Description

Technical Field

[0001] The present invention relates to a delivery table.

Background Art

[0002] Conventionally, in medical facilities, a delivery table has been used when examining or delivering a person to be treated such as a pregnant woman or a parturient woman. The delivery table is equipped with a leg support for placing the legs in a spread-eagle position, a grip for the person to hold when pushing, a side fence for preventing the person from falling, and the like. For the delivery table, these leg supports and the like can be attached and detached according to the application, or can be provided in advance.

[0003] For a delivery table of the type in which the leg support and the like are attached and detached, an operator such as a doctor or a midwife needs to manually replace the leg support and the like at the part where the lower body of the person to be treated is placed on the delivery table. On the other hand, for a delivery table in which the leg support and the like are provided in advance, since there is no such trouble, it is possible to quickly respond to childbirth. As such, for example, there is an invention related to a delivery table described in Patent Document 1 below (hereinafter referred to as "Prior Art Known Invention 1").

[0004] Prior Art Known Invention 1 is usually a flat bed, but it deforms during childbirth, and the part of the bed where the lower body of the person to be treated is placed becomes a leg support for spreading the legs of the parturient woman, a baby receiving table for receiving a newborn baby, and the like.

Summary of the Invention

Problems to be Solved by the Invention

[0006] Generally, the posture of the subject during childbirth is the supine position. Rarely, however, the subject may have to assume the McRoberts position. The McRoberts position is one in which both knees are bent and the thighs are brought closer to the abdomen than in the normal childbirth position. At the position of the leg support device in the supine position, the McRoberts position cannot be promoted. Although it would be possible to control the movement of the leg support device to a position where the McRoberts position can be assumed, the mechanical structure and operation would become complex, and the manufacturing costs would also increase.

[0007] The present invention has been proposed in view of the above circumstances, and an object thereof is to provide a delivery table that can also cope with childbirth in the McRoberts position.

Means for Solving the Problems

[0008] In order to achieve the above object, a delivery table according to the present invention is a delivery table that can be deformed into a bed state in which a subject can lie down or a delivery state in which a subject can assume a childbirth position, and includes a seat portion, a backrest portion that rises or falls with respect to the seat portion, and a pair of support legs that are disposed on the opposite side of the seat portion from the backrest portion and open and close left and right with the legs of the subject placed thereon. Among the support legs, a contact surface portion against which the subject places the sole of the foot is formed at the leg base end portion that faces the seat portion in the bed state.

[0009] The delivery table according to the present invention is characterized in that a footrest protrusion protruding toward the seat portion is provided on the inner end portion side, which is a portion where the support legs face each other, among the leg base end portions.

[0010] The delivery table according to the present invention is characterized in that the leg base end portion has a shape following the depression of the seat end portion that faces the footrest protrusion in the seat portion in the bed state.

Effects of the Invention

[0011] The delivery table according to the present invention is a delivery table that can be deformed into a bed state in which the subject can lie down or a delivery state in which the subject can assume a delivery posture. It has a seat part, a backrest part that can rise or fall with respect to the seat part, and a pair of support legs that are arranged on the side opposite to the backrest part with respect to the seat part and open and close left and right with the subject's legs placed thereon. Among the support legs, an abutting surface part where the subject places the sole of the foot is formed at the leg base end part that faces the seat part in the bed state. The position of the support legs in the delivery state is the same as that during delivery in the supine position, but the position of the leg base end part is higher than the position where the subject places the legs in the supine position and is closer to the subject. Therefore, when the sole of the foot is placed on the abutting surface part, a posture of bending both knees and bringing the thighs closer to the abdomen is promoted. Thus, it can also cope with delivery in the McRoberts position posture.

[0012] The delivery table according to the present invention has a footrest protrusion that protrudes toward the seat part on the inner end part side, which is the part where the support legs face each other among the leg base end parts. In the McRoberts position, since the foot is caught on the footrest protrusion, the foot does not slide from the leg base end part to the inner end part side. Thus, the posture in the McRoberts position can be stabilized.

