A system is provided for testing whether an iontophoretic drug delivery device is in an appropriate state for administering a therapeutic agent into an animal body. An electrical characteristic of at least one electrical path associated with an electrode test point is used to determine whether the iontophoretic device is in an appropriate state. The measured electrical characteristic indicates that the iontophoretic device is in an appropriate state for administering the therapeutic agent into the animal body when the therapeutic agent is properly disposed with respect to the electrodes of the iontophoretic device.

The present invention relates to a device for applying a cosmetic composition (P), comprising: —a capsule (1) that delimits a housing (10), —an application member (6) positioned in the housing (10) and impregnated with a cosmetic composition (P), —an electric exciter (29) comprising at least two electrodes (4, 5) in contact with the application member (6) and making it possible to circulate an electric current between these two electrodes (4, 5).

A switch-operated therapeutic agent delivery device. Embodiments of the operated therapeutic agent delivery device my include a switch that can be operated by a user, a device controller connected to the switch through a switch input where the device can actuate the device when certain predetermined conditions are met, following performance of both a digital switch validation test and an analog switch validation test. The switch operated therapeutic agent delivery device may have two parts, which are assembled by a user prior to use. These devices may be configured to determine if a current is present between the anode and cathode when drug is not intended to be delivered by the device. These devices may indirectly control and/or monitor the applied current without directly measuring from the cathode of the patient terminal.

Disclosed is a sheet mask for iontophoresis including: a first boring portion which is formed at least one portion of portions corresponding to eyes, a nose, and a mouth of a user face; and a second boring portion which is formed to connect an electrode portion, wherein the number of second boring portions is one to six.

Various embodiments provide methods and systems for the biphasic iontophoretic transdermal delivery of therapeutic agents. An embodiment of a method for such delivery comprises positioning at least one electrode assembly in electrical communication with a patient's skin. The assembly includes a solution comprising a therapeutic agent which passively diffuses into the skin. A dose of agent is delivered from the assembly into the skin during a first period using a first current having a characteristic e.g., polarity and magnitude, to repel the agent out of the assembly. During a second period, a second current having a characteristic to attract the agent is used to retain the agent in the assembly such that delivery of agent into skin is minimized. A dose of agent may be delivered on demand by an input from the patient. Embodiments may be used for delivery of agents which cause adverse effects from unwanted passive diffusion.

The invention relates to an end piece intended for equipping a device for cosmetic treatment of keratin materials with an electric current, the end piece comprising an application member (6) comprising an electrode (1) and a counter electrode (2), said electrode (1) and counter electrode (2) being separated from one another by an electrically insulating zone (3).

An iontophoretic device including a multichannel driver connected to multiple electrodes, a medication reservoir positioned distal to the multiple electrodes and including multiple reservoir chambers, and a resistive barrier material at least partially surrounding one or more of the multiple electrodes and one or more of the multiple reservoir chambers, the resistive barrier material configured to provide a least resistive current flow path running from an active electrode to a tissue contact point most proximal to the active electrode.

An embodiment relates to a transdermal drug delivery system comprising a patch comprising a) a cartridge comprising a drug; b) a bio-sensor and a non bio-sensor; c) an active delivery pad comprising an electrode for delivery of the drug into a tissue via iontophoresis; d) a power source of electrical energy connected to the electrode; e) a microcontroller configured to control a release of the drug wherein the patch is attached to the tissue via an adhesive pad, and optionally top of patch is covered with a sheet; wherein the bio-sensor is configured to detect a physiological parameter; wherein the non bio-sensor is configured with a software to control working of the patch.

Disclosed is an iontophoresis administration device. The iontophoresis administration device includes a power supply for generating the electricity needed to penetrate a medicament to be penetrated into an administered area of an organism; an integrated dielectric layer for covering the administered area, and including a gel and the polar, free-state medicament to be penetrated; and a plurality of electrodes for respectively electrically connecting with the power supply and the integrated dielectric layer so that the electricity generated by the power supply flows through the administered areas and at least part of the integrated dielectric layers respectively, and the at least part of the integrated dielectric layers has a predetermined resistance value. The iontophoresis administration device not only can improve the transdermal efficiency, but also are not prone to skin damage.

A system and method is provided for healing a wound in a subject in need thereof. The system includes a wound dressing that has a therapeutic agent and at least one electrode in electrical communication with the therapeutic agent. The system also includes a power source in electrical communication with the at least one electrode and a vacuum source in fluid communication with the wound dressing.
