Repair or refurbishment of limited use medical devices
View Patent ↗A powered medical device includes electronic components on a circuit board embedded within the body of a plug for connecting the device with a control apparatus. The medical device may be repaired or refurbished without the need to access the embedded circuit board through the use of a supplemental circuit board installed into the open end of the plug adjacent the plug pins. The supplemental circuit board may include a variety of electronic components, including fuses or non-volatile memory.
1. A refurbished medical device comprising:
a plug adapted to connect the medical device to a device controller;
a connector positioned at a surface of the plug;
a first electronic component adapted to perform a first function and electrically connected with the connector, the first electronic component having been disabled from performing the first function;
a supplemental circuit board attached to the plug and electrically connected with the connector; and
a second electronic component adapted to perform the first function and secured by the supplemental circuit board and electrically connected with the connector, the second electronic component being capable of performing the first function.
2. The medical device of claim 1 , wherein the first electronic component is a fuse.
3. The medical device of claim 2 , wherein the second electronic component is a fuse.
4. The medical device of claim 1 , wherein the electronic component comprises non-volatile memory.
5. The medical device of claim 4 , wherein the second electronic component comprises non-volatile memory.
6. The medical device of claim 1 , wherein the plug comprises an open end.
7. The medical device of claim 6 , wherein the plug open end comprises a shield that surrounds the plug surface at which the connector is positioned.
8. The medical device of claim 6 , wherein the connector is a pin that extends within the open end of the plug.
9. The medical device of claim 6 , wherein the supplemental circuit board is inserted into the open end of the plug.
10. The medical device of claim 9 , wherein the supplemental circuit board is positioned adjacent the plug surface at which the connector is positioned.
11. The medical device of claim 1 , wherein the supplemental circuit board comprises a through hole.
12. The medical device of claim 11 , wherein the supplemental circuit board through hole encircles the connector.
13. The medical device of claim 11 further comprising an interference fit between the through hole and the connector.
14. The medical device of claim 1 , wherein the supplemental circuit board comprises a conductive track and a non-conductive substrate.
15. The medical device of claim 14 , wherein the second electronic component is attached to a surface of the supplemental circuit board.
16. The medical device of claim 1 , wherein the second electronic component is embedded at least partially within supplemental circuit board.
17. The medical device of claim 16 , wherein the supplemental circuit board comprises an injection molded structure.
18. A medical device comprising:
a plug adapted to connect the medical device to a device controller;
a connector positioned at a surface of the plug;
a first electronic component electrically connected with the connector, the first electronic component being functionally disabled;
a supplemental circuit board attached to the plug and electrically connected with the connector;
a second electronic component attached to the supplemental circuit board and electrically connected with the connector;
wherein the second electronic component is functionally equivalent to a non-disabled first electronic component.
19. The medical device of claim 18 further comprising a second connector extending from a surface of the plug.
20. The medical device of claim 19 , wherein the second electronic component is electrically connected between the first connector and the second connector.
