The present invention relates to a medical chair device.

BACKGROUND ART Conventionally, there is known a chair device that can change the posture of a seated person to various postures from a sitting posture to a recumbent posture. For example, Patent Document 1 discloses a multipurpose chair that can be deformed to a sitting mode in which a frame supporting a seated person's legs is in a front downward direction or a bed mode in which the frame is substantially horizontal.

JP, 2003-93189, A

Since the multipurpose chair disclosed in Patent Document 1 supports the legs of the seated person so that the legs of the seated person are directed to the lower front side in the sitting mode, the movement of the center of gravity of the seated person sitting in the multipurpose chair when standing up is large, In addition, if the user tries to sit down from the front of the multipurpose chair, the operation will be such that the user falls down into the multipurpose chair. For this reason, the multipurpose chair disclosed in Patent Document 1 requires consideration such as standing upright toward the side of the seating surface of the multipurpose chair.

By the way, there are cases where a patient sitting on a medical chair device is fitted with a medical device or the like and treated such as a medical treatment. In this case, if the treatment takes a long time, the seated person (patient) may need to leave the seat while wearing the medical device or the like. For example, when a seated person leaves the seat while receiving an intravenous drip, in the multipurpose chair disclosed in Patent Document 1, care must be taken not to catch the tube of the infusion kit or hit the infusion stand. The sitting and standing motions are complicated and the burden is heavy.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a medical chair apparatus with a small burden in standing and sitting motions.

One aspect of the present invention is a seat body having a seat surface, a side plate that is a plate shape substantially perpendicular to the seat surface and is adjacent to the seat body, and is arranged on the front side of the seat body. A lower leg receiving portion that has a lower leg receiving surface that supports the lower leg, is provided at the base end portion on the side of the seat body and is tiltable about a rotation axis, and a backrest arranged on the rear side of the seat body. A supporting plate disposed so as to overlap the side plate, and an elbow rest having an elbow rest main body supported on an upper side portion of the supporting plate , wherein the lower leg receiving portion has the lower leg receiving surface as the seat body. From the leg up position extending from the front to the front, the lower leg receiving surface is inclined from the front side toward the rear side from the base end portion toward the front end portion, and the lower leg is inside the contour of the side plate when viewed from the side. The side plate is tiltable between a storage position in which the receiving portion is stored, and the side plate is viewed from a side, and substantially follows the lower leg receiving surface in a state where the lower leg receiving portion is stored in the storage position. It is a medical chair device having a front side portion inclined with respect to a seat surface.

In the medical chair device of the above aspect, a space into which the heel of a seated person enters is formed in front of the lower leg receiving surface with the lower leg receiving portion stored in the storage position. Therefore, according to the medical chair device of the above aspect, the amount of movement of the center of gravity of the occupant when the occupant tries to stand up from the medical chair device is small, and the burden on the occupant during sitting and standing is small. ..

Further, a plurality of the side plates may be provided so as to be separated from each other with the seat body interposed therebetween.
In this case, regardless of whether the infusion stand or the infusion kit is placed on the left or right side of the seating surface of the medical chair device, the infusion kit should be set so that the tube of the infusion kit and the legs of the infusion stand are less likely to interfere with the lower leg receiving portion. The tubes and legs of the infusion stand can be protected by multiple side plates.

Further, the lower leg receiving portion may be capable of tilting downward from the leg-up position by more than 90° around the rotation axis.
In this case, since the lower leg receiving portion is stored so that there is a space for inserting the heel behind the seated person just below the knee, it is easy to sit and stand up.

According to the medical chair device of the present invention, since the lower leg receiving portion can be stored in the storage position, the burden on the standing and sitting motion is small.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the front-back, left-right, and up-down directions in the following description are based on the direction viewed from a seated person who is seated with his back on the back of the chair.

FIG. 1 is a perspective view of the medical chair apparatus of this embodiment. FIG. 2 is a side view of the chair device. FIG. 3 is a front view of the chair device. FIG. 4 is a diagram for explaining the operations of the lower leg receiving portion and the backrest of the chair device.
The chair apparatus 1 of the present embodiment shown in FIG. 1 is a reclining chair used, for example, for medical treatment or nursing care, so that a seated person can take various postures even when sitting for a long time. A seated person can electrically adjust the posture and position of each part of the chair by electric power.

As shown in FIGS. 1 to 3, the chair device 1 includes a frame-shaped base frame 2 installed on a floor surface F (see FIG. 2), and a chair body 3 supported by the base frame 2 so as to be able to move up and down. And The chair body 3 includes a seat body 4, a backrest 5, lower leg receiving portions 6, and left and right elbow rests 7.

