Abstract
A device for removing earwax from an ear canal includes a shaft; and an earwax collector head at an end of the shaft. The collector head is in the form of a helical strip surrounding a substantially elongated space. The helical strip has a cross section such that an outward facing surface of the helical strip is substantially flat and an interior surface of the helical strip radially tapers to an inward facing edge. A distal end of the helical strip tapers to present a wedge.
Claims17
A device for removing earwax from an ear canal, comprising:
- a shaft;
- an earwax collector head;
- and
- a flexible section between the earwax collector head and the shaft, wherein the earwax collector head is enclosed in a housing having an opening, wherein the housing is adapted to enable the earwax collector head to extend outwardly from the opening of the housing when the shaft is rotated;
- and
- wherein the earwax collector head includes a helical strip surrounding a substantially elongated space and ending with a strip distal end, wherein the strip distal end flattens to presents a blade-like end, allowing to amass said earwax into said space via said strip distal end, wherein the earwax collector head has a longitudinal axis, wherein the helical strip has an interior surface facing radially inward toward the longitudinal axis of the earwax collector head, wherein the interior surface of the helical strip tapers radially inwardly to a blade-like edge, wherein the blade-like edge removes at least a portion of the earwax from an ear canal when the shaft is rotated while the earwax collector head is inserted into the ear canal, and wherein the flexible section is designed to enable bending in all three dimensions and includes substantially rigid anchor segments separated by flexible segments.

A device for removing earwax from an ear canal, comprising:
- a shaft;
- and
- an earwax collector head including a helical strip surrounding a substantially elongated space and ending with a strip distal end, wherein the strip distal end flattens to present a blade-like end, the earwax collector head having a longitudinal axis, wherein the earwax collector head has an outer diameter along the longitudinal axis, wherein the outer diameter of the earwax collector head is adapted to vary along the longitudinal axis such that the outer diameter of the earwax collector head adjusts to a varying diameter of an ear canal when the earwax collector head is inserted into the ear canal, wherein the earwax collector head is connected to the shaft and enclosed in a housing having an opening configured to enable the earwax collector head to extend outward from the opening of the housing when the shaft is rotated, wherein the earwax is collected in the collector head when the earwax collector head is inserted into the ear canal and the shaft is rotated.
