【発明の属する技術分野】
本発明は、車椅子に乗った患者が、歯科治療椅子へ乗降する際に使用して、患者の歯科治療椅子への乗降を助けるようにした歯科治療椅子への乗降補助装置に関する。
【0002】
【従来の技術】
図2は、歯科治療椅子に、車椅子に乗った患者を乗降させる場合の例を説明するための要部構成図で、図中、10は歯科治療椅子、20は車椅子で、車椅子20に乗っている患者Aを、歯科治療椅子10に乗せる場合、介添人Bは、歯科治療椅子10のバックレスト11の後側に立ち、バックレスト11の横側から患者Aの脇をかかえ、介添人Cが患者Aの膝を持って、患者Aを介添人BとCで一緒に持ち上げ、歯科治療椅子10のコンターシートの上に横方向から乗せる場合が多かった。
【0003】
しかし、実際には、車椅子に乗った患者でも、自力で立つこともでき、多少は歩くことのできる人もおり、このような人は、できるだけ自力で乗降するのが好ましいが、中には、何らかの手助けが必要な人もいる。
【0004】
【発明が解決しようとする課題】
本発明は、上述のごとき実情に鑑みてなされたもので、車椅子上の患者を歯科治療椅子に容易に乗せ、或いは、歯科治療椅子上の患者を車椅子へ容易に乗せることができるようにした歯科治療椅子乗降用の補助装置に関する。
【0005】
【課題を解決するための手段】
請求項1の発明は、歯科治療椅子の前に配置し、車椅子の患者が前記歯科治療椅子に乗降するのを介助する補助装置であって、該補助装置は、患者が乗るための回転板と、該回転板上に所定の間隔をおいて平行に相対向して立設された一対の肘受けアームを有し、該肘受けアームは、下端部においてピン軸により回動可能に支持されており、肘受け、前記肘受けアームの上端部において、平行状態を保って前後に移動可能であることを特徴としたものである。
【0006】
請求項2の発明は、請求項1の発明において、前記肘受けアームは伸縮自在であることを特徴としたものである。
【0007】
請求項3の発明は、請求項1又は2の発明において、前記肘受けアームは予め設定されたプログラムに基いて回動し、該回動に対応して長さが調整されることを特徴としたものである。
【0008】
【発明の実施の形態】
図1は、本発明による歯科治療椅子へ乗降補助装置の一実施例を説明するための図で、図中、10は歯科治療椅子、20は車椅子、30は本発明による乗降補助装置で、該乗降補助装置は可搬式に構成されており、使用時、つまり、車椅子に乗った患者が来た時は、術者又はアシスタントは、図示のように、該乗降補助装置30を歯科治療椅子10の前に持ってくる。この状態で、車椅子20を乗降補助装置30の前に運び、患者は、一旦、該乗降補助装置30に移動する。
【0009】
乗降補助装置30について説明すると、該乗降補助装置30は、例えば、キャスタ31を有する基板32の上に、回転板33を有し、該回転板33には、所定の間隔(人間が入れる間隔)をおいて一対の肘受けアーム35 1 , 35 2 が立設されている。これら肘受けアーム35 1 , 35 2 の下端はピン軸36を中心に前後(矢印X方向)に回動可能に取り付けられており、上端には肘受け34 1 , 34 2 が肘受けアーム35 1 , 35 2 の回動にかかわりなく平行状態を保つように取り付けられている。
【0010】
車椅子に座った患者の歯科治療をするには、まず、本発明による乗降補助装置30を歯科治療椅子10の前に配置し、次いで、該乗降補助装置30の前に車椅子20を運んできて、該車椅子20の乗降方向と乗降補助装置の乗降方向が一致するように、回転板33を回転し(矢印Y方向)、次いで、肘受け341,342を車椅子20に向けて、つまり、歯科治療椅子10より前方に回動し(矢印X方向)図1のA1の位置にする。この状態で、患者は車椅子20から降りるが、その際、肘受け341,342の助けをかりて回転板33の上に乗ることができる。つまり、患者は、手前に伸長してきた肘受け341,342に掴まり、その後、肘受け341,342を歯科治療椅子10に向って回動し、図1のA2の位置にすると、患者は、該肘受け341,342の回動に案内されて回転板33の上に立つことができる。
【0011】
次いで、つまり、肘受けをA2の位置にした状態で回転板33を回転させ、患者の背中が歯科治療椅子10に対向した状態にして、換言すれば、患者が歯科治療椅子10に着座できる状態にし、次いで、肘受け341,342を歯科治療椅子10に向けて回転し、図1のA3の位置にすると、患者は、そのまま歯科治療椅子10に腰掛けることができ、歯科治療を受けることができる。歯科治療中、乗降補助装置30は、歯科治療の邪魔にならないように、片付けておく。
【0012】
歯科治療が終わった後は、前記と逆の経路を辿って車椅子20に戻る。つまり、本発明による乗降補助装置30を歯科治療椅子10の前に持って来て、肘受けの向きを、歯科治療椅子の向きに合せ、肘受けを患者に向けて倒す。その状態で、患者が肘受けに掴まると、肘受けが上昇しながら歯科治療椅子に向って回動し、患者は、この肘受けの動きに案内されて回転板33の上に乗ることができる。この状態で、回転板を回転して身体の向きを逆にして、つまり、背中を車椅子に向けた状態にし、この状態で、肘受けを車椅子に向けて倒すと、患者は、肘受けに案内されて車椅子に腰掛けることができる。
【0013】
なお、以上には、患者が車椅子から歯科治療椅子へ乗る時の手順及び歯科治療椅子から車椅子に戻る時の手順の一例を示したが、本発明は、上記例に限定されるものではなく、患者の状態に応じて、任意所望の仕方で、本発明による乗降補助装置を利用して乗降することができる。
【0014】
また、図には示さないが、前記回転板33の回転、肘受け341,342の回動はモータにより電気的に行なわれるものであり、その操作は、肘受け341,342或いは肘受けアーム351,352に設けた操作スイッチにより術者又はアシスタント、或いは、患者自身によって行うようにしてもよい。
【0015】
或いは、肘受けアーム351,352を伸縮自在(矢印Z方向)に構成しておき、操作スイッチにより患者の身長等に合せて伸縮できるようにしておけば、より安全にかつ効率的に車椅子上の患者を歯科治療椅子に案内し、或いは、歯科治療椅子上の患者を車椅子に戻すことができる。
【0016】
更には、肘受けアーム351,352の伸縮を該肘受けアームの回動に応じて制御するように、予めプログラムしておけば、A2の直立時の高さを変えることなく、A1の位置をより患者に近づけることができ、患者の乗降をより楽にすることができる。
【0017】
【発明の効果】
以上の説明から明らかなように、本発明によると、車椅子上の患者を多くの人の介添えを要することなく、容易かつ安全に歯科治療椅子に案内し、かつ、歯科治療椅子上の患者を車椅子に戻すことができる。

The patient can stand on the rotating plate 33 while being guided by the rotation of the elbow receivers 34 1 and 34 2 .
[0011]
