以下、本発明に係る人工透析用治療椅子の一実施例を図面と共に説明する。
図において、１は湾曲した一対の脚杆１ａを連結棒１ｂで連結した脚体にして、各脚杆１ａの両端には固定手段を有するキャスター１ｃが取付けられている。また、脚杆１ａにおける前方のキャスター１ｃが取付けられている部分にはストッパー１ｄが取付けられ、該ストッパー１ｄを浮き上げた状態とすることで椅子の移動が可能なように構成されている。さらに、前記脚体１における脚杆１ａの間には後述する座部２および後述するリンク機構や油圧シリンダ等のアクチュエータを取付けるための取付部材３が取付けられている。 Hereinafter, an embodiment of a treatment chair for artificial dialysis according to the present invention will be described with reference to the drawings.
In the figure, reference numeral 1 denotes a leg body in which a pair of curved leg rods 1a are connected by a connecting rod 1b, and casters 1c having fixing means are attached to both ends of each leg rod 1a. Further, a stopper 1d is attached to a portion of the leg rod 1a to which the front caster 1c is attached, and the chair can be moved by raising the stopper 1d. Further, between the leg rods 1a of the leg 1, a seat 2 described later and a mounting member 3 for mounting an actuator such as a link mechanism and a hydraulic cylinder described later are mounted.

前記座部２は後部座部２ａと前部座部２ｂとから構成され、後部座部２ａは前記取付部材３に固定され、前部座部２ｂの後方は取付部材３に回動自在に対して回動自在に軸支点ａで軸支されている。前記脚体１の脚杆１ａには背凭れ支持板５の下端が立設固定され、該背凭れ支持板５の上端の軸支点ｂで背凭れ４から延長されている延長片４ａが回動自在に軸支されている。   The seat 2 is composed of a rear seat 2a and a front seat 2b. The rear seat 2a is fixed to the mounting member 3, and the rear of the front seat 2b is pivotable to the mounting member 3. And is pivotally supported by a pivot point a. The lower end of the backrest support plate 5 is erected and fixed to the legrest 1a of the leg 1 and an extension piece 4a extended from the backrest 4 at the pivot point b at the upper end of the backrest support plate 5 is rotated. It is supported freely.

前記脚体１の脚杆１ａの前方どうしを接続する前記連結棒１ｂには油圧シリンダ等の背凭れ用アクチュエータ６のシリンダ側が軸支され、該アクチュエータ６のピストン側は前記背凭れ４の背凭れ基板下端延長部４ｂが軸支されている。また、前記背凭れ用アクチュエータ６と背凭れ基板下端４ｂとの軸支点ｃ（図４参照）には背凭れリンク７の一端が軸支されている。   A cylinder side of a backrest actuator 6 such as a hydraulic cylinder is pivotally supported on the connecting rod 1b that connects the front ends of the leg rods 1a of the leg body 1. The piston side of the actuator 6 is the backrest of the backrest 4. A substrate lower end extension 4b is pivotally supported. Further, one end of a backrest link 7 is pivotally supported at a pivot point c (see FIG. 4) between the backrest actuator 6 and the backrest substrate lower end 4b.

この背凭れリンク７の他端は「くの字」状の連結リンク８の一端に軸支点ｄで軸支され、該連結リンク８の他端は一端が前記連結棒１ｂに下端が固定された固定リンク９の先端に軸支点ｅで軸支されている。また、連結リンク８の中央屈曲部は一端が前記前部座部２ｂの裏面に一端か軸支点ｆで軸支された座部リンク１０に軸支されている。   The other end of the backrest link 7 is pivotally supported at one end of a "U" -shaped connecting link 8 by a pivot point d, and the other end of the connecting link 8 is fixed at the lower end to the connecting rod 1b. The fixed link 9 is pivotally supported at the tip end by a pivot point e. Further, one end of the central bent portion of the connecting link 8 is pivotally supported by a seat link 10 that is pivotally supported at one end or a pivot point f on the back surface of the front seat 2b.

