METHOD FOR INHIBITING FUNGAL AND BACTERIAL INFECTIONS OF THE FOOT

Abstract

A method for inhibiting fungal and bacterial infections of the foot enables a foot to be covered with a flexible, waterproof sheath while an upper region of the body is being washed. The sheath is donned on the foot before the upper region of the body is washed, so as to protect against carriers of the fungal contaminants, such as liquids, debris, and soap that flow towards the foot. The sheath is sufficiently sized and dimensioned, so as to snugly encapsulate the foot, and thereby inhibit moisture, soap, fungus, and bacterium that originate at the upper regions of the body from engaging the foot, anywhere from the ankle to the toes. The method enables the entirety of the foot to be covered with the sheath through a simple tugging motion. After washing the upper region of the body, the sheath is urged off the foot, and the foot is washed independently.

[0034] These and other features, aspects, and advantages of the present invention will become better understood with regard to the following description, appended claims, and drawings where:

[0035] FIG. 1 is a flowchart diagram of an exemplary method for inhibiting fungal infection of the foot;

[0036] FIG. 2 is a side perspective view of an exemplary sheath; and

[0037] FIGS. 3A and 3B are sectioned views of the sheath shown in FIG. 2 being donned on a foot, where FIG. 3A is a frontal view, and FIG. 3B is a bottom view.

DESCRIPTION

[0038] The present invention is directed to a method 100 for inhibiting fungal and bacterial infections of the foot, as referenced in FIGS. 1-3B. The method 100 is especially effective when an upper, or other region of the body is infected with a fungus or other biological contamination, and the foot 300 must be protected from the fungus and bacteria during washing, i.e., showering. The method 100 is configured to enable a foot 300 to be covered with a flexible, waterproof sheath 200 while an upper region of the body is being washed. The sheath 200 is donned on the foot 300 before the upper region of the body is washed, so as to protect against contamination as liquids, debris, soap, and other carriers of fungus to flow towards the foot 300. In some embodiments, the potentially contaminating fungus may include, without limitation, fungus, Athlete's Foot, nail fungi, foot ulcers, Onychomicosis, Lymphangitis, diabetics, gangrenous feet, and a biological contaminant.

[0039] Those skilled in the art will recognize that these fungal diseases are recurrent or first appear because of germs that colonize the pubic, anal, and other upper region areas of the body. The upper region of the body may include the region above the ankle 304s. Often, the fungal contaminants and related germs come from the daily wash down during showers of the upper region of the body. Specifically, the fungal contaminants originate in the genitals and stools in the anal area of the body. These germs, once they colonize an area of the body, such as the foot 300, may create blisters and cracks between the toes and nails. This causes deformities and huge expenses due to the use of medications and visits to the doctor and podiatrists.

[0040] Further, when these fungal contaminants penetrate the skin through the cracks, into the vessels, lymphatic system, subcutaneous tissue, they cause severe diseases, some of which are life threatening, including: cellulitis, erisipelas, vasculitis, deep venous thrombosis, and pulmonary embolism followed by death. Severe gangrene, amputations in diabetics and ulcers also can occur when the fungal contaminants are allowed to contact the foot 300.

[0041] As the flowchart in FIG. 1 illustrates, the method 100 may include an initial Step 102 of providing a sheath 200, the sheath 200 configured to snugly encapsulate the foot 300, the sheath 200 comprising an open end 202, a closed end 204, an elongated body 206, an inner surface 214, and an outer surface 212. The open end 202 receives and enables passage of the foot 300. The closed end 204 engages the toes 302 to indicate that the sheath 200 is fully donned. The elongated body 206 extends between both ends 202, 204, forming a barrier for the foot 300 against the above mentioned fungal contaminants. The outer surface 212 engages liquid, soaps, and other carriers that may contain the fungal contaminants. The inner surface 214 engages the skin of the foot 300.

[0042] Turning now to FIG. 2, one embodiment of the sheath 200 may be formed as a flexible, waterproof condom-like device, configured to snugly encapsulate the foot 300. The sheath 200 is configured to follow the general contour of a foot 300. In one embodiment, a left-footed sheath is used to cover the left foot, and a right-footed sheath is used to cover the right foot. In one embodiment, the sheath 200 is fabricated from a waterproof fabric (either treated or laminated with a wax or PVC or PU). The sheath 200 may be stitched and then taped along the stitching to ensure a waterproof seal, similar to a diver's dry suit.

[0043] Suitable materials for the sheath 200 may include, without limitation, latex, elastomer material, nylon, rubber, and polyurethane. Though the sheath 200 is fabricated from latex, there may be an option to create a non-latex version for those with latex allergies. Such a material may include vinyl, nitrile rubber or neoprene, which are all alternatives to natural rubber latex.

[0044] The sheath 200 may be manufactured and packaged for sale in a number of ways known in the art, i.e., dip molding, vulcanization, sterilization, and packaging. In one embodiment, the sheath 200 can be manufactured in one simple process and then packaged into a box, much like sterile medical gloves are packaged. Table 1, below focuses on some of the main processes that may be used for manufacturing, sterilizing, and packaging the sheath 200. TABLE 1 is as follows:

Weaknesses: A further process increases the overall cost. Opportunities: Further branding can be printed on packaging. Threats: Added cost in manufacturing process.

