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 waste collection bag has a sealed body with at least one opening and a flow control device adapter at the opening having one or more counterpoising interlocking features to removably lock the adapters together and passes waste material and liquid through the flow control device into the waste collection bag.

Claims

1. A flow control and collection system for human excretions comprising:

a flow control device comprising;

a) a tubular member having an inner end and an outer end interconnected by a passageway, and a wafer extending radially from and integral with the outer end, the tubular member being adapted for insertion into a body opening;

b) a device adapter having a substantially planar portion positioned adjacent to the integral wafer, and one or more interlocking features, wherein the interlocking features comprise a plurality of radially spaced keyways extending through the substantially planar portion of the device adapter;

a collection bag comprising;

a) a sealed body having at least one opening;

b) a bag adapter at the opening having a substantially planar portion positioned adjacent to the device adapter, and one or more counterpoising interlocking features, wherein the counterpoising interlocking features comprise a plurality of radially spaced keys;

c) wherein the interlocking features on the device adapter and counterpoising interlocking features on the bag adapter are connected when the plurality of radially spaced keys are joined with the plurality of radially spaced keyways to removably lock the flow control device and collection bag; and

a collection bag cap selectively sealing the at least one opening of the collection bag, wherein the collection bag cap has a plurality of radially spaced keyways arranged in a same configuration as the plurality of radially spaced keyways of the device adapter.

2. The system of claim 1 wherein the flow control device further comprises an inflatable balloon valve attached within the passageway for selectively allowing passage of matter and/or fluids, the inflatable balloon having a sealing surface that expands radially inward away from a sidewall surface of the passageway to seal together at a center of the passageway.

3. The system of claim 1 wherein the flow control device further comprises an expandable membrane on the outside of the inner end of the tubular member for selectively securing the control device in the body opening.

4. The system of claim 3 wherein the expandable membrane further comprises a wire frame having a collapsed position for inserting the inner end of the tubular member into the body opening and a pre-collapsed position for supporting the tubular member when the expendable membrane is inflated.

5. The system of claim 1 wherein the device adapter comprises an inner surface adjacent the outer end of the tubular member having a concave shape to prevent compression of tissue around the body opening.

6. The system of claim 1 wherein the collection bag cap is connected to the collection bag via a tether.

7. The system of claim 1 wherein the flow control device further comprises a device cap operably connectable to the device adapter to selectively seal the passageway of the flow control device proximate to the outer end of the tubular member, wherein the device cap has a plurality of radially spaced keys arranged in the same configuration as the plurality of radially spaced keys of the bag adapter of the collection bag.

8. A flow control and collection system for human excretions comprising:

a flow control device comprising;

a) a tubular member having an inner end and an outer end interconnected by a passageway, and a wafer extending radially from and integral with the outer end, the tubular member being adapted for insertion into a body opening;

b) a device adapter at the outer end of the tubular member having a substantially planar portion surrounding the passageway, wherein the substantially planar portion has one or more interlocking features comprising a plurality of radially spaced keyways;

a collection bag comprising;

a) a sealed body having at least one opening;

b) a bag adapter at the opening having a substantially planar portion and one or more counterpoising interlocking features comprising a plurality of radially spaced keys on the substantially planar portion of the bag adapter;

wherein the substantially planar portion of the device adapter is positioned adjacent both the integral wafer and the substantially planar portion of the bag adapter;

wherein the flow control device and collection bag are configurable between a connected and a disconnected position;

a collection bag cap selectively sealing the at least one opening of the sealed body of the collection bag, wherein the collection bag cap has counterpoising interlocking features comprising a plurality of radially spaced keyways;

wherein the plurality of radially spaced keys on the collection bag adapter is configured to independently attach directly to the plurality of radially spaced keyways on both the device adapter and the collection bag cap.

9. The system of claim 8 wherein the plurality of radially spaced keyways of the collection bag cap is arranged in a same configuration as the plurality of radially spaced keyways of the device adapter.

10. The system of claim 8 wherein the plurality of radially spaced keys are integrally formed with the substantially planar portion of the bag adapter.

11. A flow control and collection system for human excretions comprising:

a flow control device comprising;

a) a tubular member having a inner end and an outer end interconnected by a passageway and adapted for insertion into a body opening, and a wafer extending radially from and integral with the outer end of the tubular member;

b) an expandable membrane extending outwardly from an exterior of the tubular member proximate to the inner end of the tubular member;

c) a device adapter at the outer end of the tubular member having a substantially planar portion external to the passageway with one or more interlocking features, wherein the interlocking features comprise a plurality of radially spaced female contacts;

a collection bag comprising;

a) a sealed body having at least one opening;

b) a bag adapter having a substantially planar flange around the opening, the substantially planar flange having one or more counterpoising interlocking features, wherein the counterpoising interlocking features comprise a plurality of radially spaced male contacts contoured to the radially spaced female contacts;

a collection bag cap having a plurality of radially spaced female contacts contoured to the radially spaced male contacts of the collection bag;

wherein the substantially planar portion of the device adapter is positioned adjacent both the integral wafer and the substantially planar flange of the bag adapter;

wherein the plurality of radially spaced female contacts of the collection bag cap, the plurality of radially spaced female contacts of the device adapter, and the plurality of radially spaced male contacts of the collection bag are arranged in a same configuration; and

wherein the flow control device and collection bag is configurable between a connected and a disconnected position wherein the interlocking and counterpoising interlocking features connect together between the connected and disconnected positions.
