The present invention relates to a medical instrument that is an examination instrument for measuring the
internal pressure of the bladder that requires no externally connected
catheter or externally connected cable. The technical problems addressed by the present invention are that existing conventional urodynamic
bladder pressure measuring devices require externally connected catheters and cables, the non-closed-loop structures of existing
wireless bladder pressure measuring devices involve the risk of the end heads entering the
urethra and becoming dislodged, and the tubular structures uniform in
diameter in existing
wireless bladder pressure measuring devices fail to balance good flexibility and a
large capacity. The present invention provides an annular
wireless bladder pressure
measuring instrument for measuring the
internal pressure of the bladder that requires no externally connected
catheter or externally connected cable, can be placed in the bladder, and features good flexibility and a
large capacity. The present invention is of an annular structure and is made of an elastic material, so that the present invention can be flattened and elongated under
external pressure and automatically springs back into an annular shape when no
external pressure is applied. The annular structure comprises a folding section and a loading section; the folding section is relatively thin and can be bent and straightened easily, and the loading section is relatively thick and has a large internal space that can accommodate elements such as a power supply, a circuit board, and a
pressure sensor. The bladder pressure
measuring instrument can be wirelessly interconnected to other devices. Data from the
pressure sensor can be wirelessly transmitted. The operation of the bladder pressure
measuring instrument can be regulated wirelessly.
