Abstract:
1. A method for updating software or firmware in an electronic ventilation device that comprises (i) a housing comprising an operating panel, a display, a USB interface, a hose attached to the housing through a coupling, and a respiratory gas pump installed in the housing, and (ii) a microcontroller having a rewritable memory unit for storing an updated or a previous version of the software or firmware, said method comprising: (a) providing the software or firmware for updating by an updating device; (b) communication of the ventilation device with the updating device via the USB interface; (c) when communication has been established, transmission of the update from the updating device to the ventilation device; (d) writing the update into a rewritable memory unit; (e) verification of the update as a valid version and identification of the previous version as invalid; and (f) execution of the updated software or firmware, the previous version of the software or firmware being overwritten with the updated software or firmware or being moved to a restore memory, whereby an operating program stored in the ventilation device is at least partially replaced by a new operating program; the microcontroller being driven via a data link as follows: 1. transmitting a signal to the microcontroller to reset the microcontroller; 2. providing a flash program with new firmware for writing the new firmware into the microcontroller; and 3. writing a program entry point in a well-defined location of the microcontroller, which is read-out first after completion of the reset.
