A cylindrical upright pole 13 is integrally formed on the upper side of the first fixing plate; an external thread is formed on the upper part of the upright pole 13; a tube body 13a is installed on the upper part of the upright pole 13; an internal thread is formed on the inner periphery of the upper part of the tube body 13a, and there is no thread on the inner periphery of the lower part of the tube body 13a. The tube body 13a is combined with the external thread on the upper part of the upright pole 13 through its internal thread.
[0023] The arm pressing unit 20 includes a cross arm 21, on which a slider 24 is mounted. A collar 21b is formed on the first end of the cross arm 21, on which a second screw hole is formed, in which a second bolt 21c is mounted, and the collar 21b is slidably mounted on the vertical rod 13, located at the lower side of the tube body 13a.
[0024] The second bolt 21 c fixes the collar 21 b on the upright pole 13 .
[0025] A first through hole 24a in the up and down directions is formed in the middle of the slider 24; a pressing rod 22 can be slidably installed in the first through hole 24a; the upper end of the pressing rod 22 passes through the first through hole 24a and is located above the slider 24; the lower end of the pressing rod 22 extends to the bottom of the slider 24; the pressing rod 22 is equipped with a pressing head 23 made of silicone at the lower end; a stopper 22a is formed at the lower part of the pressing rod 22; a solenoid spring 22b is arranged around the upper part of the pressing rod 22; the upper end of the solenoid spring 22b is supported on the lower side surface of the slider 24, and the lower end of the solenoid spring 22b is supported on the upper side surface of the stopper 22a.

[0031] When in use, first fix the base unit to the bed with the first bolt; then let the patient lie on the hip support board; rotate the cross arm with the vertical pole as the axis, and then slide the slider so that the pressing head of the pressing rod is pressed just above the femoral artery puncture point, and the solenoid spring does not deform at this time. Fix the position of the slider with the third bolt; then rotate the tube body so that the cross bar moves downward with the slider, thereby compressing the solenoid spring through the slider; at this time, the upper part of the pressing rod extends further upward from the first through hole of the slider; the pressure indicator scale on the pressing rod can be used to know the degree of pressure on the puncture point at this time. After the pressure value is adjusted to the appropriate value, stop rotating the tube body; in order to prevent the cross bar from rotating around the vertical pole, tighten the second bolt to fix the collar.
