Abstract

An ECG lead system for use with a plurality of unique diverse ECG floor monitors for when a patient is substantially immobile and/or a plurality of unique diverse ECG telemetry monitors, is provided. The ECG lead system includes a plurality of unique adapters, wherein each adapter includes an input receptacle configured for selective electrical connection with a device connector of an ECG lead set assembly; and at least one unique monitor plug electrically connected to the input receptacle. Each monitor plug is configured to selectively electrically connect to a corresponding receptacle of a respective unique diverse ECG floor monitor or unique diverse ECG telemetry monitor.

Claims

1. An electrocardiograph (ECG) lead system comprising:

a first ECG lead set assembly, comprising;

a first ECG lead set cable;

a first plurality of electrode connectors disposed at a first end of the first ECG lead set cable, wherein the electrode connectors are configured to electrically connect to electrodes placed on a patient; and

a first device connector disposed at a second end of the first ECG lead set cable and configured to directly mate with, in a first configuration, an ECG lead set assembly connector of an ECG lead extension assembly and, in a second configuration, a first input receptacle of an ECG telemetry monitor adapter;

a second ECG lead set assembly, comprising;

a second ECG lead set cable;

a second plurality of electrode connectors disposed at a first end of the second ECG lead set cable, wherein the electrode connectors are configured to electrically connect to electrodes placed on a patient; and

a second device connector disposed at a second end of the second ECG lead set cable and configured to directly mate with a second input receptacle of an ECG telemetry monitor adapter;

the ECG lead extension assembly, comprising;

an ECG lead extension cable;

the ECG lead set assembly connector disposed at a first end of the ECG lead extension cable, wherein the ECG lead set assembly connector is configured and adapted to directly mate and electrically connect to the first device connector of the first ECG lead set assembly; and

a device connector disposed at a second end of the ECG lead extension cable;

an ECG floor monitor adapter, comprising;

a first input receptacle adapted and configured to directly mate with and electrically connect to the first device connector of the first ECG lead extension assembly;

a second input receptacle adapted and configured to directly mate with and electrically connect to the second device connector of the second ECG lead extension assembly; and

an ECG floor monitor plug electrically connected to the first and second input receptacles, the ECG floor monitor plug adapted and configured to directly mate with and electrically connect to a corresponding receptacle of an ECG floor monitor; and

the ECG telemetry monitor adapter, comprising;

the input receptacle adapted and configured to directly mate with and electrically connect to the device connector of the ECG lead set assembly; and

an ECG telemetry monitor plug electrically connected to the input receptacle, the ECG telemetry monitor plug adapted and configured to directly mate with and electrically connect to a corresponding receptacle of an ECG telemetry monitor.

2. The ECG lead system of claim 1, wherein each electrode connector includes:

a housing defining an aperture therein;

a lead wire terminal disposed within the housing and accessible through the aperture of the housing, wherein the lead wire terminals are electrically connectable to the electrodes placed on the patient;

a contact plate electrically connected to the lead wire terminal, the contact plate defines a keyhole slot that is in registration with the aperture of the housing, the keyhole slot includes a first slot portion and a second slot portion, wherein the first slot portion has an internal diameter which is greater than an internal diameter of the second slot portion; and

a lever pivotably connected to the housing and is biased to a first position, wherein the lever includes a cam finger projecting therefrom so as to extend across the first slot portion of the keyhole slot when the lever is in the first position.

3. The ECG lead system of claim 2, wherein the lever is actuatable to a second position wherein the cam finger does not extend across the first slot portion of the keyhole slot.

4. The ECG lead system of claim 2, wherein each electrode connector includes a biasing member disposed within the housing and operatively engaged with the lever to bias the lever to the first position.

5. The ECG lead system of claim 1, further comprising a latching system for increasing a disconnection force required to disconnect the device connector of the ECG lead set cable and the ECG lead set assembly connector of the ECG lead extension assembly.

6. The ECG lead system of claim 5, wherein the latching system includes a locking tab insertable into a recess of the device connector of the ECG lead set cable and a recess of the ECG lead set assembly connector of the ECG lead extension assembly, wherein the recesses are in registration with one another when the device connector of the ECG lead set cable and the ECG lead set assembly connector of the ECG lead extension assembly are connected to one another.

7. The ECG lead system of claim 5, wherein the latching system includes a latch arm pivotably connected to the device connector of the ECG lead set cable, wherein the latch arm is pivotable to a closed position wherein a tab extending therefrom is inserted into a recess defined in a surface of the ECG lead set assembly connector of the ECG lead extension assembly.

8. The ECG lead system of claim 5, wherein the latching system includes a pair of resilient flaps extending distally from opposed side edges of the device connector of the ECG lead set cable, wherein pair of resilient flaps project toward one another, and wherein the pair of flaps overlie a surface of the ECG lead set assembly connector of the ECG lead extension assembly when the ECG lead set assembly connector is connected to the device connector of the ECG lead set cable.

9. The ECG lead system of claim 1, wherein at least one of the ECG floor monitor plug and the ECG telemetry monitor plug has a configuration selected from the group consisting of an AAMI type (6 pin) configuration, a GE/Marquette type (11 pin) configuration, a Philips type (12 pin) configuration, a HP type (8 pin) configuration, a Spacelabs type (17 pin) configuration, a D-Subminiature type (15 pin) configuration, a D-Subminiature HP Pagewriter type (15 pin) configuration, a Datex type (10 Pin) configuration, a Medtronic type (12 pin) configuration, and a Spacelabs Dual Connect type (5 pin) configuration.
