Abstract

In a tele-evaluation system, especially a tele-medicine system for centralized remote evaluation of information, particularly medical patient information and measurement data, based on one-time use articles (disposable items) that are identified with data and/or can collect measurement data, the disposable items carries an individual encoding key for encoding the data in a patient station that is linked via data line or data network to a storage station and/or evaluation-reception station. A disposable-ID is applied to or stored in the disposable item and is automatically collected at the patient station and is simultaneously transmitted unencoded, with an identifier for the patient station. The reception station has a data link to the disposable item manufacturer in order to query, using the disposable-ID, the individual key for decoding the data.

Claims

1. A tele-evaluation system for centralized remote evaluation of medical patient information and medical measurement data comprising:

a plurality of one-time usable;

disposable items associated with a medical procedure having data associated therewith;

each disposable item having a unique disposable identifier associated therewith and each disposable item also carrying a unique encoding key for encoding said data associated with the medical procedure for which the disposable item is employed;

a patient station and an evaluation station located remote from said patient station, said patient station and said evaluation station being in data communication via a data link selected from the group consisting of a data line and a data network;

said patient station having a data interface via which said data associated with said medical procedure are entered into said patient station in encoded form, according to said encoding key carried by the disposable item employed in the medical procedure;

said patient station transmitting, to said evaluation station said data in encoded form, and said disposable identifier with no encoding, together with an identifier for a patient who participated in the medical procedure, and said evaluation station being connected via a data link to a manufacturer of said disposable item to transmit said disposable identifier to said manufacturer to obtain, in return, said encoding key, via said disposable identifier, for decoding said data; and

said evaluation station evaluating said data to produce diagnostic information and transmitting said diagnostic information back to said patient station via said data link.

2. A tele-evaluation system as claimed in claim 1 wherein said disposable identifier is represented by readable information applied to said disposable item.

3. A tele-evaluation system as claimed in claim 1 wherein said disposable identifier is electronically stored in a chip in said disposable item.

4. A tele-evaluation system as claimed in claim 1 wherein said evaluation station transmits diagnostic information via said data link back to said patient station after evaluating said data associated with said medical procedure.

5. A tele-evaluation system as claimed in claim 1 wherein said data link between said evaluation station and said manufacturer is a secure data line.

6. A tele-evaluation system as claimed in claim 1 wherein, upon transmittal of said disposable identifier from said reception station to said manufacturer, said manufacturer, in addition to said encoding key, transmits information selected from the group consisting of calibration factors for a measurement device employing said disposable item, efficacy factors related to a measurement device employing said disposable item, and information relating to medicine for said medical procedure back to said evaluation station.

7. A tele-evaluation system as claimed in claim 1 further comprising a central patient data bank having a communication link to said evaluation station.

8. A tele-evaluation system as claimed in claim 1 wherein said evaluation station has access to an expert system for evaluating said data.

9. A tele-evaluation system as claimed in claim 1 further comprising an accounting computer, having a communication link with said evaluation station which individually calculates a fee for a service associated with use of said disposable item identified by said disposable identifier.

10. A tele-evaluation system as claimed in claim 1 wherein said evaluation station includes means for blocking receipt, from said patient station, of a disposable identifier that has been previously received at said evaluation station.

11. A tele-evaluation system as claimed in claim 1 wherein said evaluation station, in addition to said diagnostic information, transmits back to said patient station information relating to said medical procedure selected from the group consisting of success rates, compatibility information and side effects, and also anonymously transmits information to said manufacturer via said data link regarding usage of said disposable item.

12. A method for tele-evaluation of medical information comprising the steps of:

providing a plurality of one-time usable, disposable items respectively for use in medical procedures having data associated therewith;

uniquely identifying each of said disposable items with a disposable identifier and permanently associating each disposable item with an individual encoding key;

at patient station, entering said data associated with said medical procedure together with information about a patient who participated in the medical procedure, together with said disposable item identifier and said encoding key;

establishing a communication link between said patient station and an evaluation station remote from said patient station;

via said communication link, transmitting said data associated with said medical procedure, said patient information and said disposable identifier to said evaluation station with at least said data associated with the medical procedure being encoded using said encoding key, and with said disposable identifier being transmitted unencoded;

upon receipt of the encoded data associated with the medical procedure, and the disposable ID, at the evaluation station, said evaluation station establishing a further communication link with a manufacturer of said disposable item;

via said further communication link, said evaluation station transmitting said disposable identifier to said manufacturer and in return obtaining said encoding key from said manufacturer, and, at said evaluation station, decoding said data associated with said medical procedure to obtain decoded data; and

at said evaluation station, evaluating said decoded data to obtain diagnostic information and transmitting said diagnostic information back to said patient station via said communication link.
