Method for capturing computer-readable codes, reading device and reading system

A method for capturing multiple computer-readable codes, of a medical product or a packaging of a medical product for assisting a user, the method comprising the steps of:

• capturing an image of the medical product or its packaging having the codes by a capturing device;
• extracting at least a first and a second computer-readable code in the captured image;
• interpreting the code data by an interpretation device and retrieving information of at least a product-ID and further product information from the code data;
• determining, based on the retrieved information, whether a predefined set of relevant information for the medical product is included in the information of the captured code and/or a linked database,
• selecting the second code as a relevant code, when the retrieved information of the first code is fully included in the retrieved information of the second code, or selecting the first code and the second code as the relevant code, if each code includes at least one part of the information of the predefined set of relevant information;
• transmitting, based on the result of the determining and on the result of the selecting, a code marker for each code to a displaying device;
• and
• displaying an overlay image with the captured image and, according to the code marker, a marking of the code for adding assisting visual information to the code in order to provide an improved overview of the computer-readable codes to the user.

A reading device for capturing multiple computer-readable codes of a medical product or a packaging of a medical product for assisting a user, the reading device comprising:

• a capturing device configured to capture an image of the medical product or its packaging having the codes and to extract at least a first and a second computer-readable code in the captured image;
• an interpretation device configured to:
• interpret the code data and retrieve information of at least a product-ID and further product information from the code data,
• determine, based on retrieved information, whether a predefined set of relevant information for the medical product is included in the information of the captured code and/or a linked (master data-) database that is stored in a storage unit of the reading device or in a storage unit of a server,
• select the second code as a relevant code, when the information of the code data of the first code is fully included in the information of the code data of the second code;
• or to select the first code and the second code as the relevant code, if each code includes at least one part of the information of the predefined set of relevant information, and
• transmit, based on the result of the determining and on the result of the selecting, a code marker for each code to a displaying device;
• and
• a displaying device configured to display an overlay image with the captured image and, according to the code marker, a marking of the code for adding assisting visual information to the code in order to provide an improved overview of the computer-readable codes to the user.
