DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] Fig. 1 is a perspective view of an ozone bubbling device for improving dermatitis (hereinafter also referred to as an ozone bubbling device) 100. As shown in Fig. 1, the device has an ozone generating unit 10 that generates a gas containing ozone, a bathtub unit 20 that is formed so as to be able to store water, and an ozone supplying unit 30 that supplies the gas containing ozone generated by the ozone generating unit 10 to the water stored in the bathtub unit 20.

[0018] The ozone generating unit 10 is a device that generates a gas containing ozone and sends the gas to the ozone supplying unit 30.

[0019] The bathtub section 20 has a structure that allows the affected area with dermatitis to be immersed in the water stored in the bathtub section 20. In this embodiment, the bathtub section 20 is formed in a box shape. The bathtub section 20 may be, for example, a water tank, a bathtub, etc., as long as it allows the affected area to be immersed in the stored water and can accommodate the ozone supply section 30. Moreover, the bathtub section 20 is not limited to being box-shaped, and may be bag-shaped.

[0020] The ozone supplying unit 30 is connected to the ozone generating unit 10 by a connecting member 40. The ozone supplying unit 30 supplies the air containing ozone sent out from the ozone generating unit 10 to the inside of the bathtub unit 20.

[0021] The connection member 40 is a piping member that connects the ozone generation unit 10 and the ozone supply unit 30. The connection member 40 may be any member that serves as a passage for gas, and is not particularly limited, but for example, a ring-shaped rubber hose can be used.

[0022] Fig. 2 shows the configuration of the ozone generation unit 10. As shown in Fig. 2, the ozone generation unit 10 has a housing 11. The housing 11 is formed, for example, in a box shape.

[0023] The housing 11 houses a pump 12 that takes in air from outside the housing 11 and discharges the pressurized air. The pump 12 receives an external power supply and discharges a fixed amount of air.

[0024] The housing 11 also contains an ozone generator 13 that generates ozone from air containing oxygen. The ozone generator 13 is, for example, a silent discharge type device that applies a high voltage to air containing oxygen to cause discharge, thereby generating (producing) ozone gas.

[0025] The ozone generator 13 is not limited to a silent discharge type device, but may be, for example, an electrolysis type device or an ultraviolet lamp type device.

[0026] The ozone generator 13 is connected to the pump 12 by a connection member 50. The connection member 50 is a piping member that connects the ozone generator 13 and the pump 12. The connection member 50 may be any member that serves as a passage for gas, and is not particularly limited, but for example, a ring-shaped rubber hose can be used.

[0027] Therefore, the ozone generating unit 10 can generate a gas containing ozone by mixing the ozone generated by the ozone generator 13 and the air sent out from the pump 12.

[0028] In addition, the ozone generator 13 is connected to a connection member 40. Therefore, the ozone generation unit 10 can send out a gas containing ozone to the ozone supply unit 30 via the connection member 40.

[0029] The ozone generator 13 has a timer (not shown). The ozone generator 13 may generate ozone according to the time counted by the timer. For example, when the ozone bubbling device 100 is operated for a predetermined time, the time for which the ozone generator 13 is operated may be controlled by the timer.

[0030] Incidentally, the control of the operation of the ozone generator 13 is not limited to such a timer, but may be, for example, a detector for detecting the ozone concentration in the bathtub section 20, and may be controlled according to the ozone concentration in the bathtub section 20. In other words, the ozone concentration of the air sent out from the ozone generator 10 may be adjusted according to the ozone concentration in the bathtub section 20.

[0031] The housing 11 may be provided with, for example, switches (not shown) for switching the operation of the pump 12 and the ozone generator 13 ON or OFF, and a power supply unit (not shown) for supplying power to the ozone bubbling device 100. The housing 11 may also be provided with an adjustment button for adjusting the airflow rate of the pump 12.

[0032] It is preferable to provide an air vent (not shown) that can take in air from outside the housing 11 into the inside of the housing 11. It is preferable to provide a filter in the air vent to remove impurities such as dust in the air.

[0033] Fig. 3 shows a plan view of the ozone supplying unit 30. As shown in Fig. 3, the ozone supplying unit 30 has a connecting part 31 formed so as to be connectable to a connecting member 40, and a releasing part 32 connected to the connecting part 31 and capable of releasing a gas containing ozone.

[0034] The connection part 31 is formed of a flexible tubular member such as a rubber hose. The connection part 31 has a tip part 31a connectable to the connection member 40 and a base part 31b connectable to the release part 32.

[0035] The release section 32 is formed in a rectangular plate shape. The release section 32 has a plurality of supply sections 33 capable of supplying the ozone-containing gas sent from the connection section 31 on one surface (upper surface).

