[0003] [Patent Document 1] Japanese Patent Application Publication No. 10-33569 Summary of the Invention [Problem to be solved by the invention]

[0004] A typical dental treatment table is designed to accommodate right-handed dentists, but there is a demand for a treatment table that can accommodate left-handed dentists. Here, if a left-handed examination table is prepared in addition to a right-handed examination table to accommodate left-handed dentists, it will be necessary to prepare separate parts for the right-handed examination table and parts for the left-handed examination table, which will require time and effort in managing the parts. An object of the present invention is to make it possible to accommodate both right-handed and left-handed doctors with a single examination table. [Means for solving the problem]

[0005] With this objective in mind, the examination table to which the present invention is applicable is a dental examination table that supports a patient from below, and comprises a support part that supports a patient lying on his / her back from below, a one-side attachment part that is positioned in one of two areas that extend vertically through a center line along the longitudinal direction of the support part and face each other across a vertical plane, to which an attachment is attached, and a other-side attachment part that is positioned in the other of the two areas to which an attachment is attached, and is configured so that a common attachment can be attached to the one-side attachment part and the other-side attachment part.

[0006] Here, the other-side mounting portion may be located on a straight line passing through the one-side mounting portion and perpendicular to the vertical plane. The distance between the one-side mounting portion and the vertical surface may be equal to the distance between the other-side mounting portion and the vertical surface. The common mounting body may be characterized by comprising a fixed portion fixed to each of the one-side mounting portion and the other-side mounting portion, and a movable portion movable relative to the fixed portion. Furthermore, the moving part may be provided with an object support stand that supports the object from below, and by moving the object support stand of the common mounting body fixed to the one-side mounting part or the other-side mounting part, the position of the object support stand relative to the support part can be changed. The common attachment body can also be characterized in that it is provided with a first fixed portion fixed to the one-side attachment portion, and a second fixed portion provided at a location different from the first fixed portion and fixed to the other-side attachment portion. Moreover, the common mounting body can be characterized in having at least two surfaces, a first surface and a second surface arranged opposite the first surface, and in that the first fixed portion is provided on one surface side of the two surfaces, and the second fixed portion is provided on the other surface side.

[0007] The present invention can also be characterized in that mounting members are attached to the common mounting body, and that the mounting members can be attached to a plurality of locations on the common mounting body. It can also be characterized in that the attitude of the mounting member relative to the common mounting body when the mounting member is attached to one mounting point of the common mounting body is different from the attitude of the mounting member relative to the common mounting body when the mounting member is attached to another mounting point. The common mounting body may be provided with a support portion for supporting a medical instrument, and the position of the support portion relative to the common mounting body may be changed. The common mounting body may be provided with a first support part for supporting a first medical instrument and a second support part for supporting a second medical instrument, and the first support part and the second support part may be provided so that the first medical instrument supported by the first support part and the second medical instrument supported by the second support part are not parallel to each other. The present invention can also be characterized in that the attitude of one of the first support portion and the second support portion relative to the other support portion can be changed. It can also be characterized in that even when the posture of the other support part is changed, the first medical instrument supported by the first support part and the second medical instrument supported by the second support part do not become parallel to each other. The common attachment body can be used to support piping extending from the support portion toward a medical instrument, and the piping can extend from a central portion of the support portion in a short direction that is perpendicular to the longitudinal direction of the support portion toward the medical instrument. It can also be characterized in that, with one surface of the common attachment body facing the one-side attached portion, the common attachment body is rotated in one direction to attach the common attachment body to the one-side attached portion, and, with the other surface of the common attachment body facing the other-side attached portion, the common attachment body is rotated in one direction to attach the common attachment body to the other-side attached portion. It can also be characterized in that the device further includes a regulating section that regulates rotation of the common attachment body attached to the one-side attachment portion in a direction opposite to the one direction, and a regulating section that regulates rotation of the common attachment body attached to the other-side attachment portion in a direction opposite to the one direction. Effect of the Invention

[0008] According to the present invention, a single examination table can be used to accommodate both right-handed and left-handed doctors. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. 1 and 2 are diagrams illustrating the examination table 1 according to this embodiment. Fig. 1 is a diagram of the examination table 1 as viewed from above, and Fig. 2 is a perspective view of the examination table 1 as viewed from the direction indicated by the arrow II in Fig. 1. The examination table 1 of this embodiment is a dental examination table 1, which supports from below a patient P (see FIG. 1) who is the subject of treatment and is lying on his / her back.

[0011] As shown in FIG. 1, an examination table 1 of this embodiment is provided with a support part 10 that supports a patient P lying on his / her back from below. The support section 10 is disposed so as to extend horizontally. The support section 10 is also disposed so as to extend in the height direction of the patient P in a supine position, and supports the entire body of the patient P from the head to the legs from below.

[0012] The support part 10 is provided with a flexible elastic member 11 at a portion that comes into contact with the patient P. In this embodiment, the elastic member 11 is provided over the entire upper surface of the support part 10. Furthermore, in this embodiment, a support body 12 (not shown in Figs. 1 and 2) (described later) is provided below this elastic member 11 to support this elastic member 11 from below.

[0013] 1, in this embodiment, a head support portion 10A is provided as a part of the support portion 10. This head support portion 10A supports the head of the patient P in a lying position from below. Furthermore, in this embodiment, as shown in Fig. 2, a lifting mechanism 20 for lifting and lowering the support part 10 is provided. Also, as shown in Figs. 1 and 2, a doctor's chair 21 on which the dentist sits and an assistant's chair 22 on which a medical assistant sits are provided around the examination table 1.

[0014] 1 and 2, the examination table 1 of this embodiment is provided with a table unit 100, which is an example of a common mounting body. In this embodiment, the table unit 100 supports various medical instruments and materials used in the examination from below. This table unit 100 is detachable from the support part 10 of the examination table 1. In this embodiment, the table unit 100 can be attached to a plurality of positions on the support part 10 (details will be described later).

[0015] Fig. 3 is a diagram showing the part indicated by reference symbol 1A in Fig. 1 as viewed from above in the direction of arrow III. Note that this figure shows a state in which the elastic member 11 has been removed. In this embodiment, a support body 12 is provided below the elastic member 11. This support body 12 is made of a metal frame. Furthermore, in this embodiment, the one-side mounted portion 41 is supported by the support portion main body 12. In this embodiment, the one-side mounted portion 41 has the table unit 100 mounted thereon.

[0016] More specifically, one mounted portion 41 is provided with an insertion portion 41A. The insertion portion 41A is configured as a hole having a rectangular cross section, and in this embodiment, a part of the table unit 100 is inserted into the insertion portion 41A. When a part of the table unit 100 is inserted into the insertion portion 41A, the table unit 100 is fixed to the one-side mounting portion 41.

[0017] In addition, although not shown in the figures, in this embodiment, a locking mechanism for maintaining the table unit 100 fixed to the one-side mounting portion 41, and a release mechanism for releasing the fixation maintained by this locking mechanism are provided. Here, the locking mechanism and the releasing mechanism may be an existing latch mechanism or the like, and are not limited to a specific mechanism. The locking mechanism and the releasing mechanism are also provided in the other-side mounting portion 42, which will be described later.

[0018] Fig. 4 is a diagram showing a part of the examination couch 1 as seen from above in the direction indicated by the arrow IV in Fig. 1. Note that this figure also shows a state in which the elastic member 11 has been removed. In this embodiment, an other-side mounting portion 42 is provided on the opposite side to the one-side mounting portion 41. In this embodiment, the table unit 100 (not shown in FIG. 4) can be mounted not only to the one-side mounting portion 41 but also to the other-side mounting portion 42. More specifically, the other-side mounting portion 42 also has an insertion portion 42A, and in this embodiment, the table unit 100 can be mounted to the other-side mounting portion 42 by inserting a part of the table unit 100 into this insertion portion 42A.

[0019] In the examination table 1 of this embodiment, a table unit 100, which is a common mounting body, can be mounted on each of the one-side mounting portion 41 and the other-side mounting portion . In other words, in this embodiment, the table unit 100 attached to one of the one-side attachment portion 41 and the other-side attachment portion 42 can be removed. In this embodiment, the detached table unit 100 can be attached to the other attachment portion.

[0020] Here, the one-side mounted portion 41 and the other-side mounted portion 42 each have the same configuration. That is, the one-side mounted portion 41 and the other-side mounted portion 42 each are provided with an insertion portion 41A (see FIG. 3) and an insertion portion 42A into which a part of the table unit 100 is inserted. In this embodiment, a part of the table unit 100 is inserted into the insertion portion 41A and the insertion portion 42A, and the common table unit 100 is fixed to the one-side mounted portion 41 and the other-side mounted portion 42.

