Matrix-coded AED maintenance
View Patent ↗A status monitoring function that simplifies the process of collecting status information for medical devices in a medical device system. Matrix codes are used to associate a medical device with a location. A maintenance application transmits the association information to a centralized tracking system. Status information about the medical device is also transmitted to the centralized tracking system from the maintenance application.
1. A medical device, comprising:
a plurality of operable components, each of the operable components having a current status associated therewith, the operable components including at least a battery and a defibrillator electrode;
a processor configured to initiate a self-test of at least one of the plurality of operable components and determine a current operational status of the medical device and a current status of the at least one of the plurality of operable components based on the self-test;
a code generation component configured to automatically generate a matrix code based on the determined current operational status of the medical device and the current status of the at least one of the plurality of operable components, the matrix code encoding the current operational status of the medical device and the current status of the at least one of the plurality of operable components and the matrix code further including a non-encoded, visually interpretable indicator of the operational status of the medical device; and
a display screen configured to display the matrix code that includes status information, the status information including at least the current operational status of the medical device and the current status of at least one of the plurality of operable components.
2. The medical device of claim 1 , wherein the display screen is a low-power display screen.
3. The medical device of claim 1 , wherein the matrix code is continuously displayed on the display screen until one or more of a further self-test is performed, the current operational status of the medical device changes or the status of the at least one of the plurality of operable components changes.
4. The medical device of claim 1 , wherein the current operational status of the medical device includes at least one of a device ready status or a self-test failure status, and the current status of the at least one of the plurality of operable components includes at least one of a battery status or an electrode status.
5. The medical device of claim 1 , wherein the non-encoded, visually interpretable indicator is at least a word readable within the matrix code.
6. The medical device of claim 1 , wherein the non-encoded, visually interpretable indicator is at least one of a letter or a pictorial representation.
7. The medical device of claim 1 , wherein the matrix code further encodes a proper location associated with the medical device.
8. The medical device of claim 1 , wherein the matrix code further encodes device identification information associated with the medical device.
9. A method of displaying one or more of status of a medical device and a status of one or more of a plurality of operable components of the medical device, the method comprising:
performing at least one of a self-test or an evaluation of one or more of the medical device and at least one of the plurality of operable components;
determining one or more of a current operational status of the medical device and a status of at least one of the plurality of operable components based at least in part on the at least one of a self-test or an evaluation;
encoding in a matrix code, one or more of the current operational status of the medical device and the status of the at least one of the plurality of operable components;
adding to the matrix code, a non-encoded, visually interpretable indicator of the operational status of the medical device, the non-encoded, visually interpretable indicator included within the matrix code; and
displaying the matrix code on a display screen of the medical device.
10. The method of claim 9 , further including updating the matrix code based on one or more further self-tests or evaluations that indicate a change to one or more of the current operational status of the medical device or the current status of at least one of the plurality of operable components.
11. The method of claim 9 , further including encoding in the matrix code, a proper storage location associated with the medical device.
12. The method of claim 9 , wherein the matrix code is displayed continuously on the display screen.
13. The method of claim 9 , wherein the display screen is a low power display screen.
14. The method of claim 9 , wherein the non-encoded, visually interpretable indicator is at least one of a word readable within the matrix code, a letter within the matrix code or a pictorial representation within the matrix code.
