Non-Invasive Sputum Removal: QIJIA’s MIE Device & Vest Airway System

For patients with COPD, cystic fibrosis, or neuromuscular disorders, mucus buildup in the airways isn’t just uncomfortable—it’s a silent threat that increases infection risk and reduces lung function. Traditional manual clearance methods often fail to provide consistent relief, especially for those with weak coughs. As a CE-certified factory manufacturer, QIJIA addresses this crisis with four innovative solutions: the HFCWO airway clearance system, MIE Cough Assist Device, the vest airway clearance system, and Vest therapy system for mucus clearance. Each device combines non-invasive technology with medical-grade safety, turning daily respiratory care from a struggle into a simple routine.

HFCWO Airway Clearance System: Pneumatic Oscillation for Targeted Mucus Removal

The HFCWO airway clearance system stands as QIJIA’s core solution for non-invasive sputum evacuation, leveraging advanced pneumatic high-frequency oscillation technology. This system operates on a simple yet powerful principle: it delivers rapid, gentle oscillations to the airways through a specialized interface, creating pressure variations that loosen and break down thick mucus. Unlike invasive methods, it requires no insertion of tools into the airway, making it suitable for long-term use.

In practice, the treatment process is straightforward and comfortable. Patients wear a lightweight mask or mouthpiece connected to the system, which generates high-frequency pulses of air. These pulses vibrate the airway walls, dislodging mucus from the bronchial tree and moving it toward the upper respiratory tract, where it can be easily coughed up or cleared. The adjustable frequency and pressure settings allow healthcare providers to tailor the therapy to individual patient needs, ensuring optimal results for diverse conditions.

MIE Cough Assist Device: Simulating Natural Cough for Safe Sputum Evacuation

For patients who struggle with weak or ineffective coughs, the MIE Cough Assist Device offers a life-changing solution. This device mimics the body’s natural cough reflex through mechanical inhalation and exhalation (MIE) technology, providing safe and effective mucus clearance without straining the respiratory muscles. It is particularly valuable for individuals with reduced lung function or muscle weakness that impairs their ability to cough voluntarily.

The working mechanism of the MIE Cough Assist Device involves two key phases. First, it delivers a gentle positive pressure to inflate the lungs fully, expanding the airways and mobilizing mucus. Then, it rapidly switches to negative pressure, creating a "simulated cough" that pulls mucus upward and out of the airways. This two-step process replicates the physiological cough reflex, clearing mucus more efficiently than manual methods while reducing the risk of airway damage. The device’s user-friendly design and adjustable pressure parameters make it suitable for home use, empowering patients to manage their respiratory health independently.

The Vest Airway Clearance System & Vest Therapy System for Mucus Clearance: Wearable Comfort, Powerful Results

QIJIA’s the vest airway clearance system and Vest therapy system for mucus clearance redefine convenience in respiratory care, combining wearable design with effective mucus removal technology. These systems are ideal for patients who prefer a hands-free approach or have difficulty using masks or mouthpieces, offering consistent therapy with minimal effort.

Both systems operate on the principle of external high-frequency oscillation. Patients wear a lightweight, adjustable vest that wraps around the chest and abdomen. The vest is connected to a control unit that delivers targeted vibrations, which travel through the thoracic wall to the airways. These vibrations loosen mucus by breaking the adhesive bonds between mucus and airway walls, while also stimulating ciliary movement to enhance natural mucus transport. The vest’s ergonomic design ensures a snug yet comfortable fit, allowing patients to move freely during therapy—whether sitting, standing, or reclining.

What sets QIJIA’s vest systems apart is their versatility. The Vest therapy system for mucus clearance is calibrated to address mild to moderate mucus buildup, while the vest airway clearance system offers enhanced oscillation intensity for more severe conditions. Both are compatible with pediatric and adult patients, with size options to accommodate all body types.
