[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to ozone gas to be injected into a udder for treating bovine mastitis, which ozone gas produced by an ozone generator is transferred to a desired place, where it is fed to the cow. The present invention relates to ozone gas processed so that it can be used for treating mastitis, and a method of treating mastitis in cattle using this gas.

[0002]

2. Description of the Related Art Conventionally, the treatment of bovine mastitis has mainly been conducted with the administration of antibiotics, but this treatment involves injecting the antibiotics into the udder for several days or longer, and further needs the administration. Depending on the method, antibiotics may be injected intramuscularly, intravenously, or intraarterially to suppress the growth of pathogenic bacteria in the breast, lacunae, and nipples, and to cure mastitis. there were.

However, the above-mentioned treatment with antibiotics has many problems in addition to the high cure rate and therapeutic effect. That is, (1) drug costs are high. (2) A long treatment period is required. (3) Expert knowledge and diagnostic technology are required for drug selection, and advanced technology is required depending on the drug administration route. (4) Antibiotics have only the effect of suppressing recent growth,
In order to supplement the natural healing power of cattle, an expensive drug is required separately. (5) Since the amount of injected antibiotics is very small, it is difficult to reach deep inside the breast and tissue damage due to stimulation is likely to occur. (6) It is not related to the treatment of productive toxins of infectious microorganisms and free radicals generated by inflammation in inflamed tissues. (7) Proper use of antibiotics causes probiotic resistance and bacterial dysplasia. (8) Antibiotics remain in the product, and the milk of treated cows must be discarded until the residue is no longer visible, with losses. (9) Since antibiotics are required indicators, they can be used only under the direction of a veterinarian. (10) At the time of treatment, it is necessary to treat the diseased cow while it is close to the diseased cow, and the sudden noise of the cow may put the worker at risk. There are problems such as.

Therefore, recently, ozone is injected into the udder from the nipple mouth of the udder without using antibiotics, and the ozone is supplied to the pathogenic microorganisms and their tissues present in the udder, the cistern and the nipple. The treatment method to act has come to be performed.

As an apparatus for the above-mentioned treatment using ozone, the ozone injecting apparatuses of Japanese Patent No. 3022323 and Japanese Patent No. 3022341 have been proposed. Of these devices, the former is provided with a switching valve in the gas flow path of an ozone generator connected to an oxygen cylinder or an air compressor, and the switching valve has an ozone decomposer and a tip end inserted into the cow's teat mouth. Is connected to a gas introduction tube equipped with an ozone injecting tube, and the latter receives ozone supplied from an oxygen supply device to generate ozone and discharges the ozone while removing ozone from the ozone generation device. A flow rate control valve that controls the flow rate of ozone and a discharge control valve that discharges excess ozone to the outside are provided in the flow path, and the flow rate control valve is equipped with an ozone injection tube for injecting into the cow's udder at the tip. Connect an ozone introduction tube, and to the ozone introduction tube,
A pressure detection device for detecting the pressure of ozone injected into the cow's udder is provided, and the flow control valve is controlled by the value detected by the pressure detection device, and excess ozone is discharged from the discharge control valve. It was done like this.

When treating mastitis of cattle using the above ozone injecting device, the gas volume of ozone + oxygen used for one treatment is 0.1 to 3 liters, and the concentration of ozone gas is 1 to 3 liters. 50 mgO ₃ is desirable, which can solve the above-mentioned problems of the conventional treatment with antibiotics, but it cannot be said that it is still widely used. The reason is that in order to treat mastitis of cattle using ozone gas, it is necessary to purchase the ozone injection device according to the above-mentioned patent and install it at a predetermined place, but when it is not possible to confirm the therapeutic effect etc. This was because there was no choice but to buy an ozone injection device in Japan.

The inventors of the present invention recognize that the rancher or the like has a therapeutic effect on the mastitis of cattle using ozone gas, so that the place where the ozone gas obtained by the ozone generator is used (the site of the ranch etc. is used). ), And planned to use it clinically for the treatment of bovine mastitis, but ozone gas deteriorates rapidly at room temperature, decomposes into oxygen in a short time, and is transferred in the ozone gas state. It was impossible to carry out this plan because it was considered impossible.

[0008]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional techniques, and by taking measures to delay the deterioration rate of ozone gas produced by an ozone generator or the like, the ozone gas is effectively transferred to the destination. It is an object of the present invention to provide an ozone gas that can be used and a method for treating bovine mastitis using this gas.

[0009]

The constitution of the ozone gas of the present invention made for the purpose of solving the above-mentioned problems is such that the ozone gas obtained from the ozone generator is housed and sealed in an airtight container, which is -10 ° C. or less, It is preferably characterized in that it is transferred to a place of use in a state of being cooled to -18 ° C or lower.

Since the above-mentioned ozone gas is cooled to -10 ° C or lower, preferably -18 ° C or lower, it is not decomposed and deteriorated in a short time. In addition to the bactericidal effect by itself, a synergistic effect of the therapeutic effect by cooling the breast, that is, the affected area can be obtained.

That is, the inventors of the present invention have conducted various studies on the transfer of the ozone gas obtained by the ozone generator to a place away from the ozone gas production site without deterioration, and as a result, the deterioration of the ozone gas In order to slow down the speed, it is known that ozone gas may be contained in a closed container, and this may be held at a temperature of -10 ° C or lower, preferably -18 ° C or lower, and transferred in this state, and the present invention has been completed. I did.

