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.
Claims27
An external defibrillator for use with electrodes having a plug connector with at least two active pins connected to the electrodes, the external defibrillator comprising:
- an energy storage module for storing an electrical charge;
- a defibrillation port for receiving the plug connector so as to guide via the electrodes at least a portion of the stored electrical charge to a patient, the defibrillation port structured to receive the plug connector in at least one of an adult orientation and a pediatric orientation different from the adult orientation, the defibrillation port having nodes for establishing electrical contact with the active pins for guiding the charge, a certain one of the nodes establishing electrical contact with one of the active pins in each of the adult orientation and the pediatric orientation;
- an orientation detection device structured to detect whether the plug connector is connected to the defibrillation port in the adult orientation or in the pediatric orientation;
- and
- a processor for determining when to guide the electrical charge portion, and
- in which a portion of the charge corresponding to lesser defibrillation energy is guided via the electrodes if the pediatric orientation were detected than if the adult orientation were detected.
A method of determining an energy level for an electrical charge being guided from an external defibrillator to a patient through at least one electrode having a plug connector connected to a defibrillation port of the external defibrillator, the method comprising:
- detecting one of more than one possible orientations of the plug connector in the defibrillation port;
- and
- adjusting the energy level of the electrical charge guided by the external defibrillator based on the detected orientation of the plug connector.
The method of 18, in which adjusting the energy level of the electrical charge guided by the external defibrillator based on the detected orientation of the plug connector further comprises:
- adjusting the energy level of the guided electrical charge to a first level when the detected orientation of the plug connector corresponds to an adult patient;
- and
- adjusting the energy level of the guided electrical charge to a second level less than the first level when the detected orientation of the plug connector corresponds to a pediatric patient.
The method of 18, in which adjusting the energy level of the electrical charge guided by the external defibrillator based on the detected orientation of the plug connector further comprises:
- adjusting the energy level of the guided electrical charge to a default level when the detected orientation of the plug connector is not defined.
A method of operating an external defibrillator for use with electrodes having a plug connector with at least two active pins connected to the electrodes, the plug connector including at least one indication corresponding to a patient category, the method comprising:
- determining whether the patient is in an adult patient category or a pediatric patient category;
- orienting the plug connector so that the indication corresponds to the determined patient category;
- and
- inserting the oriented plug in a defibrillation port of the external defibrillator.
The method of 25, further comprising:
- confirming on a user interface of the defibrillator that the patient type corresponds to the orientation of the inserted plug connector.
The method of 25, further comprising:
- activating an operation input on the external defibrillator to guide a portion of a stored electrical charge to the connected electrodes, in which the guided portion of electrical change corresponds to the orientation of the plug connector.
