Description

[Technical Field]

[0001] The present invention relates to an examination table. [Background technology]

[0002] In intensive care units (ICUs) at medical facilities, patients undergoing surgery spend their entire stay in bed, and some ICU beds can be transformed into a form that allows the patient to lie down in a seated position. In such beds, the portion that supports the upper body rises to form a backrest, and the portion that supports the legs bends to form a legrest. For example, Patent Document 1 listed below (hereinafter, the invention described in Patent Document 1 will be referred to as the "Publicly Known Patent Document 1 Invention") describes a technology that can be transformed into a bed position, which is a bed form, and a chair position, which is a chair form. In the chair position, a footrest rises from the back side of the tip of the legrest toward the front side.

[0003] While patients in the ICU require bed rest, those who spend long periods there experience reduced leg strength and require rehabilitation. Research has shown that simply having the soles of the feet touch the floor without walking can help prevent a decline in leg strength. Therefore, if the footrest is in contact with the soles of the feet, rehabilitation will be beneficial. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2019-526 Summary of the Invention [Problem to be solved by the invention]

[0005] However, because beds are primarily designed for patients to lie down on, even beds that can be transformed into chairs still have the necessary size and shape for a bed, just like regular beds. For example, beds in medical facilities are about 2 meters long, so even if they are transformed into chairs, the patient's feet with bent knees may not be able to reach the footrest. On the other hand, if the leg rest is short enough that the patient's feet can reach the footrest, the bed may not be long enough to be used as a bed.

[0006] The present invention has been proposed in consideration of the above-mentioned circumstances, and aims to provide an examination table that, when in bed form, can ensure an appropriate overall length for the bed, and, when in chair form, can stimulate the soles of the user's feet. [Means for solving the problem]

[0007] In order to achieve the above object, the examination table according to the present invention is an examination table that can be transformed into a bed form that supports the user in a lying position or a chair form that supports the user in a sitting position by transforming a lower limb support section that supports the lower limbs of a user, and the lower limb support section has a first lower limb support member connected to a tip end of a seat, a second lower limb support member connected to a tip end of the first lower limb support member, and a third lower limb support member connected to a tip end of the second lower limb support member, and in the chair form, the first lower limb support member is connected to a front the second lower limb support member extends downward from the tip of the seat, the second lower limb support member extends forward from the tip of the first lower limb support member, and of the second lower limb support member which was on the same plane as the first lower limb support member in the bed form, the portion closer to the first lower limb support member is positioned behind the surface of the first lower limb support member, the third lower limb support member extends forward from the tip of the second lower limb support member, and the second lower limb support member and the third lower limb support member form a footrest on which the user's feet are placed.

[0008] The examination table according to the present invention is characterized in that, in the chair form, the third lower limb support member is tilted upward by rotating relative to the second lower limb support member.

[0009] The examination table according to the present invention is characterized in that, in the chair form, the third lower limb support member is tilted downward by rotating relative to the second lower limb support member.

[0010] The examination table according to the present invention is characterized in that, in the chair form, the joint portion between the second lower limb support member and the third lower limb support member is located forward of the first lower limb support member.

[0011] The examination table according to the present invention is characterized in that the first lower limb support member has a first lower limb frame member connected to the seat portion and a first contact member attached to the first lower limb frame member and coming into contact with the user, the second lower limb support member has a second lower limb frame member connected to the first lower limb frame member and a second contact member attached to the second lower limb frame member and coming into contact with the user, and a storage recess is formed in the first lower limb frame member near the joint between the first lower limb frame member and the second lower limb frame member to store the second contact member in the chair form.

