Abstract

A garment is used to facilitate the placement of biomedical sensors or other electrodes on the body. The garment is comfortable and allows freedom of movement much like typical clothing. Textile based electrical components are included in the garment which are capable of transmitting an electrical signal to and from various external electrodes placed on the body. A textile based EMI shield protects the signals from electromagnetic interference. The garment may take any form such as a vest, sports bra, long sleeve shirt, bonnet, or other form and may provide access to an electrode placement site without requiring removal of the garment.

Claims

1. An apparatus for facilitating connection of a biomedical electrode array having one or more electrodes to a monitoring, diagnostic, or stimulating device, which comprises:

a garment member for positioning relative to a body portion of a subject; and

at least one signal transmission pathway comprising a conductive thread stitched into the garment member to affix the signal transmission pathway to the garment member, the at least one signal transmission pathway having a first end terminating at an aperture that extends through the garment member and connectable to an electrode, and a second end connectable to the monitoring, diagnostic, or stimulating device, the at least one signal transmission pathway adapted for transmitting signals between the electrode and the monitoring, diagnostic, or stimulating device.

2. The apparatus according to claim 1 wherein the first end is configured to be connectable to an ECG electrode.

3. The apparatus according to claim 1 including a plurality of signal transmission pathways stitched into the garment member for transmitting signals between respective electrodes and the monitoring, diagnostic or stimulating device.

4. The apparatus according to claim 3 including a connector coupled to the first end of each of the signal transmission pathways for connection to a respective electrode.

5. The apparatus according to claim 4 wherein at least one connector is in the form of a minor lead segment.

6. The apparatus according to claim 4 wherein at least one connector is in the form of an alligator clip.

7. The apparatus according to claim 1 including an adapter associated with the second end of the at least one transmission pathway, the adapter for electrical connection to the monitoring, diagnostic or stimulating device.

8. The apparatus according to claim 7 including a tab connected to the second end of the at least one signal transmission pathway, the tab adapted for electrical connection to the adapter.

9. The apparatus according to claim 1 including a fabric layer disposed adjacent to the at least one transmission pathway on an interior of the garment member.

10. The apparatus according to claim 9 wherein the fabric layer is an EMI shield layer.

11. The apparatus according to claim 1 wherein the garment member is a shirt or vest adapted for placement about the subject'"'"'s torso.

12. The apparatus of claim 1 wherein the garment member is a sports bra.

13. The apparatus of claim 1 wherein the garment member comprises a non-conductive substrate covering intermediate segments of the conductive thread.

14. The apparatus of claim 1 further comprising a flap configured to cover at least a portion of the aperture and movable to permit access, through the aperture, to the electrode positioned on the subject'"'"'s skin.

15. The apparatus of claim 14 comprising a connector mounted to the flap and in electrical connection with the first end of one of the at least one signal transmission pathway, the connector for connection to the electrode.

16. An apparatus for connection to a biomedical electrode array having a plurality of biomedical electrodes, which comprises:

a garment member for positioning relative to a body portion of a subject and having at least one aperture providing access to one or more biomedical electrodes positionable on the subject;

a plurality of signal transmission pathways having a first end terminating at the at least one aperture, each pathway comprising a conductive thread stitched into the garment member to affix the signal transmission pathway to the garment member, and each pathway adapted to transmit an electrical signal;

a plurality of electrode connectors electrically coupled to the first ends of respective signal transmission pathways proximate to the at least one aperture, the electrode connectors adapted for connection to respective ones of the biomedical electrodes; and

an adapter for electrically coupling the signal transmission pathways to an external monitoring or stimulating device.

17. The apparatus of claim 16 including a fabric layer disposed adjacent to the at least one transmission pathway on an interior of the garment member.

18. The apparatus of claim 17 wherein the fabric layer is also disposed on an exterior of the garment to at least partially cover the transmission pathway.

19. The apparatus according to claim 18 wherein the fabric layer is an EMI shield layer.
