B. Summary of the Invention The present invention, as shown in FIGS. 6A to 8, makes it possible to automatically move the wastewater receiver of a medical table and also to freely push back the wastewater receiver by hand. This allows the doctor to quickly change the position of the wastewater receptacle by hand as needed.

C. Prior Art Conventionally, as an examination table for obstetrics and gynecology, for example, Japanese Patent Application Laid-Open No. 63-2
No. 86155 is known.

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 while still sitting by tilting the back board backward. The sewage receptacle, which is linked to the plate via a link mechanism, is configured to be automatically pulled out from the storage position to the pull-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 back the sewage tray freely by hand. Furthermore, the drawer position of the wastewater receptacle is always constant.

However, when a patient is examined, the doctor may or may not wash the patient's examination area, and if the patient is not cleaned, the sewage receptacle pulled out to the drawer position may become an obstacle for the examination or other purposes. There was a problem.

Furthermore, if the drawer position of the wastewater receiver is always the same, there is a problem in that the wastewater receiver becomes an obstacle for medical examinations and other purposes due to height differences among doctors.

SUMMARY OF THE INVENTION An object of the present invention is to provide a wastewater receiving device for a medical table in which the wastewater receiver can be moved automatically and also be pushed back freely by hand.

E! Means for Solving Problem i In order to achieve the above object, the sewage receiving device for a medical table of the present invention includes a moving member that is automatically reciprocated by a driving means, and a frictional engagement means for the moving member. A wastewater receptacle is slidably and frictionally engaged therebetween.

F. Function In the sewage receiving device for a medical table configured as described above, when the moving member is moved by the driving means, the sewage receiving device is automatically pulled out from the storage position to the drawn-out position.

When the sewage tray that has been pulled out to the drawn-out position is pushed by hand, the sewage tray slides against the moving member against the frictional engagement by the frictional engagement means, so the sewage tray can be freely moved by hand. Can be pushed back.

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.

Gl 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 projections and receivers 5, a light emitting light 6 which also serves as an arm table, and the like. 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. 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 lowered to the lowered position. At that time, the patient places his buttocks on the seat board 2, leans his lower back and back on the back board 3.4, and spreads his legs apart for both throws.
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.

Further, 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 has all controls 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. This is done using a footsinch (not shown).

G! 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 a lower bracket 12 fixed to a base 7, and a front end side of a parallel link 14 of equal length constituting a 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 intermediate bracket 15 is rotatably attached to the rear end side of the parallel link 14 by the 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 by the rotation fulcrum 17a. It is mounted rotatably in the directions of arrows d and d'. 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 rotation fulcrum 17b. In addition,

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 the arrows a and a' about the pivot point 14a by the first driving means 19. 1 parallel link mechanism 13,
The lower bracket 12 can be oscillated between a lying position where it is laid down almost horizontally on the rear side as shown in Figure A, and an upright position where it is raised forward and upward to a predetermined angle as shown in Figure 2B. At this time, since the first parallel link mechanism 13 performs parallel movement, the placing part 1 can be moved to the second position.
It is possible to move up and down by parallel movement in the directions of arrows a and a' between the lowered position shown in Figure A and the raised position shown in Figure 2B located above and in front of it. Therefore, the seat plate 2 is raised and lowered while always maintaining a substantially horizontal state. Then, the mounting section 1
The patient's seat (
(examination department) 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 portion 1 can be freely adjusted by swinging it in the vertical directions of arrows d and d' about the pivot point 17a. At this time, since the second parallel link mechanism 16 performs parallel movement, the patient's seat on the placement unit 1 (
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.

G. Next, according to FIGS. 3A to 3D, the back plate 3.4
The 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.
It is mounted rotatably in the b' direction. A drive 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 3I 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
Each pair of guide boos ``J32.33'' is rotatably attached to the 7. 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 f'', and the back plate base 2 is movable with respect to the slider 30.
7 is parallel to the guide shaft 31 and the guide pulley 33 by the arrow f,! It is configured to be movable in the ' direction. In addition, a pair of rollers 34 are attached to both left and right ends of the rotation fulcrum 24,
A pair of left and right guide rollers 35 are provided at the lower end of the back plate base 26.
is installed. 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. Furthermore, a pair of left and right guide rails 37 are provided substantially horizontally on the seat plate base 36.

