It is known from the publication No. 63-286155.

This conventional examination table allows the patient to take a vertical sitting position on the seat board and then adjust the patient's body position to a horizontal position by tilting the back board backwards. The sewage receptacle, which is linked to the back plate via a link mechanism, is configured to be automatically pulled out from the storage position to the draw-out position below the patient's examination as the back plate tilts backward. Note that the wastewater receiver pulled out to the drawn-out position receives the wastewater used to wash the patient's examination area.

D Problems to be Solved by the Invention This conventional examination table has a structure in which the sewage receiver is mechanically fully interlocked with the back plate by a link mechanism and is pulled out from the storage position to the drawn-out position. It is completely impossible to push the drawn-out sewage receptacle back freely by hand. Furthermore, the drawer position of the wastewater receptacle is always constant.

However, during a patient's examination, the doctor may or may not wash the patient's examination area, and if the doctor does not clean the area, the dirty water receptacle pulled out to the drawer position may become an obstacle for the examination or other purposes. There was a problem with putting it away.

Also, if the drawer position of the wastewater receptacle is always the same,
There was also the problem that the sewage basin could become a hindrance to medical examinations and other tasks due to differences in the height of the doctors.

G Example Hereinafter, an example in which the present invention is applied to an examination table for obstetrics and gynecology will be described with reference to the drawings.

_G1 First, the entire examination table will be explained with reference to FIGS. 1A and 1B.

This examination table has a seat plate 2 constituting a patient placement part 1, a back plate 3 and 4 divided into upper and lower parts, a pair of left and right crotch supports 5, an arm rest 6 that also serves as an upper limb support, etc. . These placing parts 1 are supported on a base 7 so as to be movable up and down by a lifting device which will be described later. The back plates 3 and 4 are supported by an angle changing mechanism and a back and forth moving mechanism, which will be described later, so that the angle can be changed and the back plates 4 can be moved in the front and rear directions relative to the seat plate 2. Further, a sewage receiver 8, a sewage scattering prevention plate 9, etc., which can be taken in and out, are provided at the lower part of the seat plate 2.

According to this examination table, first, as shown in FIG. 1A, a patient is placed on the platform 1 with the platform 1 being lowered to the lowered position. At that time, the patient places his buttocks on the seat plate 2, leans his lower back and back on the back plates 3 and 4, and places his legs on the thigh support 5 with both legs spread apart. Take a vertical position.

Next, the placing unit 1 is raised obliquely forward in the direction of arrow a from the lowered position shown in FIG. 1A to the upper front elevation position shown in FIG. 1B. Crotch support 5 and elbow support 6

The back plate 3 on the tip side is moved to a position above the seat plate 2 by moving it forward.

Then, by tilting the back plates 3 and 4 backward, the patient's waist and back come to rest almost horizontally on the back plates 3 and 4, and the patient's center of gravity moves from above the seat plate 2 to above the back plates 3 and 4. At the same time, the patient's body position is adjusted to a horizontal position with legs tilted backwards.
Then, the patient is moved forward while remaining in the horizontal position by moving the placing section 1 obliquely forward in the direction of arrow a and moving the back plates 3 and 4 forward in the direction of arrow c. , the patient's seat (examination area) is brought closer to the doctor through the curtain.

At this time, by moving the back plate 3 to a position above the seat plate 2 in the direction of arrow c, as a result,
The seat plate 2 is stored under the back plate 3 in a direction opposite to the direction of arrow c. In addition, as the back plate 3 moves in the direction of arrow c, the sewage receiver 8 and the sewage scattering prevention plate 9
is automatically pulled out from the storage position at the bottom of the seat plate 2 to the pull-out position in front of the seat plate 2.

This examination table has all controls such as raising and lowering the platform 1, changing the angle of the back surfaces 3 and 4 with respect to the seat plate 2, moving them back and forth, and putting in and taking out the sewage receiver 8 and the sewage scattering prevention plate 9. This is done by a foot switch (not shown).

G ₂ Next, the elevating device 11 of the placing section 1 will be explained with reference to FIGS. 2A to 2C.

This elevating device 11 has parallel links 14 of equal length constituting a first parallel link mechanism 13 attached to a lower bracket 12 fixed to a base 7.
The front end side of the arrow a,
It is mounted so that it can rotate freely in the a′ direction. and,
The rear end side of the parallel link 14 is rotatably attached to the intermediate bracket 15 by a rotation fulcrum 14b, and the rear end side of the parallel link 17 of equal length constituting the second parallel link mechanism 16 is attached to the rotation fulcrum 17a. Therefore, it is mounted rotatably in the directions of arrows d and d'. And parallel link 17
The mounting portion 1 is attached to an upper bracket 18, the front end of which is rotatably attached via a rotation fulcrum 17b. Note that the first parallel link mechanism 13 is long and the second parallel link mechanism 16 is long.
is short and structured. A first drive means 19 swings the first parallel link mechanism 13 relative to the lower bracket 12 in the directions of arrows a and a' about the rotation fulcrum 14a, and a second parallel link mechanism relative to the intermediate bracket 15. A second drive means 20 is separately provided for swinging the mechanism 16 in the directions of arrows d and d' about the pivot point 17a. Incidentally, these first and second driving means are constituted by hydraulic cylinders.

