Abstract

A modular detection system for insertion in a strainer basket for detecting, monitoring and tracing sterile material in a sterilization circuit. The modular detection system includes a strainer basket insert which can be inserted directly in the strainer basket or arranged on a base plate. The system further includes the following individually and optionally electrically coupleable modules: a central electronic unit, a defined or freely selectable number of slots for attaching and/or connecting a predetermined number of retainer systems for retaining sterile material, each retainer system having at least one antenna system for reading a transponder in the sterile material. The system further includes a preferably defined number of conductor tracks to electrically connect the slots and/or retaining systems to one another and/or to the central electronic unit.

Claims (35)

1 . A modular detection system for insertion into a sieve basket for detecting, monitoring and tracing sterile goods, the modular detection system comprising:

a sieve-basket insert that is designed and configured to be inserted into the sieve basket directly or arranged on a base plate; and

a plurality of modules comprising:

a central electronic unit;

a number of retainer systems that are configured for retaining sterile goods and that each include at least one antenna system for reading a transponder of the sterile goods, wherein each of the number of retainer systems comprises at least one antenna connection;

a number of slots that are defined or freely selectable for connecting and/or coupling sterile goods bearings of the number of retainer systems; and

a number of conducting tracks, which are configured to electrically connect the number of slots and/or the number of retainer systems to each other and/or to the central electronic unit, wherein the number of conducting tracks each comprises at least one antenna connection and data connection compatible with the at least one antenna connection of the number of retainer systems,

each of the plurality of modules being configured to be individually coupled.

2 . The modular detection system according to claim 1 further comprising at least one distribution module in the central electronic unit, the at least one distribution module configured to drive at least two retainer systems via the respective antenna system.

3 . The modular detection system according to claim 1 , wherein multiple distribution modules are configured in such a way that they are connected/connectable in a series with the central electronic unit in order to drive the respective distribution modules in series and thus to switch through the at least one respective antenna system in order to read out the sterile goods lying on the at least one respective antenna system.

4 . The modular detection system according to claim 1 , wherein the at least one respective antenna system of the number of retainer systems is configured as an NFC antenna.

5 . The modular detection system according to claim 1 , wherein the number of retainer systems is each configured with a sensor system for detecting and temporarily storing data, wherein the sensor system has at least one sensor, a data processing unit, a temporary memory, and a rechargeable energy storage unit.

6 . The modular detection system according to claim 5 , wherein the central electronic unit is configured for detecting and temporarily storing data and is in communication with the sensor system of the number of retainer systems and/or with the sterile goods held in the number of retainer systems.

7 . The modular detection system according to claim 5 , wherein the data processing unit is adapted to detect and write data to the number of retainer systems and/or to the sterile goods held by the number of retainer systems.

8 . The modular detection system according to claim 1 , wherein the modular detection system is adapted to communicate and exchange data with at least a second detection system.

9 . The modular detection system according to claim 2 , wherein the central electronic unit is configured to read out data and/or information, via the at least one distribution module, the at least one respective antenna system of the number of retainer systems and to transmit the data and/or information to an external unit, which is configured to visually output the data and/or information.

10 . A retainer system configured to be connected to the modular detection system according to claim 1 ,

the retainer system comprising a sensor system for autonomously detecting process steps.

11 . A sieve basket system for monitoring and tracing sterile goods in a sterile goods cycle, the sieve basket system comprising:

a first sieve basket;

a first modular detection system comprising:

a first sieve-basket insert that is designed and configured to be inserted into the first sieve basket directly or arranged on a first base plate; and

a plurality of first modules comprising:

a central electronic unit:

a number of first slots that are defined or freely selectable for connecting and/or coupling a number of first retainer systems that are configured for retaining sterile goods and that each include at least one respective first antenna system for reading a respective transponder of each of the sterile goods; and

a number of first conducting tracks, which are configured to electrically connect the number of first slots and/or the number of first retainer systems to each other and/or to the central electronic unit,

each of the plurality of first modules being configured to be individually coupled;

a second sieve basket;

a second modular detection system comprising:

a second sieve-basket insert that is insertable into the second sieve basket directly or arranged on a second base plate; and

a plurality of second modules comprising:

a number of second slots that are defined or freely selectable for connecting and/or coupling a number of second retainer systems that are configured for retaining sterile goods and that each include at least one respective second antenna system for reading a respective transponder of each of the sterile goods; and

a number of second conducting tracks, which are configured to electrically connect the number of second slots and/or the number of second retainer systems to each other,

each of the plurality of second modules being configured to be individually coupled, wherein the second modular detection system does not have a central electronic unit; and

wherein the central electronic unit of the first modular detection system is designed and configured to be connected to the second modular detection system.
