Description

DEVICE FOR THE TREATMENT OF ATHLETE'S FOOT The invention relates to a device for preventing, treating and/or curing athlete's foot and to footwear comprising such a device.
Athlete's foot, or tinea pedis, is a contagious skin infection of the foot caused by fungus. It may infect any part of the foot, but it most often starts to grow between the toes to cause itchy white patches. The bottom of the foot close to the toes is also prone to infection, resulting in red, sore and flaky patches on the skin. More severe symptoms are a cracked skin and bleedings. The fungus can ultimately spread to the toenails and cause a fungal nail infection, which is much more difficult to treat than the initial symptoms that are limited to the top layer of the skin. It is therefore important to treat athlete's foot when the symptoms are stil! mild.
The fungus can be treated with creams, sprays or powders from a pharmacy. There are also appliances that can be worn in footwear, providing physical spacing of the toes combined with cushioning. In addition, some appliances achieve moisture absorption and aeration of the toes. Such appliances may also be effective as a prophylactic measure.
However, known devices for spacing, cushioning and aeration of the toes have proven insufficient in preventing, treating and/or curing athlete's foot, in particular they are not providing sufficient air circulation.
Another issue with many known devices is their wearing comfort, in particular devices that are designed as a single piece to be worn on and between (nearly) all toes. Such devices restrain the toes, which makes them thicker and leads to even more restraint.
It is therefore an objective of the present invention to provide a device for preventing athlete's foot which is more effective than known devices, in particular a device that provides sufficient air circulation around the toes. lt is also an objective to improve the wearing comfort of such a device.
It has now been found that one or more of these objectives can be reached by providing a device with an improved design for preventing athlete's foot.
Accordingly, the present invention relates to a device for preventing athlete's foot, the device comprising - a hollow body (2) having a body wall (3) extending from a first end (2a) of the hollow body to a second end (2b) of the hollow body (2), the body wall (3) defining an inner space (4) of the hollow body (2); - one or two flanges (5), each of which is present at an end (2a, 2b) of the hollow body (2) and protrudes from the body wall; wherein the device (1) comprises at least one opening (6) that allows fluid communication between the inner space (4) and an environment outside the device (1).
Figure 1 displays a three-dimensional view of a device according to the invention.
A device of the invention is designed to fit between the toes of a human or an animal. lts main component is a hollow body, typically made of a flexible material. The hollow body may in principle have any shape, as long as it is suitable for positioning between the toes. Regardless of the shape of the hollow body, at one or two positions of the hollow body is mounted a flange. These positions are two ends of the hollow body, i.e. a first flange is present at the first end and a second flange is optionally present at the second end of the hollow body. Thus, in the case of two flanges, these are mounted at two opposite positions of the hollow body. When a device of the invention is worn by a person, the one or two flanges themselves are not present between the toes but reside above and below them. In this way, the device of the invention stays better in position during use than known devices.
The hollow body comprises a body wall, or may even consist of a body wall. For example, when the hollow body is a cylinder, then the body wall corresponds to a cylinder wall. At one or both ends of such cylinder is then connected a flange. In the case of two flanges (one on either end), a device of the invention typically has the shape of a dumbbell.
The hollow body may also be of a cylinder-like shape rather than being a perfect cylinder with a round cross-section (a round cylinder). For example, the cylinder may be curved and/or have a variation in thickness. The latter variation may be along its circumference or in the elongated direction between both ends (perpendicular to the circumference).
For example, the cylinder is an elliptic cylinder. By an elliptic cylinder is meant that the (perpendicular) cross-section of the cylinder is an ellipse.
The cross-section of the cylinder may also have another non-circular shape. In such case, the cross-section is preferably any curved convex shape. A shape or object is considered to be convex when it is curved outward (in a convex shape, a line connecting any two points somewhere within the shape should not go outside the shape). A curved shape (as compared to one with corners, e.g.
polygon) has the advantage of less irritation when the device is in contact with the skin.
When a hollow body with an elliptic cross-section is placed between two toes, the long dimension of the ellipse is preferably in same the direction as the direction wherein the toes extend from the foot, while the short dimension of the ellipse intersects the two toes. This in principle also applies to any devices with a hollow body of any cross-section that has different cross-sectional diameters.
In a preferred embodiment, the hollow body comprises a coil. Such coils are known as a tube coils or helically wound pipes, which are in fact tubes/pipes formed by bending a long strip or thread in the shape of a spiral. The coil or helix thus formed can be considered as a cylinder having one elongated opening that spirals between the spiraling strip or thread from one end of the cylinder to the other end of the cylinder. In such arrangement, the body wall of the hollow body comprises at least one elongated spiraling opening. In the case of a coil, the hollow body may also have the variations in shape as described above, such as the cylinder-like shapes including the cylinders with circular and non-circular (convex) shapes.
