Description
Technical field
The present invention relates to the disinfection cleaning solution technology, relate in particular to preparation method and equipment that a kind of grade is oozed disinfection cleaning solution.
Background technology
In the medical treatment of sudden public health event, natural calamity and war, the usage amount of thimerosal, cleaning wound liquid is very large, and is that heavy dose of concentrating used in the short time.Present employed thimerosal, cleaning fluid mostly are liquid dosage form, and inconvenient, the urgent supply of transportation is very difficult.In addition, solid disinfecting agent preparation water also is a difficult problem, adopts the dissolving of unpurified water source, dilution solid disinfecting agent, all can reduce significantly disinfection effect.Therefore, be badly in need of a kind of efficient, quick-acting, wide spectrum, nontoxic, noresidue, pollution-free to personnel, animal, soil, plant harmless, non-stimulated disinfection cleaning solution all, are used for cleaning and the sterilization of wound and the surface of a wound and ward, sick bed, clothing, medicine equipment, environment.
Oxidizing potential disinfectant (also claiming acidic oxidized electric potential water, strong peroxide deionized water, strong acidifying water etc.) is a kind of Novel sterilizing water that occurred in the last few years, make by the certain density NaCl aqueous solution of electrolysis, have low pH value, high redox potential (ORP), contain the characteristics such as low concentration available chlorine, be written into health ministry " disinfection technology standard " in 2002.It has following features: itself has disinfecting and sterilizing functions, sterilization rapidly, efficient, cost is low, and is processing noresidue on the object, to human body without cumulative toxicity, environmentally safe.Because it has so physicochemical property and the simplicity on producing, it is had wide practical use at aspects such as food hygiene, medical and health, clinical and health and epidemic preventions.
At present, have much about the preparation method of oxidizing potential disinfectant and the research of equipment both at home and abroad, but mostly for agricultural, life drink, the cleaning and sterilizing of environment disinfected and medicine equipment.Wherein, will have the oxidizing potential disinfectant now is used for also needing to use medical purified water to clean after medicine equipment cleans.Existing oxidizing potential disinfectant preparation technology can not well remove the organic matter that exists in the water, and the foreign matters such as particle, foreign ion can not satisfy being applied to the needs that sterilization is cleaned on human body wound, the surface of a wound fully; And the ion concentration of oxidizing potential disinfectant and human body fluid differ greatly, and has osmotic pressure, and pain was stronger when sterilization cleaned a wound, and the wounded was caused additional painful.For example: patent 200620018031.0 discloses a kind of agricultural electrolytic water generator, consisted of by elements such as water softener, electrolytic water generator and storage tanks, the acidulous water of producing is used for killing the bacterial virus on crops, the fruit, and alkaline water can be used for irrigating.Wherein, acting as of water softener removes the hardness processing to former water, alleviates the scale formation in the electrolytic process.Application number is that 200510111565.8 document discloses a kind of method for water is carried out electrolysis, produces alkaline water and drinks.It carries out electrolysis after adopting the water of partly removing electrolyte ion and the water of partly not removing electrolyte ion to mix with certain proportion, to reduce the ion concentration in the water, makes product water be alkalescent, for drinking.Patent 200710164297.5 discloses a kind of method that Oxidized Electric Potential Generator is carried out intelligent control, by controller regulating impulse salt pump frequency, decomposition voltage, electric current, to guarantee effluent index.Application number is that 200710017331.6 document and patent 200710017332.0 disclose respectively self-suction type strong electrolyzing activating tank and continuous electrolyzing to make water overlapped activating tank, and electrolysis unit is designed.Patent 03218790.4 discloses a kind of electrolytic activation slot for the production of drinking water and disinfectant, adopts siphoning installation to add electrolyte.Application number is that the document of 200520079371.X discloses a kind of titanium cathode for electrolyzing water, has prolonged the service life of electrode as cathode for electrolyzing with the titanium battery lead plate.Patent 200620119291.7 discloses a kind of electrolyzed oxidizing water process units, and it does not relate to the processing procedure of former water, utilizes the soft water that has softened after processing to carry out electrolysis, carries out electrolytic process control by valve, control system.Application number is 200910201428.1 document, discloses a kind of disinfectant fluid production line standard, can produce acid disinfectant and clean and safe band alkalescent drink water.
Find by analyzing, the prior art of existing electrolytic oxidation current potential disinfectant mainly concentrates on design and the aspects such as the preparation of alkaline drinking water and disinfection of drinking water of electrolysis unit, still can not meet the needs that medical aspect is cleaned sterilization: the medical cleaning fluid that 1, does not clean for sterilizations such as wound, the surface of a wound specially.The design of the aspects such as existing brine electrolysis technology its preparation method, technological process, electrolytic condition can not be used for the upper cleaning and sterilizing to wound, the surface of a wound of medical treatment mainly for the use of agricultural, the aspects such as drinking of living.2, the treatment and purification to water is not enough.The conventional methods such as multistage filtering can not be removed the impurity such as ion in the water, organic matter, and easily stop up, not easy cleaning.The cleaning and sterilizing water of wound must satisfy the certain purity requirement, and the existence of bacterium, organic matter and foreign ion can affect service life, the purity of disinfection cleaning solution, cleaning and sterilizing effect, the storage life of equipment, even human body is caused secondary damage.3, exist permeable pressure head between common oxidizing potential disinfectant and the wound, pain was stronger when sterilization cleaned a wound, and the wounded was caused additional painful.
