Description

本発明は、より衛生的な水を供給する減菌装置、および該減菌装置を組み込んだ医療装置に関する。   The present invention relates to a sterilization device that supplies more sanitary water and a medical device incorporating the sterilization device.

従来、歯科などの各種医療装置や手術器具などにおいては、患者の治療部位を治療の前後、または治療と同時に水洗するために、種々の形状の噴水・注水・洗浄装置が設けられている。これらの噴水装置などに水を供給するために元水に連結する各種のチューブやパイプが配設され、必要個所には貯留部が設けられ、また、噴水などに必要な動力源として小型モータなどが設けられている。   2. Description of the Related Art Conventionally, various medical devices such as dentistry, surgical instruments, and the like have been provided with various shapes of fountain / water injection / cleaning devices in order to wash a patient's treatment site before and after treatment or simultaneously with treatment. In order to supply water to these fountain devices, various tubes and pipes that are connected to the source water are provided, a storage section is provided at a necessary location, and a small motor or the like as a power source required for fountains, etc. Is provided.

上記装置に供給される水は、常に清浄であり、各種細菌が混入していないことが理想であることから、通常は酸や殺菌剤で処理された減菌水や殺菌水を使用することが考えられる。しかしながら、上記の如き処理水は薬剤を含有していることから、使用する治療機器や部品を腐食させたり、変色させたりするという弊害があり、さらには上記処理水は患者の患部や治療部位に供給されることから、減菌や殺菌に強力な薬剤を使用することができない。そのために熱や紫外線などにより減菌または殺菌処理が行なわれている。   It is ideal that the water supplied to the device is always clean and free of various bacteria, so it is usually recommended to use sterilized water or sterilized water that has been treated with an acid or disinfectant. Conceivable. However, since the treated water as described above contains chemicals, there is an adverse effect of corroding or discoloring the treatment equipment and parts to be used, and further, the treated water is applied to the affected area or treatment site of the patient. Because it is supplied, it is not possible to use powerful drugs for sterilization and sterilization. For this purpose, sterilization or sterilization is performed by heat or ultraviolet rays.

上記減菌水や殺菌水は、医療装置に供給される以前の減菌・殺菌処理時には充分なレベルに減菌・殺菌されているが、これらの処理水中では、医療装置内の給水流路中や貯留部において細菌や微生物が繁殖することがあり、特に医療装置が作動していない夜間などにおいて装置内で細菌が繁殖し、該細菌が繁殖した水が治療中に患者の患部や処置部位に供給され、衛生上の問題がある。このような問題は、医療装置が作動していない間は装置内の水を全て抜き取ることにより解決されると思われるが、実際には装置の使用後直ちに装置内の水を抜き取ることは煩雑であり、しかも装置内の水を完全に抜き取ることもできない。そのために装置の使用前に処理水を多量に流して装置内を洗浄するという煩雑な作業が要求されるので、多くの場合には水の交換を省略したり、不十分な交換で装置を作動させており、衛生上好ましくない。   The sterilized water and sterilized water are sterilized and sterilized to a sufficient level at the time of sterilization and sterilization before being supplied to the medical device. In these treated water, Bacteria and microorganisms may propagate in the storage area, especially at night when the medical device is not in operation, and the bacteria propagated in the device, and the water in which the bacteria have propagated may enter the affected area or treatment site of the patient during treatment. Supplied and has hygiene issues. Such a problem seems to be solved by draining all the water in the device while the medical device is not operating, but in practice it is complicated to drain the water in the device immediately after using the device. Moreover, the water in the apparatus cannot be completely removed. For this reason, a complicated work of flowing a large amount of treated water before the device is used to clean the inside of the device is required, so in many cases the replacement of water is omitted or the device is operated with insufficient replacement. This is undesirable for hygiene purposes.

従って本発明の目的は、上記の如き問題を解決し、治療装置に組み込まれた通水路中や貯留部中などにおける細菌の繁殖を抑え、より衛生的な水を供給できる減菌装置と該減菌装置を備えた治療装置を提供することである。   Accordingly, an object of the present invention is to solve the above-described problems, to suppress the growth of bacteria in a water passage or a storage part incorporated in a treatment apparatus, and to supply a more sanitary water and the sterilization apparatus. It is providing the therapeutic apparatus provided with the microbe apparatus.