[0021] 1 and 2 show a vertical plane 50 (a virtual vertical plane 50) that is a plane along the vertical direction. This vertical plane 50 passes through a center line C1 (see FIGS. 1 and 2) along the longitudinal direction of the support part 10, and as shown in FIG. 2, extends along the vertical direction. Here, the "center line C1" is a line passing through the center of the support part 10 in the short side direction (see FIG. 1) and along the longitudinal direction of the support part 10. Also, the "center line C1" is a line passing through the center of the support part 10 in the short side direction and can be said to be a line along the height direction of the patient P in a lying down position. In addition, when the support part 10 is formed in an asymmetric shape, a line passing through the center of the widest part of the support part 10 and extending along the longitudinal direction of the support part 10 is defined as the "center line C1".

[0022] 1, there are two regions 1X and 1Y that face each other across the vertical plane 50 that passes through the center line C1 of the support part 10. In this embodiment, one-side mounting part 41 is provided on the side of one region 1X of the two regions. In this embodiment, the other-side mounting portion 42 is provided on the other of the two regions, that is, the region 1Y.

[0023] In addition, in this embodiment, as shown in Figure 1, if a straight line L1 (a virtual straight line L1) is imagined as a straight line passing through the one-side mounted portion 41 and perpendicular to the vertical plane 50, the other-side mounted portion 42 is located on this straight line L1. In other words, in this embodiment, both the one-side mounted portion 41 and the other-side mounted portion 42 are located on one perpendicular line to the vertical plane 50.

[0024] In addition, in this embodiment, the distance D1 (measured along the straight line L1) between the one-side mounting portion 41 and the vertical surface 50 is equal to the distance D2 (measured along the straight line L1) between the other-side mounting portion 42 and the vertical surface 50. In other words, in this embodiment, the one-side mounted portion 41 and the other-side mounted portion 42 are arranged in a plane-symmetrical relationship with respect to the vertical plane 50.

[0025] Here, a typical dental treatment table 1 used in dental treatment is designed to accommodate right-handed dentists, and there is a demand for a treatment table 1 that is suitable for left-handed dentists. Here, assume that in order to accommodate left-handed dentists, a left-handed examination table 1 is prepared in addition to a right-handed examination table 1. In this case, it becomes necessary to prepare parts for the right-handed examination table 1 and parts for the left-handed examination table 1 separately, which increases the number of parts and requires time and effort for managing the parts. In contrast, in this embodiment, a single examination table 1 can be converted into an examination table 1 for right-handed and left-handed users simply by changing the table unit 100, which is a common attachment body, thereby reducing the effort required for managing parts, etc.

[0026] The treatment couch 1 will be further described with reference to FIG. In this embodiment, there are provided two sets of assistant tools 52 for use by a medical assistant. More specifically, one set of assistant tools 52A and the other set of assistant tools 52B are provided. In this embodiment, the medical instruments included in each set include an injection device 53 (three-way syringe) that injects water, air, and a mixture of water and air, and a suction instrument 54 used to suction saliva from the oral cavity of patient P. The spray device 53 and the suction tool 54 can be pulled out from the support body 12.

[0027] One set of assistant tools 52A is arranged on one area 1X side, and the other set of assistant tools 52B is arranged on the other area 1Y side. Here, in this embodiment, as shown in FIG. 1, when the table unit 100 is attached to the one-side attachment portion 41, the assistant assists in medical treatment using the other set of assistant's tools 52B arranged on the other side of the area 1Y. Also, although not shown in the figure, when the table unit 100 is attached to the other side mounting portion 42, the assistant assists in the medical treatment using one set of assistant tools 52A (see Figure 4) arranged on one side of the area 1X.

[0028] In this embodiment, some of the assistant's tools included in the assistant's tools 52A of one set and some of the assistant's tools included in the assistant's tools 52B of the other set are shared. Specifically, in the example shown in FIG. 4, the suction tool 54 is shared, and one suction tool 54 designated by reference symbol 4A is shared. When the assistant uses the other set of assistant's instruments 52B, the suction instrument 54 (suction instrument 54 indicated by reference symbol 4A) provided as a part of the assistant's instruments 52A of one set is removed and attached to the instrument attachment part 52X provided on the assistant's instruments 52B of the other set. More specifically, the plug 52Y attached to the tip of the instrument attachment part 52X is removed, and then the suction instrument 54 is attached to the instrument attachment part 52X.

[0029] The table unit 100 will now be described in detail. Fig. 5 is a diagram illustrating the table unit 100. Note that Fig. 5 shows the table unit 100 as viewed from below. In other words, Fig. 5 shows the table unit 100 as viewed from the back side. FIG. 5 shows the state of the table unit 100 when the table unit 100 is attached to the one-side mounting portion 41 (see FIG. 1).

[0030] The table unit 100 is provided with fixed parts 110 that are fixed to the one-side mounted part 41 and the other-side mounted part 42. More specifically, the table unit 100 is provided with fixed parts 110 that are inserted into the insertion parts 41A and 42A shown in Figures 3 and 4. The fixed parts 110 are made of a tubular member having a rectangular cross-sectional shape. Furthermore, the table unit 100 is provided with a moving part 120 that is movable relative to the fixed part 110 .

[0031] In this embodiment, the moving section 120 includes an object support stage 130 that supports an object from below, and a support member 150 that supports the object support stage 130. The object support table 130 is a so-called table, and supports various instruments and materials used in dental treatment. The support member 150 is configured of a tubular member having a rectangular cross-sectional shape. In this embodiment, the length of the support member 150 is greater than the length of the fixed portion 110.

[0032] In this embodiment, one end 151 of the support member 150 is fixed to the rear surface (lower surface) of the object support stage 130 , and the other end 152 of the support member 150 is fixed to the fixed portion 110 . One end 151 of the support member 150 is fixed to the radial center of the object support stage 130. The other end 152 of the support member 150 is fixed to an end of the fixed portion 110 (the end opposite to the end inserted into the insertion portion 41A (see FIG. 3)). In this embodiment, the fixed portion 110 is located outside the outer periphery 131 of the object support stage . The other end 152 of the support member 150 is located outside the outer periphery 131 of the object support stage .

[0033] In this embodiment, the support member 150 can rotate relative to the fixed portion 110, and the object support base 130 can rotate relative to the support member 150. More specifically, in this embodiment, the support member 150 is rotatable in the direction indicated by the arrow 5A around the connection point 121 between the fixed portion 110 and the support member 150 as the center of rotation. In this embodiment, the object support stage 130 is rotatable in the direction indicated by the arrow 5B around the connection point 122 between the support member 150 and the object support stage 130 as the center of rotation.

[0034] In this embodiment, when a horizontal load is applied to the object support base 130 of the table unit 100 fixed to the one-side mounting portion 41 or the other-side mounting portion 42, the support member 150 rotates about the connection point 121. This causes the object support base 130 to move. Furthermore, in this embodiment, when a horizontal load is applied to a part of the object support stage 130, the object support stage 130 rotates around the connection point 122. As a result, in this embodiment, the position of the object support base 130 relative to the support unit 10 (see FIG. 1) and the attitude of the object support base 130 relative to the support unit 10 can be changed.

[0035] Here, FIG. 5 shows the state of the table unit 100 when the table unit 100 is attached to the one-side mounting portion 41 (see FIG. 1). When the table unit 100 is attached to the one-side mounting portion 41, the support member 150 and the fixed portion 110 are disposed on the one end portion 132 side in the width direction of the object support table .

[0036] On the other hand, when the table unit 100 is attached to the other-side attachment part 42 (see FIG. 1), the support member 150 rotates relative to the object support base 130, and the fixed part 110 rotates relative to the support member 150, so that the support member 150 and the fixed part 110 are in the state shown by the dashed line 5X in FIG. 5. That is, the support member 150 and the fixed part 110 are disposed on the other end part 133 side in the width direction of the object support base 130. Then, the table unit 100, in which the support member 150 and the fixed portion 110 are in the state shown by the dashed line 5X, is fixed to the other-side mounted portion 42 (see FIG. 1).

[0037] As shown in FIG. 5, the table unit 100 of this embodiment is provided with an attachment member 200. In this embodiment, two mounting members 200, a first mounting member 210 and a second mounting member 250, are provided as the mounting members 200, and these two mounting members 200 are attached to the table unit 100. In this embodiment, the first attachment member 210 is located farther from the object support stage 130 than the second attachment member 250.

