Mil-Spec Mechanism

Zigzag lift column + zinc-alloy screw-drive crank: Eliminates wobbling (±1° positioning accuracy)

1.2mm reinforced steel-stamped bed: Distributed load design increases deformation resistance by 30%

Embedded joint protectors: Block dust intrusion, extend screw drive service life  

Comprehensive Safety System

Dual fall prevention: Yellow/black guardrail stripes + mechanical auto-lock (response time <0.5s)

360° pinch-free design: Foldable cranks, zero exposed sharp edges

ABS impact-resistant edges: 6mm thickened head/footboard buffer layer (IK08 impact rating)  

Clinical Adaptive Engineering

Optimized backrest torque: Only 18N·m force required at 85° sitting position

Low-height mode (740mm): 120mm ground clearance for wheelchair/stretcher transfer

Ventilated bed base: 12 longitudinal airflow channels reduce pressure ulcer risk  

Post-Acute Care  

Rehabilitation centers: Detachable panels accommodate traction devices; screw-drive enables 15-min interval repositioning  

Edge: Meets ISO 10535 positioning standards with 35% lower crank force vs industry average  

Elderly Mobility Support  

Nursing homes: Dual-stage guardrail locks maintain seated position for 60-min static loading  

Edge: Passed EN 1970 fatigue test (7500 lift cycles with zero structural degradation)  

Home-Based Care  

Home ICU: 1030mm narrow profile clears standard doorways; <35dB caster noise ensures undisturbed sleep  

Edge: Alcohol-resistant ABS components cut maintenance costs by 50%  

Q1: Does the product have international safety certifications? (e.g., CE/ISO)

A: The bed complies with target market safety standards (e.g., CE/ISO13485). Certificates will be provided based on destination country requirements.

Q2: Is the 250kg weight capacity suitable for bariatric patients? Can it be customized for higher weight?

A: The standard 250kg capacity meets most needs. Customized reinforcement (e.g., 300kg+) is available upon request.

Q3: Is the 895mm inner width suitable for European/American body types?

A: 895mm inner width aligns with global medical bed standards (typically 900-1000mm in EU/US), complemented by 1030mm outer width for optimal comfort.

Q4: Does the height range (440-740mm) facilitate wheelchair transfer and nursing tasks?

A: The 740mm high position aids wheelchair transfers, while 440mm low position reduces fall risks and aligns with caregiver ergonomics.

Q5: Can the aluminum guardrails prevent falls? Are they pinch-proof?

A: Reinforced aluminum foldable rails pass rigidity tests. Hinges include safety gaps to prevent finger pinching.

Q6: How is mobility and noise of silent casters on hard floors?

A: High-resilience rubber casters passed 72hr rolling tests with ≤40dB noise (below 50dB hospital night standard). Each caster has individual brakes.

Q7: What are the advantages of the arched lifting mechanism vs hydraulic systems?

A: The steel arch structure eliminates hydraulic leaks. Crank-driven screw rods ensure ±2mm precision over 10 years, reducing maintenance costs by 60%.

Q8: Does the ventilated bed design prevent pressure ulcers? How to sanitize it?

A: Perforated steel bedpan (≥35% open area) exceeds industry breathability standards. Epoxy-coated surfaces withstand sodium hypochlorite/alcohol disinfection.
