External defibrillator electrode, method and system for reducing ECG artifact
First Claim
1. An electrode for use with an external defibrillator for a patient, comprising:
- a monitoring segment, the monitoring segment including an electrode element, a skin preparation element configured to prepare the skin of the patient, a gel in contact with the electrode element, and a triggering mechanism;
the skin preparation element being movable relative to the electrode element in response to activation of the triggering mechanism.

Abstract
An electrode for use with an external defibrillator for a patient includes a first combination circuit including a circuit node electrically coupled to an adapter for coupling to the defibrillator. The circuit node is further coupled to a monitoring node defined by a monitoring segment of a first pad of the electrode and to a therapy node defined by a therapy segment of the first pad of the electrode. The therapy segment is electrically insulated from the monitoring segment. The first combination circuit further includes a capacitor coupled between the circuit node and the therapy node. The electrode of this disclosure hence provides additional solutions for reducing ECG artifact during the operation of the electrode.

17. An electrode for use with an external defibrillator for a patient, comprising:
-
a housing; an electrode element received by the housing; a gel received by the housing and in contact with the electrode element; a spiked frame, the spiked frame also in contact with the gel, the spiked frame defining one or more spikes along an outwardly facing side of the spiked frame, the gel received by the housing covering the outwardly facing side of the spiked frame; a spring material disposed between the housing and the spiked frame, the spring material connecting the housing to the spiked frame; and a trigger mechanism connected to the spiked frame configured for causing the spiked frame to extend outwardly from the housing against force of the spring on activation of the trigger mechanism; wherein the one or more spikes are adapted to retract back towards the housing on release of the trigger mechanism, enabling the gel to provide an electrolytic interface to the electrode element.

18. A method for monitoring a patient and delivering a charge to a patient by an external defibrillator, the method comprising the steps of:
-
activating a trigger mechanism; extending at least one spike outwardly from a monitoring segment in response to activation of the trigger mechanism; puncturing the skin of the patient with the at least one spike in response to the activation of the trigger mechanism; and electrolytically interfacing the punctured skin of the patient to an electrode element in response to the trigger mechanism. - View Dependent Claims (19)

20. A method for manufacturing an electrode for use with an external defibrillator for a patient, comprising the steps of:
-
defining a post on one side of an electrode element; defining an opening in a housing; extending the post of the electrode through the opening; attaching the post of the electrode to a monitor segment wire; attaching a spiked frame configured to puncture the skin of the patient to the housing; providing a gel on either side of the spiked frame and in contact with the electrode element; and attaching a triggering mechanism to the housing;
the spiked frame being movable relative to the electrode element in response to the triggering mechanism. - View Dependent Claims (21, 22)