[0038] In this embodiment, in a state in which the table unit 100 is attached to the one-side attachment portion 41 and the other-side attachment portion 42, the first attachment member 210 is disposed below the second attachment member 250. The first attachment member 210 supports a first medical instrument (described later) from below. The second attachment member 250 supports a second medical instrument (described later) from below.

[0039] In this embodiment, the first attachment members 210 can be attached to the table unit 100 at a plurality of locations. More specifically, in this embodiment, the table unit 100 is provided with two attachment points, a first attachment point 91 and a second attachment point 92, and a first attachment member 210 can be attached to each of these two attachment points.

[0040] The first mounting member 210 is provided with a first mounting portion 211 and a second mounting portion 212, and the first mounting portion 211 is fixed to the first mounting location 91. The second mounting portion 212 is fixed to the second mounting location 92. More specifically, each of the first mounting portion 211 and the second mounting portion 212 has a through hole 94 (see Figure 6), and a screw 95 is passed through this through hole 94 and fixed to the first mounting location 91 or the second mounting location 92. As a result, the first attachment portion 211 is fixed to the first attachment location 91, and the second attachment portion 212 is fixed to the second attachment location 92.

[0041] The table unit 100 is provided with a first surface M1 and a second surface M2 that intersect with each other. In this embodiment, the first surface M1 serves as a first attachment location 91, and the second surface M2 serves as a second attachment location 92. Moreover, the table unit 100 of this embodiment is provided with a rod-shaped member 410 and a first fixing member 420 fixed to this rod-shaped member 410. In this embodiment, the first fixing member 420 is provided with a first surface M1 and a second surface M2. In this embodiment, the first surface M1 of the first fixing member 420 serves as a first attachment location 91, and the second surface M2 of the first fixing member 420 serves as a second attachment location 92.

[0042] The rod-shaped member 410 is attached to the lower surface 135 of the object support table 130 and extends in a direction away from the lower surface 135 . The first fixing member 420 is fixed to the tip end of the rod-shaped member 410 . Moreover, the first surface M1 and the second surface M2 provided on the first fixing member 420 are disposed so as to intersect with each other.

[0043] In addition, a second fixing member 430 is fixed to the rod-shaped member 410. This second fixing member 430 is located closer to the object support stage 130 than the first fixing member 420. In this embodiment, the second mounting member 250 is attached to the second fixing member 430.

[0044] In this embodiment, when the first mounting member 210 is changed from a state in which it is attached to the second mounting location 92 (second surface M2) to a state in which it is attached to the first mounting location 91 (first surface M1), the angle (posture) of the first mounting member 210 changes.

[0045] Here, the posture of the first attachment member 210 with respect to the table unit 100 when the first attachment member 210 is attached to the first attachment location 91 is referred to as a first posture. Moreover, the posture of the first attachment member 210 with respect to the table unit 100 when the first attachment member 210 is attached to the second attachment point 92 is referred to as a second posture. In this embodiment, the first attitude and the second attitude are different. In other words, in this embodiment, the attitude of the first attachment member 210 with respect to the table unit 100 changes depending on the attachment location of the first attachment member 210.

[0046] Fig. 6 is a diagram showing a state in which the table unit 100 is fixed to the other-side mounting portion 42. Note that Fig. 6 also shows a first medical instrument K1 supported by the first mounting member 210 and a second medical instrument K2 supported by the second mounting member 250. Here, the first medical instrument K1 and the second medical instrument K2 are so-called hand pieces, and are used when grinding the patient P's teeth.

[0047] A first pipe T1 is connected to the first medical instrument K1, and a second pipe T2 is connected to the second medical instrument K2. In this embodiment, electricity, water, compressed air, etc. are supplied to the first medical instrument K1 and the second medical instrument K2 through the first pipe T1 and the second pipe T2. In this embodiment, the supplied electricity and compressed air rotate the rotating bodies located inside the first medical instrument K1 and the second medical instrument K2, thereby rotating the cutting tools (drills) provided at the tips of the first medical instrument K1 and the second medical instrument K2.

[0048] When the table unit 100 is fixed to the other-side mounting portion 42, the first mounting member 210 is fixed to the first mounting portion 91 of the first fixing member 420, as shown in FIG. When the table unit 100 is fixed to the other-side mounting portion 42, the mounting member 200 (first mounting member 210, second mounting member 250) faces the dentist (not shown in FIG. 6) (see FIG. 1). In this embodiment, even when the table unit 100 is fixed to the one-side mounting portion 41 (see FIG. 1), the mounting members 200 (the first mounting member 210 and the second mounting member 250) face the dentist side.

[0049] As in this embodiment, when each part of the table unit 100 is capable of rotating, the mounting member 200 (first mounting member 210, second mounting member 250) can be faced toward the dentist regardless of whether the table unit 100 is attached to the one-side mounting portion 41 or the other-side mounting portion 42. In other words, since each part of the table unit 100 can be rotated, the first medical instrument K1 and the second medical instrument K2 can be directed toward the dentist regardless of whether the table unit 100 is attached to the one-side mounting part 41 or the other-side mounting part 42.

[0050] Here, in this embodiment, as shown in FIG. 6, a groove 10M extending along the width direction of the object support base 130 is formed in the first mounting member 210, and in this embodiment, a cylindrical first medical instrument K1 is housed in this groove 10M. The second attachment member 250 also has a groove 20M formed therein, which extends along the width direction of the object support base 130, and a cylindrical second medical instrument K2 is housed within this groove 20M.

[0051] FIG. 6 shows a state in which the first mounting portion 211 of the first mounting member 210 is mounted to the first mounting location 91 of the first fixing member 420. In this embodiment, when attaching the table unit 100 to the other-side mounting portion 42, the first mounting portion 211 of the first mounting member 210 is attached to the first mounting location 91 in this manner.

[0052] In this embodiment, when attaching the table unit 100 to the one-side mounting portion 41 (see FIG. 1), the second mounting portion 212 of the first mounting member 210 is attached to the second mounting location 92 shown in FIG. In the case where the table unit 100 is provided with two attachment points, the first attachment point 91 and the second attachment point 92, as in this embodiment, the attitude of the first attachment member 210 relative to the object support base 130 can be made to differ.

[0053] In this embodiment, the location where the first attachment member 210 (see FIG. 6) is provided can be regarded as a first support portion 71 that supports the first medical instrument K1. Moreover, the location where the second mounting member 250 is provided can be regarded as a second support portion 72 that supports the second medical instrument K2. In this embodiment, the first support portion 71 and the second support portion 72 are provided so that the first medical instrument K1 supported by the first support portion 71 and the second medical instrument K2 supported by the second support portion 72 are not parallel to each other.

[0054] In this embodiment, when the table unit 100 shown in Figure 6 is viewed from above, the second medical instrument K2 is arranged along the straight portion indicated by symbol 6A of the outer peripheral edge 131 of the object support base 130 (hereinafter referred to as the "straight portion 131E"). In contrast, the first medical instrument K1 is arranged not along the straight portion 131E but at an angle to the straight portion 131E.

[0055] More specifically, in this embodiment, the first surface M1 (first attachment point 91) and the second surface M2 (second attachment point 92) do not extend along the straight portion 131E, but are inclined relative to the straight portion 131E. For this reason, when the first attachment member 210 is attached to the first surface M1 or the second surface M2, the first attachment member 210 is inclined with respect to the linear portion 131E. Accordingly, the first medical instrument K1 is also not aligned along the linear portion 131E but is inclined with respect to the linear portion 131E.

[0056] On the other hand, in this embodiment, the second attachment member 250 is not inclined with respect to the linear portion 131E. Accordingly, the second medical instrument K2 is aligned along the linear portion 131E. In this case, the first medical instrument K1 supported by the first support portion 71 (see FIG. 6) and the second medical instrument K2 supported by the second support portion 72 are not parallel to each other.

[0057] FIG. 6 shows a state in which the first mounting portion 211 of the first mounting member 210 is mounted to the first surface M1 of the first fixing member 420, as described above. In contrast, when the second mounting portion 212 of the first mounting member 210 is attached to the second surface M2, the first mounting member 210 and the first medical instrument K1 are arranged so as to be aligned along the direction indicated by the dashed line 6Y.

[0058] More specifically, in this embodiment, when the table unit 100 is attached to the one-side mounting portion 41 (see FIG. 1), the second mounting portion 212 of the first mounting member 210 is attached to the second surface M2 shown in FIG. In this case, the first attachment member 210 and the first medical instrument K1 are arranged along the direction indicated by the dashed line 6Y.

