Description
The present invention relates to the system that electric drive (electrotransport) transmits medicine, it comprises parts and a controller that re-uses that has the control circuit that is powered of a powder charge.The parts of this powder charge and controller are detachably coupled together them by a bonder, so just set up being electrically connected between these parts and the controller.
" electric drive " used herein this term typically refer to transmit a kind of reagent (such as: medicine), make it pass a kind of film, such as skin, mucosa or fingernail.This transmission is in the help of electromotive force or induces down and finish.For example, a kind of useful treatment reagent blood circulation that can under the inducing that electric drive transmits, enter human body by skin.Electromigration (being also referred to as ionophoresis (iontophoresis)) is an electric drive process of widely using, it and charged ion mobile relevant under the inducing of electricity.The electric drive electro-osmosis of another kind of type with liquid mobile relevant under effect of electric field, comprises the reagent of needs transmission in the liquid.Electric drive-electric the holeization (eletroporation) of another kind of type is with under effect of electric field, and the formation in the temporary transient hole that exists is relevant in the biomembrane.The agent examination can enter in the hole in mode (promptly under the effect of electromotive force) initiatively, or enters in the hole in passive mode (promptly not having the help of electricity).Yet, in the process of above any electric drive, have at least two kinds of processes to take place simultaneously to a certain extent.Corresponding, " electric drive " used herein this term should be invested the most possible explanation, be that it comprises at least a reagent (this reagent may be charged, may be not charged yet, or the both has) the transmission that under the inducing of electricity or by electricity, improves, and no matter this reagent is the transmission of carrying out with any or several mechanism actually.
Electronic driver uses at least two electrodes, and the other parts of they and skin, fingernail, mucosa or body surface electrically contact.One of them electrode is commonly referred to " alms giver " or " initiatively " electrode, is that medicament is sent into intravital electrode.Another electrode is commonly referred to negation or " returning " electrode, is used for making circuit to pass through to form the loop behind the health.For example, if the reagent that transmits is positively charged, i.e. cation, then anode is initiatively or donor electrode, at this moment negative electrode is used for making circuit to become the loop.If reagent is electronegative conversely speaking,, i.e. anion, then negative electrode is a donor electrode.In addition, if contain cation and anion simultaneously in the medicament that transmits, or uncharged or neutral reagent, then anode and negative electrode all are donor electrode.
In addition, the electric drive transfer system needs a container or a reagent source of waiting to transmit reagent usually at least, and reagent is liquid solution or suspension normally.This reagent container comprises sack or cavity, porous sponge or mat and hydrophilic polymers or gel-in-matrix.This alms giver's container is connected with body surface with negative electrode (or negative pole), and is positioned between the two, is used to provide the fixed or renewable reagent source or the medicine source of one or more medicaments or reagent.Electronic driver has a power supply, as being made up of one or more batteries.Usually, a utmost point of power supply links to each other with donor electrode, and the other end links to each other with antielectrode.In addition, some electronic driver has an electric controller, controls the electric current of the electrode of flowing through by it, thereby the transfer rate of reagent is regulated.In addition, passive mobile controlling diaphragm, the binding agent that assurance device contacts with body surface, insulation assembly, and fluid-tight liner other available parts that are electronic driver.
The reagent delivery of all electric drive all uses circuit that power supply (as battery) and electrode are linked up.In some simply install, as disclosed in the United States Patent (USP) 4,474,570 of inventions such as Ariura, should " circuit " be one section conductor wire just, with it battery and electrode are connect.The device that has has used multiple electronic component that the electric current that power supply provides is controlled, and adjusts its amplitude, polarity, conduction time, and waveform etc.Can be referring to the United States Patent (USP) 5,047,007 of inventions such as McNichols.
