Patient electrode connectors for electrocardiograph monitoring system
First Claim
1. An electrode connector for establishing electrical connection to a biomedical patient electrode having a stud projecting upward form a top surface thereof, the stud including a radially enlarged base, a neck, and a head, said connector comprising:
- a main connector body having a top, a bottom, and a front end portion, said front end portion defining a closed ended structure with an aperture extending through the top and bottom of said connector body;
a jaw member pivotally connected to said main body;
said main body and jaw member configurable between an open configuration and a closed configurationa biasing member engaging said main connector body and said jaw member and biasing said members to the closed configuration;
an electrically conducting plate affixed to said main connector body, said plate defining an opening, said opening in general alignment with said main body aperture;
said jaw member defining a concavity bounded by a beveled bottom edge, said beveled bottom edge functioning, upon engagement with the head of an electrode stud, to urge said jaw member toward said open configuration thereby allowing for snap attachment of the connector to the stud.

Abstract
An improved ECG electrode connector adapted for attachment to a biomedical patient electrode by either pinch or snap connection is disclosed. A closed-end electrical connector includes pair of pivotally connected members including a main connector body having an electrically conductive plate defining an electrode stud receiving aperture and disposed in proximity to the bottom surface thereof, and a jaw pivotally connected thereto and resiliently biased to a closed position. The jaw is adapted with a beveled surface that functions to urge the jaw in open by engagement of the top surface of an ECG stud thereby allowing the connector to be attached by snap engagement. The electrically conductive plate defines an irregular, generally oval-shaped opening that allows the electrode stud to be inserted through a wide portion of the opening and retained by the narrow portion of the opening. Positioning an electrically conductive plate at the bottom of the connector allows the connector to maximize electrical contact with the electrode stud. An ECG electrode connector in accordance with the present invention may further be fabricated of radiolucent materials.

6. An electrode connector for establishing electrical connection to a biomedical patient electrode having a stud projecting upward form a top surface thereof, the stud including a radially enlarged base, a neck, and a head, said connector comprising:
-
a main connector body having a top, a bottom, and a front end portion, said front end portion defining a closed ended structure with an aperture extending through the top and bottom of said connector body; a jaw member pivotally connected to said main body; said main body and jaw member configurable between an open configuration and a closed configuration; a biasing member engaging said main connector body and said jaw member and biasing said connector body and said jaw member to the closed configuration; a recessed area defined at the bottom of said main connector body and disposed in surrounding relation with said aperture; an electrically conducting plate affixed to said main connector body with at least a portion thereof disposed within said recessed area, said plate defining an opening, said opening in general alignment with said main body aperture; said jaw member defining a beveled bottom edge, said beveled bottom edge functioning, upon engagement with the head of an electrode stud, to urge said jaw member toward said open configuration thereby allowing for snap attachment of the connector to the stud; said jaw member defining a concavity and a lip projecting from said jaw member within said concavity, said lip functioning to engage the stud and urge said stud within said main body aperture such that the bottom surface of said electrically conducting plate is placed in electrical contact with the radially enlarged base of the stud. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)