[0012] The examination table of the present invention is characterized in that, during the process of changing into the bed form or the chair form, it has a parallel link that rotates the second lower limb support member relative to the first lower limb support member while the second lower limb support member remains in a forward extended position. [Effects of the Invention]

[0013] The examination table of the present invention can be transformed into a bed form that supports the user in a lying position or a chair form that supports the user in a sitting position by transforming the lower limb support section that supports the user's lower limbs. The lower limb support section has a first lower limb support member connected to the tip of the seat, a second lower limb support member connected to the tip of the first lower limb support member, and a third lower limb support member connected to the tip of the second lower limb support member. In the chair form, the first lower limb support member extends downward from the tip of the seat, and the second lower limb support member extends forward from the tip of the first lower limb support member. In addition, of the second lower limb support member that is on the same plane as the first lower limb support member in the bed form, the part closer to the first lower limb support member is positioned behind the surface of the first lower limb support member, and the third lower limb support member extends forward from the tip of the second lower limb support member. The second lower limb support member and the third lower limb support member form a footrest on which the user's feet are placed. In the bed form, the user's legs are supported by the first lower limb support member, the second lower limb support member, and the third lower limb support member, which are aligned on the same plane. Meanwhile, in the chair form, the second lower limb support member and the third lower limb support member function as footrests that support the user's feet, and the first lower limb support member functions as a legrest that supports the user's lower legs. Here, in the chair form, the shorter the leg rest is relative to the user's lower legs, the more likely it is that the footrest will come into contact with the user's feet. Therefore, shortening the first lower limb support member allows the second lower limb support member and the third lower limb support member to come into contact with and stimulate the soles of the user's feet. Meanwhile, in the bed form, even if the first lower limb support member is short, the second lower limb support member forms part of the bed form, thereby compensating for the overall length of the bed form, ensuring an appropriate overall length for the bed form.

[0014] In addition, since the second lower-limb support member, which constitutes part of the bed form, becomes a footrest in the chair form, the footrest is made longer by the second lower-limb support member, but since part of the second lower-limb support member is hidden by the first lower-limb support member in the chair form, the overall length of the footrest is shortened by that amount. Therefore, the footrest does not become excessively long.

[0015] In the examination table according to the present invention, when in the chair configuration, the third lower-limb support member rotates relative to the second lower-limb support member, thereby tilting upward. When the third lower-limb support member, which serves as a footrest in the chair configuration, tilts upward, it comes closer to the soles of the feet and is more likely to contact the soles. Therefore, the soles of the feet of the user can be stimulated in the chair configuration.

[0016] Users' feet come in a variety of shapes, and may be deformed due to illness, etc. Therefore, in the examination table according to the present invention, in the chair form, the third lower-limb support member rotates relative to the second lower-limb support member to tilt downward. By tilting the third lower-limb support member upward or downward, the postures of the second and third lower-limb support members can be adjusted to fit the shape of the sole of the foot.

[0017] In the examination table according to the present invention, in the chair configuration, the joint between the second lower-limb support member and the third lower-limb support member is located forward of the first lower-limb support member. In the chair configuration, a portion of the second lower-limb support member is hidden behind the first lower-limb support member, so the position of the joint between the second lower-limb support member and the third lower-limb support member is closer to the first lower-limb support member, directly below or in the vicinity of the user's ankle. By locating the rotation axis of the third lower-limb support member below the ankle, the rotation of the foot around the ankle and the rotation of the third lower-limb support member are aligned vertically, and therefore the third lower-limb support member can rotate in accordance with the rotation of the foot.

[0018] In the examination table according to the present invention, the first lower limb support member has a first lower limb frame member connected to the seat portion and a first contact member attached to the first lower limb frame member and coming into contact with the user, and the second lower limb support member has a second lower limb frame member connected to the first lower limb frame member and a second contact member attached to the second lower limb frame member and coming into contact with the user, and the first lower limb frame member has an accommodation recess formed near a joint between the first lower limb frame member and the second lower limb frame member, in which the second contact member is accommodated in the chair form. In the chair form, because the second contact member is accommodated in the accommodation recess, a part of the second contact member is hidden behind the first lower limb support member. Accordingly, the joint between the second lower limb support member and the third lower limb support member is closer to the first lower limb support member and comes directly below or near the ankle of the user. By locating the rotation axis of the third lower limb support member below the ankle, the rotation of the foot around the ankle and the rotation of the third lower limb support member are aligned vertically, and therefore the third lower limb support member can rotate in accordance with the rotation of the foot. Meanwhile, in the bed form, the second contact member comes out of the accommodation recess and the entire surface of the second contact member supports the lower limb of the user, ensuring an appropriate overall length for the bed form.

