Next, when the patient is placed in a supine position by tilting the backrest down, the seat is retracted from below the buttocks by the displacement means, eliminating the need for the patient to move forward and making the examination easier. .

〔Example〕

Next, an example of implementation of the present invention will be described below with reference to FIGS. 1 to 5.

Reference numeral 1 denotes an installation stand installed on the floor, and on its lower surface are provided at several locations an adjuster 2 that moves up and down by rotation, and casters 3 for movement.

When this adjuster 2 is raised, caster 3
is in contact with the floor, and the installation base 1 can move on the floor due to its rolling. However, when the adjuster 2 is lowered, the caster 3 leaves the floor, the installation base 1 is installed at that location, and each adjuster 2 By adjusting the height, the installation stand 1 is prevented from wobbling and kept level.

A movable base 5 is attached to the installation base 1 so as to be movable in the front-rear direction using a slide bearing 4, and a cylinder 6 is mounted between the support piece 5a of the movable base 5 and the installation base 1. ing.

A lifting cylinder 11 and a cover 8 are attached to the moving table 5 via a mounting base 7, and the ram of the lifting cylinder 11 has a roller that rolls along the lifting cylinder 11 and guides the lifting. An elevating outer cylinder 9 having a diameter of 10 is attached.

Therefore, when the lifting cylinder 11 operates, the roller 10 rolls on its outer peripheral surface, and the lifting outer cylinder 9 moves up and down.

The upper surface of the elevating outer cylinder 9 has a backrest 15 as a fulcrum C.
A tilting cylinder 13 is mounted between a fulcrum B of the backrest portion 15 and a fulcrum A of the elevating outer cylinder 9. Note that the portion from the movable table 5 to the bracket 12 may be integrated into a support table that can be moved relative to the installation table 1.

Now, when the tilting cylinder 13 is in the extended state, the backrest portion 15 is in the upright state due to the fulcrum B, but when the tilting cylinder 13 is in the contracted state, the fulcrum B is
B', and the backrest 15 falls backward as shown by the dashed line in FIG.

An auxiliary seat 16 is fixed to the lower end of the backrest portion 15.

In addition, four guide rollers 21 are provided on the backrest portion 15.
is rotatably attached, and an arc-shaped slide bar L, which pivots the seat 17 at a fulcrum I, is supported by the guide roller 21 so as to be movable back and forth.

An extrusion cylinder 14 is mounted between the fulcrum E of the slide bar L and the fulcrum D of the backrest portion 15,
When the extrusion cylinder 14 is in the extended state,
Since the slide bar L is moved forward, the seat 1, which is pivoted to the slide bar L at a fulcrum I,
7 moves forward and downward of the backrest portion 15.

A protrusion 17b with one side as a hypotenuse 17a is protruded from the lower surface of the seat 17, and a protrusion 15a is protruded from the backrest 15, so that the seat 17 can be positioned in front of the backrest 15 as described above. When in the lower position, the protruding portion 17b rides on the protruding rod 15a, and the backrest portion 15
It is close to the lower front of the.

When the extrusion cylinder 14 is in a contracted state, the fulcrum E is pulled and the slide bar L tries to move rearward while being guided by the guide roller 21.

Then, since the seat 17 also tries to move rearward, the protruding part 17b tends to shift backward from the position of the protruding rod 15a, so that the oblique side 17 of the protruding part 17b
a slides down the protrusion 15a as shown by the two-dot chain line in FIG. 1, and the seat 17 separates downward from the backrest 15.

Further, the rearward movement of the slide bar L continues, and the seat 17 is pulled below the auxiliary seat 16 as shown by the dashed line in the figure.

On the other hand, when the extrusion cylinder 14 extends, the oblique side 17a is guided by the protrusion 15a, and the sheet 1
When seat 7 is in the most advanced position, seat 17
is raised, and the seat 17 approaches the lower front of the backrest 15. As described above, the displacement means for moving the sheet 17 includes at least the extrusion cylinder 14, the slide bar L, and the guide roller 2.
Consists of 1.

A cover 23, which is biased by a spring 22, is pivotally attached to the backrest portion 15 at a fulcrum P, and when the slide bar L is moving forward as described above, the cover 23 is attached to the seat. 17. It is tilted forward by the pressure of the slide bar L against the bias of the spring 22.

However, when the slide bar L retreats, the pressure on the cover 23 is removed, and the spring 22 biases the slide bar L into an upright state as shown by the dashed line in FIG. 1, covering the front surface of the seat 17 that has retreated.

Furthermore, a fixed base 24 for attaching a sewage tray 27 is pivotally attached to the backrest portion 15 at a fulcrum H, and a link 25 is mounted between the fulcrum G of the arm 24a and the fulcrum F of the bracket 12. ing.

Therefore, even if the backrest portion 15 is raised and lowered as described above, the fixed base 24 is always kept horizontal due to the relationship between the fulcrums G and F.

Since this examination table has the above-described configuration, the tilting cylinder 13 is in the extended state and the backrest portion 15 is
is placed in an upright position, the extrusion cylinder 14 is extended, and the seat 17 is brought close to the lower front of the backrest 15, so that the patient can sit on the seat 17.

At this time, the cover 23 is tilted forward and the fixing base 24
is below the auxiliary sheet 16 while maintaining its horizontal position.

After the patient is seated on the seat 17 in this state, when the cylinder 6 is operated to contract it, the movable table 5 moves forward on the slide bearing 4 because the support piece 5a is pulled.

Next, the tilting cylinder 13 is operated to tilt the backrest 15 backward, but at this time, the patient's lower limbs are placed on the crotch support 26 attached to the backrest 15 as shown in FIG. I'll keep it.

By tilting the backrest 15 backward, the patient assumes a supine posture, and then the push-out cylinder 14 is operated to pull the slide bar L backward.

Then, the sheet 17 has the protruding portion 17b aligned with the protruding rod 15.
By coming off from a, the patient's buttocks in the supine position are in a floating state because the patient's buttocks in the supine position are in a floating state because the patient's buttocks in the supine position are suspended, as the patient's buttocks in the supine position are lifted up because the patient's buttocks in the supine position are suspended.
This is the posture for receiving a checkup or medical treatment.

At this time, the fixed table 24 is located below the front of the auxiliary seat 16 and maintains a horizontal state, so if the waste water tray 27 is attached to this table, the waste water used in medical treatment etc. can be received there.

Further, since the cover 23 stands up on the front surface of the seat 17, it is possible to prevent splashes from the sewage tray 27 from splashing onto the seat 17.

The patient's height is adjusted by raising and lowering the elevating outer cylinder 9, and examinations and medical treatment are performed.

In this way, after the patient's examination or medical treatment is completed, the push-out cylinder 14 moves in the opposite direction to support the patient's buttocks with the seat 17, and then the tilting cylinder 13 moves in the opposite direction to support the patient's buttocks. Raise the patient and return the patient to a sitting position.

At this time, even if the sewage tray 27 is not removed from the fixed table 24, the fixed table 24 always remains horizontal, so sewage will not spill from the sewage tray 27, and the patient will be able to move forward as the seat 17 moves forward. The sewage tray 27 does not interfere with getting off or getting on the seat 17.
