Spirale® DDS is intended to remain in the breathing circuit reducing the risk of environmental contamination of the breathing circuit and clinical setting. Spirale® DDS is a collapsible volumising spacer device designed to deliver aerosolised micro-drug particles from an MDI canister, specifically intended for delivery of pulmonary medication. Spirale® DDS optimises alveolar drug deposition using a carefully designed jet orifice in combination with volumising geometry. Spirale® DDS can be positioned in the inspiratory limb of the breathing circuit or is equally suitable in a catheter mount or connected directly to the patient connector. Key features Optimal drug delivery Universal actuator port Compatible with MDIs with dose counters Rotational locking system Self-expanding when unlocked Low (16ml) dead space when closed Eliminates environmental drug pollution Maintains a closed breathing circuit Avoids disruption to ventilation settings Does not require additional oxygen
