DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage channel for dental medical equipment, particularly to a vacuum line, which suppresses slime caused by the propagation of bacteria and fungi, thereby communicating with the vacuum line and the vacuum line. The present invention relates to a slime control agent capable of suppressing generation of off-flavors and odors generated from a spitton portion.

[0002]

2. Description of the Related Art Dental medical devices (units) have a drainage channel such as a spitton portion for rinsing mouth and saliva and a vacuum line, and saliva, blood, and prosthetic material waste discharged from a patient's mouth are generated by these. It is discharged through drains.

[0003] However, microorganisms propagate using the discharged saliva, sputum, blood and prosthetic material debris as nutrients, and as a result they are spoiled. As a result, organic deposits (slime) are generated in the drainage channel, and a bad smell is generated. The odor generated by the slime is not only unpleasant for the patient to be treated, but also sometimes causes troubles such as the slime decreasing the flow rate in the drainage channel. In addition, these slimes are a hotbed of various bacteria including pathogenic bacteria, which is a problem in view of the dental practice.

Although this slime is similar in composition to slime found in kitchens of ordinary households, etc., the drainage channel for dental medical equipment has a complicated structure and is usually easily cleaned because it is a closed system. The structure cannot be performed.

[0005] Therefore, a method of installing an ionizer in a drain pipe to generate a kind of electrolyzed water and sterilize it by using the same.

No. 7341), a method in which a drainage storage section is provided and ozone is introduced therein (Japanese Utility Model Application Laid-Open No. 62-72197), and a method of installing a germicidal lamp (Japanese Utility Model Application No. 05-48915).
However, dental medical devices are designed compactly and precisely, and it is difficult to add them to existing devices.

As a detergent, there has been proposed an agent (JP-A-10-8189) in which granular sodium percarbonate is a main agent and granular sodium hydrogencarbonate is an auxiliary. However, it is premised to dissolve and use when sucked into the vacuum line, which not only increases the labor, but also causes the vacuum line to have a small tube diameter if there is dissolved residue. In some cases, this caused the blockage.

Acrylic resin, aluminum, brass, and the like are used for spittoon drainage channels and the like, and may be coated with chrome or tin, or may be specially painted. Liquid bleaching detergent
(Sodium hypochlorite detergent and hydrogen peroxide detergent)
Thus, although easy to use, there is a possibility that corrosion or discoloration may occur in the material used.

BEST MODE FOR CARRYING OUT THE INVENTION The slime-controlling agent for a vacuum line of a dental medical device of the present invention has an appropriate viscosity, that is, 25.
2 cp (0.002 Pa · s) to 20 ° C. viscosity
It is characterized by being composed of a liquid medicine of 0 cp (0.2 Pa · s). The optimum viscosity of the drug varies depending on the vacuum line vacuum pressure of the dental medical equipment used, the usage, the time of use, and the region of use, but the viscosity at 25 ° C. is 2 cp (0.002 Pa · s) to 200 cp (0.2 P).
a · s) desirably 3 cp (0.003 Pa · s) to 1
50 cp (0.15 Pa · s), more preferably 5 cp
(0.005 Pa · s) to 100 cp (0.1 Pa · s)
In the case of s), the spreadability and dispersibility of the drug on the wall of the drainage channel can be ensured, and the antibacterial agent contained in the liquid drug can be evenly distributed on the inner peripheral surface of the drainage channel, thereby increasing the propagation of germs. Efficient suppression can be achieved, and as a result, odor generated from the spitton portion can be suppressed.

The viscosity of the drug is 2 cp (0.002 Pa ·
If it is lower than s), the antibacterial agent in the medicine will flow away before spreading on the drainage wall, and the viscosity will be 200 cp (0.2
If it is higher than Pa · s), not only does the drug not reach every corner of the drainage channel, but if it is extremely high, it may cause blockage, which is not preferable.

For example, consider a case in which 50 mL of a drug is sucked from a vacuum line of a general dental medical device, and 100 mL of water is sucked again after 1-2 minutes.
When the viscosity of the medicine at 25 ° C. is less than 2 cp due to the suction force of the vacuum line, the medicine flows off without spreading to the side surface of the drainage channel. On the other hand, if it exceeds 200 cp, the fluidity is poor and the drug has air bubbles,
Unevenness occurs on the drain line wall including the vacuum line and the storage part ahead. Furthermore, if the viscosity becomes extremely high, the fluidity will be lost at all, and although it will be sucked somehow in the vacuum line, it will gradually accumulate in the storage part where the flow velocity is decreasing, and in addition, the prosthetic material waste etc. Instead, it causes blockage.

