Abstract

In a method for recording and evaluating measurements related to the condition of a patient for configuration of a portable, patient-controlled device operated to record the measurements,—at least one measurement describing the condition of the patient is recorded by the device,—the measurement and/or at least one parameter derived therefrom is/are transferred to an evaluation device via a communication connection,—the measurement and/or the parameter is/are evaluated by or on the evaluation device by an expert system and/or an expert to determine patient-specific information,—configuration data ascertained in consideration of the patient-specific information is transferred back to the device via the or another communication connection, and—the device is configured according to the configuration data.

Claims

1. A method for recording and evaluating measured values relating to the condition of a patient for the purpose of configuring a portable appliance which is used by the patient and which is operated for the purpose of recording the measured values, the method comprising:

recording at least one measured value describing the condition of the patient using the appliance,

transmitting at least one of the measured value and at least one variable derived therefrom to an evaluation device via a communication link,

evaluating at least one of the measured value and the variable by the or on the evaluation device in order for at least one of an expert system and an expert to ascertain patient-specific information,

transmitting configuration data ascertained taking account of the patient-specific information back to the appliance via the or a further communication link, and

configuring the appliance in accordance with the configuration data,

wherein an appliance which is designed to output at least one of patient information and warnings on the basis of at least one action criterion which evaluates the measured value or on the basis of at least one threshold value, is used, wherein the appliance is provided with updated action criteria or updated threshold values ascertained as part of the measured value evaluation on the evaluation device, by the configuration data.

2. The method according to claim 1, wherein the appliance used is an appliance which records a measured value relating to the lung.

3. The method according to claim 2, wherein the measured value measured is an NO value, in particular end-expiratory.

4. The method according to claim 1, wherein the appliance used is a handheld device or a mobile telephone or a handheld device or mobile telephone with at least one of a supplementary apparatus and an attachment for measuring.

5. The method according to claim 1, wherein measured values recorded at different times are stored and are transmitted and evaluated as a measured value profile curve.

6. The method according to claim 5, wherein the measured value profile curve is evaluated as part of automatic preliminary evaluation for values characterizing the profile which are then taken into account for the evaluation on the evaluation device.

7. The method according to claim 6, wherein the preliminary evaluation is performed by at least one of the appliance itself by an interposed apparatus or at least one of a base unit, and by the evaluation device.

8. The method according to claim 6, wherein values characterizing the profile which are ascertained are at least one of local maxima, local minima, the gradient, and a drift behavior.

9. The method according to claim 6, wherein the preliminary evaluation also involves at least one of the first and second time derivative of the profile curve being ascertained and taken into account.

10. The method according to claim 1, wherein the evaluation involves further patient-specific data being taken into account.

11. The method according to claim 1, wherein the communication link used is at least one of a WLAN connection, a Bluetooth link, a mobile radio link, and a GPRS connection.

12. The method according to claim 1, wherein the measured value is accompanied by the transmission of an explicit identification number for at least one of the appliance, for a component of the appliance, and for a base station explicitly associated with the appliance.

13. The method according to claim 1, wherein if at least one of the measured values and the evaluation result satisfy at least one criterion for a possibly critical situation then at least one of the measured values and the evaluation result is forwarded to a doctor.

14. The method according to claim 1, wherein the patient-specific information is taken as a basis for configuring the appliance for the purpose of at least one of outputting a text message and for sending the patient an SMS with a text message, which text message.

15. The method according to claim 1, wherein a plurality of measured values recorded at different times are subjected to automatic plausibility evaluation.

16. The method according to claim 15, wherein if nonplausibility is identified, at least one of an appliance malfunction and an appliance fault is assumed and at least one of the patient and a third person is automatically notified thereof by means of at least one of a report on the appliance, and an SMS, and an e-mail.

18. The method according to claim 10, wherein the further patient-specific data is at least one of the age, the weight, the sex, the medical history, external regional factors, the weather, and pollen counts.

19. The method according to claim 12, wherein the explicit identification number the MAC number of a network card in the appliance or the base station, which identification number is used in order for the evaluation device to at least one of:

identify the patient associated with the measured values and in order to ascertain the sending destination when returning.

20. The method according to claim 14, wherein the text message comprises an updated critical threshold value for the measured value.

17. An apparatus for the assisted self-examination of a patient, comprising a portable assisted self-examination of a patient, comprising a portable appliance which is used by the patient and which is operated for the purpose of recording at least one measured value relating to the condition of a patient, which appliance is connected or can be connected to an evaluation device via a bidirectional communication link, and the evaluation device, designed to

record at least one measured value describing the condition of the patient using the appliance,

transmit at least one of the measured value and at least one variable derived therefrom to an evaluation device via a communication link,

evaluate at least one of the measured value and the variable by the or on the evaluation device in order for at least one of an expert system and an expert to ascertain patient-specific information,

transmit configuration data ascertained taking account of the patient-specific information back to the appliance via the or a further communication link, and

configure the appliance in accordance with the configuration data,

wherein an appliance which is designed to output at least one of patient information and warnings on the basis of at least one action criterion which evaluates the measured value or on the basis of at least one threshold value, is used, wherein the appliance is provided with updated action criteria or updated threshold values ascertained as part of the measured value evaluation on the evaluation device, by the configuration data.
