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 examinees such as pregnant women and parturients are examined or give birth. The delivery table is equipped with a leg support for placing the legs in a spread-eagle position, a grip for the examinee to hold when bearing down, a side fence for preventing the examinee from falling, and the like. For the delivery table, these leg supports and the like can be detachable according to the application or can be provided in advance.

[0003] For a type of delivery table in which leg supports and the like are detachable, an operator such as a doctor or midwife needs to manually replace the leg supports and the like at the part of the delivery table where the lower body of the examinee is placed. On the other hand, for a type of delivery table in which leg supports 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 1 Invention").

[0004] Prior Art 1 Invention is usually a flat bed, but during childbirth, the part of the bed where the lower body of the examinee is placed (hereinafter referred to as "lower half") is deformed to become a leg support for spreading the legs of the examinee, a baby receiving table for receiving a newborn, and the like. More specifically, in the state of the bed, the lower half is the part where the lower body of the examinee is placed, and in the state during childbirth, it is divided into a part where the legs of the examinee are placed and a part where the newborn is placed. Therefore, Prior Art 1 Invention can handle the state of the bed when the examinee simply lies down and the state during childbirth with a single delivery table.

[0005] Note that the shape of the delivery table varies. In recent years, LDR (Labor, Delivery, Recovery) has become popular, and in some cases, the patient may stay in the same room from the onset of labor to delivery and postpartum recovery. To avoid disturbing the mental stability before and after childbirth, a rounded design is preferred to eliminate the stark atmosphere of the hospital. Basically, the shape of the bed is rectangular as in the invention known from the literature 1.

Summary of the Invention

Problems to be Solved by the Invention

[0007] As described above, in the invention known from the literature 1, the state of the bed and the state during childbirth are borne by a single delivery table. Therefore, the lower half is designed to have an area that is not a problem in any state. Thus, if it is the area required in the state of the bed, even if it is overly large in the state during childbirth, it is adopted. Incidentally, if the support legs and the baby receiving table are to be appropriately attached and detached as appropriate to adopt an appropriate area in any state, as described above, it becomes impossible to quickly respond to childbirth.

[0008] Generally, from the viewpoints of safety to prevent the patient and the newborn from falling and the comfort of the patient, it is considered that the area of the delivery table is given priority to being excessive rather than insufficient. In this case, the area of the delivery table becomes relatively large. On the other hand, when the operator performs the operation around the patient, it is more convenient to be as close to the patient as possible. Therefore, if the area of the delivery table with respect to the patient is too large, the operator cannot get close to the patient to perform the operation.

[0009] The present invention has been proposed in view of the above circumstances, and an object thereof is to provide a delivery table that can achieve both a bed state and a delivery state with a single unit and realizes ease of performing a procedure.

Means for Solving the Problems

[0010] 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 the subject can lie down or a delivery state in which the subject can assume a posture during delivery, and includes a seat portion, a backrest portion that can rise or fall with respect to the seat portion, and a pair of support leg portions that are disposed on the side opposite to the backrest portion with respect to the seat portion and on which the legs of the subject that are opened left and right are placed. In the bed state, from the backrest portion through the seat portion to the support leg portions, the left and right widths of the backrest portion, the left and right widths of the seat portion, and the left and right widths of the pair of support leg portions gradually narrow.

[0011] In the bed state, a delivery table according to the present invention is characterized in that, from the backrest portion through the seat portion to the support leg portions, the right end portion of the backrest portion, the right end portion of the seat portion, and the right end portions of the pair of support leg portions are aligned in a straight line, and the left end portion of the backrest portion, the left end portion of the seat portion, and the left end portions of the pair of support leg portions are aligned in a straight line.

[0012] In the bed state, a delivery table according to the present invention is characterized in that the pair of support leg portions are adjacent to each other, and the corners on the right end side and the left end side of the pair of support leg portions are recessed more than the corner on the inner end side, which is the portion where the support leg portions face each other, among the toe end portions of the support leg portions.

[0013] A delivery table according to the present invention has handrail portions disposed at the left and right edges of the bed top surface that supports the subject, and the handrail portions can be deformed into a use state in which they protrude above the bed top surface or a non-use state in which they are stored below the bed top surface and inside the left and right edges of the bed top surface.

[0014] The delivery table according to the present invention is characterized in that the support legs open and close to the left and right.

[0015] The delivery table according to the present invention is characterized in that the handrail portion has a movable shaft member with the left - right width direction of the backrest portion as a rotation axis, and first locking means for restricting the rotation of the handrail portion with the movable shaft member as a rotation axis.

