Abstract

A surgical or medical container content detection system includes a container content sensor device for arrangement in a sterilization container. The container content sensor device includes a carrier and at least one sensor arranged or formed on the carrier for detecting at least one identification element which is arranged or formed on an object stored in the sterilization container for the identification thereof. A carrier module arranged on the carrier includes a detection device for detecting at least one detected identification element and is arranged for the purpose of wirelessly transmitting information about the object identified by the detected identification element to the outside of the sterilization container.

Claims

1. A medical container content detection system, comprising:

a container content sensor device for arrangement in a sterilization container, which container content sensor device comprises a carrier and at least one sensor arranged or formed on the carrier for detecting at least one identification element which is arranged or formed on at least one object stored in the sterilization container for the identification thereof;

a carrier module arranged on the carrier, wherein the carrier module includes a detection device for detecting the at least one identification element and an energy supply unit for supplying the container content sensor device with energy, arranged for the purpose of wirelessly transmitting information about the at least one object identified by the at least one identification element by radio-based data transmission to an outside of the sterilization container and is combined to form a steam-pressure sterilizable unit; and

a screen basket comprising at least one storing means for storing the at least one object, said screen basket being adapted to be introduced to the sterilization container,

wherein the container content sensor device is arranged or retained in the screen basket.

2. The medical container content detection system according to claim 1, wherein the container content sensor device includes at least one data transmission device and a wireless interface for transmitting and/or extracting detection signals generated by the at least one sensor to a read-out and/or evaluating unit external to the container for determining the at least one object stored in the sterilization container in response to detection signals generated by the at least one sensor.

3. The medical container content detection system according to claim 1, wherein the at least one sensor forms a transponder reading device and/or a wirelessly operating data transmission device for transmitting detected data and/or detection signals to a read-out and/or evaluating unit external to the container, and the carrier module is cast to form the steam-pressure sterilizable unit and/or is combined by enclosing.

4. The medical container content detection system according to claim 3, wherein the energy supply unit is arranged for energy self-supply of the container content sensor device and comprises at least one rechargeable energy storing unit which can be supplied with electrical energy generated inductively or by means of thermal generation on the container side.

5. The medical container content detection system according to claim 1, wherein the carrier module includes a storage unit for storing fixed data and at least intermediately storing detected data, wherein the storage unit is arranged for permanently storing at least identification information of the sterilization container including at least a serial number or an identification of the same, and/or for intermediately storing at least data generated by a temperature, humidity and/or pressure level detection device in relation to a temperature, humidity and/or pressure level curve at the sterilization container, said data containing at least information about a recent sterilization period or a number of sterilization cycles, data detected by the at least one sensor relating to the identification elements or data relating to a sterilization history and/or a maintenance history of the sterilization container.

6. The medical container content detection system according to claim 1, wherein the carrier module includes a relay function which is configured for activating and/or deactivating at least parts of the container content sensor system including the carrier module itself, wherein the relay function can be self-triggered in response to changes of condition detected on the carrier module or can be remote-triggered dependent on or independent of said changes of conditions.

7. The medical container content detection system according to claim 1, wherein the at least one sensor is arranged for detecting the at least one identification element in the form of a transponder.

8. The medical container content detection system according to claim 1, wherein the at least one sensor is in the form of a transponder and is received in a recess of the carrier.

9. The medical container content detection system according to claim 1, wherein the carrier surrounds the carrier module and the at least one sensor at least partially by form closure and is made from steam-pressure sterilizable material.

10. The surgical container content detection system according to claim 1, wherein the carrier is made from glass or plastic material.

11. The medical container content detection system according to claim 1, wherein the carrier is in the form of a mat.

12. The medical container content detection system according to claim 1, wherein the carrier is in the form of an insertion pattern on which objects to be stored in the sterilization container are shown at least schematically.

13. The medical container content detection system according to claim 1, further comprising a sterilization container comprising a lower container part and an upper container part for closing the lower container part, wherein the container content sensor device can be inserted in the sterilization container free from mechanical connections.

14. The medical container content detection system according to claim 1, wherein the screen basket or a section of the screen basket forms an antenna or can be used as an antenna.

15. A medical container content detection system, comprising:

a container content sensor device for arrangement in a sterilization container, which container content sensor device comprises a carrier and at least one sensor arranged or formed on the carrier for detecting at least one identification element which is arranged or formed on at least one object stored in the sterilization container for the identification thereof; and

a carrier module arranged on the carrier, wherein the carrier module includes a detection device for detecting the at least one identification element and an energy supply unit for supplying the container content sensor device with energy, arranged for the purpose of wirelessly transmitting information about the at least one object identified by the at least one identification element by radio-based data transmission to an outside of the sterilization container and is combined to form a steam-pressure sterilizable unit,

wherein the carrier module is arranged for providing a device for sterilization container tracking and/or positioning based on a Received Signal Strength Indicator value and/or a direction identification device in connection with a high-accuracy indoor positioning and Bluetooth Low Energy conformity in relation to the energy self-supply of the container content sensor device.

16. A medical container content detection system, comprising:

a container content sensor device for arrangement in a sterilization container, which container content sensor device comprises a carrier and at least one sensor arranged or formed on the carrier for detecting at least one identification element which is arranged or formed on at least one object stored in the sterilization container for the identification thereof;

a screen basket including at least one storage unit for the at least one object, which screen basket can be introduced to the sterilization container; and

a carrier module arranged on the carrier which has a detection means for detecting at least one detected identification element and is arranged for the purpose of wirelessly transmitting information about the at least one object identified by the detected identification element to the outside of the sterilization container,

wherein the screen basket or a section of the screen basket forms an antenna or can be used as an antenna.
