  • FIGS. 1 through 24 illustrate embodiments of earwax removal devices and methods for removing earwax.
  • An earwax removal device 10 generally comprises a shaft 20 having a longitudinal axis and an earwax-extracting member 30 .
  • the earwax-extracting member 30 and shaft 20 can be separate and removably connected, or can be made as one integrated structure.
  • the two-piece configuration can include elements that screw together via a thread-fit, friction fit, snap-fit or any other suitable type of attachment. This configuration also allows one to choose which embodiment of the earwax-extracting member 30 to use based on the desired earwax removal capabilities such that the earwax-extracting members 30 are interchangeable.
  • the components of the device 10 may be made of plastic, rubber, metal, or another suitable material as required for desired control and flexion. Additionally, the device 10 can be comprised of a single, solid material or can have a core material with an outer shell, e.g. a wire covered by a molded plastic that has the appropriate structure. The device 10 and its components are intended to be either disposable or reusable. The device 10 can also be made of a material suitable for various methods of sterilization, including irradiation.
  • the shaft 20 may be of varying lengths and widths.
  • the shaft 20 can be manually rotated by the user or can incorporate a motor-driven shaft 20 that provides rotation.
  • a typical length range can be two to three inches, but longer or shorter lengths may be utilized depending on the desired amount of control.
  • the width of the shaft 20 can be similar to that of the ear canal, about six to seven millimeters, particularly when the shaft 20 and earwax-extracting member 30 form a single structure.
  • the shaft 20 can also include gripping surface 24 , such as a flange design, etching, spiral ridging or a coarse surface, to improve handling.
  • the shaft 20 can also include a handle 26 in any suitable form for improved gripping.
  • each embodiment of the present invention may have several common properties. Unless otherwise specified, each embodiment can include a conical surface configuration or conical configuration of members at the tip portion 50 of the device 10 to meet flush with the tympanic membrane. Each device 10 can have a soft widening of the body portion 40 or increase in the height of the active surface members, which create a gradual widening of the wax removal tip as the external auditory canal widens. Further, each device 10 can include an opening 54 in the tip portion 50 that leads to a channel through which wax is actively driven or channeled by the pressure of device 10 insertion and rotation.
  • the body portion 40 of the earwax-extracting member 30 can include an exit hole 49 to exhaust wax under pressure in the device body closer to the tip.
  • the device 10 can be comprised of a flexible material such that the body of the earwax-extracting member 30 can compress and expand to dislodge engaged wax.
  • a softer material such as soft plastic or rubber, can allow for a tight fit of the earwax-extracting member 30 against the ear canal skin, thereby enhancing functionality.
  • Ear wax removing tips with soft core or compressible design will self-guide through the external auditory canal tortuosities and compress to minimize the risk of damage during blind insertion.
  • the earwax-extracting members 30 that anatomically fit the external auditory canal can remove the wax bolus as a single collection.
  • the typical human ear canal is about five to six millimeters across in the bony portion near the tympanic membrane and about eight to ten millimeters wide ear the lateral, cartilaginous region.
  • the canal length about two to three centimeters long, defines the maximum depth of penetration of the earwax-extracting member 30 .
  • Various widths permit the device 10 to adapt to individual variations in the human ear canal.
  • Anatomically correct wax removal devices better conform to an ear canal to ensure that the surface contacts are flush with the skin and eardrum to avoid damage that may occur when small tools are inserted blindly in uncontrolled directions. Also, the canal-fitted tools can more effectively remove the wax in bulk. Other configurations can be determined for appropriate animals.
  • each device 10 can have internal safety guards to control the depth at which the device 10 is inserted in the ear canal.
  • each device 10 can include a guard member 70 , such as a ring or coil, or another suitable sharp local flaring at about five to seven millimeters from the tip portion 50 or end of the earwax-extracting member 30 .
  • the guard member 70 is intended to limit the extent of tip penetration at the narrowing of the canal known as the “bony-cartilaginous junction.”
  • Additional rings or flares along the earwax-extracting member's body can be included to control the width of the body and limit penetration in the ear from the conchal bowl region into the external auditory canal itself. They can be used to adjust the exposure of the functional elements, such as bristles 45 , to the canal skin surface.
  • Such embodiments can comprise three extension members distributed about the body portion 40 and tip portion 50 of the device 10 . A first extension member is located along the perimeter of the tip portion 50 , a second extension member is located at the junction of the upper section 41 and lower section 43 of the body portion 40 , and a third extension member is located at an end of the wax extracting member 30 closest to the shaft 20 of the device 10 .
  • the extension members may be in the shape of solid rings or coils and can be used to control the depth to which the earwax-extracting member 30 can be inserted in the ear canal. Section dividing rings or coils can enhance device 10 rotation through canal curvatures.
  • the earwax-extracting member 30 may have variations in dimensions and configurations.
  • a straight, wide cylindrical design can contact the ear canal walls more evenly and draw in softer wax as it rotates.
