B. Summary of the Invention The present invention, as shown in FIGS. 3A to 3C, maintains the seat plate of a medical table in a substantially horizontal state at all times, while tilting the back plate backward and moving it forward relative to the seat. By moving a part of the back plate to a position above the seat plate, the patient's seat position ( This allows the user to simultaneously move the medical examination section (examination section) closer to the doctor through the curtain and retract the seat board under the backboard.

C. Conventional technology Conventionally, as an examination table for obstetrics and gynecology, for example,
No. 86155 is known.

In this conventional examination table, the seat plate and the back plate are supported by the same support member, and after the patient assumes a vertical sitting position on the seat plate, the back plate is supported integrally with the seat plate by the support member. By tilting, the patient's center of gravity is shifted from the seat board to the back board. At the same time, the patient's seat (examination area) is moved from the seat to the back board while the patient's seat (examination area) is adjusted to a horizontal position with the patient in a sitting position. Get closer to the doctor. Then, the seat plate, which has been raised upward and forward of the patient's seat due to the backward tilt of the back plate, is then moved backward and downward relative to the tip of the back plate, and the seat plate is moved to the lower part of the patient's seat. It is configured to be stored.

D. Problems to be Solved by the Invention However, this conventional examination table requires the following actions: adjusting the patient's body position from a vertical sitting position to a horizontal position leaning backwards, and retracting the seat plate below the back board. must be done in sequence,
These operations take time to complete. Therefore,
There was a problem in that doctors were unable to quickly examine and treat patients in emergencies such as emergency bleeding in patients.

Furthermore, there is a problem in that the mechanism for changing the angle of the back plate and the retracting mechanism for the seat plate must be provided separately, resulting in a complicated structure.

The present invention involves the action of moving the patient's seat closer to the doctor through the curtain while adjusting the patient's body position from a vertical sitting position to a horizontal position leaning backwards, and an action of retracting the seat board under the back board. The purpose is to provide a medical table that can perform both functions at the same time.

E. Means for Solving the Problems In order to achieve the above object, the medical table of the present invention has a seat plate that is maintained in a substantially horizontal state at all times, an angle changeable with respect to the seat plate, and a seat plate that is adjustable with respect to the seat plate. It comprises a back plate supported so as to be movable in the front-rear direction, a mechanism for changing the angle of the back plate, and a mechanism for moving the back plate back and forth, the angle changing mechanism tilting the back plate backward with respect to the seat plate, and The back plate is moved forward with respect to the seat plate by a back and forth movement mechanism, and a part of the back plate is moved to a position above the seat plate.

F. Function The medical table configured as described above maintains the seat board in a nearly horizontal state at all times, while tilting the back board forward relative to the seat, and partially resting the back board on the seat. The seat board is moved to a position above the board, and by moving a part of the back board to a position above the seat board, the seat board is eventually stored at the bottom of the back board. Therefore, while adjusting the patient's body position from a vertical sitting position to a horizontal position leaning backwards, the patient's seat should be moved closer to the doctor through the curtain, and the seat board should be retracted under the back board. Can be done at the same time.

G. Example Hereinafter, an example in which the present invention is applied to an obstetrics and gynecology examination table 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 3.4 divided into upper and lower parts, a pair of left and right throw supports 5, a material support 6 that also serves as an upper limb stand, etc. . These placing parts 1 are supported on the base 7 so as to be movable up and down by a lifting device which will be described later. Note that both back plates 3.4 are supported so as to be able to change their angle and to be movable in the front and back direction relative to the seat plate 2 by an angle changing mechanism and a back and forth moving mechanism that will be described later. 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 should place his buttocks on the seat board 2, lean his waist and back on the back board 3.4, open his legs for both throws, and put his hips on the seat board 2.
Place it on top of you and assume a vertical sitting position with your legs spread.

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. The back plate 3 on the tip side is moved forward in the direction of arrow C while tilting backward in the direction of the arrow C together with the throw tray 5 and the material tray 6.
is moved to a position above the seat plate 2.

Then, due to the backward tilt of the back plate 3.4, the patient's waist and back come to rest almost horizontally on the back plate 3.4, and the patient's center of gravity shifts from above the seat plate 2 to above the back plate 3.4. At the same time, the patient's body position is adjusted to a horizontal position with the legs tilted open. Then, the patient is moved forward in the horizontal position by moving the placing part 1 obliquely forward in the direction of arrow a and moving the back plate 3.4 forward in the direction of arrow C. The seat (examination area) of the patient is brought closer to the doctor through the curtain.

