1. A medical device for drug administration comprising:
- a) a device which measures at least one body parameter of a patient for at least one measuring cycle and at least one monitoring cycle,b) a central control unit programmed to generate a normalized curve for each of the at least one measured body parameter of the patient from measured data obtained in the at least one measuring cycle and to adjust the measured data obtained in the at least one monitoring cycle to normalize the measured data based on the normalized curve to generate normalized monitoring data, andc) an ingestible capsule which starts releasing the drug in response to a change of at least 25%/hour on a normalized scale being observed in the normalized monitoring data for a period of at least 1 hour.

10. A method for the controlled release of drugs from a capsule, comprising:
-
a) measuring at least one body parameter of a patient for at least 3 measuring cycles and at least one monitoring cycle, b) generating a normalized curve for the measured body parameter of the patient; c) adjusting the measured body parameter obtained in the at least one monitoring cycle to normalize the measured body parameter based on the normalized curve to generate normalized monitoring data, and d) starting to release a drug during the at least one monitoring cycle in response to at least observing a change of at least 25% in the normalized measured body parameter for a period of one hour. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A drug administration device comprising:
-
an ingestible capsule; a parameter monitor disposed in the ingestible capsule to measure at least one body parameter of a patient who has ingested the ingestible capsule; a drug storage container disposed in the ingestible capsule which stores drugs; a valve which is controllable to release the drugs in the drug storage container from the ingestible capsule; and a control unit disposed in the ingestible capsule, the control unit receiving measured body parameter data from the parameter monitor, generating a normalized curve from the measured body parameter data over a plurality of monitoring cycles, normalizing the measured body parameter data, and controlling the valve to release the drugs in response at least to the normalized measured body parameter changing at a preselected rate for a preselected duration. - View Dependent Claims (19)