  • a conical design that tapers toward the tip may bore into a harder wax plug, intending to engage the plug and extract it entirely.
  • a narrow cylindrical design may bore smaller holes into a large solid wax accumulation, which may facilitate removal with a second extraction technique. All surfaces of the earwax-extracting members 30 can be textured or etched to increase hold of the wax onto the device 10 .
  • a wide base, with or without a narrower tip segment, is a safety control that can limit penetration of the wax removing tip.
  • the earwax-extracting member 30 may vary in sharpness and hardness. Soft wax would be safely and effectively removed with soft outer edges whereas harder wax may warrant sharper, blade-like edges that cut into the wax.
  • the earwax-extracting member 30 may terminate with or without a tip such that it can have a flat end or have a gentle, conical rise that can engage wax near the tip. The conical design may come to a point or have a blunt end.
  • a flat, umbrella-style cover may be added to the end of the earwax-extracting member 30 to minimize the risk of damage to the eardrum.
  • the umbrella-style cover may have an added coating or surface material, such as foam or cotton to further prevent potential damage to the eardrum.
  • the ear-extracting member in all embodiments can be made of a soft, malleable plastic, rubber, or other suitable material to conform to the anatomical shape of the ear canal.
  • All embodiments of the earwax-extracting member 30 can flex and can be compressible in a direction along the longitudinal axis of the shaft 20 of the device 10 .
  • the range of compressibility is approximately one millimeter to four millimeters.
  • Embodiments using firmer plastics generally compress when coil or spring segments are utilized.
  • Embodiments using softer materials can vary in the amount of compressibility, depending on the structure of the earwax-extracting member 30 .
  • the various compressible and extension structures of the earwax-extracting member 30 effectively engage and dislodge wax while minimizing the risk of damage that can be caused by overly forceful insertions.
  • the earwax-extracting member 30 can have a hollow core to admit and collect wax, as well as an opening 54 at the tip portion 50 , to core into impacted wax.
  • the openings in the earwax-extracting member 30 can lead to at least one channel within the body to effectively collect wax, steer the wax laterally out of the canal, and actively prevent impaction of wax.
  • the body portion 40 may be comprised of a harder material to scrape out harder wax in the ear canal.
  • the hollow interior may be filled with a wire mesh that aids in grating wax, or a cutting blade(s) to cut canal hair.
  • the “club” embodiment of the device 10 comprises an earwax-extracting member 30 having an irregular surface with a bump and trough pattern. Some troughs may open into an optional wax channel(s) through the earwax-extracting member 30 .
  • An optional central channel network may steer compressed wax laterally through the device 10 .
  • the embodiment can be made in a soft material that could allow “sponging” of wax into its center.
  • the earwax removal device 10 comprises a shaft 20 having a longitudinal axis and an earwax-extracting member 30 .
  • the earwax-extracting member 30 can have a length in a range of between about ten to twelve millimeters.
  • the earwax-extracting member 30 has a body portion 40 having a first end 42 and a second end 44 , the first end 42 and the second end 44 of the body portion 40 located opposite each other.
  • the earwax-extracting member 30 also has a tip portion 50 located at the first end 42 of the body portion 40 .
  • the shaft 20 is connected to the second end 44 of the body portion 40 .
  • FIG. 2 illustrates that the protrusions 46 of the body portion 40 and the recesses 48 of the body portion 40 can be arranged alternately and can be curved or substantially round in shape. Also, as shown in FIG. 1 , the multiple protrusions 46 of the body portion 40 can vary in size, a first group of protrusions 46 A being smaller in size than a second group of protrusions 46 B. The differently sized protrusions 46 can create an irregular or irregularly, irregular surface. The protrusions 46 can also be coupled with troughs or deep-set entrances into a tunnel 60 that is formed inside the earwax-extracting member 30 .
  • the widths of the body portion 40 at two different distances from the second end 44 of the body portion 40 are different from each other.
  • the varying widths allow the device 10 to better fit within the ear canal.
  • the body portion 40 can be divided among an upper section 41 and a lower section 43 .

  • a guard member 70 such as a ring or other suitable extending structure, can surround the body portion 40 at the second end 44 of the body portion 40 .
  • a safety mechanism can be used at three junctions of the ear-extracting member.
  • a safety mechanism can include three extension members, a first extension member 32 surrounding the perimeter of the tip portion 50 , a second extension member 34 surrounding the perimeter of the body portion 40 and located between the upper section 41 and the lower section 43 , and a third extension member 36 surrounding the perimeter of the body portion 40 and located proximate to the second end 44 of the body portion 40 .
  • the first through third extension member can increase in size to anatomically correspond with the ear.
  • the earwax-extracting member 30 can include a channel therethrough.
  • an opening 54 is formed in the tip portion 50 where wax can enter the device 10 into a tunnel 60 that is formed inside the earwax-extracting member 30 .