前記背凭れ４の背凭れ基板にはベース形状に形成された肘掛け基板１１ａが回動自在に軸支され、該肘掛け基板１１ａに肘掛け１１が固定されている。また、肘掛け基板１１ａには肘掛けリンク１２の上端が取付けられており、該肘掛けリンク１２の下端は一端が前記背凭れ支持板５に軸支された連結リンク１３の他端が軸支されている。なお、４ｃは取り外し自在な枕である。   An armrest substrate 11a formed in a base shape is rotatably supported on the backrest substrate of the backrest 4, and the armrest 11 is fixed to the armrest substrate 11a. Further, the upper end of the armrest link 12 is attached to the armrest substrate 11a, and the lower end of the armrest link 12 is pivotally supported at the other end of the connecting link 13 pivotally supported by the backrest support plate 5. . 4c is a removable pillow.

このように構成されたリンク機構の動作を図１〜図６と共に説明する。
図１、図２は患者を導入する状態を示し背凭れ４が起立位置にあり、また、座部２の後部座部２ａと前部座部２ｂとが略水平状態となっている。なお、後に詳述する前垂れ１４は略起立状態となっており、かつ、ステップ１５は床面に接する位置となっている。 The operation of the link mechanism configured as described above will be described with reference to FIGS.
1 and 2 show a state in which a patient is introduced. The backrest 4 is in an upright position, and the rear seat 2a and the front seat 2b of the seat 2 are substantially horizontal. In addition, the front sag 14 described in detail later is in a substantially upright state, and the step 15 is in a position in contact with the floor surface.

この状態において患者を椅子に着座させた後に背凭れ用アクチュエータ６内を収縮させると軸支点ｃが右方向に引かれるので、背凭れ４は軸支点ｂを回動支点として伏倒方向に変位する。一方、軸支点ｃが右方向に移動することで背凭れリンク７が右方向に移動して連結リンク８を軸支点ｅを支点として時計方向に回転させる。   In this state, when the backrest actuator 6 is contracted after the patient is seated on the chair, the shaft fulcrum c is pulled in the right direction, so that the backrest 4 is displaced in the prone direction with the shaft fulcrum b as the rotation fulcrum. . On the other hand, when the shaft fulcrum c moves in the right direction, the backrest link 7 moves in the right direction, and the connecting link 8 is rotated clockwise around the shaft fulcrum e.

該連結リンク８が時計方向に回動されると連結リンク８の中央折曲部に軸支されている座部リンク１０が押し上げられるので、軸支点ｆで軸支されている前部座部２ｂの前方側が押し上げ（以下、チルト動作という）られる（図３，４参照）。従って、前部座部２ｂがチルト動作することにより着座している患者は前方にずれて移動するのを防止するため、患者の姿勢が安定した状態で寝動作に移行することとなる。   When the connecting link 8 is rotated in the clockwise direction, the seat link 10 that is pivotally supported by the central bent portion of the connecting link 8 is pushed up, so that the front seat 2b that is pivotally supported at the pivot point f. Is pushed up (hereinafter referred to as tilting operation) (see FIGS. 3 and 4). Therefore, the patient sitting due to the tilting operation of the front seat 2b is prevented from moving forward and shifted to the sleeping operation with the patient in a stable posture.

そして、さらに背凭れ用アクチュエータ６のピストンが収縮して背凭れ４が伏倒し、該伏倒動作が全寝角度の中間地点になると座部リンク１０は床面に対して略垂直状態となって前部椅子２ａを最大限にチルト状態（例えば、後部座部２ａに対して１５度の角度で前部座部２ｂの前方が高くなる）とする。従って、背凭れ４の伏倒に伴う変位に対して患者の前方への移動が防止され安定した姿勢で仰臥状態に移行できる。   Further, when the piston of the backrest actuator 6 contracts and the backrest 4 falls down, and the overturning operation becomes an intermediate point of the total sleeping angle, the seat link 10 is in a substantially vertical state with respect to the floor surface. The front chair 2a is in a fully tilted state (for example, the front of the front seat 2b is raised at an angle of 15 degrees with respect to the rear seat 2a). Therefore, the patient can be prevented from moving forward with respect to the displacement accompanying the lying of the backrest 4 and can shift to the supine state in a stable posture.

さらに、背凭れ用アクチュエータ６のピストンが収縮され背凭れリンク７が右方向に移動すると連結リンク８がさらに時計方向に回転されるので、座部リンク１０は垂直方向から反時計方向に回転する。すなわち、座部リンク１０と前部座部２ａとの軸支点が下降するために後部座部２ａと前部座部２ａとはフラットな状態となり、従って、患者はベッドに伏倒した状態と同じ姿勢となり４時間にもおよぶ人工透析を安楽に受けることができることとなる。   Further, when the piston of the backrest actuator 6 is contracted and the backrest link 7 moves to the right, the connecting link 8 is further rotated in the clockwise direction, so that the seat link 10 is rotated in the counterclockwise direction from the vertical direction. That is, since the pivot point of the seat link 10 and the front seat 2a is lowered, the rear seat 2a and the front seat 2a are in a flat state. You will be in a posture and you can comfortably receive 4 hours of artificial dialysis.

