## Abstract

The invention relates to a system for the early detection of life-threatening conditions of persons, wherein such risks exist, for example, due to a preceding operation. The system detects a plurality of vital parameters depending on the person to be monitored by means of a detector unit that is subsequently evaluated by an evaluation logic using a neuronal network. Individual parameters that exceed thresholds and constellations of parameters that represent a critical health condition of the person are displayed in different forms by means of a display device, depending on the risk. Said risk is determined in that the probability of the presence of a health anomaly is first determined and then evaluated.

## Claims

### Claim 1

A system that detects the probability of post-operative bleeding in a person, comprising:
a detector unit that records a plurality of vital parameters, wherein the detector unit comprises at least one measuring sensor, an electronic control unit assisted by a computing unit, and an interface, wherein the said detector unit records blood pressure, heart rate of the person and one or more vital parameters of the person selected from the group consisting of:
(a) oxygen content of blood, and
(b) tissue pressure;
wherein said electronic control unit executes an evaluation logic embodied in a computer-readable medium and assigns a predefined condition to each vital parameter measured by the at least one measuring sensor, and assesses a probability of post-operative bleeding as a function of the assigned predefined conditions, wherein the evaluation logic generates, based on medical history of the person, the recorded parameters, and the assigned conditions, taking into consideration their variation in time, an instruction on how to deal with the predicted post-operative bleeding and equipment necessary to deal with the predicted post-operative bleeding; and
a display device which receives from the detector unit via the interface the probability of post-operative bleeding from the computing unit and displays the probability of post- operative bleeding and the instruction.

### Claim 2 (depends on 1)

The system of claim 1, wherein the evaluation logic comprises a neuronal network.

### Claim 3 (depends on 1)

The system of claim 1, wherein the detector unit records at least one of the vital parameters at a predefined time interval.

### Claim 4 (depends on 1)

The system of claim 1, wherein the evaluation logic comprises a fuzzy logic algorithm.

### Claim 5 (depends on 2)

The system of claim 2, wherein the neuronal network is trainable by incorporating individual medical data of the person.

### Claim 6 (depends on 4)

The system of claim 4, wherein the fuzzy logic algorithm of the evaluation logic is individually calibrated in a manner corresponding to the health of the person.

### Claim 7 (depends on 1)

The system of claim 1, wherein the evaluation logic is capable of learning.

### Claim 8 (depends on 1)

The system of claim 1, wherein various levels of a health danger can be displayed by the display device.

### Claim 9 (depends on 1)

The system of claim 1, further comprising a transmitter unit, which communicates to a control center at least one selected result of the assessment of a probability of post-operative bleeding or an instruction on how to deal with a momentary condition of the person.

### Claim 10 (depends on 9)

The system of claim 9, further comprising a position detector, which identifies a spatial or geographic position of the person.

### Claim 11 (depends on 10)

The system of claim 10, wherein the spatial or geographic position of the person is communicated by the transmitter unit to a control room.

### Claim 12 (depends on 1)

The system of claim 1, wherein said interface is an interface to a mobile telephone.

### Claim 13 (depends on 1)

The system of claim 1, wherein all elements of the system are combined in one unit.

### Claim 14 (depends on 1)

The system of claim 1, wherein the person has undergone a tonsillectomy surgery or a thyroid surgery.

### Claim 15 (depends on 1)

The system of claim 1, wherein said detector unit records the blood pressure, heart rate, and tissue pressure of the person.

### Claim 16 (depends on 1)

The system of claim 1, wherein said detector unit records the blood pressure, heart rate, and oxygen content of the blood of the person.

### Claim 17 (depends on 1)

The system of claim 1, wherein said detector unit records the blood pressure, heart rate, tissue pressure, and oxygen content of the blood of the person.
