Description

治療台
　本発明は、治療台に関し、より詳しくは、患者の腰部の手技療法に好適に使用される治療台に関する。
に関する。
　カイロプラクティック療法に用いられる従来の治療台として、特許文献１に開示されているトムソンテーブルが知られている（例えば特許文献１）。トムソンテーブルは、横たわった患者の顔、胸、腰および脚に対応する部分がそれぞれ分割されており、胸や腰等に対応する部分が個別に上下動可能なドロップ部とされている。この構成によれば、いずれかのドロップ部を持ち上げた状態で、患者の治療部位を瞬間的に圧迫することにより、当該ドロップ部を落下させて治療を行うことができる。
米国特許第２９２６６６０号
　腰痛の原因としては、骨盤の左右を支持する一対の仙腸関節のずれが主な要素として考えられている。人体の重心は骨盤内に存在しており、一対の仙腸関節にずれが生じると、人体の重心線が本来の中心軸から外れるために、全身にひずみが生じるおそれがある。このため、腰痛治療においては仙腸関節のずれを矯正することが有効である。
　ところが、上記従来の治療台は、患者の腰を支持する部分が一体的に落下するため、一対の仙腸関節は、その周縁部も含めて同時に落下することになり、十分な矯正が困難であった。
　そこで、本発明は、安価な構成により腰痛治療を効果的に行うことができる治療台の提供を目的とする。
　本発明の前記目的は、患者が横たわった状態で胸部および脚部をそれぞれ支持する胸部支持部と脚部支持部との間に、腰部を支持する腰部支持部を備える治療台であって、前記腰部支持部は、患者の体軸方向および体幅方向にそれぞれ分割された複数の分割部材と、前記分割部材を個別に上下動可能に支持する支持体とを備える治療台により達成される。
　この治療台において、前記支持体は、前記分割部材を上昇させるリフト手段と、上昇した前記分割部材を所定の落下高さに保持する保持手段とを備え、前記保持手段は、弾性部材の付勢力により前記分割部材に係合する係合片を備えることが好ましく、前記分割部材に上方からの衝撃力が作用すると、前記係合片と前記分割部材との係合が解除されて前記分割部材が落下するように構成することができる。前記保持手段は、前記分割部材の落下高さを複数から選択可能に構成されていることが好ましい。
　本発明によれば、安価な構成により腰痛治療を効果的に行うことができる治療台を提供することができる。
本発明の一実施形態に係る治療台の平面図である。 図１のＡ－Ａ断面図である。 図２の要部拡大断面図である。 本発明の一実施形態に係る治療台の作動を説明するための要部拡大断面図である。
　以下、本発明の実施の形態について、添付図面を参照して説明する。図１は、本発明の一実施形態に係る治療台の平面図である。図１に示すように、治療台１は、筐体状に形成された台本体１０の天板１１の上方に患者が横たわった状態で、患者の頭部、胸部、腰部および脚部をそれぞれ支持する頭部支持部２、胸部支持部３、腰部支持部２０および脚部支持部４を備えている。頭部支持部２、胸部支持部３、腰部支持部２０および脚部支持部４は、クッション材（図示せず）などにより被覆することが好ましい。
　腰部支持部２０は、患者の体軸方向（起立状態での上下方向）および体幅方向（起立状態での左右方向）にそれぞれ分割されてマトリクス状に配置された平面視矩形状の４つの分割部材２１を備えている。分割部材２１は、体軸方向および体幅方向の双方に分割されていれば、その個数は特に限定されない。また、各分割部材２１は、患者の腰部を全体で支持できるように配置されていればよく、マトリクス状以外に、千鳥状など他の配置であってもよい。
　図２は、図１のＡ－Ａ断面図である。図２に示すように、複数の分割部材２１は、天板１１に形成された貫通孔１１ａから上部が突出するように、支持体３０に支持されている。支持体３０は、複数の分割部材２１を個別に上下動可能に支持する複数のリフト装置３１と、各リフト装置３１により上昇した分割部材２１をそれぞれ所定高さの保持位置に保持する保持機構４０とを備えている。リフト装置３１および保持機構４０は、台本体１０の内部に水平に配置された２つの台板１２，１３にそれぞれ支持されている。
