Description

[Technical field]

[0001] This invention relates to a chair for care which is composed of a buttocks support plate 3 which supports a person's buttocks from below, a thigh support plate 4 which supports the thighs from below, and a leg support plate 7 which supports the legs from below. [Background technology]

[0002] Conventionally, chairs are known that have a single flat seat surface, or a seat structure in which the top surface of the front part of the seat is vertically higher than the top surface of the center of the seat (Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2009-6023 Summary of the Invention [Problem to be solved by the invention]

[0004] This had the following drawbacks: When sitting in a chair, the buttocks and the backs of the thighs are in close contact with the seat, making it impossible to change underwear, disposable diapers or trousers while remaining in a seated position; care recipients who are unable to stand must be assisted in changing clothes by their caregivers who hold them in their arms. Assistance with changing clothes for those with fecal incontinence, washing the genitals and washing the buttocks cannot be achieved on a conventional chair, so assistance must be provided in the toilet or in bed.

[0005] Therefore, the present invention provides a care chair that allows the care recipient to change underwear, disposable diapers, and pants while remaining seated, and prevents urinary leakage. [Means for solving the problem]

[0006] The nursing chair of this invention is composed of a buttocks support plate 3 that supports the buttocks, a thigh support plate 4 that supports the thighs, and a leg support plate 7 that supports the legs, and the thigh support plate 4 is attached via a swing bracket 6 attached to a base 18 attached to the front side of the seat frame 8, and the top of the thigh support plate 4 is positioned higher than the top of the buttocks support plate 3 when horizontal, and the thigh support plate 4 is attached so that it can rotate around the connecting pin 40 of the swing bracket 6. The leg support plate 7 is attached to guide rails 5 attached to the inside of the left and right front legs 15, and is raised and lowered vertically by the driving force of a manual winch 9 or a motor. In addition, the support device of the present invention includes a support surface that supports the rear surface of the thigh of the care recipient, and has a thigh support part that supports the thigh of the care recipient, a rotating part that is connected to the thigh support part and rotates the thigh support part around a rotation axis that is the center of rotation, and a leg support part that includes a support surface on which the soles of the care recipient are placed and supports the legs of the care recipient, and when the thigh support part supports the care recipient, it rotates in the front-to-back direction of the care recipient by the rotating part, and when the leg support part has the soles of the care recipient's feet placed on it, the thigh support part is positioned such that the rear surface of the care recipient's thigh is separated from the thigh support part. Effect of the Invention

[0007] According to the present invention, trousers or underwear can be changed while sitting, so that even a person who cannot stand can change clothes by himself.

[0008] Even for those receiving a high level of care who are unable to stand, or those receiving full care, changing their clothes while sitting rather than while being held in their arms means that both the care recipient and the caregiver will expend less energy.

[0009] When putting on diapers for care recipients with a high level of care needs or for all caregivers after a bath, it is common for the diaper to be spread out on a wheelchair and for the caregiver to pick up the care recipient and transfer them to the wheelchair to put on the diaper, but even experienced caregivers have difficulty putting the diaper on properly. When putting on diaper pants, one caregiver must hold the care recipient while the other puts on the diaper, which requires the task of two caregivers, but with this chair, one caregiver can quickly and neatly put on a diaper, pants, or underwear on a care recipient. When putting on pants or underwear, it is necessary to lift the care recipient multiple times, which is very physically exhausting for both the caregiver and the care recipient, and it is common to see caregivers strain their backs from holding the care recipient. By using this chair, there is no need to change the care recipient while standing, so it is expected that the physical exhaustion of both the caregiver and the care recipient will be reduced, and fewer caregivers will strain their backs.

