Description

IMPROVEMENTS RELATED TO SOCKS DESCRIPTION OF THE INVENTION The present invention relates to a sock suitable to be carried on a limb and particularly to a sock for use on the leg. The sock is particularly suitable for use with a compression device for the limb and in the type of compression therapy used in the treatment of venous leg ulcers, deep vein thrombosis (DVT), vascular disorders and edema reduction . The invention also relates to a pair of such socks and to a device comprising such a sock. Ulceration of the lower limbs affects a significant proportion of the age population over the age of sixty. Although there are several forms of ulcer, one of the common ones is the venous ulcer of the legs, which is believed to result from the failure of the valves within the venous system. The failure of these valves reduces the efficiency of blood return from the limb and it is believed that this correlates with the incidence of ulceration. Various leg ulcers are currently treated by the use of a bandage for the wound and the application of compression to the affected limb. The compression is conventionally applied either through the use of REF: 176247 bandages or stockings, with the tension within the structure of the fabric of these products that generates force with pressure. The effectiveness of bandages, which allow the passage of water vapor from the wound, is impaired by the application of conventional compression materials, particularly bandages. Some of the wound exudates may leak around or through the bandage, creating moisture; this fluid contains enzymes that can cause maceration of the surrounding skin, which of course is undesirable. Bandages or stockings are also not comfortable to wear, especially in warm weather, since moisture can not escape easily. With bandages and stockings, bony prominences, such as the shin bone and the ankle bone, receive levels of pressure, concentrated and therefore a lower layer of soft nonwoven filler is also used, to fill the limb and make to its more circular cross section. This filler can also perform the function of absorbing any fluid that escapes from the bandage. However, it is difficult and requires' skill to perfect the work to place the filling properly, and the bandages can subsequently move and detach the filling. Compression can also be applied using a constricted air bladder, which resolves some of the problems associated with the use of bandages and stockings. The air bladder itself is impervious to steam and this can therefore cause problems, since the heat and moisture from the sweat are trapped by the bladder. Accordingly, there is a need for means to alleviate the problems associated with the use of known compression systems for patients with leg ulcers. The present invention provides, in a first aspect, a sock or sock suitable to be worn on a limb of a patient with a leg ulcer, the sock comprises material having the ability to remove moisture away from the surface of the skin at all times. regions. Some, most, substantially all or all of the ankle portion of the sock may comprise material that has the ability to absorb moisture away from the surface of the skin. Preferably, the entire area, or substantially the entire area, which in use will be coextensive with the patient's ankle, comprises material that has the ability to absorb moisture away from the surface of the skin. All, or substantially all, of the sock gaiter region may comprise material that has the ability to absorb moisture away from the patient's skin. Preferably, the sock comprises material that has the ability to absorb moisture away from the surface of the skin in all regions. Such a sock is advantageous since it can be carried on the leg of a patient with a leg ulcer, on a bandage for the wound, while not damaging the effectiveness of the bandage, which allows the passage of water vapor from the wound. Consequently, sock carrying can help keep skin healthy in the ulcer region. The sock is particularly effective for use by patients with leg ulcers who have leg ulcers in the region of the leggings, which is the area in which leg ulcers are most common. The material that has the ability to absorb moisture away from the surface of the skin, can be any material with moisture-absorbing properties. In particular, the material can be fibers that have the ability to absorb. The fibers may be suitably knitted in the sock, and the sock may be knitted from a wicking fiber or from a combination of two or more different fibers including one or more wicking fibers. Suitable wick fibers include Cool ax * 0 *, Duraspun1111, Isolfil ™, polypropylene, polyester microfiber and Soft Touch1® P180W and Galaxy101 or other fibers with a large surface area. When fibers other than wicking or absorption fibers are included, these may be any fibers suitable for use in a sock and may be natural fibers or synthetic fibers or a combination thereof. Preferably, the sock comprises a mixture of cotton and Coolmax Antibacterial1111 fibers or a mixture of cotton and polypropylene. The mixture may comprise 5% to 80% by weight of the absorption or wick fibers; and preferably from 20% to 60% by weight of absorption fibers or wick, and more preferably from 25% to 50% by weight of the absorption fibers mixed with natural or