Abstract

Apparatus for transferring electrical energy to and from living tissue comprises a glove of thin, flexible elastomeric material, which carries electrodes, electrically connected to a connector disposed at the cuff of the glove. The connector permits the electrodes to be electrically connected to a source of electrical energy or to a load, so that electrical energy may be applied to or drawn from living tissue.

Claims

1. Apparatus for selectively transferring electrical energy to and from critical localities in living tissue for diagnostic purposes, comprising a glove of flexible fluid impervious elastomeric material, said material being sufficiently thin and flexible to afford to the wearer substantially unimpeded feel and manual dexterity so as to enable use of said glove for digital palpation while transferring energy to and from tissue, and a pair of electrodes, said electrodes comprising flexible layers of electrically conductive material affixed to the surface of a finger of said glove, said electrodes being spaced from each other and electrically unconnected to each other, and disposed at areas of the glove adapted to be beneath the distal portion of the finger of a wearer of said glove, thereby to facilitate simultaneous application of said electrodes by digital direction and pressure to a palpated locality of tissue, an electrical connector coupled to said glove and adapted to be electrically connected to electrical circuitry external to said glove, and a plurality of flexible electrical conductors coupled to said glove and electrically connecting said electrodes and said connector.

2. Apparatus in accordance with claim 1, wherein said conductors comprise flexible layers of electrically conductive material affixed to the surface of said glove.

3. Apparatus in accordance with claim 2, wherein said electrodes cover areas adapted to be beneath at least approximately the palmar surface of the distal phalange of the finger of a wearer of said glove.

4. Apparatus in accordance with claim 3, wherein said electrodes comprise electrically conductive strips, elongated in an axial direction with respect to said finger of said glove to which they are affixed and generally parallel to each other.

5. Apparatus in accordance with claim 4, wherein said electrodes are disposed, when said glove is worn, on areas of the glove adapted to be on opposite sides of a sagittal plane of the finger of the user.

6. Apparatus in accordance with claim 5, wherein said electrodes are disposed on the index finger of said glove.

7. Apparatus in accordance with claim 6, wherein said flexible layers comprise woven textile cloth having electrically conductive threads therein, said electrodes and said conductors comprising strips of said cloth.

8. Apparatus in accordance with claim 1, wherein said electrodes are disposed on the index finger of said glove and cover areas adapted to be beneath at least approximately the distal phalanges of the index finger of a wearer of said glove, said electrodes comprising electrically conductive strips, elongated in an axial direction with respect to the index finger of said glove.

9. Apparatus in accordance with claim 8, wherein said electrodes are generally parallel to each other and disposed, when said glove is worn, on areas of the glove adapted to be on opposite sides of a sagittal plane of the index finger of the user.

10. Apparatus in accordance with claim 9, wherein said electrodes and said conductors comprise flexible layers of electrically conductive material affixed to the surface of said glove, said electrodes and said conductors comprising strips of said material.

11. Apparatus in accordance with claim 10, wherein said flexible layers comprise woven textile cloth having electrically conductive threads therein.

12. Apparatus in accordance with claim 11, wherein said conductors traverse the dorsal surface of said glove and are wrapped around lateral surfaces of said index finger of said glove to the palmer surface of said index finger.

13. Apparatus in accordance with claim 12, wherein said electrical connector is coupled to said glove adjacent to the cuff of said glove.

14. Apparatus in accordance with claim 13, and insulating means overlying said conductors from said electrodes to said electrical connector.

15. Apparatus in accordance with claim 14, wherein said insulating means comprises a single strip of insulating material overlying said conductors.

16. Apparatus in accordance with claim 14, wherein said insulating means comprises respective strips of insulating material overlying respective conductors.

17. Apparatus for selectively transferring electrical energy to and from critical localities in living tissue for diagnostic purposes, comprising a glove of flexible fluid impervious elastomeric material, said material being sufficiently thin and flexible to afford to the wearer substantially unimpeded feel and manual dexterity so as to enable use of said glove for digital palpation which transferring energy to and from tissue, and a plurality of electrodes, said electrodes comprising flexible layers of electrically conductive material affixed to the surface of a finger of said glove, said electrodes being spaced from each other and electrically unconnected to each other and disposed at areas of the glove adapted to be beneath the distal portion of the finger of a wearer of said glove, thereby to facilitate simultaneous application of said electrodes to a palpated locality of tissue, an electrical connector coupled to said glove and adapted to be electrically connected to electrical circuitry external to said glove, and a plurality of flexible electrical conductors coupled to said glove and electrically connecting said electrodes and said connector.
