Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disinfecting cleaning agent and a disinfecting cleaning liquid used for cleaning medical equipment such as artificial dialysis equipment and peripheral equipment.

[0002]

2. Description of the Related Art An artificial dialysis apparatus is contaminated by body fluids such as blood and components thereof adhered during use. If the contamination is left untreated, it causes infection by bacteria and viruses, anaflux by heterologous proteins, and the like. Therefore, after use, it is necessary to remove the contaminants by washing and sterilizing to remove the danger.
In addition, contamination of the dialysate supply device or supply line may cause bacterial growth, which may cause bacterial infection or fever in patients due to endotoxin. In particular, recently, sodium bicarbonate was added for pH adjustment. Since dialysis fluid is widely used, calcium salts such as calcium carbonate precipitate and easily adhere to liquid contact parts such as pipes, which may cause troubles such as malfunction of the patient monitoring device. Removal of this stain is also required. Although the cause of this calcium salt is unknown, occasionally a large amount of an abnormally large precipitate, which is considered to be calcium carbonate, may adhere thereto. Furthermore, in the dialysis fluid discharge line, waste products transferred from the blood by dialysis adhere to the calcium salt in addition to the above-mentioned calcium salt, which is dirty and leads to reverse contamination during subsequent dialysis. Become.

Therefore, conventionally, in order to remove and sterilize the adhesion and contaminants in the dialysis apparatus and its peripheral devices as described above, generally, two-stage washing with an aqueous sodium hypochlorite solution and an acetic acid solution is generally performed. It is being done. In addition, a disinfecting detergent containing sodium hypochlorite, a sequestering agent and an anionic surfactant has been proposed as a device capable of performing one-step washing for the same purpose (Japanese Patent Laid-Open No. 4-1355).
No. 59, 7-233396, etc.).

[0004]

However, the above-mentioned conventional cleaning means using sodium hypochlorite and acetic acid is excellent in sterilization and disinfection, but has a poor ability to remove adhering components such as oils and fats. The effect is not sufficient, and there is a problem that the operation is complicated and requires a large amount of labor and time to perform the cleaning in two steps. In an actual medical practice, there is a margin of time for performing the two-step cleaning. Often there are no. In addition, the disinfecting detergent containing sodium hypochlorite and a sequestering agent and an anionic surfactant of the above-mentioned proposal is excellent in disinfecting effect and removing effect of body fluid components,
In addition to the inadequate ability to remove the large and large amount of deposits of the occasionally generated calcium salt, the decomposition of the sequestering agent by sodium hypochlorite progresses with time, resulting in a decrease in efficacy. There was a disadvantage that the washing solution could not be stored for a long time.

[0005] In view of the above situation, the present invention provides a strong disinfecting and cleaning effect by one-step cleaning as a disinfecting cleaning agent and a disinfecting cleaning solution used for cleaning medical equipment such as artificial dialysis equipment and peripheral equipment. It is an object of the present invention to provide a material which can easily remove even a large amount of deposited deposit of calcium salt and has excellent storage stability.

[0006]

Means for Solving the Problems In the course of studying to achieve the above object, the present inventors first paid attention to the fact that an acid is particularly effective in removing calcium salts. As a result of thorough research to elucidate the composition of a high-performance disinfectant cleaning agent in combination with the above, when a specific oxygen-based oxidizing agent component is used as a disinfectant, a powerful sterilization and disinfection effect is achieved by one-step cleaning. The present invention has been found to be capable of exerting an action of removing calcium salts, being capable of being stored for a long time as a disinfecting and cleaning solution, and being safe and easy to handle, and leading to the present invention.

