Abstract

PURPOSE:To set a pregnant woman at an easy posture by allowing a thigh receiving part to be tilted and installing a flat plate-shaped leg supporting board so as to be sent out forward from directly under a shoulder plate over an elevation board and installing a tray under the supporting board so as to be pulled out forwardly in a horizontal state. CONSTITUTION:When the processes in the first parturition period before birth and after birth are observed, the thigh receiving part 4 is retreated downward in inclination, and a leg supporting board 5 is pulled forward, and set in nearly continuous to a shoulder plate 2. Since, in this state the thigh receiving part 4 does not project over the side part of the leg supporting board 5, no obstruction exists in the shift of a pregnant woman between other beds and taking an easy posture. In parturition, the leg supporting board 5 is accommodated into an elevation board 1, and the thigh receiving part 4 is turned upward, and the thigh of the pregnant woman is held in a spread state. Further, the soles of the feet of the pregnant woman are supported by the foot receiving parts 7 and 7, and a shoulder plate 2 is erected at a proper angle, and a tray 6 is pulled out under the buttocks receiving part 3, and the birth posture is adjusted. Therefore, the pregnant woman can take an easy posture.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement in a seated delivery table used in obstetrics and gynecology.

(Prior Art) Recently, it has been considered reasonable to give birth in a sitting position because it causes less stress on the mother's body, and a delivery table specifically for this has been developed and put into practical use. The seated delivery table includes an elevating table, a back plate provided on the elevating table so as to be tiltable back and forth, a buttock holder pivotally connected to the front end of the back plate, and both sides of the buttock holder. The basic structure includes a thigh support placed in a split-leg configuration, and is equipped with a fetal support tray, a foot support, a hand grip, and the like.

Here, the main points of obstetric medical care using the above-mentioned sitting delivery table will be briefly described. When a pregnant woman is in the delivery stage, the buttock support and thigh support are removed and an auxiliary bed is connected to the front end of the back plate.

The pregnant woman puts her feet on this auxiliary bed and waits in a comfortable position, such as supine, lateral, or sitting. When the delivery period begins, the auxiliary bed is removed, the buttock support and thigh support are reattached, the back plate is erected, and the fetus is delivered into the tray placed under the buttock support. After delivery, the auxiliary bed is connected in the manner described above, the pregnant woman is placed in a comfortable position, and the progress of the pregnancy is monitored.

(Problem to be Solved by the Invention) However, in the case of using the above-mentioned seated delivery table, in order to allow the pregnant woman to take a comfortable position before and after delivery, its functionality requires the connection and removal of the auxiliary bed, the buttock support, and the thigh support. Troublesome work such as removing and installing the bearing is unavoidable. In addition, there is a lack of quick response in case of emergency, and furthermore, it is necessary to secure a permanent place for an auxiliary bed or a temporary storage place for the removed buttock and thigh supports, which causes the delivery room to become cluttered. It was inevitable. For this reason, a delivery table has also been developed which is equipped with a cuff table inside the elevating table, and when in use, it is pulled forward and raised further so that it is connected to the back plate. However, in this case, a complicated mechanism is required for sending out, feeding in, and pushing up the leg support, so the device becomes large-scale and heavy. In addition, since the thigh supports remain as they are on the left and right sides of the bed, they get in the way when moving from one bed to another or when taking a comfortable posture on top of the bed. . Furthermore, since the fetal receiving tray is generally fixedly provided below the buttock receiving tray, it may get in the way when a pregnant woman gets on and off or when the surgeon examines the patient.The present invention was made in view of the above. To provide a new seated delivery table which is equipped with a calving table so as to be able to be sent forward and backward, and which is retracted below the thigh hair receiver when the calving table is sent out, and which also has a tray that can be pulled out. This is what I am trying to do.

(Means for Solving the Problems) The configuration of the sitting delivery table of the present invention that achieves the above object will be explained based on the attached drawings. Figure 2 is a side view showing an example of the sitting delivery table of the present invention, Figure 2 is a plan view of the same, Figure 3 is a side view showing an example of its use, and Figure 4 is the rV-IV line of Figure 2. Figure 5 is a cross-sectional view taken along the line V-V of Figure 2, and Figure 6 is a cross-sectional view of Figure 3.
7 is a diagram similar to FIG. 3 showing another usage example, FIGS. 8 and 9 are a plan view and a longitudinal sectional view for explaining the main drive mechanism, and FIG. FIG. 11 is an explanatory view of the main part showing the rotation mechanism of the thigh support, FIG. 12 is a cutaway plan view of the same part, and FIG. FIG. 14 is an explanatory view of the main part showing another rotation mechanism, FIG. 14 is an explanatory view of the main part combining the rotation mechanisms of FIGS. 13, 11, and 12, and FIG. 15 is a plan view of the same.

