Abstract

The stick swab has one or more compliant heads adapted for cleaning body orifices such as ear canals. The head or heads are formed with a contoured outer surface to aid in gripping and removing material or debris from the body orifices. The contours preferably take the form of a helical augur whereby material will be withdrawn from the orifice merely by appropriately rotating the swab about its axis.

Claims

1. A stick swab for cleaning bodily orifices such as the ear, and comprising:

a stick portion;

means forming elongated swab heads on each end of said stick portion, one of said swab heads having an enlarged helical ribe with a left hand spiral, and the other of said swab heads having an enlarged helical rib with a right hand spiral when said stick swab is viewed in elevation; and

means visible on said stick portion for indicating a direction for rotating said stick swab about its axis, which direction will cause both of said swab head ribs to augur material out of the orifice when said swab heads are inserted into the orifice.

4. The stick swab of claim 1 wherein said swab heads are formed from a fibrous material which is impregnated with an additive which renders the fibers selectively hardenable at said ribs.

5. The stick swab of claim 4 wherein said additive is starch.

6. The stick swab of claim 1 wherein there are helixes formed on end portions of said stick portion, and said swab heads are formed from pliant material overlying said helixes with said pliant material bieng of substantially constant thickness over said helixes whereby said pliant material assumes the configuration of said helixes to form said helical ribs.

7. The stick swab of claim 1 wherein said helical ribs are formed from a filament helically wound about said swab heads.

2. The stick swab of claim 2 wherein said swab heads are formed from an artificial material, and said ribs are formed by locally altering the hardness of said artificial material so that the ribs are harder than the remainder of the swab heads.

3. The stick swab of claim 2 wherein said artificial material is urethane polymer.