[0007] That is, the disinfecting detergent according to claim 1 of the present invention is characterized by containing a monosulfate compound and an acid component. The oxygen denatures the cellular proteins of the microorganism by the oxygen, and at the same time, oxidizes and degrades the toxins produced by the bacteria to make them harmless, and at the same time, reduces the oxidation-reduction potential (hereinafter abbreviated as ORP) of the microorganism. Put it outside, and demonstrate excellent sterilizing action,
High calcium salt removal effect by acid is obtained, and monosulfate compound is stable in the presence of acid, so it does not cause germicidal disinfection action and calcium salt removal action over time, and generates harmful components. There is no danger of explosion, etc., and it shows safe and good storage stability.

According to a second aspect of the present invention, the monosulfate compound in the disinfectant cleaning agent of the first aspect is a triple salt comprising potassium monopersulfate, 1 mol of potassium hydrogen sulfate and 1 mol of potassium sulfate. The configuration is adopted. According to this configuration, the stability of the triple salt is good, so that the long-term storage property of the disinfecting cleaning liquid in the form of an aqueous solution is particularly good.

According to a third aspect of the present invention, the acid component in the disinfectant cleaning agent of the first or second aspect is succinic acid, acetic acid, citric acid, malic acid, glycolic acid, maleic acid, sulfamic acid, phosphoric acid, hydrogen sulfate. It adopts a configuration that is at least one selected from the group consisting of sodium and tartaric acid. In this configuration, sufficient calcium removal by acid can be exhibited, and ORP can be obtained at a general washing solution concentration.
Can easily be set to +900 mV or more, and since the metal is less corrosive to an acid, the corrosion accompanying the cleaning of the metal part to be cleaned is suppressed.

A fourth aspect of the present invention is the disinfectant cleaning agent according to any one of the first to third aspects, wherein the detergent contains a surfactant in addition to the peroxide monosulfate compound and the acid component. . According to this configuration, the surfactant improves the cleaning property against stains such as oils and fats,
Since the wettability of the cleaning liquid to the surface to be cleaned and the penetration into the inside of the adhered substance are enhanced, more excellent disinfecting cleaning performance is exhibited.

According to the fifth aspect of the present invention, since the disinfectant cleaning agent according to any one of the first to fourth aspects employs a powder mixture of contained components, the disinfecting detergent is simply dissolved in water. The above disinfectant can be supplied as a pack product in powder form that can be easily prepared.

According to a sixth aspect of the present invention, there is provided a disinfecting cleaning solution comprising an ORP in which a monosulfate compound and an acid component are dissolved in water.
Since a structure composed of an acidic aqueous solution of +900 mV or more is employed, sterilization properties based on ORP can be sufficiently exhibited.

According to a seventh aspect of the present invention, in the disinfecting cleaning solution of the sixth aspect, a structure is used in which a surfactant is dissolved together with the monosulfate compound and the acid component. In addition to the bactericidal property of the surfactant and the calcium salt removing property of the acid component, the above-mentioned action of the surfactant can be obtained.

[0014]

BEST MODE FOR CARRYING OUT THE INVENTION The disinfecting detergent according to the present invention contains a peroxide monosulfate compound and an acid component, and more preferably contains a surfactant together with both the components.
By providing medical components such as artificial dialysis machines and their peripheral devices as aqueous solutions in which these components are dissolved in water,
In addition to the sufficient sterilization and disinfection of the object to be cleaned, the removal of the contaminants such as body fluids such as blood and the components thereof and the deposits such as calcium salts can be performed efficiently and easily in a short time by one-step cleaning.

The above-mentioned persulfate monosulfate compound used in the present invention releases oxygen in the molecule as an oxidizing agent, which denatures microbial cell proteins and simultaneously oxidatively degrades toxins produced by bacteria. In addition to detoxification, the ORP is placed outside the range of microorganisms and exhibits excellent disinfecting and disinfecting action. However, since it is stable in the presence of the acid component used in combination, the time of the disinfecting and disinfecting action is reduced. It is characterized in that it does not cause a decrease, does not inhibit the action of removing the calcium salt by the acid component, and has no danger of generating harmful components and explosion.