[0036] Each of the supply units 33 is formed in a hollow cylindrical shape. Each of the supply units 33 is arranged on one surface at intervals. In this embodiment, each of the supply units 33 is arranged in 7 rows and 10 columns.

[0037] Fig. 4 shows an enlarged plan view of the discharge section 32. As shown in Fig. 4, four through holes 34 penetrating one surface of each of the supply sections 33 are formed. Therefore, the internal space of the discharge section 32 communicates with the outside of the discharge section 32 via the four through holes 34.

[0038] The adjacent supply units 33 are connected to each other by a plurality of pipes 35. The pipes 35 are connected to the base ends 31a of the connection units 31. Therefore, when the gas containing ozone is sent out from the connection unit 31, the gas passes through the pipes 35 and is released from the through holes 34 of the plurality of supply units 33.

[0039] In addition, a fixing member (not shown) capable of fixing the discharge section 32 to the bottom surface of the bathtub section 20 may be provided on the surface (bottom surface) behind the front surface of the discharge section 32. For example, a suction cup, a magnet, double-sided tape, a hook-and-loop fastener, etc. may be used as the fixing member.

[0040] A description will now be given of a dermatitis remedy method using the above-described ozone bubbling device 100. Fig. 5 shows the steps of the dermatitis remedy method. As shown in Fig. 5, a storing step is performed in which water is stored in the bathtub section 20 of the ozone bubbling device 100 (step S01).

[0041] In step S01, water may be stored in the bathtub section 20 with the ozone supplying section 30 placed at the bottom of the bathtub section 20. The amount of water stored is not particularly limited as long as it is a sufficient amount when the affected area is immersed in the water. In addition, from the viewpoint of supplying gas containing ozone to the water, it is preferable that the water is stored to at least cover the ozone supplying section 30. The water is not limited to cold water and may be adjusted to an appropriate temperature.

[0042] A supply step is carried out in which ozone-containing gas is supplied from ozone supply unit 30 to the water stored in bathtub unit 20 (step S02).

[0043] In step S02, a switch disposed in the housing 11 of the ozone generation unit 10 is turned on to operate the pump 12 and the ozone generator 13. When the pump 12 and the ozone generator 13 are operated, a gas containing ozone is sent from the ozone generation unit 10 to the ozone supply unit 30 via the connection member 40.

[0044] The ozone supplying section 30 discharges the ozone-containing gas sent from the ozone generating section 10 from the discharging section 32. When the ozone-containing gas is supplied to the water, the ozone-containing gas is supplied until the ozone concentration reaches a predetermined level. When the ozone is bubbled into the water, the concentration of hydrogen peroxide generated based on the ozone is preferably 0.010 to 0.100 ppm, more preferably 0.030 to 0.070 ppm, and even more preferably 0.034 to 0.068 ppm.

[0045] There is no established method for measuring the amount of ozone contained in water when ozone is bubbled into the water. On the other hand, it is possible to measure the amount of hydrogen peroxide derived from the ozone. Therefore, the ozone content of water is estimated by measuring the hydrogen peroxide content of water. Academically, it is believed that water contains an amount of ozone equal to or greater than the amount of hydrogen peroxide derived from ozone.

[0046] The amount of hydrogen peroxide can be measured using, for example, an AS ONE spectrophotometer ASV11D-H. When the ozone concentration (hydrogen peroxide concentration) in the water reaches a predetermined concentration, it is advisable to control the amount of ozone supplied in order to adjust the above-mentioned ozone concentration (hydrogen peroxide concentration).

[0047] An immersion step is performed in which an affected part of an animal (excluding humans) with dermatitis is immersed in water in the bathtub section 20 (step S03).

[0048] The time for which the affected area is immersed in water may be changed depending on the ozone concentration of the water and the condition of the skin of the affected area. For example, the time for which the affected area is immersed in water may be 1 to 60 minutes, preferably 5 to 30 minutes, and more preferably 10 to 20 minutes.

[0049] If the affected area is located in a part of the body where it is difficult to keep the affected area immersed in water, such as the head, water containing ozone gas may be sprayed onto the affected area. For example, water containing ozone gas may be sprayed onto the affected area using a shower, a bucket, or the like.

[0050] The method for improving dermatitis of the present invention is particularly effective against allergic dermatitis and seborrheic dermatitis.

[0051] As described above, according to the ozone bubbling device 100 of the present invention, it is possible to supply gas containing ozone while bubbling the water stored in the bathtub section 20. As a result, it is possible to make the water stored in the bathtub section 20 contain ozone.