上記目的は以下の本発明によって達成される。
１．中央に通水路を有する筒状本体と、該本体内の通水路の周辺に異磁極同士が対向するように配置された一対の永久磁石が少なくとも１対埋設されており、通水路の導水口と排水口が中央の通水路よりも大径に形成されていることを特徴とする水の減菌装置。
２．水路を有する医療装置において、該水路中に前記１に記載の減菌装置が少なくとも１個配置されていることを特徴とする医療装置。

2. A medical device having a water channel, wherein at least one sterilization device according to 1 is disposed in the water channel.
3. 3. The medical device according to 2 above, which is used for dentistry.

本発明によれば、治療装置に組み込まれた水路中などにおける細菌を減菌したり、細菌の繁殖を抑制することができる。特に本発明の減菌装置は歯科において使用する治療器具に応用した場合に特に有用である。   ADVANTAGE OF THE INVENTION According to this invention, bacteria in the waterway etc. which were integrated in the treatment apparatus can be sterilized, or propagation of bacteria can be suppressed. The sterilization apparatus of the present invention is particularly useful when applied to a therapeutic instrument used in dentistry.

次に発明を実施するための最良の形態を挙げて本発明をさらに詳しく説明する。
本発明の減菌装置Ａの１例を図１に示す。図１Ａは本発明の減菌装置の側断面図であり、図１Ｂは線Ｘ−Ｘの矢視断面図である。本発明の減菌装置は図示のように、中央に通水路１を有する筒状本体２と、該本体２内の通水路１の周辺に異磁極同士が対向するように配置された一対の永久磁石３，３’が３対埋設されており、通水路１の導水口４側と排水口５側が中央の通水路１よりも大径に形成されていることを特徴としている。なお、一対の永久磁石は１対でもよいが、通常は２〜５対を設けることが好ましい。Next, the present invention will be described in more detail with reference to the best mode for carrying out the invention.
An example of the sterilizer A of the present invention is shown in FIG. 1A is a side sectional view of the sterilization apparatus of the present invention, and FIG. 1B is a sectional view taken along line XX. As shown in the drawing, the sterilization apparatus of the present invention has a cylindrical main body 2 having a water passage 1 in the center, and a pair of permanent magnets arranged so that different magnetic poles face each other around the water passage 1 in the main body 2. Three pairs of magnets 3 and 3 ′ are embedded, and the water conduit 4 side and the drain port 5 side of the water passage 1 are formed to have a larger diameter than the central water passage 1. The pair of permanent magnets may be one pair, but usually 2 to 5 pairs are preferably provided.

上記において、通水路１や本体２の材料は、磁力線が貫通可能であるように、アルミニウム、ステンレス、合成樹脂などの非磁性材料で形成されており、通常はいずれも円筒形である。通水路１の周囲に配置された永久磁石３，３’は磁力が強大なネオジウム永久磁石であり、図示の例では、３対の磁石が、それぞれ異なる磁極が対向するよう、例えば、Ｓ−ＮやＮ−Ｓに配設されている。これらの磁石の形状は特に限定されないが、通水路１を取り囲むようにカマボコ形や扇形であることが好ましい。通水路１の両側の一方は導水口４であり、他方は排水口５である。上記の通水路内に水が流された場合、水は、通水路内において強力な磁力線に曝されるようになっている。   In the above, the material of the water passage 1 and the main body 2 is formed of a non-magnetic material such as aluminum, stainless steel, synthetic resin or the like so that the magnetic lines of force can be penetrated. The permanent magnets 3 and 3 ′ arranged around the water passage 1 are neodymium permanent magnets having a strong magnetic force. In the illustrated example, three pairs of magnets are arranged so that different magnetic poles face each other, for example, SN. And NS. Although the shape of these magnets is not particularly limited, it is preferably a kamaboko shape or a fan shape so as to surround the water passage 1. One of the both sides of the water passage 1 is a water inlet 4 and the other is a drain 5. When water is caused to flow through the water passage, the water is exposed to strong magnetic lines of force in the water passage.

