Description

Technical Field

[0001] The utility model relates to the technical field of urodynamic air-conducted pressure sensors, in particular to a urodynamic air-conducted pressure sensor with an auxiliary pressurizing device. Background Technique

[0002] Urodynamic pressure sensors, as an important tool in modern medical technology, when used in combination with urodynamic analyzers, provide doctors with key data for accurately diagnosing a patient's bladder pressure, urethral pressure, and abdominal pressure. The accuracy of this data is directly related to doctors' judgment of the patient's condition and the formulation of subsequent treatment plans.

[0003] In actual operation, the working principle of the urodynamic pressure sensor is to capture and convert pressure signals through its special structure. One end of the pressure measuring catheter is equipped with a balloon, which can sense the pressure changes from the patient's body. When the balloon is subjected to pressure, its volume will change accordingly, and this change is transmitted to the sensing diaphragm of the sensor chip through the pressure transfer tube. The sensing diaphragm will deform under the action of pressure, and this deformation is captured by the internal circuit system of the sensor and converted into an electrical signal. These electrical signals are then transmitted to the urodynamic analyzer, and after processing, the pressure data inside the patient's body can be obtained.

[0004] However, before pressure detection, a crucial step is to pre-pressurize the balloon of the pressure measuring catheter. Currently, the commonly used pre-pressurization method is to manually pressurize the balloon with a syringe or other pressurizing tools. This process requires careful operation by doctors or nurses to ensure that the pressure inside the balloon reaches the preset value. After pressurization, a on-off valve (two-way valve) needs to be connected at the catheter joint to close the cavity where the catheter balloon is located and maintain the inflated state of the balloon. Then, the pre-pressurized pressure measuring catheter is connected to the pressure sensor for pressure measurement.

[0005] This pressurization and depressurization method has some problems in actual operation. First, doctors or nurses need to repeatedly operate the syringe and the on-off valve, which increases the complexity of the operation and the diagnosis time. Second, during the pressure measurement process, the balloon needs to be inserted into the patient's body, and this invasive operation will cause certain discomfort to the patient. Especially during the pressurization and depressurization processes, due to the need to frequently operate the syringe and the on-off valve, the patient's discomfort will be further enhanced.
