ABSTRACT:
An elongated plastic sample collector probe for cell sampling, particularly including mucosal cells. The probe has a generally rigid rearward handle portion, a forwardly narrowing tapered shank portion, and a small sample collector cup at the forward tip of the shank portion. The plastic material of which the probe is made has the physical characteristics of flexibility and elasticity, and these characteristics cooperate with the forwardly narrowing taper to provide the probe with a progressively increasing transverse flexibility toward the collector cup. Such flexibility, together with the configuration and orientation of the cup relative to the shank portion, facilitates cell sample collection through use of a light, whisking stroke, which minimizes the likelihood of injury to sensitive tissues. In one form of the invention the probe is made of a light-conducting plastic material and a rearward part of the probe is coupled with an illuminating unit for transmission of light forwardly through the shank portion to the sample collecting cup at the forward tip so as to illuminate the cup and the sample collecting region.
