Abstract

A bar code reader (2) for a medical device (3) is configured to be attached to a central communication device (1) to which at least one medical device (3) is attachable. The bar code reader (2) comprises a bar code scanning device (21) for scanning a bar code (4), a processing device (22) for decoding the scanned bar code (4) to obtain decoded bar code data which is contained in the scanned bar code (4), and a connection line (24) for outputting the decoded bar code data to the central communication device (1). The processing device (22) herein is operative to decode bar codes (4) of different bar code types. Furthermore, the processing device (22) is configured to map the decoded bar code data to a predefined standardized output format and to output the decoded bar code data in the predefined standardized output format via the connection line (24). Thus, a bar code reader and a method for processing a bar code scanned by a bar code reader are provided which are capable of reading and interpreting bar codes of a variety of different types and allow for outputting the data contained in a bar code in a manner such that a central communication device to which the bar code reader is attached may easily interpret the data.

Claims

1. A bar code reader for a medical device, wherein the bar code reader is configured to be attached to a central communication device to which at least one medical device is attachable, the bar code reader comprising:

a bar code scanning device for scanning a bar code;

a processing device for decoding the scanned bar code to obtain decoded bar code data which is contained in the scanned bar code, wherein the processing device is operative to decode bar codes of different bar code types; and

a connection line for outputting the decoded bar code data to the central communication device, wherein the processing device is configured to map the decoded bar code data to predefined fields of information of a predefined standardized output format and to output the decoded bar code data in the predefined standardized output format via the connection line, and wherein the processing device is configured to check whether the scanned bar code contains all information corresponding to the predefined fields of information that beforehand have been defined as essential.

2. The bar code reader according to claim 1, wherein the standardized output format is XML format.

3. The bar code reader according to claim 1, wherein the processing device is configured to map the decoded bar code data to predefined fields of information of the standardized output format.

4. The bar code reader according to claim 1, wherein the scanned bar code contains at least one of:

patient identification information to identify a patient;

employee identification information to identify an operator for operating a medical device;

drug identification information for identifying a drug to be administered via a medical device, and device identification information to identify a medical device.

5. The bar code reader according to claim 1, wherein the scanned bar code complies with the HIBC standard.

6. The bar code reader according to claim 1, wherein the bar code reader is programmable to configure the processing device to map the decoded bar code data to the predefined standardized output format.

7. The bar code reader according to claim 1, wherein the processing device checks whether the scanned bar code conforms to a valid bar code type.

8. The bar code reader according to claim 1, wherein the processing device is configured to check whether the information of at least one field matches specific criteria of minimum and maximum number of characters and/or illegal characters.

9. The bar code reader according to claim 7, wherein the processing device is configured to produce an alert in case an error is detected.

10. The bar code reader according to claim 7, wherein the barcode reader is configured to output an error message via the connection line to be displayed by the central communication device or a medical device attached to the central communication device in case an error is detected.

11. The bar code reader according to claim 1, wherein the bar code is of a linear bar code type or a two-dimensional bar code type.

12. The bar code reader according to claim 1, wherein the bar code type complies with CODE128 standards, PDF417standards, Data Matrixstandards or Aztec standards.

13. The bar code reader according to claim 1, wherein the connection line is releasably connectable to the central communication device.

14. A method of processing a bar code scanned by a bar code reader for a medical device, wherein the bar code reader is configured to be attached to a central communication device to which at least one medical device is attachable, the method comprising the steps of:

scanning a bar code using a bar code scanning device of the bar code reader, decoding the scanned bar code using a processing device of the bar code reader to obtain decoded bar code data which is contained in the scanned bar code, wherein the processing device is operative to decode bar codes of different bar code types, and

outputting the decoded bar code data to the central communication device via a connection line of the bar code reader, wherein the processing device maps the decoded bar code data to predefined fields of information of a predefined standardized output format and outputs the decoded bar code data in the predefined standardized output format via the connection line, and wherein the processing device checks whether the scanned bar code contains all information corresponding to the predefined fields of information that beforehand have been defined as essential.