According to this elevating device 11, the first parallel link mechanism 13 is swing-driven with respect to the lower bracket 12 in the directions of arrows a and a' about the pivot point 14a by the first driving means 19. Then, this first parallel link mechanism 13 is connected to the second parallel link mechanism 13.
As shown in Figure A, the lower bracket 12 is laid down almost horizontally on the rear side, and the second B
As shown in the figure, it can be driven to swing between the folded position and the upright position, which is raised forward and upward to a predetermined angle. At this time, since the first parallel link mechanism 13 performs a parallel movement, the placing portion 1 is moved between the lowered position shown in FIG. 2A and the raised position shown in FIG. It can be raised and lowered by parallel movement in the direction. Therefore, the seat plate 2 is raised and lowered while always maintaining a substantially horizontal state. and,
By raising the receiver 1 diagonally forward in the direction of arrow a from the lowered position to the upper position, the patient's seat (examination section) on the receiver 1 can be brought closer to the doctor through the curtain. .

Next, when it is necessary to adjust the height of the platform 1 that has been raised to the raised position, the second parallel link mechanism 16 is moved to the intermediate bracket 15 by the second driving means 19, as shown in FIG. 2C. On the other hand, the height of the mounting portion 1 can be freely adjusted by swinging in the vertical direction, that is, the directions of arrows d and d' about the pivot point 17a. At this time, since the second parallel link mechanism 16 performs a parallel movement, the patient's seat on the mounting section 1 (examination section)
The height can be adjusted with almost no change in the position in the front-rear direction, ie, the direction of arrow e.

_G3 Next, the angle changing mechanism 22 of the back plates 3 and 4 will be explained with reference to FIGS. 3A to 3D.

A pair of left and right guide rollers 35 are attached to the lower end of the roller 6. A seat plate base 36 of the seat plate 2 is commonly rotatably attached to the rotation fulcrum 24, and this seat plate base 36 is always in contact with the end surface 18a of the upper bracket 18 under its own weight. Also, this seat plate base 3
A pair of left and right guide rails 37 are provided substantially horizontally on the top of the guide rail 6 .

According to this angle changing mechanism 22, the angle adjusting plate 23 is oscillated relative to the upper bracket 18 in the directions of arrows f and f' with respect to the upper bracket 18 by the driving means 25. An upright position θ ₁ in which the back plates 3 and 4 are erected at a predetermined angle with respect to the seat plate 2 in a substantially flush state as shown in FIG. 3A by means of the angle adjustment plate 23;
The upper back plate 4 is oscillated in the directions of arrows b and b' between a rear tilt position θ 2 and a rear tilt position θ ₂ where the upper back plate 4 is tilted rearward at a predetermined angle (approximately 15 degrees) with respect to the seat plate 2 as shown in FIG. 3C. can do.

At this time, at the same time as the angle adjustment plate 23 swings in the direction of arrow b or b', the back plate base 27 on the upper side is moved in the direction of arrow f or It is driven to move in the direction of arrow f'. Accordingly, the back plates 3, 4 are tilted backward in the direction of arrow b and simultaneously moved in the direction of arrow f from the upright position of FIG. 3A to the rearward tilted position of FIG. 3C. At this time, when the upper back plate base 27 is driven to move in the direction of the arrow f while being guided by the guide mechanism 29 by the back and forth movement mechanism, the third A
As shown in the figure, initially, the lower back plate base 26 is moved on both rollers 34 in the direction of arrow f. Then, as shown in FIGS. 3B and 3C, the back plate base 26 rides on both guide rails 37 of the seat plate base 36 by both guide rollers 35, and the back plate base 27 is attached to the back plate base 26. Both guide rails 3 are rotated about the rotation fulcrum 28 in the direction of arrow g.

As shown in Figure C, the back plate 3 on the tip side (lower end side) is moved forward in the direction of arrow c to a position above the seat plate 2, and the back plate 3 finally becomes almost horizontal.

The pair of left and right crotch supports 5 and elbow supports 6 shown in FIGS. 1A to 2C are attached to a pair of left and right substantially L-shaped double-sided frames 38 fixed to both left and right sides of the back plate base 26. These crotch supports 5 and elbow supports 6 are moved integrally with the back plate base 26 via the frames 38 on both sides.

By tilting the back plates 3 and 4 backward in the direction of arrow b, the patient's body position is adjusted from the vertical sitting position to the horizontal position, and by moving the back plate 3 forward in the direction of arrow c. Then, the patient's seat (examination area), which has been adjusted to a horizontal position, is brought closer to the doctor through the curtain.

