Abstract
A transcranial Doppler (TCD) probe fixation assembly is provided comprising an assembly for holding a TCD probe. The probe holding assembly comprises in one embodiment a track assembly and in another embodiment a single bar assembly. The ends of both the track assembly and bar assembly are connected to an annular member. Strap retaining members are provided on the exterior of the annular member for strapping the TCD probe to a patient's head. In use, the position of the probe is selected by moving the probe linearly along the track and bar assemblies and by rotating the track and bar assemblies relative to the annular member. Thereafter, the probe is angulated until a desired signal is obtained, at which point it is locked in place.
