Lerong Bubble CPAP System – Neonatal Respiratory Support System

The Lerong Bubble CPAP System is a non-invasive respiratory support system designed primarily for spontaneously breathing newborns and premature infants who require continuous positive airway pressure (CPAP). Bubble CPAP works by delivering a continuous flow of humidified gas through a nasal interface while the expiratory limb is submerged in water. The depth of immersion generates the required positive airway pressure, while continuous bubbling indicates pressure generation. The system is designed to help maintain functional residual capacity, keep the airways and alveoli open, improve oxygenation and reduce the work of breathing. Bubble CPAP is commonly used for neonatal respiratory distress, including respiratory distress syndrome in premature infants and post-extubation respiratory support. Key Features Delivers continuous positive airway pressure (CPAP) Bubble pressure generation system for stable airway pressure Integrated air/oxygen blender Heated humidification system Adjustable FiO₂ concentration Adjustable CPAP pressure through water column Compatible with nasal prongs and nasal masks User-friendly pressure adjustment Compact mobile design Visual bubbling chamber for easy monitoring Audible and visual alarm system Suitable for continuous neonatal respiratory support. Technical Specifications Therapy Mode Bubble CPAP FiO₂ Range 21–100% CPAP Pressure 3–10 cmH₂O Gas Flow 2–15 L/min Patient Type Neonates & Infants Humidification Heated Servo-Controlled Humidifier Pressure Generation Water Bubble Chamber Patient Interface Nasal Prongs / Nasal Mask Power Supply AC 100–240 V, 50/60 Hz Mobility Trolley Mounted System Components A typical Bubble CPAP system consists of: Air/Oxygen blender Flowmeters Servo-controlled heated humidifier Humidification chamber Inspiratory breathing circuit Expiratory breathing circuit Bubble generator (water chamber) Pressure adjustment tube Nasal prongs Nasal mask Head cap and fixation straps Overflow water collection chamber Mobile stand with accessories. Operating Principle The Bubble CPAP system delivers a blended mixture of oxygen and air through a heated humidifier before reaching the infant via nasal prongs or a nasal mask. Positive airway pressure is generated by immersing the expiratory limb of the breathing circuit into a water chamber. The depth of the tube below the water surface determines the CPAP pressure, while the bubbling action provides gentle pressure oscillations that help maintain alveolar recruitment and improve gas exchange.