[0019] The examination table according to the present invention has a parallel link that rotates the second lower-limb support member relative to the first lower-limb support member while the second lower-limb support member remains extended forward during the process of changing into the bed form or the chair form. Therefore, the examination table changes into the bed form or the chair form while the second lower-limb support member is in a horizontal or approximately horizontal position.

[0021] The following is a description of an examination table according to an embodiment of the present invention. The examination table can be changed between a bed form that supports a user (not shown) in a lying position and a chair form that supports a user in a sitting position. Figures 1 and 2 show the examination table 1 in bed form, and Figures 3 and 4 show the examination table 1 in chair form. In the following description, as shown in Figure 1, the overall length direction of the examination table 1 in bed form will be referred to as the front (Front) or rear (Back), the lifting direction will be referred to as the up (Up) or down (Down), and the width direction of the examination table 1 will be referred to as the left side (Left Side) or right side (Right Side). Also, as shown in Figure 3, in the examination table 1 in chair form, the front side as seen from a seated user (not shown) will be referred to as the front (Front) and the back side will be referred to as the back (Back).

[0022] As shown in Figures 1 to 4, the examination table 1 has a table support part 2 and a table main body part 3 connected to the top of this table support part 2. The table support part 2 has casters 4, and the examination table 1 can move freely using the casters 4. The table support part 2 has a built-in lifting device (not shown) that raises and lowers the table main body part 3, and a movable device (not shown) that changes the form of the table into a bed form or a chair form.

[0023] The table main body 3 has a seat 5 on which the user sits, a lower limb support 9 located in front of the seat 5 to support the user's lower limbs, and a backrest 6 located behind the seat 5 to support the user's upper body. A headrest 7 to support the user's head is attached to the upper front part of the backrest 6, and armrests 8 to support the user's arms are attached to the left and right sides of the backrest 6. When the movable device of the table support 2 is operated and the examination table 1 changes into a bed form, the backrest 6 reclins, the armrests 8 maintain a horizontal or approximately horizontal position, and the lower limb support 9 deforms and extends forward, so that the seat 5, backrest 6, armrests 8, and lower limb support 9 become horizontal or approximately horizontal, and a flat surface on which the user can lie down is formed on the upper surface of the table main body 3. On the other hand, when the examination table 1 is transformed into a chair form, the backrest portion 6 rises, the armrests 8 maintain a horizontal or approximately horizontal position, and the lower limb support portion 9 deforms and bends, forming a seat surface on the top surface of the table main body portion 3 on which the user can sit.

[0024] Here, the lower limb support part 9 will be described in detail with reference to the drawings. Fig. 5 shows the internal structure of the lower limb support part 9.

[0025] 1 to 5 , the lower limb support section 9 includes a first lower limb support member 10 connected to a distal end of the seat section 5, a second lower limb support member 11 connected to a distal end of the first lower limb support member 10, and a third lower limb support member 12 connected to a distal end of the second lower limb support member 11. The first lower limb support member 10 includes a first lower limb frame member 16 connected to the seat section 5 via a first joint section 13 and a first contact member 19 attached to the surface of the first lower limb frame member 16. The second lower limb support member 11 includes a second lower limb frame member 17 connected to the first lower limb frame member 16 via a second joint section 14 and a second contact member 20 attached to the surface of the second lower limb frame member 17. The third lower limb support member 12 includes a third lower limb frame member 18 connected to the second lower limb frame member 17 via a third joint section 15 and a third contact member 21 attached to the surface of the third lower limb frame member 18.

