MIKROVENTIL ZUM FÜLLEN DES BEHÄLTERS EINES TRANSDERMALEN MEDIKAMENTENVERABREICHUNGSSYSTEMS

摘要

A miniature valve for filling the reservoir of an apparatus for the transdermal administration of a medicine including a) a substrate, b) a fuel charge arranged on the substrate opposite the passage to be opened through it, and c) an electric resistor placed in contact with the fuel charge so that the supply of this resistor with a predetermined electric energy ensures the combustion of the charge and the opening of the passage by local rupture of the substrate under the pressure of the fuel gases of the charge. The device is useful for filling a medicine reservoir for the transdermal administration medicine aided by inophoresis.
