Abstract

A male urinary drainage device composed of a thin resilient external catheter or sheath and an adhesive sealant pad for holding the sheath in place and for producing an effective seal to prevent urine backup and leakage. The pad is formed of compressible, deformable, water-resistant, and elastic sealant material and includes a ring portion adapted to seal about the penis at or directly behind the glans thereof and at least one integral strap portion projecting radially from the ring portion and intended to extend along the penile shaft. The strap portion functions primarily to provide sheath retention, whereas the ring portion coacts with the retained sheath and with the penis to serve primarily as a barrier against fluid backup.
