The LiquoGuard® CSF Management from Möller Medical
LiquoGuard® (Liquor = German for CSF) represents a revolutionary step in CSF drainage, maximizing patient safety, reducing costs and enhancing mobility while offering a versatile medical tool.
SAFETY: Common problems of conventional external CSF drainage systems are incorrect adjustment of the dripping chamber (e.g. during mobilisation, CT, angiography, OR) and unrecognized pressure sensor malfunction (sensor drift). LiquoGuard’s dual pressure sensor technology (DPST), redundant microcontrollers, and sophisticated alarm concept reduce patient risks significantly. E.g., LiquoGuard® constantly monitors the normal CSF pressure pulsation and thus helps detect catheter occlusions. LiquoGuard’s closed system operates without air filter, minimizing infection risks.
COST REDUCTION: LiquoGuard® by design does not require any height adjustments of dripping chambers, thus saves cost and allows staff to concentrate on their essential tasks.
MOBILITY: Thanks for powerful rechargeable batteries, the system is independent of external power supply and allows pressure control unaffected by any movement of the patient. Even an earlier transfer from ICU/high care stations may be considered*.
VERSATILITY: The LiquoGuard® system can be easily connected by Luer-Lock connector to most commercially available lumbar and ventricular drainage catheters. CSF pressure and flow is permanently recorded and displayed bedside. For further analysis, data may be transferred (by storage card) to a PC.
SAFETY: Conventionally, discontinuous and uncontrolled lumbar CSF drainage may lead to catheter occlusions, intracranial hypotension, collapsed ventricle or subdural haematoma. LiquoGuard® supports detection of catheter leakage and helps avoid catheter occlusions by a continuous CSF flow.*
COST REDUCTION: The electronically controlled LiquoGuard® CSF management eliminates the need for time consuming manual adjustments of exact CSF drainage flow.
MOBILITY: The LiquoGuard® sensor unit is easily taped and adjusted to the lumbar catheter level using a specially designed fixation device for maximal patient comfort and mobility.
VERSATILITY: LiquoGuard® is the worldwide first CSF management system permitting a continuous pressure-controlled CSF flow.
SAFETY: CSF flow is controlled by the desired intracranial pressure (ICP in mmHg) and limited by the pre-selected max. flow rate (ml/h). Pressures below zero are never generated (no “suction”).
COST REDUCTION: There is no dripping chamber and thus no need for time consuming manual height adjustments.
MOBILITY: Pressure measurement and control is continuously provided even during transportation of the patient.*
VERSATILITY: Continuous documentation of ICP and CSF volume helps in decision making for permanent CSF shunting, analyzing effects of medications on CSF flow and calculating ventricular compliance.
