  • Publication number: 20200218641
    Abstract: An inventive method for validating an end user device for use with a medical application. A medical application and a validation application are received in the end user device and the validation application is then executed, which includes: (i) determining the hardware and software environment of the end user device; (ii) providing a validation process compatible with the hardware and software environment; (iii) executing a test mode of the medical application; (iv) running the validation process during the test mode; and (v) determining from running the validation process whether the medical application is compatible with the end user device. When the medical application is determined to be compatible with the end user device, a validation report is generated and stored in the end user device and/or a server. When the medical application is determined to be incompatible with the end user device, the medical application is at least partially blocked.
