<p>MULTIPLE SMEAR BRUSH A smear brush for obtaining cellular samples from a body cavity. The instrument has a rigid stem with a handle at one end, the other end having an integral brush with a flexible spine and fine flexible bristles. A flat blade at the root of the spines serves as a locator and stop at the entrance to a body cavity, while the flexible brush penetrates the cavity and follows any curvature of the cavity. When the instrument is rotated, the brush accumulates sample material from substantially the entire inner wall of the cavity, the brush being subsequently wiped across a slide to deposit the sample for examination.</p> |