[0016] Thickeners are usually used to impart the appropriate viscosity to the drug. As such a thickener, a thickener such as a cellulose-based, polycarboxylic acid-based, polyamino acid-based, or polyvinyl alcohol-based thickener can also be used. For these reasons, polyethylene glycol is desirable. Among them, the average molecular weight is 300 to 200 from the viewpoint of solubility in water, viscosity when dissolving in water, and hygroscopicity during storage of raw materials.
Desirably, polyethylene glycol of 4000 to 8000 is easy to use.

The antibacterial agent used in the slime control agent for the vacuum line of the dental equipment of the present invention may be any antibacterial agent which is known as an antibacterial agent which is highly effective against various germs appearing in general home kitchens and the like. Any kind of liquid bleaching detergent (sodium hypochlorite detergent or hydrogen peroxide detergent) that may cause corrosion or discoloration of the water distribution pipe or the like is not preferred. In addition, when there is a possibility that pathogenic microorganisms may be present in the vicinity of the medical device, it is also possible to separately add an effective bactericide against the pathogenic microorganisms and an antibiotic or antiviral agent to the antibacterial agent used in the present invention. I can do it.

The antibacterial agents preferably used in the present invention include, specifically, 2-n-octyl-4-isothiazolin-3-one, 5-chloro-2-methyl-4-isothiazolin-3-one, 2-methyl-4-isothiazolin-3-one, 2-bromo-2-nitropropane-
1,3-diol, 2,2,4'-trichloro-2'-hydroxydiphenyl, hexadecylpyridinium chloride, hexadecylpyridinium bromide, diisobutylphenoxyethoxydimethylbenzylammonium chloride, benzammonium chloride, 1,2-
Benzisothiazolone-3, Nn-butyl-1,2-
Benzisothiazolone-3,3,4,4'-trichlorocarbanilide, bisdimethylthiocarbamoyl disulfide, 1-1 '-(hexamethylenebis [5- (4-chlorophenyl) biguanide]) digluconate, bis (p- Chlorophenyldiguanide) hexane dihydrochloride, poly (hexamethylene biguanide) hydrochloride, pyridinethiol-1-oxide sodium salt, zinc bis (2-pyridylthio-1-oxide), and the like. These can be used alone or in combination of two or more.

The liquid medicine in the present invention is preferably substantially neutral, that is, one having a slightly acidic to almost neutral pH value. By using such a substantially neutral medicine, it can be used in a drainage channel. It does not corrode or discolor the piping and other materials used.

When the liquid medicine in the present invention is sucked by the vacuum line, the pressure is reduced by the vacuum line, and flows into the reservoir at a high flow rate. For this reason, generation of bubbles in the storage section may be a problem. Therefore, it is preferable to add an antifoaming agent to the drug. Specific examples of such an antifoaming agent include a silicone-based antifoaming agent and a surfactant-based antifoaming agent.

Further, a surfactant as a cleaning component can be added to the liquid drug in the present invention. The surfactant used is not particularly limited, but PO (propylene oxide) & EO (ethylene oxide) block polymer type, PO & EO alkyl ether type, higher alcohol type, POE (polyoxyethylene) alkyl ether phosphoric acid type and the like can be used. . Further, if necessary, a corrosion inhibitor such as benzotriazole, a fragrance, a dye, a chelating agent, an antifoaming agent, and the like can be added.

As a method of using the slime control agent for a vacuum line of a dental medical device according to the present invention, an appropriate method according to the type of the dental medical device, its use, the time of use, the region of use, and the like is appropriately selected. However, slime control agents for dental equipment vacuum lines are usually used after the end of the day at the dentistry site, and because it is a daily work, there is no need for special work / operation, A simple method is desirable. Specifically, a simple method of sucking the slime control agent from a vacuum line and then sucking water can be exemplified. According to the method for controlling slime according to the present invention, it is possible to control the slime by sucking water weighed to a certain amount by the measuring cup from the vacuum line and sucking water later, so that the operator's hand is not particularly troublesome. .

The slime control agent of the present invention does not have the function of instantly decomposing and cleaning the slime which has already adhered at once, unlike a sodium hypochlorite-based cleaning agent, but suppresses the growth of bacteria. Since the generation of new slime is suppressed, the slime that already exists can be gradually washed away and the slime existing in the drain passage can be gradually but removed, in combination with the function of the surfactant of the drug. The closing time at the dental care site is from the evening to the evening, and there is considerable time from the beginning of the morning to the beginning of the morning, and immediate effects such as sodium hypochlorite cleaning agents are not necessarily required for practical use. is not. In addition, when there are many deposits and various germs in the initial stage of use, the used amount can be 2 to 3 times the normal used amount. In addition, other cleaning agents such as a sodium hypochlorite-based cleaning agent can be used as needed, for example, at the beginning of use.