[0013] The leg base end part of the delivery table according to the present invention has a shape that follows the depression in the seat part end part that faces the footrest protrusion in the seat part in the bed state. The seat part end part of the seat part is recessed to facilitate the operation during delivery and the reception of the newborn. Therefore, in the bed state, this depression becomes a hole, but in the present invention, since the leg base end part has a shape that follows the depression, the hole is blocked even in the bed state. Thus, in addition to being able to cope with delivery in the McRoberts position posture, an appropriate bed state can be realized.

Embodiments for Carrying Out the Invention

[0015] Hereinafter, the delivery table according to the embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, a delivery table 1 in a bed state in which the subject 40 (see FIG. 15) can lie down is shown. As shown in FIG. 2, a delivery table 1 in a delivery state in which the subject 40 can assume a delivery posture is shown. Hereinafter, the height direction of the delivery table 1 is defined as upward or downward (Up, Down), the entire length direction of the delivery table 1 is defined as forward or backward (Fron, Back), and the width direction of the delivery table 1 is defined as left or right (Left, Right) (see FIGS. 1 and 2).

[0016] As shown in FIGS. 1 and 2, the delivery table 1 has a lifting part 3 installed on the installation surface, and the height changes when the lifting part 3 operates. The delivery table 1 includes a seat part 4, a backrest part 6 arranged behind the seat part 4 and rising or falling with respect to the seat part 4, a pair of support legs 11 arranged in front of the seat part 4 on the side opposite to the backrest part 6 and opening and closing left and right, grips 24 arranged on the left and right of the seat part 4, and handrails 26 arranged on the left and right of the backrest part 6.

[0017] When the subject 40 lies on the delivery table 1 in the bed state, the buttocks of the subject 40 are placed on the seat part 4, the upper body of the subject 40 is placed on the backrest part 6, and the legs of the subject 40 are placed on the support legs 11. The delivery table 1 deforms into the delivery state with the subject 40 on it. In the delivery state, the backrest part 6 rises forward, and the support legs 11 open left and right while supporting the legs of the subject 40. Further, the handrail part 26 also serves as a fence, and changes from an unused state (see FIG. 1) accommodated below the bed top surface 2 (the upper surface of the backrest part 6 or the upper surface of the seat part 4) that supports the subject 40 to a used state exposed above the bed top surface 2 (see FIG. 2). Similarly, the grip 24 also deforms between the unused state and the used state. The subject 40 appropriately grips the handrail part 26 and the grip 24. Below the seat part 4, a baby receiving table 41 is accommodated. During delivery, after protruding forward and the support legs 11 are opened, it appears below the position where the support legs 11 were before opening, and appropriately receives the newborn.

[0018] The delivery table 1 will be further described in detail with reference to the drawings. FIGS. 3 to 9 show the delivery table 1 in the bed state. The handrail portion 26 of the delivery table 1 shown in FIGS. 4 to 6 is in a non-use state, and the handrail portion 26 of the delivery table 1 shown in FIGS. 7 to 9 is in a use state.

[0019] As shown in FIG. 3, in the bed state, the delivery table 1 extends from the backrest portion 6 through the seat portion 4 to the support legs 11, and the right end 12a of the backrest portion 6, the right end 12b of the seat portion, and the right end 12c of the support legs 11 are aligned in a straight line. Similarly, extending from the backrest portion 6 through the seat portion 4 to the support legs 11, the left end 13a of the backrest portion 6, the left end 13b of the seat portion 4, and the left ends 13c of the pair of support legs 11 are aligned in a straight line. Except for the gaps between the backrest portion 6 and the seat portion 4 and between the seat portion 4 and the support legs 11, the sides are flush and there are no irregularities. The delivery table 1 extends from the backrest portion 6 through the seat portion 4 to the support legs 11, and the left and right widths of the backrest portion 6, the left and right widths of the seat portion 4, and the left and right widths of the pair of support legs 11 gradually narrow. Therefore, when viewed from above, the delivery table 1 is generally rectangular but approximates a fan shape or an inverted triangle and is different from a rectangle with parallel sides.

