Abstract

Monitoring equipment including means for receiving a measurement result indicating the patient'"'"'s blood glucose level, and for staring it in a first memory means. In order to improve and facilitate the treatment of the patient, the monitoring equipment further includes means for receiving data concerning the patient'"'"'s diet, medication and physical strain, and for storing it in the first memory means, data processing means for calculating a predictive value on the basis of the data stored in the first memory means, and corrector means for calculating the difference between the calculated predictive value and the patient'"'"'s actual blood glucose level, and for correcting the mathematical model utilized to calculate the predictive value in order to take into account the aforementioned difference in subsequent calculations of predictive values.

Claims

1. A method for predicting the glucose level in a patient'"'"'s bloods, the method comprising the steps of:

formulating an adaptive mathematical model about the behavior of the patient'"'"'s blood glucose level, the model taking into account at least the patient'"'"'s diet, medication and physical strain and providing predictive values;

providing the patient with means for utilizing said mathematical model, so that the patient can himself monitor and predict the effect of the treatment he is to follow on the behavior of his blood glucose level; and

comparing the predictive values provided by the model to measured glucose levels and correcting the mathematical model on the basis of the result of said comparison.

2. A monitoring equipment for predicting the glucose level in a patient'"'"'s blood, the equipment comprising:

means for receiving a measurement result indicating the glucose level in a sample of the patient'"'"'s blood and for storing the measurement result in a first memory means together with data indicating the moment of the measurement,

means for receiving data concerning at least the patient'"'"'s diet, medication and physical strain and for storing the received data in the first memory means,

data processing means for calculating a predictive value using a mathematical model taking into account the data stored in the first memory means, the predictive value indicating the patient'"'"'s predicted blood glucose level at a predetermined moment, and

corrector means for calculating the difference between the calculated predictive value and the patient'"'"'s actual blood glucose level measured at said predetermined moment, and for correcting the mathematical model utilized by the data processing means to calculate a predictive value in order to take into account said difference in subsequent calculations of predictive values.

3. Monitoring equipment according to claim 2, wherein the data processing means comprises:

second memory means for storing correction coefficients utilized in the calculation of the predictive value, and

means for searching from the second memory means, the correction coefficients corresponding to the data stored in the first memory means, and to utilize said correction coefficients in the calculation of the predictive value,

the corrector means being arranged to change the value of the correction coefficients used in the calculation in order to minimize the difference between the predictive value and the glucose level measured at said predetermined moment, and to store said changed correction coefficients in the second memory means.

4. Monitoring equipment according to claim 2, wherein said means for receiving data, said data processing means, and said corrector means are included in a data processing system of a hospital or a health care center, wherein the equipment further comprises a communications device that is available to the patient and that utilizes a wireless data transmission link, wherein the means for receiving data concerning the measurement result, moment of measurement, diet, medication and physical strain comprises means for receiving said data from said communications device, and wherein the monitoring equipment comprises transmitter means for transmitting the calculated predictive value to the communications device available to the patient.

5. Monitoring equipment according to claim 2, further comprising a measuring unit for measuring the glucose level of a patient'"'"'s blood sample, and for storing the data indicating the measurement result and the moment of measurement in the first memory means.

6. Monitoring equipment according to claim 5 and comprising a communications device connected to the measuring unit, the communications device comprising a mobile phone of a cellular radio system or to a two-way pager, the monitoring equipment further comprising means for transmitting the data stored in the first memory means via said communications device to a data processing system that is available to a person treating the patient, wherein the measuring unit and a battery of the mobile phone or two-way pager are integrated into one component that fits into a battery space of the mobile phone or two-way pager.

7. Monitoring equipment according to claim 2, further comprising a measuring unit for measuring the glucose level of a patient'"'"'s blood sample, and for storing the data indicating the measurement result and the moment of measurement in the first memory means, and a communications device connected to the measuring unit, the communications device including a mobile phone of a cellular radio system or a two-way pager, and means for transmitting the data stored in the first memory means via said communications device to a data processing system that is available to a person treating the patient.
