Description
Technical field
The invention belongs to medical accessory technical field, be specifically related to a kind of medical vessel macula lutea clean-out system and preparation method thereof.
Background technology
Hospital department is commonly used various metalwares, as kidney basin, dressing bowl, scalpel, mosquito forceps, tweezers etc.In use for some time, surface there will be yellow or brown spot and speckle to metal, even occurs the situation of the equal flavescence of all surface.The yellow dirt of this class is used conventional acidity or alkaline cleansing agent to be all difficult to remove, and this not only affects the attractive in appearance of vessel but also has a strong impact on cleaning quality and sterilising effect.
Although use highly acid clean-out system also can remove this type of macula lutea, because acidity can cause vessel surface rust corrosion after crossing strong cleaning.
Summary of the invention
For solving the problems of the technologies described above, the present invention proposes a kind of de-etiolation spot effective, and can not cause to metalware the medical vessel macula lutea clean-out system of corrosion.
Technical scheme of the present invention is: medical vessel macula lutea clean-out system, by weight percentage, its component is: phosphoric acid, 10-15%, oxalic acid, 5-10%, AEO-9(fatty alcohol-polyoxyethylene ether), 2-3% inhibiter: trihydroxy ethylamine oleate soap, 2-3%, nonionogenic tenside:, sequestrant: Sunmorl N 60S, 1-2%, sanitas, 0.02-0.05%, solvent: propylene glycol, 10-15%, deionized water, 50-70%.Described phosphoric acid concentration is 85%, and propylene glycol concentration is DOW Chemical 99%, and sanitas is Kathon CG or triclosan.
Above-mentioned oxalic acid, Sunmorl N 60S are analytical pure rank.
The preparation method of medical vessel macula lutea clean-out system of the present invention is: (1) adds deionized water in reaction vessel, turn on agitator; Then oxalic acid, Sunmorl N 60S, sanitas are once added, and continue to stir 60min; (2) use four layer of 300 order filter cloth to filter the mixing solutions making in step (1); (3) in the solution after step (2) is filtered, add phosphoric acid, trihydroxy ethylamine oleate soap, propylene glycol and AEO-9, and continue to stir 30min.
The using method of medical vessel macula lutea clean-out system of the present invention:
1, under normal temperature condition (20-25 ℃), pours clean-out system stoste in container into, then pending apparatus is soaked in stoste completely, and standing 6 hours, then apparatus is taken out, with after the thorough rinsing of clear water, dry.
2, under mesophilic condition (40-50 ℃), pours 1 part of clean-out system stoste in container into, then adds 1 part of soft water.Pending apparatus is soaked in obtain solution completely, standing 1 hour, then apparatus is taken out, with after the thorough rinsing of clear water, dry.
Medical vessel macula lutea clean-out system of the present invention is for the cleaning of medical vessel surface yellow spotting speckle.Medical vessel surface yellow spotting speckle main component is mineral grease, incrustation scale etc., and after dry, sterilizing repeatedly, wide variation have occurred its internal structure, and sticking power improves greatly, and conventional acidic cleaning agent and alkaline cleansing agent cannot play a role.Although strongly-acid clean-out system also can be removed dirt, because acidity is excessively strong, can cause being cleaned article excessive corrosion and get rusty.Phosphoric acid and oxalic acid in medical vessel macula lutea clean-out system of the present invention provide acidic conditions, and for incrustation scale class dirt, these two kinds of acid are middle strong acid, strong and corrosion-free to metal for the capacity of decomposition of incrustation scale class material, and good water solubility; In order to improve wetting speed and for the removal effect of mineral grease, to have added nonionogenic tenside AEO-9, this tensio-active agent can significantly reduce surface tension, and under sour environment water-soluble better, can meet the demands; Trihydroxy ethylamine oleate soap can reduce corrodibility to the full extent as inhibiter; Sunmorl N 60S provides good resistance to hard water as sequestrant, even still can play a role under hard water condition.
Beneficial effect of the present invention is: medical vessel macula lutea clean-out system de-etiolation spot of the present invention is effective, goes spot quick, and cleaning charge is low, easy to use, and stoste is soaked, reusable, has reduced use cost.And this clean-out system can not cause corrosion to metalware when cleaning, can prevent the rust corrosion phenomenon of vessel when cleaning and after cleaning, make vessel light as new, greatly extended the work-ing life of metalware.
