DETAILED DESCRIPTION OF THE INVENTION

[0001]

FIELD OF THE INVENTION The present invention relates to a delivery table which is convenient for both women and physicians, especially for labor and delivery.
Delivery method in a single room throughout the postpartum follow-up period = LDR
A delivery table suitable for sitting.

[0002]

2. Description of the Related Art A supine delivery table widely used in Japan at present consists of a back plate, a hip support, a lower leg support (more precisely, a popliteal support) or a heel support. The leg is kept open by supporting the lower leg support or the heel with the heel support. However, in the supine delivery table, (1) in the second stage of delivery (until the fetus passes through the pelvic cavity and is delivered), the upper body moves and it is difficult to obtain the abdominal pressure required for delivery, and delivery assistance is difficult. (2) In order to secure the habitability in the first stage of delivery (until the cervix is fully opened), the buttocks are widened.
Opening the leg in the pregnancy period places a burden on the woman, (3) the child is likely to have supine hypotension syndrome, (4) the delivery direction of the fetus does not match the gravity, and And (5) the entire delivery table must be lowered for lateral assistance, and the appearance of maternity caregivers may be mentally unfavorable. Was.

The present inventor has proposed a new sitting delivery table for such a supine delivery table (Japanese Patent Laid-Open No. 11-076326).
No.). This sitting position delivery table comprises a back plate, a buttock support, a leg support, and a base provided with these driving means. The leg receiver moves between the lower standby position and the upper use position according to the rotation of the arm extending from the leg receiver driving means, and supports the maternal popliteal fossa by the leg receiver in the use position. It has the feature that it is possible to make a delivery woman a crushing position or a squatting position as a delivery position. Further, a handle to be held by the maternity is provided on the leg support so that the arm can be freely turned in the pulling direction of the maternity from the use position of the leg support so that the leg can be displaced in accordance with the pull of the handle, or the arm can be rotated. The surface is inclined at 70 to 90 degrees outward with respect to the horizontal plane. In any case, it is a device to help sitting calving.

[0004]

In the above-mentioned sitting delivery table,
In order to prevent the obstetrical woman's legs from being closed, a thigh fixing piece is provided on the buttocks support, and the buttocks support is connected to the base in order to connect the stretcher from the back plate to form a continuous surface following the buttocks support. It was detachable. The handling of the buttocks is troublesome, and removing the buttocks for connecting the stretcher means that there is no member to support the buttocks even temporarily, which may give unnecessary anxiety to the mothers and women. . Separately, if the outer shape of the connection surface of the stretcher to the buttocks is a transfer structure of the outer shape of the buttocks, connection can be made so as to form a continuous surface, but in this case, the buttocks are flat, Problems may arise that the birth of a woman cannot be supported during delivery.

Further, the leg receiving portion has a shaft corresponding to the bending of the leg so that the leg receiving portion can be evacuated when it is not necessary. Position), but basically, by inclining the raceway surface of the leg receiving part, so-called bending and stretching of the entire leg by bending and stretching motion, inward and outward rotation and inward and outward rotation of the knee, I was trying to realize rolling and internal and external rotation. It is possible to select the raceway surface that regulates the exercise so as not to impose a burden on the maternity, but it is not necessarily equal to the movement of the hip joint, and a footrest that can exercise more flexibly and without a burden on the maternity is expected. It had been.

In addition, the basic raceway surface of the leg receiving part must pass through the conventional strecher, and even if the attachment and detachment of the buttocks receiving as described above is eliminated, the leg receiving part may be used upward. In order to move to the position, there was a problem that the stretcher had to be temporarily retracted with respect to the delivery table. It is conceivable to move the leg receiving portion from the retracted position to the use position so as to avoid the stretcher, but this requires a complicated structure for supporting the leg receiving portion, which is not always preferable. Therefore, in order to solve each of the above-mentioned problems of the sitting position delivery table which is more preferable for the obstetrics and women, the study was conducted.

