Referring to fig. 1 to 2, the urine receptacle according to the embodiment of the present invention includes a flexible urine drainage tube 10 and a tip 11, and the tip 11 is connected to an inlet end of the urine drainage tube 10 through a neck 12. The inner wall and the head end opening of the urinary catheter 10 can be coated or made of hydrophobic materials, so that the urinary catheter is not easy to scale and can be implanted into the urethra for a long time. The length of the urinary catheter 10 slightly exceeds the length of the male prostatic urethra or the female vagina, so that urine can flow out smoothly. The side wall of the neck 12 is provided with a plurality of openings 13, the end of the urinary catheter 10 is provided with an electromagnetic valve, and after the electromagnetic valve is opened, urine in the bladder can flow into the urinary catheter 10 through the openings 13 on the neck 12. Preferably, the plurality of openings 13 of the neck 12 are spaced circumferentially around the neck 12 to allow urine to flow rapidly into the urinary catheter 10 through the openings 13. The solenoid valve comprises a ferromagnetic valve seat 32 and a permanent magnet valve element 30 for closing off the inlet of the urinary catheter 10, the permanent magnet valve element 30 being located in the neck 12 and being movable in its axial direction, the valve seat 32 being located on the urinary catheter 10.
The outer side of the tube head 11 is provided with a pressure sensor, a chip and a micro battery are arranged in the tube head 11, the pressure sensor senses the hydraulic pressure of urine in the bladder, and the urine can represent the urine volume in the bladder after calibration. Furthermore, an external remote controller can be arranged, the chip and the external remote controller realize information transmission and remote control through radio communication, a display screen and an alarm are arranged on the remote controller, urine volume data in the bladder collected by the pressure sensor can be transmitted to the display screen of the remote controller to be displayed, and when the numerical value collected by the pressure sensor is greater than a set value, the pressure sensor sends a signal through the chip to enable the alarm in the remote controller to send out an alarm, so that a patient is prompted to urinate. The opening and closing of the urination device can be controlled by the remote controller.
As an alternative embodiment, the end of the pipe head 11 close to the neck 12 is provided with an electromagnetic element 31, the electromagnetic element 31 comprises an electromagnetic coil and an iron core located in the electromagnetic coil, and the chip, the micro battery, the pressure sensor and the electromagnetic element 31 are electrically connected. Correspondingly, the valve seat 32 in the urinary catheter 10 is an iron ring, which is located in the inner wall of the urinary catheter 10. When the pressure value in the bladder collected by the pressure sensor does not reach the set value, the permanent magnet valve core 30 and the valve seat 32 are mutually attracted, and the permanent magnet valve core 30 blocks the inlet of the urinary catheter 10, so that urine in the bladder cannot be discharged through the urinary catheter 10 at any time, a urine bag is not needed, and the expansion and contraction functions of the bladder of a patient can be exercised. When the value collected by the pressure sensor reaches the set value, the alarm in the remote controller gives an alarm, and the patient can press the start key on the remote controller after the patient is ready, so as to start the electromagnetic element 31. The chip controls the micro battery to output a positive electric pulse to the electromagnetic coil of the electromagnetic element 31, so as to generate a positive magnetic field, and the direction of the positive magnetic field of the electromagnetic element 31 is the same as the direction of the magnetic field of the permanent magnetic valve core 30, and is enhanced under the action of the iron core. The electromagnetic member 31 can generate stronger attraction force to pull the permanent magnetic valve core 30, which is originally attached to the magnetic valve seat 32, toward one end of the electromagnetic member 31, so that the entrance of the urinary catheter 10 is opened. After the pulse current is over, the permanent magnet valve core 30 is still attracted on the iron core 31 due to the residual magnetism of the iron core and the action of the permanent magnet valve core 30, and the opening state of the electromagnetic valve is kept, so that urine can continuously and smoothly flow out of the urinary catheter 10 through the neck tube 12. When urination is finished, a stop key on the remote controller is pressed, the chip controls the micro battery to output a reverse electric pulse to the electromagnetic coil of the electromagnetic part 31, so that a reverse magnetic field is generated, the permanent magnet valve core 30 is pushed to the magnetic valve seat 32 of the urination pipe 10 by the repulsive force of the electromagnetic part 31, the permanent magnet valve core 30 is attracted to the magnetic valve seat 32 again, and the electromagnetic valve closes the inlet of the urination pipe 10. For people with special diseases, the chip can be provided with a time-delay automatic closing electromagnetic valve or an automatic closing electromagnetic valve according to pressure.
As another alternative, the valve seat 32 in the urinary catheter 10 may be a solenoid valve seat that includes a solenoid coil, a chip, a micro battery, a pressure sensor, and an electrical connection to the solenoid valve seat. When the pressure value collected by the pressure sensor is larger than the set value, the alarm on the remote controller gives an alarm, and the patient can press the start key on the remote controller at the moment to open the electromagnetic valve. The chip controls the micro battery to input reverse current to the electromagnetic coil of the electromagnetic valve seat, the permanent magnetic valve core 30 is pushed away from the electromagnetic valve seat, so that the electromagnetic valve is opened, and urine can continuously flow out of the urinary catheter 10 through the neck 12. When the urine drainage is finished, the closing key is pressed, the chip controls the micro battery to stop supplying power to the electromagnetic coil of the electromagnetic valve seat, the electromagnetic force disappears, the permanent magnet valve core is attracted with the ferromagnetic valve seat under the action of the permanent magnetic force, and the electromagnetic valve is closed.
The outer side of the urinary catheter 10 is provided with N annular positioning air bags 20, each positioning air bag 20 is arranged at intervals along the axial direction of the urinary catheter 10, and the inner wall of the urinary catheter 10 is provided with N liquid through ports 14 respectively communicated to the positioning air bags 20. Each liquid through port 14 is provided with a hydraulic valve, and when a large pressure difference occurs at two ends of the hydraulic valve, the hydraulic valve is opened, so that liquid at two ends of the hydraulic valve can circulate. N is a positive integer greater than 1, preferably N is equal to 2, and two positioning air bags 20 are respectively arranged at the front end and the tail end of the urinary catheter 10. The positioning balloon 20 is inflated into abutment with the bladder orifice and the inside of the urethra, thereby securing the urinary catheter 10 in the urethra. Preferably, the outer diameter of the positioning balloon 20 closest to the tip 11 is larger than the outer diameter of the remaining positioning balloons 20. After the positioning air bag 20 closest to the tube head 11 is expanded, the function of fixing the urinary catheter 10 in the urethra is achieved, more importantly, the function of sealing the bladder opening is achieved, urine in the bladder is prevented from flowing out from the gap between the urinary catheter 10 and the urethra, and the situation of urine leakage is avoided.
