Abstract

A simple automatic opening and closing type of urination apparatus (10) comprises a flexible tube (110), a plunger (120), a bearing table (130), an elastic member (140), an electromagnetic solenoid (150), and an actuator (160). The flexible tube (110) has an inlet port (111) and an outlet port (112). The plunger (120) has a pushing portion (121) at one end and a contact portion (122) at the other end. The bearing table (130) is disposed below the pushing portion (121) of the plunger (120) for supporting the flexible tube (110). The elastic member (140) normally biases the pushing portion (121) of the plunger (120) onto the flexible tube (110) on the bearing table (130) to squeeze the flexible tube (110) between the pushing portion (121) and the bearing table (130). The electromagnetic solenoid (150) selectively attracts and repulses the contact portion (122) of the plunger (120). The actuator (160) selectively couples the electromagnetic solenoid (150) to a power source (170). The inlet port (111) of the flexible tube (110) is connected through a catheter (11) to a urinary bladder (12) and the outlet port (112) of the flexible tube (110) is connected through a conduit tube (13) to a urine-collecting bag (14). The electromagnetic solenoid (150) is energized when a urine pressure in the urinary bladder (12) reaches a given value, thereby retracting the pushing portion (121) of the plunger (120) to release the flexible tube (110) from being squeezed.