[0059] In other words, when the table unit 100 is attached to the one-side attachment portion 41, the attitude of the first attachment member 210 relative to the table unit 100 is changed. In this case, the first attachment member 210 and the first medical instrument K1 are arranged along the direction indicated by the dashed line 6Y in FIG.

[0060] In this embodiment, even in this case (when the second mounting portion 212 is attached to the second surface M2), the first medical instrument K1 supported by the first support portion 71 and the second medical instrument K2 supported by the second support portion 72 are not parallel to each other. In addition, in this case as well, the first medical instrument K1 does not extend along the straight portion 131E, but forms an angle with respect to the straight portion 131E. In other words, in this embodiment, the attachment point of the first mounting member 210 is changed from the first surface M1 to the second surface M2, and even if the posture of the first support part 71 is changed, the first medical instrument K1 and the second medical instrument K2 will not be parallel to each other.

[0061] Here, when the first medical instrument K1 supported by the first support part 71 (see FIG. 6) and the second medical instrument K2 supported by the second support part 72 are parallel to each other, the first pipe T1 connected to the first medical instrument K1 and the second pipe T2 connected to the second medical instrument K2 are likely to come into contact with each other. More specifically, when the first medical instrument K1 and the second medical instrument K2 are parallel, the second pipe T2 connected to the second medical instrument K2 is likely to be positioned on the extension line 6X of the first medical instrument K1, and the first pipe T1 and the second pipe T2 are likely to come into contact with each other.

[0062] In this case, when a dentist picks up either the first medical instrument K1 or the second medical instrument K2, the movement of the piping connected to the one medical instrument tends to cause the piping connected to the other medical instrument to move. In this case, the other medical instrument may move and become easily dropped off.

[0063] In contrast, in the present embodiment, in which the first medical instrument K1 supported by the first support portion 71 and the second medical instrument K2 supported by the second support portion 72 are not parallel, the pipes are less likely to come into contact with each other. In this case, when one medical instrument is removed, the other medical instrument is less likely to fall off or otherwise become out of place.

[0064] Here, when the state shown in Figure 6 (where the table unit 100 is attached to the other-side mounting portion 42) is changed to a state where the table unit 100 is attached to the one-side mounting portion 41 (see Figure 1), the orientations of the first medical instrument K1 and the second medical instrument K2 are also changed. More specifically, when the table unit 100 is attached to the one-side mounting portion 41, as described above, the first mounting member 210 is attached to the second surface M2 of the first fixing member 420 (see Figure 6), and in addition to this, the orientations of the first medical instrument K1 and the second medical instrument K2 are also changed.

[0065] FIG. 7 is a diagram showing a state in which the table unit 100 is attached to the one-side mounting portion 41 (see FIG. 1). As shown in Figure 7, when the table unit 100 is attached to the one-side attachment portion 41, the first medical instrument K1 and the second medical instrument K2 are positioned so that the tip of the first medical instrument K1 and the tip of the second medical instrument K2 face in the directions indicated by arrows 7A and 7B. More specifically, the first medical instrument K1 and the second medical instrument K2 are positioned so that the tip of the first medical instrument K1 and the tip of the second medical instrument K2 face the one end 132 side in the width direction of the object support stand 130.

[0066] In this embodiment, the attitude of the first attachment member 210 relative to the table unit 100 can be changed as described above. In this embodiment, the attitude of the first support portion 71 with respect to the table unit 100 is changed in response to a change in the attitude of the first attachment member 210. Furthermore, in this embodiment, the attitude of the first support portion 71 relative to the second support portion 72 is changed in response to a change in the attitude of the first attachment member 210.

[0067] In this embodiment, a case has been described in which the attitude of the first support part 71 relative to the second support part 72 is changed by changing the attitude of the first mounting member 210, but the attitude of the first support part 71 relative to the second support part 72 may be changed by other methods. For example, the attachment location of the second attachment member 250 may be made changeable, and the attachment location of the second attachment member 250 may be varied to change the posture of the second attachment member 250, thereby changing the posture of the first support portion 71 relative to the second support portion 72.

[0068] 8(A) and (B) are diagrams illustrating the first attachment member 210. Fig. 8(A) is a perspective view of the first attachment member 210 when viewed from above, and Fig. 8(B) is a front view of the first attachment member 210. As shown in FIG. 8(A), the first mounting member 210 has a fixing portion 210A formed in a plate shape and fixed to the first fixing member 420 (see FIG. 5), and an opposing portion 210B also formed in a plate shape and arranged at a position opposite the fixing portion 210A.

[0069] Furthermore, as shown in FIG. 8(A), the first attachment member 210 includes a connection portion 210C that is formed so as to be convex downward and that connects the lower end of the fixing portion 210A and the lower end of the facing portion 210B. Moreover, first attachment member 210 is formed so as to extend in the direction indicated by arrow 8A in the figure, and has one end 210E and another end 210F that are located at different positions in the direction indicated by arrow 8A.

[0070] As shown in FIG. 8(A), a through hole 94 is provided in the fixing portion 210A. In this embodiment, the through holes 94 include a first through hole 210G and a second through hole 210H. The first through hole 210G is located on one end 210E side of the first mounting member 210. The second through hole 210H is located on the other end 210F side of the first mounting member 210.

[0071] In this embodiment, screws 95 (see FIG. 6) for fixing the first mounting member 210 to the first fixing member 420 (see FIG. 5) are passed through the first through holes 210G and the second through holes 210H. In this embodiment, the first attachment portion 211 (see FIG. 5) described above is a portion of the fixed portion 210A (see FIG. 8) where the first through hole 210G is provided, and the second attachment portion 212 (see FIG. 5) is a portion of the fixed portion 210A (see FIG. 8) where the second through hole 210H is provided.

[0072] In this embodiment, as shown in FIG. 8(A), a groove 10M is formed in a region surrounded by the fixed portion 210A, the facing portion 210B, and the connecting portion 210C along the direction indicated by the arrow 8A in the figure. In this embodiment, the first medical instrument K1 (see FIGS. 6 and 7) is placed along this groove 10M. As shown in FIG. 8(A), a first protrusion T11 and a second protrusion T12 are provided on the upper surface of the connection portion 210C.

[0073] On the other hand, the first medical instrument K1 is provided with a cylindrical instrument body 500 and a cylindrical attachment part 510 to which the instrument body 500 is attached, as shown in FIG. In this embodiment, the tool body 500 can be attached to and detached from the attachment portion 510. In this embodiment, when comparing the outer diameter of the base side of the instrument main body 500 (the outer diameter of the part located on the mounting portion 510 side) with the outer diameter of the mounting portion 510, the outer diameter of the instrument main body 500 is larger than the outer diameter of the mounting portion 510.

[0074] Here, in this embodiment, as shown in FIG. 6, when the tip of the first medical instrument K1 is positioned facing the other end 133 of the object support stand 130, the first medical instrument K1 is positioned in the state shown in (A) of FIG. 9 (a diagram showing the state of the first medical instrument K1 and the first mounting member 210 when viewed from above). When the tip of the first medical instrument K1 is positioned facing the other end 133 of the object support base 130, as shown in FIG. 9(A), the instrument main body 500 gets caught on the first protrusion T11, restricting movement of the first medical instrument K1 to the left in the figure.

[0075] Also, as shown in Figure 7, when the first medical instrument K1 is positioned with the tip of the first medical instrument K1 facing one end 132 of the object support stand 130, the first medical instrument K1 is positioned in the state shown in Figure 9 (B). In the state shown in FIG. 9(B), the instrument main body 500 is caught by the second protrusion T12, and the movement of the first medical instrument K1 to the right in the figure is restricted.

[0076] Fig. 10 is a view of the support part 10 viewed from below and from the side where the head support part 10A is provided. More specifically, Fig. 10 shows the state of the lower surface 10X of the support part 10 when the table unit 100 is attached to the one-side mounting part 41 (see Fig. 1(A)). In this embodiment, as another example of a common mounting body, a pipe support member 600 is provided as shown in Fig. 10. The pipe support member 600 is attached to the lower surface 10X of the support portion 10.

[0077] In this embodiment, the first pipe T1 extends from the lower surface 10X of the support part 10 toward the first medical instrument K1 (not shown in FIG. 10). The second pipe T2 also extends from the lower surface 10X of the support part 10 toward the second medical instrument K2. The pipe support member 600 supports the first pipe T1 and the second pipe T2. The first pipe T1 has a tip connected to a first medical instrument K1, and the second pipe T2 has a tip connected to a second medical instrument K2.