That is, the sitting delivery table of the present invention includes a lifting table 1 and a lifting table 1.
A back plate 2 that is tiltably mounted on the top, a buttock support 3 disposed at the front of the back plate 2, and thigh supports disposed in a split-leg shape on both sides of the buttock support 3. 4, the thigh support 4 is tiltable, and above the elevating table 1, a flat plate-like pedestal table 5 is sent forward from directly below the back plate 2. It is characterized in that it can be stored and equipped, and a tray 6 is installed below the cover table 5 so that it can be pulled forward in a horizontal state.

The sitting delivery table has foot supports 7.7 for supporting the soles of the pregnant woman's feet in front of both sides of the thigh support 4, hand grips 8.8 on both sides of the front end of the lifting table 1, and furthermore, It is preferable to equip both sides of the back plate 2 with armrests 9.9. Further, the thigh support 4 and the buttock support 3 are integrated, and the buttock support 3
In addition to tilting around the pivot together with the thigh support 4, it is also possible to make both parts separate. If they are separated, when the thigh support 4 tilts upward from the horizontal position, the buttock support 3 moves in conjunction with this, and when the thigh support 4 tilts downward from the horizontal position, the buttock support 3 is maintained at the horizontal position. This is desirable.

(Function) In the seated delivery table with the above configuration, during the stage of labor before delivery and during observation of the progress after delivery, the thigh support 4 is tilted and retracted downward as shown in Fig. 3. The leather stand 5 is pulled out forward so that it is approximately connected to the back plate 2. In this state, the thigh support 4 does not protrude above the side of the armrest 5, so there is nothing that will get in the way of the pregnant woman moving between other bellies or taking a comfortable posture. Then, at the time of delivery, the stepladder 5 is stored in the elevator platform 1, the femoral bone 4 is rotated upward, and the thighs of the pregnant woman are held in an open state. Further, the soles of the pregnant woman's feet are supported by the footrests 7.7, the back plate 2 is erected at an appropriate angle, and the tray 6 is pulled out below the buttocks 3, so that preparations for delivery are made. Therefore, the pregnant woman assumes a sitting posture leaning against the buttocks 3 and the back plate 2, and holds the hand grip 8.8.
You will have to push while grasping the baby and give birth.

(Example) Next, an example will be described. In the figure, the elevating table 1 includes a base portion 11, an elevating mechanism 12 mounted on the base portion 11, and an elevating table frame 13 mounted on the elevating mechanism 12. The elevating mechanism 12 employs a combination of hydraulic means and a parallel link mechanism or other known means, and its periphery is concealed by a bellows 14. A pivot shaft 10 is horizontally mounted on the front end of the upper surface of the lifting platform frame 13, and on the pivot shaft 10, a back plate 2, a femoral bone 4 integrated with a buttocks portion 3 are attached.
and support rods 70.70 for the footrests 7.7 are pivotally mounted so that they can each rotate in a vertical plane about the pivot shaft 10.

The stepladder 5 includes a frame 50 whose front end is pivotally connected to the pivot 10.
It is equipped so that it can be slid back and forth inside. The frame body 50 is capable of vertically swinging around the pivot shaft 10, and is elastically biased in the counterclockwise rotation direction in the drawing by a spring 51 stretched between it and the elevator frame 13, and the stopper 52 is raised and lowered. It is maintained in a horizontal state by elastic contact with the stand frame 13. The stepladder 5 is moved back and forth and forwarded by a motor 53 installed in the frame 50, and the power of the motor 53 is transmitted through a straight guide rod fixed along the longitudinal direction on the bottom surface of the stepladder 5. Figure 10 shows the feeding/feeding mechanism of the stepladder 5. In the figure, a plurality of rollers 54 are provided on both inner surfaces of the frame 5o along the longitudinal direction. A movable rail 55° 55 is sandwiched between the upper and lower rollers 54 so as to be slidable back and forth. On the opposing inner surface of the movable rail 55, 55, a plurality of rollers 55a are provided along the longitudinal direction.
The rollers 55a, .
It is stored inside the building so that it can be transferred. As a result, the stepladder 5
is supported by a movable rail 55.55 through rollers 55a, and is slidable relative to the movable rail 55.55 along its longitudinal direction. Therefore, the motor 5
3, the back and forth movement of the stepladder 5 is caused by the relative sliding of the movable rail 55.55 with respect to the frame 50 and the relative sliding of the movable rail 55.5.
This is done by a compound movement of relative sliding of the stepladder 5 with respect to the stepladder 5, thereby making it possible to ensure a large forward and backward feeding and feeding stroke of the stepladder 5. It goes without saying that stoppers are formed between the frame 50 and the movable rail 55.55 and between the movable rail 55.55 and the stepladder 5 to prevent them from being pulled out from each other.