[0020] Among the backrest portion 6, the backrest tip portion 7, which is the rear tip, has a pair of left and right protrusions 8 protruding rearward and a recess 9 formed between the protrusions 8. As shown in FIGS. 4 and 5, the thicknesses of the protrusions 8 and the recess 9 are formed thinner than the peripheral portions such as the back surface portion 10 connected to the protrusions 8 and the recess 9. Specifically, the thicknesses of the protrusions 8 and the recess 9 are such that they can be gripped by the third joint and the second joint or the first joint of the fingers of the subject 40.

[0021] On the back surface of the protrusion 8, a recessed portion (not shown) having a shape imitating the shape of the fingertip of the finger of the subject 40 or a bulging portion (not shown) for the finger of the subject 40 to catch is formed. The recessed portion or the bulging portion is formed at the upper end or the left and right ends 12a, 13a of the protrusion 8. Note that the recessed portion or the bulging portion may be formed at the upper end and the side ends of the protrusion 8, or both the recessed portion and the bulging portion may be formed at the upper end or the left and right ends 12a, 13a of the protrusion 8.

[0022] As shown in FIG. 3, the seat portion 4 is formed wider in the left - right width than in the front - rear length. Among the seat portion 4, the seat end portion 5 facing the support leg portion 11 in the bed state is recessed inwardly in a concave shape. The pair of support leg portions 11 are formed longer in the front - rear length than in the left - right width and are adjacent to each other in the bed state. The length of the support leg portion 11 is shorter on the right - end portion 12c side and the left - end portion 13c side of the support leg portion 11 than on the inner - end portion 14 side which is the portion where the support leg portions 11 face each other. In other words, among the toe - tip portions 15 which are the front ends of the support leg portions 11, the corners 17c and 17d on the inner - end portion 14 side protrude forward more than the corners 17a on the right - end portion 12c side and the corners 17b on the left - end portion 13c side, and the corners 17a on the right - end portion 12c side and the corners 17b on the left - end portion 13c side are recessed inward more than the corners 17c and 17d on the inner - end portion 14 side. The corners 17a on the right - end portion 12c side and the corners 17b on the left - end portion 13c side are obtuse angles, and the corners 17c and 17d on the inner - end portion 14 side are acute angles. Therefore, the toe - tip portion 15 slopes inward from the inner - end portion 14 side to the right - end portion 12c side and the left - end portion 13c side. Also, among the leg - base end portions 16 which are the rear ends of the support leg portions 11 and face the seat end portion 5 of the seat portion 4 in the bed state, the inner - end portion 14 side protrudes toward the seat portion 4.

[0023] The support leg portion 11 is divided into front and rear parts, and has a front - end member 18 which is the front side and includes the toe - tip portion 15, and a base - end member 19 which is the rear side and includes the leg - base end portion 16. The base - end member 19 is further divided into left and right parts, and has an outer - side leg member 20 on the left - and right - end portions 12c, 13c sides and an inner - side leg member 21 on the inner - end portion 14 side. A contact surface portion 22 is formed on the leg - base end portion 16 of the outer - side leg member 20 (see FIGS. 13 and 14 described later). A foot - hanging protrusion 23 protruding toward the seat portion 4 is formed on the leg - base end portion 16 of the inner - side leg member 21. The foot - hanging protrusion 23 has a shape following the depression of the seat end portion 5 of the seat portion 4.

[0024] As shown in FIGS. 4 to 6, the handrail portion 26 in the unused state is stored below the bed top surface 2 and inside the left and right edges of the bed top surface 2 at the left and right end portions 12a and 13a of the backrest portion 6. In other words, the handrail portion 26 is stored on the back side of the backrest portion 6 and does not protrude outward from the left and right end portions 12a and 13a of the backrest portion 6. The handrail portion 26 is generally elliptical and has a fence portion 27 and a handrail main body portion 28 connected to the fence portion 27. The fence portion 27 in the unused state occupies more than the upper half of the handrail portion 26, and the handrail main body portion 28 occupies less than the lower half of the handrail portion 26. The fence portion 27 is plate-shaped and a handrail portion rotating member 29 (see FIGS. 10 to 12 described later) is connected thereto. The handrail main body portion 28 is rod-shaped and is curved in an arc shape.

