Abstract

Embodiments of the present concept are directed to external defibrillators that include an electrode connection port having multiple connection options, and include a detection device to determine an electrode connection configuration so as to provide an appropriate electrical shock to a patient. The detection device detects the electrode connection configuration of a plug connector for connected electrodes to determine if the plug connector is in an adult orientation or a pediatric orientation. The external defibrillator is configured to a deliver an electrical shock with less energy when the pediatric orientation is detected rather than the adult orientation.

Claims

1. An external defibrillator for use with electrodes having a plug connector, the external defibrillator comprising:

an energy storage module for storing an electrical charge;

a defibrillation port structured to guide via the electrodes at least a portion of the stored electrical charge to a patient;

a receiver structured to receive the plug connector of the electrodes;

a detector coupled to the receiver and structured to determine whether the plug connector is inserted into the receiver in a first orientation or the plug connector is inserted into the receiver in a different second orientation;

a processor coupled to the detector and structured to cause the defibrillation port to guide a first defibrillation energy via the electrodes when the detector determines that the plug connector is inserted into the receiver in the first orientation, and structured to cause the defibrillation port to guide a second defibrillation energy via the electrodes when the detector determines that the plug connector is inserted into the receiver in the second orientation, the first defibrillation energy greater than the second defibrillation energy.

2. The external defibrillator according to claim 1, in which

the first orientation is an adult orientation and the second orientation is a pediatric orientation.

3. The external defibrillator of claim 1, further comprising:

a user interface for outputting an indication of the detected orientation.

4. The external defibrillator of claim 1, further comprising:

a user interface illustrating how the orientation can be changed according to whether the patient is an adult or a child.

5. The external defibrillator of claim 1, in which

the receiver is a portion of the defibrillation port and includes nodes for establishing electrical contact with active pins in the plug connector.

6. The external defibrillator of claim 5, in which

the plug connector includes a first and a second of the active pins structured to establish electrical contact with a first and a second of the nodes respectively in the first orientation, and the first and the second active pins establish contact with the second and the first nodes respectively in the second orientation.

7. The external defibrillator of claim 5, in which

a first and a second of the active pins establish contact with a first and a second of the nodes respectively in the first orientation, and the first and the second active pins establish contact with the first node and a third node respectively in the second orientation.

8. The external defibrillator of claim 7, in which

the defibrillation port includes a receptacle that prevents the first active pin from being received so as to make contact with the first node or the third node.

9. The external defibrillator of claim 1, in which

the detector is structured to sense a physical portion of the plug connector for detecting whether the plug connector is connected in the first orientation or in the second orientation.

10. The external defibrillator of claim 1, in which

the detector includes at least one of a mechanical sensor, electrical sensor, electromechanical sensor, optical sensor, or magnetic sensor for detecting whether the plug connector is connected in the first orientation or in the second orientation.

11. The external electrode of claim 1, in which

a portion of the charge guided via the electrodes corresponds to a default defibrillation energy when the detector does not detect that the plug connector is connected in the first orientation or in the second orientation.

12. The external defibrillator of claim 1, in which

the plug includes at least one orientation indication pin in addition to the active pins, and

the detector is structured to detect whether the plug connector is connected in the first orientation or in the second orientation by sensing a location of the orientation indication pin with respect to the active pins.

13. The external defibrillator of claim 12, in which

the detector further includes a circuit having at least two orientation detection leads for sensing the orientation indication pin of the plug, the circuit configured to detect the first orientation when a first one of the orientation detection leads senses the orientation indication pin and configured to detect the second orientation when a second one of the orientation detection leads senses the orientation indication pin.

14. The external defibrillator of claim 13, in which

the first and second orientation detection leads are structured to sense the orientation indication pin when a circuit pathway is completed with a reference pin.
