External male urinary catheter with garment

Claim 2

An external male urinary catheter assembly comprising a moderately thin, flexible, resilient durable tubular sheath dimensioned to be positioned in enclosing relation to a substantial portion of the penis, said sheath including a distal tubular member having a central aperture providing an open end, the proximal end of said sheath opposite to said distal end portion forming an annular flange, said catheter sheath having a pleated portion between said distal and proximal ends, at the proximal end said pleats having an inner diameter to encircle the penis without constricting the same and at the distal end said pleats having an inner diameter smaller than the inner diameter at the proximate end, and a resilience to snugly engage the tip of the penis without constricting the flow of urine therethrough; drainage tubing telescopically engaging said tubular member to communicate at the distal end with said tubular sheath through said aperture and extending to a connection element, said connection element communicating with a collection receptacle having means for attachment either to the ambulatory wearer at his calf or to the bedside of the bedridden wearer; and a supporting garment of the men's brief type, having elasticized leg openings and an elasticized waistband, said garment composed of an absorbent material and having an annular reinforcement on the front thereof complementary to said flange, and dimensioned to encircle the penis without constricting the same, said flanged end portion engaging said reinforcement and securely united thereto by fastening means continuously circumscribing said reinforcement and said flange respectively to provide a continuous connection therebetween without substantially constricting the penis.

Claim 3

An external male catheter assembly according to claim 1 wherein said collection receptacle is a hollow member having a normally-expanded cavity, the receptacle being a polyethylene bag capable of being compressed by bringing the sides together, a valve for said receptacle operable between open and closed positions to be open to permit collapse of said cavity from its normally-expanded condition to its compressed condition, and to close off said cavity when the bag is in its compressed condition, the bag being connected fluid-tight to said drainage tubing so that the tendency of the bag to return to its normal shape creates a negative pressure in its cavity and said drainage tubing.

Claim 4

A catheter assembly according to claim 1 wherein said pleats are accordion pleats which afford compacting of said sheath along its tubular axis for ease of application to the penis.

Claim 5

A catheter assembly according to claim 1 wherein a selected number of the pleats adjacent the proximal end have the same inner diameter to produce a generally cylindrical tubular interior in the sheath, and the remaining pleats toward the distal end have diminishing inner diameters to provide an interior diameter in the sheath which generally tapers toward said tubular connection element.

Claim 6

A catheter assembly according to claim 1 wherein said supporting garment comprises two side panels, a front panel and a rear panel, said front panel having said frontal opening therein in a position to register with the penis of the wearer, and said rear panel having padding and a waterproof lining between the padding and the panel in a position to register with the anal opening of the wearer.

Claim 7

A catheter assembly according to claim 1 wherein said fastening means comprises a layer of adhesive between said reinforcement and said flange to firmly interconnect the same.

Claim 8

A catheter assembly according to claim 6 wherein said adhesive layer is releasable to afford replacement of the catheter after use.

Claim 9

An external urinary catheter for use by male patients in assembly with drainage tubing extending to a collection receptacle adapted to be attached to an ambulatory wearer at his calf or to the bedside of the bedridden wearer, said catheter comprising a supporting garment of porous absorbent material having front and rear panels connected together to snugly encircle the trunk of the male patient, said garment having en elasticized waist band and elasticized leg openings to retain the garment in place, the front panel having a frontal opening and an annular reinforcement surrounding the frontal opening, having a diameter adapted to encircle the penis of the male patient without constricting the same, said catheter further comprising a moderately thin, flexible, resilient, durable tubular sheath, dimensioned to fit in enclosing relation to a substantial portion of the penis, the tubular sheath having a diameter and resilience snugly engaging the outer circumference of the penis without constricting the flow of urine through the same, said sheath having a flange portion at its proximal end engaging said annular reinforcement and securely united therewith continuously about the entire circumference of the flange portion and the annular reinforcement to provide a continuous connection without substantially constricting the penis, said sheath including at its distal end at a distance to be positioned beyond the tip of the penis, a tubular open end member telescopically connected to said drainage tubing, said sheath having circumferential pleats between said proximal and distal ends, the inner diameter of the pleats at the proximal end corresponding to the diameter of said frontal opening, and being smaller at the distal end to provide said snug engagement of the outer circumference of the penis adjacent its tip.

Claim 10

An external urinary catheter for use by male patients in assembly with drainage tubing extending to a collection receptacle adapted to be attached to an ambulatory wearer at his calf or to the bedside of the bedridden wearer, said catheter comprising a supporting garment of porous absorbent material having front and rear panels connected together to snugly encircle the trunk of the male patient, said garment having en elasticized waist band and elasticized leg openings to retain the garment in place, the front panel having a frontal opening and an annular reinforcement surrounding the frontal opening, having a diameter adapted to encircle the penis of the male patient without constricting the same, said catheter further comprising a moderately thin, flexible, resilient, durable tubular sheath, dimensioned to fit in enclosing relation to a substantial portion of the penis, the tubular sheath having a diameter and resilience snugly engaging the outer circumference of the penis without constricting the flow of urine through the same, said sheath having a flange portion at its proximal end engaging said annular reinforcement and securely united therewith continuously about the entire circumference of the flange portion and the annular reinforcement to provide a continuous connection without substantially constricting the penis, said sheath including at its distal end at a distance to be positioned beyond the tip of the penis, a tubular open end member telescopically connected to said drainage tubing, said sheath having circumferential pleats between said proximal and distal ends, the inner diameter of the pleats at the proximal end corresponding to the diameter of said frontal opening, and being smaller at the distal end to provide said snug engagement of the outer circumference of the penis adjacent its tip.

Claim 11

A catheter according to claim 8 wherein a first series of said pleats adjoining the proximal end of said sheath all have inner edges of the same diameter to define a generally cylindrical passage communicating with said frontal opening, and a second series of said pleats from said first series toward the distal end of said sheath having inner edges of decreasing diameter to define a tapering passage terminating in said open tubular end.

Claim 12

A catheter according to claim 9 including a conveying end portion between said second series of pleats and said open tubular end.

Claim 13

A catheter according to claim 9 wherein said pleats afford compaction of said sheath along its tubular axis to facilitate engagement of the penis within the inner diameter of said pleats.