synthetic fibers suitable for use in a sock. Absorption is the transport of fluid within a thread or fabric structure. This process is governed by the arrangement of the fibers that comprise the structure, and by the ease with which the fluid moisturizes the surface of the fiber. Preferably, the sock is knitted by stitches with a mesh pattern that promotes the transfer of moisture to other areas of the sock. Useful stitches / processes for producing useful stitches or knits include rib knit, ribbed loop transfer, flat loop transfer, single jersey or plain double knit, and double jacquard knit stitch. In particular, stitch patterns that promote moisture transfer to sock areas that, in use, will not be covered by the patient's shoe or compression sleeve, are preferred. More preferably, stitch patterns that promote moisture transfer to the sock areas that, in use, will not be covered by the patient's shoe, or by any means of applying compression, such as bandages, compression stockings, Compression sleeves, or air bladders, that are worn by the patient, can be used. Preferably, the material having the ability to absorb moisture from the surface of the skin, includes one or more absorbent fibers on the side of the material, which in use are on the inner surface of the sock, adjacent to the skin, and include absorbent material such as absorbent fibers, on the side which in use is outer surface of the sock. For example, the material that has the ability to absorb moisture from the surface of the skin may be an absorbent fiber, or from a combination of two or more different fibers including one or more absorbent fibers, located on the side that in the use is on the inner surface of the sock, while it can be knitted from an absorbent fiber, or from a combination of two or more different fibers including one or more absorbent fibers, on the side that in use It is on the outer surface of the sock. In this way, one objective of the absorbent fibers is, in many embodiments, to transport the moisture to the outer part of the sock. When the sock is used in combination with a compression sleeve, one objective of the absorbent fibers is to transport the moisture to those areas of the sock not covered by the compression sleeve, or to those areas from which the evaporation of the sock is possible. humidity. The sock can suitably comprise ventilation channels that run away from the ankle portion, along which the water vapor can be transferred laterally, for example by means of diffusion and / or by air flow, currents or convection. The ventilation channels can be suitably of a grooved construction. The sock may comprise a foot portion that includes ventilation channels that run away from the ankle portion, along which the water vapor may be transferred laterally, for example, by diffusion and / or by air flow, currents or convection. The sock may alternatively or additionally comprise a leg portion which includes ventilation channels that run away from the ankle portion, along which the water vapor may be laterally transferred, for example, by diffusion and / or by flow of air, currents or convection. The sock preferably further comprises a leg portion that includes an elaborate area of the material that has the ability to absorb moisture away from the surface of the skin. The material that has the ability to absorb moisture away from the surface of the skin can be as described above, in relation to the ankle portion and may be the same as, or different from the material that has the ability to absorb moisture away from the surface of the skin, used in the ankle portion. The sock preferably further comprises a foot portion that includes an elaborate area of the material that has the ability to absorb moisture away from the surface of the skin. The material that has the ability to absorb moisture away from the surface of the skin may be as described above, in relation to the ankle portion and may be the same as, or different from, the material having the ability to absorb moisture. away from the surface of the skin, used in the ankle portion. The present invention also provides, in a second aspect, a sock suitable for dressing on a leg of a patient with a leg ulcer, the sock comprises an elaborate ankle portion of the material having the ability to apply compression to the area of the foot ankle. of the patient. Some, most, substantially all or all of the ankle portion can be made from the material that has the ability to apply compression to the ankle area of the patient's foot. Preferably, all or substantially all of the area which, in use, will be coextensive with the ankle of the patient, is made of the material having the ability to apply compression to the ankle area of the patient's foot, and most preferably the entire legion region. The sock is made of the material that has the ability to apply compression to the ankle area of the patient's foot. The use of such material that has the ability to apply compression in the sock is advantageous because it allows compression to be applied to the ankle area without restricting the movement of the ankle joint. Conventional compression means tend either to have difficulty in applying compression to complex moving areas such as the ankle region, or are unable to apply compression to such areas