Abstract

A cytology cell sampler for use in collecting mucosal cell samples from a human comprising a handle and a head portion. The handle is grasped by the operator and the head portion is then abutted a patient'"'"'s mucosal surface for sample collection. The head portion has a first plate and a plurality of secondary plates with the first plate attached to the handle opposite the end grasped by the operator. The first plate has a longitudinal axis generally along a longitudinal axis of the handle, and the plurality of secondary plates project from the first plate generally perpendicular to the longitudinal axis of the first plate. There is at least one collection space between the plurality of secondary plates. Each secondary plate has a shaped free edge for contacting the mucosal surface of the human, collecting a sample between the plurality of secondary plates by scraping the mucosal surface with the shaped free edges.

Claims

1. A mucosal sampler for use in collecting mucosal cell or tissue samples from a human, the mucosal sampler comprising:

a handle for grasping at a first end, having a longitudinal handle axis, and

a head portion having a first plate and a plurality of secondary plates, the first plate attached to the handle at a second end of the handle and having a longitudinal plate axis, and the plurality of secondary plates projecting from the first plate generally perpendicular to the longitudinal axis of the first plate, the plurality of secondary plates arranged substantially parallel to each other spaced side by side in a perpendicular plane with respect to the longitudinal axis, and having at least one collection space between the plurality of secondary plates, and each secondary plate having a shaped free edge for contacting the mucosal cells or tissue of the human, the cell or tissue sample being collected in the at least one space between the plurality of secondary plates.

2. The invention of claim 1 in which the handle and head portion comprise a polymer.

3. The invention of claim 2 in which the polymer comprises a polymer selected from a list of polymers consisting of:

elastomeric silicone, polyethylene, polypropylene, polyester, polyurethane, poly(vinyl chloride), polyisobutylene, polychloroprene, polybutadiene, and copolymers of this list.

4. The invention of claim 1 in which the handle and head portion comprise a metal.

5. The invention of claim 4 in which the metal comprises a metal selected from a list of metals consisting of:

iron, steel, stainless steel, chromium, tungsten, vanadium, molybdenum, nickel, aluminum, titanium, and alloys of metals of this list.

6. The invention of claim 3 in which the handle and the head portion are integral in construction.

7. The invention of claim 1 in which the handle and the head portion are constructed separately and joined together.

8. The invention of claim 7 in which the handle comprises a metal and the head portion comprises a polymer and the head is attachable to the handle.

9. The invention of claim 8 in which in which the polymer comprises a polymer selected from a list of polymers consisting of:

elastomeric silicone, polyethylene, polypropylene, polyester, polyurethane, poly(vinyl chloride), polyisobutylene, polychloroprene, polybutadiene, and copolymers of this list.

10. The invention of claim 8 in which the metal comprises a metal selected from a list of metals consisting of:

iron, steel, stainless steel, chromium, tungsten, vanadium, molybdenum, nickel, aluminum, titanium, and alloys of metals of this list.

11. The invention of claim 1 in which the longitudinal handle axis forms an obtuse angle with the longitudinal plate axis.

12. The invention of claim 11 in which the obtuse angle is from about 179°

to about 135°
