Spirale DDS

Spirale® DDS

Spirale DDS Counter

Spirale® DDS is the smart way to deliver aerosolised micro-drug particles from an MDI (metered dose inhaler) canister into a respiratory breathing circuit during anaesthesia or intensive care ventilation in the spontaneously breathing or ventilated patient.

Clinical Efficacy

Clinical efficacy of MDI volumising chambers has been established through independently-published scientific research3.

Such data demonstrates superior alveolar drug deposition when a volumising chamber is used in conjunction with an MDI in comparison to nebulisation of drug fluid using a gas-driven jet nebuliser. Dosage of medication should be assessed based on MDI expellant volume, which is normally quantified in micrograms per actuation and be titrated using urine excretion analysis or other accepted physiological indicators.

Optimal Drug Delivery

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 connector4.

 

Closed-circuit

Spirale® DDS is intended to remain in the breathing circuit, thus negating the risk of environmental contamination of the breathing circuit and clinical setting, common with the use of gas-driven fluid nebulisers.

It also avoids the need to change ventilation settings when utilised. Closed-circuit suctioning of the patient’s airway can continue with the Spirale® DDS in place.