without causing a restriction in flexibility. In addition, the use of such material provides additional support to this sensitive area. Preferably, the material having the ability to apply compression to the ankle area of the patient's foot comprises two or more different fibers, for example, this can be knitted from two or more different fibers. Preferably, the material includes one or more elastic fibers, for example, selected from Lycra101, elastane, Spandex ™ 1, Dorlastan, Spnazelle * 01, Vyrene1111, natural rubber EDPM and polybutadiene. The Youngs modulus of the elastic fiber is suitably 105 to 107 Pa, for example, of the order of 106 Pa. When the different fibers of the elastic fibers are included, these may be any fibers suitable for use in a sock, and they can be natural fibers or synthetic fibers or a combination thereof. Suitably, the material is knitted material and the stitch used to knit by stitches is such that it generates compression. The peaks and fences, the opening of the stitch and any openings all contribute to the generation of compression and consequently one or more of these factors can be suitably adjusted to achieve the desired compression. Preferably, the portions of the sock other than the ankle portion and any sleeve portion that is included around the mouth of the sock, are made of material that has no significant ability to apply compression. The sock should preferably only apply compression in specific areas of its structure. In particular, it is preferred that portions of the sock other than the ankle portion and any sleeve portion that is included around the mouth of the sock, are made of material that does not include elastic fibers. It is preferred that sock portions other than the ankle portion and any sleeve portion apply minimal compression such as less than 10 mmHg, for example, less than 5 mmHg. There will of course be some variation in pressure depending on how large the leg on which the sock is to be carried. However, the sock is designed to fit specific leg sizes. Accordingly, sock portions other than the ankle portion and any sleeve portion adequately apply minimal compression, such as less than 10 mmHg, eg, less than 5 mmHg, when on one leg within the specified size range for the sock. Suitably, the sock portions different from the ankle portion and any sleeve portion, are knitted by stitches with an open stitch, in order to generate minimal compression. When the pressure applied to the sock is considered, for example, from a means of application of compression, such as bandages, compression stockings, the Law of LaPlace applies. Therefore, the pressure applied is inversely proportional to the radius, and the pressure is higher along the bone of the shin. This is minimized by maintaining the pressure applied by the sock, as low as possible, without it falling, in particular by having the sock portions different from the ankle portion and any portion of sleeve properly applying minimal compression, such as less than 10 mmHg, for example less than 5 mmHg. When the sock is used in combination with a compression sleeve, it is preferred that the sock does not have significant ability to apply compression in any region. This means that the only compression applied to the limb from the combination of the sock and the sleeve, is that applied by the compression sleeve and this allows greater control of the treatment distributed to the patient by the medical practitioner. The use of padding in the sock in areas that in use cover the ankle and shin is advantageous because, when used in conjunction with the compression application means such as bandages, compression stockings, compression sleeves or air bladders, this provides cushioning for those bony prominences, and in particular reduces the high pressures that may otherwise occur along the bony prominences when compression is applied. Suitably, the filling can be provided by the provision of a thicker layer of material, which is used in the surrounding region. For example, in a modality by which the sock is knitted by stitches, the areas of the fabric by thicker stitches, may be utilized in the areas of the ankle portion and the leg portion which, in use, will cover the ankle. and the shin, which is used in the surrounding region. The padding can be adequately provided by the use of loops, such as loops of sponge-like fabric in the areas of the ankle portion and the leg portion which, in use will be over the ankle and shin, on the side that is in use will be on the inner surface of the sock, adjacent to the skin. Loops of sponge fabric are of course well known in the art, for example, in towels and on athletic socks such as the heel for long distance use, and can be formed when the bottom or floor structure is knitted by dots on alternating needles with the remaining needles that are overlapped by the rear guide that causes the formation of the loops of thread protruding from the floor structure or the fabric. The loops of sponge fabric can be adjusted to size as desired to provide the required degree of padding, for example, extra large sponge loops can be used, with the larger loops providing more padding. The padding on the ankle may be material that is 1 mm thick or more, preferably 1.5 mm thick or more, for example up to 2 mm thick.