[0026] The first contact member 19, the second contact member 20, and the third contact member 21 are each shaped like a roughly rectangular plate. The first contact member 19, the second contact member 20, and the third contact member 21 are made of cushioning material and are covered with a cover because they come into contact with the user. In the chair form, the vertical length of the first contact member 19 (the front-to-back length in the bed form) is approximately the same as or shorter than the length of an adult's lower leg, for example. The front-to-back length of the second contact member 20 is shorter than the first contact member 19 and the third contact member 21. The combined front-to-back length of the second contact member 20 and the third contact member 21 is approximately the same as or longer than the length of an adult's foot, for example.

[0027] The first lower limb frame member 16 includes a pair of left and right first frame pieces 22 and a first frame plate 23 that spans between the first frame pieces 22 and is attached to the inner surfaces of the first frame pieces 22. The first frame pieces 22 are thin plates that are vertically long in the chair configuration (and longitudinally long in the bed configuration). A first frame base end 24 of each first frame piece 22, which is the upper end in the chair configuration (the rear end in the bed configuration), is connected to the seat 5 via a first joint 13. A first frame tip 25, which is the lower end (the front end in the bed configuration), is connected to a second frame piece 27 of the second lower limb support member 11 via a second joint 14. A storage recess 26 is formed in the first frame tip 25 near the second joint 14. The storage recess 26 is a portion where the first frame tip 25 is cut out along the periphery of the second joint 14.

[0028] The second lower limb frame member 17 has a second frame plate 28 and second frame pieces 27 extending downward from both left and right ends of the second frame plate 28. The second frame plate 28 is a thin plate that is long in the left-right direction. Of the second frame pieces 27, a second frame intermediate portion 29 located between the front end and rear end is connected to the first frame piece 22 of the first lower limb support member 10 via a second joint 14, and a second frame front end portion 30, which is the front end, is connected to a third frame piece 31 of the third lower limb support member 12 via a third joint 15.

[0029] The third lower limb frame member 18 has a pair of left and right third frame pieces 31 and a third frame plate 32 extending between the third frame pieces 31. The third frame pieces 31 are thin plates that are long in the front-to-rear direction. A third frame rear portion 33, which is the rear end of the third frame piece 31, is connected to the second frame piece 27 of the second lower limb support member 11 via a third joint portion 15.

[0030] Next, the parallel link mechanism 34 and ratchet mechanism 43 built into the lower limb support part 9 will be explained with reference to the drawings. Figures 6 and 7 show the interior and cross section of the examination table 1 in the bed form, and Figures 8 and 9 show the interior and cross section of the examination table 1 in the chair form. Figures 10 and 11 show a cross section of the examination table 1 in the chair form when in use.

[0031] 6 to 9, the parallel link mechanism 34 is realized by a linear actuator 35 as a drive source, the first lower limb frame member 16 and link piece 37 of the first lower limb support member 10 with the seat portion 5 as a fixed end, and the second lower limb frame member 17 of the second lower limb support member 11. The linear actuator 35 is, for example, a motor-driven, hydraulic, or pneumatic piston cylinder, and is connected to the back surface of the seat portion 5. The piston member 36 of the linear actuator 35 extends forward and is connected to the back surface of the first frame plate portion 23 of the first lower limb frame member 16. The link piece 37 is a long, thin plate parallel to the first frame piece 22. Of the link piece portion 37, the link piece base end portion 38, which is the upper end portion in chair form (rear end portion in bed form), is connected to the tip portion of the seat portion 5 via the link first joint portion 40, and the link piece tip portion 39, which is the lower end portion (front end portion in bed form), is connected to the second frame rear end portion 45, which is the rear end portion of the second frame piece portion 27 of the second lower limb frame member 17, via the link second joint portion 42.