[0025] The grip 24 in the unused state is stored below and inside the left and right edges of the bed top surface 2. In other words, the grip 24 is stored on the back side of the seat portion 4 and does not protrude outward from the left and right end portions 12b and 13b of the seat portion 4. The grip 24 is rod-shaped, is connected to the back side of the seat portion 4, and rotates about the base side as an axis.

[0026] As shown in FIGS. 7 to 9, the handrail portion 26 in the used state is disposed on the left and right sides of the backrest portion 6 and protrudes above the left and right edges of the bed top surface 2. The fence portion 27 in the used state occupies more than the lower half of the handrail portion 26, and the handrail main body portion 28 occupies less than the upper half of the handrail portion 26. The grip 24 in the used state is disposed on the side of the seat portion 4 and protrudes above the left and right edges of the bed top surface 2.

[0027] Next, the handrail portion rotating member 29 will be described with reference to the drawings. FIGS. 10 to 12 show the handrail portion 26 and the handrail portion rotating member 29. The handrail portion 26 shown in FIGS. 10 and 11 is in the unused state, and the handrail portion 26 shown in FIG. 12 is in the used state.

[0028] As shown in FIGS. 10 to 12, the handrail portion rotating member 29 includes a rectangular parallelepiped connecting main body member 30, a rod-shaped movable shaft member 31 passed through the connecting main body member 30, a first locking means 33 constituted by the connecting main body member 30 and the movable shaft member 31, and a pin member 34 as a second locking means provided on the connecting main body member 30. The handrail portion rotating member 29 is arranged such that the longitudinal direction of the movable shaft member 31 is aligned in the left-right direction, and the connecting main body member 30 is fixed to the back surface of the backrest portion 6.

[0029] The connecting main body member 30 is hollow, locking grooves 37 are formed on the front surface and the rear surface, and the pin member 34 is attached to the lower surface. The locking grooves 37 extend in the longitudinal direction of the connecting main body member 30, and one locking groove 37 is formed longer than the other locking groove 37. The shorter one is the positioning locking groove 38 in the use state (see FIG. 12), and the longer one is the positioning locking groove 39 in the non-use state (see FIG. 11). The pin member 34 has a handle portion 35 and a screw portion 36, and the screw portion 36 penetrates the lower surface of the connecting main body member 30 inward. The movable shaft member 31 is movable relative to the connecting main body member 30. A protrusion 32 that locks into the locking groove 37 is fixed to the outer surface of the movable shaft member 31.

[0030] The first locking means 33 is realized by the locking groove 37 of the connecting main body member 30 and the protrusion 32 of the movable shaft member 31, and the second locking means is realized by the pin member 34 provided on the connecting main body member 30. That is, as shown in FIGS. 10 and 11, in the non-use state, since the protrusion 32 of the movable shaft member 31 is locked in the non-use state positioning locking groove 39, the movable shaft member 31 is deeply inserted into the connecting main body member 30. Therefore, the handrail portion 26 is housed on the back side of the backrest portion 6 (see FIGS. 5 and 6), and rotation is restricted. At this time, the pin member 34 is loosened, and the screw portion 36 does not contact the protrusion 32 (and the movable shaft member 31).

