Mindray BS-240 Bi-Directional LIS Interfacing Guide
Complete engineering specification, HL7/ASTM protocols, pinouts, and parameter mapping for Mindray BS-240 on AILS Cloud LIMS.
1. Instrument Overview & Interfacing Architecture
The Mindray BS-240 is a high-performance biochemistry instrument designed for diagnostic laboratories and hospital health networks. Integrating this analyzer directly with AILS Cloud LIMS eliminates manual transcription delays, prevents typographical patient identification errors, and automatically enforces Westgard delta check algorithms.
AILS automatically generates worklist queries (QRY^Q02 / ASTM orders) mapped to patient accession barcodes and pushes test instructions directly to the instrument sample tray.
Raw OBX / Result records are parsed instantly within 200 milliseconds, flagged for abnormal reference ranges, and linked to pathologist digital signature queues.

Frequently Asked Questions: Mindray BS-240 Interfacing
Common biomedical engineering questions regarding connection, worklist setup, and data capture with AILS Cloud LIMS.
Q: What interface standard does Mindray BS-240 use?
Mindray BS-240 uses HL7 v2.3.1 or HL7 v2.5 over TCP/IP MLLP socket (Port 5001).
Q: Does Mindray BS-240 support bi-directional sample queries?
Yes. When a tube barcode is read on the sample carousel, BS-240 queries AILS LIMS and downloads the requested chemistry panel.
Q: How are biochemistry panel test codes mapped?
Short test codes (e.g. GLU, CREA, SGPT, SGOT, BIL-T, UREA) are mapped to standard LOINC codes in AILS LIMS.
Q: How are auto-dilution results processed from BS-240?
If an analyte concentration exceeds the linearity range, BS-240 applies automated dilution and transmits the multiplied result with flag D.
Q: Can Mindray BS-240 calibration and QC data be tracked?
Yes. QC results are routed to AILS Levey-Jennings quality management module automatically.
