Lumbar puncture needle

Using a lumbar puncture needle to puncture the subretinal space of the lumbar spinal cord is an important clinical auxiliary examination method in neurology. It can be used to measure brain pressure, collect cerebral effusion for routine, biochemical and bacteriological examination, tumor cell and enzymatic examination, and provide evidence for the diagnosis of intracranial inflammation, tumor, hemorrhage and white matter demyelinating diseases. However, when the cranial pressure is too high, lumbar puncture should be cautious, it is best not to drain the fluid, only use the cerebrospinal fluid in the rubber tube of the brain pressure gauge to do the test, so as to avoid brain herniation. Contrast agents can also be injected into the subarachnoid space for downward or upward contrast. Air (or oxygen) can also be injected into the subarachnoid space and flowed into the skull in a directional direction for intraspinal lesion imaging, ventricle pneumoencephalography and cisternography.