[0052] Furthermore, according to the dermatitis improvement method and skin condition improvement method of the present invention, the user can improve dermatitis and skin condition by immersing the affected area in water stored in the bathtub section 20. EXAMPLES

[0053] [Test Example 1] (Verification of the effect on allergic dermatitis) We tested its effectiveness against allergic dermatitis suffered by Maltese dogs.

[0054] The affected area of ​​allergic dermatitis was periodically immersed for 10 to 20 minutes in the dermatitis improving ozone bubbling device 100, and the progress of the affected area was observed. The concentration of ozone gas generated by the ozone bubbling device was set to 1.25 to 1.50 ppm.

[0055] Fig. 6 shows the condition of the affected area (right side of the neck) before treatment with the ozone bubbling device 100 for improving dermatitis. Fig. 7 shows the condition of the affected area (right side of the neck) after the first treatment with the ozone bubbling device 100 for improving dermatitis. Fig. 8 shows the condition of the affected area (right side of the neck) after the second treatment with the ozone bubbling device 100 for improving dermatitis. Fig. 9 shows the condition of the affected area (right side of the neck) after the third treatment with the ozone bubbling device 100 for improving dermatitis. The numbers in the figures indicate the date and time when the images were taken.

[0056] As shown in Figures 6 to 9, the area of ​​the allergic dermatitis on the right side of the neck narrowed with each treatment, which confirmed that the symptoms were alleviated. In addition, the gradual appearance of hair around the affected area was confirmed after treatment.

[0057] Fig. 10 shows the state of the affected area (caudal abdomen) before treatment with the ozone bubbling device 100 for improving dermatitis. Fig. 11 shows the state of the affected area (caudal abdomen) after the first treatment with the ozone bubbling device 100 for improving dermatitis. Fig. 12 shows the state of the affected area (caudal abdomen) after the second treatment with the ozone bubbling device 100 for improving dermatitis. Fig. 13 shows the state of the affected area (caudal abdomen) after the third treatment with the ozone bubbling device 100 for improving dermatitis. The numbers in the figures indicate the date and time of the photographs.

[0058] As shown in Figures 10 to 13, the area of ​​the allergic dermatitis on the caudal abdomen narrowed with each treatment, confirming that the symptoms were alleviated. In addition, the gradual appearance of hair around the affected area was confirmed after treatment.

[0059] As described above, it was confirmed that treatment with the dermatitis-ameliorating ozone bubbling device 100 alleviates the symptoms of allergic dermatitis regardless of the location of the affected area. [Test Example 2] (Verification of effect on seborrheic dermatitis) We tested its effectiveness against seborrheic dermatitis in Shih Tzu dogs.

[0060] The affected area of ​​seborrheic dermatitis was periodically immersed for 10 minutes in the dermatitis-improving ozone bubbling device 100, and the progress of the affected area was observed. The concentration of the ozone-containing gas in the water was less than 0.1 ppm. The temperature of the water was 35 to 37°C.

[0061] This treatment was performed once a week, and stopped after 30 sessions. After that, the patient was observed for several months with only cleaning, and then the treatment was performed again once a week.

[0062] Fig. 14 shows the condition of the affected area (left forearm) after the first treatment with the dermatitis improving ozone bubbling device 100. Fig. 15 shows the condition of the affected area (left forearm) after the 21st treatment with the dermatitis improving ozone bubbling device 100. Fig. 16 shows the condition of the affected area (left forearm) after the 56th treatment with the dermatitis improving ozone bubbling device 100. The numbers in the figures indicate the date and time when the images were taken.

[0063] As shown in Figures 14 to 16, the area of ​​the seborrheic dermatitis on the left forearm narrowed with each treatment, confirming that the symptoms were alleviated. In addition, the gradual appearance of hair around the affected area was confirmed after treatment.

[0064] In addition, according to the observer's records, the itching in the affected area, mainly in the abdomen, decreased immediately after the treatment. After the 10th treatment, there was a marked improvement in the seborrhea and scales in the affected area.

[0065] In contrast, when the treatment was stopped, seborrhea worsened and itching increased. After the treatment was resumed and after 10 treatments, the seborrhea in the affected area improved and the scales disappeared. After the treatment was resumed and after 30 treatments, the rash was almost cured.

[0066] As described above, the dermatitis-ameliorating ozone bubbling device 100 and the dermatitis-ameliorating method were confirmed to be effective in alleviating the symptoms of dermatitis including allergic dermatitis and seborrheic dermatitis. [Test Example 3] (Verification of the effect on skin condition) A dog suffering from a skin disease was treated with an ozone bubbling device, and the skin condition was observed before and after the treatment. The treatment conditions were the same as those of Test Example 2, so the explanation is omitted.

