Abstract

The invention provides a device and methods for analysing body fluids wherein the device is implanted in the body and provides for both the delivery of substances into the body and for the testing of body fluids.

Claims

1. A method of testing body fluids and introducing a medicament comprising:

permanently implanting a port body into a body, the port body having a selectively accessible exposed portion external to the body, an aspiration tube depending from the port body and in contact with a source of body fluids, and a feed tube depending from the port body;

passing a medicament through the selectively accessible exposed portion and into the feed tube, wherein the medicament is introduced to the body upon exiting the feed tube; and

aspirating body fluids in the aspiration tube wherein the body fluids are tested to determine presence and/or concentration of an element within the body fluid.

2. The method of claim 1, wherein the selectively accessible exposed portion is a self closing diaphragm.

3. The method of claim 1, wherein passing a medicament further comprises introducing a feed catheter through the selectively accessible exposed portion.

4. The method of claim 1, wherein aspirating body fluids further comprises introducing an aspirating catheter through the selectively accessible exposed portion and passing the aspirating catheter through the aspirating tube until the aspirating catheter contacts body fluids.

5. The method of claim 4, wherein the body fluids are extracted from the body through the aspirating catheter so that the testing of the body fluids is performed external to the body.

6. The method of claim 1 wherein the body fluids are tested within the aspiration tube.

7. The method of claim 1, wherein the port body is suitable as a permanent means of access for passing a medicament.

8. The method of claim 7, wherein the medicament is insulin.

9. The method of claim 1, wherein implanting the port body into the body comprises implanting the port body into the umbilical vein.

10. The method of claim 1, further comprising introducing a sensor into the aspiration tube for testing the body fluid.

11. The method of claim 10, wherein the sensor is introduced at an intermediate point of the aspiration tube.

12. The method of claim 10, wherein the sensor is introduced in the aspiration tube in a manner to remain permanently in the aspiration tube.

13. The method of claim 10, wherein the sensor is an electronic test sensor.

14. The method of claim 10, wherein the sensor is a one-time use probe.

15. The method of claim 1, further comprising introducing a sensor to the interior of the body through the aspiration tube.

16. The method of claim 1, wherein the port body further comprises a shaft portion to which an anchoring section may be attached for stabilizing the port body.

17. The method of claim 16, wherein the anchoring section stabilizes the port body in skin.

18. The method of claim 16, wherein the anchoring section stabilizes the port body under skin.

19. The method of claim 16, wherein the shaft section forms a hollow enclosure suitable for supporting an elastic self-closing diaphragm.

20. The method of claim 1, wherein the aspiration tube is shorter in length than the feed tub.

21. A method of testing body fluids and introducing a medicament comprising:

semi-permanently implanting a port body into a body, the port body having a selectively accessible exposed portion external to the body, an aspiration tube depending from the port body and in contact with a source of body fluids, and a feed tube depending from the port body;

passing a medicament through the selectively accessible exposed portion and into the feed tube, wherein the medicament is introduced to the body upon exiting the feed tube; and

aspirating body fluids in the aspiration tube wherein the body fluids are tested to determine presence and/or concentration of an element within the body fluid.

22. The method of claim 21, wherein the selectively accessible exposed portion is a self closing diaphragm.

23. The method of claim 21, wherein passing a medicament further comprises introducing a feed catheter through the selectively accessible exposed portion.

24. The method of claim 21, wherein aspirating body fluids further comprises introducing an aspirating catheter through the selectively accessible exposed portion and passing the aspirating catheter through the aspirating tube until the aspirating catheter contacts body fluids.

25. The method of claim 24, wherein the body fluids are extracted from the body through the aspirating catheter so that the testing of the body fluids is performed external to the body.

26. The method of claim 21 wherein the body fluids are tested within the aspiration tube.

27. The method of claim 21, wherein the port body is suitable as a semi-permanent means of access for passing a medicament.

28. The method of claim 27, wherein the medicament is insulin.

29. The method of claim 21, wherein implanting the port body into the body comprises implanting the port body into the umbilical vein.

30. The method of claim 21, further comprising introducing a sensor into the aspiration tube for testing the body fluid.

31. The method of claim 30, wherein the sensor is introduced at an intermediate point of the aspiration tube.

32. The method of claim 21, wherein the port body further comprises a shaft portion to which an anchoring section may be attached for stabilizing the port body.
