Abstract

For repeatedly measuring signals from the same part of the tissue to monitor the blood composition, we use elastic membranes at upper and lower parts of the intruded tissue together with a cone-shaped guide. This will constrain the tissue in the same place when the signal guide is used for measuring the signals from the same part of tissue repeatedly. The signals can be from the aggregate of the designated composition with the other ingredients of the blood. For example, we may use the signals from the precursor of Glycated hemoglobin (HbAlc) to measure the concentration of blood glucose. For bio-secure purpose, the cone-shaped guide will be extended to cover tightly most part of the finger.

Claims

1. An apparatus for monitoring a signal from a tissue in situ comprising:

a tissue adaptor to fix the tissue at the same place during repeated measurements;

a signal producer; and

a signal analyzer;

wherein the signal produced by the signal producer is interacted with the tissue and then be measured by the signal analyzer.

2. An apparatus as claimed in claim 1, wherein the said signal producer comprises a signal generator outside the tissue and interacts with the tissue to create the signal producer.

3. An apparatus as claimed in claim 1, wherein the said signal producer is in the tissue.

4. An apparatus as claimed in claim 1, wherein the tissue comprises an extrude shape.

5. An apparatus as claimed in claim 4, wherein the said extrude shape comprises a finger.

6. An apparatus as claimed in claim 1, wherein the said tissue adaptor comprises a soft pad.

7. An apparatus as claimed in claim 6, wherein the said soft pad is above the tissue.

8. An apparatus as claimed in claim 6, wherein the said soft pad is below the tissue.

9. An apparatus as claimed in claim 4, further comprising a cone shaped guide to confine the tissue.

10. An apparatus as claimed in claim 4, further comprising a concaved structure fit closely to the extruded tissue.

11. An apparatus as claimed in claim 2, wherein the said signal outside the tissue comprises electromagnetic wave.

12. An apparatus as claimed in claim 1, wherein the said signal producer comprises an ingredient in the tissue.

13. An apparatus as claimed in claim 12, wherein the said ingredient comprises an aggregate.

14. An apparatus as claimed in claim 13, wherein the said aggregate comprises glucose.

15. An apparatus as claimed in claim 13, wherein the said aggregate comprises hemoglobin.

16. An apparatus as claimed in claim 13, wherein the said aggregate comprises glucose and hemoglobin.

17. An apparatus as claimed in claim 1, wherein the said tissue adaptor comprises a flat area.

18. An apparatus as claimed in claim 1, wherein the said tissue adaptor comprises a spring.

19. An apparatus as claimed in claim 1, wherein the said tissue adaptor comprises an elastic membrane.

20. An apparatus as claimed in claim 1, wherein the said elastic membrane is above the tissue.

21. An apparatus as claimed in claim 1, wherein the said elastic membrane is below the tissue.

29. An apparatus as claimed in claim 9, wherein the cone shaped guide is extended to cover tightly some part of the finger.

22. An apparatus for measuring a specific ingredient in blood comprises:

a signal generator; and

an analyzer to analyze the signal from the aggregate of said ingredient to determine the concentration of said ingredient.

23. An apparatus as claimed in claim 22, wherein the said blood comprises the signal generator.

24. An apparatus as claimed in claim 23, wherein said signal generator is generated from a signal from outside the blood and interactes with the blood to generate the signal.

25. An apparatus as claimed in claim 22, wherein the said specific ingredient comprises glucose.

26. An apparatus as claimed in claim 25, wherein the said glucose aggregate comprises hemoglobin.

27. An apparatus as claimed in claim 22, wherein the said signal from said aggregate comprises electromagnetic wave.

28. An apparatus as claimed in claim 22, wherein the said signal from the said aggregate comprises radiations.
