Abstract
Abstract A leakage-absorbing device to supplement a urostomy bag and absorb leakage across its seal flange, is readily put in place against the skin, inserted between the lower part of the flange and the bag; and is easily removed and replaced without removing the urostomy bag. It includes a pad whose lower portion is contained within a water-tight flexible pouch-like covering and whose upper yoke portion has a skin-facing side presented for absorption against the lower part of the base flange and the patient's skin. The device is supported by adhering to the skin immediately below the absorbent portion so presented.
