Abstract

A cerumen removal apparatus for removing cerumen from an ear canal. The apparatus includes a body having a distal end and a proximal end interconnected by a main longitudinal axis; said distal end including a hollow collector head having at least one spiral vane or ridge projecting radially inward from an inner surface thereof and enclosing a lumen ending with an opening opened to said lumen for amassing said cerumen in said lumen via said opening; wherein said at least one spiral vane or ridge is adapted to guide the cerumen in a proximal direction into said hollow collector head when said hollow collector head rotates in the ear canal.

Claims (16)

1. A cerumen removal apparatus configured to remove cerumen from an ear canal, comprising:

a collector head having at least one spiral vane or ridge projecting radially inward from an inner surface thereof and enclosing a lumen ending with an opening opened to said lumen for amassing said cerumen in said lumen via said opening, wherein said at least one spiral vane or ridge is configured to guide the cerumen in a proximal direction into said collector head when said collector head rotates in said ear canal; and

a device body configured to accommodate said collector head, said device body including at least one rotating mechanism configured to rotatably extend said collector head out from said device body and further into said ear canal; wherein rotation of said collector head causes said collector head to amass said cerumen and to remove said cerumen from said ear canal.

2. A cerumen removal apparatus configured to remove cerumen from an ear canal, comprising:

a collector head having at least one spiral vane or ridge projecting radially inward from an inner surface thereof and enclosing a lumen ending with an opening opened to said lumen for amassing said cerumen in said lumen via said opening, wherein said at least one spiral vane or ridge is configured to guide the cerumen in a proximal direction into said collector head when said collector head rotates in the ear canal; and

a device body configured to accommodate said collector head, said device body including at least one rotating mechanism including a knob, wherein said knob rotatably-extends said collector head out from said device body and further into said ear canal; wherein rotation of said collector head causes said collector head to amass said cerumen and to remove said cerumen from said ear canal.

3. The apparatus of claim 2 , wherein said collector head is deformable, wherein said deformable collector head is configured to fit a size and a shape of said ear canal when said collector head is inserted into said ear canal.

4. The apparatus of claim 3 , wherein at least a portion of said collector head has a cross sectional diameter that fits the diameter of the ear canal to allow rotation of said collector head within said ear canal.

5. The apparatus of claim 2 , wherein said collector head has a scoop-like or a shovel-like structure.

6. The apparatus of claim 2 , wherein the height of the vanes or ridges varies such that it is increased toward the proximal end of the collector head.

7. The apparatus of claim 2 , wherein the rotating mechanism comprises a decoupling mechanism such that after the collector head has been extended out of the device body by a predetermined distance of no more than 1 cm, further rotation of the knob produces no further extension of the collector head.

8. The apparatus of claim 2 , wherein said shaft is configured to change shape so as to follow a tortuosity of said ear canal via at least one of: deformation, bending, twisting, and rotation.

9. The apparatus of claim 2 , wherein said hollow collector head is configured to collapse under a predetermined pressure, said predetermined pressure being less than a pressure required to push the cerumen in the ear canal.

10. The apparatus of claim 2 , further comprising at least one reservoir in fluid communication with said hollow collector head, said reservoir containing cerumen softening liquid and being configured to dispense said cerumen softening liquid within said ear canal.

11. The apparatus of claim 2 , wherein at least a portion of said hollow collector head comprises an elastic spring-like material configured to apply radial forces that press said portion against the walls of said ear canal.

12. The apparatus of claim 2 , wherein said at least one spiral vane or ridge ends at said distal end.
