Abstract
A nozzle suitable for irrigating the rectal and/or bowel cavities, the nozzle comprises an elongate stem incorporating a channel extending there through; whereby fluid may flow, in use, through said channel; said stem incorporating a fluid inlet and one or more fluid outlets; and a first skirt protruding, when secured to said elongate stem, radially from said stem; said first skirt being inherently flexible; whereby said skirt is sufficiently flexible for insertion through the anus and to thereafter rest against the internal wall of the rectum; wherein said first skirt comprises an annular hub which is secured to said elongate stem.
Claims23
A nozzle suitable for irrigating the rectal and/or bowel cavities, the nozzle comprising:
- an elongate stem incorporating a channel extending there through;
- whereby fluid may flow, in use, through the channel;
- said elongate stem incorporating a fluid inlet and at least one fluid outlet;
- and a first skirt projecting, when secured to said elongate stem, radially from said elongate stem and being provided as the first radially projecting member below said at least one fluid outlet;
- said first skirt being inherently flexible;
- whereby said first skirt is sufficiently flexible for insertion through the anus and to thereafter rest against the internal wall of the rectum;
- wherein said first skirt comprises an annular hub;
- said elongate stem and said first skirt being formed as two separate components;
- wherein said elongate stem comprises an annular recess which corresponds to said annular hub;
- and wherein said elongate stem incorporates a tip which is tapered at its distal extremity and said annular hub has an inner diameter which is lower than the external diameter of the lower part of said tip;
- said annular hub being sufficiently flexible to flex radially to allow the tip to be pushed through said annular hub and for the annular hub to thereafter flex back into said annular recess to be retained thereby.
A method of assembling a nozzle suitable for irrigating the rectal and/or bowel cavities comprising the steps of:
- providing an elongate stem that incorporates an annular recess and a tip which is tapered at its distal extremity, said stem further incorporating a channel extending there through;
- whereby fluid may flow, in use, through said channel, and said stem incorporating a fluid inlet and one or more fluid outlets;
- selecting a first skirt with an annular hub that is sufficiently flexible;
- and
- securing said annular hub to said stem by pushing the tapered tip through the annular hub, causing the annular hub to flex radially, and allowing the annular hub to thereafter flex back into the annular recess to be retained thereby;
- wherein said first skirt projects radially and is the first radially projecting member of the nozzle below said fluid outlets.
