Self-contained, connected automated external defibrillator systems and methods of use
A self-contained automated external defibrillator (SCAED) system includes an AED operations block for controlling shock generation and administration, including pads for attachment to a patient, an electrocardiogram monitoring circuitry for monitoring patient heartbeat, shock generating electronics for generating electrical shock signal to be applied to the patient through the pads, a battery for supplying power to the AED operations block, a power management block for managing power consumption by the shock generating electronics and monitoring power status of the battery, a memory, a user-interface block for providing use instructions and receiving user input, and a controller for regulating the ECG monitoring circuitry, shock generating electronics, and the power management block. The SCAED system also includes a communications block for communicating with an external system separate from the SCAED system. The SCAED system further includes a security block for regulating data transfer between the AED operations block and the communications block.
1. A method for operating a self-contained automated external defibrillator (SCAED) system, the SCAED system including an AED controller for controlling electrical shock generation and delivery, a communication module for communicating with an external system separate from the SCAED system, and a security control module for performing security operations to ensure safe external communication via the communication module, the method comprising:
performing, via the security control module, a safety analysis prior to enabling electrical shock generation and delivery,
regulating data transfer between the AED controller and the communication module via the security control module,
receiving, via a user interface of the SCAED system, a request for a settings change,
checking, via the security control module, for the presence of a new settings file from a remote server,
receiving, via the security control module, the new settings file from the remote server if available,
validating, via the security control module, the new settings file,
upon validation, offering a settings change via the user interface of the SCAED system, and
upon receiving an indication for the settings change, installing the settings change to the SCAED system.
2. The method of claim 1 , wherein regulating data transfer includes:
authenticating the data so received,
validating the data so received,
upon determining that the data are authenticated and validated, transmitting the data to the AED controller, and
upon determining that the data are not authenticated or validated, providing a notification via the user interface.
3. The method of claim 2 , wherein authenticating includes at least one of using a software key, using a hardware key, and obtaining user confirmation.
4. The method of claim 2 , wherein validating includes at least one of obtaining user confirmation and assessing integrity of the data.
5. The method of claim 1 , wherein performing a safety analysis includes authenticating a user of the SCAED system.
6. The method of claim 1 , comprising:
pinging, via the security control module, a server for device updates;
obtaining an update file and validating the update file; and
upon validating the update file, transmitting the update file to the AED controller for updating the SCAED system.
7. The method of claim 1 , comprising storing, via the security control module, a copy of an existing firmware of the AED controller to enable restoration of the existing firmware if an update fails.
8. The method of claim 1 , comprising:
checking periodically, via the security control module, for the availability of a software update from a remote server;
when the software update is available, receiving an update file via the security control module;
validating, via the security control module, the update file;
saving an old file to a memory of the SCAED system; and
installing the update file.
