Abstract

A unitary ECG monitor lead and needle electrode system includes a connector for connection to an ECG monitor junction; an electrode lead interconnected with the connector at one end of the electrode lead, the lead including a signal conductor; and a needle electrode unit interconnected with the other end of the electrode lead and including a needle electrode, a body portion for receiving the other end of the lead and for receiving an electrode needle, for forming the needle electrode unit as a single integral unit.

Claims

1. An ECG monitoring system comprising:

an ECG monitor;

a plurality of needle electrode systems each comprising;

a connector connecting to an ECG monitor junction,

a single integral needle electrode unit, and

a lead connecting said connector with said needle electrode unit forming said needle electrode system as a single integral unit, said lead including a signal conductor;

said connector having female sockets and a first end of said signal conductor, said single integral needle electrode unit comprising;

a body portion, and

an electrode needle extending from said body portion and being molded into said body portion for permanently attaching the electrode needle in the body portion, a second end of said signal conductor electrically contacting said needle within said body portion, wherein said electrode needle can be inserted in the body of a patient to convey ECG signals from the patient to the ECG monitor.

2. The system of claim 1 in which said needle electrode is hollow, the second end of said signal conductor extending partially within said hollow needle.

3. The system of claim 1 in which said lead further includes a shield surrounding said signal conductor, a first end of said shield in said connector, a second end of said shield terminating within said body portion.

4. The system of claim 1 in which said connector is integrally formed with said lead.

5. The system of claim 1 in which said body portion is integrally formed with said lead.
