Metabolic monitoring, a method and apparatus for indicating a health-related condition of a subject

摘要

An apparatus for indicating a health-related condition of a subject has an input interface for receiving a sequence of samples of a first biological quantity derived by a first measurement method, the first measurement method being an invasive measurement and having a first impact on the subject, and for receiving a sequence of samples of a second biological quantity derived by a second measurement method, the second measurement method being a non-invasive measurement and having a second impact on the subject, wherein the first biological quantity gives a more accurate indication of the health-related condition of the subject than the second biological quantity, wherein the first biological quantity and the second biological quantity have a correlation to the health-related condition of the subject, and wherein the second impact is smaller than the first impact; a predictor for providing, for a certain time, for which no sample for the first biological quantity exists, an estimated value of the first biological quantity using samples for the first biological quantity and, as far as available, samples for the second quantity; and an output interface for outputting the estimated value or data derived from the estimated value so that an indication for the health-related condition of the subject is obtained.

主权项

1. An apparatus for indicating a health-related condition of a subject, comprising:
an input interface for receiving a raw sequence of samples of a biological quantity derived by a measurement method and a further raw sequence of a different biological quantity derived by a further measurement method; a first processor for processing the raw sequence of samples to obtain a processed sequence, the first processor comprising an interpolator for providing data on an interpolated sample for a missing sample of the biological quantity using one or more samples at a preceding time instant or one or more samples at a subsequent time instant to obtain an interpolated sequence representing samples of the raw sequence and the interpolated sample; a filter for filtering the processed sequence provided by the first processor to obtain a filtered sequence, the filtered sequence having a useful variation and a reduced non-useful variation compared to the processed sequence before filtering, wherein the filter is configured for filtering the further raw sequence to obtain a further filtered sequence; an output interface for processing an enhanced sequence derived from the filtered sequence and for outputting at least an increase indication, a decrease indication or a remain unchanged indication as a trend of the enhanced sequence, the trend being representative of a useful variation of the health-related condition of the subject; and a second processor for deriving the enhanced sequence from the filtered sequence, wherein the second processor comprises a combiner, for combining the filtered sequence and the further filtered sequence to derive the enhanced sequence.
