Product Introduction
The Disposable Heat and Moisture Exchanger (HME), also known as artificial nose, is a sterile single-use respiratory auxiliary medical consumable. It is installed between the endotracheal tube/tracheostomy tube and the breathing circuit, simulating the natural warming and humidifying function of the human upper respiratory tract. The product adopts high-efficiency hygroscopic and heat-preserving filter material, which can capture and store the heat and moisture in exhaled gas, and release them to inhaled air. It effectively reduces respiratory heat and water loss, keeps the airway moist, filters bacteria and impurities in the gas, and lowers the risk of lung infection. It is widely used in anesthesia ventilation, ICU mechanical ventilation and tracheotomy patient nursing, featuring simple operation, safe use and significant clinical effect.
Product Advantage
• Simulate Natural Respiratory Humidification: The high-performance hygroscopic material efficiently retains heat and moisture in exhaled air, realizes passive balanced humidification and warming of inhaled gas, avoids dry and cold gas irritation to the airway, and relieves respiratory discomfort such as dry throat and viscous sputum.
• Efficient Bacterial Filtration & Anti-infection: Equipped with high-density hydrophobic filter membrane, it can effectively block bacteria, dust and particulate impurities in the air, reduce the incidence of ventilator-associated pneumonia and respiratory cross-infection, and optimize hospital infection control.
• Low Breathing Resistance & Smooth Ventilation: Optimized internal structural design ensures low airflow resistance, does not increase patient breathing burden, maintains stable tidal volume and airway pressure, and adapts to long-term continuous ventilation treatment.
• Precision Universal Interface: Adopts international standard universal connector, perfectly compatible with various endotracheal tubes, tracheostomy tubes and anesthesia breathing circuits, with tight connection, no air leakage and convenient assembly and disassembly.
• Lightweight & Humanized Design: Mini lightweight shell structure, no burden on patient fixation, stable placement, not easy to fall off, suitable for adult, pediatric and various body position ventilation scenarios.
• Sterile Single-use & High Safety: EO sterilized, independent sterile packaging, single use only, completely avoiding cross-contamination caused by repeated use, with stable and reliable product performance.

Product Uses
• Intraoperative Anesthesia Ventilation: Used for gas humidification, warming and filtration during general anesthesia surgery, optimize intraoperative breathing environment, prevent airway dryness and irritation, and ensure stable intraoperative ventilation.
• ICU Mechanical Ventilation Care: Suitable for long-term mechanical ventilation of critically ill patients, replace the humidification and filtering function of the upper respiratory tract, reduce sputum scab formation, and lower the risk of ventilator-related lung complications.
• Tracheotomy Patient Nursing: Specialized for daily respiratory care of tracheostomy patients, make up for the loss of natural airway humidification function, keep airway secretions moist and easy to discharge, and improve patient breathing comfort.
• Postoperative Resuscitation & Oxygen Therapy: Applied for auxiliary breathing filtration and humidification in post-anesthesia recovery room to help patients recover spontaneous breathing smoothly and reduce postoperative respiratory discomfort.
• Emergency Respiratory Rescue: Used for temporary airway humidification and filtration protection in emergency intubation and respiratory rescue scenarios, ensuring safe and stable emergency ventilation.
Clinical Characteristics
• Passive Constant Temperature & Humidity Maintenance: Automatically capture and release heat and moisture according to breathing rhythm, maintain constant temperature and humidity in the airway, avoid excessive loss of respiratory water and heat, and effectively prevent sputum thickening and crusting.
• Dual Functions of Humidification & Filtration: Integrate respiratory gas warming, humidification and bacterial filtration functions, simplify clinical operation procedures, replace traditional active humidification equipment, and reduce nursing workload.
• Stable Ventilation & Low Trauma: Ultra-low resistance design will not affect mechanical ventilation parameters and spontaneous breathing of patients. It has no irritation to airway mucosa and is safe for long-term continuous use.
• Standardized & Cost-effective: Simple structure, complete compliance with clinical infection control standards, low use cost, suitable for large-scale and high-frequency clinical use.
Storage & Attention
• Storage Conditions: Store in a dry, cool, ventilated and clean environment, avoid high temperature, humidity, direct sunlight, heavy pressure and corrosive substances.
• Precautions: Single use only, prohibited for repeated use; do not use if the package is damaged, unsealed or expired; replace regularly according to clinical specifications; stop using immediately if blockage, water accumulation or poor ventilation occurs during use.