In a device of the invention, the body wall of the hollow body may thus be formed by a strip of material that is bent in the shape of a coil. In the hollow body thus formed, the space between the windings of the coil may be present as the only opening in the device.
The body wall (as well as the one or two flanges thereon) may in principle be made of any material that is suitable for placement between toes, in particular between toes that suffer from athlete's foot. Preferably, the material is a flexible material, such as a rubber or a polysiloxane. By a flexible material is meant a material that can be bent or folded without permanent deformation and without breaking. It thus reverts to its original shape in the absence of a force previously exerted on the material to deform it. For example, in a device of the invention, the hollow body may be compressed to at least 25% of its diameter without permanent deformation and breaking.
Preferably, a device of the invention is made in one piece from one type of material. For example, when different parts of the device (such as the hollow body and the one or two flanges) are first prepared separately and merged at a later stage, surface irregularities may be formed (e.g. ridges), which may cause irritation of the skin. A smooth surface of the device is of high importance since the device is in contact with the skin, which skin may be sensitive and vulnerable due to the athlete’s foot condition. Therefore, generally, all edges that are present in a device of the invention are rounded, such as edges of openings and the contours of the one or two flanges.
A device of the invention comprises one or more holes or openings. Preferably, the hollow body of the device comprises one or more holes or openings. An important function of these one or more openings is that they allow fluid communication between the inner space of the hollow body and an environment outside the device. This means that the openings allow a fluid (a gas or a liquid) to pass from the inner space to the environment outside and vice versa. Thus, the openings generate a fluid connection between the inner space and the outside environment. When using a device of the invention, the openings’ main function is to allow the passage of air.
In the embodiment where the hollow body comprises a coil with one elongated spiraling opening, the presence of only one opening in the device is in principle sufficient to achieve a proper functioning of the device of the invention.
In embodiments wherein the openings are not so elongated, it is however preferred that there are more openings, for example at least 2, at least 3, atleast 5, at least 8, atleast 10, at least 15, at least 20, at least 25, at least 30, at least 35, at least 40 or at least 50. Usually, the number of openings in the range of 6-50, in particular in the range of 10-40.
An opening in a device of the invention, in particular in the hollow body thereof, is regarded as an equivalent of a surface, and is therefore considered to have two dimensions. Usually, an opening has at least one dimension that is at least 1.0 mm. Preferably, two of its dimensions are at least 1.0 mm. The surface 5 area of an opening is usually in the range of 1-20 mm?. In the case the hollow body comprises a coil, the surface area of an opening is usually in the range of 10-800 mm?, in particular in the range of 20-200 mm?.
A device of the invention may comprise an opening at one or both ends of the hollow body. This means that such opening is located at that side of the flange that is opposite to the side where the hollow body is connected to the flange. Such opening allows fluid communication between the inner space and an environment outside the device. Preferably, a device with such opening also comprises at least one opening in the hollow body. Such device then comprises at least two openings, which has the advantage that it improves the air circulation from the inner space to the outside environment and vice versa. This, on its turn, results in a better ventilation of the toes.
In case the hollow body is of a cylindrical shape (round, elliptical or other shape), then such opening(s) result in the cylinder being open on the respective end.
When a device with a cylindrical hollow body comprises only one opening, it is typically present in the body wall as one elongated spiraling opening.
When a device with a cylindrical or cylindrical-like hollow body comprises two or more openings, at least one opening is present in the in the body wall. Other openings are then present either in the body wall or at an end of the cylinder.
A device of the invention comprises one or two flanges on either end of the device. The function of the flange(s) is to secure the device between the toes of a user of the device. The one or two flanges themselves is/are not present between the toes but reside above and/or below them. When the device comprises only one flange, one end remains without a flange. The securing of the device between the toes is then not as good as with a flange on either side, but this may still be sufficient, depending on the person using the device, the presence of eventual footwear and the physical activities performed by the person.
A flange protrudes from the body wall, typically in a circumferential manner, Le. a flange protrudes from the body wall around the entire circumference of the hollow body. A flange may be of a flat shape such as the shape of a disc (a thin circular object). It may also have a conical shape, wherein the smaller diameter section of the cone blends with the hollow body to become an integrated whole; and wherein the larger diameter section forms the protrusion. Whereas a disc-shaped flange typically aligns with the normal to a cylindrical hollow body, a cone-shaped flange may have an angle of up to 60° with such normal, in particular of up to 45° or up to 30°. A smaller angle provides better securing between the toes than a larger angle.
