One end of the urinary catheter 4 is suitable for being inserted into the human bladder to achieve indwelling catheterization. The drainage pipeline 1 comprises: an introduction tube 1a, a urine sampling point 1b and a flow stop unit 1c. A silica gel urine sampling point 1b is provided on the side of one end of the introduction tube 1a. A collector needle can be inserted to extract fresh urine for urine component analysis.

When the switch of the main passage 1cb is blocked or fails, the control switch of the bypass passage 1cc can be turned on to conduct the urination passage and improve safety. The prior art solution has only one conduction passage. The switch of the main passage 1cb is the stop switch 1cd, which can realize the opening or closing of the passage by external control (such as motor, air pump, electromagnet), and can be automatically opened according to pre-designed rules to reduce manual participation. The bypass passage 1cc is the safety switch 1ca, which is a manually controlled switch and is equipped with an identification indicator to supplement the sudden failure of the main passage 1cb and improve safety. The RFID electronic tag 1ce of the stop unit 1c has a unique serial code and can burn relevant information to record and count the use of the drainage pipeline 1 and trace the later treatment information. The RFID electronic tag 1ce can burn the validity period of the drainage pipeline 1 and record the start time of use to control the validity period of use. By detecting the signal fed back by the electronic tag 1ce, it can be identified whether the drainage pipeline 1 is installed in place;

[0063] The urine bag 3 is hung on the measuring hook 2d with a weighing function, and the weight of urine flowing into the urine bag 3 is measured in real time. The corresponding urine volume is calculated by the urine density. After the urine bag 3 is full of urine, the urine in the urine bag 3 is discharged through the discharge switch 3a, and the urine bag 3 can be used repeatedly. The urine bag 3 is provided with a scale, and the urine volume can be directly observed through the bag body.

[0064] According to the urine drainage control and urine volume metering system of the present invention, Figure 1 , 3As shown in , 4, the system includes: a liquid flow controller 2, the liquid flow controller 2 is connected to the drainage pipeline 1, and is specifically used to control and adjust the amount of urine flowing through the drainage pipeline 1 and to measure and display the amount of urine flowing out of the drainage pipeline 1; at the same time, the liquid flow controller 2 is connected to the sensor signal in the drainage pipeline 1 to monitor the pressure information and temperature information of urine flowing through the drainage pipeline 1;

[0065] The liquid flow controller 2 includes a urine metering unit, a urination control unit, a urination control unit, a display setting unit and an electronic information recognition unit;

[0066] The urine metering unit includes: a weight sensor, a processing circuit, an operation processor and a storage unit. When in use, the urine storage bag 3 is hung on the metering hook 2d of the weight sensor with a weighing function. When the urine weight changes, the weight sensor will sense the change. After calculation by the operation processor, the change in urine weight is obtained, which is divided by the urine density to convert the urine volume, and the obtained data information is stored in the storage unit. Urine volume measurement is divided into two modes. First, the urination passage is opened, and the growth of urine volume can be continuously measured to reflect the speed of urine production in the human body. Second, the urination passage is controlled by a switch, which controls the urination passage to open and urinate in combination with the bladder pressure. The urine storage capacity of the bladder can be reflected by the single urination volume.

[0067] The real-time data monitoring unit includes: a temperature sensor 1cg, a pressure sensor 1cf and an acquisition processing circuit; the unit can collect the real-time pressure of the drainage pipeline 1, the temperature sensor 1cg is used to monitor the temperature of urine, and the pressure sensor 1cf is used to observe whether the bladder is in a safe pressure range, the compliance of the bladder and other information, and the temperature sensor is used to determine whether an infection occurs;

[0068] The urination control unit includes: a controller, a driving device (such as a motor, an electromagnet, an air pump, etc.) and a transmission structure. After setting the urination triggering conditions, such as setting the upper pressure limit value under the condition that the drainage pipeline 1 is closed, the controller sends a control signal to the driving device, and the driving device drives the transmission structure to move after receiving the control signal, and the transmission structure turns on the switch of the drainage pipeline 1, thereby protecting the bladder from being properly filled and under a certain pressure. In addition to setting the pressure value, a certain time interval can be set or the button 2c can be directly pressed to turn on the drainage pipeline 1 for urination. One end of the floating clutch structure 2f is connected to the transmission shaft of the transmission structure, and the other end of the floating clutch structure 2f is connected to the stop switch 1cd. When the drainage pipeline 1 is connected to the liquid flow controller 2, the transmission shaft (multi-tooth structure) is not completely aligned with the stop switch 1cd (groove), and the transmission shaft is pressed into the liquid flow controller 2 by the stop switch 1cd. The transmission shaft cannot bring the stop switch 1cd to move. When the transmission shaft rotates, the transmission shaft and the stop switch 1cd rotate relative to each other, and the convex part (multi-tooth structure) of the transmission shaft is gradually aligned with the groove, the transmission shaft pops up and falls into the groove of the stop switch 1cd, the transmission part completes the meshing, and the transmission shaft can drive the stop switch 1cd to move;

[0069] The display setting unit includes: the display screen 2b, the button 2c and the processing circuit. The display screen 2b and the button 2c are connected to the processing circuit and can set some parameters or display some measurement data (such as urine volume, bladder pressure, battery power) to interact with the user;

[0070] The electronic information identification unit can identify the drainage tube 1 with an RFID electronic tag 1ce that is used with it. The RFID electronic tag 1ce has a unique serial code and can burn relevant information to record and count the usage of the drainage tube 1 and trace subsequent treatment information. The RFID electronic tag 1ce can burn the validity period of the drainage tube 1 and record the start time of use to control the validity period of use. By detecting the signal fed back by the electronic tag 1ce, it can be identified whether the drainage tube 1 is installed in place.

[0071] To summarize, with the aid of the above-mentioned technical solutions of the present invention, the present application solves the problems of inconvenient and inaccurate manual recording of urine volume, bladder atrophy and urinary tract infection caused by long-term open catheterization, and laborious and inability to monitor bladder pressure in real time during the care of patients with indwelling catheters, so as to improve the effectiveness and safety of nursing care and reduce the workload of nursing care.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