That is, in other words, the rotating plate 33 is rotated with the elbow rest at the position A 2 so that the patient's back faces the dental treatment chair 10, in other words, the patient can sit on the dental treatment chair 10. Then, when the elbow receivers 34 1 and 34 2 are rotated toward the dental treatment chair 10 to the position A 3 in FIG. 1, the patient can sit on the dental treatment chair 10 as it is, and dental treatment is performed. Can receive. During the dental treatment, the entry / exit assistance device 30 is put away so as not to interfere with the dental treatment.
[0012]
After the dental treatment is finished, the route returns to the wheelchair 20 following the reverse route. That is, the boarding / alighting assisting device 30 according to the present invention is brought in front of the dental treatment chair 10, the direction of the elbow support is adjusted to the direction of the dental treatment chair, and the elbow support is tilted toward the patient. In this state, when the patient grasps the elbow rest, the elbow rest rises and rotates toward the dental treatment chair, and the patient can get on the rotating plate 33 while being guided by the movement of the elbow rest. it can. In this state, rotate the rotating plate to reverse the direction of the body, that is, with the back facing the wheelchair, and in this state, tilt the elbow rest toward the wheelchair and the patient will be guided to the elbow rest. You can sit in a wheelchair.
[0013]
In addition, although an example of the procedure when the patient gets on the dental treatment chair from the wheelchair and the procedure when the patient returns from the dental treatment chair to the wheelchair is shown above, the present invention is not limited to the above example, Depending on the condition of the patient, it is possible to get on and off using the boarding assistance device according to the present invention in any desired manner.
[0014]
Although not shown in the figure, the rotation of the rotating plate 33 and the rotation of the elbow receivers 34 1 and 34 2 are electrically performed by a motor, and the operation is performed by the elbow receivers 34 1 and 34 2 or The operation may be performed by an operator, an assistant, or the patient himself / herself by operating switches provided on the elbow support arms 35 1 and 35 2 .
[0015]
Alternatively, if the elbow support arms 35 1 and 35 2 are configured to be telescopic (in the direction of the arrow Z) and can be expanded and contracted according to the height of the patient by an operation switch, the wheelchair is safer and more efficient. The upper patient can be guided to the dental chair or the patient on the dental chair can be returned to the wheelchair.
[0016]
Furthermore, if it is programmed in advance so that the expansion and contraction of the elbow support arms 35 1 and 35 2 is controlled in accordance with the rotation of the elbow support arms, the height of A 2 in the upright position is not changed. The position of 1 can be brought closer to the patient, and the patient can get on and off more easily.
[0017]
【The invention's effect】
As is clear from the above description, according to the present invention, the patient on the wheelchair can be easily and safely guided to the dental treatment chair without requiring many people, and the patient on the dental treatment chair can be guided to the wheelchair. Can be returned to.
