In today as health care environment, maximizing efficiency and minimizing waste are more important than ever. This increased efficiency must be achieved without compromising patient care. The Circulaire; II High-Efficiency Aerosol Drug Delivery System delivers equivalent drug delivery with improved clinical outcomes, in a fraction of the time - and with less waste of medication.

The unique lightweight reservoir captures aerosol during the patient as expiratory phase and retains it for “On-Demand Delivery” during the subsequent inspiratory phase. The combination of aerosolized medicine generated by the VixOne nebulizer, and that which is inhaled from the reservoir ensures the maximum percentage of a patient as tidal volume is medicated.

Positive Expiratory Pressure (PEP) therapy drives air into the lungs and behind the mucus using collateral airways. PEP therapy can easily be incorporated when using Circulaire II as it is included as a standard feature. Set the expiratory variable resistor to the minimal opening and you have simulated pursed lip breathing as part of the delivery system. During the exhalation phase, exhaled air (yellow) holds the one-way flapper valve shut and directs the exhalation out through the filter and the variable expiratory resistor. Meanwhile, the nebulizer, which is operating continuously, inflates the reservoir bag with its aerosol output.

When the subsequent inhalation begins, the patient inhales and receives aerosol from BOTH the nebulizer and the reservoir bag (light blue).

Consequently, there is little or no room air entrainment to dilute the inspired aerosol. Because the patient receives aerosol from two sources simultaneously (nebulizer plus reservoir), the inhaled mass of drug to the patient is approximately double what the patient would receive from any other non-reservoir device.

Understanding this set of repetitive steps that occur during inhalation and exhalation within the Circulaire system, as depicted in the animation above, is key to appreciating how the device is able to perform so much better than all other disposable jet nebulizers.

The Circulaire II can be administered with the use of a mask or mouthpiece. By design, the Westmed swivel mask alleviates cumbersome posturing of the patient as this unique characteristic allows you to accommodate your patient as position. These features plus others make for a very versatile and universal pulmonary drug delivery system.

The system includes a detachable reservoir bag. Bag replacement simplifies the delivery of a variety of aerosolized medicines such as bronchodilator therapy, antibiotic therapy, mucolytics, antifungals, etc.

Traditional SVN as typically release a high percentage of aerosol to the environment during the patient as exhalation phase. Depending on the patient as inspiratory/expiratory ratio, Circulaire II can deliver up to 300 percent more aerosolized medicated flow volume than the best continuous or breath-actuated nebulizers.

Two of the standard features included with the Circulaire II make this device the ideal product for hospital and home care use. Through the use of the reservoir and expiratory filter, Circulaire II provides a closed system. These attributes benefit both patient and provider - improved clinical outcomes for the patient, less risk of exposure to exhaled aerosols for the provider.

Features:

• Pneumatic jet nebulizer utilizes conserver principle to double the rate of drug delivery
• Thin, polyethylene reservoir bag designed to inflate and deflate more readily
• Top-hinged, 1-way flapper valve responds to patient's inspiratory effort without blocking the flow of aerosol particles
• Expiratory variable resistor allows clinician to optimize breathing pattern for enhanced pulmonary deposition