[0010] When someone has urinary or fecal incontinence, changing clothes is done in the toilet or in bed, but for example, if the person is unable to stand, or if the person is receiving full care, when dealing with fecal incontinence in the toilet, two caregivers are required, one to hold the person in his / her arms, while the other removes the person's trousers and disposable diaper, cleans the buttocks so as not to soil the toilet seat, and then has the person sit on the toilet seat. After that, the caregiver must wipe away any dirt from the genital area and wash the genitals by themselves, but because the thighs and buttocks of the person are in close contact with the toilet seat, it is difficult to wipe away the faeces and wash the genitals, and it is not possible to clean the dirt from the genitals and buttocks, which is time-consuming and hard work. By using this chair, the person can The caregiver's posture allows them to quickly and cleanly clean the genitals and buttocks, thereby shortening the time spent assisting. Also, when the person being cared for is prescribed a laxative such as Magmit, the stool becomes so large that it becomes contaminated up to the waist with soft or watery stool, and this takes a very long time to clean up and is difficult work, which can be very physically exhausting for both the caregiver and the person being cared for. Even in this case, if the care chair is used to treat the genitals, a single caregiver can work without having to stand, and both the caregiver and the person being cared for can assist without exhausting themselves. When washing the genitals, it is easy to reach the crotch area, making the work easy and allowing the genitals to be cleaned quickly and neatly.

[0011] The deciding factor for whether to continue providing at-home care or to place a patient in a nursing home is whether or not the patient can go to the toilet by themselves. If the patient develops fecal incontinence, it becomes difficult to provide care, and assisting with fecal incontinence becomes a burden, which is one of the main reasons why patients end up in a nursing home, even if they really want to provide at-home care. By using this chair, anyone can easily assist with fecal incontinence and dressing, which is expected to allow at-home care to be provided for as long as possible. If at-home care is provided for a long period of time, there will be no cost to place the patient in a nursing home, which will be economically beneficial for the patient and their family. For the country, if the patient does not move into a nursing home and at-home care is provided for a long period of time, the National Federation of Health Insurance Organizations will not pay subsidies to the nursing home, and in the broader picture, it is expected that the financial burden on the Ministry of Health, Labor and Welfare will be reduced. In the future, the increase in the elderly and the shortage of caregivers will become more serious, calling for improved productivity in the nursing care field. It is expected that the use of this chair will improve productivity in the nursing care field. For these reasons, the effects of this invention are enormous. [Brief description of the drawings]

[Figure 12] 11 is a diagram illustrating a first modified example of the nursing chair 1 of the second embodiment. FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS EXAMPLES

[0013] This nursing chair is composed of a buttocks support plate 3 that supports the buttocks, a thigh support plate 4 that supports the thighs, and a leg support plate 7 that supports the legs. The thigh support plate 4 is attached to a base 18 via a swing bracket 6 and rotates around a connecting pin 40 of the swing bracket 6. When the thigh support plate 4 is in a horizontal position, it is located 3 to 8 cm higher than the top of the buttocks support plate 3 that supports the buttocks. For example, when a person to be cared for sits on the chair and the caregiver When the person being cared for rests both elbows on the upper body support plate 16 and grips the front end of the upper body support plate, leaning forward, the center of gravity of the person being cared for moves forward, causing the thigh support plate to rotate forward around the pivot pin 40. As a result, a gap is created between the buttocks and the buttocks support plate 3, making it possible to quickly wipe and wash the buttocks, and when changing clothes, disposable pants can be easily pulled up and down from the back of the thigh support plate 4 to the waist of the person being cared for.

[0014] The swing bracket 6 is fixed between the upper mounting bracket 47 and the lower mounting bracket 48 by a connecting pin 40, but it is also possible to provide a plurality of connecting pin insertion holes 41 at intervals in the vertical direction so that the height of the thigh support plate 4 can be changed by changing the position of the pin.

[0015] The leg support plate 7 is attached via a carriage 13 to guide rails 5 attached to both sides inside the front leg 15, and is vertically raised and lowered by a manual winch 9. The leg support plate 7 can be raised and lowered vertically from a position just above the floor surface to the height of the seat frame 8 by the manual winch 9. A lifting means for moving it vertically using the driving force of a motor may also be used. By having the care recipient sit down and raising the leg support plate 7 to about the height of the seat frame 8, the knee joint is bent at an acute angle, creating a gap between the thigh support plate 4 and the thigh, and pants, disposable diapers, and disposable pants can be easily raised and lowered from below the knee to near the base of the thigh. Since there is a gap between the support plate 4 and the thighs, it is easy to wipe and wash the genitals. When washing, the buttocks support plate 3 has a semicircular hole centered on the center of the front end, and a waste bin 10 bucket is placed below the buttocks support plate 3, so it can be thoroughly washed using a shower. Even if the buttocks are wiped with toilet paper or tissue paper, they can be placed directly into the waste bin 10, making it hygienic and easy to clean up. In an emergency, the chair can be used as a toilet. For care recipients who are not concerned about urinary or fecal incontinence, a flat buttocks support plate 19 without holes may be used.

