【発明の属する技術分野】
本装置は、歯科用チェアユニットにおけるインスツルメント水回路の滅菌及び腐食の防止に係り、特にインスツルメントをホルダにセットしたまま実施できる歯科治療装置に関する。
【０００２】
【従来の技術】
従来、水回路内の水処理装置は、水回路内の排出及び吸引のチューブ接続端を集約して水処理ユニットにセットし、該ユニットから排出される殺菌水並びに水を吸引排水して、水回路の滅菌並びに腐食、劣化の防止を行う機構のものがあった。また、コップ給水及びスピットン洗浄用の水回路は、単に水を流して洗浄していた。
【０００３】
【発明が解決しようとする課題】
しかしながら、上記の機構においては、
殺菌水と洗浄水との切換制御部の外に、排出及び吸引のチューブ接続端を集約してセットするための水処理ユニットを必要とし、またその設置場所の選択及び、水回路殺菌並びに腐食防止のために、排出及び吸引チューブ接続端を一括して水処理ユニットにセットし操作する作業を必要とした。また、コップ給水及びスピットン洗浄用水回路の殺菌水による滅菌はなかった。本発明においては、上記課題を解決する装置を提供する。
【０００４】
【課題を解決するための手段】
本発明者は上記に鑑み鋭意研究の結果、下記の手段により上記課題を解決した。
（１）歯科用チェアユニットの水回路処理機構において、インスツルメントの水回路に殺菌水を充満させておく制御回路と、前記インスツルメントの水回路に充満させた殺菌水を、一旦殺菌水生成装置側に移送して、前記インスツルメントの水回路を空にする制御回路と、移送後空になった前記インスツルメントの水回路に、洗浄水を充満する制御回路とを有し、さらにそれら回路の切り替え手段を設けてなることを特徴とする歯科治療装置。
（２）インスツルメントが、インスツルメントホルダに設置されたままの状態で、その水回路の滅菌並びに腐食、劣化の防止を行うものであることを特徴とする（１）項に記載の歯科治療装置。
（３）歯科用チェアユニットの、コップ給水用及びスピットン洗浄用の水回路を、殺菌水並びに洗浄水の供給回路から分岐して設けたことを特徴とする（１）項に記載の歯科治療装置。
【０００５】
【発明の実施の形態】
本発明においては、水回路用殺菌水生成装置、水回路切換制御部および水回路切換弁等は、チエアユニットのチェア台座の内部に収納されており、また排出用のインスツルメントは従来通りインスツルメントホルダに収納したまま、水回路の滅菌並びに腐食や劣化を防止している。また、コップ給水及びスピットン洗浄用の水回路はスピットンの内部に収納されている。
以下、その構造及び作用を図に基づいて説明する。
【０００６】
【実施例】
図１は、本発明の装置を収納した歯科治療装置の外観斜視図、である。図において、１はチェアユニット、２はブラケットテーブル、３はインスツルメントホルダ、４はチェア台座、５、６はエアタービンハンドピース、７はマイクロモータハンドピース、８はスケーラ、９はスリーウェイシリンジの各インスツルメント、１０はチェア、１１はスピットン、１２は補助者用テーブル、４３はコップ給水管、４４はコップ置口、４５はスピットン洗浄管、４６はスピットン排出孔、をそれぞれ示す。
水回路用殺菌水生成装置、水回路切換制御部および水回路切換弁等（後記）は、チエアユニットのチェア台座４の内部に収納されている。
また、インスツルメントのエアタービンハンドピース５、６、マイクロモータハンドピース７、スケーラ８、スリーウェイシリンジ９の各インスツルメントは図示するように、インスツルメントホルダ３に収納されままの状態で、水回路内の滅菌並びに酸化による腐食、劣化を防止している。
また、コップ給水３５及びスピットン洗浄用３６の水回路はスピットンの内部に収納されている。
【０００７】
図２は、本発明装置のブロックダイヤを示す。以下図に基づいて、作用を説明する。
図において、１３は洗浄水（水道水）の流入方向、１４は殺菌水生成装置、１５は水回路切換制御部、１６はリニヤアクチエータ、１７、１８、１９、２０、２１はバルブ、２２、２３、２４、２５、４２はソレノイドバルブ、２６は分岐用具、２７は逆止弁、２８はインスツルメントの水回路、３０、３１は洗浄水の水回路、３３，３４は２方向切換器、３５はコップ給水水回路、３６はスピットン洗浄水回路、３７は給水管、３８は排水管、３９は外部排出管への排出方向、４０、４１は逆止弁をそれぞれ示す。
【０００８】
まず、排出器側水回路の作用を説明する。
水回路３１のソレノイドバルブ２２〜２５、４２は閉じられており、また逆止弁２７により、殺菌水が流入しないようにしている。
洗浄水は、洗浄水（水道水）の流入方向１３のように流入し、そして洗浄水の水路３０を通って殺菌水生成装置１４に供給される。