[0016] The delivery table according to the present invention is characterized in that the handrail portion has second locking means for restricting deformation from the used state to the unused state.

Advantages of the Invention

[0017] 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, 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 arranged on the side opposite to the backrest portion with respect to the seat portion and on which the legs of the subject that are opened to the left and right are placed. In the bed state, from the backrest portion through the seat portion to the support legs, the left - right width of the backrest portion, the left - right width of the seat portion, and the left - right width of the pair of support legs gradually narrow. Generally, the silhouette of a human is widest at the shoulder width and generally tapers towards the toes. The present invention also has a shape that narrows in width from the backrest portion through the seat portion to the support legs, following the silhouette of a human. That is, the distance from the edge of the delivery table to the subject is designed to be as short as possible as long as the subject can lie safely, so that the operator can approach the subject as closely as possible, and the operation becomes smooth. If the left - right width of the support legs is narrow, the support legs do not become an unnecessarily large presence even in the delivery state and do not interfere with the operation. Therefore, both the bed state and the delivery state can be achieved with one table, and ease of operation is realized.

[0018] The delivery table according to the present invention, in the bed state, from the backrest part through the seat part to the support legs, the right end part of the backrest part, the right end part of the seat part, and the right end parts of the pair of support legs are aligned in a straight line, and the left end part of the backrest part, the left end part of the seat part, and the left end parts of the pair of support legs are aligned in a straight line. That is, in the bed state, the side surfaces are aligned in a horizontal plane and there are no irregularities, so the stretcher can be brought close and moved closer.

[0019] The delivery table according to the present invention, in the bed state, the pair of support legs are adjacent to each other, and among the tip ends of the support legs, the corners on the right end side and the left end side of the pair of support legs are recessed more than the inner end side corner which is the part where the support legs face each other. Since the distance from the corners on the left and right end sides to the feet of the subject is short, the operator can approach the subject as closely as possible, and the operation becomes smooth.

[0020] The delivery table according to the present invention has handrail parts arranged on the left and right edges of the bed top surface that supports the subject, and the handrail parts are in a use state where they protrude above the bed top surface, or the handrail parts are below the bed top surface and are deformed into a non-use state where they are housed inside the left and right edges of the bed top surface. In the non-use state, the handrail parts do not protrude from the left and right edges of the bed top surface. Therefore, the stretcher can be brought close and moved closer.

[0021] The delivery table according to the present invention has support legs that open and close left and right. Therefore, in the delivery state, the posture necessary for delivery can be taken, and on the other hand, in the bed state where the support legs are closed, the necessary area can be secured within a range that does not become an excessive width.

[0022] The delivery table according to the present invention has a handrail part that has a movable shaft member with the left and right width direction of the backrest part as the rotation axis, and a first locking means that regulates the rotation of the handrail part with the movable shaft member as the rotation axis. Therefore, the handrail part is prevented from being deformed from the use state to the non-use state involuntarily.

[0023] The delivery table according to the present invention has second locking means for restricting the handrail portion from deforming from the used state to the unused state. Therefore, the handrail portion is prevented from accidentally deforming from the used state to the unused state.

Embodiments for Carrying Out the Invention

[0025] Hereinafter, the delivery table according to an embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the delivery table 1 has a lifting portion 3 installed on the installation surface, and the height changes when the lifting portion 3 operates. The delivery table 1 includes a seat portion 4, a backrest portion 6 disposed behind the seat portion 4 and rising or falling with respect to the seat portion 4, a pair of leg portions 11 disposed in front of the seat portion 4 on the side opposite to the backrest portion 6 and opening and closing left and right, grips 24 disposed on the left and right of the seat portion 4, and handrail portions 26 disposed on the left and right of the backrest portion 6.

[0026] As shown in FIGS. 1 and 2, the delivery table 1 has a lifting portion 3 installed on the installation surface, and the height changes when the lifting portion 3 operates. The delivery table 1 includes a seat portion 4, a backrest portion 6 disposed behind the seat portion 4 and rising or falling with respect to the seat portion 4, a pair of leg portions 11 disposed in front of the seat portion 4 on the side opposite to the backrest portion 6 and opening and closing left and right, grips 24 disposed on the left and right of the seat portion 4, and handrail portions 26 disposed on the left and right of the backrest portion 6.

