External ear cleaning device
| Details |
Inventors: Stevens, Robert B.;
Assignee:
Primary Examiner: Ostrager; Allen M.
Assistant Examiner:
Attorney, Agent or Firm: Hurt, Richardson, Garner, Todd & Cadenhead
An external ear cleaning device which is specially adapted for reaching the surfaces of the curved portions of the external ear. A substantially inflexible shaft has attached thereon at least one end piece constructed of a flexible material capable of absorbing water. The flexible material is deformable when pressure is applied to the shaft, such that the end piece can contact normally inaccessible portions of the external ear. The end piece also has a portion which extends radially outward from the shaft and which prevents harmful insertion of the device into the ear opening. |

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS.
1A and 1B illustrate one embodiment of the invention, which is generally indicated by the number 10.
The device 10 comprises a substantially inflexible shaft 12 having at each end 14 a moisture absorbent end piece 16.
The device 10 is preferably constructed of a single piece moisture absorbent material which can be cut from a block of the material or molded, using well known techniques.
The end pieces preferably have a cleaning agent, such as soap, incorporated therein.
Suitable materials for the device 10 include the various synthetic sponges made from polymers such as polyester.
In general, materials suitable for use in the device 10 are those having the ability to absorb moisture to an extent sufficient to wet the cleaning agent contained in the material.
The shaft is treated with a stiffening agent so that it does not bend substantially upon application of pressure applied by the user in cleaning of the ear.
In addition, the shaft is preferably waterproofed.
The waterproofing and stiffening can be provided by a chemical such as HiLoft 6279, manufactured by National Starch and Chemical Corporation.
This chemical is a self reactive, vinyl acetate terpolymer emulsion.
In contrast to the shaft, the end pieces 16 are left untreated with the stiffening agent, and thus, especially upon wetting, are relatively flexible.
The shape of the end piece is important from the standpoint of reaching all of the surfaces formed by the curved portions of the external ear.
Again with reference to FIG.
1A, the moisture absorbent end pieces 16 comprise a first portion 18 which is attached to the end 14 of the shaft 12.
Secured on top of the first portion 18 is a second portion 20 which can comprise a first cylindrical section 22 and a second cylindrical section 24.
The circumference of each cylindrical section 22 and 24 is less than that of the first portion 18, with section 24 having a smaller circumference than section 22.
By providing progressively smaller circumferences for the two cylindrical sections 22 and 24, insertion of the end piece 16 into the curved portions of the external ear is facilitated
