Estimating the term…
The present invention relates to an iontophoresis device, which can ensure the long-term stability of a drug and makes the operations for assemblage upon application easy as well as a method of assembling the device. A backing layer (4) is provided with a drug-dissolving portion (11) on a donor electrode-printed portion (6) thereof and a drug support (14) removably contacts with the drug-dissolving portion. A liner (12) is disposed on the backing layer on the skin (40) side and this is peeled off upon practical use. An opening (15) is formed on the liner (12) and an opening (5) is formed on an electrode portion (Ib). When assembling the device, these openings coincide with each other to thus easily and precisely dispose the drug support (14) on the drug-dissolving portion (11).
An iontophoresis device comprising a drug-dissolving portion provided with an electrode portion having a first alignment structure and a drug support provided with a drug portion having a second alignment structure, which coincides with the first alignment structure, wherein the drug support contacts with the drug-dissolving portion by coinciding the second alignment structure of the drug portion with the first alignment structure of the electrode portion.
An iontophoresis device comprising a drug-dissolving portion provided with an electrode portion having a first alignment structure, a current-generating portion having a third alignment structure, which coincides with the first alignment structure and a connector having a fifth alignment structure, which coincides with the first alignment structure, wherein the electrode portion, the current-generating portion and the connector are coupled together while the electrode portion is sandwiched between the current-generating portion and the connector by coinciding the said alignment structures with each other.
An iontophoresis device comprising a current-generating portion for supplying a driving force for drug-absorption, a drug portion provided with a drug support and an electrode portion provided with a drug-dissolving portion, wherein the electrode portion and the drug portion are arranged while they are in contact and in line with one another by the use of a means for maintaining the arrangement upon operation of the device to thus contact the drug support of the drug portion with the drug-dissolving portion of the electrode portion.
An iontophoresis device set at least comprising an electrode portion having a first alignment structure and a drug-dissolving portion;
A method of assembling an iontophoresis device, which comprises an electrode portion having an alignment structure and a drug-dissolving portion covered with a cover material;
A method of assembling an iontophoresis device comprising the step of coinciding an alignment structure of an electrode portion with an alignment structure of a drug portion using at least one of alignment structures of an auxiliary stand for assemblage, a current-generating portion and a connector to thus put a drug support of the drug portion in position on a drug-dissolving portion of the electrode portion.
