Urination control device

A urination control device comprising:

• a conduit configured to be inserted into a urethra;
• an upstream restraint member located in said conduit and having a through hole;
• a control member located downstream with respect to a flow of urine from a bladder, of said upstream restraint member in said conduit;
• and
• a downstream restraint member located downstream with respect to the flow of urine from the bladder, of said control member in said conduit,
• wherein said upstream restraint member is provided with a magnet and said control member is made of a magnetic material so that said upstream restraint member and said control member attract each other by means of magnetic force from said magnet,
• wherein said control member is adapted to be brought into contact with or part from said upstream restraint member responsive to an attracted force due to the magnetic force and a fluid pressure on an upstream side with respect to the flow of urine from the bladder, of said control member, and
• wherein said control member and said magnet are adapted that said control member parts from an opening portion of said through hole in said upstream restraint member and is brought into contact with said downstream restraint member to allow passage of a fluid through said through hole so as to open said conduit when the fluid pressure on the upstream side with respect to the flow of urine from the bladder, of said control member becomes no less than a first value that is determined by at least said attracted force, and that said control member is brought into contact with said opening portion to block passage of the fluid through said through hole so as to close said conduit when said fluid pressure becomes no more than a second value that is less than said first value.
