B. Summary of the Invention The present invention provides a medical table having a seat plate and a back plate whose angle can be adjusted with respect to the seat plate.
One of the auxiliary boards is pulled out from under the seat board to the front of the seat board, and the height is adjusted relative to the seat board, and the two auxiliary boards are simultaneously pulled out from under the seat board to the front of the seat board. By arranging them in series in front of the seat plate at almost the same height as the patient, it is possible to allow the patient to take a stable position from a sitting position to a supine position, and also to allow doctors to perform examinations, treatment, and assistance. It is designed to make it easier to do the following.

C. Conventional technology A conventional delivery table has a seat plate, a back plate whose angle can be adjusted with respect to the seat plate, and a single long auxiliary table stored under the seat plate. The auxiliary table is stored under the seat plate, and the angle of the back plate is adjusted to allow the patient to take the optimal sitting posture.When giving birth on the back, the auxiliary table can be pulled out in front of the seat plate and the back plate and seat can be adjusted. There is one in which the board and the auxiliary stand are set on the same horizontal plane.

D Problems to be Solved by the Invention However, in this conventional delivery table, one long auxiliary table was taken in and out from under the seat plate, so the entire long auxiliary table was completely removed from under the seat plate. The structure is such that the height of the auxiliary table cannot be adjusted unless the auxiliary table is pulled out to an appropriate length. There was nothing I could do.

On the other hand, during sitting delivery, the delivered fetus is placed on an auxiliary table and the cord is treated (cutting the cord). It is desirable to adjust the height of the auxiliary table to match the length of the fetal cord.

However, in the past, the height of the auxiliary table had to be adjusted according to the length of each fetus's cord, making it impossible to support each fetus at the optimal height. There was also the problem that it could not be carried out smoothly.

Although it is possible to pull out the auxiliary board to a long length from under the seat board, the present invention adjusts the height of the auxiliary board while the auxiliary board is pulled out to a predetermined length from under the seat board. The aim is to provide a medical table that allows for

E. Means for Solving the Problems In order to achieve the above object, the medical table of the present invention includes two auxiliary plates stored under the seat plate, and one of these two auxiliary plates attached to the seat plate. Pull it out from under the board to the front of the seat board, then adjust the height relative to the seat board, and simultaneously pull out two auxiliary boards from below the seat board so that they are lined up in series with the front of the seat board at a height that is almost flush with the seat board. It is equipped with an auxiliary plate pull-out mechanism for arranging the plate in the shape of the auxiliary plate.

F. Function The medical table configured as described above has two auxiliary plates that are simultaneously pulled out from under the seat plate and arranged in series in front of the seat plate at a height that is almost flush with the seat plate. Although a long drawer is possible, it is possible to adjust the height relative to the seat after only one auxiliary board is pulled out from under the seat to the front of the seat.

G. Example Hereinafter, an example in which the present invention is applied to a delivery table will be described with reference to the drawings.

G1 First, the entire delivery table will be explained with reference to FIGS. 1A to 1C.

This delivery table has an elevating table 2 installed on the upper part of a base 1, and a seat plate 3, a back plate 4, and two auxiliary plates 5, 6 on the upper part of the elevating table 2. The lifting table 2 is vertically adjusted up and down by the lifting table drive mechanism (-U shown in the figure) on the upper part of the base 1, so that the seat plate 3, the back plate 4 and the two auxiliary plates 5.6
The entire structure is height-adjustable. Also,
The seat plate 3 and the back plate 4 are configured so that their angles can be adjusted in the vertical directions of arrows a and a' and in the front and rear directions of arrows S and b', respectively, by a seat plate and back plate drive mechanism described later. The two auxiliary plates 5.6 are moved from the storage position under the seat plate 3 shown by the dashed line in Fig. 1B to Figs. It is configured so that it can be selectively pulled out to a pulled-out position in front of the seat plate 3 shown by a solid line. In addition,
A pair of left and right handles 8, steps (or knee rests) 9, etc. are provided on both sides of the seat plate 3 and at lower positions on both sides.