At this time, the back plate 3 is moved to a position above the seat plate 2 in the direction of arrow C, and as a result, the seat plate 2 is stored below the back plate 3 in the opposite direction 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 move from the storage position at the bottom of the seat plate 2 to the seat plate 2.
automatically pulled out to the front drawer position.

This examination table is equipped with all control functions such as raising and lowering the platform 1, changing the angle of the back surface 3.4 with respect to the seat plate 2, moving it back and forth, and putting in and taking out the sewage receiver 8 and the sewage scattering prevention plate 9. - Rolls are performed using a foot switch (not shown).

G2 Next, the elevating device 11 for the placing portion 1 will be explained with reference to FIGS. 2A to 2C.

This elevating device 11 is attached to a lower bracket 12 fixed to the base 7, and the front end side of the parallel link 14 of equal length constituting the first parallel link mechanism 13 is rotated in the directions of arrows a and a'' by a rotation fulcrum 14a. It is installed so that it can move freely.And,
The rear end side of the parallel link 14 or the rotation fulcrum 14. The rear end side of the parallel links 17 of equal length constituting the second parallel link mechanism 16 is rotatably attached to the intermediate bracket 15 rotatably attached to the intermediate bracket 15 by the pivot point 17a in the directions of the arrows d and d'. installed. The mounting portion 1 is attached to an upper bracket 18 to which the front end side of the parallel link 17 is rotatably attached via a pivot point 1'7b.

Note that the first parallel link mechanism 13 is long and the second parallel link mechanism 16 is short. Then, the first parallel link mechanism 13 is connected to the rotation fulcrum 1 with respect to the lower brackets 1 to 12.
The first driving means 19 swings in the directions of arrows a and a' about 4a, and the second parallel link mechanism 16 swings in the directions of arrows d and d about the pivot point 17a relative to the intermediate bracket 7t□15.
A second drive means 2o that swings in the ' direction is separately provided. Incidentally, these first and second driving means are constituted by hydraulic cylinders.

According to this lifting device 11, by swinging the first parallel link mechanism 13 with respect to the lower bracket 12 in the direction of the arrow a1a' about the rotational fulcrum 14a by the first drive means 19, the first parallel The link mechanism 13 is
The lower bracket 12 swings between a lying position where it is laid down almost horizontally on the rear side of the lower bracket 12 as shown in Figure A, and an upright position where it is raised forward and upward from the lying position to a predetermined angle as shown in Figure 2B. Can be driven. At this time, since the first parallel link mechanism 13 performs parallel movement, the placing section 1 is
The lowered position shown in Figure A and the second Blli located above and in front of it.
It can be raised and lowered by parallel movement in the directions of arrows I and a' between the position of the earthen wall shown at J and the position of the earthen wall. Therefore, the seat plate 2 is raised and lowered while always maintaining a substantially horizontal state. and,
By raising the placing part 1 from the lowered position to the raised position diagonally forward in the direction of arrow a, the patient's seat (examination part) on the placing part 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 relative to the intermediate bracket 15 by the second driving means 19, as shown in FIG. 2C. The height of the mounting section 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, the second parallel link mechanism 16 performs a parallel movement, so the patient's seat (
The height of the medical examination section can be adjusted with almost no change in the position of the medical examination section) in the direction of arrow e, which is the front-rear direction.

03 Next, according to FIGS. 3A to 3D, the back plate 3.4
The zero angle changing mechanism 22 will be explained.

This angle changing mechanism 22 has the lower end of the angle adjusting plate 23 pointed at the upper end of the upper bracket 18 by a rotation fulcrum 24.
b' It is attached so that it can rotate freely in the force direction. A driving means 25 is provided for swinging the angle adjustment plate 23 relative to the upper bracket 18 in the direction b' indicated by the arrow 24 about the rotation fulcrum 24.