[0027] 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 portion 4, the upper body of the subject 40 is placed on the backrest portion 6, and the legs of the subject 40 are placed on the support legs 11. The delivery table 1 deforms into the delivery state while the subject 40 is placed thereon. In the delivery state, the backrest portion 6 rises upward toward the front, and the support legs 11 open to the left and right while the legs of the subject 40 are placed thereon. Further, the handrail portion 26 also serves as a fence, and it deforms from the unused state (see FIG. 1) housed below the bed top surface 2 (the upper surface of the backrest portion 6 or the upper surface of the seat portion 4) that supports the subject 40 to the used state (see FIG. 2) exposed above the bed top surface 2. Similarly, the grip 24 also deforms between the unused state and the used state. The subject 40 appropriately grips the handrail portion 26 and the grip 24. Below the seat portion 4, a baby receiving stand 41 is housed. During childbirth, after it protrudes forward and the support legs 11 open, it appears below the position where the support legs 11 were before opening and appropriately receives the newborn.

[0028] 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 the unused state, and the handrail portion 26 of the delivery table 1 shown in FIGS. 7 to 9 is in the used state.

[0029] As shown in FIG. 3, in the delivery table 1 in the bed state, from the backrest portion 6 through the seat portion 4 to the support legs 11, the right end portion 12a of the backrest portion 6, the right end portion 12b of the seat portion, and the right end portion 12c of the support legs 11 are aligned in a straight line. Similarly, 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. 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 side surfaces are flush and there are no irregularities. The delivery table 1 gradually narrows in the left - right width from the backrest portion 6 through the seat portion 4 to the support legs 11, that is, 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. 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.

[0030] 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 finger of the subject 40.

[0031] 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) on which the finger of the subject 40 catches, is formed on the back surface of the protrusion 8. The recessed portion or the bulging portion is formed at the upper end or the left and right end portions 12a and 13a of the protrusion 8. Note that the recessed portion or the bulging portion may be formed at the upper end and the side end 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 end portions 12a and 13a of the protrusion 8.

[0032] 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 inward 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.

[0033] The support leg portion 11 is divided into front and rear parts, and has a front - end member 18 including the toe - tip portion 15 at the front side and a base - end member 19 including the leg - base end portion 16 at the rear side. 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.

[0034] 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 curved in an arc shape.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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 oriented 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.

[0039] The connecting main body member 30 is hollow, locking grooves 37 are formed on the front and rear surfaces, 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 with respect 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.

[0040] 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 accommodated on the back side of the backrest portion 6 (see FIGS. 5 and 6), and rotation is restricted. At that time, the pin member 34 is loosened, and the screw portion 36 does not contact the protrusion 32 (and the movable shaft member 31).

[0041] 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).

[0042] 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.

[0043] 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.

[0044] Note that if the reverse operation to the above is performed, it deforms from the use state to the non-use state.

[0045] 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.

[0046] 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.

[0047] Note that at the leg base end portion 16, the portion where the sole is placed 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.

[0048] As described above, the delivery table 1 is configured. Next, the operation and effects of the delivery table 1 will be described.

[0049] In the bed state, the delivery table 1 according to this embodiment gradually narrows in the left - right width from the backrest portion 6, through the seat portion 4, to the support legs 11 (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 in one unit, realizing ease of operation.

[0050] 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 sides are aligned in a horizontal plane without unevenness, so the stretcher can be brought close and moved closer.

[0051] In the delivery table 1 according to the present embodiment, among the toe end portions 15 at 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 and 17d on the inner end portion 14 side (see Fig. 3). Since the distance between the corners 17a and 17b on the left and right end portions 12c and 13c sides and the feet of the subject 40 is short, the operator can approach the subject 40 as closely as possible, and the operation becomes smooth.

[0052] In the delivery table 1 according to the present embodiment, the handrail portions 26 in the unused state are 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, and are stored on the back side of the backrest portion 6 and do not protrude outward from the left and right end portions 12a and 13a of the backrest portion 6 (see Figs. 4 to 6). Therefore, the stretcher can be brought close and moved closer.

[0053] 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, and the handrail portion 26 is housed on the back side of the backrest portion 6 and its rotation is restricted. Therefore, the handrail portion 26 is prevented from being unintentionally deformed from the used state to the unused state.

[0054] In the delivery table 1 according to the present embodiment, the second locking means is realized by a 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, the handrail portion 26 is prevented from being involuntarily deformed from the use state to the non-use state.

[0055] In the delivery table 1 according to the present embodiment, the backrest 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 a crawling posture, since there is a protrusion 8 at the tip of the arm extended forward, the subject 40 can grip the protrusion 8. Therefore, it is possible to cope with childbirth in a crawling posture. In addition, due to the recess 9, the operator and the person attending the delivery can approach the subject 40.

