Device for storing and administering active ingredients, and method for administering active ingredients by means of such device

A method for administering an active substance, comprising:

• providing an apparatus having:
• a first reservoir containing a carrier medium and the active substance dissolved in the carrier medium;
• at least one transfer mechanism for the active substance, wherein the transfer mechanism for the active substance is a micro-needle;
• a second reservoir containing the active substance in solid form;
• and
• a package surrounds the first and the second reservoir;
• applying the apparatus onto a target surface;
• exerting a pressure on the apparatus to cause the micro-needle to pierce the package and penetrate into the target surface;
• transporting the active substance out of the first reservoir into the target surface via the micro-needle;
• and
• replacing an amount of active substance that is transported out of the first reservoir into the target surface by transporting the solid active substance from the second reservoir to the first reservoir, whereupon the transported solid active substance becomes dissolved in the carrier medium.

An apparatus for storing and administering at least one active substance, comprising:

• a first reservoir containing a carrier medium and the at least one active substance dissolved in the carrier medium;
• at least one transfer mechanism for the active substance, wherein the transfer mechanism is a micro-needle;
• and
• a second reservoir containing the active substance in solid form;
• wherein a carrier structure permeable to the active substance extends across the first reservoir, and wherein the transfer mechanism is mounted on the carrier structure, and wherein the first reservoir is divided into a first region having the transfer mechanism and a second region without the transfer mechanism;
• wherein a package surrounds the first and second reservoirs, and wherein the package is formed from an elastic film forming an upper half of the package and an outer layer forming a lower half of the package, the elastic film configured to be pierced by the micro-needle, and wherein the elastic film and the outer layer are connected to one another at their edge regions.

An apparatus for storing and administering at least one active substance, comprising:

• a first reservoir containing a carrier medium and the at least one active substance dissolved in the carrier medium;
• at least one transfer mechanism for the dissolved active substance, the at least one transfer mechanism transferring the dissolved active substance to a surface external to the apparatus when activated;
• a second reservoir containing the active substance in solid form;
• and
• a transport structure configured to transport the solid active substance from the second reservoir to the first reservoir, wherein the transported solid active substance becomes dissolved in the carrier medium in the first reservoir;
• wherein:
• the first reservoir and the second reservoir adjoin one another;
• the transport structure is a separating layer disposed between the first reservoir and the second reservoir;
• a package surrounds the first and the second reservoir;
• the transfer mechanism for the active substance is a micro-needle;
• the package is formed from an elastic film forming an upper half of the package and an outer layer forming a lower half of the package;
• the elastic film is configured to be pierced by the micro-needle when the package is compressed;
• and
• the elastic film and the outer layer are connected to one another at their edge regions.
