Claim 7
Dependent Claim
123 words
An ostomy irrigating device comprising: a truncated conical walled holder having a circular open top or apex, a circular bottom, and an integral circular flange extending toward the circular bottom and defining a groove between the flange and the internal wall of the conical holder, a flexible elongated hollow round-nosed nozzle, separable from the conical walled holded, having a cylindrical front portion with at least one liquid dispensing orifice and a rear portion having an outwardly tapered part in contact with the conical walled holder about an interior tapered surface area adjacent the apex, said nozzle front portion extending outwardly from the apex, and the tapered part of the nozzle having a flange adapted to nest in the groove in the conical holder.
Claim 8
Dependent Claim
31 words
An ostomy irrigating device according to claim 5 in which the flange has an internal cylindrical surface which contacts a nozzle cylindrical surface to the rear of the nozzle tapered surface.
Claim 9
Dependent Claim
26 words
An ostomy irrigating device according to claim 6 in which the nozzle is substantially thicker walled at its cylindrical surface which contacts the holder cylindrical surface.
Claim 10
Dependent Claim
101 words
An ostomy irrigating device comprising: a truncated conical walled holder having a circular open top or apex and a circular bottom, a flexible elongated hollow round-nosed nozzle, separable from the conical walled holder, having a cylindrical front portion with at least one liquid dispensing orifice and a rear portion having an outwardly tapered part in contact with the conical walled holder about an interior tapered surface area adjacent the apex, said nozzle front portion extending outwardly from the apex, said nozzle rear portion having an integral tubular extension projecting axially outwardly, and a rigid hose connector inserted into the tubular extension.
Claim 11
Dependent Claim
101 words
An ostomy irrigating device comprising: a truncated conical walled holder having a circular open top or apex and a circular bottom, a flexible elongated hollow round-nosed nozzle, separable from the conical walled holder, having a cylindrical front portion with at least one liquid dispensing orifice and a rear portion having an outwardly tapered part in contact with the conical walled holder about an interior tapered surface area adjacent the apex, said nozzle front portion extending outwardly from the apex, said nozzle rear portion having an integral tubular extension projecting axially outwardly, and a rigid hose connector inserted into the tubular extension.
Claim 12
Dependent Claim
99 words
An ostomy irrigating device comprising: a truncated conical walled holder having a circular open top or apex and a circular bottom, a flexible elongated hollow round-nosed nozzle, separable from the conical walled holder, having a cylindrical front portion with at least one liquid dispensing orifice and a rear portion having an outwardly tapered part in contact with the conical walled holder about an interior tapered surface area adjacent the apex, said nozzle front portion extending outwardly from the apex, and an elongated tubular retainer plug having a forward tapered portion inserted at least partly into the nozzle rear portion.
Claim 13
Dependent Claim
99 words