Such a monosulfate compound may be a monosulfate alone such as potassium monosulfate (KHSO ₅ = potassium hydrogen peroxosulfate). Various composite compounds included as constituents are included. Among these peroxide monosulfate compounds, a triple salt composed of 2 moles of potassium monopersulfate, 1 mole of potassium hydrogen sulfate and 1 mole of potassium sulfate, that is, the following general formula: 2KHSO ₅ · KHSO ₄ · K ₂ SO _The compound represented by ₄ is recommended as a particularly suitable compound because it is obtained in a powder form, easily dissolved in water to form an acidic aqueous solution, and has good stability in the presence of an acid. In addition, as a commercially available product of such a triple salt, there is Oxon (trade name) manufactured by E.I.

An oxidizing agent capable of exhibiting a disinfecting function
There are oxygen type and chlorine type, but chlorine type
The oxidizing agent is stably present in an acidic region such as PH3 or less.
It is difficult to apply
Prepare a disinfectant cleaning solution to be used for one-stage cleaning.
Generates toxic chlorine gas, which is dangerous in handling
There is a problem. On the other hand, oxygen-based oxidizing agents
In addition to the nonsulfate compounds, a typical example is water peroxide
Sodium, sodium percarbonate, sodium perborate, persulfate
(Peroxodisulfate) etc., but hydrogen peroxide is stable
Explosion hazard due to lack of properties
Sodium oxalate is used as an acid because the aqueous solution is alkaline.
There is a problem with the combination of Persulfate is, for example,
Lium (K _TwoS_TwoO₈Stable powder without danger like)
Some of the powders are aqueous and the aqueous solution is slightly acidic.
Compared to the peroxide monosulfate compound used in the light,
Inferior in both bactericidal properties and calcium salt removal properties
It turns out that.

That is, the microorganism is +200 to +820 mV for facultative aerobic microorganisms and -700 to +100 mV for anaerobic microorganisms as the ORP. It is said that outside this region A, energy metabolism and respiration are inhibited, making it difficult to inhabit. However, as is clear from the figure, the ORP is +900 mV or more and 0 m below PH3.
Microorganisms cannot grow under any of the conditions below V. For example, in the case of potassium persulfate, the ORP in a 1% aqueous solution is +
As low as 610 mV, even if 1% citric acid is added to this aqueous solution, the ORP is about +800 mV as shown in the examples below, and the ORP cannot be set to +900 mV or more. In contrast, it has been found that the peroxide monosulfate compound has an ORP of 900 mV or more even in an aqueous solution having a low concentration of about 0.05%, and has a higher calcium solubility than persulfuric acid.

As the above-mentioned acid component used in the present invention, those having high solubility of calcium salt are preferable.
Mineral acids that are highly corrosive to metals, such as nitric acid, should be avoided, and those that can set the ORP at +900 mV or more at a normal cleaning solution concentration in combination with a monosulfate peroxide compound are desirable. Acid components satisfying such conditions include succinic acid, acetic acid, citric acid, malic acid,
Maleic acid, glycolic acid, sulfamic acid, phosphoric acid,
Sodium hydrogensulfate, tartaric acid and the like.
More than one species can be used in combination. Thus, succinic acid, acetic acid, citric acid, and malic acid are particularly preferable from the viewpoint of solubility of the calcium salt. Regarding other acid components, for example, the solubility of calcium salt in oxalic acid is too low, and the formic acid has an ORP of +900 mV in the cleaning solution.
These settings cannot be made, and all are unsuitable.

The disinfectant cleaning composition of the present invention contains the above-mentioned monosulfuric acid peroxide compound and an acid component as essential components, and it is more preferable that the composition contains a surfactant together with both components. That is, the surfactant imparts a function of removing dirt such as oils and fats, enhances the wetting of the cleaning liquid on the surface to be cleaned and the permeability of the inside of the attached matter, and thereby further improves the disinfecting and cleaning ability of the cleaning liquid. Fulfill.

