Description

[Detailed Description of the Invention] The present invention relates to a birthing table, and during childbirth, it is possible to apply sufficient force to the birth canal by curling the body in a supine state in a shape that follows the birth canal and pulling the legs sufficiently toward the abdomen. It has long been known that this is the ideal mode of delivery.

However, since conventional childbirth is performed on a flat bed, the woman may end up in an arched position, which is the opposite of the above.
Even when curling up, the woman must ask the help of a midwife to do so on a flat bed, and her legs are bent by a footrest even before she enters a complete delivery state, so they are in a strong open position. It was becoming more and more tiring.

The conventional delivery table disclosed in Japanese Utility Model Publication No. 39-35075 includes a fixed floor plate that is fixed to the delivery table frame and on which the lower back of the pregnant woman comes into contact, and a fixed floor plate that is connected to the fixed floor plate via a connecting shaft, and which is connected to the fixed floor plate through a connecting shaft, and which is connected to the delivery table frame and on which the lower back of the pregnant woman comes into contact. A bed is formed by the bedside floorboard that comes in contact with the bedside bedboard, and the bedside bedboard is raised and lowered by manual rotation of an operating bundle provided at the end of the frame metal, and a link mechanism consisting of a gripping rod, a horizontal series of strokes, and a footrest support plate is activated. It is installed on both sides of the delivery table, and the foot plate is raised by the pregnant woman pulling the gripping rod.

In this delivery table, the floorboard that the pregnant woman's lower back comes into contact with is simply fixed horizontally to the delivery table frame. When being towed, the midwife's lower back slides along the fixed floorboard toward the foot of the delivery table.

In other words, because the structure of the bed itself does not have a means to prevent the movement of the pregnant woman's lower back, the more the pregnant woman grips the gripping rod and presses her feet on the foot plate, the more her body shifts. It is extremely unstable.

In addition, it is generally expected that the pushing force of the legs is more than three times the pulling force of the grasping rods by the arms, so in the above-mentioned delivery table that uses human power, when the lever ratio of the link mechanism is 1, Power cannot withstand pressure.

Therefore, when the lever ratio is changed so that the arm can be pulled with the force of the arm, the amount of movement of the foot receiving plate decreases, making it impossible to ensure a practically sufficient lifting stroke.

Furthermore, in this conventional delivery bed, when the bedside bed board is raised diagonally and the pregnant woman pulls the grasping rod for exercise, the midwife's lower back slides toward the foot of the delivery bed along the fixed bed board. Therefore, no matter how much the foot plate is lifted by pulling the grasping rod, there will be no significant pressure effect on the abdomen of the pregnant woman.

The present invention eliminates these drawbacks, accurately holds the pregnant woman's body in the most suitable position for childbirth, compresses the abdomen of the pregnant woman by tightening the abdominal girdle, assists in the expulsion of the fetus, and at the same time helps expel the fetus during the intermittent stages of labor. This allows a pregnant woman to put her body into a natural sleeping state.

Furthermore, this state can be brought about in conjunction with the natural straining state of the pregnant woman during labor pains.

One embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a bed formed by bendably connecting a plurality of forming members 4, 5, 6 by connecting shafts 2, 3, and is placed on a base γ. It is location.

Reference numeral 8 denotes an operating lever located on both sides of this bed 1 so that the pregnant woman 9 can easily grasp it, and the lower end is fixed to a part of the base γ with a shaft 11.
Two holding parts 12 and 13 are formed at appropriate intervals at the upper end so that one of them can be held according to the height of the pregnant woman 9.

Reference numeral 14 denotes a cylinder that is activated by closing an IJ switch or the like when the operating rod 8 is pulled, and a piston rod 15 is actuated by an appropriate method such as hydraulic pressure, pneumatic pressure, or an electric motor. is fixed to the lower surface of the bed 1 via a fixed shaft 16.

The connection to the bed 1 is a forming member 6 on which the waist of the pregnant woman 9 is placed among the plural forming members 4, 5, and 6, and is fixed in the direction of the adjacent forming member 5.

A guide rail 11 is fixed to the back surface of the forming member 4 located toward the head of the pregnant woman 9, and is slidably in contact with the lower surface of a roller 18 fixed to the base 7.

