Abstract

An implantable microchip that is attached to a source of bodily fluids such as a vein, capillary, small artery or other fluid source such as lymph fluid or urine where the fluid flows through the microchip. The microchip can contain a micro-laboratory with reagent sources and micro-canal test chambers. The microchip can contain a readout mechanism where test data is command and/or readout to an external unit. Test results can be detected with an on-chip fluorescence or light detector or an external detector.

Claims

1. A medical diagnostic device comprising:

at least one chip component attached to a human or animal body;

at least one human bodily fluid passing through said chip component, said chip component performing tests on said bodily fluid.

2. The medical diagnostic device of claim 1 wherein said device is implanted in a human body.

3. The medical diagnostic device of claim 2 wherein said device is implanted under the skin.

4. The medical diagnostic device of claim 1 wherein said bodily fluid is blood.

5. The medical diagnostic device of claim 1 further comprising attaching a blood vessel to said device.

6. The medical diagnostic device of claim 5 wherein blood flows continuously through said device.

7. The medical diagnostic device of claim 1 wherein said device communicates the result of at least one test to a point outside said human body.

8. The medical diagnostic device of claim 1 wherein said device contains a power supply that is recharged from a point outside said human body.

9. An implantable medical test device comprising:

a plurality of attachment points for attaching said device to a source of bodily fluid wherein said fluid passes through said device, said device being attached to a human or animal body;

a plurality of test chambers on said device wherein said bodily fluid is tested according to predetermined test criteria;

at least one reagent supply on said device wherein said reagent supply supplies test reagent to said test chambers;

at least one communications module on said device whereby test results can be communicated outside said device.

10. The medical device of claim 9 further comprising micro-valves for routing said reagent to said test chambers.

11. The medical device of claim 9 wherein said predetermined test criteria include a blood glucose test.

12. The medical device of claim 9 further comprising a readout device separate from said implantable medical device, whereby said readout device reads test results from said implantable device.

13. A method of running in-vitro tests on bodily fluids comprising:

implanting a microchip in a human or animal body;

connecting said microchip to a source of bodily fluid so that said bodily fluid flows through said microchip;

sampling said bodily fluid into a test chamber on said microchip;

testing said bodily fluid according to a predetermined test criteria;

reading out test results of said testing to a device external to the body.

14. The method of claim 13 wherein said bodily fluid is blood.

15. The method of claim 13 wherein said predetermined test criteria includes testing for blood glucose level.

16. The method of claim 13 wherein said microchip contains a plurality of test chambers.

17. The method of claim 13 wherein said microchip contains at least one test reagent reservoir.

18. The method of claim 13 wherein said reading out of said test results is by means of light.

19. The method of claim 13 wherein said reading out of said test results is by means of electromagnetic energy.

20. The method of claim 17 wherein test reagent from said reagent reservoir is routed to said test chambers via micro-valves.
