Abstract

The present invention relates to a decubitus ulcer prevention device, which comprises an air generator having a fan, an air mattress for receiving air, from the air generator, that is discharged at a surface through minute air discharge holes, and a hose for connecting the air mattress to the air generator. Along a flow path of the air that passes through the fan, are located, in order as named, a heater and an alkaline chlorine dioxide gas generator, in which is internally provided a ceramic body that is impregnated with an alkaline chlorine dioxide solution. Air that is heated, by passing through the heater, is brought into contact with the ceramic body, so that air that includes alkaline chlorine dioxide gas is thus supplied to the air mattress.

Claims

1. A decubitus ulcer prevention device comprising:

an air generator having a fan,

an air mattress for receiving air, from said air generator, that is discharged at a surface through minute air discharge holes, and

a hose for connecting said air mattress to said air generator,

wherein, along a flow path of said air that passes through said fan, are located, in order as named, a heater and an alkaline chlorine dioxide gas generator, in which is internally provided a ceramic body that is impregnated with an alkaline chlorine dioxide solution, whereby air that is heated, by passing through said heater, is brought into contact with said ceramic body, so that air that includes alkaline chlorine dioxide gas is thus supplied to said air mattress.

3. A decubitus ulcer prevention device according to claim 1, wherein said alkaline chlorine dioxide gas generator is stored detachably in said air generator.

4. A decubitus ulcer prevention device according to claim 1, wherein said alkaline chlorine dioxide gas generator is installed outside said air generator and is so connected to said hose as to be detachable.

5. A decubitus ulcer prevention device according to claim 1, wherein a unit for supplying an alkaline chlorine dioxide solution to said ceramic body is detachably attached to said alkaline chlorine dioxide gas generator, and formed in said ceramic body is a solution supply groove for supplying said alkaline chlorine dioxide solution to a surrounding side portion of said ceramic body.

7. A decubitus ulcer prevention device according to claim 1, wherein said alkaline chlorine dioxide solution that is used to permeate said ceramic body, which is impregnated with said alkaline chlorine dioxide solution, has a calculated chlorine dioxide content of 50 ppm to 1000 ppm.

9. A decubitus ulcer prevention device according to claim 1, wherein said ceramic bodies are columnar in shape, and in cross section have a plurality of longitudinal through holes.

10. A decubitus ulcer prevention device according to claim 1, wherein said ceramic bodies are formed from alkaline ceramics that contain at least one material selected from a group consisting of animal bone powder, shell powder, limestone powder, and coral powder.

11. A decubitus ulcer prevention device according to claim 10, wherein said alkaline ceramic contains animal bone powder as the main activated element.

12. A decubitus ulcer prevention device according to claim 10, wherein said alkaline ceramic contains at least one ceramic selected from a group consisting of silica gel, alumina, and zeolite.

2. A decubitus ulcer prevention device, which comprises:

an air generator having a fan,

an air mattress for receiving air, from said air generator, that is discharged at a surface through minute discharge holes, and

a hose for connecting said air mattress with said air generator,

wherein, along a flow path of said air that passes through said fan, is located an alkaline chlorine dioxide gas generator, in which a ceramic body that is impregnated with a citric acid solution is provided on a side adjacent to said fan and a ceramic body that is impregnated with an alkaline chlorine dioxide solution is provided following said ceramic body that is impregnated with a citric acid solution, whereby air that passes through said fan contacts said ceramic bodies, so that air that includes alkaline chlorine dioxide gas is thus supplied to said air mattress.

6. A decubitus ulcer prevention device according to claim 2, wherein a unit for supplying a citric acid solution to said ceramic body is detachably attached to said alkaline chlorine dioxide gas generator, and formed in said ceramic body is a solution supply groove for supplying said citric acid solution to a surrounding side portion of said ceramic body.

8. A decubitus ulcer prevention device according to claim 2, wherein said citric acid solution that is used to permeate said ceramic body is adjusted to pH 2 to pH 5.

13. A decubitus ulcer prevention device according to claim 2, wherein said alkaline chlorine dioxide gas generator is stored detachably in said air generator.

14. A decubitus ulcer prevention device according to claim 2, wherein said alkaline chlorine dioxide gas generator is installed outside said air generator and is so connected to said hose as to be detachable.

15. A decubitus ulcer prevention device according to claim 2, wherein a unit for supplying an alkaline chlorine dioxide solution to said ceramic body is detachably attached to said alkaline chlorine dioxide gas generator, and formed in said ceramic body is a solution supply groove for supplying said alkaline chlorine dioxide solution to a surrounding side portion of said ceramic body.

16. A decubitus ulcer prevention device according to claim 2, wherein said alkaline chlorine dioxide solution that is used to permeate said ceramic body, which is impregnated with said alkaline chlorine dioxide solution, has a calculated chlorine dioxide content of 50 ppm to 1000 ppm.

17. A decubitus ulcer prevention device according to claim 2, wherein said ceramic bodies are columnar in shape, and in cross section have a plurality of longitudinal through holes.

18. A decubitus ulcer prevention device according to claim 2, wherein said ceramic bodies are formed from alkaline ceramics that contain at least one material selected from a group consisting of animal bone powder, shell powder, limestone powder, and coral powder.

19. A decubitus ulcer prevention device according to claim 18, wherein said alkaline ceramic contains animal bone powder as the main activated element.

20. A decubitus ulcer prevention device according to claim 18, wherein said alkaline ceramic contains at least one ceramic selected from a group consisting of silica gel, alumina, and zeolite.
