[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 The present invention provides an embodiment of an esophageal pressure measuring catheter with an improved structure, comprising a hose 1. The hose 1 serves as the main structure of the esophageal pressure measuring catheter, carries other components, and provides an installation base for a pressure sensor 2 and the like. The hose 1 is also the main component for inserting the catheter into the esophagus, facilitating placement in the esophagus and pressure measurement. The hose 1 is fixedly connected to the outside of the catheter. The pressure sensor 2 can sense pressure changes in the esophagus in real time and convert the pressure signal into an electrical signal or other identifiable signal, providing key data for esophageal pressure measurement.

[0032] Reference Figures 2 to 4A groove 3 is provided inside one end of the hose 1. The groove 3 is used to achieve a detachable connection with the ring plate 4, which is convenient for installing, disassembling, maintaining or replacing the ring plate 4 and connected components when needed. The inner wall of the groove 3 is detachably connected to the ring plate 4. The ring plate 4 plays the role of connecting transition, providing a basis for fixed installation of the connecting column 5, ensuring the stable setting of the connecting column 5 and subsequent components on the hose 1. The inside of the ring plate 4 is fixedly connected to the connecting column 5. The connecting column 5 is the core connecting structure for the installation of multiple components. It is fixedly connected to the ring plate 4 internally and fixedly connected to the telescopic support frame 6, the fixing frame 8 and other components on the outside to ensure the stable positional relationship between the components.

[0033] The outside of the connecting column 5 is fixedly connected to a telescopic support frame 16. During the process of inserting the catheter into the esophagus, the telescopic support frame 16 can be deformed and expanded to a certain extent according to the internal space and shape of the esophagus, playing a supporting role, ensuring that the hose 1 maintains a suitable shape and position in the esophagus, facilitating accurate pressure measurement. The inside of the hose 1 is fixedly connected to a telescopic support frame 27. The telescopic support frame 27 cooperates with the telescopic support frame 16 to further enhance the supporting effect of the hose 1, making the hose 1 not easily deformed or bent in the esophagus, thereby ensuring the accuracy and stability of pressure measurement.

[0034] The outside of the connecting column 5 is fixedly connected to a fixing frame 8, which is used to install components such as the connecting frame 9 and the reset assembly, providing a mounting carrier for these components so that they have a stable mounting position on the catheter to ensure the integrity of the entire device structure. The inside of the fixing frame 8 is fixedly connected to multiple connecting frames 9, which provide a structural basis for the rotational connection of the card plate 10, so that the card plate 10 can rotate flexibly in the connecting frame 9 to achieve engagement and separation with the card slot 20 on the connecting column 5.

[0035] The interior of the connecting frame 9 is rotatably connected to a card plate 10, which serves to fix the connecting column 5 and the fixing frame 8. The exterior of the card plate 10 engages with the inner wall of the card slot 20 on the connecting column 5 to ensure a firm connection between the two. At the same time, it can rotate when subjected to external force to achieve operations such as separation from the card slot 20. A reset assembly is provided inside the fixing frame 8. The reset assembly includes a plurality of connecting columns 11, which are fixedly connected to the interior of the fixing frame 8 to provide an installation support structure for the spring 12 and the rubber plate 13, determine the position of the spring 12 and the rubber plate 13 in the fixing frame 8, and ensure the normal operation of the reset assembly.

[0036] The outside of the connecting column 11 is fixedly connected to the inside of the fixing frame 8. Two springs 12 are sleeved on the outside of the connecting column 11. The springs 12 use their own elasticity to apply elastic force to the rubber plate 13 when the card plate 10 is moved by external force, thereby realizing the reset function of the card plate 10 and related components and maintaining the stability of the device structure. The outside of the connecting column 11 is slidably connected to the rubber plate 13. When the card plate 10 moves, the rubber plate 13 is displaced by the elastic force of the spring 12, assisting the card plate 10 to reset, and at the same time, it contacts the connecting column 5 during the movement, which can play a certain buffering and limiting role.

[0037] One end of the spring 12 is fixedly connected to the outside of the fixing frame 8, and the other end of the spring 12 is fixedly connected to the outside of the rubber plate 13. The outside of the connecting column 5 is in contact with the outside of the rubber plate 13. A plurality of slots 20 are provided on the outside of the connecting column 5. The slots 20 are used to limit the position of the card plate 10, ensure the stability of the connection between the connecting column 5 and the fixing frame 8, and also provide a positioning reference for the rotation and reset of the card plate 10. The outside of the card plate 10 is engaged with the inner wall of the slot 20.

