A pair of leg rests is provided at the lower end of the bed. The patient stands on the couch with the legs in an open position, and the thighs are fixed to the bed. The consultation room is divided into a patient space and a consultation space by a curtain that is lowered to the patient's abdomen.The examination table is installed directly under the curtain, and when the patient gets on and off the examination table, the examination room She may be exposed to the gaze, and in some cases may be kept waiting in a consultation posture, and suffers from shame and anxiety. Furthermore, it is burdensome for the expectant mothers if the patient takes a supine position on the bed.

Further, as shown in FIG. 11, since the leg rests (4) and (4) are rotatably supported by pivots (43) and (43) projecting from the lower end surface of the back plate (31), both leg rests are placed. The table is rotatable sideways with respect to the back plate (31). Since the buttocks (92) of the patient (9) ride on the base end side of the both-leg rests (4) and (4), when the two-leg rests are opened and closed in the same plane as described above, Place (4)
When (4) is opened, a part of the buttocks (92) sinks between the leg rests (4) and (4), and the leg rests (4) and (4) are closed as indicated by the arrow A. There was a concern that the meat of the buttocks was pinched. Therefore, as shown in FIG. 12, the applicant has previously proposed a screening table in which a seat (3) is provided on a base (1) so as to be able to move back and forth, ascend and descend, and tilt backward (Japanese Patent Publication No. Hei 4-176662). . The seat (3) is composed of a back plate (31) and a pair of leg rests (4) and (4) pivotally supported by a lower end of the back plate so as to be able to approach and separate from each other, and rise while moving forward. I do. The examination table above is the patient side space of the examination room

The lower ends of both mounting plates (49) (49) are connected by a connecting bar (40). A pair of arms (2) (2) supporting the seat (3)
Are formed by parallel links (21) and (21), the lower end of the link (21) is pivotally supported by the base (1), and the upper end of the link (21) is a connecting plate.
It is pivotally connected at (22). The central portions of the links (21) and (21) are connected by a connecting plate (23). One end of the connecting plate (23) is pivotally supported on one link (21) by a shaft (23a), and the other end is long. A shaft (23c) having a hole (23b) opened and protruding from the other link (21) in the slot.
Is slidably fitted.

The central portions of the connecting plates (23) of both arms (2) are connected by connecting rods (24), and the connecting rods are used to drive the rotation of the arms.
Connect (5). The driving device (5) of the embodiment is a hydraulic cylinder device, which pivotally supports a base end of a cylinder (51) to a rear end of a base (1) and pivots a piston rod (52) to a connecting rod (24). It is connected. When the piston rod (52) is protruded, both arms (2) and (2) simultaneously rotate forward. Both arms (2) (2)
The connecting plates (22) and (22) at the upper end of the front are extended forward, and the extended ends are attached to the upper ends of the mounting plates (49) and (49) projecting from the seat (3).
Connect pivotally at 7). A base plate (25) is fixed across the leading ends of the connecting plates (22) and (22), and a central portion of the base plate is brought into contact with a connecting rod (46) of the opening / closing device (7) for the leg rest. Contactable contact member (46a)
Is fixedly deployed. The rotary drive (6) is connected to the seat (3). The rotation drive device (6) is a hydraulic cylinder device (61), which enables the hydraulic cylinder device (6) to rotate in a vertical plane on both connecting plates (22) (22) of the arm (2). In support, the piston rod (62) is pivotally connected to the connecting bar (40) on the seat (3). When the piston rod (62) of the cylinder device (61) is protruded, the seat (3) falls backward about the pivot (27). A bellows-type cover (11) is mounted between the back plate (31) of the seat (3) and the base (1).

[0013] However, the state where the arm (2) is tilted backward,
That is, at the position where the seat (3) is lowered, the leg rest (4)
The patient (9) is seated on the thighs (91) and (91) on (4). The driving device (5) for the arm (2) and the driving device (6) for the seat (3) are simultaneously operated. The arm (2) rotates forward, and the seat (3) moves forward while rising. When the arm (2) is in the vertical position, the height of the seat (3) reaches the highest position, and then it moves forward while descending and moves under the curtain (8) to the consultation space. When the height of the seat 3 reaches the consultation position, the advance of the seat is stopped and the seat 6 is tilted backward by the driving device 6. When the seat (3) falls backwards, the footrest (4)
The connecting rod (46) of the opening / closing device (7) of (4) hits the contact member (46a), and the operating rods (44) and (45) protrude forward against the spring (48), and the arm rod (44) is moved. Rotate to open between the leg rests (4) (4). That is, the leg rests (4) and (4) rotate so that their tips approach the upper end of the back plate (31). The weight of the patient acts on the platform (4) downward, and the platforms (4) and (4) are pushed inward by the force of the patient's legs closing.
For this reason, the mounting base (41) has a long hole with respect to the connecting shaft (405).
It rotates in the direction in which the inner edge (4a) goes down in the range of (403a). A part of the buttocks (92) of the patient (9) sinks between the base ends of the mounting tables (4) and (4). As described above, since the inner edge (4a) of the mounting table main body (41) is lowered, it does not interfere with the examination.

After the consultation, when each of the driving devices is operated in the opposite direction to the above, the foot rests (4) and (4) are closed, the examination stand returns to its original position, and the patient moves to the seat (3). ) You can get off. When the leg rests (4) and (4) are closed, the leg rests (4) and (4) are, as shown by arrows B in FIGS. Descends while drawing an arc inward. That is, the free ends of the mounting tables (4) and (4) are
Close while displacing away from the top edge of the. 4 of FIG.
When the footrests (4) and (4) are closed, the opposing inner edges (4a) and (4a) of the footrests (4) and (4) are pivoted to the pivots (4) as indicated by the chain lines.
3) Since it protrudes inward from the vertical plane F including the axis of (43), immediately before closing, the inside of the base end side of the two foot rests (4) and (4) is located on the buttocks (92) of the patient. It wraps down from the side and approaches so as to wrap around the buttocks (92). Immediately before the closing of the leg rests (4) and (4), the protruding piece (406) of the connecting shaft (405) comes into contact with the stopper (407).
In the meantime, the leg rest body (41) has its inner edge connected to the connecting shaft (405).
Turn a little in the direction of high lifting around. This more effectively prevents the patient's buttocks (92) from being pinched between the leg rests (4). In the embodiment, as shown in FIG. 8, the projecting piece (406) hits the stopper (407) 5 ° before the end of the closing of the leg rest (4), and at the end of the closing, the stand main body (41) connects the connecting shaft. (405), the mounting base body (41) rotated by 15 °
Are configured to be substantially horizontal.

In order to pivot the leg rest (4) to the back plate (31), a pivot (43) is protruded from the back plate (31), and the leg rest (4) is supported by the pivot (43). Of course, (4) can be rotatably supported. Further, as described above, the present invention is not limited to the case where the seat (3) moves back and forth and moves up and down, but can be implemented as long as the seat is tilted backward. Various modifications are possible.
