Abstract

An ear speculum that includes a body having an ear-contacting tip with an opening; a light providing member; a viewing member; and a vacuum intake port, wherein the members and intake port are provided within the ear speculum with the vacuum intake port occupying a larger portion of the of the cross-sectional area of the ear speculum opening than the light providing or viewing members to facilitate removal of material from an ear canal. Also, an otoscope that includes a head; an ear speculum as described herein in operative association with the head; an image detector in image communication with the viewing member; a suction source in vacuum communication with the vacuum intake port; and a light source in illumination communication with the light providing member. Also, a system and method for removing material or debris from an ear canal using the otoscope described herein.

Claims

1. An ear speculum comprising:

a body having an ear-contacting tip;

a light providing member;

a viewing member; and

a vacuum intake port,

wherein the light providing member, viewing member and vacuum intake port extend within and through the ear-contacting tip and the ear-contacting tip is configured and dimensioned with a cross-sectional area that provides sufficient space therein for the light providing member and viewing member and the intake port, the viewing member provided in a peripheral edge of the ear-contacting tip, and with the vacuum intake port occupying at least 50% of the cross-sectional area of the ear-contacting tip to facilitate removal of material from an ear canal.

2. The ear speculum of claim 1, wherein:

the light providing member comprises optical fibers; and

the viewing member comprises a lens.

3. An otoscope comprising:

a head;

an ear speculum of claim 1 in operative association with the head;

an image detector in image communication with the viewing member;

a suction source in vacuum communication with the vacuum intake port; and

a light source in illumination communication with the light providing member.

4. The otoscope of claim 3, which further comprises:

a collection chamber in vacuum communication with both the suction source and vacuum intake port, wherein the vacuum intake port is in vacuum communication with the suction source through the collection chamber.

5. The otoscope of claim 4, wherein the head is configured and dimensioned to house the suction source and collection chamber.

6. The otoscope of claim 4, wherein the collection chamber is configured and dimensioned such that material suctioned through the vacuum intake port from an ear becomes trapped within the collection chamber before reaching the vacuum source.

7. The otoscope of claim 3, which further comprises:

a display for presenting an image obtained by the viewing member;

optical components for adjusting the image obtained by the viewing member; and

a power source operatively connected to the suction source, light source, image detector and display.

8. The otoscope of claim 7, which further comprises controls for adjusting the suction source, light source, optical components and display.

9. The otoscope of claim 7, which further comprises a base in communication with the head, wherein the base is configured and dimensioned to house the suction source, the display and the power source, and the suction source is in vacuum communication with the vacuum intake port through a collection chamber located in the speculum.

10. The otoscope of claim 7, wherein the optical components include a wide angle lens or a zoom lens.

11. The otoscope of claim 3, wherein the viewing member and light providing member are arranged adjacent each other around a peripheral edge of the ear-contacting tip.

12. The otoscope of claim 3, wherein the light providing member includes optical fibers that are arranged concentrically within the peripheral edge of the ear-contacting tip, and the vacuum port occupies at least 70% of the cross-sectional area of the ear-contacting tip.

13. A system for removing material from an ear canal, comprising:

an otoscope having a head;

an ear speculum having a proximal end in operative association with the head, and a distal end having an ear-contacting tip;

a vacuum intake port within the ear-contacting tip;

a suction source in vacuum communication with the vacuum intake port, wherein the suction is sufficient to remove any observed material from the ear canal;

a light providing member within the ear-contacting tip;

a viewing member within the ear-contacting tip;

a collection chamber in vacuum communication with both the suction source and vacuum intake port, wherein the vacuum intake port is in vacuum communication with the suction source through the collection chamber;

a light source in illumination communication with the light providing member;

optics that can obtain and transfer an image of the ear canal to a camera;

a base in communication with the otoscope;

a display within the base that presents the image obtained by the camera;

a power source within the base electrically connected to the suction source, light source and display; and

,

controls for adjusting the suction, illumination and display,

wherein the light providing member, viewing member and vacuum intake port extend within and through the ear-contacting tip and the ear-contacting tip is configured and dimensioned with a cross-sectional area that provides sufficient space therein for the light providing member and viewing member and the intake port, the viewing member provided in a peripheral edge of the ear-contacting tip-opening, and with the vacuum intake port occupying at least 50% of the cross-sectional area of the ear-contacting tip to facilitate removal of material from an ear canal into the collection chamber.

14. An ear-wax removal device comprising:

a body having an ear-contacting tip;

a light providing member;

a viewing member; and

a vacuum intake port provided within the ear-contacting tip opening and occupying at least 50% of a cross-sectional area of the ear-contacting tip;

wherein the light providing member, viewing member and vacuum intake port extend within and through the ear-contacting tip and the ear-contacting tip is configured and dimensioned with a cross-sectional area that provides sufficient space therein for the light providing member and viewing member and the vacuum intake port; and

the viewing member provided in a peripheral edge of the ear-contacting tip opening.

15. The device of claim 14, wherein the body is a pistol-shaped body having pistol grip that can be comfortably held by an operator of the device.

16. The device of claim 14 further comprising a suction source in vacuum communication with the vacuum intake port.

17. The device of claim 14, wherein the light providing member includes optical fibers that are arranged concentrically within the peripheral edge of the ear-contacting tip.
