Abstract

Provided is a packaged iontophoresis system 15 including: an iontophoresis system 10 including an apparatus body 50 for transdermally delivering an ionized drug by iontophoresis, and a connection part 70 extended from the apparatus body 50 and connected to the apparatus body 50 and a power source 60, the power source 60 supplying power to the apparatus body 50; a package material 80 hermetically packaging the apparatus body 50 and a portion of the connection part 70, by at least a part thereof being welded to the connection part 70; and a cutting guide 400 guiding a cutting line of the package material 80 so that the part of the package material 80 welded to the connection part 70 remains at the connection part 70 when the package material 80 is opened.

Claims

1. A packaged iontophoresis system comprising:

an iontophoresis system including an apparatus body for transdermally delivering an ionized drug by iontophoresis, and a connection part extended from the apparatus body and connected to the apparatus body and a power source for supplying power to the apparatus body;

a package material hermetically packaging the apparatus body and a portion of the connection part, by at least a portion thereof being fixed to the connection part; and

a cutting guide guiding a cutting line of the package material so that the portion of the package material fixed to the connection part remains at the connection part when the package material is opened and removed.

2. The packaged iontophoresis system according to claim 1, wherein

the cutting guide includes a groove in a thickness direction and provided between the part thereof that is fixed to the connection part and the other part thereof.

3. The packaged iontophoresis system according to claim 2, wherein

the cutting guide includes a notch provided in a vicinity of the part thereof that is fixed to the connection part.

4. The packaged iontophoresis system according to claim 2, wherein

the part of the package material fixed to the connection part is fixed more strongly than any other part of the package material.

5. The packaged iontophoresis system according to claim 3, wherein

the part of the package material fixed to the connection part is fixed more strongly than any other part of the package material.

6. The packaged iontophoresis system according to claim 1, wherein

the cutting guide includes a notch provided in a vicinity of the part thereof that is fixed to the connection part.

7. The packaged iontophoresis system according to claim 6, wherein

the part of the package material fixed to the connection part is fixed more strongly than any other part of the package material.

8. The packaged iontophoresis system according to claim 1, wherein

the part of the package material fixed to the connection part is fixed more strongly than any other part of the package material.

9. The packaged iontophoresis system according to claim 1, wherein

the apparatus body includes:

an operation electrode structure including a first electrode member and a drug solution retainer, the first electrode member being electrically connected to a first conductivity type terminal of a power source, the first conductivity type being the same as a conductivity type of the ionized drug, the drug solution retainer retaining a drug solution containing the drug and being provided in an electric field created by the first electrode member; and

a non-operation electrode structure electrically connected to a second conductivity type terminal of the power source, the second conductivity type being opposite to the first conductivity type.

10. The packaged iontophoresis system according to claim 9, wherein

the operation electrode structure further includes:

a first electrolyte retainer electrically connected to the first electrode member and retaining an electrolyte;

an ion exchange membrane of the second conductivity type sandwiching the first electrolyte retainer with the first electrode member, and selectively permeating ions of the second conductivity type; and

an ion exchange membrane of the first conductivity type sandwiching the drug solution retainer with the ion exchange membrane of the second conductivity type, and selectively permeating ions of the first conductivity type.

11. The packaged iontophoresis system according to claim 10, wherein

the counter electrode structure includes:

a second electrode member electrically connected to the terminal of the second conductivity type of the power source;

a second electrolyte retainer electrically connected to the second electrode member and retaining an electrolyte;

an ion exchange membrane of the first conductivity type sandwiching the second electrolyte retainer with the second electrode member, and selectively permeating an ion having an electric polarity different from an electric polarity of the second electrode member;

a third electrolyte retainer provided in an opposite side of the second electrolyte retainer in the ion exchange membrane of the first conductivity type, and retaining an electrolyte; and

an ion exchange membrane of the second conductivity type sandwiching the third electrolyte retainer with the ion exchange membrane of the first conductivity type, and selectively permeating an ion having an electric polarity that is the same as the electric polarity of the second electrode member.
