[0030] In this embodiment, the first pressure measuring mechanism is a first pressure sensor unit, which is arranged between the first pressure measuring tube 15 and the first joint assembly. The bladder pressure and urethra pressure of the human body are detected by the first pressure sensor unit, which has a simple structure and is easy to design.

[0031] In one embodiment, the first pressure sensor unit includes a bladder pressure sensor 10 and a urethral pressure sensor 11, the first connector assembly includes a first connector 2 and a second connector 3, the bladder pressure sensor 10 is connected to the first connector 2, the bladder pressure sensor 10 is connected to the first pressure measuring tube 15, the urethral pressure sensor is connected to the second connector 3, and the urethral pressure sensor 11 is connected to the first pressure measuring tube 15.

[0032] The bladder pressure sensor 10 and the urethra pressure sensor 11 are both liquid pressure sensors. The bladder pressure sensor 10 is connected between the first pressure measuring tube 15 and the first joint assembly. The physiological saline in the perfusion tube 1 can enter the first pressure measuring tube 15 through the bladder pressure sensor 10. Since the bladder pressure sensor 10 is connected to the first pressure measuring tube 15, and the first pressure measuring tube 15 is connected to the human bladder, the pressure measured by the bladder pressure sensor 10 is the human bladder pressure.

[0033] The urethral pressure sensor 11 is connected between the first pressure measuring tube 15 and the first joint assembly. Since the urethral pressure sensor 11 is connected to the first pressure measuring tube 15, when the first pressure measuring tube 15 is withdrawn from the human bladder, it will pass through the human urethra. At this time, the first pressure measuring tube 15 is connected to the human urethra. Therefore, the pressure measured by the urethral pressure sensor 11 at this time is the human urethral pressure.

[0034] In one embodiment, the urodynamic pressure measuring tube also includes a first transfer tube 13, the first pressure measuring tube 15 includes an inlet channel 24 and an outlet channel 25, one end of the first transfer tube 13 is connected to the bladder pressure sensor 10, and the other end of the first transfer tube 13 is connected to the inlet channel 24.

Since the urethra pressure sensor 11 is connected to the first pressure measuring tube 15, when the first pressure measuring tube 15 is withdrawn from the human bladder, it will pass through the human urethra. At this time, the interface connecting the first transfer tube 13 and the second transfer tube 14 of the three-way joint 26 is opened, so that the second transfer tube 14 is connected to the first transfer tube 13, and the first pressure measuring tube 15 is connected to the human urethra, so that the pressure measured by the urethra pressure sensor 11 is the human urethra pressure.

[0039] In one embodiment, the end of the first pressure measuring tube 15 away from the human body has an external interface 19, and the external interface 19 is used to be connected to the first urodynamic detector 20.

[0040] In one embodiment, the second pressure measuring mechanism includes a second pressure sensor unit, which is connected between the second pressure measuring tube 21 and the second joint assembly. The end of the second pressure measuring tube 21 away from the second pressure sensor unit is used to enter the abdominal cavity of the human body, and the second pressure sensor unit is used to detect the abdominal pressure of the human body.

[0041] The second pressure measuring mechanism is a second pressure sensor unit, which is disposed between the second pressure measuring tube 21 and the second joint assembly. The abdominal pressure of the human body is detected by the second pressure sensor unit, which has a simple structure and is easy to design.

[0042] In one embodiment, the second connector assembly includes a third connector 4 , and the second pressure sensor unit includes an abdominal pressure sensor 12 , wherein the abdominal pressure sensor 12 is connected to the third connector 4 , and the abdominal pressure sensor 12 is connected to the second pressure measuring tube 21 .

The physiological saline in the perfusion tube 1 can enter the second pressure measuring tube 21 through the abdominal pressure sensor 12. Since the abdominal pressure sensor 12 is connected to the second pressure measuring tube 21, and the second pressure measuring tube 21 is connected to the abdominal cavity of the human body, the pressure measured by the abdominal pressure sensor 12 is the abdominal pressure of the human body.

[0044] In one embodiment, the urodynamic pressure measuring tube further includes a third transfer tube 22 , one end of the third transfer tube 22 is connected to the abdominal pressure sensor 12 , and the other end of the third transfer tube 22 is connected to the second pressure measuring tube 21 .

[0045] The second pressure measuring tube 21 has the same structure as the first pressure measuring tube 15. A hydrophilic coating is provided on the outer circumference of the second pressure measuring tube 21 to facilitate the second pressure measuring tube 21 to enter the human body. The second pressure measuring tube 21 has a connector for connecting to the third adapter tube 22. The physiological saline in the perfusion tube 1 enters the human bladder via the third connector 4, the abdominal pressure sensor 12, the third adapter tube 22 and the second pressure measuring tube 21 in sequence.

[0046] The second pressure measuring tube 21 is also connected to a second urodynamic detector 23 .

[0047] In this embodiment, except for the three-way connector, the other two tubes are connected to the Luer connector.

[0048] In this embodiment, the first connector 2 and the bladder pressure sensor 10, the second connector 3 and the urethra pressure sensor 11, and the third connector 4 and the abdominal pressure sensor 12 are all connected via a silicone tube 5. Both ends of the silicone tube 5 are provided with Luer connectors for easy disassembly and assembly. The specifications of the silicone tube 5 can be replaced according to actual conditions to increase the fit with the infusion tube 1.

[0049] In this embodiment, the first joint 2 , the second joint 3 and the third joint 4 are all provided with a liquid-stop clamp 6 .

[0050] The working principle of the urodynamic pressure measuring tube of the utility model embodiment is as follows:

[0051] When testing a patient, firstly, the first pressure measuring tube 15 is inserted into the patient's bladder through the patient's urethra, the second transfer tube 14 is connected between the first transfer tube 13 and the urethral pressure sensor 11, the interface connecting the second transfer tube 14 and the first transfer tube 13 of the three-way joint 26 is closed, and the second pressure measuring tube 21 is inserted into the patient's abdominal cavity through the patient's anus, and then the perfusion tube 1 is used to inject physiological saline into the patient's bladder through the bladder pressure sensor 10 and the inlet channel 24 of the first pressure measuring tube 15, and the perfusion tube 1 is used to inject physiological saline into the patient's abdominal cavity through the abdominal pressure sensor 12 and the second pressure measuring tube 21. Saline is added to enable the bladder pressure sensor 10 to measure the bladder pressure. At the same time, the fluid in the patient's abdominal cavity will flow from the second pressure measuring tube 21 to the abdominal pressure sensor 12, and the abdominal pressure sensor 12 will measure the patient's abdominal pressure. After measuring the human bladder pressure, the first pressure measuring tube 15 is withdrawn from the human bladder. The first pressure measuring tube 15 will pass through the human urethra. At this time, the three-way joint 26 is opened to connect the second transfer tube 14 with the first transfer tube 13. Since the first pressure measuring tube 15 is connected to the human urethra, the pressure measured by the urethral pressure sensor 11 is the human urethral pressure.

[0052] According to the urodynamic pressure measuring tube of the embodiment of the utility model, the first pressure measuring mechanism can detect the bladder pressure and urethral pressure of the human body, and the second pressure measuring mechanism can detect the abdominal pressure of the human body. Compared with the prior art, the bladder pressure, urethral pressure and abdominal pressure of the human body can be detected simultaneously and intuitively, thereby improving the accuracy of the detection of the bladder pressure, urethral pressure and abdominal pressure of the human body.