BEST MODE FOR CARRYING OUT THE INVENTION Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing the deterioration rate of ozone gas when cooled to −18 ° C., FIG. 2 is a diagram showing the deterioration rate of ozone gas at room temperature <30 ° C., and FIG. 3 is for injecting the ozone gas of the present invention into cow udders. 3 is a system diagram showing an example of the apparatus of FIG.

In the present invention, an experiment was conducted for the purpose of storing ozone gas obtained by a known ozone generator (not shown). First, when the degree of deterioration of the ozone gas was measured at room temperature (30 ° C.), the ozone concentration became 0 in about 24 hours (1 day) as shown in FIG. 2, whereas the same as in the above example. Ozone gas stored in an airtight container, for example, in a freezer and cooled to −18 ° C. was found to have about 35% ozone remaining after 5 days, as shown in FIG. It was This means that if ozone gas is kept at -18 ℃, it can be stored for 5 days, or
This shows that it can be used for transfer.

Therefore, the ozone gas of the present invention cooled to -10 ° C. or lower, preferably -18 ° C. or lower, as described above, has little deterioration even if it is transferred to a place distant from its production site over time, or Since it takes a long time to deteriorate, it can be used by injecting it into the udder for treating mastitis of cattle by using an appropriate ozone gas injecting means at the place of transfer.
The example will be described below.

Although not shown, the simplest injection means is to store the ozone gas of the present invention in a flexible container with a main stopper.
The rear end of an ozone gas introduction tube having an ozone injection tube connected to the tip is connected to the main stopper part, and the usage pattern is to insert the injection tube into a cow's udder to open the main stopper, and put the container into a human hand or the like. Ozone gas contained in the breast is injected from the injection tube through the introduction tube by applying a pressing force. When the ozone gas is stored in the flexible container, the container is stored in a freezer or the like, cooled, and transferred to the place of use in that state.

On the other hand, FIG. 3 is a system diagram of an example of the ozone injecting device of the present invention in which the ozone gas of the present invention is injected into a cow's udder by an ozone injecting device.
It is a closed container containing the cooled ozone gas and is equipped with a main stopper 1a. Reference numeral 2 is an ozone gas discharge control valve, 3 is an ozone gas flow rate control valve, 4 is a pressure gauge, 5 is an ozone injection pipe connected to the tip of an ozone introduction tube 6, and 7 is a check valve provided in front of the injection pipe 5. , 8 are cow udders into which the injection tube 5 is inserted, and the check valves 7 of the container 1 to the injection tube 5 are sequentially connected by the introduction tube 6.

Here, the discharge control valve 2 is for opening the ozone gas to the outside when the pressure detected by the pressure gauge 4 exceeds a predetermined pressure. Also, the check valve 7
Prevents the milk stored in the milk tank of the breast 8 from flowing backwards,
This is for preventing the inside of the ozone gas guide tube from being contaminated by the backward flow of milk.

The ozone injecting tube 5 is a hollow tube having a thickness that can be inserted into a cow's teat mouth, and a large number of fine ozone ejecting holes are formed at the tip of the tube, and a gas filter is provided if necessary. Sometimes used.

-10 ° C or less contained in the closed container 1,
Desirably, the ozone gas cooled at −18 ° C. or less is injected into the breast 9 through the introduction tube 6 and the ozone injection tube 8. This injection is performed by applying a pressure to the container 1 by appropriate means, so if the pressure gauge 4 detects that the pressure of the ozone gas injected into the breast 8 has risen and reached a predetermined pressure, At the same time as the flow control valve 3 is closed and the discharge control valve 2 is opened, the pressurization of the container 1 is stopped and the main tap 1a of the container 1 is closed.

In this way, when the cooled ozone gas contained in the closed container 1 is injected into the cow's udder, the infected milk in the milk tank can be efficiently aerated to the ozone gas. Since the inside of the milk tank is cooled by the cooled ozone gas, the sterilizing effect of the ozone gas and the cooling effect of the affected part by the gas synergistically act on the mastitis of cattle.

In the injection of the cooled ozone gas, the volume of gas injected at one time is preferably about 0.1 to 3 liters. This is because the effects of sterilization and cooling are dilute when the amount is 0.1 liter or less, and the breast is overloaded when the amount is 3 liter or more.

The concentration of injected ozone gas is 0.1 to 50 mgO ₃ /
L is preferred. When the concentration is 0.1 mgO ₃ / liter, ozone is decomposed immediately after injection to dilute the bactericidal effect, and when it is 50 mgO ₃ / liter or more, the concentration is too high, which is preferable for living tissues. This is because there is a high possibility that it will not work.

[0023]

Industrial Applicability The present invention is as described above, and ozone gas is contained and sealed in a highly airtight container made of synthetic resin such as vinyl, which is -10 ° C or lower, preferably -18 ° C.
It will be transferred to the destination while it is stored in a freezer cooled to ℃ or below and used for treatment of mastitis in cattle, so even if the concentration of ozone gas decreases during transfer storage, it will be transferred or stored for about 5 days. Since 35% of ozone gas remains without being decomposed, it can be used as it is for the treatment of mastitis in cattle, and therefore, the spread of the method for treating mastitis using ozone gas can be promoted.

As a method for treating mastitis before the discovery of antibiotics, a method of cooling the affected area was adopted, but the ozone gas of the present invention is cooled to -18 ° C in the examples, By injecting this into the udder, a synergistic effect of sterilizing effect of ozone and cooling of the affected part can be achieved, and the therapeutic effect of bovine mastitis can be further enhanced.
