Bistos BT-400 Neonatal Phototherapy Unit

Description

Design and Protection Mechanism: Stand-Type LED Configuration The Bistos BT-400 is a portable, stand-type neonatal phototherapy unit engineered for targeted treatment of physiological and pathological jaundice in newborns, preventing kernicterus by accelerating bilirubin breakdown without the risks of traditional UV or halogen lights. Featuring a lightweight aluminum alloy frame with a powder-coated finish for corrosion resistance and easy wipe-down, it includes a stable rolling stand with lockable casters (optional) for mobility between bassinets or incubators. The double-walled LED head (polycarbonate enclosure, IPX3-rated) minimizes heat transfer to the infant’s skin, while safety features encompass overheat cutoffs, timer-based auto-shutoff (up to 99 hours), and eye shields compatibility, ensuring compliance with ISO 80601-2-73 and AAP guidelines for non-invasive phototherapy.

Performance and Irradiance Control: Emits focused blue LED light (450–470 nm peak wavelength) with irradiance up to 40 µW/cm²/nm over a 30 × 50 cm effective treatment area, achieving >30% bilirubin reduction in 24 hours for most cases. The adjustable intensity (high/low modes) allows customization based on serum levels (e.g., high for >15 mg/dL), with uniform distribution via multi-array optics to avoid hot spots. The flexible gooseneck (180° rotation, 30 cm extension) positions the light 30–50 cm above the infant, while real-time monitoring prevents overexposure, supporting intensive or maintenance therapy in preterm or full-term neonates.

Light Head and Accessibility: The compact LED head (25 × 15 cm) tilts 90° and swivels 360° for optimal coverage of the abdomen, back, or full body when combined with fiberoptic blankets (optional). The built-in clamp secures to incubators or warmers, with a 1.5 m height adjustment (80–150 cm) for supine/prone positioning. The low-profile design (15 cm height) integrates seamlessly with overhead warmers, providing unobstructed access for nursing while maximizing irradiance without direct skin contact.

User Interface and Operational Features: A vivid 2.4-inch TFT color LCD displays operating time, total usage hours, intensity mode, and irradiance levels, with simple button controls and multilingual support (up to 6 languages, including English and Korean) for intuitive setup. Programmable timer (1–99 hours) with audible end-of-cycle alerts prevents overtreatment, while the low-noise fan (<45 dB) maintains a soothing environment. Optional remote control enables adjustments from outside the isolette, and integration with EMR systems via RS232 logs treatment sessions for compliance tracking.

Sterilization and Maintenance: The smooth, non-porous head and stand wipe clean with 70% isopropyl alcohol or EPA disinfectants, with detachable panels for thorough decontamination. The maintenance-free LEDs require no bulb changes for 20,000 hours, and self-diagnostics alert for power or sensor issues. Annual filter cleaning and firmware updates via USB ensure longevity; the unit’s modular design allows head replacement in <5 minutes, backed by a 2-year warranty for reliable NICU deployment.

Electrical and Environmental Specifications: Powered by AC 100–240V/50–60Hz at 50W with universal adapter and surge protection for global use. Operates in 10–35°C ambient with ≤80% RH, featuring EMI shielding (IEC 60601-1-2) to avoid interference with monitors or ventilators. Energy-efficient LEDs reduce heat by 80% vs. fluorescent, with auto-standby after 30 minutes to conserve power.

Dimensions and Portability: Stand-alone unit measures 800 × 400 × 1,200 mm (H × W × D) weighs 8 kg, with foldable arms for compact storage (0.5 m³). The rolling stand (optional) includes 4 casters for easy transport; setup takes <1 minute, fitting standard NICU bays or mobile carts.

• Throughput and Workflow: Treats 4–8 neonates daily with 1–3 hour sessions, enabling quick repositioning for combo therapy with incubators.
• Detection and Monitoring: Integrated irradiance sensor (±5% accuracy); logs 1,000 sessions for audits.
• Detection Principle: Blue LED array (450–470 nm) for photoisomerization of bilirubin into excretable forms.
• Additional Features: Flexible neck for multi-angle coverage; compatible with eye shields and fiberoptic panels; remote timer control.
• Data Storage: 500 treatment records (duration, intensity) exportable via USB in CSV.
• Patient Handling Modes: Supine/prone jaundice therapy; integrable with warmers/incubators for preterm care.