[0078] The first pipe T1 and the second pipe T2 extend from the central portion C2 of the support part 10 on the underside 10X of the support part 10 toward the medical instruments (the first medical instrument K1 and the second medical instrument K2). More specifically, the first pipe T1 and the second pipe T2 start from a central portion C2 in the short direction of the support part 10 (a direction perpendicular to the longitudinal direction of the support part 10) and head toward the medical instrument.

[0079] In this way, when the starting point of the piping is located in the central part C2 in the short side direction of the support part 10, it is easier to arrange the first piping T1 and the second piping T2 from the support part 10 to the table unit 100 than when the starting point is located on either the one side of the region 1X or the other side of the region 1Y.

[0080] When the starting point of the piping is located at the central part C2 in the short direction of the support part 10, the distance from this starting point to the table unit 100 attached to the one-side mounting part 41 is equal to the distance from this starting point to the table unit 100 attached to the other-side mounting part 42. In this case, regardless of whether the table unit 100 is attached to the one-side mounting part 41 or the other-side mounting part 42, it becomes easier to arrange the first piping T1 and the second piping T2 from the support part 10 to the table unit 100.

[0081] In this embodiment, similarly to the table unit 100, the pipe support member 600 can be attached to two locations, that is, the one-side attached portion 81 and the other-side attached portion . Specifically, in this embodiment, the portion indicated by the symbol 10A in Figure 10 is one-side mounting portion 81 to which the piping support member 600 is attached, and the portion indicated by the symbol 10B is the other-side mounting portion 82 to which the piping support member 600 is attached.

[0082] In this embodiment, similarly to the above, the one-side mounted portion 81 is located on the one area 1X side, and the other-side mounted portion 82 is located on the other area 1Y side. Furthermore, in this embodiment, similarly to the above, the other-side mounted portion 82 is located on the straight line L2 that passes through the one-side mounted portion 81 and is perpendicular to the vertical plane 50 (see FIG. 1). In addition, the distance D3 (measured along the straight line L2) between the one side mounted portion 81 and the vertical surface 50 is equal to the distance D4 (measured along the straight line L2) between the other side mounted portion 82 and the vertical surface 50.

[0083] FIG. 11 is a diagram illustrating the pipe support member 600. As shown in FIG. The pipe support member 600 is provided with a cylindrical first pipe support portion 610 through which the first pipe T1 (see FIG. 10) passes and which supports the first pipe T1. The pipe support member 600 is also provided with a cylindrical second pipe support portion 620 through which the second pipe T2 (see FIG. 10) passes and which supports the second pipe T2. Furthermore, in this embodiment, a first plate-shaped portion 631 to a fourth plate-shaped portion 634 each formed in a plate shape are provided.

[0084] The first plate-shaped portion 631 and the second plate-shaped portion 632 have one end connected to the outer circumferential surface of the first pipe support portion 610 and are provided so as to protrude in one direction indicated by the arrow 11A in the figure. Here, the first plate-shaped portion 631 and the second plate-shaped portion 632 are arranged in a parallel relationship to each other. The third plate-shaped portion 633 and the fourth plate-shaped portion 634 have one end connected to the outer circumferential surface of the second piping support portion 620 and are provided so as to protrude in one direction indicated by the arrow 11B in the figure. In other words, the third plate-shaped portion 633 and the fourth plate-shaped portion 634 protrude in the opposite direction to the protruding direction of the first plate-shaped portion 631 and the second plate-shaped portion 632. The third plate-shaped portion 633 and the fourth plate-shaped portion 634 are disposed in parallel to each other.

[0085] The pipe support member 600 is provided with a first fixed portion 650 that is fixed to the one-side mounting portion 81 (see FIG. 10). The pipe support member 600 is also provided with a second fixed portion 660 that is provided at a location different from the first fixed portion 650 and is fixed to the other-side mounted portion 82 (see FIG. 10).

[0086] The pipe support member 600 is formed in a flat shape, and has at least two surfaces: a first surface 671 and a second surface 672 disposed on the opposite side to the first surface 671. In this embodiment, a first fixed portion 650 is provided on a first surface 671 side, which is one of the two surfaces, and a second fixed portion 660 is provided on a second surface 672 side, which is the other surface. Here, the "first surface 671 side" refers to the portion of the pipe support member 600 formed in a flat shape that is located closer to the first surface 671 than the central portion CH in the thickness direction, and the "second surface 672 side" refers to the portion of the pipe support member 600 that is located closer to the second surface 672 than the central portion CH in the thickness direction.

[0087] In this embodiment, a first groove 651 and a second groove 652 are provided in a first fixed portion 650 provided on the first surface 671 side. More specifically, in this embodiment, the first groove 651 is formed in the first plate-shaped portion 631, and the second groove 652 is formed in the third plate-shaped portion 633. In this embodiment, a third groove 661 and a fourth groove 662 are provided in the second fixed portion 660 provided on the second surface 672. More specifically, in this embodiment, the third groove 661 is formed in the second plate-shaped portion 632, and the fourth groove 662 is formed in the fourth plate-shaped portion 634.

[0088] On the other hand, in this embodiment, the one-side mounting portion 81 (see FIG. 10) has a protrusion 690 protruding downward in the vertical direction on the underside 10X of the support portion 10, as shown in FIG. 12 (a diagram showing the state of the underside 10X of the support portion 10). The protrusions 690 are positioned at locations corresponding to the first groove 651 (see FIG. 11) and the second groove 652 of the tube support member 600. Additionally, two of the protrusions 690 are provided on the one-side mounting portion 81 (see FIG. 10). Each of the protrusions 690 is located at a position where the first groove 651 and the second groove 652 are disposed when the pipe support member 600 is attached to the one-side mounting portion 81.

[0089] Moreover, two of these projections 690 are provided on the other-side mounting portion 82 (see FIG. 10) (the projections 690 are not shown in FIG. 10). The protrusions 690 provided on the other-side mounting portion 82 are positioned at locations where the third groove 661 (see FIG. 11) and the fourth groove 662 are located when the pipe support member 600 is attached to the other-side mounting portion 82.

[0090] 12, the protrusion 690 is provided with a rod-shaped portion 691 extending vertically downward from the lower surface 10X of the support portion 10, and a large diameter portion 692 provided at the tip of the rod-shaped portion 691. In this embodiment, the outer diameter of the large diameter portion 692 is larger than the outer diameter of the rod-shaped portion 691. Furthermore, in this embodiment, the outer diameter of the rod-shaped portion 691 is smaller than the groove width of each of the first groove 651 (see FIG. 11) to the fourth groove 662, and the outer diameter of the large diameter portion 692 is larger than the groove width of each of the first groove 651 to the fourth groove 662.

[0091] In this embodiment, when the pipe support member 600 is attached to the one-side mounting portion 81 (see Figure 10), the portion where the first groove 651 (see Figure 11) is provided relative to one protrusion 690 is fixed, and the portion where the second groove 652 is provided relative to the other protrusion 690 is fixed. More specifically, when the pipe support member 600 is attached to the one-side mounting portion 81, the rod-shaped portion 691 of one protrusion 690 is inserted into the first groove 651, and the rod-shaped portion 691 of the other protrusion 690 is inserted into the second groove 652.

[0092] At this time, in this embodiment, the first plate-shaped portion 631 is positioned between the outer periphery 692A of the large diameter portion 692 of one of the projections 690 (see FIG. 12) and the lower surface 10X of the support portion 10. Moreover, the third plate-shaped portion 633 is positioned between the outer periphery 692A of the large diameter portion 692 of the other projection 690 and the lower surface 10X of the support portion 10.

[0093] As a result, the movement of the pipe support member 600 that tends to move downward due to the influence of gravity is restricted, and the pipe support member 600 is fixed to the one-side mounted portion 81. In a state in which the tube support member 600 is fixed to the one-side mounting portion 81, as shown in FIG. 10, the second tube support portion 620 is located on the head support portion 10A side.

[0094] Furthermore, when the piping support member 600 is attached to the other side mounting portion 82 (see Figure 10), the portion where the third groove 661 (see Figure 11) is provided is fixed to one protrusion 690, and the portion where the fourth groove 662 is provided is fixed to the other protrusion 690. More specifically, when the pipe support member 600 is attached to the other-side mounting portion 82, the rod-shaped portion 691 (see Figure 12) of one protrusion 690 is inserted into the third groove 661, and the rod-shaped portion 691 (see Figure 12) of the other protrusion 690 is inserted into the fourth groove 662 (see Figure 11).

[0095] At this time, in this embodiment, similarly to the above, the second plate-shaped portion 632 (see FIG. 11) is positioned between the outer periphery 692A of the large diameter portion 692 of one of the protrusions 690 and the lower surface 10X of the support part 10. Also, the fourth plate-shaped portion 634 is positioned between the outer periphery 692A of the large diameter portion 692 of the other protrusion 690 and the lower surface 10X of the support part 10. As a result, in this case as well, the movement of the pipe support member 600 attempting to move downward due to the influence of gravity is restricted, and the pipe support member 600 is fixed to the other-side mounted portion 82 .