ここで生成された殺菌水は、リニヤアクチエータ１６によって、殺菌水の水回路２９を通ってバルブ１７〜２１、分岐用具２６、及び排出器の水回路２８を経て前記エアタービンハンドピース５、６、マイクロモータハンドピース７、スケーラ８、スリーウェイシリンジ９の各インスツルメントに供給されており、施療者はインスツルメントの手元の切り換えスイッチ（図示せず）をＯＮすることにより殺菌水を排出することができる。
上記は、施療時の使用状態であり、この状態では前記水回路は殺菌水により充満されていて常に、滅菌されている状態にある。
【０００９】
次ぎに、施療が終了し前記殺菌水（例えば、ソフト酸性水）により水回路が酸化により腐食や劣化するのを防止するために、前記水回路にある殺菌水を、前記リニヤアクチエータ１６を作動させて移送させインスツルメントの水回路を一旦空の状態にする。
また、このとき前記のインスツルメント５〜９は、インスツルメントホルダ３に収納されている状態であり、前記手元のスイッチはＯＦＦ（図示せず）になっている。
そして、バルブ１７〜２１を閉じると殺菌水は生成装置１４のリニヤアクチエータ１６と前記バルブ１７〜２１間に残留することがあるが、この間の水回路は酸化されない材質例えば塩化ビニール等により構成されているので腐食や劣化防止対策は必要としない。
【００１０】
さらに上記に説明した、空になっているインスツルメント側の水回路の酸化による腐食や劣化の防止対策として、まず、洗浄水の水回路３１に流入している水を、ソレノイドバルブ２２〜２５、４２を開き、分岐用具２６を介して前記空になっているインスツルメント側水回路のインスツルメント５〜９に供給する。
こうして、水回路は洗浄水によって充満されるため、仮に前記殺菌水が多少残留していたとしても希釈され、酸化の度合いは僅少であり、水回路の腐食や劣化防止の目的を達成することができる。
なお、以上説明した水回路のリニヤアクチエータ１６、バルブ１７〜２１、ソレノイドバルブ２２〜２５、４２等のタイミングによる開閉は、水回路切換制御部１５の作動により操作される。以上はインスツルメント側の処理の説明である。
【００１１】
次ぎに、コップ給水及びスピット洗浄水回路の作用について説明する。
図において、滅菌時には前記洗浄水の水回路に連結されている２方向切換器３４は閉じられ、２方向切換器３３は開かれており、殺菌生成装置１４のからの殺菌水は、コップ給水３５及びスピットン洗浄３６の水回路に供給される。
この殺菌水は前記水回路を通って排水管３８に流れ、外部排出管への排出方向３９のように排出され、水回路は滅菌される。
上記作用の後、２方向切換器３３は閉じられ、２方向切換器３４が開かれて、洗浄水が、コップ給水３５及びスピットン洗浄３６の水回路に供給される。
この洗浄水は前記水回路を通って排出管３８に流れ、外部排出管への排出方向３９のように排出され、水回路は洗浄されるとともに、水回路の酸化による腐食や劣化を防止している。
なお、逆止弁４０、４１は、インスツルメント側水回路と、コップ給水、スピットン洗浄側水回路の、洗浄水及び殺菌水の供給が混合されることを防止している。以上の作動のタイミングは、前記排水器側水回路の作動と同期させて実施するものとする。
【００１２】
【発明の効果】
本発明によれば、次ぎに示す優れた効果が発揮される。
１、本発明の請求項１及び請求項２の発明によれば、
歯科用チェアユニットの水回路処理機構において、インスツルメント内の水回路に殺菌水を充満させておく制御回路と、前記インスツルメントの水回路に充満させた殺菌水を一旦殺菌水生成装置側に移送して、前記インスツルメントの水回路を空にする制御回路と、移送後空になった前記インスツルメントの水回路に、洗浄水を充満する制御回路を有し、さらにそれら回路の切替え手段を設けてなるため、排出作用をもつインスツルメント側の水回路を、インスツルメントをインスツルメントホルダにセットしたままの状態で、滅菌しかつ、酸化による腐食や劣化の防止を行うことができる。
２、本発明の請求項３の発明によれば、
チェアユニットにおいて、コップ給水及びスピットン洗浄用水を、インスツルメント用殺菌水及び洗浄水回路から分岐して設けたため、両者が同時に水回路の残留水を滅菌し、かつ酸化による腐食や劣化を防止することができる。

[0007]
FIG. 2 shows a block diagram of the apparatus of the present invention. The operation will be described below with reference to the drawings.
