摘要： Embodiments for a cerebrospinal fluid flow detector for detecting the flow of cerebrospinal fluid are disclosed. In some embodiments, the cerebrospinal fluid flow detector includes a casing with a rotatable wheel having a plurality of radially extending arms disposed therein. The rotatable wheel is in communication with a channel having a distal end in communication with an inlet port and a proximal end in communication with an outlet port such that the flow of cerebrospinal fluid through the channel causes the rotatable wheel to rotate. In some embodiments, each radially extending arm includes at least one radiopaque marker in which movement of the rotatable wheel caused by fluid flow through the channel allows an X-ray imaging apparatus to detect the difference in position of a respective radiopaque marker at multiple times caused by rotation of the rotatable wheel.