[0096] FIG. 13 is a diagram showing a state in which the tube support member 600 is fixed to the other-side mounting portion 82. As shown in FIG. As shown in FIG. 13, in this embodiment, even in a state in which the tube support member 600 is fixed to the other-side mounting portion 82, the second tube support portion 620 is located on the head support portion 10A side. In this embodiment, as shown in FIG. 11, a second fixed portion 660 is provided on the surface opposite to the surface on which the first fixed portion 650 is provided.

[0097] Therefore, in this embodiment, when the pipe support member 600 fixed to the one-side mounted portion 81 is to be fixed to the other-side mounted portion 82, the pipe support member 600 is turned over. As a result, in this embodiment, even when the tube support member 600 is fixed to the other-side mounting portion 82, the second tube support portion 620 can be positioned on the head support portion 10A side.

[0098] Here, a mode may also be considered in which the second fixed portion 660 is not provided, and the pipe support member 600 is fixed to the other-side mounted portion 82 using the first fixed portion 650. That is, it is also possible to fix the pipe support member 600 to the other-side mounted portion 82 after only changing the orientation of the pipe support member 600 without turning the pipe support member 600 over. In this case, however, the first pipe support portion 610 ends up being located on the head support portion 10A side.

[0099] In this case (when the first pipe support part 610 is located on the head support part 10A side), the arrangement of the pipes (first pipe T1, second pipe T2) becomes asymmetric between the case where the pipe support member 600 is fixed to the one-side mounted part 81 and the case where the pipe support member 600 is fixed to the other-side mounted part 82. More specifically, the arrangement of the pipes becomes asymmetric when the vertical plane 50 (see FIG. 1) is the target plane. If the piping arrangement is asymmetrical, additional measures may be required to arrange the piping asymmetrically, which can easily result in a complex structure.

[0100] In contrast, in the configuration of this embodiment, the arrangement of the piping (first piping T1, second piping T2) when the piping support member 600 is fixed to the one-side mounting portion 81 is symmetrical to the arrangement of the piping when the piping support member 600 is fixed to the other-side mounting portion 82. In this case, the complexity of the structure caused by asymmetrically arranging the pipes is suppressed.

[0101] FIG. 16 is a diagram illustrating another configuration example of the pipe support member 600. In FIG. Figures 17(A) and (B) are diagrams for explaining the mounting protrusion 680 used for mounting the piping support member 600. Specifically, Figure 17(A) is a diagram of the mounting protrusion 680 viewed from the direction indicated by the arrow XVIIA in Figure 16, and Figure 17(B) is a diagram of the mounting protrusion 680 viewed from the direction indicated by the arrow XVIIB in Figure 17(A).

[0102] FIG. 18 is a cross-sectional view of the support portion 10 taken along line XVIII-XVIII in FIG. 16 shows the support part 10 as viewed from below. Also, in Fig. 16, the pipe support member 600 is shown fixed to the one-side mounting part 81. Also, in Fig. 16, the pipes (first pipe T1 and second pipe T2) are not shown.

[0103] In this embodiment, as indicated by reference numeral 16A in FIG. 16, the lower surface 10A of the support part 10 and the other-side mounted part 82 are provided with an attachment protrusion 680 that protrudes downward from the lower surface 10A. 17(A) and (B), the mounting projection 680 is provided with a cylindrical projection 681 that projects in a direction away from the lower surface 10A (vertically downward). The mounting projection 680 is also provided with a first projection 682A and a second projection 682B that project from the outer circumferential surface of the projection 681.

[0104] 16, the first protrusion 682A and the second protrusion 682B are disposed in a state shifted from each other by 180° in the circumferential direction of the cylindrical protrusion 681. In other words, in this embodiment, the second protrusion 682B is provided on the opposite side to the first protrusion 682A with the protrusion 681 in between. In this embodiment, as shown in FIG. 17, a gap G is provided between the first protrusion 682A, the second protrusion 682B, and the lower surface 10A.

[0105] 16C, a restricting portion 684 is provided to restrict rotation of the pipe support member 600. The restricting portion 684 has a cylindrical shape and protrudes downward from the lower surface 10A. As shown in FIG. 18, the restricting portion 684 is biased downward by a coil spring 685, which is an example of a biasing member, and protrudes from the lower surface 10A. In this configuration example, when the restricting portion 684 is pressed upward, the restricting portion 684 retreats. As shown in FIG. 16, the mounting projection 680 and the restricting portion 684 are provided not only on the other-side mounted portion 82 but also on the one-side mounted portion 81 .

[0106] The pipe support member 600 (see FIG. 16) is formed in a flat shape as described above, and has a first surface 671 (not shown in FIG. 16) facing the one-side mounted portion 81. The pipe support member 600 also has a second surface 672 facing the other-side mounted portion 82. Furthermore, in this embodiment, each of the first surface 671 and the second surface 672 is provided with a circular through hole 686.

[0107] Furthermore, each of the first surface 671 and the second surface 672 is provided with two grooves 687, a first groove 687A and a second groove 687B, which extend from the outer periphery of the through hole 686 toward the outside in the radial direction of the through hole 686. The first groove 687A and the second groove 687B are connected to the through hole 686. In this embodiment, one groove 687 is provided on the opposite side to one groove 687 with the through hole 686 interposed therebetween.

[0108] Furthermore, each of the first surface 671 and the second surface 672 is provided with a restriction through hole 688 into which the restriction portion 684 fits. Similarly to the above, the pipe support member 600 is provided with a first pipe support portion 610 that supports the first pipe T1 and a second pipe support portion 620 that supports the second pipe T2.

[0109] FIG. 19 is a perspective view of the tube support member 600 as viewed from the second surface 672 side. In this configuration example, as described above, the circular through hole 686 is provided on the second surface 672 side of the pipe support member 600. Also, on the second surface 672 side, the first groove 687A and the second groove 687B extending from the through hole 686 toward the outside in the radial direction of the through hole 686 are provided. Furthermore, a restriction through hole 688 is provided on the second surface 672 side of the pipe support member 600.

[0110] In this configuration example, a pipe support member 600 is configured by combining a flat first member 710 and a flat second member 720. In this configuration example, a gap is provided between the first member 710 and the second member 720, and a cavity is provided inside the tube support member 600. In this configuration example, first protrusion 682A and second protrusion 682B provided on mounting protrusion 680 (see FIG. 16) fit into this gap (cavity) (details will be described later).

[0111] FIG. 20 is a perspective view of the tube support member 600 as viewed from the first surface 671 side. The first member 710 is also provided with a through hole 686 . The first member 710 is also provided with a first groove 687A and a second groove 687B extending from the through hole 686 toward the outside in the radial direction of the through hole 686. Furthermore, the first member 710 is also provided with a restriction through hole 688 .

[0112] Fig. 21 is a diagram of the first member 710 as viewed from the direction indicated by the arrow XXI in Fig. 19. In other words, Fig. 21 is a diagram showing the inner surface 710A of the first member 710. As described above, the first member 710 has the circular through hole 686 formed therein, and further has two grooves 687 (first groove 687A, second groove 687B) extending from this through hole 686. Furthermore, the inner surface 710A of the first member 710 is provided with two rotation restricting projections 711 that project in a direction away from the inner surface 710A. Furthermore, an edge protrusion 713 that protrudes in a direction away from the inner surface 710A is also provided on an edge 712 located to the side of the first groove 687A and the second groove 687B of the inner surface 710A.

[0113] Figures 22(A) and (B) are diagrams for explaining the attachment of the pipe support member 600 to the one-side attachment portion 81 (see Figure 16). Note that Figures 22(A) and (B) show only the first member 710 among the members constituting the pipe support member 600. Also, Figures 22(A) and (B) show the state when the first member 710 is viewed from below in the vertical direction. In this embodiment, when the piping support member 600 is attached to the one-side mounting portion 81, first, the piping support member 600 is positioned so that the mounting protrusion 680 and the first member 710 are in the state shown in Figure 22 (A).

[0114] In other words, when the piping support member 600 is attached to the one-side mounting portion 81 (see Figure 16), the piping support member 600 is positioned so that the first surface 671 (see Figure 20) faces the one-side mounting portion 81 (see Figure 16) and so that the first protrusion 682A and the second protrusion 682B are positioned at opposing positions to the first groove 687A and the second groove 687B.

