Abstract

A device is provided for in vivo determination of at least one blood value within an object to be examined. The device includes a catheter-shaped carrier that may be inserted into the object to be examined. The catheter-shaped carrier has at least one measuring device, of which the measurement position is arranged at a definable position of the catheter-shaped carrier, and which is designed to repeatedly determine at least one blood value and to supply this value to an evaluation unit. Moreover, a corresponding method is described for in vivo determination of at least one blood value within an object to be examined.

Claims

1. A device for in vivo determination of at least one blood value within an examination object, the device comprising:

a catheter-shaped carrier configured to be inserted into the examination object with at least one measuring device,

wherein a measuring position of the measuring device is arranged at a definable position of the catheter-shaped carrier,

wherein the measuring device is configured to determine the at least one blood value repeatedly and to supply the at least one blood value to an evaluation unit, and

wherein the catheter-shaped carrier comprises at least two openings that form at least one cohesive cavity.

2. The device as claimed in claim 1, wherein a measuring principle of the at least one measuring device is based on a spectrometric measuring principle.

3. The device as claimed in claim 1, wherein the measuring device comprises a transmitter configured to supply a blood value wirelessly to the evaluation unit.

5. The device as claimed in claim 1, wherein the catheter-shaped carrier comprises at least one integrated or insertable catheter instrument.

6. The device as claimed in claim 1, wherein the at least one measuring device is configured to determine the at least one blood value at predefinable time points.

7. The device as claimed in claim 1, wherein the evaluation unit is configured for one or more of the following:

(1) to represent the blood value on an output device, (2) to supply the blood value to a monitoring system, (3) to supply the blood value to a network, or (4) to record the blood value in a standardized data record.

15. The device as claimed in claim 2, wherein the measuring device comprises a transmitter configured to supply a blood value wirelessly to the evaluation unit.

16. The device as claimed in claim 15, wherein the catheter-shaped carrier comprises at least one integrated or insertable catheter instrument.

17. The device as claimed in claim 16, wherein the evaluation unit is configured for one or more of the following:

(1) to represent the blood value on an output device, (2) to supply the blood value to a monitoring system, (3) to supply the blood value to a network, or (4) to record the blood value in a standardized data record.

18. The device as claimed in claim 3, wherein the catheter-shaped carrier comprises at least one integrated or insertable catheter instrument.

19. The device as claimed in claim 18, wherein the evaluation unit is configured for one or more of the following:

(1) to represent the blood value on an output device, (2) to supply the blood value to a monitoring system, (3) to supply the blood value to a network, or (4) to record the blood value in a standardized data record.

20. The device as claimed in claim 3, wherein the evaluation unit is configured for one or more of the following:

(1) to represent the blood value on an output device, (2) to supply the blood value to a monitoring system, (3) to supply the blood value to a network, or (4) to record the blood value in a standardized data record.

4. (canceled)

8. A method for in vivo determination of blood values within an examination object, the method comprising:

determining at least one blood value using at least one measuring device, a measuring position of which is arranged at a definable position of a catheter-shaped carrier inserted into the examination object;

supplying the at least one blood value to an evaluation unit.

9. The method as claimed in claim 8, wherein at least one time point is predefined, at which the measurement of the at least one blood value is performed.

10. The method as claimed in claim 9, wherein the in vivo determination of at least one blood value within the examination object is performed by a device comprising a catheter-shaped carrier having at least two openings that form one cohesive cavity

11. The method as claimed in claim 10, wherein the method is executed automatically.

12. The method as claimed in claim 8, wherein the in vivo determination of at least one blood value within the examination object is performed by a device comprising a catheter-shaped carrier having at least two openings that form one cohesive cavity.

13. The method as claimed in claim 12, wherein the method is executed automatically.

14. The method as claimed in claim 8, wherein the method is executed automatically.
