Mihama Seisakusho to*S Actual Inventor(s): Address for Service: Mamoru Hama, Matao Mitsuyoshi and Takahiru Hashimoto Spruson Ferguson, Patent Attorneys Level 33 St Martins Tower, 31 Market Street Sydney, New South Wales, 2000, Australia Medical Treatment Apparatus Using Ozone Gas Invention Title: The following statement is a full description of this invention, including the best method of performing it known to me/us:- 5845/3 A MEDICAL APPARATUS USING OZONE GAS FIELD OF TECHNOLOGY The present invention relates to a medical apparatus using ozone gas. and more particularly relates to a medical apparatus for spraying ozone gas to affected bodily parts to anesthetize them.

BACKGROUND TECHNOLOGY Ozone is a quite strong oxidizing agent and its use for sterilization, decoloralion, deodorization, etc. is known. Conventionally, ozone gas has been used for vaious procedures.

For example, its sterilization ability is used for purifying rooms, sterilizing foods for storage, sterilizing water in water supply systems and pools, and disinfecting wounds and fascia; its decoloration and deodorization abilities are used for deodorizing water supply systems and sewage disposal systems, and purifying air in hotels and hospitals; furthermore, ozone is used for oxidation, ozonolysis, surface activation, etc.

As described above, ozone gas is generally used for sterilization, decoloration and Sdeodorization in the industrial field. Furthermore, considering its sterilization ability, there have been some propositions to use ozone for sterilizing wounds; curing athlete's foot; a facial culture device for stimulating skin and accelerating blood circulation.

The inventors studied usages of ozone gas and found that ozone gas has not only S: 20 the above described functions but also a pronounced anesthetic effect. For example, it has been found that a pain caused by inflammation of a sprain can be effectively reduced by spraying ozone gas to the affected part. This anesthetic effect can be gained by only spraying ozone gas to affected bodily parts, and it is found that ozone gas is capable of reducing pains in various bodily parts, such as lumbar region, joints, etc.

The anesthetic function is different from the above described sterilization, decoloration and deodorization, and the anaesthetic function will be effective in the medical field. The present invention pays attention to the pain-killing function, and an object of the invention is to provide a medical apparatus using ozone gas, which is capable of easily anesthetizing affected bodily parts, such as arms, legs, etc.

25 BRIEF DESCRIPTION OF THE DRAWINGS An embodiment of the invention will now be described with reference to the accompanying drawings, in which: Fig. 1 shows an explanatory view showing a" main part of a first form of the present invention and its state of usage; and Fig. 2 shows an explanatory view showing a whole structure of the first form of the invention.

BEST MODE OF CARRYING OUT THE INVENTION A preferred embodiment of the present invention will now be described in detail with reference to Figs 1. and 2.

Item 20 is a tubing member for forwarding and withdrawing ozone gas, and has a 20220 forwarding path 22 for forwarding ozone gas and a withdrawing path 24 for withdrawing and discharging ozone gas. The one end section of the tubing member 20 is connected to an ozonizer 26, as shown in Fig. 2, and the forwarding path 22 is communicated with the gas forwarding mechanism of the ozonizer 26; the withdrawing path 24 is communicated with the gas withdrawing mechanism thereof.

The tubing member 20 is extended upward from the ozonizer 26, and is bent in an L-shape as shown in Fig. 2. At the bent section, the tubing member 20 is supoorted by a stand 28.

There is fixed a cylindrical hood 30, whose diameter is gradually enlarged toward the lower end, at the front end of the tubing member 20. The lower end of the hood faces downward.

The front ends of the forwarding path 22 and the withdrawing path 24 open into the hood 30, as shown in Fig. 1.

There is fixed a sprayer 32, which is formed like a hollow truncated cone, in the hood 30. The sprayer 32 is communicated with the forwarding path 22. The sprayer 32 is extended toward the lower end of the hooo 30, and the inner diameter thereof is gradually enlarged toward the lower end thereof. There is formed a narrow space between the outer circumferential face of the spriyer 32 and the inner face of the hood There is formed a spraying section 32a in the sprayer 32. The spraying section 32a corresponds to the open-lower end of the hood 30. The center of the spraying section 32a is slightly concave, and there are provided perforations 34 therein so as to pass ozone gas.

Note that, the spraying section 32a is located slightly above the lower end of the hood 30, so that the lower end of spraying section 32a and the lower end of the hood 0o are not coplanar.

When the above described apparatus is in use, affected bodily parts, such as arms, legs, etc., are positioned proximate to the open end of the hood 30, and ozone gas sprayed from the spraying section 32a contacts the affected bodily parts.

Ozone gas formed by the ozonizer 26 is introduced in the sprayer 32 via the forwarding path 22, and sprayed from the perforations 34. Sprayed ozone gas contacts affected bodily parts, and returns to the ozonizer 26 via the withdrawing path 24.

Ozone gas sprayed from the sprayer 32 is contained within the hood 30 so as not to leak into the atmosphere, as shown in Fig. 1, and is withdrawn via the withdrawing path 24, so that the gas can be recirculated effectively.

Note that, as shown in Fig. 1, there is provided a skirt 36 around the outer circumferential surface of the lower end of the hood 30. The skirt 36 covers affected parts proximate to the hood 30, so that ozone leakage can be suppressed.

In the apparatus of this embodiment, an affected bodily part can be exposed to ozone gas by positioning said part proximate to the lower end of hood 30, so it is very easy touse the apparaltus.

Ozone gas can be easily sprayed to not only arms and legs but also about the torso.

Furthermore, the hood 30 way be provided in a variety of shapes, the tubing member may be flexible, and the tubing member may have a telescopic structure, so that the apparatus can be used more easily and patients can be treated in comfortable positions.

By covering the affected bodily parts by the hood 30 or the skirt 36 to suppress the leakage, the quantity of ozone used can be reduced, and relatively high density ozone gas can be used for treatment.

Note that, ozone gas is withdrawn in the apparatus but the gas withdrawn can be released to the atmosphere after a harmless treatment, such as heating. On the other hand, S the gas withdrawn may be reused. Furthermore, if the ozone concentration is quite low, i'"'"the gas can be released to the atmosphere without treatment.

In this embodiment, the sprayer 32 is attached to the forwarding path 22. But the paths 22 and 24 may be arranged vice versa and the sprayer 32 may be communicated with the path 24. With this structure, ozone gas will be sprayed from the hood 30 and be withdrawn via the sprayer 32. In such cases, this counter structure can further suppress ozone leakage.

S 20 A preferred embodiment of the present invention has been described in detail but the pLr esent invention is not limited to the above embodiment. Many modifications can be made without deviating from the scope of the invention or the claims.
