Abstract

A method and an apparatus are disclosed for checking parameters provided for an examination of a patient with the aid of a contrast medium in a contrast medium injector. The parameters are automatically checked for their medical safety for the patient by taking account of at least one individual datum of the patient with the aid of at least one test criterion, and at least one of a warning signal is output, and/or the operation of the contrast medium injector is stopped when a health risk for the patient is determined.

Claims

1. A method for checking parameters provided for an examination of a patient with the aid of a contrast medium in a contrast medium injector, the method comprising:

automatically checking the parameters for medical safety for the patient by taking account of at least one individual datum of the patient with the aid of at least one test criterion; and

at least one of outputting a warning signal and stopping operation of the contrast medium injector, when a health risk for the patient is determined based upon the automatic checking.

2. The method as claimed in claim 1, wherein the parameters for the contrast medium injector include at least one of a type of the contrast medium, a volume of contrast medium to be injected, a maximum flow rate of the contrast medium, and an injection period of the contrast medium.

3. The method as claimed in claim 1, wherein the test criteria is fixable by a user.

4. The method as claimed in claim 1, wherein the test criteria generally comprise at least one of age, body size and rules that take account of weight of the patient.

5. The method as claimed in claim 4, wherein, in accordance with one or more test criteria, only a specific maximum volume of contrast medium is injectable, per examination, into a patient as a function of at least one of age, body size, weight and body mass index.

6. The method as claimed in claim 4, wherein at least one of the body size and the weight of the patient are determined from a topogram of the patient obtained with the aid of an X-ray computer tomograph.

7. The method as claimed in claim 4, wherein, in accordance with a test criterion, the flow rate of the contrast medium can exceed a specific maximum value as a function of the age of the patient.

8. The method as claimed in claim 1, wherein the test criteria include prior medical knowledge of the patient.

9. The method as claimed in claim 8, wherein the prior medical knowledge of the patient includes information relating to previous examinations with at least one of the aid of contrast media, knowledge of contrast medium allergies and physical problems.

10. The method as claimed in claim 1, wherein the test criteria include general prior medical knowledge of contrast media.

24. The method as claimed in claim 2, wherein the test criteria is fixable by a user.

25. The method as claimed in claim 2, wherein the test criteria generally comprise at least one of age, body size and rules that take account of weight of the patient.

26. The method as claimed in claim 25, wherein, in accordance with one or more test criteria, only a specific maximum volume of contrast medium is injectable, per examination, into a patient as a function of at least one of age, body size, weight and body mass index.

31. A computer readable medium including program segments for, when executed on a computer device, causing the computer device to implement the method of claim 1.

11. An apparatus for checking parameters provided for examination of a patient with the aid of a contrast medium in a contrast medium injector, the apparatus comprising:

a contrast medium injector; and

a computation device to automatically check the parameters for medical safety for the patient by taking account of at least one individual datum of the patient with the aid of at least one test criterion, the computation device further being useable to generate at least one of an outputtable warning signal and a control signal that stops the operation of the contrast medium injector, when a health risk for the patient is determined based upon the automatic checking.

12. The apparatus as claimed in claim 11, wherein the parameters for the contrast medium injector include at least one of a type of contrast medium, a volume of contrast medium to be injected, a maximum flow rate of the contrast medium, and an injection period of the contrast medium.

13. The apparatus as claimed in claim 11, wherein the test criteria is fixable by a user with the aid of at least one input device connected to the computation device.

14. The apparatus as claimed in claim 11, wherein the test criteria generally comprise at least one of age, body size and rules that take account of the weight of the patient.

15. The apparatus as claimed in claim 14, wherein, in accordance with one or more test criteria, only a specific maximum volume of contrast medium, per examination, is injectable into a patient as a function of at least one of age, body size, weight and body mass index.

16. The apparatus as claimed in claim 14, wherein, in accordance with a test criterion, flow rate of the contrast medium can exceed a specific maximum value as a function of the age of the patient.

17. The apparatus as claimed in claim 11, wherein the test criteria include prior medical knowledge of the patient that is stored in a patient file.

18. The apparatus as claimed in claim 17, wherein the prior medical knowledge of the patient includes at least one of information relating to previous examinations with the aid of contrast media, knowledge of contrast medium allergies and physical problems.

19. The apparatus as claimed in claim 11, wherein the test criteria include general prior medical knowledge of contrast media.

20. The apparatus as claimed in claim 11, wherein the computation device is part of the contrast medium injector.

21. The apparatus as claimed in claim 11, wherein the computation device is part of an imaging medical appliance connected to the contrast medium injector.

22. The apparatus as claimed in claim 21, wherein the imaging medical appliance is at least one of an X-ray machine, an X-ray computer tomograph, a C-arc X-ray machine, an ultrasound appliance and a magnetic resonance appliance.

23. The apparatus as claimed in claim 22, wherein at least one of body size and weight of the patient is determinable from a tomogram of the patient obtained with the aid of an X-ray computer tomograph.

27. The apparatus as claimed in claim 12, wherein the test criteria is fixable by a user with the aid of at least one input device connected to the computation device.

28. An apparatus for checking parameters provided for an examination of a patient with the aid of a contrast medium in a contrast medium injector, the apparatus comprising:

means for automatically checking the parameters for medical safety for the patient by taking account of at least one individual datum of the patient with the aid of at least one test criterion; and

means for at least one of outputting a warning signal and stopping operation of the contrast medium injector, when a health risk for the patient is determined based upon the automatic checking.

29. The apparatus as claimed in claim 28, wherein the imaging medical appliance is at least one of an X-ray machine, an X-ray computer tomograph, a C-arc X-ray machine, an ultrasound appliance and a magnetic resonance appliance.

30. The apparatus as claimed in claim 29, wherein at least one of body size and weight of the patient is determinable from a tomogram of the patient obtained with the aid of an X-ray computer tomograph.
