Abstract
Electrode assemblies for applying Tumor Treating Fields (TTFields) or other types of alternating electric fields to a subject's body typically have a layer of conductive adhesive or conductive gel disposed on the front face of the electrode assembly. Incorporating glass micro-particles that contain at least one of silver, zinc, and copper into this layer or onto the front surface of this layer can provide significant sanitization benefits.
Claims20
An apparatus for applying an electrical signal to a subject's body, the apparatus comprising:
- at least one metal pad having a front face;
- a set of one or more layers of material positioned in front of the at least one metal pad, wherein the set has (a) a rear layer disposed in contact with the front face of the at least one metal pad and (b) a front layer having a front face;
- a layer of conductive adhesive or conductive gel disposed on the front face of the front layer of the set, wherein the layer of conductive adhesive or conductive gel has a front face;
- and
- at least 100 glass micro-particles disposed within the layer of conductive adhesive or conductive gel and/or disposed on the front face of the layer of conductive adhesive or conductive gel, wherein each of the at least 100 glass micro-particles contains at least one of silver, zinc, and copper.
An apparatus for applying an electrical signal to a subject's body, the apparatus comprising:
- at least one metal pad having a front face;
- a layer of conductive adhesive or conductive gel disposed on the front face of the at least one metal pad, wherein the layer of conductive adhesive or conductive gel has a front face;
- and
- at least 100 glass micro-particles disposed within the layer of conductive adhesive or conductive gel and/or disposed on the front face of the layer of conductive adhesive or conductive gel, wherein each of the at least 100 glass micro-particles contains at least one of silver, zinc, and copper.
An apparatus for applying an electrical signal to a subject's body, the apparatus comprising:
