Abstract

The medical terminal clip has a body member with a longitudinal axis and a pair of laterally spaced leg members extending in approximately the longitudinal direction and pivotally connected for relative movement. The respective spaced leg members form a variably spaced electrode receptacle on one side of the pivotal connection. A beryllium copper conductive member is embedded in the body member and is formed from a strip of metal bent into approximately an M-shape with side flanges on the leg members to provide additional strength. A shield or barrier member extends at least between the approximate ends of the leg members on the other side of the pivotal connection while permitting relative movement of the leg members. The shield member is designed to close longitudinal access to the space between the leg members and thereby prevent any dislocation of the terminal clip member by catching onto exterior objects such as other terminal wires.

Claims

1. A medical terminal clip member for attachment to electrodes connected to a patient comprising;

a body member made out of a relatively soft plastic material having a longitudinal axis and a pair of laterally spaced leg members extending in an approximately longitudinal direction and pivotally connected for relative movement, the spaced leg members forming a variably spaced electrode receptacle on one side of the pivotal connection;

conductive means supported by the body member and strengthening each laterally spaced leg member and further electrically connected to the electrode receptacle includes an approximately U-shaped receptacle and a pair of side members connected to and extending respectively from each end of the receptacle, each side member including a flange, and

a flexible shield member having a greater width along the longitudinal axis than its thickness traverse to the longitudinal axis is formed from the plastic material, the shield member further has a recessed central crease extending along the longitudinal direction so as to form an approximately shallow V-shape in a plane traverse to the longitudinal axis whereby either side of the flexible shield member pivots about the crease and come closer together when the respective leg members are depressed to open the electrical receptacle cavity, the flexible shield closes longitudinal access to the space between the leg members to prevent dislocation of the terminal clip member from the electrode by catching onto an exterior object.

2. The invention of claim 1 wherein the side member flanges project inward towards each other.

3. The invention of claim 1 wherein the body member, leg members and flexible shield members are formed from a polyvinyl chloride plastic.

4. The invention of claim 1 wherein the approximate vertical height of the U-shaped receptacle is about twice the vertical height of the side members.

5. The invention of claim 4 wherein the conductive means includes a single strip of metal bent into approximately an M shape.

6. The invention of claim 5 wherein the conductive means is a single strip of beryllium copper.

7. The invention of claim 1 wherein the conductive means supported by the body member and leg members includes an approximately M-shaped conductive member, the upper portion of the M being exposed in the electrode receptacle cavity and forming an electrode receptacle for electrical connection and the side members embedded in the plastic leg members and extending beyond the pivotal connection and being contained respectively in each leg member, only the side members being cut and bent to form respective lateral flanges for providing additional strength to each leg member.

8. The invention of claim 7 wherein the vertical height of the upper portion of the M electrode receptacle is greater than the vertical height of the side members.

9. The invention of claim 7 wherein the approximately M-shaped conductive member is formed from a single strip of beryllium copper.

10. The invention of claim 7 wherein the plastic body member, plastic leg members and flexible shield member are molded from a polyvinyl chloride plastic.

11. The invention of claim 7 wherein the lateral flanges on each side member project inward towards each other.
