Abstract

A medical system for monitoring a measured value of a patient characterizing blood clotting and/or for setting a medication that influences blood clotting for a patient in a home environment, has a device for acquiring measured values of the patient relating to blood clotting, a device for transmitting the measured values to a system central, a device for interrogating the measured values, and a reception device at a monitoring person. The system central has a memory for the measured values, an analysis device for the measured values by comparing the measured values to stored reference values, an alarm generator which generates an alarm signal upon a recognition of predetermined conditions, and a routing device for forwarding the alarm signal to a reception device of a person to be alerted in a process chain.

Claims

1. A medical system for monitoring a measured value of a patient in a home environment, characterizing blood clotting of said patient, comprising:

a measured value acquisition device adapted for interaction with a patient to acquire measured values relating to blood clotting of said patient;

a transmission device connected to said measured value acquisition device for transmitting said measured values to a system central;

said system central having a memory at which reference values are stored, and an analysis device, supplied with said measured values and having access to said memory, for comparing the measured values to said reference values and which identifies a level of urgency, from among a plurality of different levels of urgency, for any treatment needed by the patient dependent on a relationship of said measured values to said reference values, and an alarm generator which generates at least one alarm signal from among a plurality of different alarm signals respectively allocated to said different levels of urgency;

a plurality of reception devices located remote from said system central, and respectively associated with different persons, respectively adapted o respond to said different levels of urgency, in a response chain; and

said system central further including a routing device supplied with said alarm signal, and said routing device routing said alarm signal to at least one of said reception devices to notify at least one person in said response chain adapted to the level of urgency identified by said analysis device, said routing system automatically differently routing said alarm signal, dependent on the level of urgency, to respectively different persons in said response chain.

2. A medical system as claimed in claim 1 wherein said memory at said system central contains stored reference value limits associated with said reference values, and wherein said alarm generator generates said alarm signal given upward or downward transgression of said stored reference value limits by said measured values, and wherein said routing device routes said alarm signal to a reception device, among said plurality of reception devices, associated with a person responsible for treatment of said patient.

3. A medical system as claimed in claim 1 wherein said memory at said system central contains stored reference value limits, associated with said reference values, and wherein said alarm generator generates said alarm signal given significant upward or downward transgression of said reference value limits by said measured values, and wherein said routing device routes said alarm signal to a reception device, among said plurality of reception devices, associated with an emergency response person.

4. A medical system as claimed in claim 1 wherein said alarm generator generates said alarm signal given failure of said measured values to arrive at said system central, and wherein said routing device routes said alarm signal to a reception device, among said plurality of reception devices, associated with said patient.

5. A medical system as claimed in claim 1 wherein said analysis unit generates an analysis result dependent on the comparison of said measured values to said reference values, and wherein said routing unit routes said analysis result to a reception device, among said plurality of reception devices, associated with a person responsible for treatment of said patient, and wherein said alarm generator generates said alarm signal given a lack of reaction of said person responsible for treatment of said patient, and wherein said routing unit routes said alarm signal to a further reception device, among said plurality of reception devices, associated with an Emergency Response person.

6. A medical system as claimed in claim 1 wherein said alarm generator generates said alarm signal with routing information contained therein, and wherein said routing device routes said alarm signal to one of said plurality of reception devices designated by said routing information.

7. A medical system as claimed in claim 1 wherein said routing device automatically routes said alarm signal to one of said reception devices defined by said routing device dependent on availability.

8. A medical system as claimed in claim 1 wherein said routing device is a learning expert system.

9. A medical system as claimed in claim 1 wherein said analysis device comprises a learning expert system that interprets said measured values in a pathology specific manner using an analysis basis selected from the group consisting of rule systems and probabilities.

10. A medical system as claimed in claim 1 wherein said analysis device comprises a learning expert system that interprets said measured values in a problem specific manner using an analysis basis selected from the group consisting of rule systems and probabilities.

11. A medical system as claimed in claim 1 wherein said analysis device comprises a learning expert system that interprets said measured values in a pathology specific and a problem specific manner using an analysis basis selected from the group consisting of rule systems and probabilities.