図２には、上記減菌装置を配管６を切断し、配管に対して直列に接続した状態を示している。この状態で矢印に示すように通水すると、水は通水路中を通過している間に強力な磁力線に曝され、水中に混入している有機物（細菌、微生物など）が破壊され、減菌処理された水が排水口に流れる。このとき配管６の内径は導水口および排水口の径と同様であるが、通水路の径は上記の配管または導水口および排水口の径よりも小さく形成されており、通水路中を通過する水には集中した磁力線に曝される。処理水に対する磁力の効果は相対する磁石間の距離の２乗に反比例するので、相対する磁石間の距離をできるだけ小さくすることが好ましい。   FIG. 2 shows a state in which the sterilizer is cut in the pipe 6 and connected in series to the pipe. When water is passed as shown by the arrow in this state, the water is exposed to strong magnetic field lines while passing through the water channel, destroying organic substances (bacteria, microorganisms, etc.) mixed in the water, and sterilizing. Treated water flows to the drain. At this time, the inner diameter of the pipe 6 is the same as the diameter of the water inlet and the drain, but the diameter of the water passage is formed smaller than the diameter of the pipe or the water inlet and the outlet, and passes through the water passage. Water is exposed to concentrated magnetic field lines. Since the effect of the magnetic force on the treated water is inversely proportional to the square of the distance between the opposing magnets, it is preferable to make the distance between the opposing magnets as small as possible.

図３は、上記本発明の減菌装置を歯科用の処置装置（ユニット）に組み込んだ例を示している。歯科病院などにおいては、虫歯などの処置において水を噴霧しながら歯を研削或いは研磨する場合が多く、本発明の減菌装置はこのような歯科の治療装置に特に有用である。歯科の治療装置には、元水７から噴水電磁弁８、温水器９、温水トラップ１０などを経由して噴水装置１１に至る通水路；元水７からマルチシリンジ１２およびマルチシリンジ１３に至る通水路；元水７から、エア１９が吹き込まれる水切弁１４、スプレー水流量弁１５を経てエアタービン１６、１７、マイクロエンジン１８に至る通水路や貯留部２０などの各種の水路があり、装置の休止中にはこれらの水路中で細菌が繁殖し、患者の口腔内に細菌が混入する場合がある。このような歯科用処置装置（ユニット）Ｂの任意の水路に前記本発明の減菌装置Ａを組み込むことによって、装置の休止中における細菌の繁殖を抑制することができる。装置を組み込む位置は特に限定されないが、元水からの取水部、水滞留部、機器内配管部、配管分岐部、水の吐出部などが挙げられ、特に取水部と吐出部の両方に設けることが好ましい。   FIG. 3 shows an example in which the sterilization apparatus of the present invention is incorporated in a dental treatment apparatus (unit). In dental hospitals and the like, teeth are often ground or polished while spraying water in the treatment of caries, etc., and the sterilization apparatus of the present invention is particularly useful for such a dental treatment apparatus. The dental treatment apparatus includes a water passage from the source water 7 to the fountain device 11 through the fountain solenoid valve 8, the water heater 9, the hot water trap 10, etc .; the passage from the source water 7 to the multi syringe 12 and the multi syringe 13. There are various water channels such as water passages and reservoirs 20 from the source water 7 to the air turbines 16 and 17 and the micro engine 18 through the water drain valve 14 through which the air 19 is blown in, the spray water flow valve 15, and the device During the rest, bacteria may propagate in these waterways, and the bacteria may enter the patient's mouth. By incorporating the sterilization apparatus A of the present invention into an arbitrary water channel of such a dental treatment apparatus (unit) B, it is possible to suppress the growth of bacteria during the rest of the apparatus. The position where the device is installed is not particularly limited, but examples include the intake section from the original water, the water retention section, the piping section in the equipment, the piping branch section, the water discharge section, etc., especially in both the intake section and the discharge section. Is preferred.

本発明の減菌装置の応用例として歯科用処置装置を挙げて説明したが、本発明は、水路を有しているその他の医療装置にも同様に適用することができ、同様に衛生的な水を供給することができる。   Although the dental treatment apparatus has been described as an application example of the sterilization apparatus of the present invention, the present invention can be similarly applied to other medical apparatuses having a water channel, and is similarly hygienic. Water can be supplied.
