2. The method according to claim 1, wherein the associating the received patient-related data with the identified patient comprises comparing the acquisition time with a first time identified by a first one of the one or more identification time stamps.

3. The method according to claim 2, wherein the comparing the acquisition time with the first time comprises determining whether the acquisition time lies within a predetermined data acquisition time interval determined from at least the first identification time stamp, and the associating received patient-related data with an identified patient comprises associating the patient-related data with the patient identification data item if the acquisition time lies within the predetermined data acquisition time interval.

4. The method according to claim 3, wherein the data acquisition time interval is a time interval starting at the first time and having a predetermined length.

5. The method according to claim 3, wherein the data acquisition time interval extends a first predetermined period prior to the first time and a second predetermined period after the first time.

6. The method according to claim 3, wherein the receiving the set of identification data items and one or more identification time stamps comprises receiving at least the first and a second identification time stamp, the second identification time stamp identifying a second time, and wherein the data acquisition time interval is a time interval starting at the first time and ending at the second time.

7. The method according to claim 6, wherein the second time is an identification time at which one of the identification data items has been obtained.

8. The method according to claim 6, wherein the second time is a time at which a predetermined trigger event has occurred.

9. The method according to claim 2, wherein the first time is a time at which a predetermined trigger event has occurred.

10. The method according to claim 2, wherein the first time is an identification time at which one of the identification data items has been obtained.

11. The method according to claim 2, wherein the receiving the set of identification data items comprises receiving a plurality of identification data items and determining the set of identification data items from the received plurality of received identification data items as a set of identification data items associated with the first identification time stamp.

12. The method according to claim 11, wherein the determining the set of identification data items comprises determining a set of obtained identification data items from at least one of a sequential order in which the identification data items have been obtained and a relative timing of respective identification times at which the respective identification data items have been obtained.

13. The method according to claim 1, wherein each of the one or more identification time stamps is indicative of an identification time at which a respective one of the identification data items has been obtained, and

wherein associating comprises comparing a sequence of identification time stamps and a sequence of data acquisition time stamps, and identifying associated sets of identification events and data acquisition events from the comparison.

14. The method according to claim 13, wherein the identification time stamps comprise a patient identification time stamp and a device identification time stamp, the patient identification time stamp being indicative of a patient identification time at which the patient identification data item has been obtained, and the device identification time stamp being indicative of a device identification time at which the device identification data item has been obtained, and

wherein identifying associated sets of identification events and data acquisition events comprises identifying triplets of respective patient identification time stamps, device identification time stamps, and data acquisition time stamps.

15. The method according to claim 13, wherein the identification time stamps comprise a patient identification time stamp indicative of a patient identification time at which the patient identification data item has been obtained, and

wherein identifying associated sets of identification events and data acquisition events comprises identifying duplets of respective patient identification time stamps and data acquisition time stamps.

16. The method according to claim 1, wherein the set of identification data items further comprises an operator identification data item identifying an operator of the electronic device.

17. The method according to claim 1, wherein the receiving the acquisition time stamp from the electronic device further comprises receiving, from the electronic device, a control time stamp indicative of a current time determined by the electronic device, and correcting the acquisition time stamp based on a comparison of the control time stamp with a current time determined by the data processing device.

18. The method according to claim 1, wherein the receiving patient related data to be registered and an acquisition time stamp further comprises obtaining a device identifier of the electronic device from which the patient-related data is received, and

wherein the associating the received patient-related data with an identified patient is further based on the obtained device identifier of the electronic device from which the patient-related data is received.

19. A data processing system for registering patient-related data, comprising:

a communications interface configured to receive, from a registration device, a set of identification data items and one or more identification time stamps, wherein each identification time stamp is associated with at least one of the identification data items, and the set of identification data items comprises a device identification data item identifying an electronic device and a patient identification data item identifying a patient, and further configured to receive, from the electronic device, patient-related data to be registered and an acquisition time stamp indicative of an acquisition time at which the patient-related data has been acquired; and