[0007]

As a result of the examination, what has been developed comprises a back plate, a buttocks support, a leg support, the above-mentioned respective driving means and a base. In a sitting position delivery table in a use mode of sitting down with the back leaning on, a horizontal rotation is performed so that the thigh of the maternity relative to the hip joint on the buttocks supports the bending and stretching motion, the abduction and inversion and the inward and outward rotation. This is a seating delivery table in which the leg receiving section is driven biaxially by leg receiving section driving means having an axis and a vertical bending axis. That is, the movement of the leg receiving part is decomposed into two axes, the structure is simplified by individually realizing a plurality of movements, and by combining the plurality of movements, the bending and stretching movement of the thigh relative to the buttocks, Realizes inversion and inward rotation and inward and outward rotation. In order to make the pelvic entrance horizontal, the backboard is supported by the backboard drive means arranged on the base and raised by 40 to 45 degrees, so that the maternal who supported the popliteal fossa by the leg receiving part can be crushed or crouched Rank.

Specifically, the leg receiving portion driving means comprises a horizontal rotating portion and a vertical bent portion, and the horizontal rotating shaft is a rotating shaft connecting the leg receiving portion driving base provided below the buttocks receiving portion and the horizontal rotating portion; The vertical bending axis of the leg receiving portion driving means is a rotation axis connecting the horizontal rotating portion and the vertical bending portion, and the rotation of the horizontal rotating portion controls the thigh inward and outward movement relative to the hip joint, and the vertical bending portion The rotation realizes the bending and extension movement of the thigh relative to the hip joint, and the rotation of the horizontal rotation part and the rotation of the vertical bending part work together to realize the rotation of the thigh relative to the hip joint. In this case, the vertical bending axis is inclined with respect to the horizontal plane so that the combination of the bending movement and the inversion / eversion movement can be easily adapted to the movement of the leg, and the track surface of the leg receiving part following the vertical bending part is positioned relative to the hip joint. Should be inclined in the direction of the typical thigh abduction.

It is preferable that a handle to be held by the woman is provided on the leg receiving portion so that the leg receiving portion, which has actually been raised to the use position for supporting the popliteal fossa, can be pulled by the woman's own pull. By gripping the handle provided on the leg receiving part, in the second stage of labor, the maternity woman pulls the handle and pulls her knee to the trunk, temporarily shifting from the crushed position to the crouching position and delivering. To facilitate. When Ikimi subsides and the pull on the handle is loosened, the leg receiving part returns to the use position naturally, and the woman can take the crushed stone position again. From the crushed position to the squatting position, slightly opening the legs is less burdensome for the maternity, so that the orbit of the leg support is slightly open and the track surface of the leg support is outward with respect to the horizontal plane. Incline at 70-90 degrees, preferably around 80 degrees. Further, the leg receiving portion may be provided with a wall surface or a convex portion which comes into contact with the knee from the inside so as to prevent the maternity woman's leg opening along the leg receiving portion from closing.

[0010] In addition, when the back plate is lifted obliquely and the legs are bent at the same time during delivery, it becomes difficult to support the buttocks resting flat, and the body of the maternity becomes unstable. this is,
In the state where the back plate is horizontal, the obstetrics are in the supine position and the buttocks are supported by the rear iliac (above the buttocks) while the body is stable, whereas the lifting of the back plate is above the rear iliac, That is, the back is lifted and the support at the posterior iliac is lost. In the present invention, in order to replace the lost support at the posterior iliac part, the buttocks support consists of a main plane and a pair of left and right sub-planes via a bending axis passing through a position equivalent to the hip joint. A buttocks receiving drive means that is inclined with respect to the body axis and pushes up the sub-plane from below is provided on this sub-plane, and the sub-plane is raised in an inclined state by the bending axis, thereby bending and extending the thigh relative to the hip joint. Exercise, adduction and inward-rotation.

