Lumbar punctures, also known as spinal taps, are diagnostic procedures involving the removal of cerebrospinal fluid (CSF) from the space around patient’s spinal cord. CSF is the fluid that protects your brain and spinal cord. A lumbar puncture is a procedure in which a needle is used to access the space around the spinal cord. CSF moves through this needle and drips into a collection vial. CSF is collected in order to diagnose meningitis and other serious infections, bleeding near the brain, certain cancers, and inflammatory conditions affecting the nervous system. Frequently, dehydration and low pressure cause the CSF to drip very slowly into the collection vial, often forming a “bead” or “bubble” at the end of the needle before dripping into the vial. Such bubbles further slow down the CSF collection process, temporarily acting like a dam before the bubble eventually bursts, allowing the fluid to flow. Attempts to “burst” the bubble often result in spillage and loss of CSF during the procedure.
The device is equipped with a filament that breaks the CSF bubble’s surface tension and guides the fluid directly from the needle into the collection vial.
The device offers greater ease of use, especially with neonatal patients and children under three months of age, an age group which constitutes a significant percentage of those receiving the lumbar puncture procedure. In addition, the flexible filament allows for easy capping of the collection vial for storage of the fluid.
