Meanwhile, a millisecond active pressure relief is triggered by a system host when pathological spasm is monitored, and a pressure-time integral (PTI) is calculated in real time to quantify a liquid absorption risk.

The present invention relates to a medical instrument, which is an examination instrument for measuring pressure within a bladder. The technical problem to be solved by the present invention is that existing traditional urodynamic devices have the issue of requiring external connecting tubes, existing wireless bladder pressure measuring devices have the issue of their own weight compressing the bladder wall, and existing wireless bladder pressure measuring devices in a curled form require straightening the curled shape during placement and removal, which may cause pain. The present invention proposes a wireless, implantable examination instrument for measuring pressure within a bladder, which requires no external catheters or external wires and can be suspended within the bladder. According to the present invention, the instrument is in a multi-segment tubular form, comprising buoyancy tube segments located at both ends and a device tube segment located in the middle, with elastic connection segments between the buoyancy tube segments and the device tube segment. The diameters of the buoyancy tube segments, the elastic connection segments, and the device tube segment are all smaller than the diameter of the urethra, allowing the bladder pressure measuring instrument to be entirely placed into the bladder through the urethra. The interior of the device tube segment can accommodate components such as a power supply, a circuit board, a pressure sensor, and a wireless communication module. The buoyancy tube segments are internally filled with gas or a low-density lightweight material. According to the present invention, the bladder pressure measuring instrument can interconnect wirelessly with other devices, such that the operation and data transmission of the bladder pressure measuring instrument can be regulated and controlled in a wireless mode.
