Definitions

  • the present invention relates to a two-part cleaning and disinfection system. This system finds particular application in the field of cleaning and disinfection of medical equipment and instruments, including endoscopes.
  • a cleaning wipe impregnated with a detergent solution For both cleaning and disinfecting, it is now necessary to use different types of wipes: first a cleaning wipe impregnated with a detergent solution, then at least one disinfectant wipe.
  • a cleaning wipe impregnated with a detergent solution For example marketed by the company Tristel (Snailwell, Cambridgeshire, United Kingdom) under the name "Tristel Trio ® Wipes System”.
  • Tristel Trio ® Wipes System This system consists of a detergent wipe, a sporicidal wipe and a rinsing cloth impregnated with demineralized water. Each wipe is supplied in a unit bag.
  • Tristel The cleaning and disinfection system offered by Tristel has the disadvantage that it requires two different wipes, one for cleaning and one for disinfection, which can be a source of error. Indeed, once unpacked it is not possible to instigate with the naked eye the detergent wipe of the disinfectant wipe.
  • the packaging of the Tristel Trio ® system is complex and unecological due to the principle of the unit bag. There is therefore a need for a disinfection and cleaning system for cleaning and disinfecting medical equipment and instruments that is easier to use than the Tristel Trio ® system .
  • An object of the invention is therefore a two-part cleaning and disinfection system comprising:
  • a first part comprising at least one non-woven support of a detergent solution
  • a second part comprising a container containing a disinfectant liquid composition
  • the detergent solution comprises a color pH indicator
  • the composition disinfectant comprises at least one peracid which produces a colorimetric reaction with the pH indicator when it is brought into contact with the nonwoven support.
  • This system has the advantage that the non-woven support of a detergent solution is versatile. It can on one side be used as is for cleaning and on the other side it serves as a substrate for the disinfectant composition.
  • the disinfectant composition is applied to the nonwoven support impregnated with a detergent solution and is uniformly penetrated throughout the support.
  • the detergent solution whose nonwoven support is impregnated comprises a color pH indicator makes it possible to ensure that the peracetic acid is distributed homogeneously over the entire support by the appearance of an uniform coloration. .
  • the disinfecting power is directly provided by the organic peracid of the disinfecting composition and not the result of a chemical reaction between a first reagent, an organic acid, present in the nonwoven support and a second reagent, sodium chlorite, brought in the form of foam. This has the advantage of greater reproducibility of the disinfecting power since it is not subject to the hazards of a chemical reaction.
  • the peracid is advantageously chosen from aliphatic peracids, in particular from C2 to C4.
  • the disinfectant composition comprises at least peracetic acid.
  • the peracid, in particular peracetic acid may be used alone or in admixture with another peracid.
  • the peracid content of the disinfecting composition is advantageously from 0.1 to 2% by weight, preferably from 0.4 to 1.6%, by weight relative to the total weight of the disinfecting composition.
  • the disinfectant composition also comprises hydrogen peroxide, preferably in an amount of 3 to 25%, preferably 3 to 15% by weight relative to the total weight of the composition.
  • the disinfectant composition is formulated in liquid form. It may be contained in any container suitable for the distribution of this type of product.
  • suitable containers include spray bottles, especially trigger bottles, dosing pump bottles, bottles with foam dispensers, flasks with flap cap and drop-edge bottles.
  • the disinfectant composition can be applied in the form of foam on the nonwoven support with the aid of a suitable dispensing container.
  • a suitable dispensing container Such containers are well known to those skilled in the art and include in particular the bottles with foam dispenser.
  • Applying the liquid composition in the form of foam facilitates the absorption of the disinfectant composition and makes it easy to control the amount of peracid applied to the nonwoven support because the foam is visible before it enters the support .
  • the use of a foam limits the odor of the peracid, in particular peracetic acid.
  • the foaming agents being well known to those skilled in the art, the latter will know how to choose a suitable one.
  • Non-limiting examples of foaming agents include amine oxide surfactants, such as dimethyl laurylamine oxide, lauryl sulphate anionic surfactants, lauryl ether sulphate, dodecyl benzene sulphonate or nonionic surfactants such as alkyl polyglucosides, or fatty alcohols. alkoxylates, especially ethoxylated fatty alcohols.
  • the liquid disinfectant composition is non-foaming and can therefore be applied, for example, by spraying the nonwoven support.
  • the disinfectant composition is preferably an aqueous composition. It may further comprise additives such as stabilizing agents such as dipicolinic acid and phosphonates.
