ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to intestinal discharge control products and, more specifically, to flatulence deodorizers. There are various devices in this field for dealing with the problems of intestinal discharges with some degree of success. However, all of them are somewhat cumbersome and/or bulky to use. The present invention, the Flatulence Deodorizer, is the first product for this application to use activated charcoal cloth as a deodorizer because it is so much more effective in removing odor than other known agents and because of its highly efficient filtering action, the thickness of the cloth can be significantly reduced without loosing effectiveness. The filter is worn taped to the inside of briefs or panties and because of its slim profile, the wearer is comfortable and virtually unaware of its presence. The activated charcoal cloth filter is also washable and reusable. This makes the present invention the most effective, cost efficient, comfortable and least intrusive means of deodorizing gassy discharges.
2. Description of the Prior Art
There are other protective devices designed for shielding against, filtering and/or capturing intestinal exudations of various kinds. Typical of these is U.S. Pat. No. 4,182,335 issued to C. James Matrullo on Jan. 8, 1980.
Another patent was issued to Randolph E. Campbell on Dec. 25, 1984 as U.S. Pat. No. 4,490,145. Yet another U.S. Pat. No. 4,880,417 was issued to Alexander A. Yabrov on Nov. 14, 1989 and still yet another was issued on Nov. 1, 1994 to David W. Revelle as U.S. Pat. No. 5,360,421.
Another patent was issued to Kenneth J Grosse on Sep. 9, 1997 as U.S. Pat. No. 5,665,081. Yet another U.S. Pat. No. 5,728,080 was issued to Masuhiro Suyama on Mar. 17, 1998. Another was issued to Barbara Oakley Sauer on Sep. 28, 1999 as U.S. Pat. No. 5,957,907.

Issued: Jan. 8, 1980
An anal filter for protecting underwear from soiling, is attached to a person's anus solely be non-adhesive adherence to the anus and adjacent portions of the buttocks, due to a facing of fluffy fibrous material, and when attached, serves as a filter by being pervious to the discharge of gas through the anus but substantially impervious to complete passage of excreta carried by the gas or remaining on the anus from a bowel movement. A layer may be adhesively secured to the fibrous material and which prior to use of the anal filter can be pulled off from the fibrous material while pulling this material's fibers outwardly so as to give the material its fluffy characteristic.

An ostomy pouch having a filter element affixed to the outer pouch wall. The outer pouch wall has an aperture and the filter element includes a polymeric film cover and an insert of gas deodorizing material. The film cover also has an aperture and opposite ends of the insert overlie the two apertures.

Inventor: Alexander A. Yabrov
Issued: Nov. 14, 1989
An anal pad for preventing soiling of underwear due to undesired anal discharge. The anal pad includes a thin outer shell enclosing a semi-rigid shell. The semi-rigid shell may be a layer on one interior surface of the outer shell and may also partially cover the opposite interior surface of the outer shell. An absorbing layer is located within the outer shell and the semi-rigid layer. The absorbing layer contains glycerin which absorbs hydrogen sulfide gas and the combination of the absorbing layer and the semi-rigid shell acts as a sound muffling camera so as to decrease the noise due to flatus. The absorbing layer is made of a light porous materials, the semi-rigid layer is made of compressed paper and the outer shell is made of a thin sheet of lignin paper. A layer of glue is provided on the outer surface of the anal pad for attaching it to a user's underwear.

Inventor: David W. Revelle
Issued: Nov. 1, 1994
A washable and reusable absorbent garment designed to be fitted about the waist and legs and covering the groin and anal areas of a wearer. The garment includes a number of superimposed layers of textile material sewn together along their edges. Elastic material may be sewn in the material around the leg openings and waist to improve the fit. A liner material covers the inner surface of the garment. The liner layer of the garment or that portion which is next to the wearer's skin is a knitted bicomponent textile comprised of a brushed polyester outer layer which is interknitted with a nylon block co-polymer inner layer. The materials function to transfer moisture in both vapor and liquid form from the polyester side to the nylon side where it is dispersed and made available to the garment's second or absorbent layer. The two specific materials in the liner adjacent the wearer's skin and absorbent material work together to maintain a high degree of comfort for the wearer even after it has been wetted. The structural and functional integrity of the garment is maintained after repeated washings.

A pad for attenuating sound and absorbing odors from an anal region of an individual. The inventive device includes a pad member containing a volume of odor-absorbing granulated charcoal covered by a layer of filler material and encapsulated with a flexible web. A gluteus insert extends from the pad for positioning between the gluteus-maximus muscles and against the anal region of the user to attenuate noise emanating therefrom.

The present invention relates to a degassing device for an artificial anal bag which is capable of storing the gas generated in the intestines, and of discharging the gas from the bag at a selected place where degassing causes no nuisance to others.
It comprises an elongated tube having a filter loaded therein, an opening-and-closing plug attached to its head end and a diverging joint formed at its tail end. The diverging joint can be attached to the circumference of a joint opening, which is made in the upper part of the bag.
When the bag is inflated with gas and excreta from the intestines, the patient can go to the men's room or somewhere for discharging the gas from the bag. Then, the excreta and liquid content are prevented from passing through the filter, only permitting the gas to flow therethrough. Thus, degassing can be put under the perfect control by the patient, so that there is no fear of permitting leakage of gas to cause nuisance to others or imprignation of his underwear with unpleasant odor before the patient is aware.
U.S. Pat. No. 5,957,907
Inventor: Barbara Oakley Sauer
Issued: Sep. 28, 1999
An absorbent article includes a close fitting bodyside liner having an opening therein. The opening defines a front end edge, a rear end edge, and a pair of laterally opposed side edges. The article also includes a pair of elastic members which extend longitudinally beyond at least one of the end edges of the opening in a laterally divergent direction. The elastic members may also extend at least partially along the side edges of the opening. The elastic members are configured to maintain the edges of the opening in contact with the wearer's buttocks and align the opening with the wearer's anal opening in use. The article may further include a liquid management material located on the bodyside liner in the front waist to absorb or contain liquid exudates.
While these devices may be suitable for the purposes for which they were designed, they would not be as suitable for the purposes of the present invention, as hereinafter described.
SUMMARY OF THE PRESENT INVENTION
The present invention discloses a pad to be worn by a user for absorbing gas due to flatulence. The pad is constructed of activated charcoal cloth disposed between a pair of laminations or layers having multiple perforations therei
