Abstract

The invention relates to a system of a plurality of medical treatment units that are respectively associated with a patient, and a plurality of peripheral appliances also respectively associated with a patient. The peripheral appliances transmit control signals and patient signals to the treatment units, while the treatment units receive the control signals and patient signals from the peripheral appliances. The present invention ensures that the treatment units do not receive patient signals from other peripheral appliances that are not associated with the particular patient. The operating staff allocate a peripheral appliance to a patient and confirm the successful association of the peripheral appliance with the treatment unit allocated to the patient.

Claims

1-12. -12. (canceled)

13. A system for matching multiple peripheral devices and medical treatment units with the correct patient comprising:

a plurality of peripheral devices and a plurality of medical treatment units, each medical treatment unit and each peripheral device being allocated to a single patient, each peripheral device comprising;

a control signal sending means for sending control signals to a treatment unit,

a patient signal sending means for sending patient signals to a treatment unit,

a first monitoring means for monitoring the allocation of the peripheral device to a patient, and

log-on means for logging onto the peripheral device with a treatment unit, said log-on means cooperating with the control signal sending means and the first monitoring means, and

each medical treatment unit comprising;

a control signal receiving means for receiving control signals from a peripheral device,

a patient signal receiving means for receiving patient signals from a peripheral device,

an acknowledgement means for inputting the acknowledgement of a successful allocation of a peripheral device to a treatment unit, and

a second monitoring means for monitoring the allocation of a peripheral device to the treatment unit, said second monitoring means cooperating with the control signal receiving means, the patient signal receiving means, and the acknowledgement means,

wherein when a successful allocation of the peripheral device to a patient has taken place, a log-on signal is sent to the respective treatment unit allocated to the patient;

wherein after a log-on signal has been received from the peripheral device, a check is made to establish whether a successful allocation of the peripheral device to the treatment unit has been acknowledged, and

wherein when a successful allocation of the peripheral device to the treatment unit has been acknowledged, the patient signal receiving means are activated.

14. The system of claim 13, wherein the second monitoring means comprises a timing element with a preset timing constant which is started after the log-on signal has been received, and the check is made to establish whether a successful allocation of a peripheral device to a treatment unit has been acknowledged within the preset timing constant.

15. The system of claim 14, wherein the patient signal receiving means are not activated if the log-on signals are received from more than one peripheral device within the preset timing constant.

16. The system of claim 13, wherein the second monitoring means comprises comparison means for comparing an identification signal of a peripheral device with a reference signal of the treatment unit allocated to the peripheral device, said comparison means cooperating with the patient signal receiving means to activate the patient signal receiving means when the identification signal and the reference signal match.

17. The system of claim 13, wherein the peripheral device comprises a peripheral device storage means for storing an identification signal.

18. The system of claim 13, wherein the log-on means cooperate with the control signal sending means to send an identification signal of the peripheral device together with the log-on signal to the treatment unit.

19. The system of claim 13, wherein the treatment unit comprises a treatment unit storage means for storing an identification signal.

20. The system of claim 13, wherein first monitoring means comprise means for a manual input.

21. The system of claim 13, wherein first monitoring means comprise means for the automatic recognition of a peripheral device allocated to the patient.

22. The system of claim 13, wherein the first monitoring means and/or the acknowledgement means comprise display means for displaying the allocation of peripheral device and treatment unit.

23. The system of claim 13, wherein the control signal sending means, the patient signal sending means, the control signal receiving means, and the patient signal receiving means comprise wireless transmission of the signals.

24. The system of claim 13, wherein the treatment unit is a blood treatment apparatus with an extracorporeal blood circuit.