  • the nonwoven support impregnated with the detergent solution is advantageously contained in a container that is airtight and watertight in order to prevent it from drying out. It may for example be a resealable container that can contain a plurality of wipes or a unitary package containing a single wipe, such as a sachet.
  • reclosable containers include resealable bags, boxes with resealable lid and / or provided with a resealable dispensing orifice, buckets with reclosable lid and / or provided with a resealable dispensing orifice.
  • the nonwoven support is composed of a plurality of wipes.
  • This plurality of detachable wipes may for example be in the form of a roller.
  • This roller can in particular be provided in a closed bucket provided with a resealable dispensing orifice.
  • the user can detach one or more wipes according to his needs and then close the bucket for later use of the remaining wipes.
  • the nonwoven support may be of natural and / or synthetic fibers.
  • the fibers are chosen from viscose, polyester, polyethylene and polypropylene fibers, and mixtures thereof.
  • Particularly interesting results have been obtained with 100% viscose wipes. Indeed, this type of wipe allows a homogeneous and stable distribution of the detergent solution and thus avoids the phenomenon of decantation of the detergent solution in time observed with other types of wipes. This phenomenon is particularly pronounced when the nonwoven support is a roll of wipes positioned vertically in a container such as a bucket. In this case, the detergent solution accumulates in the bottom of the wipes which decreases cleaning performance of wipes.
  • Other suitable fibers that can be used in the context of the invention are well known to those skilled in the art.
  • the impregnation rate of the wipes with the detergent solution is advantageously from 100 to 500% by weight, preferably from 200 to 400% by weight and more preferably from approximately 300% by weight relative to the dry weight of the wipes.
  • the detergent solution with which the nonwoven support is impregnated is preferably an aqueous solution comprising a mild alkalizing agent.
  • This mild alkaline agent is preferably selected from aminoalcohols, alkali or alkaline earth carbonates and mixtures thereof.
  • the aminoalcohol is chosen from monoethanolamine, triethanolamine and 2-amino-2-methyl-1-propanol. More preferably, it is triethanolamine.
  • the mild alkalizing agent is advantageously contained in the detergent solution in an amount of from 0.1 to 2%, preferably from 0.2 to 1% and more preferably from 0.25 to 0.6%, for example from about 0.3% by weight based on the total weight of the solution.
  • the detergent solution comprises tritethanolamine, preferably in an amount of 0.25 to 0.6%, for example about 0.3% by weight based on the total weight of the solution.
  • triethanolamine especially in the amounts indicated, is particularly advantageous when the cleaning and disinfection system according to the invention is used for the surface treatment of polycarbonate, a polymer commonly used in the field.
  • Polycarbonate is indeed ubiquitous in health facilities, it is particularly a constituent material of the fairing of medical devices such as transesophageal probes, hemodialysis generators, ultrasonic probes, electronic thermometers etc.
  • Polycarbonate is a ductile and fragile polymer with a high sensitivity to contact with chemicals. This sensitivity is characterized by a phenomenon of cracking (English: stress cracking) with the consequence, in case of repeated application of a detergent or a disinfectant not compatible with the polycarbonate, a depolymerization of the polycarbonate. The latter usually has a corollary fragility and then breaks the medical device.
  • the detergent solutions according to the invention containing triethanolamine minimize or even avoid the occurrence of cracking phenomenon (stress cracking) in the polycarbonate after repeated applications.
  • the pH of the detergent solution is preferably slightly alkaline, preferably 7.5 to 8.5, more preferably about 8.
  • the detergent solution may also include one or more surfactants.
  • These surfactants are preferably chosen from nonionic, amphoteric surfactants and mixtures thereof.
  • Nonlimiting examples of nonionic surfactants include alkylpolyglucosides, alkylpolypentosides, amine oxides, polyglycosides, glucamides, polyalkoxylated fatty alcohols, in particular polyethoxylated fatty alcohols, and ethoxylated fatty acid esters, oxides of amino being preferred.
  • Non-limiting examples of amphoteric surfactants include cocamidopropyl betaines.
  • the surfactant or surfactants are advantageously contained in the detergent solution in an amount of from 0.001 to 2%, preferably from 0.01 to 0.1% and even more preferably from 0.025 to 0.05% by weight relative to the total weight of the composition.
  • the color pH indicator included in the detergent solution may be chosen from all those which give rise to a colorimetric reaction in contact with the peracid of the disinfecting composition.