The surfactant is not particularly limited, but is preferably, for example, paratoluenesulfonic acid and its salt, metaxylenesulfonic acid and its salt, alkyldiphenylether disulfonate, polyoxyethylene alkyl. Anionic surfactants such as sulfates, polyoxyethylene alkylphenyl sulfates, and alkylbenzene sulfonates; and nonionic surfactants such as polyoxyethylene alkylphenyl ether, polyoxyethylene alkyl ether, and polyoxyethylene polyoxypropylene Is mentioned.

Of these, from the viewpoint of the removability of fats and oils, three kinds of anionic surfactants of alkyl diphenyl ether disulfonate, polyoxyethylene alkyl phenyl sulfate and polyoxyethylene alkyl sulfate are particularly excellent. ing. In addition, para-toluenesulfonic acid and its salt and meta-xylene sulfonate have low foaming properties, so that they are suitable for a case where a device to be cleaned or a device for handling a cleaning liquid is likely to cause a problem due to bubbles, and The molecular weight is smaller than that of the surfactant, so that it can penetrate into the fine structure to exhibit good detergency, and has the advantage that it can be reliably removed from the fine structure by washing with water, particularly from the hollow fiber membrane. This is convenient for washing a dialysis line provided with an endotoxin removal filter.

In order to prepare a disinfecting cleaning solution, the above-mentioned peroxide monosulfate compound and an acid component and, if necessary, a surfactant may be dissolved in water so as to have a pH of 3 or less and an ORP + 900 mV or more. The concentration of each component in the disinfecting cleaning solution is about 0.01 to 1% by weight for a peroxide monosulfate compound, about 0.2 to 4% by weight for an acid component, and 0.05 to 0.5% for a surfactant. %. Then
Generally, a disinfecting detergent in the form of a powder mixture in which powders of these components are mixed in an appropriate ratio, or a disinfecting detergent in the form of a high-concentration liquid containing these components in an appropriate ratio, is commercialized in medical institutions. When used for disinfecting cleaning, the former powder mixture is dissolved in an appropriate amount of water, and the latter is concentrated with an appropriate amount of water to be used as a disinfecting cleaning liquid of a required concentration.

In order to prepare a disinfectant detergent in the form of a powder mixture, it is necessary to use a powdery component for each component, but the triple salt (trade name: Oxone) as a peroxide monosulfate compound
Is in powder form, and succinic acid, citric acid, malic acid, tartaric acid, maleic acid, sodium hydrogensulfate, sulfamic acid, and the like can be obtained as powdered products. In addition, since surfactants are generally liquid products, this liquid product is separated from the powder mixture of the above-described monosulfate peroxide compound and the acid component, and is added to water together with the powder mixture when preparing a disinfecting cleaning solution. You may do so. However, since powdery surfactants also exist, the use thereof enables the production of a disinfecting detergent in the form of a powder mixture containing a peroxide monosulfate compound and an acid component and a surfactant. Examples of such surfactant powder products include, for example, trade name L manufactured by BASF.
UTENSOL AT-50, LUTENSOL A
T-75, NSA-17 (trade name, manufactured by Sanyo Kasei Kogyo Co., Ltd.), Lionol PF-78 (trade name, manufactured by Lion Corporation), PRONON 208 (trade name, manufactured by NOF Corporation), all of which belong to nonionic surfactants are commercially available. Have been.

[0025]

The present invention will be specifically described below with reference to examples. In addition,% in the following means weight%.