[0016] The upper surfaces of the buttocks support plate 3, thigh support plate 4, upper body support plate 16, and leg support plate 7 are made of expanded urethane foam or the like and are covered with a vinyl sheet or the like. The thigh support plate 4 may be formed into a semi-cylindrical shape in the front-to-back direction.

[0017] The swing bracket 6 is secured between the lower bracket mounting portion 48 and the upper bracket mounting portion 47 by a connecting pin 40, and rotates around the connecting pin 40. However, because the connecting pin 40 is fixed, the height of the thigh support plate 4 is constant; however, it is also possible to drill multiple pin insertion holes in the upper bracket mounting portion 47 and the lower bracket mounting portion 48 so that the pins can be freely inserted and removed, and by changing the insertion holes as desired, the height of the buttocks support platform can be changed.

[0018] The manual type of leg support plate in FIG. 2 is explained with reference to FIGS. The thigh support plate 4 has its forward and backward rotation range restricted by rotation stoppers 20, 21. The manual leg support plate 23 can be manually moved forward and backward on a slide rail 26 attached to a base 25 for the manual leg support plate, with the front leg 27 protruding forward.

[0019] 6 and 7 show the movement of the care recipient when using the chair, the positional relationship of the leg support plate 7, the thigh support plate 4, and the trousers (the shaded area is the trousers) (·→ indicates the movement of the waist area of ​​the trousers).

[0020] In FIG. 6a, the leg support plate 7 is at the lowest position, allowing the care recipient to sit, with the trousers positioned around the waist.

[0021] In Figure 6b, the caregiver has the care recipient rest their elbows on upper body support plate 16 and hold the front ends of upper body support plate 16, which causes the care recipient's center of gravity to move forward and thigh support plate 4 to rotate vertically, causing the care recipient's buttocks to lift and creating a space between the buttocks and buttock support plate 3, so that the waist part of the trousers, which was located at the waist, can be lowered to near the base of the thighs.

[0022] In Figure 6, C, the subject releases his / her hands from the upper body support plate 16 and sits on the chair, without changing the position of his / her trousers.

[0023] In Figure 6d, the caregiver raises the leg support plate 7 to approximately the height of the seat frame 8, causing the knees of the person being cared for to bend at an acute angle, creating a space between the thighs and the thigh support plate 4, and the waist part of the trousers, which was located near the base of the thighs, is lowered to near the ankles.

[0024] In FIG. 6e, the caregiver lowers the leg support plate 7 to near the floor, leaving the trousers in their original position.

[0025] Figure 6f shows the completion of the process of removing the pants from the ankles and taking them off.

[0026] In FIG. 7g, a subject is asked to sit on the chair without wearing trousers, with the leg support plate 7 located near the floor.

[0027] In FIG. 7h, the leg support 7, which holds the waist of the trousers down to the knees, is in the same position.

[0028] In FIG. 7i, the leg support plate 7 is raised to a height near the seat frame 8, and the waist of the trousers is brought from the knees to near the thighs.

[0029] In Figure 7, j, the pants remain in their original position but the leg support plate is lowered to near the floor.

[0030] In Fig. 7k, leg support plate 7 remains in the same position, and the caregiver has the cared person rest both of their elbows on upper body support plate 16 and hold the front ends of the upper body support plate. This causes the cared person's centre of gravity to move forward and thigh support plate 4 to rotate vertically forward, causing the cared person's buttocks to lift and creating a space between the buttocks and buttock support plate 3. As a result, the waist part of the trousers, which was near the thighs, is brought up to waist position.

