Urinary incontinence automatic control system having multi-point alternate switching function, and in-vivo machine thereof

An intracorporeal apparatus for controlling urinary incontinence, configured to be completely implanted in a body, the intracorporeal apparatus comprising an intracorporeal microcontroller and urethral blockers, the intracorporeal microcontroller being configured to control the urethral blockers to block and unblock a urethra, wherein the intracorporeal apparatus comprises at least two urethral blockers configured to be located at different locations on the urethra, and the intracorporeal microcontroller is configured to control the at least two urethral blockers to block and unblock the urethra in turn;

• wherein the intracorporeal apparatus further comprises at least one pump, a solenoid valve set and a reservoir bag, and each of the urethral blockers comprises a C-shaped bag, the intracorporeal microcontroller being electrically connected with the at least one pump and the solenoid valve set, respectively, the reservoir bag being connected with the C-shaped bag through a connecting tube via the at least one pump and the solenoid valve set, and the intracorporeal microcontroller configured to control the at least one pump and the solenoid valve set so as to cause liquid to be filled into and released from the C-shaped bags of the urethral blockers in turn;
• wherein the solenoid valve set comprises a master solenoid valve and a plurality of urethral blocker solenoid valves corresponding to each of the urethral blockers respectively, wherein first ends of the plurality of urethral blocker solenoid valves are respectively connected with a liquid inlet and outlet port of the corresponding urethral blockers;
• second ends of the plurality of urethral blocker solenoid valves are both connected with a first end of the master solenoid valve;
• a second end of the master solenoid valve is connected with a liquid inlet and outlet port of the reservoir bag;
• a first end of the at least one pump is connected with the second ends of the plurality of urethral blocker solenoid valves;
• and a second end of the at least one pump is connected with the liquid inlet and outlet port of the reservoir bag;
• wherein the urethral blockers further comprise a support ring located on an outer side of the C-shaped bag, the support ring being configured to open by elastic deformation when a pressure in the support ring is above a threshold;
• wherein the support ring comprises a first segment, a second segment, a third segment and a fourth segment that are connected successively, wherein the second segment and the third segment form a C-shaped main body portion of the support ring;
• the first segment is bent from one end of the second segment in a direction opposite to a bending direction of the second segment;
• and the fourth segment is bent from one end of the third segment in a direction opposite to a bending direction of the third segment, wherein the first segment and the fourth segment first come close to each other from the end of the second segment and the end of the third segment, respectively, until contact with each other, and then go away from each other.