The shin filler may be material that is 2 mm thick or more, preferably 3 mm thick or more, more preferably 4 mm thick or more, for example, up to 5 mm thick. Preferably, an ankle is provided that is in accordance with two or more of the above aspects of the present invention. The sock can suitably be a knitted sock. The sock may be knitted from any suitable fiber or combination of fibers, provided that they meet the requirements described above. Fibers such as wool, cotton, viscose, Lyocel ^ / Tencel11, nylon, polyester, and silk can be suitably used in the sock of the present invention and in particular are suitable for use as base fibers that form most of the sock . Fibers such as wool, cotton, viscose, Lyocel ^ / Tencel1111 and silk can also be used in the sock as absorbent fibers. Fibers such as Coolmax ^, Duraspun * 111, isofil ™, polypropylene, polyester, microfiber, Soft Touch1111 P180 and Galaxy * 0 can be suitably used in the sock of the present invention, and in particular are suitable for use as fibers of wick or absorption. Fibers such as elastane, Spandex1, Dorlastanm, Spanzelle11, Vyrene1®, Lycram, EPDM natural rubber and polybutadiene can be suitably used in the sock of the present invention and in particular are suitable for use as elasticized fibers. Antimicrobial fibers such as Outlast101, X-Static1® and Amicor ^ may be suitably used in the sock of the present invention. The sock can be suitably knitted from a combination of fibers that include one or more fine natural fibers, in particular a first spun wool, merino wool and spun yarns, to increase the comfort of the sock on the patient's foot. The use of one or more of these fibers also helps in controlling the temperature and humidity in the foot. The sock can be suitably knitted from a combination of fibers including one or more antimicrobial fibers, such as silver fibers. Preferably, the sock comprises a foot portion having a closed toe. This is preferable because this avoids the patient's comfort because the feet of his foot become cold. The sock preferably comprises a leg portion which, in use extends upwardly from the foot to cover some of, most, substantially all or all of the calf of the patient. Suitably, the leg portion in use extends upwardly from the foot to cover the entire calf of the patient. Preferably, the leg portion of the sock ends at or about or just below the knee of the patient, and therefore the sock is preferably a high knee sock. Preferably, the sock comprises a portion of elastic sleeve around the mouth of the sock. The sleeve portion is preferably a double sleeve portion in order to increase the ability of the sock to remain there. The sleeve portion can suitably be 1 mm or more in thickness, and is preferably 1 mm to 5 mm in thickness, for example 4.5 mm in thickness. The sleeve portion preferably has seams on the side which, in use, is on the outer surface of the sock, in order to avoid rubbing against the skin and the formation of scabs or aids. Preferably, the foot portion is made of material that is of less friction on the side that in use is on the outer surface of the sock, than on the side that in use is on the inner surface of the sock. In one embodiment, the entire sock can be made of material that is less friction on the side that in use is on the outer surface of the sock than on the side that in use is on the inner surface of the sock. In consecuense, the design allows the inner part of the sock to have a higher coefficient of friction than the outer side. This is beneficial because it allows any compression application means carried with the sock to slip against the outer side of the sock without causing the inner part of the sock to rub against the skin, causing blisters to form or causing a bandage not to Occlusive applied to the wound is pursed at the edges. The sock suitably comprises a foot portion having the seams on the side which, in use, is on the outer surface of the sock. This is beneficial since it prevents rubbing against the skin and the formation of blisters. It is also preferable that the sock comprises a foot portion having a thin profile, since this allows the patient's normal shoe to be carried with the sock, even while the sock is also carried with the compression application means. Preferably, the sock comprises a foot portion that is less than 2 mm thick, more preferably less than 1 mm thick, for example 0.75 mm thick or less. The sock of the present invention suitably comprises an elastic ankle portion. For example, the ankle portion can be made of a material that includes one or more elastic threads, for example Lycra ™. This allows the sock to be put on and removed more easily, and also allows the ankle to flex. Preferably, the sock is padded around the ankle portion. For example, the ankle portion can, on the side that in use is on the inner surface of the