the tubular member. The flange may be configured with an inflatable membrane having an inflated position wherein at least a portion of the inflatable membrane extends generally outwardly from the flange.

Claims

1. A flow control device adapted for insertion into a body opening having an inner surface and an outer surface, the device comprising:

a tubular member having an inner circumference opposite an outer circumference, an inner end and an outer end interconnected by a passageway adapted for passing fluid or waste therethrough;

a flange extending outwardly from the tubular member proximate to the outer end, the flange having a width defined between a peripheral edge and the outer circumference of the tubular member; and

an inflatable membrane disposed on an inner surface of the flange and extending inwardly from the peripheral edge towards the outer circumference of the tubular member for a portion comprising less than the width of the flange, the inflatable membrane configured to be in contact with the outer surface of the body opening.

3. The flow control device of claim 1 further comprising an absorbent disposed on the inner surface of the flange for a portion separate from the portion occupied by the inflatable membrane.

5. The flow control device of claim 1 wherein the inner surface moves from the deflated to inflated position in a direction generally toward the inner end of the tubular member.

2. The flow control device of claim l wherein the inflatable membrane is inflatable when installed on the body.

4. The flow control device of claim 2 further comprising an inflation valve in communication with the inflatable membrane.

6. The flow control device of claim l wherein the flange comprises a generally convex profile.

7. A flow control device for human excretions comprising:

a tubular member having an inner circumference opposite an outer circumference, a passageway, and an inner end and an outer end configured to be disposed on opposite sides of an opening in a human body;

an inflatable balloon valve attached radially within the tubular member proximate to the inner end;

an inflatable membrane extending radially outward from an exterior surface of the tubular member proximate to the inner end;

a flange extending outwardly from the tubular member and terminating at an outer perimeter;

an inflation valve disposed on the flange proximate to the outer perimeter and fluidly connected to the inflatable membrane; and

an expandable seal extending towards the outer circumference of the tubular member from the outer perimeter of the flange and comprising a portion of an inner surface of the flange less than a distance between the outer circumference of the tubular member and the outer perimeter, Wherein the expandable seal is adapted to seat around the opening to seal the opening against leakage.

8. The flow control device of claim 7 wherein the expandable seal is inflatable when installed within the opening of the human body.

9. The flow control device of claim 7 further comprising an absorbent removably disposed on the inner surface of the flange and positioned between the tubular member and the expandable seal.

10. The flow control device of claim 7 wherein the expandable seal extends to a peripheral edge of the flange.

11. The flow control device of claim 7 wherein the expandable seal further comprises a flange contact surface and a skin contact surface, wherein the skin contact surface is step-shaped.