When giving birth in a seated position, this delivery table allows the patient to take an optimal sitting posture by adjusting the angle of the back plate 4 in the front-rear direction, ie, in the direction of arrows "A" and "B", as shown in FIG. 1A.
Only one auxiliary plate 5 is pulled out from under the seat plate 3 to the front of the seat Fi3 in the direction of arrow C by the slide base 7, and the other auxiliary plate 6 remains stored under the seat plate 3, and one side of the pulled out Arrow d indicates the vertical direction of only the auxiliary plate 5 with respect to the seat plate 3.
, the height can be adjusted in the d' directions. Therefore, when performing belt adjustment with the delivered fetus placed on the auxiliary plate 5 pulled out in front of the seat plate 3 during a sitting delivery, the length of the cord varies depending on each fetus. By adjusting the height of the auxiliary plate 5 in the directions of arrows d and d' according to the height of the auxiliary plate 5, each fetus can be supported by the auxiliary plate 5 at the optimal height for each fetus, making it possible to assist in childbirth and other tasks. Cod band treatment etc. can be performed safely and smoothly.

In addition, this delivery table has two auxiliary plates 5 and 6 placed under the seat plate 3 and in front of the seat plate 3, as shown in FIG. After simultaneously pulling out in the direction of arrow C using the slide table 7, both sleeve support plates 5
．． 6 are simultaneously raised upward in the direction of arrow d, and the support plates 5 and 6 on both sleeves are arranged in series at a height substantially flush with the seat plate 3. If the back plate 4 is horizontally tilted in the direction of arrow b', it becomes a horizontal vent for supine posture.

When this delivery table is not in use, the back plate 4 is laid down horizontally as shown in Figure 1B, and the two auxiliary plates 5 and 6 are placed under the seat plate 3 as shown by the dashed line in Figure 1B. If it is stored in the force direction of arrow C', the entire delivery table can be folded compactly.

In addition, in the case of an emergency such as when a patient develops anemia during a seated delivery, this delivery table can move the back plate 4 in the direction of arrow b' from the elevation angle state shown by the dashed line in FIG. 1C to the depression angle state shown by the solid line. By simply tilting the seat plate 3 in one step, the seat plate 3 can be rotated together with the back plate 4 in the direction of arrow a from a horizontal state shown by a dashed line in FIG. 1C to an elevated state having the same angle as the back plate 4.

And, this delivery table has arrows a and a on the seat plate 3 and back plate 4.
The angle adjustment in the 'direction and the directions of the arrows 5 and 6', as well as the withdrawal and storage of the two auxiliary plates 5 and 6, are controlled by a controller (not shown).

G2 Next, the auxiliary plate pull-out mechanism 11 will be explained with reference to FIGS. 2A to 4C.

First, the configuration of this auxiliary plate drawer mechanism 11 will be explained.
A slide table 7 is arranged horizontally on the slide table base 12 of the lifting table 2, and a pair of guide shafts I3 are horizontally attached to the slide table 7, and a plurality of guide shafts are rotatably attached on the slide table base 12. Guided by 14,

It is configured to be driven by a slide stand drive mechanism, which will be described later, which is a drive means. Two pantograph mechanisms 16a support two auxiliary plates 5.6 arranged one behind the other in the sliding direction (arrow cXc' direction) on the slide table 7 so as to be movable up and down in the arrow d and d' directions. ,
16b is provided.

Both pantograph mechanisms 16a, 1.6b are each composed of a pair of left and right X-shaped links in which the central portions of a pair of links 17a, 17b and 18a, 18b are connected in an X-shape by pins 19a, 19b. The upper end of one link 17a, 17b and the lower end of the other link 18a, 18b of both X-shaped links are connected to the piers 20a, 20b and 2.

Guide rollers 23a, 23b, and 24 rotatably attached to the lower end of the link 18b and the upper end of the other link 18a, 18b.
Guide rails 25a, 25b, and 24b are fixed to the lower surface of both sleeve support plates 5.6 and the slide base 7, respectively.
It is configured to be movable in the directions of arrows c and c' along arrows 6a and 26b, respectively.