なお、前記背凭れ４の伏倒時において、肘掛け１１が取付けられている肘掛け基板１１ａは肘掛けリンク１２および連結リンク１３を介して固定状態を維持している背凭れ支持板５に連結されているので、背凭れ４と共に下降するが肘掛け１１は常に水平状態を維持するので、患者が肘を肘掛け１１に預けた姿勢であっても腕に負担を掛けることがない。   In addition, when the backrest 4 is lying down, the armrest substrate 11a to which the armrest 11 is attached is connected to the backrest support plate 5 that maintains a fixed state via the armrest link 12 and the connection link 13. Therefore, although it descends with the backrest 4, the armrest 11 always maintains a horizontal state, so that even if the patient puts his elbow on the armrest 11, the arm is not burdened.

次に、前垂れ１４、ステップ１５について説明する。
前垂れ１４の前垂れ基板１４ａは前垂れリンク１６に取付けられており、該前垂れリンクの上端は前記取付部材３の上部に軸支点ｇによって軸支されている。また、前垂れ基板１４ａには油圧シリンダ等の前垂れアクチュエータ１７のピストン側が軸支され、シリンダ側は取付部材３に軸支されている。さらに、前垂れリンク１６の先端にはステップ１５のステップ基板１５ａの後方部が軸支点ｈによって軸支さている。さらに、ステップ基板１５ａには一端が取付部材３に軸支点ｉに軸支された平行リンク１８の他端が軸支点ｊに軸支されている。 Next, the front droop 14 and step 15 will be described.
The front hanging board 14 a of the front hanging 14 is attached to the front hanging link 16, and the upper end of the front hanging link is pivotally supported on the upper portion of the mounting member 3 by a pivot fulcrum g. Further, the piston side of the front drooping actuator 17 such as a hydraulic cylinder is pivotally supported on the front drooping board 14 a, and the cylinder side is pivotally supported by the mounting member 3. Further, the rear portion of the step board 15a of the step 15 is pivotally supported by the shaft fulcrum h at the front end of the front hanging link 16. Further, the other end of the parallel link 18 whose one end is pivotally supported by the mounting member 3 at the pivot fulcrum i is pivotally supported at the pivot fulcrum j by the step board 15a.

なお、１９はステップ基板１５ａの裏面に取付けられたストッパーにして、ステップ１５が床面側に位置し患者がステップ１５に乗って着座する時にガタつかないようにするためのものである。   Reference numeral 19 denotes a stopper attached to the back surface of the step board 15a so that the step 15 is located on the floor surface side, and the patient does not rattle when sitting on the step 15.

このように構成された前垂れ１４の動作を説明するに、前記した背凭れ４および座部２がフラットな状態となった位置において前垂れ用アクチュエータ１７を伸長すると、前垂れ基板１４ａが前垂れ用アクチュエータ１７のピストンによって水平方向に押し上げられる。   In order to explain the operation of the front sag 14 configured as described above, when the front sag actuator 17 is extended at a position where the backrest 4 and the seat 2 are in a flat state, the front sag substrate 14 a It is pushed up horizontally by the piston.

この押し上げ時において、ステップ１５は前垂れリンク１６と平行リンク１８とによって前垂れ１４の水平方向の変位に伴って水平状態を維持しながら上昇する。そして、前垂れ１４、ステップ１５、背凭れ４および座部２と水平状態となった位置で前垂れ用アクチュエータ１７を停止すると椅子全体はベッド状態となる（図７、図８参照）。従って、この椅子に乗っている患者は安定した仰臥状態で人工透析を受けることができる。   At the time of the push-up, step 15 is lifted while maintaining the horizontal state by the horizontal displacement of the front droop 14 by the front droop link 16 and the parallel link 18. Then, when the front suspension actuator 17 is stopped at a position that is in a horizontal state with the front suspension 14, the step 15, the backrest 4, and the seat 2, the entire chair is in a bed state (see FIGS. 7 and 8). Therefore, the patient on this chair can receive artificial dialysis in a stable supine state.
