Aspect the sterilization in the confined space of for example ambulance inside, must carry out a time-consuming disinfection after the common cleaning of routine, this work comprises the process of using scrubbing tool and disinfectant solution to clean.
For example, because ambulance is the treatment that is used for carrying patient and gives patient's initial stage simultaneously, so ambulance must keep certain clean level at least, and for this purpose, conventional sterilization is an important step.Generally believe that the average viable count of coliform bacteria, staphylococcus, common bacteria, fungus etc. should not surpass 10 colony-forming units (CFU/10cm
2), preferably should not surpass 5CFU/10cm
2| Kyukyu Iryo no Kiso to Jissai:1 Kyukyu Gyomu to Kyukyu Iryo| (basis and the practice of urgent medicine: 1 urgent management and urgent medicine, the urgent editor of office of capital, Tokyo fire prevention committee, Joho Kaihatsu Kenkyusho publishes).
Traditional sterilisation step comprises and uses for example dilute aqueous solution of certain disinfectant of cresol, carries out manual scrub clean or sprays cleaning by manual operations or power driven decontamination apparatus.Under some special or inevitable situation, adopted disinfectant solution, and glutaraldehyde is known as a kind of effective antibacterial/disinfectant based on glutaraldehyde.Therefore, for example glutaraldehyde is diluted with water to concentration and is approximately 1～2% and use glutaraldehyde by scrub clean.
Yet traditional sterilisation step is sterilized completely owing to it almost can not arrive all corners and shelter, and is therefore not only time-consuming but also insufficient.And when using diluted disinfectant solution by sprinkling, water is retained on the plane of handling, and can not obtain desired Disinfection Effect in the zone in corner, thereby can not reach gratifying result.
In addition, when described glutaraldehyde was used for scrub clean, zest and pungent abnormal smells from the patient can last very longs.Like this, abnormal smells from the patient remains on and reaches 12～24 hours in the air.
Summary of the invention

Compositions described in the present invention is to mix temporarily by the buffer solution that the alcohol that will contain 65～80%, percentage by volume are that basic mixture and for example percentage by volume of the perfume of 10～20% 20% glutaraldehyde (water) solution and 0～5% is 3～7%, concentration is 1.0～2.0% diethanolamine aqueous solution to be prepared from.
Like this, because glutaraldehyde has penetrating odor, must use forced ventilation such as fan to carry out each step cleaning of back, so preferably add above-mentioned perfume to cover niff, the perfume described in the present invention is for can play the commercially available perfume of covering the penetrating odor effect.
In addition, if the concentration of the glutaraldehyde that uses in this mixes is less than 2%, then Disinfection Effect will significantly descend, and the glutaraldehyde concentration of use can not reach ideal effect above 4%, because the strong impulse abnormal smells from the patient is sent in such meeting in the cleaning course of back and abnormal smells from the patient is prolonged diffusing afterwards in cleaning.
The concentration of alcohol should be in above-mentioned 65～80% scope in the antiseptic composition, because too much all can cause the disinfectant deleterious with insufficient alcohol amount.Above-mentioned high concentration alcohol can be the alcohol with high concentration of suitable volatility and bactericidal activity, and for example ethanol, methanol or concentration are not less than 80% isopropyl alcohol or with the corresponding alcohol of some denaturant degeneration.For example, described denatured alcohol can be by obtaining high concentration ethanol and denaturant mixing, described denaturant can be methanol, isopropyl alcohol etc., perhaps, more specifically say so by 5 kilogram 95% methanol is joined obtain in per 200 liter 95% ethanol so-called through methanol modified alcohol.Because use ethanol cost height separately, therefore preferably use for example above-mentioned denatured alcohol through methanol modified alcohol and so on, consider also that from the angle of safety working concentration effectively is 80～90% isopropyl alcohol.
Use above-mentioned antiseptic composition, rely on the disinfectant glutaraldehyde can obtain fabulous Disinfection Effect.Therefore, glutaraldehyde is a kind of material with synthetic chemistry character, and has shown and can kill various bacteria, tulase, fungus, sporeformer and virus.Use this glutaraldehyde solution of alcohol dilution can produce enough Disinfection Effects.Particularly because described basic high concentration alcohol is the diluent as glutaraldehyde, glutaraldehyde is diluted well, in addition, itself has also brought into play fabulous Disinfection Effect the alcohol of described high concentration, to such an extent as to even use the glutaraldehyde of medium consumption also can obtain enough effects.
In addition, because described antiseptic composition includes buffer solution, use the pH value of solution can remain between about 7.5～8.5, thereby Disinfection Effect can continue about 10 days after using.In addition, add to the penetrating odor of eliminating glutaraldehyde of great use as the perfume of masking agent.
And, because antiseptic composition of the present invention can be easy to obtain by the described buffer solution that contains the basic pure and mild for example diethanolamine aqueous solution of 20% commercial glutaraldehyde solution is mixed, described basic alcohol can be selected ethanol, the isopropyl alcohol of high concentration or the denatured alcohol of making by the denaturant that uses methanol and so on for use, can optionally add perfume as mentioned above, therefore, antiseptic composition of the present invention is easy to preparation in the art and uses.
