Abstract

A method and system for wireless ECG monitoring is provided. An electrode connector, transmitter and receiver operate with existing electrodes and ECG monitors. The electrode connector includes connectors for attaching to disposable or reusable single electrodes. The transmitter transmits the signals from the electrodes to the receiver. The receiver passes the electrode signals to the ECG monitor for processing. ECG monitors used with an electrical conductor, for example wire connections to electrodes, are connected with the receiver, avoiding the purchase of a new monitor. Any legacy ECG monitor, including different ECG monitors, connects with the receiver using the ECG monitor'"'"'s lead-wires. The ECG monitor operates as if directly connected to the electrodes without the problems discussed above associated with wires running from the ECG monitor to the patient.

Claims

1. An electrode connector for physiological monitoring of a patient, the connector comprising:

material operable to interconnect a plurality of electrodes; and

a plurality of electrode connectors provided on the material, the connectors being releasable and rejoinable;

wherein the material comprises a plurality of arms, each of the plurality of arms corresponding to respective ones of the plurality of electrode connectors and wherein the plurality of arms are configured relative to each other to aid in positioning the plurality of electrode connectors on the patient.

2. The electrode connector of claim 1 wherein the electrode connectors are adapted to withstand the electrical energy produced by a defibrillator used on the patient.

3. The electrode connector of claim 1 wherein the plurality of arms comprise at least four arms associated with hexaxial electrodes, the at least four arms connected at angles to each other, the angles corresponding to relative hexaxial positions on the patient.

4. The electrode connector of claim 1 wherein each of the plurality of arms include an electrical conductor.

5. The electrode connector of claim 4 wherein each of the electrical conductors electrically connects with the respective electrode connector.

6. The electrode connector of claim 1 wherein at least a first of the plurality of arms corresponds to a hexaxial electrode position and at least a second of the plurality of arms corresponds to a precordial electrode position, the first and second arms being connected such that each of the first and second arms is disposed towards the corresponding electrode positions.

7. The electrode connector of claim 6 wherein the second arm connects to the first arm.

8. The electrode connector of claim 1 further comprising a belt, and wherein at least one of the plurality of arms is expandable, the at least one expandable arms connecting with the belt.

9. The electrode connector of claim 8 wherein a first arm comprises a hexaxial electrode arm connected with the belt and a second arm comprises a hexaxial and precordial electrode arm connected with the belt, the first and second arms connected with the belt such that the first arm extending from the belt to a first hexaxial electrode position avoids intersection with the second arm extending from the belt to a second hexaxial and a first precordial electrode positions.

10. The electrode connector of claim 1 wherein each of the plurality of arms extends from a central position to corresponding electrode positions without intersection, each of the plurality of arms being extendable and comprising a memoryless material.

11. The electrode connector of claim 1 further comprising a releasable arm connector on at least one of the plurality of arms, the releasable arm connector spaced away from at least one of the plurality of electrode connectors associated with the one arm.

12. A method for connecting electrodes for ECG monitoring, the method comprising the acts of:

(a) placing a plurality of electrodes onto a patient in preselected positions;

(b) positioning a plurality of arms, one arm provided for each of the plurality of electrodes, the plurality of arms connected or connectable relative to each other to align with the preselected position of each of the plurality of electrodes;

(c) connecting the plurality of arms to the plurality of electrodes, respectively; and

(d) connecting a precordial-lead arm with a hexaxial-lead expandable arm.