[0031] In the non-use state, when the handrail part 26 is pulled out, at the same time, the movable shaft member 31 is pulled out from the connecting main body member 30 and the protrusion 32 comes out of the non-use state positioning locking groove 39. When the protrusion 32 comes out of the non-use state positioning locking groove 39, the movable shaft member 31 becomes rotatable. When the handrail part 26 rotates 180 degrees with the movable shaft member 31 as the rotation axis, at the same time, the protrusion 32 is aligned with the use state positioning locking groove 38. As shown in FIG. 12, when the handrail part 26 is pushed, at the same time, the movable shaft member 31 is inserted into the connecting main body member 30 and the protrusion 32 is locked in the use state positioning locking groove 38. Therefore, the handrail part 26 is arranged on the left and right sides of the backrest part 6 and protrudes above the left and right edges of the bed top surface 2 (see FIGS. 8 and 9).

[0032] In this way, by the first locking means 33, the rotation of the handrail part 26 in the use state and the non-use state is restricted, and since the handrail part 26 becomes immovable, the deformation to the use state or the non-use state is restricted.

[0033] As shown in FIG. 12, in the use state, when the pin member 34 is operated and the screw part 36 hits the protrusion 32, the movement of the movable shaft member 31 in the longitudinal direction is restricted. In this way, by the second locking means, the pulling out of the handrail part 26 in the use state is restricted, and since the handrail part 26 becomes immovable, the deformation from the use state to the non-use state is restricted. Note that the second locking means can also restrict the pulling out of the handrail part 26 in the non-use state and restrict the deformation from the non-use state to the use state.

[0034] Note that if the reverse operation to the above is performed, it deforms from the use state to the non-use state.

[0035] Next, the support legs 11 in the delivery state will be described with reference to the drawings. FIGS. 13 and 14 show the support legs 11 in the delivery state.

[0036] As shown in FIGS. 13 and 14, in the delivery state, the support legs 11 are in a V-shaped posture where the tip member 18 and the base member 19 rise from their connection part with respect to the bed top surface 2. Further, in the base member 19, the outer leg member 20 rises from its connection part with respect to the inner leg member 21, resulting in a V-shaped posture. A flat contact surface portion 22 is formed at the leg base end portion 16 of the outer leg member 20. Since it has an appropriate thickness, as shown in FIG. 15, the sole of the subject 40 can be placed thereon. At the leg base end portion 16 of the inner leg member 21, a foot hook protrusion 23 protrudes. Since it has an appropriate thickness, the foot can be hooked on the foot hook protrusion 23.

[0037] Note that the portion where the sole is placed at the leg base end portion 16 is arbitrary because it is selected by the subject 40. Therefore, for example, among the leg base end portions 16 of the inner leg member 21, the portion where the foot hook protrusion 23 is not formed (the portion lower than the foot hook protrusion 23 and in the same plane as the contact surface portion 22) or the foot hook protrusion 23 may have the sole placed thereon. Also, during normal delivery, the sole is placed on the upper surface of the tip member 18.

[0038] As described above, the delivery table 1 is configured. Next, the operation and effects of the delivery table 1 will be described.

[0039] In the bed state, the delivery table 1 according to the present embodiment gradually narrows in width from the backrest portion 6 through the seat portion 4 to the support legs 11, i.e., the left - right width of the backrest portion 6, the left - right width of the seat portion 4, and the left - right width of the pair of support legs 11 gradually narrow (see FIG. 3). That is, as long as the space between the edge of the delivery table 1 and the subject 40 allows the subject 40 to lie safely without falling, etc., it is designed to be as short as possible. Therefore, the operator can approach the subject 40 as closely as possible, making the operation smooth. If the left - right width of the support legs 11 is narrow, the support legs 11 will not be an unnecessarily large presence even in the delivery state and will not interfere with the operation. Thus, the bed state and the delivery state can coexist with one table, realizing easy operation.

[0040] In the bed state, the delivery table 1 according to the present embodiment extends from the backrest portion 6 through the seat portion 4 to the support legs 11, and the right end portion 12a of the backrest portion 6, the right end portion 12b of the seat portion 4, and the right end portions 12c of the pair of support legs 11 are aligned in a straight line. Similarly, extending from the backrest portion 6 through the seat portion 4 to the support legs 11, the left end portion 13a of the backrest portion 6, the left end portion 13b of the seat portion 4, and the left end portions 13c of the pair of support legs 11 are aligned in a straight line (see Fig. 3). Therefore, in the bed state, the side surfaces are aligned in a horizontal plane without irregularities, so the stretcher can be brought close and moved closer.