The driven parts 27a and 27b of both pantograph mechanisms 16a and 16b are connected between the pair of left and right guide rails 25a and the two pantograph mechanisms 16a and 16b.
5b, and these two wave drive parts 27a, 27b
The left and right sides of are the roller shafts 2 of the guide rollers 23a and 23b.
8a, 28b and roller shafts 30a, 30b of other guide rollers 29a, 29b configured to be movable in directions of arrows c, c' along guide rails 25a, 25b.

The base of the cylinder 32a of the hydraulic cylinder 32, which is the second driving means, is connected to the slide base 7 by the bracket 33.
The tip of the piston rod 32b is fixed to the driven part 27a of one pantograph mechanism 26a by a pin 34.
It is connected to a bracket 35 fixed to.

The driven portion 27 of the other pantograph mechanism 26b
b is provided with a connecting means 38 consisting of a rotary arm rotatably attached in six directions indicated by the arrow e around a rotational fulcrum 37, and a groove-shaped locking portion 39 provided at the tip of this connecting means 38 is provided. Driven part 27a of one pantograph mechanism 16a
The arrows e and e'
It is configured so that it can be locked and removed from any direction. and,
A separation means 41 consisting of a substantially chevron-shaped cam-like protrusion is fixed in the middle of the slide direction (arrow c, c' direction) of the slide table 7, and a separation means 41 is fixed to the slide table 7 in the sliding direction (arrow c, c' direction). The contact means 42 is configured to be able to contact the separation means 41.

Next, the operation of this auxiliary plate pull-out mechanism 11 will be explained.

First, FIG. 4A shows the retracted state of both sleeve auxiliary plates 5.6, and the piston rod 32b of the hydraulic cylinder 32 is in the third position.
By being pulled in the direction of arrow C' in the figure, both wave drive parts 27a and 27b of both pantograph mechanisms 16a and 16b are
are connected by the connecting means 38 and at the same time arrow C
'' direction, and both pantograph mechanisms 163.16b are folded in the arrow d' force direction.In this state, the slide table 7 is pulled in the arrow C'' direction by the slide table drive mechanism described later, and both pantograph mechanisms 163.16b are folded in the arrow d' direction. A plate 5.6 is stored under the seat plate 3.

Next, FIG. 4B shows a state in which only one auxiliary plate 5 is pulled out in front of the seat plate 3.

In this case, the slide table drive mechanism described later slides the slide table 7 from below the seat plate 3 in the direction of arrow C by about two strokes, and only one auxiliary plate 5 is shown by the dashed line. It is stopped at the position where the seat plate 3 is pulled out in front. At this time, as shown in FIG. 2A, the contact means 42 of the connecting means 38 rides on the separating means 41, and the connecting means 38 is rotated in the direction of arrow e about the pivot point 37.
The locking part 39 is disengaged above the engaging part 40, and the driven part 27b of the other bank graphing mechanism 16b is separated from the driven part 27a of the one bank graphing machine tfI 16a. Therefore, when the piston rod 32b of the hydraulic cylinder 32 is pushed out in the direction of arrow C in FIG. As a result, only one auxiliary plate 5 is pushed up in the direction of arrow d as shown by the solid line. Therefore, by controlling the movement of the piston rod 32a of the hydraulic cylinder 32 in the directions of arrows c and c' in FIG. 5 can be adjusted in height with respect to the seat plate 3 in the directions of arrows d and d'.

Next, Fig. 4C shows that the two auxiliary plates 5.6 are seated at the same time
x 3 is shown pulled out to the front.

In this case, the slide table 7 is slid from below the seat plate 3 by the entire stroke in the direction of arrow C using a slide table drive mechanism to be described later, and the two auxiliary plates 5.6 are pulled out in front of the seat plate 3. At this time, in the middle of sliding the slide base 7, the contact means 42 of the connecting means 38 rides on the separating means 41, and the connecting means 38 is once rotated in the direction of arrow e in FIG. 2B, but the slide base 7 As a result of the sliding in the direction of arrow C, the contact means 42 passes over the separating means 41 in the direction of arrow C, so that the connecting means 38 is rotated back by its own weight in the direction of arrow e' in FIG. 2B. Then, when the slide base 7 is slid in the direction of arrow C by the entire stroke, the second
As shown in FIG. remains connected. Therefore, when the piston rod 32b of the hydraulic cylinder 32 is pushed out in the direction of arrow C in FIG.
Both wave drive parts 27a and 27b of 6b are simultaneously moved in the direction of arrow C while being connected by the connecting means 38, and both pantograph mechanisms 16a and 16b are extended in the direction of arrow d,
Both sleeve support plates 5.6 are simultaneously pushed up in the direction of arrow d. As a result, the support plates 5.6 on both sleeves can be arranged in series at a height substantially flush with the seat plate 3 in front of the seat plate 3, as shown by solid lines.

