Heat and Moisture Exchanger with Filter - Mini In-Line, 26.77mL, 99.9% Bacterial/Viral Filtration

Advanced Heat and Moisture Exchanger with Integrated Filtration

This professional-grade mini in-line heat and moisture exchanger (HME) with integrated bacterial/viral filter delivers superior airway humidification and breathing system protection for mechanically ventilated patients. Engineered as a true hygroscopic condensing humidifier (HCH), this device captures exhaled heat and moisture from the patient's breath and returns it during inhalation, maintaining optimal airway humidity levels while providing exceptional filtration efficiency exceeding 99.9% for bacterial and viral pathogens. The compact mini design accommodates tidal volumes from 150 mL to 1000 mL, making it suitable for both pediatric and adult patient populations across critical care, anesthesia, and respiratory therapy applications.

Hygroscopic Technology for Maximum Performance

Unlike passive HMEs that rely solely on condensation, this advanced hygroscopic design incorporates a physiologically safe calcium chloride-treated membrane that actively traps and retains patient moisture with exceptional efficiency. This hygroscopic membrane technology delivers superior moisture output compared to standard heat and moisture exchangers, ensuring effective airway humidification even during extended ventilation periods. The true HCH design achieves maximal humidification performance without potentially harmful chemicals, using only biocompatible materials that are safe for prolonged patient contact. High moisture retention characteristics prevent airway desiccation, reduce secretion viscosity, and support mucociliary function for improved respiratory outcomes.

Dual-Function Protection: Humidification and Filtration

This dual-purpose device simultaneously provides two critical functions in a single compact unit. The heat and moisture exchange component maintains physiologic airway humidity by capturing exhaled heat and water vapor, then returning it to the patient during the next breath cycle. Concurrently, the integrated bacterial/viral filter provides bidirectional protection with filtration efficiencies exceeding 99.9%, preventing cross-contamination between patient and breathing circuit. This effective filtration reduces the risk of ventilator-associated infections, minimizes colonization in breathing tubes, prevents sampling line blockage, and protects downstream equipment from pathogen exposure. The combination of humidification and filtration in one device simplifies circuit setup, reduces connection points, and decreases potential leak sites.

Mini In-Line Design for Versatile Applications

The compact mini configuration minimizes dead space while accommodating a broad range of tidal volumes from 150 mL to 1000 mL, making this HME suitable for pediatric patients, small adults, and standard adult ventilation. The in-line design integrates seamlessly into breathing circuits and allows for use with gas sampling elbows to fit user preferences and clinical protocols. Low resistance to airflow minimizes work of breathing and reduces imposed respiratory load on spontaneously breathing patients. The lightweight construction reduces circuit weight on endotracheal tubes and tracheostomy connections, decreasing traction forces that could cause patient discomfort or airway trauma.

Integrated CO2 Sampling Port for Monitoring

The conveniently-located luer connection permits end-tidal CO2 gas sampling at the top of the clear housing, positioned exactly as if a common gas sampling elbow were being used. This integrated sampling port offers convenient access to airway gases for capnography monitoring without requiring additional adapters or connections. Luer gas sampling ports ensure secure connection to monitoring equipment, preventing leaks and maintaining accurate CO2 measurements. The strategic port placement minimizes circuit manipulation during sampling line attachment, reducing disconnection risks and maintaining ventilation continuity during monitoring setup.

Optimal for Multiple Ventilation Applications

This versatile HME supports diverse clinical scenarios requiring short-term airway humidification and breathing system protection. In intensive care units, it provides humidification for mechanically ventilated patients during transport, procedures, or as an alternative to heated humidification systems. Operating rooms utilize it for anesthesia circuit humidification during surgical procedures. Emergency departments rely on it for acute respiratory support and emergency intubations. Post-anesthesia care units employ it during emergence and recovery periods. Respiratory therapy departments stock it for ventilator weaning trials and non-invasive ventilation applications. The broad tidal volume range makes it suitable for pediatric ICUs, neonatal units (for larger infants), and adult critical care environments.

Enhanced Safety and Monitoring Features

The clear housing construction enables continuous visual assessment of humidification effectiveness and early detection of secretion accumulation that might increase resistance or compromise performance. Healthcare providers can quickly identify when the HME requires replacement based on visible moisture saturation or secretion buildup. The integrated CO2 sampling port facilitates continuous capnography monitoring for ventilation assessment, ensuring patient safety during mechanical ventilation. ISO-standard connections prevent misconnections and ensure compatibility with all standard ventilators, anesthesia machines, and breathing circuits. Low resistance design is particularly important for pediatric patients and those with compromised respiratory mechanics who cannot tolerate additional breathing work.

Quality Construction and Infection Control

Manufactured to rigorous medical device standards, each HME undergoes quality verification to ensure consistent filtration performance, appropriate moisture retention, and leak-free connections. The hygroscopic membrane is treated with precise amounts of physiologically safe calcium chloride to optimize moisture capture without introducing harmful substances into the breathing circuit. Single-use disposable design supports evidence-based infection prevention practices by eliminating cross-contamination risks associated with reusable humidification equipment. Individual wrapping maintains product sterility and cleanliness until point of use. Convenient case quantities support high-volume facilities while ensuring adequate stock for emergency and routine applications.