[0045] In some embodiments, a Step 104 may further include orienting the open end 202 of the sheath 200 towards the toes 302 of the feet. In donning the sheath 200, the sheath 200 is oriented towards the toes 302. The rim 208 at the open end 202 of the sheath 200 is stretched wide, so as to allow passage of the foot 300. The open end 202 is sized and dimensioned to enable the foot 300 to pass through with minimal obstruction. In one embodiment, the sheath 200 may have various sizes that fit differently sized feet. In another embodiment, a powder may be applied to the inner surface 214 of the sheath 200 to minimize friction with the foot 300.

[0046] In some embodiments, the method 100 may include a Step 106 of urging the closed end 204 of the sheath 200 towards the toes 302. In donning, the open end 202 of the sheath 200 is oriented towards the toes 302. A slight tugging motion may be applied to urge the open end 202 of the sheath 200 past the toes 302, and further to urge the elongated body 206 along the length of the foot 300. The sheath 200 is fully donned when the closed end 204 of the sheath 200 engages the toes 302.

[0047] As FIGS. 3A and 3B show, a Step 108 may include encapsulating the foot 300, such that the elongated body 206 of the sheath 200 extends from the toes 302 to the ankle 304. The sheath 200 is entirely donned when the open end 202 encircles the ankle 304 and the closed end 204 engages the toes 302. In this manner, the sheath 200 is sufficiently sized and dimensioned, so as to snugly encapsulate the foot 300.

[0048] Because the sheath 200 is sized approximately the same as the foot 300, the sheath 200 forms a snug fit around the foot 300. The open end 202 of the sheath 200 may include an elastic rim 208 that constricts around the ankle 304. The rim 208 may include a rubber rim 208 to ensure a skin tight seal against the skin.

[0049] The closed end 204 of the sheath 200 may include a reinforced patch 210 that resists tearing by the nails on the toes 302. The substantially elastic configuration of the sheath 200 sticks to the surface of the skin to prevent slippage. The body 206 of the sheath 200 may be transparent to enable viewing of the foot 300.

[0050] In one exemplary donning of an exemplary sheath, a waterproof sheath for the forefoot is formed as a thin walled elastomeric water proof bag or tube, open at the open end. The sheath 200 stretches skin tight over the foot 300. The configuration of the sheath 200 enables the sheath 200 to circumferentially squeeze against the foot 300. The sheath 200 may be donned similarly to a stocking. The sheath 200 may also be donned before showering, bathing, or when immersing into a public douche, a pool, and a gym shower.

[0051] Another Step 110 includes sealing the open end 202 of the sheath 200 around the ankle 304. The rim 208 at the open end 202 of the sheath 200 constricts around the ankle 304 so that liquids are restricted from flowing into the inner surface 214 of the sheath 200, and into contact with the foot 300. It is significant to note that the sheath 200 is donned on the foot 300 before the upper region of the body is washed, so as to protect against contamination from the upper regions, or other parts of the body.

[0052] Thus, by forming a tight, compressed encapsulation of the foot 300 around the ankle, the moisture, soap, fungus, and bacterium originating at the upper region of the body is prevented from flowing down and engaging the foot 300. And the foot 300 is protectively covered from the ankle 304 to the toes 302. In this manner, a fungus or other biological contaminant that originates at the upper region, or other parts of the body is inhibited from transferring, i.e., washing, flowing, cascading, to the foot 300, and consequently causing infection thereof.

[0053] Another Step 112 involves washing an upper region of the body. The upper region of the body may include any region of the body above the ankle 304. It is known in the art that the fungal contaminants originate from the daily wash down during showers of the upper region of the body. Specifically, the fungal contaminants originate in the genitals and stools in the anal area of the body. These germs, once they colonize an area of the body, such as the foot 300, may create blisters and cracks between the toes 302 and nails.

[0054] A Step 114 includes urging the sheath 200 off the foot 300. After washing the upper and other regions of the body, the closed end 204 of the sheath 200 is pulled away from the toes 302. It is known in the art that when the sheath 200 is wet, removing it from the foot 300 may require tugging along the elongated body 206 and inching the sheath 200 off the foot 300. It is significant to note that contacting the foot 300 with the outer surface 212 of the sheath 200 should be avoided while urging the sheath 200 off the foot 300. In one alternative embodiment, a spray on latex product is applied to an inner surface 214 of the foot 300 to ensure that the foot 300 stays dry while showering and so that the sheath 200 easily peels off after use.

[0055] Yet another Step 116 includes washing the foot 300. The foot 300 is washed independently of the rest of the body. The foot 300 may be washed in a separate tub or stall than the upper region of the body was washed. Because the fungus and other biological contaminants are separated from the foot 300 during this subsequent foot washing, contamination of the foot 300 is prevented.

[0056] A final Step 118 comprises discarding the sheath 200. The outer surface 212 of the sheath 200 may be contaminated after washing the upper region of the body. Thus, it is prudent to discard the sheath 200 in a biological disposal unit. In one alternative embodiment, an additional step of the method 100 comprises moving away from a shower area after washing the upper region of the body. In either case, the foot 300 is constantly segregated from the rest of the body during the entire washing process.

[0057] In essence, the sheath 200 is disposable, affordable, and easy to don prior to washing the upper regions of the body. By utilizing the sheath 200 in the method 100 disclosed herein, the prevention of occurrences of various diseases of the foot 300, such as Athlete's Foot, Onychomicosis, and diabetic foot ulcers may be prevented.

[0058] While the inventor's above description contains many specificities, these should not be construed as limitations on the scope, but rather as an exemplification of several preferred embodiments thereof. Many other variations are possible. For example, the outer and inner surfaces 212, 214 of the sheath 200 could be coated with an anti-bacterial composition. Accordingly, the scope should be determined not by the embodiments illustrated, but by the appended claims and their legal equivalents.
