For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] A water-filled pressure measuring catheter includes a connecting tube 1, a branch tube 2 that is fixedly connected to the left side of the outer surface of the connecting tube 1, a sealing sleeve 3 that is fitted through the upper part of the outer surface of the branch tube 2, an airbag assembly 4 that is fixedly connected to the upper end of the connecting tube 1, and several catheters 5 that are fixedly connected to the lower end of the connecting tube 1. Each of the several catheters 5 has a rubber protective sleeve 6 fitted through the lower part of its outer surface.

[0026] In this embodiment, the connecting pipe 1 includes a pipe body 11, with a first screw groove 12 at the upper end of the pipe body 11. A connecting screw tube 13 is threaded through the inner wall of the first screw groove 12. A fixing ring 14 is fixedly connected to the middle of the outer surface of the connecting screw tube 13. A sealing ring 15 is sleeved on the upper part of the outer surface of the connecting screw tube 13. The pipe body 11 is fixedly connected to several conduits 5. The upper end of the sealing ring 15 is in contact with the lower end of the sleeve 43.

[0027] The above scheme involves threading the lower part of the outer surface of the connecting screw tube 13 into the first screw groove 12 to connect the connecting screw tube 13 to the tube body 11. The insertion tube 45 on the airbag assembly 4 is threaded into the inner wall of the connecting screw tube 13, and the second screw groove 46 is threaded onto the outer surface of the connecting screw tube 13 to facilitate the connection with the connecting tube 1 and the airbag assembly 4. The tube body 11 and the airbag assembly 4 are connected together through the connecting screw tube 13, and the connection between the connecting screw tube 13 and the tube body 11 is easy to disassemble and replace. The contact between the upper end of the sealing ring 15 and the lower end of the sleeve 43 can strengthen the connection between the airbag assembly 4 and the connecting tube 1 and improve stability.

[0028] In this embodiment, the airbag assembly 4 includes an airbag body 41. An air tube 42 is fixedly connected to the upper end of the airbag body 41, and a sleeve 43 is fixedly connected to the lower end of the airbag body 41. A limiting screw 44 is inserted into the lower right side of the outer surface of the sleeve 43. An insertion tube 45 is fixedly connected to the lower end of the airbag body 41, and the insertion tube 45 is located inside the sleeve 43. A second screw groove 46 is opened in the inner frame wall of the sleeve 43. The sleeve 43 is sleeved with the connecting screw tube 13. The limiting screw 44 passes through the sleeve 43 and contacts the connecting screw tube 13. The insertion tube 45 is inserted into the inner wall of the connecting screw tube 13.

[0029] The above solution involves threading the second screw groove 46 of the inner frame of the sleeve 43 to the connecting screw tube 13, and then using the limiting screw 44 to pass through the sleeve 43 and contact the connecting screw tube 13. This fixes the connection between the airbag assembly 4 and the connecting tube 1, and makes the connection between the airbag assembly 4 and the connecting tube 1 easy to install, remove, and replace.

[0030] It should be noted that this utility model is a water-filled pressure measuring conduit. During use, to protect the conduit, rubber protective sleeves 6 are fitted onto the lower part of the outer surface of several conduits 5. The rubber protective sleeves 6 have good flexibility and elasticity, allowing them to fit tightly against the outer surface of the conduits 5. In actual use, the conduit may bend or kink due to various external forces, especially at the conduit joints, which is more likely to occur, potentially leading to conduit breakage and affecting the normal operation of the pressure measurement. The rubber protective sleeves 6 can disperse external forces; when the conduit is bent or squeezed, the rubber protective sleeves 6 can... By using its own deformation to buffer external forces, the conduit avoids directly bearing excessive stress, thus effectively preventing kinking and breakage at the conduit connection, improving the stability of the conduit during use, and ensuring the smooth progress of pressure measurement. The lower part of the outer surface of the connecting screw 13 is threaded into the first threaded groove 12, thereby connecting the connecting screw 13 to the pipe body 11. Threaded connections are characterized by tightness and reliability. By rotating the connecting screw 13, the threads on its outer surface engage with the threads in the first threaded groove 12. As rotation continues, the connecting screw 13 gradually screws into the first threaded groove 12 until the two are tightly connected. This provides a foundation for subsequent connections to other components. The insertion tube 45 is inserted into the inner wall of the upper end of the connecting screw tube 13, initially connecting the airbag assembly 4 to the connecting screw tube 13. Simultaneously, the second screw groove 46 is threaded onto the outer surface of the connecting screw tube 13, further strengthening the connection. Furthermore, a limiting screw 44 passes through the sleeve 43 and contacts the connecting screw tube 13. Tightening the limiting screw 44 will firmly press against the connecting screw tube 13, thus securing the connection between the airbag assembly 4 and the connecting tube 1 (with the connecting screw tube 13 as part of the connecting tube 1). This multi-layered connection method ensures the robustness of the connection between the airbag assembly 4 and the connecting tube 1. The connection process mainly adopts a threaded connection method, which makes the connection between the airbag assembly 4 and the connecting tube 1 very convenient during installation and disassembly. During installation, the connection can be completed simply by rotating each component in the direction of the thread. When disassembly is required, the corresponding component can be easily separated by rotating it in the opposite direction. This improves the flexibility of the device during maintenance and component replacement, and facilitates practical use. In summary, this water-filled pressure measuring conduit, through effective protection of the conduit and a reasonable and easy-to-operate connection method between the components, improves the stability and maintenance flexibility of the pressure measuring conduit during use, and ensures the smooth progress of pressure measurement work.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