A tray support member 61 is housed in the elevator platform frame 13 in a horizontal manner and can be pulled out in front.
When the tray 6 supported by the tray 6 is pulled forward, it is positioned directly below the puncture part 31 of the buttocks 3. The support member 61 is a rectangular frame made of steel or the like, and the tray 6 is replaceably installed within this frame. Sliding members 62, 62 are attached to the outer surfaces of both left and right sides of the support member 61 along the longitudinal direction, and the sliding members 62, 62 are guide members formed on the inner surfaces of both sides of the lifting table frame 13. 63.63 (see FIG. 5), and the support member 61 can be pulled forward by relative sliding of the sliding member 62.62 with respect to the guide member 63.63. The relative height of the tray 6 to the buttock area 3 is set to match the length of the umbilical cord of the fetus to be removed. Note that the mechanism for pulling out and storing the support member 61 is not limited to the one shown in the drawings, and may be implemented using rollers or the like. Further, in the illustrated example, the drawing and storing are performed manually, but it is of course possible to perform this using an electric motor or the like.

The back plate 2 is pivoted to the pivot shaft 10 through the back plate frames 21.21 on both sides, and has a drive means (air or oil cylinder) 20 installed in the lifting platform frame 13 and a back plate frame 21.21. Links 22.2 connected between
3, it can be tilted up and down around the pivot 10. The back plate 2 is approximately -10° to + with respect to the horizontal position.
It can be tilted within a range of 55 degrees and can be stationary at an appropriate angle depending on the treatment mode. In particular, in this embodiment, a negative side, that is, a backward tilted position is possible, and consideration has been made so that pregnant women with anemia can be treated by having them lie down with their heads lowered. In this case, when the back plate 2 is tilted to the negative side, it hits the frame 50 of the hood 5 as shown in FIG. Therefore, the spring 5]
If the back plate 2 and the frame body 50 are further tilted and pressed against the elastic force, the frame body 50 will also be tilted backward. In other words, with such a mechanism, the cover plate 5 is installed so as to be able to be stored directly below the back plate 2, but the cover plate 5 does not pose any obstacle to the rearward tilting of the back plate 2.

Incidentally, the upper surface of the lifting table frame 13 is inclined backwardly so as to allow the back plate 2 and the cover plate 5 to tilt backward.

Armrests 9 are provided on both sides (or one side is fine) of the back plate 2.
9 has been crusted. A fan-shaped bracket 90 is fixed to the lower surface of the armrest 9, and the bracket 90 is pivotally attached to the side of the back plate frame 21 via a shaft 92.
It is said to be able to rotate freely around 2. A circular arc groove 93 having a center of curvature around the shaft 92 is formed in the bracket 90, and an operation knob 91 inserted through the circular groove 93 is screwed onto the side of the back plate frame 21. The operation knob 91
．． The edge line 91 allows adjustment of the vertical angle of the armrest 9.9. This armrest 9.9 is
It functions so that pregnant women can take a more comfortable position by placing their arms on it before and after childbirth, and it is also preferably used during intravenous injections.

In the embodiment of FIGS. 1 to 12, the buttock support 3 and the thigh support 4 are integrated, and their common two-sided frames 34, 34
It is pivotally connected to the pivot 10.

The buttock support 3 and the thigh support 4 are connected to the lifting platform frame 13.
It is rotatable around a pivot 10 by a drive means (air or oil cylinder) 40 installed inside, and the range of rotation is at least +20° with respect to the horizontal position to send out and send in the cover plate 5. It is set to ensure a range of forward tilt angle that does not get in the way.

