Claim 0:
1. A cell sample collection device, comprising:
an outer guide assembly, comprising:
a distal end with a rounded tip, the rounded tip having an aperture disposed therethrough, the aperture comprising a center opening and a plurality of cut-out segments; and

an inner guide assembly slidably received within the outer guide assembly, the inner guide assembly comprising:
a proximal end having a control handle; and
a distal end having a tip mount attached thereto, the tip mount having a frustoconical shape;
a collection support attached to the tip mount, the collection support comprising a plurality of arm members, each of the plurality of arm members fixedly coupled to a backside of a collection pad;
the collection pad secured to the collection support via a press fitting pin disposed through an opening in the collection support;

wherein the inner guide assembly is movable from a first position where the collection pad is collapsed inside the distal end of the outer guide assembly and isolated from an exterior of the outer guide assembly to prevent contamination of the collection pad during positioning of the cell sample collection device for collecting a cell sample from a cell sample surface, to a second position where the collection pad is pushed through the aperture in the rounded tip of the outer guide assembly and expands into a full shape of the collection pad to contact and collect the cell sample from the cell sample surface, and
wherein the outer guide assembly is configured to slide proximally along the inner guide assembly when the collection pad, in the second position, contacts the cell sample surface for providing feedback to a user indicating that the contact has been made.