Reference numeral 20 denotes an abdominal belt that is placed around the abdomen of the pregnant woman 9. Connecting metal fittings 21 fixed to both ends of the abdominal band 20 are fixed to the upper end of a cam 22, and one end of this cam 22 is attached to one side of the forming member 6 so as to be rotatable by a fixed shaft 23. The upper limit of the rise of the connecting fitting 21 is regulated by fixing it to the connecting fitting 21 and abutting the other end against the protrusion 24 on the side surface of the forming member 6.

Reference numeral 25 denotes a pressing roller protruding inward from the operating rod 8. When the cam 22 descends together with the bed 1 as the bed 1 is bent downward by the operation of the cylinder 14, it comes into contact with the lower end of the inclined surface 26 of the cam 22. By moving the cam 22 on the inclined surface 26 by strong pulling of the operating rod 8, the cam 22 is rotated about the fixed shaft 23 as a fulcrum, as shown by the two-dot chain line in FIG. do.

Reference numerals 27 and 28 denote support rods for the footrest 29, which consist of two sets located in parallel at appropriate intervals, and are formed on both sides of the bed 1. The base end of the support rod 27 of one of the two sets is is rotatably fixed to a fixed protrusion 32 protruding and fixed on the base T with a fixed shaft 33, and the fixed shaft 34 at the base end of the other support rod 28 is connected to one of the support rods 27 with an appropriate interval between the two. It is rotatably inserted into the insertion tube 36 fixed to the fixed protrusion 35 of the table 7, and the fixed plate 37 is fixed to the fixed shaft 34 at the insertion end, and the fixed shaft 34 is fixed on the side of the bed 1 of the fixed plate 37. A pressing protrusion 38 is protruded and fixed at a position offset from the center, and this pressing protrusion 3
8 is in contact with the lower surface of the forming member 6.

40.41 is a fixing screw 4 toward the other end of the support rod 27.2B.
2 and 43, and a fixing rod 44 is fixedly protruded to the side, and the other end of the fixing rod 44 has a fixing rod slidably fixed by fixing screws 45 and 46. 47 is fixed, and on the upper surface of this fixed rod 47, a leg receiving part 48 having a semicircular end face is fixed to supporting parts 53 and 54 which are slidably fixed with fixing screws 49 and 50, and also fixed. An abutting receiver 56 against which the legs 55 of the pregnant woman 9 are abutted is slidably fixed to the outer end of the receiving rod 47 with a fixing screw 51.

In order to position the pregnant woman 9 on the bed 1 in the structure as described above, the bed 1 is laid flat as shown in FIG. The legs 55 are each placed in a spread state, and the abdominal band 20 is placed on the abdomen of the pregnant woman 9.
, and the connecting fittings 21 at both ends are engaged and fixed to the cam 22.

In this state, the abdominal band 20 does not put any pressure on the abdomen of the pregnant woman 9, but is simply placed on the abdomen, and although her legs are in an open position, she is in a stretched position and maintains a comfortable posture. can do.

In this extended state, the hand of the pregnant woman 9 is lightly grasping the holding portion 12 or 13 of the operating rod 8.

Next, when the labor pains come to the pregnant woman 9, she presses the operating lever 8 to endure the contractions.
If you firmly grasp the lever and pull it toward your shoulder, the movement of the operating rod 8 will be detected by a limit switch or other appropriate sensor, and an electric circuit will be connected to operate the cylinder 14 and pull the bed 1 downward with the piston rod 15. Ru.

As the bed 1 is lowered, the forming member 4 of the bed 1,
5.6 is bent from the connecting shaft 2 and 3 parts, and bed 1 is bent from the second
As shown in the figure, it is curved in an arc shape as a whole.

This bending of the bed 1 is performed by the forming member 4 in the direction of the head of the pregnant woman 9.
The guide rail 17 fixed to the back surface of the pregnant woman comes into contact with the rollers 18 and slides to stand up, and the member 5 forming the back part of the pregnant woman 9 moves on the sliding rollers 58 fixed to the base 7. The forming member 6 in the direction 9 is inclined so that the outer end in the fixed direction is upward.

