Precordial electrocardiogram electrode connector

An electrocardiogram (ECG) electrode connector for electrically connecting a plurality of electrode contacts on an electrode mask to an EGG device, comprising:

• a base portion, the base portion having an electrode end, an EGG end, a top surface, and a lower surface wherein a locator pin is located on a surface of the base portion at the electrode end;
• an upper portion pivotally connected to the base portion, the upper portion having an electrode end and an EGG end, wherein the upper portion electrode end includes an indentation suitably sized to surround the locator pin on at least one side thereof
• a spring between the base portion and the upper portion to bias the electrode ends of the base portion and upper portion together;
• an electrical assembly to provide electrical continuity between the electrode contacts and the EGG device;
• and
• first and second sides extending upwardly from the base portion, wherein the upper portion at least partially fits in between the first and second raised sides.

An electrocardiogram (EGG) electrode system comprising:

• an electrode mask having a plurality of electrode contacts thereon;
• an EGG device for processing EGG signals sensed by the electrode mask;
• and
• an electrode connector for electrically connecting individual ones of plurality of electrode contacts to the EGG device, the electrode connector comprising:
• a base portion having an electrode end, an EGG end, a top surface, and a lower surface;
• an upper portion pivotally connected to the base portion, the upper portion having a top surface, a lower surface, an electrode end, and an EGG end;
• a spring between the base portion and the upper portion to bias the electrode ends of the base and upper portions together to clamp the electrode mask;
• an electrical assembly comprising an elastomeric electrical connector;
• and
• a plurality of protrusions extending from the upper portion lower surface, each of the protrusions collocated with at least a portion of the elastomeric connector and with at least one of the plurality of electrode contacts,
• wherein electrical continuity is provided between individual ones of the plurality of electrode contacts and the EGG device when the electrode ends of the lower portion and the upper portion of the connector are biased together.

A method of using a bias-closed connector to connect an electrode mask to an ECG device, the method, comprising:

• providing an electrode mask having a plurality of sizing holes;
• selecting one of the sizing holes based upon a patient's size;
• inserting a connecting portion of the mask in the electrode connector by manually opening the connector and fitting the selected sizing hole to a pin located on a surface of the connector;
• and
• closing the connector by releasing the ends so that the mask is held within the connector at least in part by the pin and an indentation formed on the connector.
