The set stop position can be set according to the height of the patient. For example, the set stop position when the height is 1500 mm is 150 mm, and the set stop position when the height is 1600 mm is set by an input means (not shown). When the height is 200 mm and the height is 1700 mm, the set stop position is divided into three stages, such as 250 mm, and the stop position of the pad portion is determined by selecting a switch (input means) of the set stop position suitable for the patient's height. be able to. In addition, by changing the speed of the stepping motor and slowing up and down the pad portion, standing can be assisted at a speed suited to the patient. In addition to the strain gauge, the load detecting means is not limited to the above as long as it can detect the strain of the pad support portion.
図７は、前記起立および着座補助装置２および前記歯科治療椅子１の起立補助フローチャートである。
ステップＳ１において、前記パッド部８が該歯科治療椅子１に着座している患者３の前方の所定位置に配置されたかを前記回転機構部１２に設けたロック機構部にあるリミットスイッチからの信号によって判定し、患者３前方の所定位置にあると判定された場合はステップＳ２に移行する。ステップＳ２において、前記荷重検知手段からの荷重がある閾値以上加わっているか否かを判定する。この判定において、１０Kg以上の荷重が加わったと判定された場合、ステップＳ３に移行し、１０Kg以上の荷重が一定時間である３秒以上連続で検知された場合、該パッド部８に患者３の体重が加わり、患者３が起立動作を行う準備ができたと判定され、ステップＳ４において該歯科治療椅子１の昇降部１８と該パッド部８との上昇駆動を指示する。さらにステップＳ５において図示しない入力手段にて入力された設定停止位置に到達したかを判定し、該設定停止位置に到達した場合、該歯科治療椅子１の昇降部１８および該パッド部８の停止を指示する。なお、ステップＳ１において、該パッド部８が患者３の前方の所定位置にない場合、またはステップＳ２において、設定荷重である１０Kg以上に満たない場合、またはステップＳ３において、荷重が１０Kg以上を満たしていても３秒以上連続で荷重を検知できない場合、ステップＳ５において、該歯科治療椅子１の昇降部１８と該パッド部８とが設定停止位置まで到達していない場合にはステップＳ１に移行し上記の処理を繰り返す。
FIG. 7 is a flowchart of standing assistance for the standing and sitting assistance device 2 and the dental treatment chair 1.
In step S <b> 1, whether or not the pad portion 8 is disposed at a predetermined position in front of the patient 3 sitting on the dental treatment chair 1 is determined by a signal from a limit switch in a lock mechanism portion provided in the rotation mechanism portion 12. If it is determined and it is determined that the patient 3 is in a predetermined position in front of the patient 3, the process proceeds to step S2. In step S <b> 2, it is determined whether or not the load from the load detection means is applied beyond a certain threshold. In this determination, if it is determined that a load of 10 kg or more is applied, the process proceeds to step S3. If a load of 10 kg or more is detected continuously for 3 seconds or more which is a fixed time, the weight of the patient 3 is placed on the pad portion 8. Is added, and it is determined that the patient 3 is ready to perform the standing motion, and in step S4, the elevating unit 18 of the dental treatment chair 1 and the pad unit 8 are instructed to be driven up. Further, in step S5, it is determined whether or not a set stop position input by an input means (not shown) has been reached. When the set stop position is reached, the lifting and lowering portions 18 and 8 of the dental treatment chair 1 are stopped. Instruct. In step S1, if the pad portion 8 is not at a predetermined position in front of the patient 3, or if the set load is less than 10 kg or more in step S2, or if the load satisfies 10 kg or more in step S3. If the load cannot be detected continuously for 3 seconds or more, in step S5, if the elevating part 18 and the pad part 8 of the dental treatment chair 1 have not reached the set stop position, the process proceeds to step S1 and the above-described process is performed. Repeat the process.
以上のように、患者３が起立動作を行う際に確実に前記パッド部８に力が加わったかを判定したうえで歯科治療椅子１の昇降部１８の上昇と連動させて、該パッド部８を斜め上方に移動させ、設定停止位置で停止するようにしている。
また、該荷重検知手段を設けることで、起立および着座補助装置２の上昇中に患者３がパッド部８からずり落ちた場合、一定荷重を満たさないと判定され、歯科治療椅子１の昇降部18と起立および着座補助装置２の上昇を止めることが可能となり、起立による転倒等の事故防止にも役立つ。さらに患者３を起立させたあとの退出は該歯科治療椅子１の側方から行えるほか、該パッド部８を９０度回転させることで、該歯科治療椅子１前方からの退出も行えるよう構成されており、患者の退出を妨げないようにしている。
なお、本実施例では日本人の標準的な体型から該パッド部８に加わる圧力値を１０Kg以上、加わった体重が一定時間以上連続して検知するための時間を３秒以上としたが、これに限定されることはなく、患者個人にあわせて値を設定することも可能である。
また、設定停止位置の設定も本実施例に限定されることなく、任意の設定停止位置を入力することも可能である。
さらに、本実施例では患者の起立動作補助を自動により行ったが、術者やアシスタントが図示しないスイッチを押すことによる手動での駆動も可能である。