In the figure, 13 is a flow direction of washing water (tap water), 14 is a sterilizing water generator, 15 is a water circuit switching control unit, 16 is a linear actuator, 17, 18, 19, 20, and 21 are valves, 22, 23, 24, 25 and 42 are solenoid valves, 26 is a branching tool, 27 is a check valve, 28 is an instrument water circuit, 30 and 31 are wash water circuits, 33 and 34 are two-way switches, 35 is a cup water supply circuit, 36 is a spitton washing water circuit, 37 is a water supply pipe, 38 is a drain pipe, 39 is a discharge direction to an external discharge pipe, and 40 and 41 are check valves.
[0008]
First, the operation of the discharger- side water circuit will be described.
The solenoid valves 22 to 25 and 42 of the water circuit 31 are closed, and the check valve 27 prevents the sterilizing water from flowing in.
The washing water flows in as in the inflow direction 13 of the washing water (tap water), and is supplied to the sterilizing water generator 14 through the washing water channel 30.
The generated sterilized water, depending on the linear activator eta 1 6, valves 17-21 through the water circuit 29 of sterile water, branching devices 26, and ejector of the through water circuit 28 air turbine handpiece 5 , 6, micromotor handpiece 7, scaler 8, and three-way syringe 9 are supplied to each instrument, and the user turns on a change-over switch (not shown) at the hand of the instrument to sterilize water. it is possible to leave wearing.
The above is a use state at the time of treatment, and in this state, the water circuit is filled with sterilized water and is always sterilized.
[0009]
The next, the treatment is finished the sterilizing water (e.g., soft acid water) to the water circuit can be prevented from corrosion or deterioration by oxidation, the sterilizing water is previously Kisui circuit, the linear activator eta 16 once the water circuit of the instrument is sent moved by work moving to the empty state.
Also, the instrument 5-9 of the this time is the state of being housed in the instrument holder 3, the hand switch is turned OFF (not shown).
When the valves 17 to 21 are closed, the sterilizing water may remain between the linear actuator 16 of the generator 14 and the valves 17 to 21, but the water circuit in the meantime is made of a material that is not oxidized, such as vinyl chloride. Therefore, no measures to prevent corrosion and deterioration are required.
[0010]
Further, as a countermeasure for preventing corrosion and deterioration due to oxidation of the empty water circuit on the instrument side described above, first, water flowing into the water circuit 31 of the cleaning water is supplied to the solenoid valves 22 to 25. , 42 is supplied to the instruments 5 to 9 of the empty instrument side water circuit through the branching tool 26.
Thus, since the water circuit is filled with the washing water, even if the sterilizing water remains to some extent, the water circuit is diluted and the degree of oxidation is small, and the purpose of preventing corrosion and deterioration of the water circuit can be achieved. it can.
Note that the water circuit linear actuator 16, the valves 17 to 21, the solenoid valves 22 to 25, and the like are opened / closed by the operation of the water circuit switching control unit 15. The above is a description of the processing on the instrument side.
[0011]
Next, the operation of the cup water supply and spit washing water circuit will be described.
In the figure, at the time of sterilization, the two-way switch 34 connected to the washing water circuit is closed, the two-way switch 33 is opened, and the sterilization water from the sterilization generator 14 is supplied to the cup water 35. And supplied to the water circuit of the Spitton cleaning 36.
The sterilized water flows through the water circuit to the drain pipe 38 and is discharged in a discharge direction 39 to the external discharge pipe, and the water circuit is sterilized.
After the above operation, the two-way switch 33 is closed, the two-way switch 34 is opened, and the cleaning water is supplied to the water circuit of the cup water supply 35 and the spitton cleaning 36.
This washing water flows through the water circuit to the discharge pipe 38 and is discharged as in the discharge direction 39 to the external discharge pipe. The water circuit is washed, and corrosion and deterioration due to oxidation of the water circuit are prevented. Yes.
The check valves 40 and 41 prevent the supply of the cleaning water and the sterilizing water of the instrument side water circuit and the cup water supply and spitton cleaning side water circuit from being mixed. The timing of the above operation shall be carried out in synchronization with the operation of the drainer side water circuit.
[0012]
