AVE-562 Fully Automated Feces Analyzer
The AVE-562 is a fully automated benchtop feces analyzer processing up to 90 samples/hour with fluorescence microscopy and AI-assisted particle recognition for comprehensive fecal analysis. Optimized for clinical labs, it detects parasites, ova, leukocytes, RBCs, and yeast in <10 minutes per sample, featuring touchscreen interface, built-in printer, 50,000-result storage, and LIS integration for efficient infectious disease screening.
Description
Sample Processing: Automated Fecal Particle Analysis The AVE-562 automates the detection and classification of fecal elements, identifying parasites (e.g., Giardia, Entamoeba), ova, cysts, leukocytes, red blood cells, yeast, and fat globules through fluorescence staining and digital imaging. This enables rapid diagnosis of gastrointestinal infections, inflammatory bowel disease, or malabsorption syndromes, providing quantitative counts and morphological insights to guide targeted therapies like antiparasitics or anti-inflammatories in gastroenterology clinics or infectious disease labs.
Parameters Measured: Analyzes multiple fecal components with high specificity: parasites/ova (0–500/µL), leukocytes (0–1000/µL), RBCs (0–500/µL), yeast/bacteria (0–1000/µL), and fat (0–50%), using dual fluorescence (FITC for parasites, DAPI for nuclei) and bright-field imaging. Generates digital images, particle counts, and reports with >95% accuracy and CV <5%, including alarms for critical thresholds like >50 leukocytes/µL indicating infection; supports formed/unformed samples with recycling rate >80% for residue handling.
Sample Requirements: Requires 0.5–2 mL of fresh or preserved feces (e.g., in PVA or SAF), processed via automated pipetting and staining without manual dilution. Compatible with random or timed collections, with STAT priority slot for urgent samples; minimizes biohazard exposure through sealed cassettes, suitable for high-risk pathogens in pediatric or immunocompromised patients.
Throughput: Achieves up to 90 samples per hour in random access mode, ideal for mid-sized labs handling 500–1,000 tests daily. The 8–10 minute cycle per sample with continuous loading supports peak workloads, such as outbreak investigations or routine GI panels, reducing turnaround time from hours to minutes.
Technology: Integrates fluorescence microscopy with AI-driven image recognition for automated particle segmentation and classification, using a 10 MP CMOS camera and LED excitation (365/470 nm). The closed-loop staining system ensures consistent dye uptake, while machine learning algorithms differentiate artifacts from true positives with >98% sensitivity; barcode reading verifies sample ID and expiry, aligning with CLSI guidelines for automated microscopy.
User Interface and Storage: Features a 10.4-inch color touchscreen with graphical dashboards for real-time imaging and result review, supporting up to 10 languages (English, Chinese, Spanish). Stores up to 50,000 results with images, counts, and patient data in a searchable database; built-in thermal printer outputs customized reports, with USB/RS232/LAN for HL7 LIS integration and PDF/CSV exports for electronic records.
Reagent System: Uses proprietary fluorescent stains and diluents in cartridge format (500-test packs, 12-month shelf life at 2–8°C), with on-board mixing to prevent cross-contamination. Automated two-level QC and low-waste dispensing (0.2 mL/sample) reduce costs by 40%, with alerts for reagent expiry; open architecture allows third-party compatibility for expanded panels.
Dimensions and Portability: Benchtop design measuring 450 × 350 × 500 mm (W × D × H) weighs 25 kg, fitting standard lab benches with optional wheeled cart. Operates quietly (<50 dB) on AC 100–240V with ≤200 VA power, enduring 10–35°C ambient and 20–80% humidity for versatile installation.
