Designed with patient comfort, clinician safety, and efficient workflow in mind.

The DAR™ closed suction system is designed to expel tracheal secretions and preserve airway clearance for patients with an artificial airway in place. Compared to open suctioning, closed suction systems have been shown to reduce the physiological impact of endotracheal suctioning to the patient and offer protection for the clinician.1

The DAR™ closed suction system features a replaceable catheter — a step forward in endotracheal suctioning. Post-suction catheter removal, facilitated by a self-sealing cap on the patient access valve, permits bronchoscopy, mucus sampling, or bronchoalveolar lavage (BAL) procedures. Available with dedicated ports for catheter rinsing and MDI drug delivery, the DAR™ closed suction system with replaceable catheter is ideal for diverse treatment needs.

Benefits of closed endotracheal suctioning

Closed suctioning offers many potential benefits compared to open suctioning, including continued delivery of oxygen and positive pressure, decreased nosocomial infection, and reduced staff exposure.2

  • Improved physiological impact:
    • Improved oxygenation and PEEP maintenance3
    • Reduced impact on intracranial pressures4
  • Effective secretion management4
  • Easy to use, requires shorter suctioning time, and uses only one nurse5,6
  • Supports clinician safety by minimizing exposure7

Features of the DAR™ closed suction system

Airway protection

The unique rotating patient access valve maintains airway isolation when suctioning isn’t required and ensures a closed system during bronchoscopy and specimen sampling.

Catheter rinsing

The irrigation port’s one-way valve is intended to prevent patient secretions from flowing back and potentially minimize contamination risks. The catheter tip is cleaned in full isolation through the rinsing chamber’s special geometry.

Clinician-friendly design

The suction valve’s rotating lid functions as an open-closed locking mechanism, providing easy procedure control. ISO color coding enables immediate catheter size identification, assisting caregivers in system selection, while depth markings in centimeters facilitate catheter insertion into the trachea.

Improving physiologic stability for your smallest patients

Neonatal-pediatric closed suction system

The DAR™ neonatal-pediatric closed suction system was developed with the same advanced technology from the adult version and boasts features tailored for neonatal and pediatric physiologic conditions.

  • A specialized rotating valve ensures patient airway isolation
  • Efficient suctioning in incubator maintained by no-kinking catheter feature
  • Variety of endotracheal tube adapters
  • Transparent valve body permits easy secretion inspection

Neonatal and pediatric benefits of a closed suction system

The use of a closed suction system, compared to open suctioning, can help minimize some short-term suctioning-related complications for newborn and pediatric patients by producing less cardiorespiratory distress.8

Potential benefits include:

  • Reduced occurrence of hypoxia8
  • Minimized bradycardia8
  • Faster recovery times2
