Embodiment Construction

[0060] The illustrations in the figures are schematic.

[0061]figure 1 A simplified block diagram 100 of a drug delivery system is shown. The drug delivery system 100 comprises a measurement device 110 comprising a temperature sensor 114 and a sensor 120 for detecting the posture and / or acceleration of at least a part of the patient's body. Sensors 112 and 114 are coupled to control unit 120 by means of data connection 113 . The control unit is realized by means of a microcontroller 120 .

[0062] The control unit 120 is also connected to the drug delivery device 150 by means of a wired or wireless data connection 122 , which allows controlling the drug delivery device 150 based on the measurement signal provided by the measurement device 110 . These signals indicate the current activity status of the patient.

[0063] The drug delivery system 100 also includes a transmitter unit 130 coupled to the control unit 120 . The transmitter unit 130 and the control unit 120 may b...

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.

Description

technical field [0001] The present invention relates to the field of drug delivery to patients. In particular, the present invention relates to a system and method for automatically delivering drugs in correct doses to a patient's body by appropriately controlling the operation of a drug delivery device. Background technique [0002] Medicines have traditionally been delivered via tablets or capsules for oral administration. These drug administrations are performed once a day, for example, in the morning or evening. This results in an accumulation of drug in blood drug levels following ingestion and a subsequent exponential decay of the drug in the blood over time. Many advanced systems take into account the timing of drug therapy to increase drug efficacy by advising the patient to take the drug preferably at a certain time of day, such as in the evening after dinner. At some time during the day before the next dose, blood drug levels may be below the lower therapeutic l...