[0056] In the delivery table 1 according to the present embodiment, the thicknesses of the protrusion 8 and the recess 9 are formed to be 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 grip. Furthermore, the thickness of the protrusion 8 is such that it can be gripped 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 grip, and the subject 40 can firmly grip the protrusion 8 with the fingertips.

[0057] In the delivery table 1 according to the present embodiment, a depression portion having a shape imitating the shape of the fingertips of the fingers of the subject 40, or a swelling portion on which the fingers of the subject 40 can catch, is formed on the back surface of the protrusion 8. Therefore, the subject 40 can grip the depression portion or the swelling portion. Furthermore, the depression portion 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 grip the depression portion or the swelling portion from various directions.

[0058] In the delivery table 1 according to this embodiment, since the protrusion 8 protrudes from the back tip 7 of the backrest 6 of the backrest part (see FIG. 3 etc.), a delivery instrument (for example, tracheal intubation, pelvic basin, cannula, bag-valve-mask, etc., all of which are not shown) used when the body of the subject 40 suddenly changes is caught. Therefore, it is convenient for the operator to use the delivery instrument.

[0059] In the delivery table 1 according to this embodiment, the base end member 19 of the support leg part 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 connection part, the flat contact surface part 22 formed at the leg base end part 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 part 22 (see FIG. 15). The position of the leg base end part 16 is higher than the position where the subject 40 places the leg 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 part 22, a posture of bending both knees and bringing the thighs closer to the abdomen is promoted. Therefore, it is possible to cope even during delivery in the McRoberts position.

[0060] In the delivery table 1 according to this embodiment, a footrest protrusion 23 protruding toward the seat part 4 is formed at the leg base end part 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 part 22, the foot is caught by the footrest protrusion 23, so the foot does not slide from the leg base end part 16 to the inner end part 14 side. Therefore, the posture in the McRoberts position can be stabilized.

[0061] In the delivery table 1 according to this embodiment, the footrest protrusion 23 has a shape following the depression of the seat end part 5 of the seat part 4 (see FIG. 3). The seat end part 5 of the seat part 4 is recessed to facilitate the operation during delivery and the reception of the newborn. In the bed state, this depression becomes a hole. However, since the footrest 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.

[0062] In other embodiments of the present invention, the tip of the foot is not inclined and is straight in the left-right direction. In still another embodiment, in the bed state of the delivery table, from the backrest portion through the seat portion to the leg support portions, the right end portion of the backrest portion, the right end portion of the seat portion, and the right end portion of the leg support portions are not aligned in a straight line, and the left end portion of the backrest portion, the left end portion of the seat portion, and the left end portions of the pair of leg support portions are not aligned in a straight line. That is, in this embodiment, there are irregularities at each right end portion and / or each left end portion. In still another embodiment, in the bed state, the pair of leg support portions are not adjacent to each other, and there is a baby receiving table between the leg support portions. In still another embodiment, the leg support portions do not open and close. In still another embodiment, in the non-use state, the handrail portion is stored below the bed top surface, but is outside the left and right edges of the bed top surface. In still another embodiment, in the use state, only the handrail portion (excluding the grip) protrudes above the bed top surface, and in the non-use state, only the handrail portion (excluding the grip) is stored below the bed top surface. In still another embodiment, in the bed state, the handrail portion is in the use state, and in the delivery state, the handrail portion is in the non-use state. In still another embodiment, the handrail portion is disposed on the side of the seat portion. In still another embodiment, there is no handrail portion, and the handrail portion is manually attached and detached. In still another embodiment, the handrail portion does not have the first locking means. In still another embodiment, the handrail portion does not have the second locking means. In still another embodiment, the handrail portion does not have the first locking means and the second locking means. In still another embodiment, as the second locking means, a pin member is operated so that the screw portion hits the movable shaft member, thereby restricting the movement of the movable shaft member in the longitudinal direction. In still another embodiment, the backrest portion has the same thickness of the protrusion as the back surface portion. In still another embodiment, the backrest portion does not have a recessed portion and a bulging portion. In another embodiment, the backrest portion does not have a protrusion and a recess. In another embodiment, the support leg portion does not have a contact surface portion. In another embodiment, the seat portion has no recessed seat portion ends, and the support leg portion does not have a footrest protrusion.

[0063] Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above embodiments. And the present invention can be subjected to various design changes without departing from the matters described in the claims.