[0041] In the delivery table 1 according to the present embodiment, among the toe end portions 15 which are the front ends of the support legs 11, the corners 17a on the right end portion 12c side and the corners 17b on the left end portion 13c side are recessed inward more than the corners 17c, 17d on the inner end portion 14 side (see Fig. 3). Since the distance from the corners 17a, 17b on the left and right end portions 12c, 13c sides to the feet of the subject 40 is short, the operator can approach the subject 40 as closely as possible, and the operation becomes smooth.

[0042] In the delivery table 1 according to the present embodiment, the handrail portion 26 in the unused state is stored below the bed top surface 2 and inside the left and right edges of the bed top surface 2 at the left and right end portions 12a, 13a of the backrest portion 6, is stored on the back side of the backrest portion 6, and does not protrude outward from the left and right end portions 12a, 13a of the backrest portion 6 (see Figs. 4 to 6). Therefore, the stretcher can be brought close and moved closer.

[0043] In the delivery table 1 according to the present embodiment, the first locking means 33 is realized by the locking groove 37 of the connecting main body member 30 and the protrusion 32 of the movable shaft member 31 (see Figs. 10 and 11). With this configuration, in the unused state, since the protrusion 32 of the movable shaft member 31 is locked in the unused state positioning locking groove 39, the movable shaft member 31 is deeply inserted into the connecting main body member 30, the handrail portion 26 is accommodated on the back side of the backrest portion 6, and rotation is restricted. Therefore, the handrail portion 26 is prevented from being deformed unintentionally from the used state to the unused state.

[0044] In the delivery table 1 according to this embodiment, the second locking means is realized by the pin member 34 (see FIG. 12). In the use state, when the pin member 34 is operated and the threaded portion 36 hits the protrusion 32, the movement of the movable shaft member 31 in the longitudinal direction is restricted. Therefore, it is possible to prevent the handrail portion 26 from being inadvertently deformed from the use state to the non-use state.

[0045] In the delivery table 1 according to this embodiment, the back tip portion 7 of the backrest portion 6 has a pair of left and right protrusions 8 protruding rearward and a recess 9 formed between the protrusions 8 (see FIG. 3). If the subject 40 kneels on the seat portion 4 in the crawling posture, since the protrusion 8 is at the tip of the arm extended forward, the subject 40 can grasp the protrusion 8. Therefore, it is possible to cope with childbirth in the crawling posture. In addition, due to the recess 9, the operator and those attending the delivery can approach the subject 40.

[0046] In the delivery table 1 according to this embodiment, the thicknesses of the protrusion 8 and the recess 9 are formed thinner than the peripheral portions such as the back surface portion 10 connected to the protrusion 8 and the recess 9 (see FIGS. 4 and 5). Therefore, the protrusion 8 is easy for the subject 40 to grasp. Further, the thickness of the protrusion 8 is such that it can be grasped by the third joint and the second joint or the first joint of the fingers of the subject 40. Therefore, the protrusion 8 is even easier for the subject 40 to grasp, and the subject 40 can firmly grasp the protrusion 8 with the fingertips.

[0047] In the delivery table 1 according to this embodiment, a recess having a shape imitating the shape of the fingertip of the finger of the subject 40, or a swelling portion on which the finger of the subject 40 catches is formed on the back surface of the protrusion 8. Therefore, the subject 40 can grasp the recess or the swelling portion. Further, the recess or the swelling portion is formed at the upper end or the left and right end portions 12a, 13a of the protrusion 8. Therefore, the subject 40 can grasp the recess or the swelling portion from various directions.

