Repair or refurbishment of limited use medical devices
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 medical device comprising:
an electrically powered medical device;
a connector that connects the medical device to an external device;
a first electronic component electrically connected to the medical device, the first electronic component performing a first function when the medical device is connected to the external device a first time, and the first electronic component being disabled from performing the first function when the medical device is connected to the external device a subsequent time;
a second electronic component electrically connected to the medical device, the second electronic component performing the first function when the medical device is connected to the external device the subsequent time.
2. The medical device of claim 1 , wherein:
the connector comprises a plug; and
the second electronic component is electrically connected with the connector.
3. The medical device of claim 1 , wherein the first electronic component is a fuse.
4. The medical device of claim 3 , wherein the second electronic component is a fuse.
5. The medical device of claim 1 , wherein the first electronic component comprises non-volatile memory.
6. The medical device of claim 5 , wherein the second electronic component comprises non-volatile memory.
7. The medical device of claim 1 , wherein the external device comprises a generator.
8. The medical device of claim 1 , wherein the external device comprises a power supply.
9. The medical device of claim 1 , wherein the external device comprises a measuring apparatus.
10. The medical device of claim 1 , wherein the first electronic component is embedded in the medical device.
11. The medical device of claim 1 further comprising a plug, wherein the plug comprises the connector, and wherein the first electronic component is embedded in the plug.
12. The medical device of claim 11 , wherein the second electronic component is inserted into the plug.
13. The medical device of claim 1 , wherein the second electronic component is not connected with the connector when the medical device is connected to the external device the first time.
14. The medical device of claim 13 , wherein the second electronic component is connected with the connector after the medical device is connected to the external device the first time.
15. The medical device of claim 1 , wherein the second electronic component is connected with the connector when the medical device is connected to the external device the subsequent time.
16. The medical device of claim 1 ,
wherein the second electronic component is functionally equivalent to a non-disabled first electronic component.
17. The medical device of claim 16 , wherein the first electronic component is positioned inside a body of the plug.
18. The medical device of claim 16 , wherein the first electronic component is positioned inside a body of the medical device.
19. The medical device of claim 16 , wherein the second electronic component is positioned inside an opening of the plug.
20. The medical device of claim 16 , wherein the second electronic component is positioned inside a body of the medical device.
