ECG leadwire system with noise suppression and related methods
First Claim
1. A noise-suppressing ECG adapter, comprising:
- a housing having a first end and a second end;
at least one first connector disposed at the first end of the housing, the at least one first connector adapted for operably coupling to a proximal end of an ECG lead set;
at least one second connector disposed at the second end of the housing, the at least one second connector adapted for coupling to an input of an ECG device;
a noise suppression element disposed within the housing, the noise suppression element including one of a ferromagnetic element and an electromagnet having an opening defined therein; and
at least one conductor operably coupling the first connector and the second connector and passing through the opening of the one of the ferromagnetic element and the electromagnet,wherein the noise suppression element includes the ferromagnetic element formed from material selected from the group consisting of ferrite and laminated iron.

Abstract
A noise-suppressing electrocardiograph (ECG) adapter having a first end, a second end, and a noise-suppression element is presented, together with an ECG noise-suppressing system and related methods. In an embodiment, the noise-suppressing ECG adapter includes a housing having at least one first connector disposed at a first end of the housing adapted to electrically couple with an ECG lead set, and at least one second connector adapted for coupling to an input of an ECG device. The adapter includes a noise suppression element. The noise suppression element includes a ferromagnetic element having an opening defined therein. In an embodiment the noise suppression element is internal to the adapter. In another embodiment, the noise suppression element is tethered externally to the adapter and configured to clamp around at least a portion of an ECG leadwire.