03 Next, as shown in FIG.
I will explain about it.

This slide table drive mechanism 44 is connected to the slide table base 12.
A fixed rack 45 is fixed to the top, and a slide rack 4 is fixed to the slide base 7 by a plurality of brackets 46.
7 and a pinion 48 that is rolled between these two racks 45 and 47.
and a hydraulic cylinder 50 which is a driving means for rolling the pinion 48. Note that this hydraulic cylinder 50 also serves as a first driving means for driving the slide table 7 in the auxiliary plate drawing mechanism 11. The cylinder 50a of the hydraulic cylinder 50 is connected to a plurality of brackets 51.
A pinion 48 is rotatably attached by a pinion shaft 53 to a holder 52 which is fixed onto the slide base 12 and attached to the tip of the piston rod 50b.

According to this slide table drive mechanism 44, the hydraulic cylinder 5
When the piston rod 50b of No. 0 is pushed out in the direction of arrow C, the pinion 48 of the rank and pinion mechanism 49 moves to the fixed rack 4.
The pinion 48 moves the slide rack 47 and the slide stand 7 integrated with it in the direction of the arrow C (extrusion speed of the piston rod 50b). is moved in the direction of arrow C at twice the speed of . Therefore, by pushing out the piston rod 50b in the direction of arrow C and pulling it in in the direction of arrow e', the slide table 7 moves the two auxiliary plates 5.6 from below the seat plate 3 to the front of the seat plate 3 in the direction of arrow C. It can be quickly pulled out and pulled back in the direction of arrow C. The rank and pinion mechanism 49 includes a pinion 48
Move the slide rack 47 by a distance twice the driving distance of arrow C.
Since it can be slid in the 1C' direction, a hydraulic cylinder 50 with a length twice the slide stroke of the slide table 7 can be used.

04 Next, the seat plate and back plate drive mechanism 55 will be explained with reference to FIGS. 6A and 6B.

First, the configuration of the seat plate and back plate drive mechanism 55 will be explained. A bracket 57 is fixed on a stand 56 fixed on the slide table base 12, and a bracket 57 is fixed on the stand 56 fixed on the slide base 12. A pair of rotating arms 58 fixed to the lower back surface
．． 59 is rotatably attached to a rotation fulcrum 60 supported by a bracket 57, and the seat plate 3 and back plate 4 are rotated about the rotation fulcrum 60 in the up and down directions, arrows a and a', and in the front and rear directions, as shown in the arrows. , b' directions.

The hydraulic cylinder 61, which constitutes a first hydraulic cylinder that rotates the seat plate 3 only in one direction upward, that is, in the direction of arrow a, is configured as a single-acting hydraulic cylinder. That is,
In this hydraulic cylinder 61, a cylinder 61a is connected to a stand 61 by a pin 62, and a tip of a piston rotor 1b is connected to a tip 58a of a substantially L-shaped rotating arm 58 by a pin 63. And the cylinder 61a
Hydraulic pressure is supplied to and discharged from one hydraulic port 61e to one hydraulic chamber 61d provided on one side of the piston 61c.

Further, the hydraulic cylinder 68 constituting the second hydraulic cylinder that rotationally drives the back plate 4 in both the front and rear directions of arrows S and b' is configured as a double-acting two hydraulic cylinder. That is, in this hydraulic cylinder 68, a cylinder 68a is connected to the stand 56 by a pin 69, one end of an intermediate link 71 is connected to the tip of a piston rod 68b by a pin 70, and the other end of an intermediate link 71 is fixed to the lower rear surface of the back plate 4. It is connected to the tip of the rotating bracket 72 by a pin 73. A guide roller 74 rotatably attached to the outer periphery of the pin 70 is guided between a pair of upper and lower guide rails 75 fixed to the stand 56 and moved in the directions of arrows c and c'. . And cylinder 68
Hydraulic pressure is alternately supplied and discharged from two hydraulic inlets and outlets 68f and 68g to a pair of hydraulic chambers 68d and 68e provided on both sides of a piston 68c in a.

