[0002] In the medical field, the diagnosis and treatment of biliary tract diseases have always been the focus of clinical attention. Accurately obtaining the pressure information in the biliary tract is crucial for the diagnosis, treatment plan formulation, and prognosis evaluation of diseases such as gallstones, cholangitis, and biliary tract obstruction.

[0003] Currently, there are many drawbacks in the existing biliary tract pressure monitoring methods. Some traditional biliary tract pressure monitoring methods are invasive operations, which means that a greater degree of invasive operation on the patient is required during the monitoring process. This operation method not only brings great pain to the patient but also significantly increases the risk of patient infection. Once an infection occurs, a series of serious complications may be triggered, further aggravating the patient's condition and prolonging the patient's recovery time. Moreover, most existing methods can only perform intermittent pressure measurements and cannot achieve real-time and continuous monitoring of biliary tract pressure, which may lead to the omission of some important pressure change information, thus affecting the doctor's accurate judgment of the condition and treatment decision-making. In addition, the existing monitoring devices also have deficiencies in measurement accuracy, stability, and data processing and analysis capabilities, and are difficult to meet the increasingly high clinical requirements. The existing monitoring devices have obvious limitations in data processing and analysis capabilities.