[0067] The study subjects were 14 dogs aged 6 to 15 years. There were 5 males (2 of which were intact) and 9 females (2 of which were intact). The dog breeds studied were Shih Tzu, Toy Poodle, Pug, Shiba Inu, Chihuahua, French Bulldog, and Miniature Dachshund.

[0068] Of the 14 dogs in the study, 10 had seborrheic dermatitis, 6 had pyoderma, and 2 of 14 had both seborrheic dermatitis and pyoderma.

[0069] The test was evaluated by the attending physician before the treatment, immediately after the treatment, and 7 days after the treatment, regarding the following items: fur gloss, hair loss, desquamation, body odor, and skin balance. The items of fur gloss, hair loss, desquamation, body odor, and skin balance were evaluated using the following indices. These evaluation items are correlated with the condition of dermatitis (degree of symptoms), and there is a tendency for these evaluation items to improve together with the improvement of dermatitis. [Coat gloss] The coat gloss was evaluated according to the following criteria: The higher the score, the better the coat gloss.

[0070] Evaluation criteria 1: Very dull 2: Dull 3: Slightly dull 4: Normal 5: Slightly shiny 6: Shiny 7: Very shiny [Hair removal] The degree of hair loss was evaluated according to the following criteria: The higher the score, the lighter the degree of hair loss.

[0071] Evaluation criteria 1: Very severe 2: Severe 3: Slightly severe 4: Moderate 5: Mild 6: Few 7: None [Desquamation] The degree of desquamation, commonly known as "dandruff," was evaluated according to the following criteria: The higher the score, the milder the degree of desquamation.

[0072] Evaluation criteria 1: Very severe 2: Severe 3: Slightly severe 4: Moderate 5: Mild 6: Few 7: None [body odor] The degree of body odor was evaluated according to the following criteria: The higher the score, the better the degree of body odor.

[0073] Evaluation criteria 1: Very unacceptable 2: Unacceptable 3: Acceptable 4: None 5: Slightly pleasant smell 6: Pleasant Smell 7: Very pleasant smell [Skin balance (balance between oily and dry skin)] The skin condition was evaluated in terms of the balance between oiliness and dryness. The higher the score, the better the balance of the skin condition.

[0074] Evaluation criteria 1: Very oily or very dry 2: Oily or dry 3: Slightly oily or slightly dry 4: Normal The average scores for each evaluation item are shown in Table 1.

[0075] [Table 1] As shown in Table 1, in all items including coat gloss, hair loss, desquamation, body odor, and skin balance, the scores were higher immediately after treatment than before treatment. Also, even 7 days after treatment, the scores were higher than before treatment.

[0076] For the average value of each evaluation in Table 1, the maximum value ratio (%) was calculated using the following formula. The maximum value ratio (%) is the ratio of the average value to the highest evaluation point expressed as a percentage. In other words, it is an index showing the range of evaluation for each item, and the higher the maximum value ratio, the less the variation in evaluation can be evaluated. Each maximum value ratio (%) is shown in Table 2. Maximum value ratio (%) = (average value / maximum value) x 100

[0077] [Table 2] As shown in Table 2, the maximum value ratio (%) for skin balance immediately after treatment and 7 days after treatment is very high, and the data shows little variation in values. In other words, the skin balance in particular can be evaluated as having an improvement effect on skin condition regardless of individual differences.

[0078] For each evaluation in Table 1, the improvement rate (%), which indicates the degree of improvement in skin condition, was calculated using the following formula. The improvement rate (%) is expressed as a percentage of the degree of improvement immediately after treatment and the degree of improvement 7 days after treatment, based on the condition before treatment.

[0079] Immediately after treatment: 100 x (average value immediately after treatment - average value before treatment) / average value before treatment 7 days after treatment: 100 x (average value after 7 days after treatment - average value before treatment) / average value before treatment

[0080] [Table 3] As shown in Table 3, all of the items of fur gloss, hair loss, desquamation, body odor, and skin balance showed a tendency to improve immediately after the treatment. In addition, the evaluation of fur gloss, desquamation, body odor, and skin balance showed a tendency to improve, although the improvement rate was lower 7 days after the treatment than immediately after the treatment. In particular, the items of body odor and skin balance maintained a high improvement rate (%) even after a long time had passed since the treatment, and it can be said that the sustained effect is high. In addition, the improvement rate (%) of hair loss 7 days after the treatment was higher than immediately after the treatment. Therefore, it was found that the effect of hair loss is likely to be seen after a certain period of time had passed since the treatment. There was no adverse event, and no case in which the test was discontinued. From the above, it can be said that the use of the ozone bubbling device of this embodiment in surgery can be expected to have an effect of improving the skin condition. [Explanation of symbols]