Note that this driving means 25 is composed of a hydraulic cylinder. In addition, the back plate base 2 of the back plate 3.4 is divided into upper and lower parts.
6.27 are rotatably connected to each other by a rotation fulcrum 28, and the upper back plate 4 is attached to the angle adjustment plate 23 by a guide mechanism 29 so as to be movable in the directions of arrows f and f'. This guide mechanism 29 has a pair of left and right parallel guide shafts 31 attached to a slider 30 disposed between the angle adjustment plate 23 and the back plate base 27, and angle adjustment plates on the outside and inside of each of these parallel guide shafts 31. 23 and back plate base 2
A pair of guide boos IJ32 and 33 rotatably attached to each of the guide boos IJ32 and IJ7 are respectively engaged with each other. Therefore,
The slider 30 is parallel to the guide shaft 3 with respect to the angle adjustment plate 23.
1 and a guide pulley 32 in the directions of arrows f and M.
is configured to be movable in the directions of arrows f and f' by a parallel guide shaft 31 and a guide pulley 33. A pair of rollers 34 is attached to both left and right ends of the rotation fulcrum 24, and a pair of left and right guide rollers 35 is attached to the lower end of the back plate base 26. Further, 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 front surface 18a of the upper bracket 18 under its own weight. Also, this seat 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, by swinging the angle adjusting plate 23 with respect to the upper bracket 18 in the directions of the arrows f and f' about the rotation fulcrum 24 by the driving vJ means 25, the angle adjusting plate 23 is 23, as shown in FIG. 3A, an upright position θ1 where the back plate 3.4 is raised substantially flush with the seat plate 2 at a predetermined angle, and the upper back plate 4 is placed in the third position.
As shown in Figure C, a predetermined angle (approximately 15°
) and the rearward tilted position θ2, it is possible to perform rocking drive in the force directions shown by the arrows (a) and (b').

At this time, the direction of the arrow b' of the angle adjustment plate 23
Simultaneously with the swinging in the direction, the upper back plate header 27 is moved in the direction of the arrow f or the direction of the arrow f' with respect to the angle adjustment plate 23 by a back-and-forth moving mechanism to be described later. Therefore, the back plate 3.4 is moved in the direction of the arrow f while being tilted backwards 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 arrow f while being guided by the guide mechanism 29 by the back and forth moving mechanism, the lower back plate base 26 initially moves on both sides as shown in FIG. 3A. It is moved on the roller 34 in the direction of the arrow.

Then, as shown in FIGS. 3B and 3C, the back plate base 26 is moved to the seat plate base 3 by both guide rollers 35.
6 on both guide rails 37, and the back plate base 27
is centered around the rotational fulcrum 28 with respect to the back plate base 26
While being rotated in this direction, it is pushed forward in the direction of arrow C by both guide rollers 35 on both guide rails 37. As a result, at the same time as the back plate 3.4 tilts backward in the direction of arrow A, the back plate 3 on the tip side (lower end side) moves forward in the direction of arrow C to a position above the seat plate 2, as shown in Fig. 3C. The back plate 3 is moved and finally becomes almost horizontal.

Note that the pair of left and right throw receivers 5 and the material receivers 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 throw receivers 5 and material receivers 6 are moved integrally with the back plate base 26 via the frames 38 on both sides.

Then, by tilting the back plate 3.4 backward in the direction of arrow C, 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, the patient's body position is adjusted to the horizontal position. The patient's seat (examination area) is adjusted to be close to the doctor through the curtain.

In addition, when a patient develops anemia during a medical examination, as shown in FIG. lean back in the direction. At this time, when the back plate 4 is in a horizontal state where it is almost flush with the back plate 3, the front end surface 23a of the angle adjustment plate 23 comes into contact with the seat plate base 36, and from then on, the angle adjustment plate 2
By tilting backward in the direction indicated by the arrow 3, the back plate 3 is swung integrally with the back plate 4 via the seat plate base 36 in the direction indicated by the arrow about the pivot point 24.

04 Next, as shown in FIGS. 4A and 4B, the back plate 3.
The longitudinal movement mechanism (double speed drive device) 41 of No. 4 will be explained.

This back-and-forth moving mechanism (double speed drive device) 41 drives the back plate 4, which is a mounting portion, at double speed in the directions of arrows f and f', which are the front and rear directions, with respect to the angle adjustment plate 23, which is a base.

That is, the first fluid pressure cylinder 4 configured with a hydraulic cylinder
One end 42a of the piston rod 43 is connected to a bracket 44 that is integral with the back plate base 27, and the other end 42b of the piston rod 43 is connected to a bracket 46 that is integral with the slider 30 that is a connecting member.

When the pressure oil in the pressure oil chamber 55a of the second fluid pressure cylinder 49 is discharged by the oil supply/drainage bi 158, the piston 52 in the cylinder 45 is moved in the direction of arrow f, and the piston rod 43 is moved as shown in FIG. 4B. The back plate base 27 is moved in the direction of arrow f. And the first fluid pressure cylinder 4
The pressure oil in the second pressure oil chamber 54b is supplied through the flexible pipe 56 into the pressure oil chamber 55b of the second fluid pressure cylinder 47, and the piston 53 in the cylinder 48 is moved in the direction of the arrow f. Slider 30 via rod 50
is moved in the direction of arrow f. As a result of the above, the first and second
The amounts of movement of the other ends 42b and 47b of the fluid pressure cylinders 42 and 47 are added together by the slider 30, and these other ends 42b and 47b are simultaneously moved in the same direction, ie, the direction of the arrow f. can be quickly moved in the direction of arrow f at twice the speed of the first and second fluid pressure cylinders 42 and 47. Note that when the back plate 4 is moved back in the direction of the 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 pressure oil in the pressure oil chamber 54a of the second fluid pressure cylinder 42 is discharged by the oil supply/drainage pipe 57.

