Abstract

The present invention relates to a method and device for non-invasive analysis of the identity and concentration of drugs that are to be administered by injection or infusion.

Claims

1-12. -12. (canceled)

13. A method to perform verification of correctness and quality assurance of a drug to be administered by injection or infusion comprising

(a) loading the drug to be administered in an administration container,

(b) coupling said administration container to an analysing unit, whereby the administration container and the analysing unit forms a closed system,

(c) in said analysing unit, non-invasively determining by spectroscopic methods one or more values of at least one chemical and/or physical property of the drug solution to generate a profile for the drug,

(d) comparing the obtained profile with a set of known profiles,

(e) if agreement between the obtained profile and the profile of the prescribed drug is reached issuing a message that the treatment is safe and administration of the drug can proceed.

14. The method according to claim 13 wherein the spectroscopic determination is performed by absorption spectrophotometry.

15. The method according to claim 14 wherein the absorption spectrophotometry is performed in a wavelength range selected from ultraviolet, visible and infrared wavelengths, preferably the ultraviolet and visible wavelengths, and more preferably the ultraviolet wavelengths.

16. The method according to claim 13 wherein the spectroscopic determination is performed by fluorescence spectroscopy or Raman spectroscopy or NMR or ESR.

17. The method according to claim 13 wherein the spectroscopic determination is performed by combining ultraviolet absorption spectrophotometry with a spectroscopic method selected from a group of spectroscopic methods consisting of visible absorption spectrophotometry, infrared absorption spectrophotometry, fluorescence spectroscopy, Raman spectroscopy, NMR, and ESR.

18. The method according to claim 13 wherein the spectroscopic determination is for identity measurements of a substance in the drug solution by obtaining a unique profile for each kind of molecule in the drug solution.

19. The method according to claim 13 wherein the spectroscopic determination is for concentration measurements by comparing the magnitude of the obtained profile with the magnitude of known concentration profiles for the substance(s) in the drug solution.

20. The method according to claim 13 wherein if an agreement is not reached between the obtained profile and the profile of the prescribed drug, a warning message is issued to stop the procedure.

21. A device for verification of correctness and quality assurance of a drug to be administered by injection or infusion comprising

a drug container or syringe, including a drug solution coupled to an analysing unit containing optical components for spectroscopic determination of at least one property of said drug solution and for issuing a signal corresponding to said property, said container and said analysing unit forming a closed system,

a central computation unit to which the signal from the analysing unit is transmitted for comparing the generated profile to a set of known profiles, and

a presentation unit for displaying the result.

22. The device according to claim 21, wherein an external information network comprising the stored set of known profiles in an external database to which the obtained profile is compared, coupled to the central computation unit.

23. The device according to claim 21, wherein the central computation unit is coupled to a patient treatment recording system.

24. The device according to claim 21, wherein the central computation unit is coupled to a treatment planning system.

25. The device according to claim 21, wherein the analysing unit comprises an ultraviolet absorption spectrophotometer optionally combined with a visible absorption spectrophotometer or an infrared absorption spectrophotometer or a fluorescence spectroscope or a Raman spectroscope or NMR or ESR.