The pressing roller 25, which was in contact with the end surface 59 of the cam 22 when the operating rod 8 was initially pulled, slides on the inclined surface 26 of the cam 22 as the cam 22 descends together with the forming member 6 due to the curvature of the bed 1. By moving and strongly pressing the abdomen of the pregnant woman 9 with the abdominal band 20 as described above, the expulsion of the fetus accompanying the straining is assisted.

Further, as the central portion of the bed 1 is lowered, the pressing protrusion 38 of the support rod 28 that has come into contact with the lower surface of the forming member 6 is also pressed by the lower surface of the forming member 6.

Since the suppressing protrusion 38 protruding from the fixed plate 37 protrudes to a position offset from the axis of the fixed shaft 34, the fixed shaft 34 is rotated via the fixed plate 37 by being suppressed by the forming member 6, and the supporting rod 27, 28 is raised as shown in FIG. 2, and the legs of the pregnant woman 9 are raised and spread.

Due to this leg-high open state, the body of the pregnant woman 9 is formed into a round shape that conforms to the birth canal, and an effective force for expelling the fetus is applied to the birth canal.

When labor is interrupted, the attractive force on the operating rod 8 is released and the operating rod 8 is lightly pushed back to operate the cylinder 14 in the opposite direction to that described above by connecting an electric circuit such as a limit switch, and the piston rod 15 is protruded. As a result, the bed 1 returns to its original position, and the support rods 27 and 28 can also return to their original positions, allowing the pregnant woman 9 to return to the comfortable supine position shown in FIG.

Moreover, if the operating lever 8 is activated by the next contraction, it becomes possible to take the same posture as described above.

In the above embodiment, the bed 1 is divided into three forming members, but the dividing of the forming members is not limited to three. It is possible to reliably follow the birthing position shown in No. 9.

However, if the forming member is divided into a large number of parts, there is a drawback that the structure becomes plural, so in one embodiment, it is divided into three parts.

When the pregnant woman pulls the operating rod 8, the cylinder 14 is actuated to pull down the central part of the bed 1, thereby forming a bed forming member 5, which the pregnant woman's back comes into contact with, and a bed forming member 6, which her waist touches. The legs are bent into a V-shape when viewed from the side, and the footrest 29 is pushed up to bend the pregnant woman's legs toward the abdomen. Therefore, even if the pregnant woman strongly pulls the operating rod 8, her waist will not slide along the bed forming member 6 towards the foot of the delivery bed.

In other words, the body of a pregnant woman who is bent forward on her back is viewed from the side V.
The bed forming member 6, which fits into the recess between the bed forming members 5 and 6 which are bent into a letter shape and is inclined in the opposite direction to the bed forming members 4 and 5, provides great resistance to the shifting movement of the pregnant woman's body. Since it acts as an element, it is possible to precisely hold a pregnant woman's body in the most suitable posture for childbirth.

Further, when the pregnant woman is pulled, the abdominal band 20 is tightened as the operating lever 8 is moved by the operation and presses the abdomen of the pregnant woman, thereby increasing the intra-abdominal pressure effective for expelling the fetus.

In this way, by ensuring that the optimal position for childbirth is maintained and by applying sufficient pressure to the pregnant woman's abdomen,
Childbirth is assisted and a healthy birth is achieved.

Moreover, this posture is created by the woman's control levers being pulled together during the labor pains, and during the intermittent stages of labor, the woman can be in a comfortable supine position, which does not cause unnecessary fatigue to the woman. The formation of the above-mentioned childbirth posture is done by the mother herself, so it does not cause her to feel anxious.
In addition, it is now possible for pregnant women to adjust their childbirth posture and the degree of compression of the abdomen by the abdominal belt 20 based on their own judgment. It also makes it possible to incorporate judgment, and also relieves the labor of the birth attendant to hold the pregnant woman's body in the childbirth position.

Furthermore, in the delivery table of the present invention, the central part of the bed 1 is pulled down to bend the bed forming members 5 and 6 into a V-shape when viewed from the side, and the footrest 29 is pushed up to accommodate the parturient woman. Since the action of bending the legs toward the abdomen is performed by the fluid pressure of the cylinder 14, it is possible to easily obtain a compression force effective for assisting in childbirth.
The lifting stroke of the footrest 29 can be made as large as necessary, regardless of the physical strength of the pregnant woman who operates the operating rod 8.
