Abstract

The invention comprises a single-use, self-contained measuring device, comprising a data entry- and sampling part including a sensor for measuring of physical or chemical property of a foreign substance and a data acquisition part including electronic processing- and storage means, where the parts are integral parts of a packaging, formed of a sheet-like, printable and foldable material, the packaging being designed to enclose and protect the parts contained therein. The packaging may also include various instruments needed to perform a test.

Claims

1. A single use, self-contained measuring device comprising:

a data entry- and sampling part including a sensor for measuring a property of a foreign substance and a data acquisition part including electronic processing and storage means, wherein the data entry- and sampling part and the data acquisition part are integral parts of a packaging, formed of a sheet-like, printable and foldable material, the packaging being arranged to enclose and protect parts contained therein.

2. A device in accordance with claim 1, wherein the foldable material comprises a laminate comprising a bottom sheet and a top sheet, an electronic module applied on a flexible film is fixed and conductive traces are printed on the bottom sheet and the bottom sheet and the top sheet are bonded together on top of each other by an electrically conductive adhesive layer.

3. A device in accordance with claim 1, wherein the sensor is printed on the bottom sheet and connected to conductive traces connected to the electronic module.

4. A device in accordance with claim 1, wherein the sensor is attached to the bottom sheet by an electrically conductive adhesive layer.

5. A device in accordance with claim 3 wherein the device comprises a plurality of sensors to allow several acquisitions to be performed at more than one single event or several measurements to be performed on a single acquisition.

6. A device in accordance with claim 4 wherein the device comprises a plurality of sensors to allow several acquisitions to be performed at more than one single event or several measurements to be performed on a single acquisition.

7. A device in accordance with claim 2 wherein the bottom and top sheets are covered with moisture barrier layers.

8. A device in accordance with claim 1 wherein the data acquisition part is detachable from the data entry- and sampling part.

9. A device in accordance with claim 8 wherein each detachable part is uniquely marked to allow parts from different devices to be identified after having been detached.

10. A device in accordance with claim 1, wherein the packaging may contain an additional item needed for performing the measuring.

11. A device in accordance with claim 1 wherein the data acquisition part comprises an electronic module comprising an electronic chip, a power source and data communication means for exchanging data, the chip having data acquisition means, data processing means, a non-volatile data storage means and time-keeping means, the time-keeping means being used to attach a time-stamp to generated data stored in the data storage means.

12. A device in accordance with claim 11 wherein the electronic module comprises connection points connected to corresponding printed connector means for connecting the electronic module to printed conductive traces connected to the sensor on the data entry- and sampling part.

13. A device in accordance with claim 11 wherein the electronic chip have a temperature measuring means in order to quantify the temperature in proximity to the sensor.

14. A device in accordance with claim 12 wherein the electronic chip comprises a temperature measuring means in order to quantify the temperature in proximity to the sensor.

15. A device in accordance with claim 12 wherein the temperature measuring means provide a quantified value of the ambient temperature value at the time the acquisition is taking place and said temperature value is being used as an operator in converting temperature dependency of a result of the measuring.

16. A device in accordance with claim 13 wherein the temperature measuring means is used to monitor if permissible temperature limits of the device has been exceeded in the lifecycle of the device from production to a point when the acquisition is completed.

17. A device in accordance with claim 15 wherein the temperature measuring means is used to monitor if permissible temperature limits of the device has been exceeded in the lifecycle of the device from production to a point when the acquisition is completed.

18. A device in accordance with claim 11, wherein the time-keeping means is initialized from a centralized time source and the time-keeping means is maintained by the power source up to the point when the acquisition has been completed and is thereafter switched off to conserve power.

19. A device in accordance with claim 11, wherein the electronic module comprises an audible means or optically visible means to interact with the user of the device.

20. A device in accordance with claim 19, wherein said optically visible means are shapes printed on the bottom sheet surface using electro-chrome ink.

21. A device in accordance with claim 11, wherein the device comprises a compartment containing a desiccant to remove moisture and improve reliability of the measuring by the sensor.

22. A device in accordance with claim 1, wherein the data communication means is used to exchange data between the data processing means and an external host computer for receiving data.

23. A device in accordance with claim 1, wherein the packaging comprises an additional part having a questionnaire panel allowing a user of the device to give additional remarks.

24. A device in accordance with claim 1, wherein the acquisition part comprises a card provided with a preprinted address field allowing the part to be mailed or collected after detachment from the data entry- and sampling part, without additional activity of the user of the device.
