Is pivotally supported. Then, the waste tray 3 is located on the back surface of the holding sheet 2 and holds the horizontal state.

Next, the operation will be described based on the above-mentioned structure. In FIGS. 3 and 4, since the tilting cylinder 9 is contracted, the examination table 1 is in the upright state and the seat is driven. Since the working cylinder 11 is extended, the holding sheet 2 is located at the cut portion 1c of the seat portion 1a. In this state, the patient sits on the auxiliary seat 2 and puts the crotch on the crotch support 4. At this time, since the crotch support 4 is positioned in parallel with the extension line of the crotch rest portion 1d, the patient's crotch is not so expanded.

In this state, when the doctor examines or treats the patient, the examination table 1 is rotated so that the patient and the doctor face each other, and the lifting cylinder is placed so that the affected part is at the doctor's eye level. 6 is controlled to adjust the height.
Then, the tilting cylinder 9 is operated to lower the examination table 1 (FIGS. 5 and 6). In this state, the patient's buttocks are located at the boundary between the backrest 1b and the seat portion 1a, and the patient's weight is not applied to the auxiliary seat 2.

Further, the support cylinder 8 is supported by the tilting cylinder 9.
When the filth tray 3 is laid down, the filth tray 3 also tries to rotate along with the support base 8. However, since the lower portion of the filth tray 3 is pulled by the arm 16 having one end attached to the support bracket 7, the filth tray 3 is erected. It rotates with respect to the support base 8 with the upper part of 3a as a fulcrum, and is held in a horizontal state at the back surface position of the auxiliary sheet 2.

Next, the doctor uses the seat driving cylinder 11
When the cylinder is driven, the cylinder 11 contracts, so that the auxiliary seat 2 is guided by the guide pins 2a, 2b on the back side of the backrest 1b.
Slides by being guided by the guide holes 10a and 10b. At this time, since one end of the first link 12 is also pivotally supported by the guide pin 2a, the first link 12 also moves, but the second link 13 is guided by the guide hole 8b and moves in an arc. Since the second link 13 rotates with respect to the third link 14 via the connecting link 14a, the third link 14 is not affected at all (FIG. 7).

When the seat driving cylinder 11 is further contracted, the auxiliary seat 2 is further drawn toward the tip side (pillow side) of the backrest 1b, and the first link 12 is further moved. The second link 13 is guided and drawn into the straight portion of the guide hole 8b of the guide pin 12a.

Therefore, the third link 14 becomes the connecting link 14.
Although it is pulled by the movement of the second link 13 via a, the third link 14 is formed in a semi-circular shape and is guided by four guide rollers 15, so that the third link 14 has The opening / closing locus of the crotch support 4 attached to the distal end is rotated around a pseudo fulcrum centering on the ischial tuberosity of the patient, and the patient's legs are smoothly opened and closed (FIGS. 8 and 9).

The operation of the seat driving cylinder 11 is stopped at the position where the guide pins 2a, 2b are in contact with the ends of the guide holes 10a, 10b. In this state, the auxiliary sheet 2 is completely stored on the back surface of the backrest 1b, and the crotch support 4 is rotated so that the affected part of the patient can be seen well by the doctor. The operation from the state of the examination or treatment shown in FIGS. 8 and 9 to the standing state shown in FIGS. 3 and 4 is performed by the opposite operation to the above-mentioned operation.

[0031]

As described above, according to the present invention, the auxiliary seat is retracted by the initial drive of the seat drive cylinder, and the front surface of the affected area of the patient is opened to facilitate the medical examination and treatment by the doctor. The further movement of the cylinder rotates the crotch support to open the crotch of the patient, which makes it easier to perform examinations and treatments and keeps the crotch support closed during the waiting time. It can remove shame.

Further, since the rotation of the crotch support is performed by the guide of the semicircular arc-shaped link and the guide roller, the opening / closing locus of the crotch support serves as a pseudo fulcrum centering on the ischial tuberosity, and the movement of the crotch of the patient. Has an effect that it can be smoothly performed.
