SearchLiquoGuard® is the leading CSF management system that simultaneously measures CSF pressure and drains cerebrospinal fluid under controlled circumstances.
LiquoGuard® was designed to continually monitor for CSF drainage problems. It is a proactive system, unlike gravity-based drains which cannot actively monitor and detect issues. Our device will notify staff immediately when there is an occlusion, pressure discrepancies, catheter disconnections. This helps clinicians by knowing their external drain patients are being monitored closely and consistently - and only need to intervene when the device senses a problem with the drainage process. The system not only supervises the patient levels, but also supervises itself. Any inconsistency in the measured pressure leads to an alarm so that you will know immediately when a problem is detected.
Advantages Of LiquoGuard® Versus Gravity Drains: Gravity-based drip chambers are commonly used for external lumbar and ventricular drains, but are difficult to manage and fraught with problems, especially restrictions on movement and inadvertent "dumping" of CSF. Our automated CSF management technology, LiquoGuard®, is easy to program and manage, and eliminates many of the challenges associated with gravity-based drains.
There is now no need to:
- level a transducer each time the patient moves
- manipulate stopcocks
- choose between measuring pressure or draining CSF
- keep patient still while draining without risk of overdraining CSF
Handling mistakes are prevented, which greatly improves patient safety and leads to quicker recovery.
Vascular surgery and anestesiology
During vascular surgery intervention (e.g. TAA, TAAA) LiquoGuard® reliably monitors the pressure situation and the flow of CSF, documents the progression and helps detect situations that are harmful for the patient, early on. Also after an OP LiquoGuard® helps keep the intrathecal pressure at the desired level, or facilitates fast reaction to avoid neurological deficits or to counter them as quickly as possible. Typical application cases are:
- Intraoperative neurological monitoring
- Postoperative neurological monitoring
- Pressure controlled CSF drainage
Neurosurgical, accident surgery and orthopedics
LiquoGuard® is traditionally used to control and adjust the cerebrospinal fluid pressure for continuous and regulated drainage, and for relief of acute high-pressure events (bleeding, edema, etc.).
Patients of any age, pediatric as well as geriatric, profit, and for medical personnel the effort associated with supporting and monitoring the drainage is reduced. Typical application cases are:
- Ventricular drainage
- Lumbar drainage
- Pressure controlled drainage
- Volume controlled drainage
Diagnostic and therapeutic support
Diagnosis of NPH (Normal Pressure Hydrocephalus) is difficult at times. LiquoGuard® supports you through the possibility of performing automated diagnostic procedures (Lumbar infusion test, Tap Test, Continuous lumbar drain, Continuous pressure monitoring).
In addition, LiquoGuard® is suitable for determining possible shunt settings and can depict and record the actual life conditions of the patient. The fact that LiquoGuard® offers mobile implementation due to battery operation, enables drainage volumes and target ICP to also be determined quickly, easily and safely in different positions (lying, sitting, standing, physical exertion, etc.), even over a longer period of time. Typical applications are:
- Katzman Test (lumbar infusion for NPH diagnosis)
- Determination of shunt opening pressures and possible suitable shunt settings
- Control of shunt settings and functionality