[0031] At l in FIG. 7, the leg support plate 7 is lowered to near the floor, completing the process of putting on pants. EXAMPLES

[0032] Next, the configuration of the nursing chair 1 in Example 2 will be described with reference to Fig. 8 to Fig. 11. In Example 2, elements having substantially the same functions and configurations as those in Example 1 are denoted by the same reference numerals, and duplicated descriptions will be omitted. FIG. 8 is a perspective view illustrating the nursing chair 1 in the second embodiment. 8, the nursing chair 1 of this example has a leg support section 110, a thigh support section 120, a buttock support section 130, a positioning section 140, and a frame 160. The nursing chair 1 of this example is an example of the support tool according to the present invention, and the above-mentioned Example 1 is also an example of the support tool.

[0033] The leg support part 110 is an example of the leg support part according to the present invention, and is a unit that includes a support surface large enough to support the soles of the feet of the care recipient and supports the legs of the care recipient. The leg support part 110 includes a leg support plate 7, a leg support slide rail 26, legs 117, and wheels 118. The leg support plate 7 is a support member that includes a support surface (support surface 7A) large enough to support a part or the whole of the sole of the care recipient, and supports the legs of the care recipient. The leg support plate 7 is installed at a position where the rear surface of the thigh of the care recipient is separated from the support surface (support surface 7A) of the thigh support plate 7 described later when the sole of the care recipient is placed on the leg support plate 7. In this example, the leg support plate 7 is located below the thigh support plate 4 (lower than the thigh support plate 4) and in front of the care recipient when the sole of the care recipient is placed on the leg support plate 7. The leg support plate 7 is installed so that the distance between it and the thigh support plate 4 can be changed relatively. The leg support plate 7 in this example is installed so as to be movable in the front-rear direction of the care recipient via the leg support slide rails 26 and the wheels 118, and the distance between it and the thigh support plate 4 in the front-rear direction can be changed.

[0034] The leg support slide rails 26 are provided in pairs on a frame 160, which will be described later, and serve to allow the leg support plate 7 to move in the front-rear direction of the care recipient. The legs 117 are columnar members, one end of which is connected to the leg support plate 7, and the other end of which is connected to wheels 118 (described later). By appropriately changing the length of the legs 117, the installation position of the leg support plate 7 can be changed in the vertical direction or above and below the care recipient. The wheels 118 are undercarriage members that enable the leg support plate 7 to move, and for example, existing casters or the like can be adopted.

[0035] The thigh support 120 is an example of a thigh support according to the present invention, and is a support member that includes a support surface that supports the rear surface of the thigh of the care recipient and supports the thigh of the care recipient. The thigh support 120 is installed so as to be movable in the up and down direction along with the forward and backward movement of the care recipient. In other words, the thigh support 120 is installed so as to be movable in the forward and upward diagonal direction and the backward and downward diagonal direction of the care recipient. For example, the thigh support 120 is installed so as to be movable upward in the forward direction of the care recipient within an angle range of 10 degrees to 20 degrees with respect to a reference plane including a reference point based on a predetermined position within the plate surface of the buttocks support plate 19, and in this example, it is installed so as to be movable upward at an angle of 15 degrees in the forward direction of the care recipient. The thigh support portion 120 includes a thigh support plate 4, a swing bracket 6, a thigh support plate rear rotation stopper 21, and a thigh support plate base 18. The thigh support plate 4 includes a support surface (support surface 4A) that supports the rear surfaces of the thighs of the care recipient, and supports the thighs of the care recipient with the support surface 4A. When supporting the care recipient, the thigh support plate 4 rotates in the front-to-rear direction of the care recipient by a swing fitting 6, which will be described later. In addition, when the thigh support plate 4 supports the care recipient, the thigh support plate 4 is installed so that the distance between the thigh support plate 4 and the leg support plate 7 can be changed relatively in the front-to-rear direction of the care recipient. Moreover, the thigh support plate 4 is located higher than the buttock support plate 19. When the height of the care recipient is 150 cm to 190 cm and the seat surface (support surfaces 19A, 19B) of the buttock support plate 19 is set within a range of 36 cm to 47 cm from the installation surface of the care chair 1, the height of the thigh support plate 4 is set within a range of 39 cm to 57 cm, specifically, 39 cm to 54 cm, from the installation surface of the care chair 1 when the thigh support plate 4 is rotated forward and backward to a horizontal position, for example, when the height of the care recipient is 150 cm to 190 cm and the seat surface (support surfaces 19A, 19B) of the buttock support plate 19 is set within a range of 36 cm to 47 cm from the installation surface of the care chair 1. In other words, the support surface 4A of the thigh support plate 4 is located above the support surfaces 19A, 19B of the buttock support plate 19 by 3 cm to 10 cm, specifically, by 3 cm to 7 cm.

