CLAIMS

1. A waste management appliance comprising:

a tubular body having proximal and distal ends;

a balloon coupled to the tubular body in the vicinity of the proximal end thereof; an inflation lumen opening at a proximal end to the interior of said balloon and extending distally from the balloon towards the distal end of the tubular body, and

a valve assembly fluidly coupled to the inflation lumen, the valve assembly comprising a valve body having first and second valve chambers in fluid communication with said inflation lumen, a coupling for connecting the lumen to a source of fluid being provided in said first chamber, and a pressure relief valve being provided in said second chamber;

the arrangement being such that the insertion of fluid into said lumen via said coupling from a source of fluid inflates said balloon until the balloon and lumen contain a predetermined quantity of fluid, whereupon continued insertion of fluid causes said pressure relief valve to operate and fluid to leak from the lumen via said valve instead of further inflating said balloon.

2. A waste management appliance, comprising:

a tubular body having a proximal end and a distal end;

a cowl fastened to said tubular body at a first circumferential location in the vicinity of said proximal end, said cowl extending distally outside of said tubular body to a second circumferential location spaced distally from said first circumferential location, said cowl being fastened to said tubular body at said second circumferential location at a plurality of spaced positions around the circumference of said tubular body;

an inflatable balloon provided within said cowl; and

an inflation lumen having a proximal end opening to the interior of said balloon and extending distally towards the distal end of said tubular body;

wherein the cowl can be separated from said tubular body at a plurality of circumferential regions where the cowl is not fastened to the tubular body to form a plurality of pockets between the cowl and the uninflated balloon into any of which a finger can be inserted for the purpose of guiding the balloon into a subject, and

the balloon can be inflated to a desired extent within the cowl by injecting a predetermined amount of fluid into said balloon via said lumen, the cowl functioning in the event of an attempt to inject more than said predetermined amount of fluid into said balloon to restrain inflation of said balloon beyond said desired extent.

3. A waste management appliance according to Claim 2, further comprising:

a valve assembly fluidly coupled to the inflation lumen, the valve assembly comprising a valve body having first and second valve chambers in fluid communication with said inflation lumen, a coupling for connecting the lumen to a source of fluid being provided in said first chamber, and a pressure relief valve being provided in said second chamber;

the arrangement being such that the insertion of fluid into said lumen via said coupling from a source of fluid inflates said balloon until the balloon and lumen contain a predetermined quantity of fluid, whereupon continued insertion of fluid causes said pressure relief valve to operate and fluid to leak from the lumen via said valve instead of further inflating said balloon.

4. A waste management appliance according to Claim 1 or 3, wherein said pressure relief valve comprises a valve member biased to prevent the flow of fluid from said lumen.

5. A waste management appliance according to Claim 4, wherein said valve member is biased by a resilient biasing means, for example a spring.

6. A waste management appliance according to Claim 4 or 5, wherein the valve member is biased by a biasing force in the region of 5 to 35 kPa, more preferably in the region of 15 to 20 kPa, and most preferably in the region of 16 to 18 kPa.

7. An appliance according to any of Claims 1 to 6, wherein said tubular body includes an externally accessible irrigation lumen that opens proximate said proximal end of said tubular body.

8. An appliance according to any of Claims 1 to 7, further comprising a waste collection receptacle.

9. An appliance according to Claim 8, further comprising means for detachably mounting said receptacle to said distal end of said tubular body.

10. An appliance according to Claim 9, wherein said receptacle mounting means comprises a plate with an opening, and means for attaching said distal end of said

tubular body to said plate, in alignment with said plate opening.

11. An appliance according to any preceding claim, wherein at least part of said waste management appliance is provided with a lubricious coating.

12. An appliance according to Claim 11 , wherein an internal surface of said tubular body and an external surface of said cowl includes a lubricious coating.

13. An appliance according to Claim 11 or 12, wherein said lubricious coating comprises parylene.
