Abstract
An improved iontophoretic bioelectrode constructed with a novel access window that conveniently allows a clinician direct access to the drug reservoir without prematurely exposing the adhesive layer. The access window is a partial cut out or perforation of a release liner that, when opened, only reveals the drug reservoir to the clinician while the remainder of the release liner simultaneously remains protectively covering the adhesive layer.
Claims15
A hydratable bioelectrode configured for delivering ions of an ionic solution comprising:
- a reservoir capable of receiving an ionic solution;
- a conductive element associated with said reservoir, said conductive element being (i) adapted for connection to a source of electrical current, and (ii) disposed so as to transfer said current through said conductive element in order to deliver said ions;
- an adhesive layer cooperatively mounted about said reservoir in order to secure said bioelectrode to a patient during use;
- a release liner covering said adhesive layer and said reservoir in order to protect said adhesive layer and said reservoir until said bioelectrode is readied for use;
- and
- an access window defined on a portion of said release liner covering said reservoir so that during preparation of said bioelectrode for use, said reservoir can be at least partially exposed by opening said access window, thereby allowing said reservoir to receive said solution without exposing said adhesive layer.
A palette having a plurality of hydratable bioelectrodes configured thereon, each said bioelectrode being configured for delivering ions of an ionic solution, each said bioelectrode comprising:
- a reservoir capable of receiving said solution;
- a conductive element associated with said reservoir, said conductive element being (i) adapted for connection to a source of electrical current, and (ii) disposed so as to transfer said current through said conductive element in order to deliver said ions;
- an adhesive layer cooperatively mounted about said reservoir in order to secure said bioelectrode to a patient during use;
- a release liner covering said adhesive layer and said reservoir in order to protect said adhesive layer and said reservoir until said bioelectrode is readied for use;
- and
- an access window defined on a portion of said release liner that is covering said reservoir so that during preparation of said bioelectrode for use, said reservoir can be at least partially exposed by opening said access window, thereby allowing said reservoir to receive said solution without exposing said adhesive layer.
In a hydratable bioelectrode configured for delivering ions of an ionic solution having a reservoir for receiving said solution, a conductive element associated therewith, an adhesive layer mounted about said reservoir, a release liner covering both said adhesive layer and said reservoir, and an access window defined on a portion of said release liner covering said reservoir, a method of using said bioelectrode, comprising the steps of:
- at least partially opening said access window without exposing said adhesive layer in order to reveal said reservoir;
- at least partially filling said reservoir with said solution.