　リフト装置３１は、エアシリンダ等の流体圧シリンダから構成されており、ロッド３１ａの上端が分割部材２１の下面に接離可能に当接する。リフト装置３１は、ジャッキやチェーンブロックなど、分割部材２１を上昇可能な他の装置であってもよく、その駆動方式は、手動式の他、油圧式や電動式などにより自動式にすることも可能である。分割部材２１には段部２１ａが形成されており、段部２１ａが天板１１の貫通孔１１ａの周縁部に当接することにより、リフト装置３１の作動による分割部材２１の過度の上昇が規制される。
　図３は、図２に示す分割部材２１の一方を拡大した断面図である。図３に示すように、保持機構４０は、支持体３０の縁部が摺動するように台板１３から起立する起立壁４１と、起立壁４１に形成された収容部４１ａに収容された係合片４２とを備えている。
　係合片４２は、断面円弧状の先端部が、バネ等からなる弾性部材４３の付勢力により水平方向に突出するように配置されて、分割部材２１の側壁に形成された断面円弧状の係合凹部２１ｂと係合することにより、分割部材２１を保持することができる。分割部材２１に対する係合片４２の押圧力は、調整ねじ４４の進退により適宜調整することができる。係合片４２を弾性部材４３の付勢力により分割部材２１に係合する具体的な構成は特に限定されるものではなく、例えば、市販のインデックスプランジャを使用してもよい。
　係合片４２は、本実施形態では分割部材２１の矩形状の各辺に対応してそれぞれ設けられているが、分割部材２１を保持可能な配置であればよく、例えば、分割部材２１の互いに対向する縁部と係合するように一または複数の係合片４２を配置してもよい。
　分割部材２１の係合凹部２１ｂは、高さ方向に沿って複数形成されており、係合片４２が係合する係合凹部２１ｂを選択することにより、高さを変えて分割部材２１を保持することができる。係合片４２は、必ずしも係合凹部２１ｂに係合する必要はなく、例えば、分割部材２１の下面や突起部などと係合する構成であってもよい。
　上記の構成を備える治療台１によれば、患者が横たわった状態で、図３に示すように、リフト装置のロッド３１ａにより分割部材２１を下方から持ち上げた状態から、図４（ａ）に示すようにロッド３１ａを降下させることにより、係合片４２をいずれかの係合凹部２１ｂに係合させて、分割部材２１を所定の高さに保持することができる。この後、患者の腰部を瞬間的に圧迫して、分割部材２１に下方への衝撃力が作用すると、図４（ｂ）に示すように、係合片４２が弾性部材４３の付勢力に抗して移動し、係合片４２と分割部材２１との係合が解除されて分割部材２１が台板１３に落下する。こうして、患者を圧迫する力、および分割部材２１の落下高さに応じた力を、患者の腰部に作用させることができる。
　本実施形態の治療台１は、胸部支持部３と脚部支持部４との間に配置されて患者の腰部を支持する腰部支持部２０が、患者の体軸方向および体幅方向にそれぞれ分割された分割部材２１を備えており、各分割部材２１が個別に上下動可能に支持されているため、患者の腰部に作用する衝撃力が、従来のように、体軸方向の各位置において上下方向（体厚方向）に二次元的に作用するのではなく、これに体幅方向を加えた三次元的に作用する。したがって、落下させる分割部材２１を、体軸方向および体幅方向の双方で適宜選択することにより、治療のバリエーションを高めて、左右の仙腸関節のずれ等を効果的に矯正することができる。
　また、本実施形態のように、係合片４２を係合させる係合凹部２１ｂを高さ方向に複数形成する等して、各分割部材２１の落下高さを選択可能に構成することにより、各分割部材２１の落下に伴う衝撃力を個別に設定することができるので、所望の治療をより容易に行うことができる。分割部材２１の落下高さの設定は、図４（ａ）に示すロッド３１ａを台板１３の上方に突出させた状態に保持し、このロッド３１ａの突出高さを調整して行うことも可能であり、あるいは、これを複数の係合凹部２１ｂの選択と併用してもよい。分割部材２１の落下高さは特に制限されないが、約１０ｍｍ～３０ｍｍの範囲に設定することが可能であり、例えば、落下高さを２段階に設定する場合には、１５ｍｍおよび３０ｍｍのいずれかを選択可能に構成することが好ましい。
　頭部支持部２、胸部支持部３および脚部支持部４についても、腰部支持部２０と同様に、患者の体軸方向および体幅方向にそれぞれ分割されて個別に上下動可能な複数の分割部材を備える構成にすることもできる。
