1.3.11 Barcode Scanners
A barcode scanner is located on the mullion of each instrument. The scanner is designed to allow
one-handed vial barcode scanning by providing a bottle rest to assist in positioning and bottle rotation.
The barcode scanner is used to scan vial sequence and user-provided accession barcodes.
1.3.12 Software and Operation Overview
The Liquid Crystal Display (LCD) presents all the information needed to monitor instrument and station
status, to enter and remove vials, set up the instrument, print reports, and perform routine instrument
maintenance. The information is presented in the form of icons that graphically represent the
information (such as a clock to indicate the current time), text buttons, or a combination of icons and
text.
Operations you perform at the instrument can be initiated by opening a drawer and scanning a vial
(“vial activated workflow”) or can be initiated by selecting buttons, tabs, and fields on the LCD
touchscreen (“screen activated workflow”). Routine operations, such as entering vials and removing
positive vials, are initiated from the Status display. A Reports tab provides access to the built-in
BD
BACTEC FX reports, while Maintenance and Configuration tabs provide access to these functions.
Positivity analysis (algorithm subsystem)
Algorithms determine vial positivity (i.e., the detection of microbial growth). Multiple algorithms are
used to test for vial positivity. Some algorithms are medium specific for greater sensitivity.
If a sequenced vial has not triggered a positivity algorithm by the end of the defined protocol
length, and there are no instrument error conditions that would prevent accurate detection of
positives, the vial is declared a negative vial, however, positivity algorithms continue to be applied
until the vial is removed from the instrument.
Database
The database maintains the test measurements for each vial, vial identification and association
data, and patient demographic information. Data is stored in the BD
BACTEC FX database in both
standalone and BD
EpiCenter configurations. In addition, associated instrument errors, and
operating conditions (e.g., test times, instrument temperature, etc.) are stored in the database.
The database stores vial results for up to 60 days after removal from the instrument (readings are
maintained for up to 14 days).
NOTE
Accepted barcode symbologies include Code 128, Codabar,
Code 39, and Interleaved 2 of 5.