[0115] Next, the pipe support member 600 (see FIG. 22(A)) is pushed out toward the mounting projection 680. In other words, the pipe support member 600 is pushed out toward the one-side mounted portion 81 (see FIG. 16). As a result, the protruding portion 681 (see FIG. 22(A)) enters the through-hole 686, and the first projection 682A and the second projection 682B enter the tube support member 600 through the first groove 687A and the second groove 687B. Furthermore, at this time, the restricting portion 684 provided on the support portion 10 side is pressed by the first member 710 and retreats.

[0116] Thereafter, the tube support member 600 is rotated so that the first member 710 rotates in one direction indicated by an arrow 22A in FIG. 22(A). In this configuration example, the pipe support member 600 is rotated in one direction with the first surface 671 (see Figure 20), which is one surface of the pipe support member 600, facing the one-side mounting portion 81 (see Figure 16) and with the first protrusion 682A and the second protrusion 682B within the pipe support member 600.

[0117] As a result, the first protrusion 682A and the second protrusion 682B are positioned at opposing positions on the inner surface 710A of the first member 710, as shown in FIG. 22(B). More specifically, the first protrusion 682A and the second protrusion 682B are located at opposing positions in a portion of the inner surface 710A that is located around the through-hole 686. This allows the piping support member 600 to be caught by the mounting protrusions 680, preventing the piping support member 600 from coming off the lower surface 10A (see FIG. 16 ) of the support portion 10. In other words, the piping support member 600 is attached to the one-side attachment portion 81.

[0118] In this configuration example, when the piping support member 600 is rotated beyond a predetermined rotation angle, the first protrusion 682A (see Figure 22 (B)) and the second protrusion 682B come into contact with the rotation restricting protrusion 711, and the rotation of the piping support member 600 is restricted. Furthermore, in this configuration example, when the piping support member 600 is rotated, the first protrusion 682A and the second protrusion 682B climb over the edge protrusion 713 (see FIG. 22(B)) provided on the first member 710. When the first protrusion 682A and the second protrusion 682B climb over the edge protrusion 713, the operating load required to rotate the piping support member 600 decreases. This allows the operator installing the piping support member 600 to recognize that installation of the piping support member 600 is complete. It should be noted that the edge protrusion 713 is not essential. FIG. 25 is a cross-sectional view of the first member 710 taken along the line XXV-XXV in FIG. 22(B), showing a cross-sectional view of a configuration example in which the edge protrusion 713 is not provided. In this configuration example, the edge protrusion 713 is not provided. In addition, in this configuration example, the portion of inner surface 710A indicated by the symbol 25X approaches outer surface 710E of first member 710 as it approaches first groove 687A, and inner surface 710A is given a slope such that it approaches outer surface 710E as it approaches first groove 687A. In this configuration example, when the attachment of the tube support member 600 is completed, the portion of the first member 710 indicated by reference symbol 25Y is sandwiched between the first protrusion 682A and the lower surface 10A (see FIG. 16). In this embodiment, as described above, the inner surface 710A is inclined, and the operation load is small in the initial stage of attachment of the pipe support member 600, and increases as attachment of the pipe support member 600 progresses.

[0119] The explanation will be continued with reference to FIG. In this configuration example, when the pipe support member 600 is rotated, the restricting portion 684 is positioned at a position facing the restricting through hole 688 (see FIG. 22(B)), and the restricting portion 684 enters into the restricting through hole 688. When the restricting portion 684 enters the restricting through hole 688, the restricting portion 684 restricts the rotation of the pipe support member 600 in the direction opposite to the one direction (the rotation direction when the pipe support member 600 is attached). In other words, the rotation of the pipe support member 600 in the rotation direction of the pipe support member 600 when the pipe support member 600 is removed is restricted.

[0120] Next, the removal of the pipe support member 600 from the one-side mounting portion 81 will be described. When removing the piping support member 600 from the one-side mounting portion 81, first, the regulating portion 684 (see Figure 22(B)) provided on the one-side mounting portion 81 is pressed toward the underside 10A of the support portion 10 (see Figure 16) to move the regulating portion 684 away from the movement path of the piping support member 600. In other words, the restricting portion 684 is moved to the outside of the restricting through hole 688 (see FIG. 22(B)) provided in the first member 710.

[0121] Thereafter, the pipe support member 600 shown in FIG. 22(B) is rotated counterclockwise in the figure. As a result, first groove 687A and second groove 687B provided in first member 710 are positioned at positions where first protrusion 682A and second protrusion 682B face each other. Thereafter, the pipe support member 600 is moved in a direction away from the lower surface 10A (see FIG. 16). As a result, the pipe support member 600 is removed from the one-side mounting portion 81.

[0122] Fig. 23 is a diagram of the second member 720 as viewed from the direction indicated by the arrow XXIII in Fig. 20. In other words, Fig. 23 is a diagram showing the inner surface 720A of the second member 720. As described above, the second member 720 also has a circular through hole 686 formed therein, and further has two grooves 687 (first groove 687A, second groove 687B) extending from this through hole 686. Furthermore, inner surface 720A of second member 720 is provided with two rotation restricting projections 711 that protrude in a direction away from inner surface 720A. Furthermore, an edge portion 712 located on the side of the first groove 687A and the second groove 687B of the inner surface 720A of the second member 720 is also provided with an edge portion protrusion 713 that protrudes in a direction away from the inner surface 720A.

[0123] Figures 24(A) and (B) are diagrams for explaining the attachment of the pipe support member 600 to the other-side attachment portion 82 (see Figure 16). Note that Figures 24(A) and (B) only show the second member 720 among the members constituting the pipe support member 600. Also, Figures 24(A) and (B) show the second member 720 as viewed from below in the vertical direction. In this embodiment, when the piping support member 600 is attached to the other-side mounting portion 82 (see Figure 16), first, the piping support member 600 is positioned so that the mounting protrusion 680 and the second member 720 are in the state shown in Figure 24 (A).

[0124] In other words, when the piping support member 600 is attached to the other side mounting portion 82, the piping support member 600 is positioned so that the second surface 672 (see Figure 19) faces the other side mounting portion 82 (see Figure 16) and so that the first protrusion 682A and the second protrusion 682B are positioned at opposing positions to the first groove 687A and the second groove 687B.

[0125] Next, the pipe support member 600 (see FIG. 24(A)) is pushed out toward the mounting projection 680. In other words, the pipe support member 600 is pushed out toward the other-side mounted portion 82 (see FIG. 16). As a result, the protruding portion 681 (see FIG. 24(A)) enters the through-hole 686, and the first projection 682A and the second projection 682B enter the tube support member 600 through the first groove 687A and the second groove 687B. Furthermore, at this time, the restricting portion 684 provided on the support portion 10 side is pressed by the second member 720 and retreats.

[0126] Thereafter, the tube support member 600 is rotated so that the second member 720 rotates in one direction indicated by an arrow 24A in FIG. 24(A). In other words, in this configuration example, the pipe support member 600 is rotated in one direction with the second surface 672 (see Figure 19), which is one surface of the pipe support member 600, facing the other side mounting portion 82 (see Figure 16) and with the first protrusion 682A and the second protrusion 682B located within the pipe support member 600.

[0127] As a result, first protrusion 682A and second protrusion 682B are positioned at opposing positions on inner surface 720A of second member 720, as shown in FIG. 24(B). More specifically, first projection 682A and second projection 682B are located at opposing positions in a portion of inner surface 720A that is located around through-hole 686. This allows the piping support member 600 to be caught by the mounting protrusions 680, preventing the piping support member 600 from coming off the lower surface 10A (see FIG. 16 ) of the support portion 10. In other words, the piping support member 600 is attached to the other-side attached portion 82.

[0128] As described above, when the piping support member 600 is rotated beyond a predetermined rotation angle, the first protrusion 682A (see Figure 24(B)) and the second protrusion 682B come into contact with the rotation restricting protrusion 711, and the rotation of the piping support member 600 is restricted. Furthermore, as described above, when the piping support member 600 is rotated, the first protrusion 682A and the second protrusion 682B climb over the edge protrusion 713 (see FIG. 24(B)) provided on the second member 720. When the first protrusion 682A and the second protrusion 682B climb over the edge protrusion 713, the operating load required to rotate the piping support member 600 decreases. This allows the operator installing the piping support member 600 to recognize that installation of the piping support member 600 is complete.

