[0031] Further, in one embodiment, see the attached Figure 1 As shown, one end of the perfusion pressure measuring bottle 61 is connected to the three-way joint 15 through the pressure-bearing joint 63 , and the other end of the perfusion pressure measuring bottle 61 is connected to the perfusion pressure measuring joint 22 through the pressure-transmitting joint 65 .

[0032] Further, in one embodiment, see the attached Figure 4 As shown, a sealing ring seat 67 is inserted into the threaded end 64, and the sealing ring seat 67 and the threaded end 64 are tightly fitted. An inflated air bag 69 mounted on the sealing ring seat 67 is placed in the cavity of the balloon bottle 62. A pressure plate 66 covers the threaded end 64 and is tightly abutted against the threaded end 64. A screw cap 68 is mounted on the pressure transmission joint 65, and the screw cap 68 is threadedly connected to the threaded end 64. The screw cap 68 locks the pressure transmission joint 65 (pressure plate 66) to the threaded end 64 of the balloon bottle 62. The pressure transmission joint 65 is electrically connected to the perfusion pressure measuring joint 22.

[0033] The outer wall of the sealing ring seat 67 is provided with a plurality of anti-dropping convex rings, and the airbag 69 is covered on the anti-dropping convex rings of the sealing ring seat 67. The balloon bottle 62, the pressure-receiving joint 63, and the threaded end 64 are integrated. The pressure-transmitting joint 65, the pressure plate 66, and the sealing ring seat 67 are integrated.

[0034] The perfusion pressure measuring bottle 61 detects the pressure of the perfusion water inlet pipeline, and the perfusion pressure measuring joint 22 (through the pressure sensor 26) is used to monitor the perfusion water outlet pressure of the peristaltic pump 31 (perfusion pump).

[0035] Further, in one embodiment, see the attached Figure 3 As shown, the outer diameter D2 of the sealing ring seat 67 is equal to or smaller than the inner diameter D4 of the threaded end 64, and the outer diameter D2 of the sealing ring seat 67 is tightly matched with the inner diameter D4 of the threaded end 64; the outer diameter D1 of the pressure plate 66 is larger than the outer diameter D2 of the sealing ring seat 6); the outer diameter D1 of the pressure plate 66 is smaller than the outer diameter D3 of the threaded end 64, and the outer diameter D1 of the pressure plate 66 is larger than the inner diameter D4 of the threaded end 64, and the pressure plate 66 is tightly set at the end of the threaded end 64.

[0036] Symmetrical clamping seats 32 are provided on either side of the peristaltic pump 31. These clamping seats 32 clamp the pipe 19 onto the peristaltic pump 31. Nuts 34 are mounted on the clamping seats 32, and an adjusting screw 33 is located below the clamping seats 32, matching the nut 34. Rotating the adjusting screw 33 adjusts the vertical displacement of the clamping seats 32. Indicator marks 35 are located on the outward side of the clamping seats 32. The adjusting screw 33 allows the clamping seats 32 to be raised or lowered to clamp pipes 19 of varying diameters. The indicator marks 35 indicate the positions of pipes 19 of varying diameters. The adjusting screw 33 also allows for fine-tuning of the clamped portion of the pipe 19.

[0037] The peristaltic pump 31 infuses water into the water outlet conduit (pipeline 19), and the water enters the endoscope 13 (flexible endoscope), and the endoscope 13 is inserted into the renal pelvis. The perfusion pressure bottle 61 detects the perfusion pressure on the endoscope 13, and the flow is controlled by the peristaltic pump 31. The perfusion pressure bottle 61 monitors and controls the perfusion pressure, and performs output pressure and flow control.

[0038] The perfusion pressure measuring bottle 61 detects the perfusion pressure on the endoscope 13, and the peristaltic pump 31 performs flow control. The perfusion pressure is monitored and controlled by the perfusion pressure measuring bottle 61, and the output pressure and flow control are performed.

[0039] The perfusion pressure measuring bottle 61 is used for water filling pressure measurement (perfusion water inlet pressure measurement). The pressure measuring port is on the pipe 19 of the water outlet conduit. The pipe 19 of the water outlet conduit is provided with a three-way joint 15. When the peristaltic pump 31 perfuses the water outlet conduit (pipe 19), one of the three-way joints 15 on the water outlet conduit (pipe 19) is connected to the perfusion pressure measuring bottle 61, and the other joint of the three-way joint 15 is connected to the endoscope 13 (flexible endoscope). When the endoscope 13 (flexible endoscope) is blocked or the pressure is too high, it can be sensed through the perfusion pressure measurement, and the peristaltic pump 31 will automatically adjust or shut down.

[0040] The perfusion pressure bottle 61 contains a balloon 69 (latex balloon) within the balloon 62. This balloon 69 must remain inflated. This balloon 69 measures the perfusion pressure by squeezing liquid after it enters the balloon 62. It also acts as a barrier, isolating the device from water. The balloon 69 within the balloon 62 converts hydraulic pressure into air pressure. The perfusion pressure bottle 61 provides a sterile, pressure-resistant flushing system, displaying real-time pressure readings. When the perfusion pressure exceeds the set pressure, the peristaltic pump 31 shuts down or slows down to maintain the set pressure.

By way of illustration, the accompanying drawings show specific embodiments that can implement the present invention. These embodiments are also referred to as "examples" in this article. In addition to those elements shown and described, these examples can also include other elements.