The seat body 4 forms a substantially horizontal seat surface 8 (upper surface) having a rectangular shape in plan view. Left and right side plates 9 (first side plate 91, second side plate 92) are arranged on the left and right sides of the seat body 4. The seat body 4 is arranged between the upper side portions of the left and right side plates 9. The left right side plate 9 has a plate shape that is substantially vertical to the seat surface 8. Further, the upper sides 9a of the left and right side plates 9 are located below the seat surface 8 in a side view. Further, the front side portion 9b located on the front side of the left and right side plates 9 is inclined forward so as to go forward as it goes upward in a side view. The lower leg receiving portion 6 in the storage position is disposed between the front side portions 9b of the left right side plate 9 that are inclined forward. The seat body 4, the left and right side plates 9 and the lower leg receiving portion 6 form a box-shaped mechanism accommodating portion 10. Inside the mechanism accommodating portion 10, various drive mechanisms such as an elevating device for elevating the chair body 3 and a reclining mechanism for reclining the backrest 5 are accommodated (all not shown).

The support plates 11 of the left and right elbow rests 7 are arranged outside the left and right side plates 9 so as to overlap each other. The lower side portion 11c of the support plate 11 is formed substantially horizontally in a side view. Further, the front side portion 11b of the support plate 11 is inclined forward so as to go forward as it goes upward from below in a side view. Further, the rear side portion 11d of the support plate 11 is inclined rearward so as to go rearward from the lower side to the upper side in a side view. A substantially horizontal elbow rest body 12 is supported on the upper side portion 11 a of the support plate 11.

The elbow of the seated person can be placed on the elbow rest body 12 of the left and right elbow rest 7. The left and right elbow rests 7 can be raised and lowered, for example, in conjunction with the reclining operation of the backrest 5 so that the elbow rest main body 12 can be raised and lowered (see FIG. 4).

As shown in FIGS. 3 and 4, the lower leg receiving portion 6 has a lower leg receiving surface 6c on which the legs of a seated person are placed. The lower leg receiving portion 6 is located between the storage position P1 which is sandwiched between the front side portions 9b of the left and right side plates 9 below the front of the seat body 4 and the leg-up position P2 which is arranged substantially horizontally in front of the seat body 4. It is possible to tilt with. The lower leg receiving portion 6 is supported by the front portion of the mechanism accommodating portion 10, and is tiltable between the retracted position P1 and the leg up position P2 by the operation of the drive mechanism in the mechanism accommodating portion 10. In the present embodiment, the lower leg receiving portion 6 can be tilted from the leg-up position P2 to the retracted position P1 by more than 90° about the adjacent portion between the lower leg receiving portion 6 and the seat body 4 as an axis. In a state where the lower leg receiving portion 6 is stored in the storage position of the lower leg receiving portion 6, the lower end 6a of the lower leg receiving portion 6 is closer to the upper end 6b of the lower leg receiving portion 6 (adjacent portion between the lower leg receiving portion 6 and the seat body 4). Also, the lower leg receiving portion 6 is stored so as to be inclined with respect to the seat surface 8 so as to be located rearward (on the backrest 5 side). The lower leg 6a of the lower leg receiving portion 6 can be retracted such that the lower end 6a thereof is located rearward of the upper end 6b of the lower leg receiving portion 6, so that a space for putting the heel of the seated person in the lower front of the seat body 4. A1 (see FIG. 2) can be generated. As a result, when the lower leg receiving portion 6 is stored in the storage position, the occupant does not have to move the center of gravity when sitting and standing up, so that the person can easily sit and stand up.

Further, since the lower leg receiving portion 6 is sandwiched between the left and right side plates 9 when the lower leg receiving portion 6 is in the storage position, it is difficult for an object to be sandwiched between the lower leg receiving portion 6 and the left and right side plates 9. For example, when the chair device 1 of the present embodiment is used, the tube 20 of the infusion set used together with the chair device 1 is pulled up to the vicinity of the lower leg receiving portion 6 when the seated person stands up with the infusion stand 21. At this time, since the left and right side plates 9 are provided, the tube 20 does not come into contact with the lower leg receiving portion 6, so that the tube 20 may be caught on the lower leg receiving portion 6 while the seated person holds the infusion stand 21 and stands up. Absent.

It is not essential that the lower leg receiving surface 6c is completely stored between the left and right side plates 9. That is, when the lower leg receiving portion 6 is in the storage position P1, at least a part of the lower leg receiving portion 6 is stored inside the contour of the left and right side plates 9 in the side view and at the bottom of the seat body 4. For example, when the lower leg receiving portion 6 is in the retracted position, the back surface 6d opposite to the lower leg receiving surface 6c may be located rearward of the front side portions 9b of the left and right side plates 9 in a side view.