In addition, when a patient develops anemia during a medical examination, as shown in FIG. 3D, the driving means 25 moves the back plate 4 together with the angle adjusting plate 23 around the rotational fulcrum 24 to the depression angle position θ ₃ as shown in FIG. Tilt backward in direction b. At this time, when the back plate 4 is in a horizontal state where it is almost flush with the back plate 3, the angle adjustment plate 2
3 comes into contact with the seat plate base 36, and thereafter, by tilting the angle adjustment plate 23 backward in the direction of the arrow b, the back plate 3 and the back plate 4 integrally rotate as a pivot point via the seat plate base 36. Arrow b centered on 24
is swung in the direction.

And it can be quickly moved in the direction of arrow f at twice the speed of the second fluid pressure cylinders 42 and 47. Note that when the back plate 4 is moved back in the direction of arrow f', pressure oil is supplied into the pressure oil chamber 55a of the first fluid pressure cylinder 47 through the oil supply and drainage pipe 58, and the oil supply and drainage pipe 57, the pressure oil in the pressure oil chamber 54a of the second fluid pressure cylinder 42 is discharged.

Therefore, according to this back-and-forth movement mechanism (double speed drive device) 41, in the case of emergency bleeding of a patient, etc., the back plate 4 can be quickly moved in the direction of the arrow f, and the patient's body position can be changed from a vertical position in a sitting position to a backward tilt. It can be quickly adjusted to horizontal position, etc. In addition, the first and second fluid pressure cylinders 4
Since the length of each of the first and second fluid pressure cylinders 42, 47 is approximately 1/2 of the moving distance of the back plate 4 in the directions of the arrows f and f',
can be stored compactly between the angle adjustment plate 23 and the back plate base 27.

G _5Next , as shown in Fig. 5A and Fig. 5B,

Next, as shown in FIG. 1B, when the patient's body position is adjusted to the horizontal position of the sitting posture by raising the placing part 1 to the raised position and tilting it backward, both elbow supports 6 are placed at one point as shown in FIG. 1B. It stands up almost vertically as shown by the chain line. Therefore, as shown in FIG. 10B, push the lock release pin 101 a little in the direction of arrow k to release the lock pin 99 from the spring 10.
0 completely into the hole 97 to release the lock of the tilting shaft 94, and then insert the elbow rest 6 into the tilting shaft 9 together with the mounting arm 103 and the tilting shaft 94.
4, rotate the mounting arm 103 by approximately 90 degrees in the direction of arrow l toward the outside of the mounting section ₁ from the position indicated by the solid line to the position indicated by the dashed-dotted line in FIGS. 9 and 10B. It is brought into contact with the rotation stopper 104. Then, as shown in FIG. 1B, the elbow rests 6 are laid down on both left and right sides of the placing portion 1 in a substantially V-shape and in a substantially horizontal position, with the upper limb platform surfaces 88 of the elbow rests 6 facing upward. At this point, both elbow rests 6 are changed into arm rests.

Therefore, both upper limbs of the patient whose body position has been adjusted to the horizontal position of a sitting posture on the mounting part 1 can be stably placed almost horizontally on the upper limb platform 88 of the both elbow supports 6, and the patient's emergency blood transfusion can be carried out. etc. can be done quickly.

Note that when the elbow rests 6 are rotated together with the mounting arm 103 and the tilting shaft 94 in the direction of arrow L' and returned to their original positions, the lock pins 99 are released by the springs 10.
0 automatically returns to the locked state shown in FIG. 10A, and is automatically locked the moment both elbow rests 6 return to their original positions.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various effective changes can be made based on the technical idea of the present invention.

H Effects of the Invention Since the present invention is configured as described above,
This produces the following effects.

In addition to being able to move the waste water receiver automatically, the waste water receiver can also be pushed back freely by hand, allowing the doctor to quickly change the position of the waste water receiver by hand as necessary. Therefore, in the case of a doctor who does not clean the examination area of a patient during a medical examination, it is convenient to be able to quickly push the wastewater receiver, which has been automatically pulled out to the pulled-out position, back by hand to a position where it will not interfere with the examination or medical treatment. It is.

In addition, by manually pushing back the wastewater receiver that has been automatically pulled out to the drawer position, the position of the wastewater receiver can be freely changed as needed, so the wastewater receiver can always be adjusted to the optimal position according to the doctor's height, etc. You can wash the patient in the optimal position.

In particular, when the receiver starts moving in order to have the patient on the receiver assume a posture for examination, etc., the sewage receptacle stored under the receiver is automatically pulled out, so that doctors, etc. There is no need to touch the dirty water receptacle with your hands as much as possible. Since the wastewater receiver is frictionally engaged with the movable member that is automatically pulled out from the storage position to the drawn-out position via the frictional engagement means, the wastewater receiver may become an obstacle for doctors, etc. during the automatic withdrawal of the wastewater receiver. When it comes into contact with an object, the frictional engagement means is caused to slip against the moving member, so that the wastewater receiver can be safely stopped at the position where it comes into contact with the obstacle. Moreover, even though the waste water receiver is automatically pulled out, the waste water receiver can be pushed back by hand as needed, which is convenient for colposcopy.
