Brain fluid pressure

Microfluidics can be used in various medical fields. This includes measuring brain fluid pressure. The Cerebral and Cochlear Fluid Pressure (CCFP) analyser can detect life-threatening head injuries and infections without the need for surgery or painful spinal procedures. It can help combat space-related vision problems and diseases in astronauts – so-called “fluid shifts.”

About Space Vision

Our customer Space Vision is using microfluidics for a particularly exciting application: to measure brain fluid pressure. The device developed enables non-invasive (non-surgical) measurement of brain fluid pressure.

In most people, there is a fluid connection between the brain and the inner ear.  Therefore, Space Vision can assess intracranial pressure by measuring inner ear pressure.

The device uses a standard clinical technique: tympanometry. This requires a very accurate, and preferably small, air pump. Our mp6 micropump is used here. The frequency of the micropump is carefully selected so that it does not interfere with the acoustic measurements and the brain fluid pressure can be accurately determined.
