Abstract
Abstract A valve device particularly useful in combination with a urostomy bag for collecting and holding urine discharged by a patient. The term ''''urostomy'''' as used herein refers to various urinary diversion surgical procedures, such as ureterostomy and ileal bladder operations in which an artificial opening is created for discharge of urine from a patient who is not able to pass urine in the normal manner. In its preferred form, the valve device comprises a tube-like frustoconical section having one end sealingly surrounding the inlet for the liquid and the other end closed by a cover secured to the end at spaced points. The material of the cover and of the tube-like section is flexible so that liquid may pass between the spaced points of connection of the cover to the tube-like section, with the flexibility of the material operating as a flap valve to prevent backflow of liquid. It is contemplated that the cover be secured to the tube-like section at spaced points around the 360* circumference of the cover so as to present an outlet regardless of the posture of the patient.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
141 words
In combination with a urostomy bag having an inner wall secured along its edges to an outer wall to provide a fluid-tight container, apparatus of the character described comprising a retaining member having an opening therein, means for holding the retaining member in place on the body of a patient, said inner wall having an orifice therein surrounding the opening in the retaining member with the edges of said orifice being sealed to a face of the retaining member, a frustoconical member of flexible material having one end surrounding the orifice in sealing relationship thereto, a flexible cover member covering the other end of the frustoconical member, said cover member being sealed to said other end of the frustoconical member at spaced points to provide one-way fluid passages between said points for flow of fluid from said inlet into said container.
Claim 2
Dependent Claim
141 words
