Abstract

The measurement of "CSF pressure" has an important role in diagnosis of many nervous system disorders and measuring brain functions after head trauma. Plastic manometers currently being used for this purpose have some undesirable effects. During lumbar puncture, a spinal needle (10 cm long needle inserted from the lumbar vertebrae into the cerebrospinal fluid) is used to reach the cerebrospinal fluid in subarachnoid space ( the compartment which CSF circulates in brain and spinal space). Without any contact with the CSF and the spinal needle, CSF pressure can be measured via calculating the time between CSF drops contacting with a digital surface (digital sensor) clearing the need to use plastic manometers for this purpose. This method is first and unique method in CSF measurement applications. The device consists of an infrared sensor and a digital circuit and a chronometer to make digital calculations. The time between each CSF drops touching the infrared sensor is detected by a digital circuit and converted to CSF pressure by the measuring instrument loaded in the digital circuit. Key words: CSF pressure measurement device intracranial pressure lumbar puncture CSF openning pressure spinal needles spinal puncture
