Embodiments include medical devices which are configured for updates in response to various events including connection of a peripheral device to the medical device, a user initiated event, or based on received recommendations.

Claims

1. A method of using a device history log of a medical device, comprising:

detecting an operable coupling of a medical device with a peripheral device and receiving identification data of the peripheral device at the medical device;

if the identification data of the peripheral device is found in the device history log, proceeding with support of the peripheral device;

if the identification data of the peripheral device is not found in the device history log, uploading support data and/or program to the medical device to support the peripheral device, and storing identification data of the peripheral device in the medical device history log;

wherein when executable code and data of the medical device are to be upgraded, downloading new code and upon initiation of the upgrade download, packing and copying the current executable code and existing data in a second nonvolatile storage area of the memory, and upon recovering from a reset, using the newly upgraded code but if a failure occurs while using the newly upgraded code, reverting to using the old unconverted data and original (not yet upgraded) code stored in the second storage memory area;

determining if the operably coupled peripheral device includes a data management program;

if the operably coupled peripheral device does not include a data management program, uploading a data management program from the medical device to the operably coupled peripheral device, the data management program having a version;

running the uploaded data management program on the peripheral device; and

further comprising comparing the version of the uploaded data management program from the medical device against a most current version of a data management program on a network and if a more current version exists on the network, uploading the more current version from the network to the peripheral device and running the more current version by the peripheral device.

2. The method of claim 1 further comprising running a first version of data and/or program on the medical device until the step of detecting the operable coupling of the peripheral device to the medical device, following which is the step of running a second version of data and/or program on the medical device, the second version being different from the first version.

3. The method of claim 2 further comprising the step of automatically reverting from running the second version of data and/or program to running the first version of data and/or program upon disconnection of the peripheral device from the medical device.

4.

5. A method of updating a peripheral device configuration, comprising:

detecting an operable coupling of a peripheral device to a medical device, the medical device being configured to provide medical data;

receiving identification data of the peripheral device in the medical device at the operable coupling;

determining if the medical device is configured to support the peripheral device by comparing the identification data of the peripheral device to a device history log stored in a memory of the medical device;

if the identification data of the peripheral device operably coupled to the medical device is found in the device history log, proceeding with support of the peripheral device;

if the identification data of the peripheral device operably connected to the medical device is not found in the device history log, uploading support data and/or program to the medical device to support the peripheral device, and storing identification data of the peripheral device in the device history log;

determining if the operably coupled peripheral device includes a data management program;

if the operably-coupled peripheral device does not include the data management program, uploading a data management program from the operably-connected medical device which is stored in a first non-volatile storage area of a memory of the medical device, to the peripheral device;

comparing a version of the uploaded data management program from the medical device against a most current version of a data management program on a network and if a more current version exists on the network, uploading the more current version from the network to the peripheral device and running the more current version by the peripheral device; and

wherein when executable code and data of the medical device are to be upgraded, downloading new code and upon initiation of the upgrade download, packing and copying the current executable code and existing data in a second nonvolatile storage area of the memory, and upon recovering from a reset, using the newly upgraded code but if a failure occurs while using the newly upgraded code, reverting to using the old unconverted data and original (not yet upgraded) code stored in the second storage memory area.

6. The method of claim 5 further comprising updating a device history log for the medical device at a manufacturing site of the medical device based on modifications to the medical device.

7. The method of claim 5 wherein communicating modifications made to the medical device to the remote location including the manufacturing site of the medical device includes one or more of a wired or a wireless communication between the medical device and the remote location.

8. The method of claim 5 further comprising the steps of running a first version of data and/or program on the medical device until the step of detecting the operable coupling of the peripheral device to the medical device at which time is the step of running a second version of data and/or program on the medical device, the second version being different from the first version.

9. The method of claim 8 further comprising the step of automatically reverting from running the second version of data and/or program to running the first version of data and/or program upon disconnection of the peripheral device from the medical device.

10. The system of claim 5 wherein if the upgrade is a critical update in which the medical device will not work properly without the critical update and a failure occurs, the step of reverting to using the old data and original code stored in the second storage area of the memory will not include making the functionality provided by the critical update accessible to a user until after a critical update is successfully installed.

11. A system including a device history log, comprising:
