2. Description of the Prior Art Previous aural dressings known to the applicant consist of gauze attached to the patients head by gauze strips or by adhesive tape. This type of dressing is known as the firm mastoid dressing. To construct such a dressing, a hole is cut in the center ofa 4'' X 4" gauze pad. The gauze pad is then placed over the ear. The gauze pad is then attached to the patients head by wrapping gauze strips or adhesive tape around his head and the gauze pad. It can be clearly seen that such'a dressing would be time-consuming to apply and uncomfortable to wear.
SUMMARY OF THE INVENTION The present invention is directed towards overcoming the problems and disadvantages in previous aural dressings. The concept of the present invention is to provide an aural dressing comprising a flexible body consisting of an open cell foam material. The body includes a base portion for surrounding the patients ear ing which is adapted for many uses in a hospital or the like, as for example, following many types of mastoid surgeries, tympanoplasties and otoplasties. It meets the requirements of protecting the post aural wound and prevents the packing in the ear canal from falling out without the bulk of the old style aural dressingslt is quickly applied and is 'soft andcomfortable to wear. The open cell foam material allows the patient to hear through the aural dressing. Also, air can flow through the open cell foam material and keep the patients ear cool.

FIG. 5 is a sectional of FIG. 4.
DESCRIPTION OF THE PREFERRED EMBODIMENT The aural dressing ll of the present invention comprises in general a body 13 including a base portion 15 and flap means 17. The base portion 15 is'provided with an opening or slot19 for allowing the external ear view taken as on the line V--'V of a patient to extend therethrough. The opening 19 is preferably curved for closely surrounding the external ear. The body 13 is formed of a flexible porous material for permitting air to flow therethrough. The porous material is preferably an open cell material of the type known to those skilled in the art as reticulated polyu rethane foam. An open cell material found suitable for this purpose is that produced by the Foam Division of Scott Paper Co. of 1500 East Second Street, Chester, Pa., and known as Scott Industrial Foam. Preferably, the foam material used provides a soft and fine pore characteristic having approximately 84 pores per square inch as designated by Scott Paper Co.
In use, the base portion 15 surrounds the external ear of the patient and the fiap means 17 folds over the base portion 15 and covers the external ear, thus protecting the post aural wound and preventing the packing in the ear canal from falling out. The flap means 17 preferably includes a first flap portion 21 and a second flap portion 23. The first and second flap portions 21, 23
are disposed on either side of the base portion 15. Flexible joints 25 are provided between the first and second flap portions 21, 23 and base portion 15. Preferably, the flexible joints 25 are made by an impulse sealing operation performed by a well known method on the foam material of the-body 13 between the base portion 15 and the first and second flap portions 21, 23. In other words, the base portion 15 and the first and second flap portions 21, 23are formed integrally of one piece of foammaterial. The foam material is heated on one side along a pair of lines between the base portion 15 and the first and second flap portions 21, 23, thereby making a pair of creases along the joints 25. Excess foam material is then clipped away from the joints 25. The first and second flap portions 21, 23 will then lie substantially flat against the base portion 15 when folded thereover.
The base portion 15 preferably includes an adhesive means 27 adjacent the opening 19 for attaching the body 13 to a portion of the patients head surrounding his external ear. The adhesive means 27 consists of an adhesive portion 29and'a protective cover portion 31.
'The adhesive portion 29 consists of a double face medical tape having one face attached to the base portion 15 and having the other face attached to the protective cover portion 31. When the aural dressing 11 is applied to a patients head, the cover portion 31 is removed from the adhesive portion 29 and the adhesive portion 29 is attached to a portion of the patients head surrounding his external ear. Preferably, the adhesive means 27 is spaced away from one side of the opening 19 to provide an open area 33. This open area 33 preventsdamage to the sutures located behind the patients ear after mastoid surgery.
The first flap portion 21 includes an adhesive means 35 positioned so that when the first and second flap portions 19, 21 are folded over the base portion 15, the adhesive means 35 attaches to the second flap portion 23 where it overlaps the first flap portion 21. The adhesive means 35 includes an adhesive portion 37 and a protective cover portion 39. The adhesive portion 37 consistsof a double faced medical tape having one face attached to the first flap portion 21 and having the other face attached to the protective cover portion 39. When the aural dressing 11 is attached to a patients head, the'first flap portion 21 is folded over the base portion 15 and the protective cover portion 39 is removed. Next, the second flap portion 23 is folded over the base portion 15 and overlaps the adhesive portion 37 of the first flap portion 21 and is attached thereto.
In using the aural dressing 11 of the present inven tion, the first step is to removethe protective cover portion 31 from the adhesive means 27, as heretofore described. Next, the aural dressing 11 is positioned on the patients head H in an open position as shown in FIG. 3. The patients external ear E is pulled through I the opening 19 and the aural dressing 11 is secured to the patients head H by means of the adhesive portion 29. Next, the first flap portion 21 is folded over the base portion 15 and the patients external ear E. The protective cover portion 39 is removed from the adhesive means 35 and the second flap portion 23 is folded over the base portion 15 and the patients external ear E and is attached to the adhesive portion 37 of the first flap portion 21 so that the aural dressing 11 is in the closed position as shown in FIGS. 4 and 5.
It should be noted that the aural dressing 11 is designed in such a way that it may be used on either the right or left ear of the patient. When in the closed position, the aural dressing 11 takes on a rounded form to appear as least conspicuous as possible. For the same reason, the aural dressing 1] is preferably constructed of a foam material that is flesh colored.
it should be noted that when the term external ear is used in the specification, it is deemedto comprise, in general, the helix, the antihelix, the fossa of the antihelix, the antitragus, the tragus, and the lobe.
Although the invention has been described and illustrated'with respect to a preferred embodiment thereof, it is not to be so limited since changes and modifications may be made therein which are within the full intended scope of the invention.