[0011] The support by the sub-plane is at the ischial tuberosity (below the buttocks), and receives the body of the mother who is likely to slip down along the back plate from below, so that the body of the mother is stabilized. At the same time, the bending of the thigh following the sub-plane leads the woman to the crushed position (or squatting position), which also stabilizes the body of the woman as the base of the bent thigh coincides with the buttocks rest. That is, by the movement of the sub-plane, the movement of the thigh in three axes (the horizontal turning axis and the vertical bending axis with respect to the leg receiving portion, and the bending axis with respect to the sub-plane) is better realized. In particular, the turning surface of the inward and outward rotation included in the horizontal rotation axis becomes oblique to the body axis, and the inward and outward rotation (extended rotation) is naturally guided by bending and stretching movement (bending) and inward and outward rotation (abduction) . The angle of inclination of the bending axis with respect to the body axis of the mother is preferably 30 to 45 degrees.

The raising of the sub-plane of the buttocks support is generally desirably linked with the movement of raising the leg support to support the popliteal fossa. More specifically, the leg support and the sub-plane are substantially aligned. It is preferable to form a continuous surface. Therefore, the buttocks receiving drive means is a push-up portion provided on a leg receiving portion driving base serving as a movement base of the leg receiving portion in order to retract the leg receiving portion below the buttocks receiving portion. The push-up portion is pressed from below the sub-plane by raising the leg receiving portion driving base to support the poplitea, and the sub-plane is lifted in an inclined state. The lifting of the sub-plane by the leg receiving portion driving base facilitates realization of the interlocking and substantially continuous surface of the leg receiving portion and the sub-plane as a result.

In addition, a stretcher which forms a plane continuous with the buttocks support is provided detachably with respect to the buttocks support, so that the range of the leg supports in the stretcher can be opened and closed. And, in order to move the leg receiver from the standby position to the use position in a state where the stretcher is connected to the delivery table, a stretcher forming a plane continuous with the buttocks support is provided detachably with respect to the buttocks support, The elevating and lowering passage ranges of the leg receiving portions in the stretcher can be individually opened and closed. For example, it is possible to exemplify a structure in which the stretcher is divided into three parts in the left-right direction, and the left and right surfaces including the up-and-down passage range of the leg receiving part can be retracted with respect to the buttocks receiving part. That is, when moving the leg support from the retracted position to the use position, the leg support appears to pass through the stretcher and rises to the use position while naturally supporting the popliteal fossa. If the sub-plane of the buttocks support is lifted in conjunction with the elevation of the leg support at the stretcher passing stage, a natural transition of the delivery position can be achieved as a result.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a side view showing a sitting delivery table in a state where a stretcher 1 is connected (the first stage of labor-labor, the fourth stage of labor-follow-up, etc.), FIG. 2 is a plan view of the same, and FIG. FIG. 4 is a side view corresponding to FIG. 1, with the buttock removed, FIG. 4 is a plan view corresponding to FIG. 2, in which the buttocks receiving cover 2 is removed, and the stretcher planes 3, 4, 4 are represented by imaginary lines.
Is a side view showing the sitting position delivery table in a state where the leg receiving portion 5 is raised in order to shift to the second stage of delivery, FIG. 6 is the same plan view, and FIG. Or, a side view showing a sitting birthing table in a state of taking a squatting position,
FIG. 8 is a plan view of the same, and FIG.
Front view for explaining lifting (legs are omitted for convenience of explanation)
It is.

As shown in FIGS. 1 and 2, the seating delivery table of the present invention has a buttocks support 7 with a main plane 8 and a sub-plane 6,
6 and the back plate 9 is further tilted horizontally, and the stretcher 1 is placed against the buttocks support 7 so as to form a continuous plane.
Connect and lay the maternity like a one-piece bed.
The base 10 has a built-in waste receiver 11, which is pulled out from the base 10 at the time of the second stage of delivery and suturing or the like, and used as appropriate. The main plane 8 of the buttocks support 7 is recessed with respect to the sub-planes 6, 6 so that delivery and the use of the waste receiver are easy, and the central plane 3 of the stretcher 1 connected to the buttocks support 7 is projected. I have. The stretcher 1 has a built-in footrest 12 extending the plane.