[0032] 6 and 7, when the linear actuator 35 is operated and the piston member 36 moves rearward, the first lower limb frame member 16 is pulled rearward, causing the first lower limb frame member 16 to rotate about the first joint portion 13 as an axis (rotating counterclockwise in the figure), and to fall downward relative to the seat portion 5. Because the link piece portion 37 is connected to the first lower limb frame member 16 via the second lower limb frame member 17, in conjunction with the movement of the first lower limb frame member 16, the link piece portion 37 rotates about the first link joint portion 40 as an axis (rotating counterclockwise in the figure), and to fall downward relative to the seat portion 5. Because the second lower limb frame member 17 is connected to the first lower limb frame member 16 and the link piece 37, in conjunction with the movement of the first lower limb frame member 16 and the link piece 37, the second lower limb frame member 17 rotates relative to the first lower limb frame member 16 and the link piece 37 around the second joint 14 and the second link joint 42 (rotating clockwise in the figure). With each member acting as a parallel link mechanism 34, the second lower limb frame member 17 moves while remaining extended forward, and the examination couch 1 changes from the bed form to the chair form (see Figures 8 and 9). Because the third lower limb frame member 18 is on the same plane as the second lower limb frame member 17, the third lower limb frame member 18 also remains extended forward during the process of changing from the bed form to the chair form.

[0033] On the other hand, in the chair form shown in Figures 8 and 9, when the linear actuator 35 is operated and the piston member 36 moves forward, the first lower limb frame member 16 is pushed forward, and the link piece portion 37 and the second lower limb frame member 17 are linked to the movement of the first lower limb frame member 16. With each member acting as a parallel link mechanism 34, the second lower limb frame member 17 and the third lower limb frame member 18 move while remaining stretched forward, and the examination table 1 changes from the chair form to the bed form (see Figures 6 and 7).

[0034] 10 and 11, the third joint 15, which is the connecting portion between the second lower limb frame member 17 and the third lower limb frame member 18, is realized by a ratchet mechanism 43. That is, the third lower limb frame member 18 rotates about the third joint 15 as an axis, and thereby tilts upward or downward relative to the second lower limb frame member 17, based on the position when the third frame plate 32 of the third lower limb frame member 18 is on the same plane as the second frame plate 28 of the second lower limb frame member 17. If the position when the third frame plate 32 is on the same plane as the second frame plate 28 is assumed to be zero degrees, the position where the angle is negative is set as the initial position (see FIG. 11). From this initial position, the angle of the third lower limb frame member 18 relative to the second lower limb frame member 17 changes stepwise, and the third lower limb frame member 18 stops at the desired angle. When the predetermined angle is exceeded, the third lower limb frame member 18 can rotate (rotate counterclockwise in the drawing) toward the original initial position.

[0035] Next, the operation of the lower limb support unit 9 will be described with reference to the drawings together with the functions and effects of this embodiment. Fig. 12 shows a first use state in the chair form, and Fig. 13 shows a second use state in the chair form.

[0036] As shown in FIGS. 1 and 2, in the bed configuration, the first lower-limb support member 10 extends forward from the tip of the seat 5, the second lower-limb support member 11 extends forward from the tip of the first lower-limb support member 10, and the third lower-limb support member 12 extends forward from the tip of the second lower-limb support member 11. On the other hand, as shown in FIGS. 3 and 4, in the chair configuration, the first lower-limb support member 10 extends downward from the tip of the seat 5, the second lower-limb support member 11 extends forward from the tip of the first lower-limb support member 10, and the third lower-limb support member 12 extends forward from the tip of the second lower-limb support member 11. During the process of changing from the bed configuration to the chair configuration or from the chair configuration to the bed configuration, the parallel link mechanism 34 operates, causing the second lower-limb support member 11 to rotate relative to the first lower-limb support member 10 while remaining extended forward. The third lower-limb support member 12 is on the same plane as the second lower-limb support member 11. Therefore, the second lower limb support member 11 and the third lower limb support member 12 appear to maintain a horizontal or approximately horizontal position, and the examination table 1 changes into a bed form or a chair form.