[Production Example 1 of Disinfecting Cleaning Solution] Peroxide monosulfate compound (2KHSO ₅ · KHSO ₄ · K ₂ SO ₄ ..., Oxone) and potassium persulfate (K ₂ S ₂ O ₈ )
Was used as a disinfectant and dissolved in water to prepare aqueous solutions of various concentrations. In addition, 0.05% of the peroxide monosulfate compound
A 1% aqueous solution of 1% aqueous solution and 1% aqueous solution of potassium persulfate were also prepared at the same time. The results of measuring the PH and ORP of these aqueous solutions and the amounts of CaCO ₃ dissolved by aqueous solutions of 0.2% and 1% of the bactericide are shown in Table 1 below. The amount of CaCO ₃ dissolved was 0.1% at a fungicide concentration of 0.2% by adding calcium carbonate powder to 1 liter of an aqueous solution.
1 g each, and 0.5 g at the same 1%, were added sequentially, and each time the mixture was added, the mixture was stirred with a magnetic stirrer, and the addition amount until the turbidity due to the insoluble particles did not disappear was integrated.

[0027]

[Table 1]

From the results shown in Table 1, it can be seen that the aqueous solution of the monosulfate compound has an ORP of +900 mV even at a concentration of 0.05%.
As described above, it can be seen that CaCO ₃ has solubility. On the other hand, an aqueous solution of potassium persulfate has an ORP of +610 mV at a concentration of 1%, and does not reach ORP + 900 mV even with a composition containing 1% of citric acid.
It is apparent that O ₃ has little solubility and is inferior as a disinfectant to be used in a disinfecting cleaning solution as compared with a peroxide monosulfate compound.

[Preparation Example 2 of Disinfecting Cleaning Solution] Persulfuric acid monosulfate compound (Oxone) as a bactericide, succinic acid, acetic acid, citric acid, malic acid, maleic acid, glycolic acid, sulfamic acid as an acid component Disinfecting cleaning solutions having various disinfectant concentrations and acid component concentrations were prepared using mixtures of phosphoric acid, sodium hydrogen sulfate, tartaric acid, oxalic acid, and citric acid-malic acid at a weight ratio of 1: 4, respectively. The results of measuring the amounts of dissolved PH, ORP, and CaCO _{3 in} these cleaning solutions are shown in Tables 2 and 3 below together with the concentrations of the components.

[Table 3]

As is clear from the results of Tables 2 and 3, when the acid component concentration is 0.2%, citric acid, maleic acid, sulfamic acid, phosphoric acid, sodium hydrogen sulfate,
In the citric acid-malic acid mixture, the concentration of the peroxide monosulfate compound is 0.01%, and in the succinic acid, acetic acid, malic acid, glycolic acid, and tartaric acid, the concentration of the peroxide monosulfate compound is 0.0%.
At 5%, it becomes a disinfecting cleaning liquid of ORP + 900 mV or more. In addition, the solubility of the calcium salt is determined by succinic acid> acetic acid> citric acid, malic acid, citric acid-malic acid mixture>
Maleic acid> glycolic acid> sulfamic acid> phosphoric acid>
It is understood that sodium hydrogen sulfate> tartaric acid is larger in the order, and succinic acid, acetic acid, citric acid, and malic acid are particularly suitable. Also, the higher the concentration of the peroxide monosulfate compound, the more O
It is suggested that as the RP increases, the solubility of the calcium salt slightly increases. However, when oxalic acid is used as the acid component, it cannot be set to ORP + 900 mV or more, and the solubility of the calcium salt is hardly exhibited.

[Preparation Example 3 of Disinfectant Cleaning Solution] A monosulfate compound (Oxone, trade name) was used as a bactericide in an amount of 0.0
1% or 0.02% concentration, sulfamic acid, succinic acid, citric acid, malic acid, acetic acid, citric acid as acid component
A disinfecting cleaning solution was prepared with a malic acid mixture (same as above) at a concentration of 0.2% for each and the following surfactants a to l at a concentration of 0.03% for each, and the removability of oils and fats by each disinfecting cleaning solution was examined.
The results are shown in Table 4 below together with the combinations of the components. The removal of oils and fats was performed by dropping 10 μl of oleic acid (oils and fats) colored with Sudan III onto a slide glass and indoors.
After leaving the slide glass for 6 hours, the slide glass was immersed in a disinfectant cleaning solution, and the time (min) until the oil droplets disappeared from the glass surface was shown as the removal time.