Next, the operation of this seat plate and back plate drive mechanism 55 will be explained.

First, as shown in FIG. 6B, when hydraulic pressure is supplied to the hydraulic chamber 61d of the hydraulic cylinder 61 from the hydraulic inlet/outlet 61e and the piston rod 61d is pushed out in the direction of arrow C via the piston 61c, the piston rod 61d is pushed out via the rotary arm 58. The seat plate 3 is pushed up in the direction of arrow a about the pivot point 60. And the sixth
As shown in Fig. A, when the hydraulic pressure in the hydraulic chamber 61d of the hydraulic cylinder 61 is discharged from the hydraulic inlet/outlet 61e, the seat plate 3 moves around the pivot point 60 by the arrow a' due to its own weight and the weight of the patient.
be lowered in the direction.

Next, as shown in FIG. 6A, hydraulic pressure is supplied to one hydraulic chamber 68d of the hydraulic cylinder 68 from one hydraulic inlet/outlet 68f, and the piston rod 68b is supplied via the piston 68c.
When pushed out in the direction of the arrow a', the back plate 4 is rotated in the direction of the arrow about the pivot point 60 via the intermediate link 71 and the rotation bracket 72. Then, as shown in FIG. 6B, when hydraulic pressure is supplied to the other hydraulic chamber 68e of the hydraulic cylinder 68 from the other hydraulic inlet/outlet 68g, the back plate 4 is rotated about the rotation fulcrum 60 in the direction of arrow b'. .

Next, when changing the patient's position from the sitting position to the supine depression angle state during sitting delivery, as shown in Figure 6B,
The hydraulic cylinder 68 rotates the back plate 4 about the rotation fulcrum 60 in the direction of the arrow b', which is the rearward direction, to create a one-stage motion of tilting it all at once from the elevation angle state shown in FIG. 6A to the depression angle state shown in FIG. 6B. conduct.

At this time, from the time when the back plate 4 and the seat plate 3 are almost in the horizontal position, the tip 59a of the rotary arm 59 comes into contact with the lower surface 76 of the seat plate 3 from the direction of arrow b', and The seat plate 3 and the back plate 4 are quickly rotated upward in the direction of arrow a. At that time, the rotating arm 58, which is rotated together with the seat plate 3 in the direction of arrow a, simply pulls the piston rod 61b and piston 61C of the single-acting hydraulic cylinder 61 in the direction of arrow C to release them from the hydraulic chamber 61d. Therefore, without being equally constrained by the hydraulic cylinder 61,
The seat plate 3 is integrated with the back plate 4 by the rotating arm 59 as shown by the arrow a.
It can be rotated smoothly in any direction. Then, by the rotating arm 59, the back plate 4 and the seat plate 3 are rotated in the direction of the arrow A and the direction of the arrow a, with the back plate 4 and the seat plate 3 always connected together in a substantially flush state. There is no chance of the plate 3 accidentally falling over at an angle of depression greater than the elevation angle.

Here, by rotating the back plate 4 in the direction of arrow b',
Although the seat plate 3 is configured to be rotated in the direction of the arrow a by a rotating arm 59 fixed to the back plate 4 side, when the back plate 4 is rotated in the direction of the arrow b', the back plate 4 and the seat plate 3 are rotated. When the state is almost flush, the back plate 4 is brought into contact with the rotating arm 58 fixed to the seat plate 3 side, and the back plate 4 is then rotated in the direction of arrow b'. Rotating arm 58 at 4
The seat plate 3 may be configured to be rotated in the direction of the arrow a through the .

