Abstract:
A simple automatic opening and closing type of urination apparatus, comprising:a flexible tube having an inlet port and an outlet port;a plunger having a pushing portion at one end and a contact portion at the other end;a bearing table disposed below said pushing portion of said plunger for supporting said flexible tube;an elastic member for normally biasing said pushing portion of said plunger onto said flexible tube on said bearing table to squeeze said flexible tube between said pushing portion and said bearing table;an electromagnetic solenoid for selectively attracting and repulsing said contact portion of said plunger; andan actuator for selectively coupling said electromagnetic solenoid to a power source;wherein said inlet port of said flexible tube is connected through a catheter for connection to a urinary bladder and said outlet port of said flexible tube is connected through a conduit tube to a urine-collecting bag;wherein said electromagnetic solenoid is energized when a urine pressure in the urinary bladder reaches a given value, thereby retracting said pushing portion of said plunger to release said flexible tube from being squeezed.