The buttock support 3 has a cut-out part 31 formed in the front center thereof,
Thigh supports 4.4 are formed on both sides of the cutout 31. An outwardly curved thigh restraint part 41.41 is formed at the front end of the thigh support 4.4 and projects upward, and the buttock support 3
The legs of a pregnant woman seated on the chair are held open from the inside. Although not shown in the figure, the thigh support 4
．． It is of course possible to make it possible to adjust the leg opening angle, etc. of No. 4, and to make it possible to take appropriate measures according to the individual differences of pregnant women or medical conditions.

On the outside of the thigh support 4.4, support rods 70.70 for the foot support, which are pivotally connected to the pivot 10, are arranged in parallel, and the support rods 7o, 70
A footrest 7.7 for supporting the soles of the pregnant woman's feet is fixed at the front end of the footrest. The support rod 70 is a base rod 71 pivotally connected to the pivot 1o.
, an intermediate adjustment rod 73 connected to the base rod 7 with a handle 72 so that the width and vertical angle can be adjusted; and a front support connected to the adjustment rod 73 with a knob 74 so that the horizontal angle can be adjusted. The footrest 7 is attached to the front end of the front support rod 75 using a knob 76 so that its horizontal angle can be adjusted. Therefore, by operating the handle 72 and knobs 74 and 76, the operator or assistant can adjust the width or angle of the support rod 7o depending on the individual differences in the legs of a pregnant woman.

The support rod 70.70 of the footrest 7.7 is rotatable around the pivot 10, and this rotation mechanism will be explained. In FIGS. 2, 11, and 12, an arc-shaped guide groove 77.77 having the axis of the pivot 10 as the center of curvature is formed on the inner surface of the base rod 71.71.
7.77, pins 34a, 34a protruding from both sides of the common frame 34.34 of the buttock support 3 and the thigh support 4 are inserted so as to be slidable along the axial direction of the groove. The guide grooves 77 and 77 have a cross section shaped like C-shaped steel, and the pins 34a and 34a having small diameter parts are inserted so as to mesh with each other as shown in the figure, thereby absorbing the straining force of the support rods 7o and 70 to the left and right. be done. Stop members 77a, 77a are fixedly installed at the upper ends of the guide grooves 77, 77, and the corresponding stop members 77a, 77a
The support rod 7
o, 70 are supported and rotate around the pivot 10 in conjunction with the buttock support 3 and thigh support 4. In this way, by rotating the support rods 7o and 7° around the axis 10 in conjunction with the buttock support 3 and the thigh support 4, the legs of the pregnant woman can also be adjusted when the pregnant woman is seated at an appropriate angle for childbirth. It will be placed in an appropriate position and will not cause discomfort to the pregnant woman. On the other hand, stoppers 15.15 are protruded from both sides of the lifting platform frame 13, and when the base ends of the base rods 71.71 hit the stoppers 15.15, the support rods 7o, 7o will no longer rotate. This is done in a way that prevents people from doing so.

That is, when the buttock support 3 and the thigh support 4 rotate upward, they rotate together due to the support of the pins 3.4a and 34a against the stop members 77a and 77a, and when they rotate downward, they rotate together. Although it rotates cooperatively due to its own weight, the base rod is 71.71
When the base end of the rod hits the stopper 15.15, the support rod 70.7
0 remains at that position, and then the pins 34a, 34a slide in the guide grooves 77, 77, and the buttock support 3 and the thigh support 4
continues to rotate and is retracted to a position where it does not interfere with the feeding/feeding of the cover plate 5. The reason why such a differential mechanism is provided between the buttock support 3, the thigh support 4, and the foot support 7.7 is as follows.
During childbirth treatment, it is desirable that the two be interlocked as described above, but if the buttock support 3 and the thigh support 4 are interlocked until they are retracted, depending on the height of the lifting table 1, the foot support 7.7 This is because it may hit the floor and become unable to rotate further downward. In addition, this allows the bottom dead center of the platform 1 to be made as low as possible, which is advantageous for pregnant women to get on and off the platform. Therefore, the stopper 15.
15, a stop support (not shown) is provided on the lower surface of the foot support 7.7, and after this support hits the floor, only the buttock support 3 and thigh support 4 can continue to rotate. It is also possible to do as follows. In the case of the illustrated example, lb- stops before the foot rest 6.6 hits the floor surface, so there is no fear that the operator will jam his or her toes when standing in front of the buttock rest 3 for treatment.

