  • Publication number: 20250095841
    Abstract: A method includes receiving a request to activate a medical device. Response to receiving the request, the method includes generating an automatic programming request (APR) for programming the medical device, receiving a message indicating that the APR failed to activate the medical device, and obtaining historical programming records (HPR)s. The method includes determining that parameters in the APR correspond to historical parameters, identifying a set of HPRs including a historical parameter value corresponding to a requested parameter value included the APR, and generating a deviation metric indicating a degree of difference between a secondary parameter value included in the APR and a corresponding historical parameter value. The method includes, responsive to a determination that a deviation metric meets a criticality threshold, changing a drug library record associated with the respective set of deviations and providing an indication to review the changed drug library record.

  • Publication number: 20230187063
    Abstract: A medical device is configured to store, in a session memory, data regarding operational parameters of the medical device, changes to the parameters, and physiological data of a patient associated with the medical device. A clinician may select, via a user interface of the medical device, a portion of the session memory to a remote device with a request for assistance regarding a problem occurring at the medical device. The portion of the session may be reviewed at the remote device in a graphical copy of a user interface of the medical device as it appeared when the data was recorded, and a workflow is generated at the remote device and sent to the medical device to assist the clinician in resolving issues at the medical device. A session may be started without an identification of the patient or a medical component, and the identification updated at a later time.

  • Publication number: 20230054746
    Abstract: A system and method is disclosed for converting drug library packages. An existing drug library software package is automatically analyzed to determine existing drug library information compatible with a target library format corresponding to a target medical device type, and to identify drug library information omitted, missing, or needing editing from the existing drug library information. A user interface is provided for display to convert at least a portion of the identified drug library information to the second library format, and an instruction is received via the user interface to select one or more predetermined parameters in the target library format for assignment to a new drug library software package configured in the target library format based one or more corresponding parameters selected from the identified drug library information. The new drug library software package is generated based on the existing drug library information and the selected one or more predetermined parameters.
