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.

Claims (15)

1. A method for removing earwax from an ear canal, the method comprising:

inserting into the ear canal an earwax collector head that is connected to a shaft, wherein the earwax collector head has a longitudinal axis, wherein the earwax collector head includes a helical strip surrounding a substantially elongated space and ends with a strip distal end, 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;

rotating the shaft to collect the earwax from the ear canal into the collector head, wherein the blade-like edge removes at least a portion of the earwax from the ear canal when the shaft is rotated while the earwax collector head is inserted into the ear canal; and

removing the collector head from the ear canal.

2. The method of claim 1 , wherein inserting the earwax collector head into the ear canal further comprises placing a head opening of a housing that initially encloses the collector head on an exterior opening of the ear canal, and rotating a knob to rotate the shaft to extend the collector head out of the head opening and into the ear canal and to collect the earwax into the collector head.

3. The method of claim 1 , further comprising,

introducing a cerumen dissolution agent into the ear canal.

4. The method of claim 3 , wherein introducing a cerumen dissolution agent into the ear canal further comprises:

connecting a body that initially encloses the collector head to a source of the cerumen dissolution agent.

5. The method of claim 3 , wherein the cerumen dissolution agent is introduced into the ear canal 1 minute to 20 minutes before inserting the collector head into the ear canal.

6. The method of claim 1 , wherein the helical strip has a cross section such that an outward facing surface of the helical strip, facing away from the elongated space, is substantially flat.

7. The method of claim 1 , wherein the strip distal end tapers to present a wedge.

8. The method of claim 1 , wherein the earwax collector head has a local diameter, wherein the step of inserting the earwax collector head into the ear is performed such that the local diameter of the earwax collector head, along a length of the connector head, adapts automatically to match and fill a varying diameter of the ear canal.

9. A method for removing earwax from an ear canal, the method comprising: inserting into the ear canal an earwax collector head that is connected to a shaft, wherein the earwax collector head includes a helical strip surrounding a substantially elongated space and ending with a strip distal end, wherein inserting the earwax collector head into the ear canal further comprises placing a head opening of a housing that initially encloses the collector head on an exterior opening of the ear canal, and rotating a knob to rotate the shaft to extend the collector head out of the head opening and into the ear canal and to collect the earwax into the collector head; rotating the shaft to collect the earwax from the ear canal into the collector head; and removing the collector head from the ear canal.

10. A method for removing earwax from an ear canal, the method comprising: inserting into the ear canal an earwax collector head that is connected to a shaft, wherein the earwax collector head includes a helical strip surrounding a substantially elongated space and ending with a strip distal end; introducing a cerumen dissolution agent into the ear canal, wherein introducing a cerumen dissolution agent into the ear canal further comprises connecting a body that initially encloses the collector head to a source of the cerumen dissolution agent; rotating the shaft to collect the earwax from the ear canal into the collector head; and removing the collector head from the ear canal.