In a state where the stretcher 1 is connected to the buttocks support 7, as shown in FIGS. 3 and 4, the leg support drive base 13 swinging up and down with respect to the base 10 is lowered. Since the flat horizontal turning portion 14 provided on the receiving portion driving base 13 and the vertical bending portion 15 having a built-in vertical bending axis provided on the horizontal turning portion 14 are located below, the leg receiving portion 5 becomes the stretcher 1 Evacuated downward (evacuation position). The horizontal rotating portion 14 and the vertical bending portion 15 constitute a leg receiving portion driving means, the horizontal rotating portion 14 is a horizontal rotating shaft 16 driven by a motor with respect to the leg receiving portion driving base 13, and the vertical bending portion 15 is horizontal. It is connected to the rotating unit 14 via a vertical rotating shaft (built-in vertical bending unit 15) driven by a motor. The leg receiving portion 5 is attached to an arm 17 extending from the vertical bent portion 15, so that the leg receiving portion 5 just reaches the popliteal fossa of the maternity when raised.

In a state where the obstetrical woman is lying (stretching extension position) from the stretcher 1 to the buttocks support 7 and the back plate 9, the obstetrical woman is stretching the legs in a straight line, that is, the legs are in the state of extension, adduction and internal rotation. is there. From this state, the popliteal canal is easily inserted into the leg receiving part 5.
In order to support it, it is necessary to raise the leg receiving portion 5 so as to pass through the stretcher 1 (see FIG. 4). Therefore, in the present invention, as shown in FIGS. 5 and 6, the stretcher 1 moves the left and right side planes 4, 4 parallel to the center plane 3, and moves up and down the leg passages 5, 5. It can be opened and closed. As a result, when the leg receiving portion driving base 13 is raised, the leg receiving portion 5 is naturally supported from the poplitea of the woman to the inside of the knee, and the inner wall surface 23 is brought into contact with the inside of the knee. When the leg receiving portion driving base 13 is further raised, the leg support is completely transferred from the stretcher 1 to the leg receiving portion 5, and the stretcher 1 can be removed from the sitting delivery table.

On the upper surface of the leg receiving portion driving base 13, push-up portions 18, 18 are provided for pushing up the sub-planes 6, 6 of the buttocks receiving portion 7 from below. A roller 22 for reducing or eliminating friction with the sub-plane 6 is attached to the upper surface of the push-up portion 18 in this example. At the transition stage of the leg support from the stretcher 1 to the leg support 5, the push-up portion 18 has not yet contacted the sub-plane 6, but as shown in FIG. 7 or FIG. When the leg receiving portion driving base 13 is raised until the angle reaches the sub-plane 6, the sub-planes 6, 6 are raised with respect to the main plane 3 in an inclined state with the bending axis 19 as a boundary. Thereby, the woman is supported so that the thigh is held by the sub-planes 6, 6 (see FIG. 9). The rising of the sub-plane 6 assists the leg in bending, abduction and external rotation.

In actual use, the push-up portion 18 pushes up the sub-plane 6 and the back plate 9 rises according to the back plate driving means 20 to drive the horizontal rotating portion 14 to move the leg support portion around the horizontal rotating shaft 16. Open 5 When the lifting of the sub-plane 6 by the push-up unit 18 is completed, the main plane 8 is also lifted by the leg receiving unit driving base 13 to promote the bending and elongation and abduction of the thigh as a whole buttocks receiving unit 7 and the vertical bending portion 15 When driven, the leg receiving portion 5 is raised with respect to the leg receiving portion driving base 13 about the vertical bending axis, and reaches the use position. In the use position, the leg receiving portion 5 and the sub-plane 6 form a substantially continuous plane to ensure stable support of the entire thigh. The movement of the leg receiving portion 5 realizes the coordination of the bending motion, the inversion / eduction motion of the knee and the inward / outward rotation motion guided by the two motions, and the leg is flexibly bent, abducted, and outwardly rotated without difficulty. In this way, the mother will take the crushed stone position by natural body movement.

