[0002] In the modern medical field, accurate assessment and monitoring of patient conditions are of great importance. Among them, the measurement of bladder pressure is an operation with important clinical significance. As an important part of the human urinary system, the pressure change of the bladder can reflect a variety of physiological and pathological conditions. Accurate measurement of bladder pressure plays a key guiding role in the diagnosis and treatment of many diseases, such as urinary obstruction, neurogenic bladder dysfunction, and abdominal pressure-related diseases.

[0003] For example, in the intensive care unit (ICU), patients often have elevated intra-abdominal pressure due to various reasons, and bladder pressure is closely related to intra-abdominal pressure. By measuring bladder pressure, intra-abdominal pressure can be indirectly assessed, and abdominal hypertension can be detected in a timely manner to prevent the occurrence of serious complications such as multiple organ dysfunction syndrome. In addition, measuring bladder pressure before and after urological surgery helps to understand the functional status of the bladder, assess the effectiveness of surgery, and guide the development of subsequent treatment plans.

[0004] The existing measurement method is to use a catheter and an infusion device. The principle is as follows: after inserting the catheter into the bladder, connect the infusion device, inject a certain amount of normal saline into the bladder, and then use the pressure of the liquid in the infusion device to indirectly reflect the bladder pressure.