In an embodiment, the hollow body has a non-circular cross-section and the flange is non-circular. In particular, the hollow body has an elliptic cross-section and the flange is elliptic. In such case, the shortest dimension of the hollow body cross-section is preferably perpendicular to the shortest dimension of the elliptic flange, when viewed along the axis that runs from the first end to the second end of the hollow body. When positioned between the toes, an improved securing is achieved with this configuration, since the longest dimension of the hollow body cross-section runs parallel to the toes and the longest dimension of the flange is perpendicular to the toes.
When the hollow body is formed by a coil (as described above), the coil may also form the one or two flanges. This is typically accomplished by providing larger windings of the coil near one or both ends of the coil (and thus one or both ends of the hollow body). In this way, the one or two flanges can be shaped at either end of the hollow body and the whole device may consist of one coil. Thus, a device of the invention may comprise, or may even consist of, a coil, wherein the coil constitutes the hollow body as well as the one or two flanges.
A device of the invention may comprise an active pharmaceutical ingredient such as an antifungal agent, an antibacterial agent and/or an antiviral agent. The device is then typically designed to release such agent from the device, thereby allowing migration of the agent to the infected skin. The device may however contain an active agent (or a combination of active agents) as a non-releasable coating on the surface that comes into contact with infected skin. For example, metallic silver may be present at the surface.
The size of a device of the invention is in fact dictated by the size of the human (or animal) foot, because the device is designed to fit between the toes of a human. Therefore, the distance between the two ends of the hollow body is usually in the range of 1-5 cm, in particular in the range of 2-4 cm. Also, the largest dimension of the one or two flanges is usually in the range of 1-5 cm. The device usually fits in a sphere with a radius in the range of 2-8 cm, in particular of 3-7 cm, more in particular of 4-6 cm. The inner space usually has a volume in the range of 0.5-125 cm3, in particular in the range of 1-25 cm3, more in particular in the range of 3-15 cm3. The diameter of the cross-section of the hollow body is usually in the range of 0.5-5 cm, in particular in the range of 2-4 cm or in the range of 1-3 cm.
A device of the invention is designed to be positioned between the toes of a person. lis application is however not limited to humans; it may also be used for animals. It is then placed between the toes, hoofs, or equivalent body parts.
The benefits of the device can manifest during any activity of the person (or animal) wearing the device. During walking, for example, the device is repeatedly compressed and decompressed. This results in a subsequent decreasing and increasing of the volume of the inner space, so that passage of air occurs through the or more openings. The displaced air then results in ventilation around the toes, thereby preventing or reducing the occurrence of athlete’s foot.
It is however not necessary to move the feet to experience the beneficial effects of a device of the invention. Also when the wearer of the device is sitting still or is asleep, the device improves the accessibility of air to the infected skin at and/or near the toes. lt is preferred that for this use, the device comprises atleast two openings.
A device of the invention may in particular be used with bare feet, ie. without any footwear such as shoes, socks, slippers, sandals and boots. In practice, this will often be during sleep. The absence of footwear allows more and faster evaporation of sweat and other residual water from the skin than when a foot is enclosed in footwear, which is beneficial because it is common practice to mitigate the fungus by decreasing the humidity of its surroundings.
An advantage of a device wherein the hollow body comprises a coil, is that, independent of the positioning between the toes, a significant portion of the opening is not blocked by abutting skin, so that there is always enough ventilation around the toe. Also when there are a plurality of openings, in particular at least eight, which are evenly distributed around the surface of the hollow body, the toes become sufficiently ventilated. Another advantage of such device is that it has an improved wearing comfort, since it does not restrain the toes.
Yet another advantage of such device is that it can conveniently be prepared in one piece, thereby severely reducing the occurrence of undesired surface irregularities.
The invention further relates to footwear comprising a device as described above. The footwear is for example selected from the group of shoes, socks, slippers, sandals and boots.
The invention further relates to an animal comprising a device as described above. In particular, the device is present between the toes (or the equivalent animal body portions) of the animal.
The invention further relates to a method of treating a human or animal foot suffering from athlete's foot or tinea pedis, comprising placing a device as described above between the toes of the human or animal. The method may also concern a prophylactic treatment, for example to be applied by a person before he or she is entering an area, such as a swimming pool or sanitary facilities, where he or she may get infected.
The invention further relates to the use of a device as described above for the treatment of athlete's foot, or tinea pedis.
