PROBLEM TO BE SOLVED: To flexibly deal with individual needs of dentists and to improve variability of a device so that different needs of different dental treatment rooms are satisfied.SOLUTION: In an integrated dental treatment device having a chair for a patient and a dental treatment unit, there are structurally connected to the dental treatment unit a spittoon structure, various arms, arbitrary devices or connector structures of tools and the like. There are also included in the treatment device, a means for installing the dental treatment unit on the floor and a means for structurally connecting to the dental treatment unit for the purpose of supporting the chair for a patient. The dental treatment unit is capable of turning around a vertical axis and is at least symmetrical about external parts, forming at least one vertical symmetrical plane. An axis as a standard of the turnable arrangement of the arms for an assistants tools/dentists tools is at least integrated with the symmetrical plane. The chair for a patient is at least symmetrical about the external parts, forming at least one vertical symmetrical plane, where the axis as the standard of the turnable arrangement of the dental treatment unit is integrated with the symmetrical plane.COPYRIGHT: (C)2014,JPO&INPIT【課題】歯科医の個人的ニーズに柔軟に対応し、異なる歯科処置室の異なるニーズを満たすように装置の可変性を向上させる。【解決手段】患者用椅子及び歯科治療ユニットを備える統合歯科治療装置は、歯科治療ユニットに、スピットン構成体、種々のアーム、任意のデバイス又は道具用のコネクタ構造等が構造的に接続され、歯科治療ユニットを床に据え付ける手段及び患者用椅子を支持するための歯科治療ユニットに構造的に接続する手段を備え、歯科治療ユニットは垂直軸の回りで回動可能であり、少なくとも外部部分に関し対称で少なくとも1つの垂直対称面を形成し、少なくとも助手の器具/歯科医の器具用のアームの回動可能な配置の基準となる軸が対称面と一体化され、患者用椅子は、少なくともその外部部分に対称で少なくとも1つの垂直対称面を形成し、歯科治療ユニットの回動可能な配置の基準となる軸が対称面と一体化する。【選択図】 図6