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 sitting position to a backward leaning position. It can be quickly adjusted to a horizontal position. Furthermore, since the length of each of the first and second fluid pressure cylinders 42, 47 is approximately twice the moving distance of the back plate 4 in the directions of arrows f and f', these first and second fluid pressure cylinders 42.47
can be stored compactly between the angle adjustment plate 23 and the back plate heath 27.

G. Next, according to FIGS. 5A and 5B, the back plate 3.
A modification of the forward/backward movement mechanism (double speed drive device) 41 of No. 4 will be described.

This modification includes a cylinder 45 which is the other end 42b of the first fluid pressure cylinder 42, and a cylinder 45 which is the other end 42b of the second fluid pressure cylinder 47.
The connecting member 59 is connected to the tip of the piston rod 50 which is 7b.
The other structures are connected directly by the fourth
It is similar to the Δ diagram and FIG. 4B. This modification also provides the same effects as in FIGS. 4A and 4B.

Gb Next, the first water receiving device 61 will be explained with reference to FIGS. G to 8.

This sewage receiving device 61 has a pair of endless chains 62 on both left and right sides of a seat plate header 36, which are horizontally rotatable through a pair of front and rear sprockets 63 and 64, respectively. In addition, a pair of guide shafts 65 are horizontally attached to the left and right sides (111) of the seat plate header 36 along the lower part of the endless chain 62. A part of the endless chain 62 is fixed to the upper part of the pair of left and right moving members 66 using screws 67, etc. The transmission member 69 and Drive shaft 7
By driving both sprockets 64 in forward and reverse rotation through 0, both endless chains 62 are driven, and the circular moving member 6

It is configured to be driven back and forth in the c' direction.

On the other hand, a pair of guides I" having a substantially U-shaped cross section are located on both the left and right sides of the waste water receiver 8, which is arranged horizontally at the bottom of the seat plate base 36.
A groove 71 is integrally provided. Both guide grooves 71
The front end is formed as a closed end 71a, and the rear end is formed as an open end 71b.
is formed. Then, i'1. A pair of left and right frictional engagement means 72 are horizontally attached to a bracket 73 fixed to the lower part of the circular moving member 6G by means of a shaft 74. are slidably and frictionally engaged relative to each other. In addition, a pair of left and right slide levers 75 are attached to rotational fulcrums 76 on the sides of both brackets 73.

According to this sewage receiving device 61, as mentioned above, at the same time as the placing part 1 is raised from the lowered position to the raised position,
Alternatively, in six days, the driving means operated by the doctor's arbitrary switch operation drives both endless chains 62 to move the circular moving member 66 from the backward movement position shown by the dashed line in FIG. 6A to the position shown by the solid line. When it is moved forward in the direction of arrow C to the moving position, the sewage receiver 8 is moved via both frictional engagement means 72 from the storage position shown by the dashed line in FIG. It is automatically pulled out in the direction of arrow C.

However, as shown in FIG. 6B, when the doctor manually pushes the front surface 8a of the wastewater receptacle 8 that has been pulled out to the pulled-out position in the direction of arrow C', both frictional engagements within the side guide groove 71 occur. The sewage receiver 8 is moved circularly by the member 6 against the frictional engagement force of the coupling means 72.
6 (with the circular moving member 66 stopped at the forward movement position), the wastewater receiver 8 can be freely and quickly pushed back by hand to any desired position in the direction of arrow C'.

Therefore, when a patient's examination area is not cleaned during a medical examination, or when the wastewater receiver 8 interferes with the examination or medical treatment, the doctor can freely use the wastewater receiver 8 automatically pulled out to the drawer position by hand as necessary. By pushing it back, the position of the wastewater receiver 8 can be quickly changed by hand.

Note that when pulling out the sewage receiver 8 that has been pulled out to the pulled-out position shown by the solid line in FIG. ' direction and remove it above both protrusions 77. By pulling the waste water receiver 8 in the direction of arrow C, both frictional engagement means 72 are moved to the open end 71b at the rear end of both guide grooves 71.
It can be easily removed from.

G7 Next, the sewage scattering prevention device 81 will be explained with reference to FIGS. 6A and 6B.