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 means 25, the angle adjusting plate 23 As shown in FIG. 3A, the back plate 3.4 is raised at a predetermined angle with respect to the seat plate 2 in a substantially flush state, and the upper back plate 4 is placed at the 3rd C position.
A predetermined angle (about 15°) to the seat plate 2 as shown in the figure.
It can be driven to swing in the directions of arrows A and b' between the rearward tilted position θ2 and the rearward tilted position θ2.

Simultaneously with the swinging in the direction, the upper back plate base 27 is driven to move in the direction of the arrow f or the direction of the arrow f' with respect to the angle adjustment vi23 by a back and forth movement mechanism described later. Therefore,
The back plate 3.4 is simultaneously moved in the direction of arrow f while being tilted rearward in the direction of the arrow from the upright position of FIG. 3A to the rearward tilted position of FIG. 3C. At this time, the upper back plate base 27
When the back plate base 26 is driven to move in the direction of the 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 against both rollers 34 as shown in FIG. 3A.
It is moved upward in the direction of arrow f.

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 the arrow mark, the patient's body position is adjusted from the vertical sitting position to the horizontal position, and by moving the back Fi3 forward in the direction of the arrow C, the patient's body position is adjusted to the horizontal position. The adjusted patient's seat (examination area) is brought closer to the doctor through the curtain.

In addition, when a patient develops anemia during a medical examination, the driving means 25 moves the back plate 4 together with the angle adjustment plate 23 in the direction of the arrow to the depression angle position θ3 about the pivot point 24, as shown in FIG. 3D. Tilt back. 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.

Also, a second fluid pressure cylinder 4 configured with a hydraulic cylinder
One end 47a of the cylinder 48 is connected to a bracket 49 that is integrated with the angle adjustment plate 23, and the other end 47b of the piston rod 50 is connected to a bracket 51 that is integrated with the slider 30 that is a connecting member. and pistons 52.53 in cylinders 45.48 and 52.53 respectively.
Of the pressure oil chambers 54a, 54b and 55a, 55b separated by , 54b and 55b are communicated with each other by a flexible pipe 56, and each pressure oil chamber 54a, 55a is connected to an oil supply/drainage pipe 57.
58 are connected.

According to this back-and-forth movement mechanism (double speed drive device) 41, the fourth
As shown in Fig. A, with the back plate 4 being moved back in the direction of the arrow f', pressure oil is supplied into the pressure oil chamber 54a of the first fluid pressure cylinder 42 through the oil supply/drainage pipe 57, and When the pressure oil in the pressure oil chamber 55a of the second fluid pressure cylinder 49 is discharged by the oil drain pipe 58, the piston 52 in the cylinder 45 is moved in the direction of arrow f, as shown in FIG. 4B, and the piston rod 43 is moved. The back plate base 27 is moved in the direction of the 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 arrow f', pressure oil is supplied into the pressure oil chamber 55a of the first fluid pressure cylinder 47 by the oil supply/drainage vibrator 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 and 47 is approximately the length of the movement 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 base 27.

Gs Next, according to FIGS. 5A and 5B, the back plate 3
．． 40 A modification of the forward/backward moving mechanism (double speed drive device) 41 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.
A 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 the same as FIG. A and FIG. 4B. This modification also provides the same effects as in FIGS. 4A and 4B.

G. Next, according to FIGS. 6A to 8, the sewage receiving device 6
1 will be explained.

This sewage receiving device i61 has a pair of endless chains 62 mounted on both left and right sides of a seat plate base 36 so as to be horizontally rotatable via a pair of front and rear sprockets 63 and 64, respectively. Further, a pair of guide shafts 65 are horizontally attached to both left and right sides of the seat plate base 36 along the lower part of both endless chains 62. A portion of both endless chains 62 is fixed with screws 67 or the like to the upper portions of a pair of left and right moving members 66 that are guided by these guide shafts 65 and moved horizontally.

Then, by driving both sprockets 64 forward and backward through a transmission member 69 and a drive shaft 70 by a driving means 68, which is a motor installed in the seat plate base 36, both endless chains 62 are driven. The moving member 66 is configured to be reciprocated along both guide shafts 65 in the directions of arrows c and c', which are the front and rear directions.