G. Next, the back plate sliding mechanism 78 will be explained with reference to FIGS. 7 and 8.

This back plate sliding mechanism 78, as shown in FIG.
9 and a rotating bracket 72 are fixed to the lower end rear surface of the rotating frame 79, and the rotating bracket 72 is driven by the hydraulic cylinder 68, so that the rotating frame 79
is configured to be rotationally driven in the direction of arrow bSb', which is the front-rear direction, about the seven pivot points at the lower end of the rotary arm 59. The back plate 4 is fitted to the front surface of the rotating frame 79 through a recess 80 provided along the back surface of the back plate 4, and the back plate 4 is moved along the front surface of the rotating frame 79 in the vertical direction indicated by the arrow g. It is attached so that it can slide in the g direction.

At this time, as shown in FIG. A pair of left and right roller bearings 84 are interposed between a pair of left and right guide rails 83 provided on the back surface of the back plate frame 82. Further, a pair of left and right guide frames 8 that are approximately L-shaped are fixed to the back surface of the back plate frame 82.
5 is opposed to a synthetic resin slippery sheet 86 fixed to two surfaces of a pair of left and right columns 79a by adhesive or the like. Therefore, the back plate 4 can slide extremely smoothly in the directions of arrows g and g' with respect to the rotating frame 79 by the roller bearings 84 and the slippery sheet 86, and the back plate 4 can slide against the rotating frame 79 due to its own weight. Arrow g on the downward side
It is biased to slide in the ' direction.

According to this back plate sliding mechanism 78, as shown in FIG.
Adjust the angle of the back plate 4 in the directions of arrows b and b' together with step 9. At this time, since the back plate 4 is constantly urged to slide in the direction of arrow g', which is the lower side of the rotating frame 79, due to its own weight, the lower end front corner 4a of the back plate 4 is aligned with the rear end upper surface of the seat plate 3. The back plate 4 is in constant contact with the corner 3a of the
The angle can be adjusted in the directions of arrows S and b'. That is, when the rotating frame 79 is rotated in the direction indicated by the arrow mark and the lower end 79b of the rotating frame 79 approaches the corner 3a of the seat plate 3, the back plate 4 slides relative to the rotating frame 79 in the direction indicated by the arrow g. , the rotating frame 79 is rotated in the direction of arrow b', and the lower end 79b of the rotating frame 79 is at the corner 3 of the seat plate 3.
When moving away from a, the back plate 4 slides in the direction of arrow g' with respect to the rotating frame 79.

Therefore, without causing the corner 4a of the back plate 4 to approach or separate from the corner 3a of the seat plate 3, both corners 4a
, 3a are always in contact with each other at one location, the angle of the force direction of the back plate 4 can be adjusted as shown by the arrows 3a and 3a. As a result, when the back plate 4 is raised in the direction indicated by the arrow, the corner 4a of the back plate 4 approaches the corner 3a of the seat plate 3 in the direction of the arrow C, and the patient's buttocks are touched by these corners 4a, 3a. There will be no inconveniences such as accidental pinching or pushing out the patient's buttocks in the direction of arrow C at the corners 4a''c of the back plate 4.

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.

For example, in the above embodiment, a hydraulic cylinder is used as a driving means for the auxiliary plate drawing mechanism, but an air cylinder or the like may also be used.

Furthermore, the present invention is not limited to delivery tables, but includes examination tables,
It is widely applicable to various medical tables such as operating tables.

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

Two auxiliary boards are stored under the seat board, and by adjusting the angle of the back board, the patient can take the optimal sitting posture. In addition, two auxiliary plates are pulled out from under the seat plate at the same time and placed in series in front of the seat plate at approximately the same height as the seat plate.
By folding the backboard horizontally, the patient can be placed in a supine position.

However, since it is possible to adjust the height relative to the seat after pulling out only one auxiliary board from below the seat to the front of the seat, for example, during a sitting delivery, it is possible to place the delivered fetus on the auxiliary board. When performing bandage treatment while the fetus is being carried, the height of the auxiliary plate is adjusted to match the length of the sea bream, which varies depending on the fetus, so that each fetus can be placed at the optimal height for each fetus. It can be supported by an auxiliary board, allowing childbirth assistance, love affairs, etc. to be performed safely and smoothly.
