The original physiologically designed siphon control mechanism, the Anti-Siphon Device, is normally open and reacts only as needed to changes in hydrostatic pressure. When a patient sits or stands, the device resists the hydraulic siphoning common to differential pressure CSF-control valves, preventing over-drainage and keeping the patient’s intra-ventricular pressure within the physiological normal range.
Key Features:
- The Anti-Siphon Device (ASD) may be connected in series with any flushing reservoir or proximal control valve using the connectors packaged with the device
- The ASD is an integral component of many Natus valve systems
- Pudenz Straight Connector included