On the other hand, a pair of guide grooves 71 having a substantially U-shaped cross section are integrally provided on both left and right sides of the waste water receiver 8 which is horizontally arranged at the lower part of the seat plate base 36. The front ends of both guide grooves 71 are formed as closed ends 71a, and the rear ends are formed as open ends 71b. A pair of left and right frictional engagement means 72 formed in a cylindrical shape or the like by eaves of synthetic resin are horizontally attached to a bracket 73 fixed to the lower part of the removable member 66 by means of a mounting shaft 74, and these two frictional engagement means Means 72 are slidably and frictionally engaged in both id grooves 71 of the waste water receiver 8 . In addition, a pair of left and right stop levers 75
are attached to the side surfaces of both brackets 73 so as to be rotatable in the up and down directions, i.e., the directions indicated by the arrows ``h'' and 76 about the rotational fulcrum 76. Both of these stop levers 75 are biased to rotate in the directions indicated by the arrows by their own weight. The knob 75a at the front end thereof is configured to engage with a protrusion 77 integrally provided at the lower part of the rear ends of both guide grooves 71 at a position where the knob 75a at the front end comes into contact with the lower part of the removable member 66.

According to this sewage receiving device 61, as described above, when the placing part l is raised from the lowered position to the raised position, or by the driving means 6β which is activated by an arbitrary switch operation by the doctor, both When the endless chain 62 is driven to move the re-moving member 66 forward in the direction of arrow C from the backward movement position shown by the dashed line in FIG. 6A to the forward movement position shown by the solid line, Then, the wastewater receiver 8 is automatically pulled out in the direction of arrow C from the stored position shown by the dashed line in FIG. 6A to the pulled out position at the lower front of the seat plate 2 (not shown by the solid line).

However, as shown in FIG. 6B, when the doctor pushes the front surface 8a of the waste water receptacle 8- pulled out to the pulled-out position by hand in the direction of the arrow C' force as necessary, both frictions in the id grooves 71 occur. Resisting the frictional engagement force of the anchoring means 72, move the waste water receiver 8 to the re-moving member 66 (with the re-moving member 66 stopped at the forward movement position) and move the waste water receiver 8 to an arbitrary position in the direction of arrow C' force. You can freely and quickly push it back with your hands.

Therefore, when a patient's examination area is not cleaned during a medical examination or when the wastewater receiver 8 becomes an obstacle to the examination or medical treatment, the doctor can freely push back the wastewater receiver 8 automatically pulled out to the drawer position by hand as necessary. Therefore, the position of the waste water 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. When the sewage receiver 8 is pulled in the direction of arrow C, the frictional engagement means 72 is moved to the open end 71b at the rear end of the guide groove 71.
It can be easily removed from.

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

This sewage scattering prevention device 81 is similar to the sewage receiving device 61 described above.
The sewage scattering prevention plate 9 placed on the upper part of the sewage receiver 8 is attached to the removable member 66 so as to be rotatable in the up and down directions of arrows 1 and i' using a pivot point 82 that is a hinge, and is biased by a torsion spring. The means 83 biases the sewage scattering prevention plate 9 to rotate about the rotation fulcrum 82 in the direction of the arrow 1.

According to this sewage scattering prevention device 81, when the re-moving member 66 is moved back to the return position as shown by the dashed line in FIG. 6A, the sewage scattering prevention plate 9 resists the urging means 83. It is rotated in the direction of arrow i' and stored in a substantially horizontal position at the bottom of the seat plate base 36.

As described above, when the re-moving member 66 is moved forward in the direction of arrow C from the backward movement position indicated by the dashed line in FIG. 6A to the forward movement position indicated by the solid line in FIG. 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 in the upper position, is completely covered from the front, and this vertically erected sewage scattering prevention plate 9 prevents sewage from spilling onto the patient when cleaning the patient's examination area. It prevents the liquid from scattering below the seat (examination section) of the machine, and also functions as a blinding plate under the seat.

According to this sewage scattering prevention plate 81, the back plate 3.4
The wastewater receiver 8 and the wastewater scattering prevention plate 9 can be pulled out together by the re-moving member 66 that can be driven by the drive means 68 regardless of the backward tilting, etc. The sewage scattering prevention plate 9 can be freely put in and taken out together.