A handle 21 is provided on the leg receiving portion 5 of this embodiment, and the mother 21 can grasp the handle 21 and draw the leg receiving portion 5 toward his / her own side. The movement of the leg receiving portion 5 that grasps and pulls the handle 21 is a bending motion mainly about the vertical bending axis, and the trajectory of the inclined leg receiving portion 5 also guides the abduction motion at the same time. At this time, since the leg receiving portion 5 supports the knee from the popliteal region to the inside, and especially suppresses the closing of the leg by abutting the inner wall surface against the inside of the knee, the obstetrical woman is in good condition (the second stage of delivery). Accordingly, the leg receiving portion 5 is attracted, and the transition from the crushed position to the continuous crouching position is possible without difficulty. At the time of this stomach, the woman tries to lower her buttocks relatively to her knees. On the other hand, in the present invention, the buttocks 7
Are bent with respect to the main plane 3 and rise in an inclined state to support the buttocks so as to be wrapped from the left and right, thereby ensuring the support of the buttocks of the maternity woman. This has the effect of removing the anxiety of the mother.

When the delivery is completed and the delivery of the placenta in the third stage of delivery is completed, the back plate 9, the buttocks support 7 and the leg support portion 5 are arranged so that the back plate 9 is horizontal while the maternity woman keeps the crushed stone position. , 5 are united to form the fourth stage of delivery-suture. At this time, in order to prevent blood or dirt flowing from the buttocks from flowing toward the back, the buttocks support 7 (and the leg support drive base 13) is lowered and the leg support 5 is lowered.
Only to secure the crushed stone level. In the final fourth stage of labor-follow-up, the leg receiving parts 5,5
And lower it horizontally from the backboard 9 to the hip support 7. Then, the stretcher 1 is reconnected to the buttocks support 7 with the left and right side planes 4, 4 opened relative to the center plane 3, and the leg support drive base 13 is moved to move the leg support 5 to the retracted position. When the child is lowered, the mother's leg can be naturally transferred from the leg receiving portion 5 to the stretcher 1 without difficulty. After the follow-up, the obstetrical woman puts on the stretcher 1 and carries out.

As described above, the use of the sitting birthing table of the present invention allows the parturition woman to change the posture between the supine position, the crushed position, and the crouching position naturally without difficulty. In particular, when shifting from the supine position to the crushed position or the squatting position, there is an advantage that the poplitea can be supported by the leg receiving portions without difficulty. In addition, the posture change between the crushed stone position and the squatting position is in accordance with the anatomically appropriate movement of the pelvic femoral joint, so that the burden on the obstetrics and women can be further reduced. This has the advantage that the maternity woman can easily maintain an appropriate open leg, so that the doctor can easily perform various treatments.

[0023]

According to the present invention, in particular, in the transition to the second stage of labor, the leg receiving portion moved to the use position allows the mother to easily move to the crushed stone position by the leg receiving portion, and furthermore, the crushed stone position can be maintained for a long time. It will be easier. This is due to the existence of the vertical bending axis and the horizontal rotation axis that realize the bending and extension movement of the thigh, the abduction and inversion movement, and the rotation of the inside and outside. This is an effect due to the configuration of the buttocks support (the presence of a bending axis) in which the plane rises in an inclined state. And since such a posture change and maintenance are possible, in order to improve the livability of the sitting delivery table in the first stage of delivery, etc.,
In the second stage of delivery, etc., the mother can be firmly supported by the buttocks while the back plate is widened.

Further, as shown in the above-mentioned example, by having the handle provided on the leg receiving portion by the obstetrical woman, the posture can be continuously changed between the crushed position and the squatting position in accordance with the woman's strength, and The effect is more natural and greatly reduces the burden on women. Further, while the stretcher can be freely attached to and detached from the buttocks, the leg support can be moved up and down without disturbing the detachment of the stretcher, so that the first to fourth births, that is, the labor period, the delivery period, and postpartum We have made it possible to provide a sitting delivery table suitable for LDR, a method of delivery in a single room throughout the follow-up period. Thus, the present invention, on the one hand, reduces the burden on the obstetrics and, on the other hand, makes it possible to provide a sitting delivery table suitable for each treatment of the doctor.
