Abstract

A sensor module (112) for determining a concentration of at least one analyte in a body fluid of a user is disclosed. The sensor module (112) includes at least one sensor element (116) adapted to determine the concentration of the analyte, wherein the sensor element (116) is at least partly implantable into a body tissue of the user; at least one control device (118) connected to the sensor element (116), wherein the control device (118) includes at least one data collection device (122) adapted to collect measurement data acquired by using the sensor element (116). The control device (118) further includes at least one wireless near-field communication device (124) adapted to transmit measurement data. The control device (118) further includes a rechargeable energy storage device (134) and is adapted to transmit at least one demand for recharging the rechargeable energy storage device (134) via the near-field communication device (124).

First claim

What is claimed is:

1. A sensor module for determining a concentration of at least one analyte in a body fluid of a user comprising:
a. at least one sensor element having a limited life and adapted to determine the concentration of the analyte, wherein the sensor element is at least partly implantable into a body tissue of the user;
b. at least one control device connected to the sensor element, wherein the control device comprises at least one data collection device adapted to collect measurement data acquired by using the sensor element,
wherein the control device further comprises at least one wireless near-field communication device adapted to transmit measurement data,
wherein the control device further comprises a rechargeable energy storage device, and wherein the control device is adapted to transmit at least one demand for recharging the rechargeable energy storage device via the near-field communication device; and
wherein the sensor module is a single-use disposable module having a closed housing with the at least one control device and the rechargeable energy storage device disposed within the housing wherein the housing can only be opened in a destructive manner and wherein the rechargeable energy storage device must be recharged at least once to provide electrical energy to the sensor module for the full duration of the limited life of the sensor element.

2. The sensor module according to claim 1 , wherein the control device is adapted to recharge the rechargeable energy storage device with electrical energy provided externally to the sensor module.

3. The sensor module according to claim 1 , wherein the sensor module further comprises at least one emergency power supply, wherein the emergency power supply is adapted to provide an amount of energy to the rechargeable energy storage device in case a regular recharging is momentarily not feasible.

4. A kit for determining a concentration of at least one analyte in a body fluid of a user, the kit comprising:
a plurality of sensor modules according to claim 1 , and at least one further module, wherein the at least one further module is reusable and adapted to receive the at least one demand for recharging the rechargeable energy storage device from each of the plurality of sensor modules.

5. The kit according to claim 4 , wherein the at least one further module is adapted to provide energy to the rechargeable energy storage device.

6. The kit according to claim 5 , wherein the at least one further module is adapted to provide electrical energy to the rechargeable energy storage device in a contactless fashion.

7. The kit according to claim 4 , wherein the at least one further module comprises at least one portable data management device, wherein the portable data management device is adapted to directly or indirectly receive the measurement data and to at least partially display data on at least one display.

8. The kit according to claim 7 , wherein the portable data management device is adapted to bring the demand for recharging the rechargeable energy storage device to a user's attention.

9. The kit according to claim 7 , wherein the portable data management device is adapted to indicate to a user at least one way of recharging the rechargeable energy storage device.

10. The kit according to claim 9 , wherein the portable data management device is adapted to indicate to the user that at least one recharging module has to be brought into at least one recharging position with respect to the sensor module.

11. The kit according to claim 4 , wherein the at least one further module comprises at least one data reader module adapted to receive measurement data transmitted by the sensor module via wireless near-field communication, wherein the data reader module comprises at least one data storage device and is adapted to store the measurement data.

12. The kit according to claim 4 , wherein the at least one further module comprises at least one data transmission module adapted to receive measurement data transmitted by the sensor module via wireless near-field communication, wherein the data transmission module comprises at least one wireless far-field communication device, wherein the wireless far-field communication device is adapted to transmit at least part of the measurement data to an external device via wireless far-field communication.

13. The kit according to claim 4 , wherein the at least one further module comprises at least one alarm module adapted to receive data transmitted by the sensor module via wireless near-field communication, wherein the data transmitted by the sensor module contain one or both of measurement data or alarm instructions.

14. The kit according to claim 4 , wherein the at least one further module comprises at least one dedicated recharging module adapted to recharge the rechargeable energy storage device.

15. A method for determining a concentration of at least one analyte in a body fluid of a user, the method comprising a use of the sensor module according to claim 1 and transmitting at least one demand for recharging the rechargeable energy storage device of the sensor module via the near-field communication device of the sensor module.

16. A method for determining a concentration of at least one analyte in a body fluid of a user, the method comprising a use of the kit according to claim 4 and transmitting at least one demand for recharging the rechargeable energy storage device of the sensor module via the near-field communication device of the sensor module.