[0037] 3 and 4, in the chair form, the first lower-limb support member 10 serves as a leg rest that supports the user's lower legs, and the second lower-limb support member 11 and the third lower-limb support member 12 serve as foot rests that support the user's feet. Here, since the first lower-limb support member 10 is, for example, about the same length as an adult's lower leg or shorter, the second lower-limb support member 11 and the third lower-limb support member 12 come into contact with the soles of the user's feet, stimulating the soles. Even if the first lower-limb support member 10 is short, in the bed form, the second lower-limb support member 11 forms part of the bed form, thereby compensating for the overall length of the bed form, ensuring an appropriate overall length for the bed form.

[0038] In the chair form, of the second lower limb support member 11 that was on the same plane as the first lower limb support member 10 in the bed form, a portion of the second contact member 20 closer to the first lower limb support member 10 (hereinafter, the portion of the second contact member 20 closer to the first lower limb support member 10 will be referred to as the "received portion 44") is accommodated in the accommodation recess 26 of the first lower limb support member 10, and is thereby positioned behind the surface of the first contact member 19 of the first lower limb support member 10 and directly below the first contact member 19. Furthermore, in the chair form, the received portion 44 is positioned behind the surface of the first lower limb frame plate portion 23 and behind the second joint portion 14. In other words, although the footrest is made longer by the second lower limb support member 11, a portion of the second lower limb support member 11 is hidden by the first lower limb support member 10 in the chair form, and therefore the overall length of the footrest is shortened by that amount. Therefore, the footrest does not become excessively long.

[0039] In the chair form, since the accommodated portion 44 is accommodated in the accommodation recess 26 of the first lower limb support member 10 and is hidden behind the first lower limb support member 10, the third joint portion 15 approaches the first lower limb support member 10, is forward of the surface of the first contact member 19, and is located directly below or in the vicinity of the ankle of the user seated on the examination table 1. By locating the rotation axis of the third lower limb support member 12 below the ankle, the rotation of the foot around the ankle and the rotation of the third lower limb support member 12 are aligned in the vertical direction, and the third lower limb support member 12 can rotate in accordance with the rotation of the foot.

[0040] 12, in the chair form, the third lower-limb support member 12 rotates about the third joint 15, thereby tilting upward relative to the second lower-limb support member 11. The upwardly tilted third lower-limb support member 12 is closer to the soles of the feet and therefore more likely to come into contact with the soles. Therefore, the soles of the feet of the user are stimulated in the chair form.

[0041] 13, in the chair form, the third lower limb support member 12 rotates around the third joint portion 15 as an axis, thereby tilting downward relative to the second lower limb support member 11. Even if the user's feet are deformed due to illness or the like, the posture of the second lower limb support member 11 and the third lower limb support member 12 tilts upward or downward, so that the posture of the second lower limb support member 11 and the third lower limb support member 12 matches the shape of the sole of the foot, stimulating the sole of the foot.

[0042] The posture of the examination table 1 can be arbitrarily changed by operation by a medical professional or the like (not shown), or can automatically change to a predetermined posture. Therefore, for example, as shown in FIGS. 14 to 16, it can also be changed to a second chair form. In the second chair form, the backrest 6 is more reclined than in the chair form, and the lower limb support member 9 is located further forward than in the chair form, compared to the chair form (see FIG. 4). Even in the second chair form, the accommodated portion 44 of the second lower limb support member 11 is accommodated in the accommodation recess 26 of the first lower limb support member 10 and is hidden behind the first lower limb support member 10. Furthermore, the third lower limb support member 12 rotates about the third joint 15, thereby tilting upward or downward relative to the second lower limb support member 11.

[0043] In other embodiments of the present invention, the third crus support member does not rotate and does not tilt upward or downward. In another embodiment, the first lower limb support member does not have a receiving recess formed therein, and therefore, in this embodiment, the portion of the second lower limb support member that is closer to the first lower limb support member is not positioned behind the surface of the first lower limb support member. In another embodiment, there is no parallel linkage.

[0044] Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments, and various design modifications can be made to the present invention without departing from the scope of the claims.