As shown in FIG. 4, the backrest 5 is arranged on the opposite side of the lower leg receiving portion 6 with the seat body 4 interposed therebetween. The backrest 5 is tiltable between an upright position (see FIG. 2) that stands upright behind the seat body 4 and a reclining position (see FIG. 4) that is arranged substantially horizontally behind the seat body 4. To be done. The backrest 5 is supported by the rear portion of the mechanism housing portion 10 and is tiltable between the upright position and the reclining position by the operation of the reclining mechanism in the mechanism housing portion 10.

The backrest 5 extends above a backrest surface 13 (front surface) that supports the back of a seated person, and a headrest 14 is integrally formed above the backrest surface 13. The front surface of the headrest 14 is a head supporting surface 16, and the position immediately before the head supporting surface 16 is the head position of the seated person. In the present embodiment, it can be said that the headrest 14 is a part (upper part) of the backrest 5. A cushion may be separately installed on the head supporting surface 16.

On the left and right side portions of the headrest 14, a pair of left and right side shield portions 15 standing upright forward and leftward and rightward are integrally formed. As a result, the field of view of the head of the seated person is appropriately shielded, and the line of sight from the same direction is appropriately shielded. The left and right side shields 15 have a built-in speaker that emits sound toward the head position.

The operation of the chair device 1 of this embodiment will be described.
The chair device 1 becomes a chair by setting the backrest 5 in the standing position and the lower leg receiving portion 6 in the storage position (see FIG. 2 ). At this time, the elbow rest 7 is in the raised position, and the elbow and forearm of the seated person in the sitting posture are placed on the elbow rest 7 so that medical treatment such as chemotherapy can be continued.
In the chair device 1, the backrest 5 is in the reclining position and the lower leg receiving portion 6 is in the leg up position, so that the seat body 4, the backrest 5 and the lower leg receiving portion 6 are connected in a substantially horizontal manner as a bed. (See FIG. 4). At this time, the elbow rest 7 is in the lowered position, and the elbow and the forearm of the seated person in the recumbent posture are placed on the elbow rest 7 so that the medical procedure before reclining can be continued.

In this way, the chair device 1 can change the posture of the seated person to various postures from the sitting posture to the recumbent posture. Although the backrest 5, the lower leg receiving portion 6 and the elbow rest 7 may be individually adjustable in arbitrary positions, when the seated person is subjected to medical treatment such as chemotherapy, reclining of the backrest 5 is performed. The raising and lowering of the elbow rest 7 may be performed in conjunction with each other.

In addition, medical treatment such as chemotherapy may take a long time, and the seated person may need to be separated from the chair apparatus 1. In this case, as shown in FIG. 2, by setting the backrest 5 of the chair device 1 to the standing position and the lower leg receiving portion 6 to the retracted position, the seated person can easily stand up from the chair device 1 and move forward. can do. In addition, for example, when a seated person sitting on the chair apparatus 1 leaves the chair apparatus 1 while performing infusion, the seated person may hold the infusion stand 21 and move together with the infusion stand 21. In this case, in the present embodiment, the tube 20 of the infusion set attached to the infusion stand 21 contacts the left and right side plates 9 but does not contact the lower leg receiving portion 6. Therefore, the tube 20 does not get caught in the lower leg receiving portion 6 during the process in which the seated person moves the infusion stand 21 forward while the lower leg receiving portion 6 is tilted and stored in the storage position.

As described above, according to the chair device 1 of the present embodiment, it is easy for a seated person to stand up from the chair device 1 and move forward. Further, according to the chair apparatus 1 of the present embodiment, the tube 20 of the infusion set does not get caught on the lower leg receiving portion 6 in the process of the occupant moving to the front of the chair apparatus 1, so that the needle during the infusion is intended. It is difficult for problems such as slipping out without occurring.

Further, since the front side portions 9b of the left and right side plates 9 of the chair device 1 of the present embodiment are inclined forward so as to go forward as they go upward, the infusion stand 21 should not hit the upper portions of the left and right side plates 9. When the infusion stand 21 is moved, the legs of the infusion stand 21 are less likely to collide with the chair device 1 even when the infusion stand 21 is pulled toward the seated person.

Although the embodiment of the present invention has been described in detail above with reference to the drawings, the specific configuration is not limited to this embodiment, and includes design changes and the like within a range not departing from the gist of the present invention.
For example, the chair device 1 may have a table that can be stored or moved.
