Medical apparatus using ozone gas

Claim 2

A medical apparatus using ozone gas, comprising: an airtight body for hermetically accommodating affected bodily parts, said airtight body having an opening through which the affected bodily parts can be inserted therein; an ozonizer; gas feeding means connected to the ozonizer, said feeding means being in communication with said airtight body so as to feed ozone gas thereto; gas withdrawing means for withdrawing ozone gas from said airtight body while maintaining inner pressure thereof; and said airtight body comprising an outer bag and an inner bag, the affected parts being insertable into the inner bag, the bags being made of plastic film, a space being formed between the bags as a path for ozone gas, the inner bag having a plurality of through-holes communicating with the path.

Claim 3

The medical apparatus according to claim 1, further comprising a band for hermetically sealing affected bodily parts in said airtight body, said band being provided at the opening of said airtight body.

Claim 4

The medical apparatus according to claim 1, wherein said gas feeding means comprises means defining a feeding path for ozone gas and said gas withdrawing means comprises means defining a withdrawing path for ozone gas, said airtight body is divided into a first-half section and a second-half section, one of the sections communicating with the feeding path and the other section communicating with the withdrawing path.

Claim 5

The medical apparatus according to claim 1, further comprising pressure adjusting means for maintaining inner pressure of said airtight body, said pressure adjusting means communicating with the withdrawing path.

Claim 6

A medical apparatus using ozone gas, comprising: an ozonizer including means for forming ozone gas, means for feeding ozone gas and means for withdrawing ozone gas; a conduit member having a feeding path and a withdrawing path, one end of said conduit member communicating with the gas feeding means and the gas withdrawing means, the feeding path communicating with the gas feeding means and the withdrawing path communicating with the gas withdrawing means; a hood having one end connected to the other end of said conduit member and an opposite end which is open; and a sprayer of a generally hollow truncated cone shape, said sprayer being provided entirely within said hood, an annular space being formed between said sprayer and said hood, said sprayer communicating with one of the feeding path and the withdrawing path, said annular space communicating with the other of the feeding path and the withdrawing path, said sprayer having an end wall through which is formed a plurality of through-holes through which ozone gas passes, said through-holes and said open end of said hood substantially lying in respective planes, said planes being substantially parallel to each other and spaced only a slight distance from each other.

Claim 7

A medical apparatus using ozone gas, comprising: an ozonizer including means for forming ozone gas, means for feeding ozone gas and means for withdrawing ozone gas; a conduit member having a feeding path and a withdrawing path, one end of said conduit member communicating with the gas feeding means and the gas withdrawing means, the feeding path communicating with the gas feeding means and the withdrawing path communicating with the gas withdrawing means; a hood having one end connected to the other end of said conduit member and an opposite end which is open; and a sprayer of a generally hollow truncated cone shape, said sprayer being provided entirely within said hood, an annular space being formed between said sprayer and said hood, said sprayer communicating with one of the feeding path and the withdrawing path, said annular space communicating with the other of the feeding path and the withdrawing path, said sprayer having an end wall through which is formed a plurality of through-holes through which ozone gas passes, said through-holes and said open end of said hood substantially lying in respective planes, said planes being substantially parallel to each other and spaced only a slight distance from each other.

Claim 8

The medical apparatus according to claim 5, wherein said end wall of said sprayer has a concave center section.

Claim 9

The medical apparatus according to claim 3, further comprising a skirt made of a soft sheet material, said skirt being fixed around said hood and extending in a direction toward the open end of said hood and ending beyond the open end of said hood.

Claim 10

The medical apparatus according to claim 6, in which the sprayer communicates with the feeding path and the annular space communicates with the withdrawing path.
