Abstract

A disposable plastic device insertable into an ear canal that is used to scrape wax and debris from the ear canal without injuring the ear canal and ear drum when rotated inside the ear canal. The device is constructed using an elongated shaft which is adapted to be grasped and rotated. Accordingly, the preferred embodiment consists of a first plurality of blades attached to the first end of the elongated shaft having a curved concave clockwise shape. And a second plurality of blades attached to the second end of the elongated shaft having a curved convex clockwise shape in the opposite direction. The device has a dome tip at the shaft first end and the shaft second end that are tapered from the shaft first tip and shaft second tip respectively, to the midpoint of the blades.

Claims

1. A device for inserting into an ear canal that rotates inside said ear canal and scrapes an optimal amount of earwax and debris from said ear canal without injuring said ear canal and ear drum, said device comprising:

an elongated shaft having a first end and a second end and a longitudinal axis;

a first plurality of blades attached to said first end being uniformly radially spaced on said first end about the longitudinal axis, the first plurality of blades being connected to a shaft parallel to the longitudinal axis, said first plurality of blades connected to said shaft parallel to the longitudinal axis, each adjacent pair of said first plurality of blades having a first space that is adapted to collect and store earwax and debris;

said first plurality of blades are adapted to cut and scrape an optimal amount of earwax and debris from the surface of the ear canal;

wherein said first plurality of blades have a first curvature direction being concave clockwise from a base of said shaft parallel to the longitudinal axis with a first arc radian from 20 degrees to 50 degrees;

wherein said first plurality of blades each having a first concave and having a first acute edge angle ranging from 3 to 7 degrees adapted to cut and scrape said optimal amount of earwax and debris from the surface of the ear canal at a first angle ranging up to 45 degrees adapted to require less rotational force when rotated inside the ear canal;

a second plurality of blades attached to said second end being uniformly radially spaced on said second end about the longitudinal axis, the second plurality of blades being connected to the shaft parallel to the longitudinal axis, said second plurality of blades connected to said shaft parallel to the longitudinal axis, each adjacent pair of said second plurality of blades having a second space that is adapted to collect and store earwax and debris, said second plurality of blades are adapted to cut and scrape an optimal amount of earwax and debris from the surface of the ear canal;

wherein said second plurality of blades having a second curvature direction being convex clockwise from the base of the shaft parallel to the longitudinal axis with a second arc radian from 20 to 50 degrees; and

wherein said second plurality of blades having edges that are second convex and having a second acute edge angles ranging from 3 degrees and 7 degrees adapted to cut and scrape said optimal amount of earwax and debris from the surface of the ear canal at a second angle ranging up to 45 degrees adapted to require less rotational force when rotated inside the ear canal.

2. The device in accordance with claim 1:

wherein said device further comprises a tip at said shaft parallel to the longitudinal axis first end, said tip shaped like a dome, said tip adapted to protect said ear canal when said device is inserted and rotated in said ear canal.

3. The device in accordance with claim 1:

wherein said elongated shaft having a circular section of the device which is adapted to be grasped and rotated.

4. The device in accordance with claim 3:

wherein said device further comprises a tip at the second end of said shaft parallel to the longitudinal axis, wherein said tip shaped like a dome and adapted to protect said ear canal when said device is inserted and rotated in said ear canal.

5. The device in accordance with claim 3 further comprising:

said first plurality of blades having a bevel shape at the shaft first end that tapers from a first shaft tip to a midpoint of the first plurality of blades for minimizing the amount of earwax and debris being pushed inside ear canal upon insertion and adapted to reach earwax and debris located deeper inside the ear canal.

6. The device in accordance with claim 3 further comprising:

said second plurality of blades having a bevel shape at the shaft second end that tapers from a second shaft tip to a midpoint of the second plurality of blades for minimizing the amount of earwax and debris being pushed inside ear canal upon insertion and adapted to reach earwax and debris located deeper inside the ear canal.

7. The device in accordance with claim 1:

wherein said device is injection molded from plastic comprising one of polypropylene and polyethylene, or a combination thereof.