The plate 9 can be pulled out together in the direction of arrow C from the storage position indicated by the dashed-dotted line to the pulled-out position indicated by the solid line in FIG. 6A. At this time, the sewage scattering prevention plate 9 is pulled out in front of the seat plate base 36 and moved upward around the pivot point 83 by the biasing means 83 along the corner portion 36a at the lower front end of the seat plate base 36. It is rotated in a certain arrow i direction and gradually stands up. As shown by the solid line in FIG. 6A, when this sewage scattering prevention plate 9 is completely pulled out to the drawn-out position, it stands up almost vertically above the sewage receiver 8, and as described above, the sewage scattering prevention plate 9 The lower part of the back plate 3 which is pulled out almost horizontally to the upper position is completely covered from the front. A prevention plate 9 is attached to this vertically erected sewage splash 11 to prevent sewage from splashing below the patient's seat (examination area) when cleaning the patient's examination area, and to prevent the sewage from splashing below the patient's seat (examination area). Acts as a blindfold for subordinates.

According to this sewage scattering prevention plate 81, the back plate 3.4
The waste water receiver 8 and lη water splash prevention plate 9 can be pulled out together by the removable member 66 that can be driven by the drive means 68 regardless of backward tilting, etc., so that the doctor can

A mounting arm 103 fixed to the rear end of the material receiver 6 and bent in a substantially U-shape is fixed to the lower end surface 94a of the inclined shaft 94. A hole 97 with an axis P perpendicular to the axis P2 is provided in a part of the side surface of the inclined shaft 94, and a hole 98 with the same axis P2 and the same diameter as this hole 97 is provided in the mounting base 90. ing. And hole 9
A lock pin 99 and a spring 100 are inserted into hole 9 .
8, a lock release bin 101 is inserted which is movable in the direction indicated by the arrow. Note that the lock pin 99 is moved by the spring 100 from the direction of the arrow ' to the lock release pin 101.
A retaining ring 102 is attached to the lock release pin 101, which prevents the lock release pin 101 from coming off in the direction of the arrow ''.

Furthermore, a rotation stopper 104 for the mounting arm 103 is provided at the lower part of the mounting base 90.

According to this material receiving device 86, first, as shown in FIG. 1A, when the placing part 1 is lowered to the lowered position, the material receiving surfaces 87 of the both armrest lights 6 are locked upward and at the substantially horizontal upper end. ing. At this time, as shown in FIG. 10A, the lock pin 99 is fitted across both holes 97 and 98, and the inclined shaft 94 is locked with the lock pin 99.

Therefore, as described above, the patient who is in a vertical sitting position on the placement part 1 can stably place both elbows on the material receiving surfaces 87 of the elbow lights 6.

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 unit 1 to the raised position and tilting it backwards, the beams 6 on both elbows are adjusted to the position shown in FIG. 1B. The lock release pin 101 is pushed slightly in the direction of the arrow to completely push the lock pin 99 into the hole 97 against the spring 100, as shown in FIG. After unlocking the tilting shaft 94, push the material receiver 6 into the mounting arm 103 and the tilting shaft 94 together with the tilting shaft 94.
4. Rotate the mounting arm 103 by approximately 90° 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. It is brought into contact with the stopper 104. Then, as shown in FIG. 1B, the elbow lights 6 are laid down on both left and right sides of the placement part 1 in a substantially V-shape, and the upper limb platform 8 of the elbow lights 6 is lowered.
8 is turned upward and almost horizontally, and at this point,
Change both elbow lights 6 into upper limb stands.

Therefore, both upper limbs of a patient whose body position has been adjusted to the horizontal position of a sitting position on the placing unit 1 can be stably placed almost horizontally on the upper limb table 88 of the both elbow lights 6, and emergency blood transfusion of the patient can be performed. can be done quickly.

Note that when the elbow light 6 is rotated together with the mounting arm 103 and the tilting shaft 94 in the direction of arrow β' and returned to its original position, the lock pin 99 is automatically moved to the locked state shown in FIG. 10A by the spring 100. The moment the both elbow lights 6 return to their original positions, they are automatically locked.

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, it produces the following effects.

While adjusting the patient's body position from a vertical sitting position to a horizontal position leaning backwards, the patient's seat can be moved closer to the doctor through the curtain, and the seat board can be retracted under the back board at the same time. Therefore, the time required for these series of operations can be significantly shortened. Therefore, even in the event of an emergency such as emergency bleeding of a patient, a doctor can quickly perform examinations and treatment.

Since it is sufficient to move only the back plate while keeping the seat plate fixed, there is no need for a storage mechanism for the seat plate, making the structure extremely simple.
