After successful 510(k) clearance, Hamilton Medical has released the new active humidifier Hamilton-H900 in the US. The device features improved ergonomics, ease of use, and facilitated handling, the company says.

The product release is a part of Hamilton’s focus on expanding its “Intelligent Ventilation” concepts to devices directly involved in critical care ventilation.

“Humidification is an important part of respiratory care. When we developed the Hamilton-H900 humidifier, we talked to many clinicians to understand what they would improve in conventional humidification,” said Jens Hallek, president of Hamilton Medical.

Easier handling of circuits, cables and connections, an improved user interface, reduction of rain-out, and increased safety were the most requested enhancements. The Hamilton-H900 aims at improving humidification in exactly these areas.



The Hamilton-H900 comprises only two components, which are delivered preassembled and ready to use: The wall-heated breathing set including the new all-in-one connectors, integrated temperature probe, water refill tube, Y-piece, and water chamber, and the humidifier base with the user interface and the heating plate.

This saves time, increases efficiency, and facilitates the handling of the humidifier, as well as reducing the risk of contamination. With no need to worry about extra cables to connect or disconnect anymore, the caregiver only needs to slide the water chamber into the humidifier and connect the breathing circuit to the patient.

Rain-out and temperature control

The breathing circuits for the Hamilton-H900 integrate the heater wires into the circuit wall. This eliminates the cold interface between heated breathing gas and ambient temperatures, and leads to significantly reduced condensation and rain-out effects in the breathing circuit.

To perfectly adapt the humidification therapy to the individual patient and environmental conditions, the Hamilton-H900 humidifier allows for manual adjustment of the chamber temperature and temperature gradient. Having too much condensation in the tubing can, therefore, be avoided by adjusting the temperature gradient.

By reducing the need to open the circuit to drain condensate, the Hamilton-H900 minimizes the potential for the spread of pathogens associated with the development of ventilator-associated pneumonia (VAP).

Ergonomic and intuitive user interface

Due to the ergonomic design, the user interface can be easily seen and operated from a standing position, and provides all the information the caregiver needs at a glance. The large, high-contrast LC display provides excellent readability, even in direct sunlight.

Alarms are displayed with self-explanatory icons on the LC display, and can be heard and seen from afar thanks to the bright alarm lamps and audible alarm.
