Abstract
Description
本発明は、強力な酸化力で微生物細胞を構成する蛋白をごく短時間に分解し、その結果微生物を死滅させる効果のある二酸化塩素の水溶液を、有効適正濃度に自動希釈する方法である。 The present invention is a method for automatically diluting an aqueous solution of chlorine dioxide having an effect of degrading a protein constituting a microbial cell with a strong oxidizing power in a very short time and, as a result, killing the microorganism, to an effective appropriate concentration.
従来から医療施設における医療器具の消毒にはグルタールやフタラールおよび過酢酸など使用されているが、これら薬液は毒劇物指定であるため、時には人体に障害を与えることから管理が重要であるとともに価格が高いため、使用者にとって少なからずの負担になっている。 Traditionally, glutar, phthalal, and peracetic acid have been used to disinfect medical devices in medical facilities, but since these chemicals are designated as poisonous and deleterious substances, management is important because they sometimes cause damage to the human body and cost. This is a considerable burden on the user.
二酸化塩素は化学薬品であり医薬品の承認は受けていないが、米国連邦ビルに対する炭素菌テロの館内消毒やアポロ宇宙船内の滅菌に使用されたり、上水道の消毒で使用されているなど、微生物に対する殺滅効果や人体への安全性は、国際的に認められている。 Chlorine dioxide is a chemical and has not been approved by the pharmaceutical industry. Destructive effects and human safety are recognized internationally.
二酸化塩素水溶液の製品は、二酸化塩素ガスが遊離状態で最大２，０００ｐｐｍ溶け込んでいる、それを微生物殺滅などに使用する場合の適正濃度は１０〜５０ｐｐｍであるため、希釈して使用しなければならない。 The product of chlorine dioxide aqueous solution is dissolved in a maximum of 2,000 ppm of chlorine dioxide gas. The appropriate concentration when using it for killing microorganisms is 10 to 50 ppm. Don't be.
二酸化塩素は１０℃以上の温度と紫外線によって単時間で揮発及び分解するため、希釈水を安定保管することが難しい、使用直前に適正濃度に希釈する必要がある。 Chlorine dioxide volatilizes and decomposes at a temperature of 10 ° C. or higher and ultraviolet light in a single hour, so it is difficult to stably store diluted water, and it is necessary to dilute it to an appropriate concentration immediately before use.
二酸化塩素は強い酸化性刺激臭があるため、呼吸器や眼などに障害を与える可能性があり、人手による希釈作業は防護具の装着が必要である。
また自動希釈するためには、強力な酸化腐食力による影響を避けるため、送液ポンプや電磁弁などを、高度の耐酸性を備えた素材の、高価な器材を使用しなければならない。Chlorine dioxide has a strong oxidative irritating odor, which may cause damage to the respiratory organs and eyes, and manual dilution requires wearing protective equipment.
In order to automatically dilute, in order to avoid the influence of strong oxidative corrosive force, liquid pumps and solenoid valves must be made of expensive equipment with high acid resistance.
本発明は、二酸化塩素原液をポンプで直接くみ上げるのではなく、密閉された希釈槽内の水をポンプでくみ上げて、それによる吸引力を利用して二酸化塩素原液を希釈槽内にくみ上げる方法である。 The present invention is not a method of directly pumping up a chlorine dioxide stock solution with a pump, but a method of pumping up water in a sealed dilution tank and pumping up the chlorine dioxide stock solution into the dilution tank using the suction force generated by the pump. .
このようにすれば、耐酸性ではない低価格のポンプを使用した、耐久性が高く安価な自動希釈装置を作成することが出来、使用の都度精度の高い二酸化塩素希釈液を、安全に供給することが可能となる。 In this way, it is possible to create a highly durable and inexpensive automatic dilution device using a low-priced pump that is not acid-resistant, and safely supply a highly accurate chlorine dioxide dilution liquid each time it is used. It becomes possible.
