Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sitting delivery table that is comfortable for pregnant women and midwives (doctors, nurses).

Sitting childbirth has recently been reconsidered for pregnant women because of the concentration of childbirth force due to this position, and for midwives because it allows midwives to perform midwifery work in a position closer to the pregnant woman's delivery site compared to supine delivery. be.

Japanese Patent Application Laid-Open No. 54-131393 as a conventional sitting delivery table
(with A), JP-A-57-150960 (with B), Jitsukai Sho
58-105322 (C), and JP-A-58-81032 (D
However, in A, the angles of the pregnant woman's spine and thighs are tilted in an immovable fixed relationship, so there are individual differences between pregnant women, such as being prone to anemia or having a breech baby. The disadvantage is that it is not possible to adjust the angle of the back plate and thighs to accommodate the birth canal, but although B has a back plate and supporting legs, there is no support for the thighs, so it is difficult to create a sufficient birth canal. The same goes for point C, which is difficult to secure. Although D discloses the idea of detaching the buttock support and connecting the stretcher, in this case the seat plate cannot be tilted, so the buckled posture can only be adjusted by the back plate during childbirth. It is difficult to tilt the buttocks to adopt an appropriate posture using the seat plate on which the buttocks are seated, and although there is a thigh support part, there is no supporting leg part, so the problem remains that the legs are easily fatigued.

Therefore, an object of the present invention is to provide a delivery table that can also tilt the seat plate, thereby making it possible to adjust the angle of the buttocks according to the individual differences of pregnant women. Another object of the present invention is to connect a stretcher along the body axis of the delivery bed to facilitate the transfer of a pregnant woman, and, if the stretcher is removed, the midwife can perform midwifery operations in a more comfortable position than in the midline direction of the pregnant woman. The aim is to provide what can be implemented. Still another object of the present invention is to provide a delivery table in which the thigh support is removable from the seat plate, so that it does not interfere with the pregnant woman and the midwife on the stretcher when the stretcher is connected.

Other objects and advantages of the invention will become more apparent from the following description, which illustrates a preferred embodiment.

Fig. 1 is a plan view showing an embodiment of the seated delivery table of the present invention, with no stretcher attached, Fig. 2 is a plan view of the embodiment with a stretcher attached, and Fig. 3 is a plan view of the same embodiment with a stretcher attached. FIG. 4 is a side view corresponding to FIG. 1, and FIG. 4 is a side view corresponding to FIG. In the figure, 1 is a base that is raised and lowered by a lifting mechanism 2 (oil cylinder mechanism, motor mechanism, etc.), and inside this base 1 is a seat plate 3 and a back plate 4 for tilting independently or in conjunction The oil cylinder mechanisms (motor mechanisms...not shown) are arranged in the same horizontal plane area while maintaining a parallel relationship with each other. The details are omitted here as they are currently under separate application. Seat board 3
Since the back plate 4 is placed on the base 1 in a tiltable state, it can be raised and lowered to any desired height by the lifting mechanism 2. Reference numeral 5 designates a thigh support portion stacked on the seat plate 3 as shown in FIG.
The front surface thereof is provided with a hollowed out part 51 and thigh receiving parts 53, 53 which stand diagonally upward on both sides thereof and are coupled with restraining pieces 52, 52 at positions corresponding to the inner side of the thighs. As shown in FIG. 1, the seat plate 3 is shown as having a substantially square-shaped plane with a chevron-shaped cutout 31 on the front surface. Reference numeral 7 denotes a bracket that projects diagonally forward from both sides of the seat plate 3. At the tip of this bracket 7, a support leg 8 for supporting the legs of a pregnant woman is attached via an adjustment member 9. The adjustment member 9 allows the support leg 8 to be adjusted in three directions: height, horizontal rotation, and forward/backward tilting, but since this mechanism is also being filed in a separate application, a detailed explanation will be omitted. Reference numeral 10 is a grip projecting rearward from the middle of the bracket 7, which helps the pregnant woman to brace herself during childbirth. Reference numeral 11 is an angle indicator fixed in the middle of the bracket 7 toward the front, that is, toward the midwife, and displays the tilt angle of the seat plate 3 and the back plate 4 to help adjust the angle appropriately. Reference numeral 12 denotes an arm rest for intravenous injection (for intravenous injection) which is disposed on both sides of the back plate 4 via angle adjustment members (not shown), and the angle can be adjusted regardless of the angle of the back plate 4. Adjustment allows it to be held almost horizontally. A tray storage bin (not shown) is provided directly below the seat plate 3, and a tray (not shown) for receiving a newborn baby can be inserted into the storage bin from the front toward the rear. Base plate 13 of stretcher 13 with casters
A pair of downward pins 14 are protruded from the rear end of the seat plate 3 so that the pins 14 can be fitted into the pin holes 32, 32' of the seat plate 3 which fit into the stop pins 6, 6. It's getting old. Immediately below this base plate 131, a chevron-shaped connecting plate 132 is stacked downward, which fits into the chevron-shaped cutout 31 of the seat plate 3 from the body axis direction and is connected to the seat plate 3 without wobbling. .