[0048] In the delivery table 1 according to the present embodiment, since the protrusion 8 protrudes from the back tip 7 of the backrest portion 6 (see FIG. 3 etc.), when the body of the subject 40 undergoes a sudden change, a delivery instrument (for example, tracheal intubation, pelvic basin, cannula, bag-valve-mask, etc., all of which are not shown) can be hooked. Therefore, it is convenient for the operator to use the delivery instrument.

[0049] In the delivery table 1 according to the present embodiment, the base end member 19 of the leg support portion 11 is divided into an outer leg member 20 and an inner leg member 21. In the delivery state, when the outer leg member 20 rises with respect to the inner leg member 21 starting from their connecting portion, the flat contact surface portion 22 formed at the leg base end portion 16 of the outer leg member 20 appears (see FIGS. 13 and 14). The sole of the foot of the subject 40 is placed on the contact surface portion 22 (see FIG. 15). The position of the leg base end portion 16 is higher than the position where the subject 40 places the legs in the supine position and is also closer to the subject 40. Therefore, when the sole of the foot is placed on the contact surface portion 22, a posture of bending both knees and bringing the thighs closer to the abdomen is promoted. Thus, it is possible to cope even during delivery in the McRoberts position.

[0050] In the delivery table 1 according to the present embodiment, a foot hook protrusion 23 protruding toward the seat portion 4 is formed at the leg base end portion 16 of the inner leg member 21 (see FIG. 3). In the McRoberts position, when the sole of the foot of the subject 40 is placed on the contact surface portion 22, the foot is hooked on the foot hook protrusion 23, so that the foot does not slide from the leg base end portion 16 toward the inner end portion 14 side. Therefore, the posture in the McRoberts position can be stabilized.

[0051] In the delivery table 1 according to the present embodiment, the foot hook protrusion 23 has a shape following the depression of the seat end portion 5 of the seat portion 4 (see FIG. 3). The seat end portion 5 of the seat portion 4 is recessed in order to facilitate the operation during delivery and the reception of the newborn. In the bed state, this depression becomes a hole. However, since the foot hook protrusion 23 has a shape following the depression, the hole is blocked even in the bed state. Therefore, in addition to being able to cope even during delivery in the McRoberts position, an appropriate bed state can be realized.

[0052] In other embodiments of the present invention, the tip of the foot is not inclined and is straight in the left-right direction. In yet another embodiment, in the bed state, the delivery table, from the backrest part through the seat part to the support legs, the right end of the backrest part, the right end of the seat part, and the right end of the support legs are not aligned in a straight line, and the left end of the backrest part, the left end of the seat part, and the left ends of the pair of support legs are not aligned in a straight line. That is, in this embodiment, there are irregularities at each right end or / and each left end. In yet another embodiment, in the bed state, the pair of support legs are not adjacent to each other, and there is a baby receiving table between the support legs. In yet another embodiment, the support legs do not open and close. In yet another embodiment, in the non-use state, the handrail part is stored below the bed top surface but outside the left and right edges of the bed top surface. In yet another embodiment, in the use state, only the handrail part (excluding the grip) protrudes above the bed top surface, and in the non-use state, only the handrail part (excluding the grip) is stored below the bed top surface. In yet another embodiment, in the bed state, the handrail part is in the use state, and in the delivery state, the handrail part is in the non-use state. In yet another embodiment, the handrail part is arranged on the side of the seat part. In yet another embodiment, there is no handrail part, and the handrail part is manually attached and detached. In yet another embodiment, the handrail part does not have the first locking means. In yet another embodiment, the handrail part does not have the second locking means. In yet another embodiment, the handrail part does not have the first locking means and the second locking means. In yet another embodiment, as the second locking means, when the pin member is operated and the screw part hits the movable shaft member, the movement of the movable shaft member in the longitudinal direction is restricted. In yet another embodiment, the backrest part has the same thickness of the protrusion as the back surface part. In yet another embodiment, the backrest part does not have a recessed part and a bulging part. In another embodiment, the backrest portion does not have a protrusion and a recess. In another embodiment, the seat portion does not have a recessed seat end, and the support leg portion does not have a footrest protrusion.