[0129] In addition, in this configuration example, when the pipe support member 600 is rotated, the regulating portion 684 is positioned at a position opposite the regulating through hole 688 (see Figure 24 (B)), and the regulating portion 684 enters into the regulating through hole 688. When the restricting portion 684 enters the restricting through hole 688, the restricting portion 684 restricts the rotation of the pipe support member 600 in the direction opposite to the one direction (the rotation direction when the pipe support member 600 is attached). In other words, the rotation of the pipe support member 600 in the rotation direction of the pipe support member 600 when the pipe support member 600 is removed is restricted.

[0130] Next, removal of the pipe support member 600 from the other-side mounting portion 82 will be described. When removing the piping support member 600 from the other-side mounting portion 82, first, the regulating portion 684 (see Figure 24(B)) provided on the other-side mounting portion 82 is pressed toward the underside 10A of the support portion 10 (see Figure 16) to move the regulating portion 684 away from the movement path of the piping support member 600. In other words, the restricting portion 684 is moved to the outside of the restricting through hole 688 (see FIG. 24(B)) provided in the second member 720.

[0131] Thereafter, the pipe support member 600 shown in FIG. 24(B) is rotated clockwise in the figure. As a result, as shown in FIG. 24(A), first groove 687A and second groove 687B provided in second member 720 are positioned at positions where first protrusion 682A and second protrusion 682B face each other. Thereafter, the tube support member 600 is moved in a direction away from the lower surface 10A (see FIG. 16). As a result, the tube support member 600 is removed from the other-side mounted portion 82.

[0132] In this configuration example, the position of the through hole 686 provided in the first member 710 (see FIG. 20) coincides with the position of the through hole 686 provided in the second member 720 (see FIG. 19). In this configuration example, when the pipe support member 600 is attached to each of the one-side attachment portion 81 and the other-side attachment portion 82, the pipe support member 600 rotates about the rotation axis C shown in Fig. 19. In this configuration example, when comparing the positions in the direction perpendicular to the rotation axis C, the position of the through hole 686 of the first member 710 and the position of the through hole 686 of the second member 720 match.

[0133] In other words, in this configuration example, the through hole 686 of the first member 710 and the through hole 686 of the second member 720 are located on the rotation axis C, and the position of the through hole 686 of the first member 710 and the position of the through hole 686 of the second member 720 coincide with each other. In other words, in this embodiment, the through hole 686 of the second member 720 is located on the rear side of the through hole 686 of the first member 710. Furthermore, in this configuration example, when both the through hole 686 of the first member 710 and the through hole 686 of the second member 720 are projected onto a virtual plane H (see Figure 19) in the direction in which the rotation axis C extends and perpendicular to this rotation axis C, the position of the through hole 686 of the first member 710 and the position of the through hole 686 of the second member 720 coincide with each other.

[0134] Similarly, when comparing the positions in a direction perpendicular to the rotation axis C, the positions of the first groove 687A and the second groove 687B provided in the first member 710 (see Figure 20) coincide with the positions of the first groove 687A and the second groove 687B provided in the second member 720 (see Figure 19). In other words, when the first groove 687A and the second groove 687B of the first member 710 and the first groove 687A and the second groove 687B of the second member 720 are projected onto a virtual plane H in the direction in which the rotation axis C extends and perpendicular to this rotation axis C, the positions of the first groove 687A and the second groove 687B of the first member 710 coincide with the positions of the first groove 687A and the second groove 687B of the second member 720.

[0135] Similarly, when comparing the positions in a direction perpendicular to the rotation axis C, the position of the regulating through hole 688 provided in the first member 710 (see FIG. 20) coincides with the position of the regulating through hole 688 provided in the second member 720 (see FIG. 19). In other words, when the regulating through hole 688 of the first member 710 and the regulating through hole 688 of the second member 720 are projected onto an imaginary plane H in the direction in which the rotation axis C extends and perpendicular to this rotation axis C, the position of the regulating through hole 688 of the first member 710 and the position of the regulating through hole 688 of the second member 720 coincide.

[0136] (others) In the above, we have described a case in which one-side mounting part 41, one-side mounting part 81, other-side mounting part 42, and other-side mounting part 82 are provided on an examination table 1 having a support part 10 (see Figure 1) that is always aligned horizontally and does not change shape. However, the support section 10 may have other configurations. For example, there is also a configuration in which the backrest, which is a part of the support section 10, is movable, and a leg support section that supports the legs of the patient is movable.

[0137] In this configuration, the backrest is reclined and the leg support is raised, so that the patient P lying on his / her back is supported from below. In the examination table 1 having this configuration, as described above, one side mounting part 41, one side mounting part 81, other side mounting part 42, and other side mounting part 82 can be provided, and a common mounting body, that is, a table unit 100 and a piping support member 600, can be attached to the one side mounting part 41, one side mounting part 81, the other side mounting part 42, and the other side mounting part 82.

[0138] In other words, the support portion 10 is not limited to always being horizontal, and the shape thereof may vary. Furthermore, even in an examination table 1 having a support part 10 whose shape changes, by providing the above-mentioned one-side mounting part 41, one-side mounting part 81, other-side mounting part 42, and other-side mounting part 82, the table unit 100 and the piping support member 600 can be attached to multiple locations on one examination table 1. In addition, when one side mounting part 41 and the other side mounting part 42 are provided on the support part 10, whose shape changes, it is preferable to further provide a mechanism for keeping the table unit 100 attached to the one side mounting part 41 and the other side mounting part 42 in a horizontal position.

[0139] Alternatively, the first mounting member 210 and the second mounting member 250 may have the configurations shown in (A) and (B) of Fig. 14 (a diagram showing another configuration example of the first mounting member 210 and the second mounting member 250). Fig. 14(A) shows a top view, and Fig. 14(B) shows a front view. 14, similarly to the above, includes fixed part 210A fixed to object support base 130, and facing part 210B arranged at a position facing fixed part 210A. Furthermore, it includes connecting part 210C formed so as to be convex downward, connecting fixed part 210A and facing part 210B.

[0140] Furthermore, in this configuration example, a substantially rectangular through hole 210X is formed from the facing portion 210B to the connection portion 210C. As described above, as shown in FIG. 14(A), a first protrusion T11 and a second protrusion T12 are provided on the upper surface of the connection portion 210C.

[0141] FIG. 15 is a diagram showing another example of the configuration of the table unit 100. In FIG. In the embodiment described above, the posture of the first mounting member 210 is changed by attaching the first mounting member 210 to each of the first surface M1 and the second surface M2, which intersect with each other, but the configuration for changing the posture of the first mounting member 210 is not limited to this. In this configuration example shown in Fig. 15, there is provided an interlocking portion 210K that interlocks with the first attachment member 210. Note that Fig. 15 illustrates an example in which the first attachment member 210 and the second attachment member 250 shown in Fig. 14 are used.

[0142] The interlocking portion 210K is provided with an arc-shaped groove 210L. Furthermore, in this configuration example, two screw members 139 are provided which are attached to the lower surface 135 of the object support base 130 . In this embodiment, the two screw members 139 are passed through grooves 210L provided in the interlocking portion 210K, and the interlocking portion 210K is guided by the two screw members 139.

[0143] In this embodiment, the posture of the first attachment member 210 is changed by moving the first attachment member 210 in the width direction of the object support stage 130. Specifically, in this embodiment, when the first attachment member 210 is moved in the width direction of the object support base 130, the portion of the interlocking portion 210K in which the arc-shaped groove 210L is formed is guided by two screw members 139. As a result, the first attachment member 210 moves in the width direction of the object support stage 130 while rotating about the point indicated by reference symbol 15X. As a result, the posture of the first attachment member 210 is changed.

[0144] Furthermore, in this configuration example, a through hole 21H is formed in each of one end 21M and the other end 21N in the width direction of the interlocking portion 210K. Furthermore, a screw member 800 and a screw hole (not shown) for fixing the screw member 800 are provided in the center of the object support stage 130 in the width direction. In this embodiment, when the first attachment member 210 moves in one direction 15M, which is the width direction of the object support stage 130, the through hole 21H provided at one end 21M of the interlocking part 210K comes to be located at a position facing the screw hole. In this configuration example, the screw member 800 is passed through the through hole 21H and then fixed to the screw hole. This fixes the first attachment member 210 to the object support stage 130. Furthermore, when the first attachment member 210 moves in the opposite direction 15N in the width direction of the object support stage 130, the through hole 21H provided in the other end 21N of the interlocking part 210K is positioned at a position facing the screw hole. Also in this case, the screw member 800 is passed through the through hole 21H and then fixed to the screw hole. This fixes the first attachment member 210 to the object support stage 130.

[0145] As another configuration, the pipe support members 600 shown in FIGS. 10 to 13 and 16 to 24 may be fixed to the support portion 10 using fastening members such as screws.
