Abstract

It is described a drug delivery system (100) that is adapted to infuse at least one drug in a profile related to the status of a patient. The system comprises sensors (110), dedicated electronics (140) and software to monitor the patient'"'"'s activity and maintain control over the drug-release profile. A control unit (120) of the system (100) is adapted to temporarily set at least one component (110, 120, 150) of the system (100) in an idle mode (265). This will result in particular in a reduction of power required by the system (100). The described system (100) enables a personalized treatment of patients by monitoring their individual activity status and coupling this information to a drug delivery following appropriate delivery profiles. The system (100) may be provided with a memory in order to store a time dependence of activity data. This time dependence may be used by physicians to monitor, support and adapt their therapy for the patients. The system (100) may be realized as a closed-loop system for monitoring and treatment of various diseases such as hemophilia A and Parkinson.

Claims

1. A system for delivering at least one drug to the body of a patient, the system (100) comprising

a measurement device (110) for measuring at least one measurement value, which is indicative for the status of the patient,

a control unit (120), which is coupled to the measurement device (110) and which is adapted to determine a control signal based on the measurement value, and

a drug delivery device (150), which is coupled to the control unit (120) and which is adapted to deliver the drug to the patient'"'"'s body based on the control signal, wherein

the control unit (120) is adapted to temporarily set at least one component (110, 120, 150) of the system (100) in an idle mode (265).

2. The system according to claim 1, wherein

the control unit (120) is adapted to control a sampling rate of the measurement device (110).

3. The system according to claim 1, wherein

the measurement device (110) comprises an acceleration sensor (112), in particular a three-dimensional acceleration sensor.

4. The system according to claim 1, wherein

the measurement device (110) comprises a magnetic field sensor.

5. The system according to claim 1, wherein

the measurement device (110) comprises a temperature sensor (114).

6. The system according to claim 1, wherein

the measurement device (110) comprises a skin impedance sensor.

7. The system according to claim 1, further comprising

a memory for storing a plurality of measurement values, which are indicative for the status of the patient, wherein the measurement values have been acquired at different times.

8. The system according to claim 1, wherein

the measurement device (110), the control unit (120) and/or the drug delivery device (150) is implantable into a patient'"'"'s body.

9. The system according to claim 1, wherein

the control unit (120) is adapted to allow for an interventional control ability.

10. The system according to claim 1, further comprising

a radio transmitter (130), which is coupled to the control unit (120).

11. The system according to claim 1, further comprising

a battery monitoring circuit (140), which is adapted to monitor the state of a battery being used for powering the measurement device (110), the control unit (120) and/or the drug delivery device (150).

12. The system according to claim 1, wherein

the drug delivery device (150) is adapted to deliver liquid type of medication.

13. The system according to claim 1, wherein

the drug delivery device (150) is adapted to deliver solid type of medication.

14. A method for delivering at least one drug to the body of a patient by using a system as set forth in claim 1, the method comprising

measuring at least one measurement value, which is indicative for the status of the patient,

determining a control signal based on the measurement value,

delivering the drug to the patient'"'"'s body based on the control signal, and

temporarily setting at least one component (110, 120, 150) of the system (100) in an idle mode (265).