[0036] The swing fitting 6 is an example of a rotating part according to the present invention, and is a rotating member that is connected to the thigh support plate 4 and rotates the thigh support plate 4 around a rotation axis that serves as the center of rotation in the front-rear direction of the care recipient when supported by the thigh support plate 4. The swing fitting 6 rotatably connects the thigh support plate 4 to a thigh support plate base 18, which will be described later.

[0037] The thigh support plate rotation rear stopper 21 (hereinafter, stopper 21) is a member that restricts the rotational range of the thigh support plate 4 that rotates in the front-rear direction of the care recipient. Thigh support plate base 128 (hereinafter, base 128) is a base that supports the thigh support plate 4. Base 128 also includes an engagement portion 18A that engages with a position adjustment portion 140, which will be described later. Engagement portion 18A is a protruding portion that protrudes from base 128.

[0038] The buttocks support section 130 is an example of a buttocks support section according to the present invention, and is a support member that is located below the thigh support plate 4 of the thigh support section 120 and supports the buttocks of the care recipient. The buttocks support section 130 includes a buttocks support plate 19 that is plate-shaped. The buttocks support plate 19 is a U-shaped member that includes a plate material including rectangular support surfaces (buttocks support surfaces 19A and 19B) and legs protruding in the same direction from both ends of the plate material. The buttocks support plate 19 also includes a first buttocks support surface 19A that supports the buttocks of the care recipient, and a second buttocks support surface 19B that is provided at a position different from the first buttocks support surface 19A and supports the buttocks of the care recipient. The buttocks support plate 19 is detachably installed on the frame 160, and can be changed to the first buttocks support surface 19A or the second buttocks support surface 19B depending on the surface that supports the buttocks of the care recipient. The buttocks support plate 19 is located below the thigh support plate 4 and supports the buttocks of the care recipient. The buttocks support plate 19 is installed at a height such that the buttocks of the care recipient are separated from the buttocks support plate 19 when the thigh support plate 4 supports the care recipient and the thigh support plate 4 is rotated in the forward direction of the care recipient by the swing metal fitting 6. For example, the seat height of the buttocks support plate 19, in other words the height position of the first buttocks support surface 19A or the second buttocks support surface 19B in the vertical direction of the care recipient, is set in the range of 36 cm to 48 cm from the installation surface of the care chair 1 when the height of the care recipient is 150 cm to 190 cm, for example, and is approximately 1 / 4 times the height of the care recipient.

[0039] The positioning portion 140 is an example of a positioning portion according to the present invention, and is a holding member for setting the thigh support portion 120 at a predetermined position in the front-rear and up-down directions of the care recipient supported by the thigh support portion 120. The positioning portions 140 are set in pairs on the frame 160, and include a positioning member 142A and a positioning member 142B. The positioning members 142A and 142B have substantially the same configuration, and are simply referred to as a positioning member 142 when there is no need to distinguish them. The positioning member 142 sets the thigh support portion 120 at a predetermined target position in the front-rear and up-down directions of the care recipient supported by the thigh support plate 4. The positioning member 142 has a plurality of grooves 143 that engage with the engagement portion 18A of the base 128 at a plurality of positions, and sets the thigh support plate 4 at a position corresponding to the position of the groove that engages the engagement portion 18A.