The base end of the base rod 71.71 has a hand grip 8.8.
is fixedly installed so that a pregnant woman seated on the buttock support 3 can grasp it. In addition, the driving means 20.40
is disposed in the space between the cover plate 5 and the tray 6 to make it more compact.

In this manner, the pregnant woman is seated on the buttock support 3 and her legs are held apart by the thigh support 4.4, and the back plate 2 is tilted and stopped at an angle appropriate for childbirth, and the buttocks support 3 and large Thigh support 4
．． 4 to an angle commensurate with this (at this time, the footrests 7.7 also move at the same time), and further pull out the tray 6 forward, the preparation for delivery is ready.

Before and after delivery, the back plate 2 is tilted backward, the buttock support 3 and the thigh support 4.4 are rotated downward, and the buttock support 3 and the pivot shaft 1 are rotated downward.
0 from the gap between the legs of the pregnant woman. It can be placed on the stand 5 and placed in a comfortable state.

When a pregnant woman has anemia, appropriate measures can be taken by tilting the back plate 2 further toward the negative side to lower the pregnant woman's head after delivery.

FIG. 13 shows the buttock support 3 and thigh support 4.4 as separate bodies. Both are separately pivoted to a pivot 10 and can be rotated around the axis, but the horizontal position [13th
In the upper range from [see figure (a)], both rotate together [
See Fig. 13 (c)], and only the thigh support 4.4 rotates in the range below the horizontal position [see Fig. 13 (b)]
. That is, the thigh support 4.4 can be rotated around the pivot shaft 10 by the same driving means 4o as described above, and the buttock support 3.
is supported so as to ride on the base frame 42 of this thigh support 4.4. After the frame 32 of the buttock support 3 comes into contact with a stopper 16 fixed to the elevator frame 13, downward rotation is prevented and the frame 32 is maintained in a horizontal state. Therefore, when actuating the drive means 4o to rotate the thigh support 4.4 upward from the horizontal position, the hip support 3 is rotated while supporting it, and when it is rotated downward, the hip bone 3 is under its own weight. The frame 32 rotates together with the femoral bone 4.4, and after the frame 32 hits the stopper 16, the hip bone 3 is maintained in a horizontal state, and only the femoral bone 4.4 rotates and the stepladder 5 is rotated. It is evacuated to a position where it does not interfere with delivery and delivery. In this case, the stepladder 5 is advanced and retracted so as to be in contact with the lower surface of the hip bone 3, and in the extended state, the stepladder 5 is continuous with the back plate 2, including the hip bone 3. , its function is no different from the above.

Figures 14 and 15 show the mechanism shown in Figure 13 and the mechanism shown in Figure 11.
This is a combination of the mechanisms shown in Figures 1 and 12. In FIG. 14(a), the hip bone 3 and the femoral bone 4 are in an overlapping state, and when the cylinder that is the driving means 40 is extended in this state, the hip bone 3, the femoral bone 4, and the foot rest 7 Basics 7
1 cooperates and rotates upward around the pivot 10.

Further, when the driving means 40 is retracted from the state shown in FIG. 14(a), the hip bone 3 and the base rod 71 are stopped by the stoppers 16 and 15 and come to rest, as shown in FIG. 14(b), and the thigh Only bone 4 rotates downward. In this state, the stepladder 5 can be sent forward.

(Effects of the Invention) As described above, in the seated delivery table of the present invention, the stepladder for placing the legs above the elevating table is equipped to be stored so as to be able to be sent forward from directly below the back plate, and is also large. Since the thigh bone can be retracted to a position where it does not get in the way when the stepladder is being moved in and out, it is possible to immediately put the pregnant woman in a comfortable position before and after childbirth, and it is also possible to move to another bed. Transfer can also be done easily without the femoral bone getting in the way. In addition, the fetus receiver 1-ray is stored in the front so that it can be pulled out, so it can be pulled out only when necessary, such as during delivery, and stored when it is not needed. It never becomes. Furthermore, the entire device becomes compact, there is no need to separately secure a storage area for an auxiliary bed, the removed femoral bone, etc., and the delivery room can be properly organized. The practical value of the present invention having such remarkable effects is extremely large.