sock, have loops of sponge tissue. Such loops can be suitably provided to be, in use, in a circular pattern around the ankle. The use of such a filler provides support for the sensitive area around the ankle. The ankle portion can be made of material that is 1mm thick or more, for example, 1.5mm or more; Properly, the ankle portion is made of material that is 1mm to 5mm thick. In one embodiment, the ankle itself includes an indication of the leg / foot size range for which it is intended, for example, the sock may include a label indicating the size range of the leg / foot for which it is intended. Alternatively, or additionally, the sock may be sold in a package indicating the size range of the leg / foot for which it is intended. The sock can be put on its own or it can be worn with the compression application means such as bandages, compression stockings, compression sleeves or air bladders. The socks can be unilateral, with a sock that is a sock for the left foot and one that is for the right foot. The invention further provides an equipment comprising one or more socks according to one or any combination of two or more of the above aspects, together with one or more compression application means, such as bandages, compression stockings, sleeves of compression and air bladders. In one embodiment of this aspect, the sock comprises ventilation channels and the compression application means comprises evaporation channels which, in use, correspond to the ventilation channels in the sock, to allow the water vapor to diffuse to along the ventilation channels and then be released into the atmosphere from the evaporation channels. An embodiment of the present invention will now be further described, by means of examples only, with reference to the figures in which: Figure 1 is a diagram of a sock according to the present invention; Figure 2 is a diagram of a pair of socks according to the present invention; and Figure 3 is a diagram of an equipment including a sock according to the present invention. The sock shown in Figure 1 is shaped to fit over the foot and calf of the patient with leg ulcer and comprises a foot portion 2 and an ankle portion 3 leading to a leg portion. A sleeve portion 5 is provided in the upper portion of the leg portion 4, around the mouth 6 of the sock 1. The sock 1 is a sock at knee height, with the leg portion 4 in use that is extends in an upward direction from the patient's foot to cover the entire calf of the patient and ending in the sleeve portion 5, on or around the patient's knee. The ankle portion 3 is knitted by stitching from a combination of cotton and / or wool together with the Coolmax1 absorbent fiber, antibacterial silver fibers and the Lycra ™ elastic fiber. This portion of the sock applies compression of approximately 70 mmHg. The foot portion 2 and the leg portion 4 are knitted by stitching with an open stitch from a combination of cotton and / or wool together with the Coolmax® absorbent fiber and antibacterial silver fibers. These portions of the sock apply minimal compression, less than 5 mmHg. The ankle portion 3 includes the filling 7, by the use of loops of extra-large sponge fabric, in the area that in use will be on the ankle, on the side which in use will be on the inner surface of the sock adjacent to the ankle. skin. The filling 7 by the ankle is approximately 1.5 mm thick. The leg portion 4 includes the padding 8 by using loops of extra-large sponge tissue in the area, which, in use will be on the shin, on the side which in use will be on the internal surface of the sock, adjacent to the pad. the skin . The filling 8 by the shin about 4 mm thick. The foot portion 2 has a closed finger 9 and has seams on the side which, in use, is on the outer surface of the sock 1. • The foot portion 2 has a thin profile, approximately 0.75 mm thick. The sock 1 comprises ventilation channels 10 of grooved construction provided both in the foot portion 2 and in the leg portion 4. The ventilation channels 10 run away from the ankle portion 3, and the water vapor can be transferred laterally by diffusion along these channels 10. The sleeve portion 5 is elastic and is approximately 1.5 mm thick. The sleeve portion 5 is a double sleeve portion and comprises pieces of synthetic rubber. The seams of the sleeve portion 5 are provided on the side which, in use, is on the outer surface of the sock 1; The sock 1 includes a label (not shown) on its internal surface, whose label indicates the size of the leg on which the sock will be used, in order to generate the desired pressure. Sock 1 can be properly placed on the foot and calf of a patient with a leg ulcer, on any bandages placed on the wound. Sock 1 allows moisture to be distributed away from the skin and into the atmosphere. Further, when used with a compression application means, for example, bandages or a compression