  • Nonlimiting examples of pH indicator that may be used in the context of the present invention include phenol red, bromothymol blue, thymol blue, methyl yellow, methyl orange, bromophenol blue, bromcresol green, methyl red, phenolphthalein, alizarin yellow and cresol red.
  • the pH indicator is methyl red.
  • the pH indicator is advantageously contained in the detergent solution in an amount of 3 to 15 ppm, preferably 5 to 10 ppm and more preferably still 7 to 8 ppm by weight relative to the total weight of the composition.
  • the detergent solution also comprises a preserving agent such as a didecyldimethylammonium salt, bis (aminopropyl) laurylamine, an isothiazolinone, benzyl alcohol, a phenoxy alcohol or sodium benzoate.
  • the isothiazolinone is advantageously chosen from methylisothiazolinone (MIT, MI), chloromethylisothiazolinone (CMIT, CMI, MCI), benzisothiazolinone (BIT), octylisothiazolinone (OIT, 01), dichlorooctylisothiazolinone (DCOIT, DCOI) and butylbenzisothiazolinone (BBIT) and mixtures thereof, preferably it is methylisothiazolinone.

  • hydrotrope refers to, but is not limited to, sodium para-toluenesulfonate and sodium xylenesulfonate.
  • the detergent solution further comprises one or more phosphorescent agents such as disodium 2,2 '- ([1,1'-biphenyl] -4,4-diyldivinylene) bis (benzenesulphonate) ( Tinopal® CBS sold by BASF (Ludwigshafen, Germany)) or optical brighteners such as Sera White PN commercialized by Dystar.
  • phosphorescent agents such as disodium 2,2 '- ([1,1'-biphenyl] -4,4-diyldivinylene) bis (benzenesulphonate) ( Tinopal® CBS sold by BASF (Ludwigshafen, Germany)) or optical brighteners such as Sera White PN commercialized by Dystar.
  • a phosphorescent agent makes it possible to visualize under UV light the surfaces treated by the nonwoven support. This makes it possible to verify the homogeneity of the treatment of the medical device by the nonwoven support impregnated with the detergent solution.
  • the two-part cleaning and disinfecting system according to the invention is particularly advantageous for cleaning and disinfecting objects having a hard surface, such as medical instruments and devices as well as working surfaces, in that it makes it possible to use a single type of non-woven support impregnated with a detergent solution for two distinct and complementary applications: as such to clean the object and after application of the disinfecting composition to disinfect the 'object.
  • Medical instruments and devices within the meaning of the present invention include endoscopes without an internal channel such as nasofibroscopes and transoesophageal, hemodialysis generators, ultrasonic probes and electronic thermometers.
  • a second object of the invention is the use of the two-part wipe system described above for cleaning and / or disinfecting objects having a hard surface, such as medical instruments and devices and surfaces. working.
  • the invention also relates to a method for cleaning and disinfecting an object having a hard surface, such as medical instruments and devices and work surfaces, comprising the following steps: a) Providing a cleaning and disinfection system two parts as defined above, comprising a first part comprising at least one nonwoven support impregnated with a detergent solution comprising a color pH indicator, and a second part comprising a container containing a disinfecting composition comprising at least one peracid;
  • step c) wiping the hard surface of said object previously wiped with the first nonwoven support with the nonwoven disinfectant support prepared in step c);
  • the support changes color because of the colorimetric reaction between the pH indicator of the detergent solution and the peracid of the disinfecting composition. For example, when the pH indicator is methyl red, the nonwoven support impregnated with the solution detergent alone is yellow and becomes pink when applying the disinfectant composition containing the peracid.
  • the application of the disinfecting composition comprising at least one peracid gives the nonwoven support a broad-spectrum biocidal action against bacteria, yeasts, molds, mycobacteria, naked and enveloped viruses and bacterial spores.
  • the present invention provides a two part cleaning and disinfection system that is easy to use and effective. In particular, it avoids the risks associated with the in situ formation of chemicals and thus minimizes the risk of insufficient disinfecting power.
  • the fact of starting from a nonwoven substrate impregnated with a detergent solution makes the system particularly versatile since only one type of nonwoven support can be used for two distinct and complementary applications. More particularly, the nonwoven support impregnated with the detergent solution may be used alone for cleaning an object having a hard surface without this cleaning being followed by a disinfection step.
  • Example 1 Preparation of the detergent compositions
  • the detergent solutions SI to S8 (pH 8), the formulas of which are given in Table 1, were prepared by adding a premix at a level of 1.5% by weight to the respective detergent solution.