The procedure for using the device of the present invention will be described. First, in a state where the stretcher 13 and the delivery table 15 are separated as shown in FIG. 1, by lifting the thigh receiver 5 including the thigh receivers 53, 53 upward as shown in FIG. Insert the stop pins 6, 6 into the pin holes 3 of the seat plate 3.
2, 32, detach from the seat plate 3, and remove the base plate 1.
The lifting mechanism 2 is operated to lower the seat plate 3 and the back plate 4 so that they are slightly lower than 31. Next, the pregnant woman P is placed on the stretcher 13 in a supine state, and the seat plate 3 is approached along the body axis direction from the front of the seat plate 3.
31 of the chevron-shaped connecting plates 132 are brought into contact with and aligned slightly above the chevron-shaped hollowed out portions 31 of the seat plate 3. Subsequently, when the lifting mechanism 2 is operated to raise the seat plate 3 a little, the pin holes 32, 32 fit into the downward pins 14, 14 of the chevron-shaped connecting plate 132 from below, and the chevron-shaped connecting plate 1
32 and the chevron-shaped cutout 31 of the seat plate 3 are tightly fitted together without any play (see FIGS. 4 and 2). From this state, the pregnant woman P was moved to the back board 4 by herself and with assistance.
Transfer to the seat plate 3 side. In this case stretcher 1
Although the rear caster 3 is slightly raised above the floor, the stretcher 13 and the delivery table 15 are firmly connected by the above-mentioned tight fit, so the stretcher 13 can maintain stability. When the transfer of the pregnant woman P is completed, the delivery table 15 is lowered a little to release the engagement between the pins 14, 14 and the pin holes 32, 32, the stretcher 13 is separated from the delivery table 15, and the thigh support part 5 is attached to the seat plate. Place it on the seat plate 3 from above 3 and insert the downward pins 6, 6.
are fitted into the pin holes 32, 32 of the seat plate 3, respectively, to fix the thigh support plate 5 to the seat plate 3. In preparation for childbirth, pregnant woman P's back is placed on the back plate 4, and her buttocks are placed on the seat plate 3.
Both thighs are placed or ridden on the thigh supports 53, 53, and the feet are placed on or mounted on the support bases 8, 8, respectively, and both hands are gripped by the legs 10, 10 (see FIG. 3). When delivery approaches, the back plate 4 and the seat plate 3 are tilted in the required direction and angle by a tilting mechanism (not shown) either in conjunction or independently. Thigh receiving part 53,
53 works in conjunction with the seat plate 3 to always maintain a constant angle with respect to the seat plate 3, so the angle between the buttocks and thighs is always maintained at the same level, so that no unnatural feeling or pain occurs. The support legs 8, 8 can be raised and lowered, horizontally rotated, and tilted back and forth independently of the seat plate 3 by the adjustment device 9, so that the uncomfortable feeling of support caused by the difference in leg length can be avoided by this adjustment. It can be resolved. In general, it is said that the best conditions for a seated birth are for the back plate 4 to be at an angle of approximately 30 degrees, and for the seat plate 3 to be approximately perpendicular to the back plate 4. Monitoring can be easily done by visually checking the angle indicators 11, 11.
The midwife sits on the seat plate 3 after separating the stretcher 13.
They can engage in the extraordinary tasks necessary for midwifery while standing in the front midline direction without being forced into an unreasonable position. When intravenous injection is required for pregnant woman P, the intravenous injection arm rests 12, 12 can be always kept horizontally, regardless of the inclination angle of the back plate 4, by means of an adjustment mechanism not shown. When a pregnant woman with anemia or a breech delivery begins, the back plate 4 should be set to the minor side (the side tilted diagonally below the horizontal) and the seat plate 3 should be tilted accordingly. This makes it possible to respond to various types of childbirth emergencies. By storing the tray in a tray storage bin (not shown) provided under the seat plate 3, the newborn baby and her accompanying items are accommodated in the tray. In the present invention, which uses the grips 10 and 10 to assist in holding the tension during childbirth, it is easier to concentrate the force on the birth canal compared to the conventional method of holding the horizontal bar overhead with both hands. Natural and more effective. When childbirth is finished, the seat plate 3 and the back plate 4 are returned to almost horizontal positions at the appropriate time, and the thigh supports 53, 53,
Both thighs and both legs are removed from the supporting legs 8, 8, and the pregnant woman P is placed horizontally on her back on the delivery table 15 and left undisturbed for the necessary time, after which the stretcher 13 is delivered again in the manner shown in Fig. 4. The work is completed by connecting to the stand 15 and transferring the pregnant woman P to the stretcher 13 side. The thigh receivers 53, 53 have a restraining piece 5 only on the inside as shown in the figure.
2, 52 and the outer side is open, so it is more liberating than the type that wraps the entire thigh.

In addition, in the example diagram, the stretcher 13 and delivery table 1
5 has been shown as being integrally connected via the seat plate 3, but is not limited to this, for example, the stretcher 1
3 to the base 1 at the bottom of the seat plate 3, other connection means may be adopted. back plate 4, seat plate 3,
The best mode for the tilting and adjustment mechanism of the support leg portion 8 is the one currently under application, but it is needless to say that it is not limited thereto. Thigh receiving part 53,
53, connect the thigh receiver 5 with the downward pins 6, 6.
Alternatively, it is also possible to attach and detach only the thigh receivers 53, 53 to and from the seat plate 3 using the pins 6, 6 and the pin holes 3.
It can be adopted along with 2.32 other alternatives.

As is clear from the above explanation, the present invention allows not only the back plate but also the seat plate to be tilted, so that the buttocks can be tilted appropriately with respect to the back depending on the individual differences of pregnant women, and the posture suitable for childbirth or emergency situations can be adjusted. The stretcher for pregnant women can be easily transferred between the seats because the thigh support can be detached from the seat plate and the stretcher can be connected to the front side of the seat plate. With the stretcher separated, the midwife can position herself in the direction of the body axis of the delivery table and engage in midwifery work from the midline, making it possible to perform accurate treatment in a comfortable position. It has an excellent effect that eliminates the problems associated with delivery tables.
