カドランスデューサ。Figures 1 and 2 show how the urethral closure pressure is measured using a conventional urethral pressure detection device, and Figure 1 is a cross-sectional view showing the state where a catheter with one measurement hole is used. FIG. 2 is a sectional view showing a state in which a catheter with four measurement holes is used, taken on a plane perpendicular to the longitudinal direction of the catheter. Figures 3 to 10 show an embodiment of the present invention, with Figure 3 being a perspective view of the urethral pressure detection device, and Figure 4 being an enlarged sectional view showing the vicinity of the tip of the catheter in Figure 3. , Fig. 5 is a sectional view taken along the line ■-V in Fig. 4, Fig. 6 is a sectional view taken along the line VI-VI in Fig. 4, and Fig. 7 shows the measurement of the closing pressure of the urethra using the detection device shown in Fig. 4. Figure 8 is a block diagram showing an example of the closing pressure P□v P2 for each part of the inner wall of the urethra.
9 P3t p is an analog representation of P3t p over the entire length of the urethra, and Figure 9 shows the closing pressure P□?
P21 P3! It is a diagram showing P4 in polar coordinates for each pull-out distance. FIG. 10 is a diagram of polar coordinates drawn by subtracting the pressures P1 to P4 of each part from the maximum closing pressure. 10... Blind end catheter, 11... Measurement hole, 12.