sleeve, the padding 7, 8, in the sock 1 prevents high pressures from being applied to the bony areas of the ankle and shin. Figure 2 shows a pair of socks 100 comprising a left sock 101a and a right sock 101b. Each of the socks 101a, 101b is like the sock 1 shown in Figure 1 and described above. In Figure 2, a reference number 100 greater than a reference number in Figure 1 indicates a similar part; for example, in Figure 2 the reference number 103 indicates an ankle portion corresponding to the ankle portion 3 shown in Figure 1 and described above. Figure 3 shows a kit 200 comprising a sock 201 and a compression sleeve 220. The sock 201 is like the sock 1 shown in Figure 1, and described above. In Figure 3, a reference number 200 greater than a reference number in Figure 1 indicates a similar part; for example, in Figure 3 the reference number 203 indicates an ankle portion corresponding to the ankle portion 3 shown in Figure 1 and described above. The compression sleeve 220 is shaped to fit over the foot and calf of a patient with a leg ulcer, on the sock 201, and comprises a foot portion 221 and a leg portion 223. The compression sleeve 220 is at knee height, with the leg portion 223 in use extending with the direction from the patient's foot to cover the entire calf of the patient and finish in the mouth 224 at or around the patient's knee, at or slightly above above the height of the sock 201. The compression sleeve 220 is provided with inflatable and deflatable bladders (not shown) which are used to apply compression to the leg of the patient with a leg ulcer. The foot portion 221 of the compression sleeve 220 has an open finger 225. The compression sleeve 220 comprises evaporation channels (not shown) which, in use, correspond to the ventilation channels 210 in the sock 201. Accordingly , the water vapor can diffuse along the ventilation channels 210 and then be released into the atmosphere from the evaporation channels. The sock 201 can be suitably carried on the foot if the calf of the patient with leg ulcer, on any bandages placed on the wound, with the compression sleeve 220 that is carried on the sock 201. The sock 201 shows that the humidity is distributed away from the skin and into the atmosphere. In addition, when used with a compression application means, the sock filling 201 prevents high pressures from being applied to the bony areas of the ankle and shin. The compression sleeve applies pressure as required to the patient's foot and calf. The sock 201 preferably does not apply compression to the limb and is uniformly knitted from a mixture of textile fibers such as cotton and an absorbent fiber. In this way, moisture can be absorbed from the entire surface of the skin under the compression sleeve, and allowed to evaporate from those areas of the sock not covered by the compression sleeve. The embodiments of the present invention will now be described, by means of the following example.

EXAMPLE 1 Socks made from various yarn blends were tested in forty wash cycles to determine those blends with the best absorption properties.

Sample No. Yarn mix (count system Nm) 1 1/40 cotton x 1/50 Coolmax / antibacterial Coolmax 2 1/40 cotton x 1/50 polypropylene The socks were subjected to lateral absorption tests carried out on the posterior section of the calf that runs down the length of the sock. The absorption results reflect the lateral movement of moisture along the length of the sock. The test was performed as follows: A sample size test was cut: 15 mm x 100 mm using a pair of scissors. A line of 10 mm is marked parallel to the bottom edge of 15 mm on each of the samples. Two platforms and clamps are placed, and a simple metal rod is attached to the clamps on each platform. It is ensured that the rod is horizontal. Three buldog-type pieces are attached to the metal rod, such that each clamp is approximately 10 mm apart. The laboratory support is placed under the metal rod with the clamps on both sides. 10 mm of eosin dye is placed inside each of the three adjacent chambers of a culture dish. The tray is placed on the laboratory support. Each unlabeled 15 mm end of the samples is attached to the buldog-type clamps, ensuring that the samples are vertically and horizontally straight and are directly above the chambers containing the eosin stain. The height of the laboratory support is increased until the level of the dye reaches the marked line (end of the sample submerged to the 10 mm line). Immediately the chronometer is started. After 60 seconds, the laboratory support is lowered, the test samples are carefully removed and the absorption distance furthest in mm from the marked line is measured.

It is noted that in relation to this date, the best method known to the applicant to carry out the aforementioned invention is that which is clear from the present description of the invention.