[0038] Reference Figures 5 and 6 A fixing assembly is provided on the outside of the fixing frame 8, and the fixing assembly includes a fixing block 14. The fixing block 14 is the basic connecting component of the fixing assembly and is fixedly connected to the outside of the fixing frame 8 to provide an installation position for the strap 15, the strap 2 17 and the ring piece 19, so that the fixing assembly can be stably set on the outside of the fixing frame 8. The outside of the fixing block 14 is fixedly connected to the outside of the fixing frame 8. The outside of the fixing block 14 is fixedly connected to the outside of the fixing frame 8. The strap 15 is fixedly connected to the outside of the fixing block 14. The strap 15 cooperates with the hook surface 18 on the outside of the strap 2 17 through its outer furry surface 16 to fix the esophageal manometry catheter in a specific position.

[0039] By adjusting the length and position of the first strap 15, the catheter can be firmly fixed during use. The outside of the first strap 15 is fixedly connected with the furry surface 16, and the furry surface 16 and the hook surface 18 on the outside of the second strap 17 are adhered to each other, which plays the role of fixing the first strap 15 and the second strap 17, thereby fixing the esophageal pressure measuring catheter. The pasting position and tightness can be adjusted according to actual needs. The outside of the fixing block 14 is fixedly connected with the second strap 17, and the second strap 17 cooperates with the first strap 15, and the hook surface 18 on its outside is adhered to the furry surface 16 to achieve the fixing operation of the esophageal pressure measuring catheter.

[0040] Together with the strap 15, the fixed position and stability of the catheter are determined. The outside of the strap 2 17 is fixedly connected with a hook surface 18, and the hook surface 18 and the hairy surface 16 are pasted to each other, which are used to connect the strap 15 and the strap 2 17 together, thereby achieving the fixation of the esophageal pressure measuring catheter, and conveniently and quickly adjusting and fixing the position of the catheter. The outside of the hairy surface 16 is in contact with the outside of the hook surface 18. The side of the fixing block 14 away from the fixing frame 8 is movably connected with a ring piece 19. The ring piece 19 may be used to assist the fixing operation. For example, in some cases, the ring piece 19 can be used to thread a wire or cooperate with other components to further enhance the fixing effect of the catheter, or play an auxiliary role in the process of catheter storage.

[0041] Working principle: First, fix the pressure sensor 2 on the outside of the hose 1 to sense pressure changes. To ensure its normal function, install the ring plate 4 to the inner wall of the groove 3. The inside of the ring plate 4 is fixedly connected to the connecting column 5. The connecting column 5 is fixed with a telescopic support frame 6 and a fixing frame 8. During assembly, the card plate 10 must be accurately inserted into the card slot 20 to stably connect the connecting column 5 with the fixing frame 8 and other components. When not in use, the spring 12 is in a normal state, preparing for possible subsequent reset operations. When the card plate 10 moves under some operations, the rubber plate 13 may be squeezed, and the spring 12 will be compressed or stretched accordingly. When the external force disappears, the spring 12 can rely on its own elasticity to drive the rubber plate 13 and related components to reset, ensuring that the card plate 10 can return to the appropriate position and maintain the stability of the device structure.

[0042] If the esophageal pressure measuring catheter needs to be fixed in a specific position, the first and second bandages 15 and 17 can be used. Bandages 15 and 17 are placed around the desired location, and then the fleece surface 16 and hook surface 18 are brought into contact and adhered. The tightness of the bandages is adjusted to secure the catheter. Once all components are in place, the esophageal pressure measuring catheter is inserted into the esophagus. During insertion, the telescopic support frame 1 and the second telescopic support frame 7 fixed inside the hose 1 provide support, ensuring that the hose 1 maintains the proper shape and position within the esophagus for accurate measurement. Pressure sensor 2 senses the pressure conditions at different locations within the esophagus in real time and converts the pressure signals into electrical signals or other recognizable signals. These signals can then be collected and analyzed by relevant equipment, providing data for medical diagnosis.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
