Breathing circuit sets

  • User-friendly as flow sensor, tube, connectors and expiratory valve set are all preassembled
  • Heated for humidification with the HAMILTON-H900 or nonheated breathing circuit sets
  • Reduced risk of Ventilator Associated Pneumonia (VAP) due to single patient use

We offer preassembled breathing circuit sets with proven manufacturer quality – all sets have been specially developed for Hamilton Medical ventilators. Our single-use breathing circuit sets are available in several different lengths and assemblies – with and without flow sensor and/or expiratory valve – to meet your individual requirements.

Coaxial breathing circuit sets

The coaxial design allows passive warming of inspiratory gases due to heat exchange with the expiratory flow. The user benefits from greater time and cost efficiency as the sets are preassembled and designed for single use, so reprocessing is eliminated.

Single use also reduces the risk of cross infection. Optimal positioning is possible thanks to the expandable expiratory tube.

Depending on your needs, you can order customized sets with or without a flow sensor and/or expiratory valve.

Heated breathing circuit sets for active humidification with the HAMILTON-H900

Both limbs of the preassembled set 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 in the breathing circuit.

The cable-free breathing circuit sets feature a built-in temperature probe and electrical connection. This saves extra work and reprocessing. Furthermore, the circuits include a water refill tube, Y-piece, and a water chamber with an automatic refill mechanism. The sets are available as single or dual limb and can be used on a patient for up to 28 days.

The breathing circuit sets for neonatal and pediatric patients include a detachable, unheated extension for use in incubators, and are designed for patients up to 15 kg.

Breathing circuit sets for neonatal and pediatric patients

This dual limb set includes all parts for neonatal ventilation: circuits, flow sensor, pressure line, calibration adapter, elbow connectors, swivel Y-piece and the neonatal expiratory valve.

It is very handy to get the breathing set as one. All we have to do is open the package, insert the complete set and connect it. It makes our job easier.