[0040] The frame 160 includes the backrest 17 , a framework 162 , a base 167 , and wheels 168 . The backrest 17 is attached to the framework 162 and supports the back of the care-receiver. The backrest 17 includes a first backrest 17A that functions as a backrest and a handle, and a second backrest 17B that is installed so as to be rotatable about a rotation axis. The framework 162 is a basic structural part of the nursing chair 1, and in this example, it is the skeleton of the chair. In this example, the framework 162 connects the backrest 17, the positioning part 140, and the base 167. The framework 162 has an outer width smaller than the width of the toilet, and an inner width large enough to fit the toilet inside. Base 167 is plate-shaped, with framework 162 connected to one side and wheels 168 connected to the other side. In order not to interfere with the toilet bowl, base 167 has a U-shaped cutout portion in the thickness direction of the plate surface that corresponds to the external shape of the toilet bowl. The wheels 168 are chassis members that enable the frame 160 to move, and for example, existing casters or the like can be used.

[0041] Next, a detailed example of the position adjustment of the thigh support part 120 will be described. Figure 9 is a diagram illustrating in detail the position adjustment of thigh support part 120. Figure 9(A) is a diagram showing thigh support part 120 installed diagonally upward, and Figure 9(B) is a diagram showing thigh support part 120 installed diagonally downward. As shown in FIG. 9, the caregiver moves thigh support section 120 obliquely upward or downward from the care recipient, and engages engagement section 18A with a predetermined groove 143 of positioning member 142 to fix thigh support section 120 in place. As shown in Fig. 9(A), for example, when engaging portion 18A is engaged with groove 143A, thigh support portion 120 can place thigh support plate 4 diagonally downward from the care recipient. Also, as shown in Fig. 9(B), for example, when engaging portion 18A is engaged with groove 143E, thigh support portion 120 can place thigh support plate 4 diagonally upward from the care recipient. This makes it possible to adjust the height and front-to-back position of thigh support plate 4 according to the leg length relative to the height of the care recipient. From the viewpoints of operability for the caregiver and reduction of fear for the care recipient, thigh support section 120 is installed so that support surface 4A of thigh support section 120 is inclined forward at an angle (angle A) of 10 degrees to 15 degrees, specifically 10 degrees to 13 degrees, from the horizontal state when thigh support section 120 is fully rotated forward of the care recipient. By inclining support surface 4A forward from the horizontal state at an angle of 10 degrees to 15 degrees, thigh support section 120 can move the buttocks of the care recipient away from buttock support section 130 more efficiently.

[0042] Next, a diagram illustrating details of height adjustment of the hip support portion 130 will be described. Fig. 10 is a diagram illustrating the details of height adjustment in the buttocks support part 130. Fig. 10(A) is a diagram illustrating a state in which the first buttocks support surface 19A side is facing, and Fig. 10(B) is a diagram illustrating a state in which the second buttocks support surface 19B side is facing. 10, the support surface 4A of the thigh support plate 4 is located 3 cm to 10 cm above the support surface of the buttock support plate 19. If the separation distance between the support surface 4A of the thigh support plate 4 and the support surface of the buttock support plate 19 is less than 3 cm, the thigh support plate 4 is difficult to rotate in the front-rear direction, and the buttocks are difficult to separate from the buttock support plate 19 even after the thigh support plate 4 rotates forward. If the separation distance between the support surface 4A of the thigh support plate 4 and the support surface of the buttock support plate 19 exceeds 10 cm, the difference before and after the rotation becomes large, which may frighten the care recipient, or a force is required to rotate the thigh support plate 4 in the front-rear direction, which may increase the workload of the care recipient or the caregiver. Therefore, even if thigh support portion 120 is supporting the care recipient, thigh support plate 4 can be rotated in the front-rear direction with a slight shift in the center of gravity within a range of 3 cm to 10 cm. Furthermore, the buttocks support plate 19 can be set at a plurality of positions for the installation position of the support surface of the buttocks support plate 19 relative to the support surface 4A of the thigh support plate 4. 10(A), the nursing chair 1 is in a state where the first buttock supporting surface 19A of the buttock supporting plate 19 and the supporting surface 4A of the thigh supporting plate 4 at the thigh supporting portion 120 support the care recipient (referred to as pattern A). At this time, the separation distance between the first buttock supporting surface 19A and the supporting surface 4A of the thigh supporting plate 4 in the horizontal position is set to separation distance D1. For example, since the supporting surface 4A of the thigh supporting plate 4 is located above the supporting surface 19A of the buttock supporting plate 19 by a range of 6 cm to 10 cm, the separation distance D1 is 6 cm to 10 cm. 10(B), the nursing chair 1 is in a state where the second buttock supporting surface 19B of the buttock supporting plate 19 and the supporting surface 4A of the thigh supporting plate 4 at the thigh supporting portion 120 support the care recipient (referred to as pattern B). At this time, the separation distance between the second buttock supporting surface 19B and the supporting surface 4A of the thigh supporting plate 4 in the horizontal position is set as separation distance D2. For example, since the supporting surface 4A of the thigh supporting plate 4 is located above the supporting surface 19B of the buttock supporting plate 19 by a range of 3 cm or more and less than 6 cm, the separation distance D1 is 3 cm or more and less than 6 cm. Therefore, the separation distance D1 in the case of pattern A is longer than the separation distance D2 in the case of pattern B. In other words, in pattern A, the support surface of the buttocks support plate 19 and the support surface of the thigh support plate 4 are spaced apart more than in pattern B. In this way, because the separation distance D1 and the separation distance D2 are different, when putting on or taking off clothes or underwear worn on the lower body, the caregiver can use the first buttock supporting surface 19A and the second buttock supporting surface 19B depending on the degree to which the buttocks of the cared person are separated from the buttock supporting material 19. Furthermore, the caregiver can appropriately change the separation distance D between the thigh supporting plate 4 and the buttock supporting plate 19 by moving the thigh supporting portion 120 diagonally upward and forward or downward and rearward from the cared person.

