  • Patent number: 5374276
    Abstract: An ear wax remover comprises an elongate rod having an extractor head on a first end and a swab attachment portion on a second end. The extractor head has a generally mushroom shaped tip and a pair of frusto-conical projections extending annularly around the rod adjacent the tip. Both the tip and the two projections have frusto-conical recesses therearound which diverge in the direction of the second end of the rod. The peripheries of the tip and projections, and the recesses therein define engagement surfaces for the extraction of ear wax. The swab attachment portion has recessed helical lines which crisscross to define a hatching pattern for the wrapping securement of a cotton swab. A medical section of the rod is of enlarged diameter for ease of handling.