[0043] Fig. 11 is a diagram illustrating a state in which the nursing chair 1 in Example 2 is in use. Fig. 11(A) and Fig. 11(B) are a side view and a plan view illustrating a state in which the nursing chair 1 is installed in a toilet, and Fig. 11(C) is a diagram illustrating a state in which the buttocks support part 130 is removed. As shown in Fig. 11(A) and Fig. 11(B), the nursing chair 1 is in a state before and after the care recipient uses the toilet, and is set up by the caregiver, for example, approaching the toilet from the rear side of the nursing chair 1. The set nursing chair 1 has a frame 160 with an outer width smaller than the width of the toilet and an inner width large enough to fit the toilet inside, so that it can be placed in the toilet. The thigh support part 120 and the buttocks support part 130 are located above the toilet seat when the nursing chair 1 is set up in the toilet, and are set up at a height that does not contact the toilet seat. Specifically, the buttocks support part 130 is set up at a height that does not contact the toilet seat with the buttocks support surface 19A or the second buttocks support surface 19B of the buttocks support plate 19. 11(C), the care chair 1 is used when the care recipient uses the toilet and the buttocks support part 130 is removed. The caregiver can attach and detach the buttocks support part 130 from the backrest 17 side.

[0044] As described above, according to the care chair 1 of Example 2, when the cared-for person puts on or takes off clothes and underwear worn on the lower body before or after using the toilet, the legs of the cared-for person near the buttocks can be lifted, thereby efficiently assisting the person in putting on and taking off clothes and underwear and reducing the workload of the caregiver.

[0045] Next, a modification of the second embodiment will be described. In the modified example, elements having substantially the same functions and configurations as those in the above embodiment are designated by the same reference numerals and redundant description will be omitted. [Variation 1] Fig. 12 is a diagram illustrating a first modified example of the nursing chair 1 of the embodiment 2. Fig. 12(A) is a side view illustrating the support tool 200, and Fig. 12(B) is a side view illustrating the support tool 200 installed on a piece of furniture F. 12(A), the support tool 200 is one example of the support tool according to the present invention, and includes a leg support section 110, a thigh support section 120, a positioning section 140, and a frame 160. The support tool 200 has a shape similar to that of the nursing chair 1 of Example 2, with the buttocks support section 130 and a part of the frame 160 removed. As shown in FIG. 12(B), the support tool 200 is placed close to a piece of furniture F such as a chair or a bed. Thus, with the assistance device 200 of this example, even when the cared-for person is seated on furniture F such as a bed or a chair, when changing clothes or underwear worn on the lower half of the body, the legs of the cared-for person near the buttocks can be lifted, thereby enabling efficient assistance with the changing task and reducing the workload of the caregiver.
