    Patient sock and method of making sock
    Background
    FIELD OF THE INVENTION The invention relates to socks, and in particular to friction socks.
    Brief Description of the Invention
    It is therefore an object of the invention to provide a new sock for patient use and a method for making such a sock. The object of the invention is achieved by a sock and a method characterized by what is stated in the independent claims. Preferred embodiments of the invention are claimed in the dependent claims.
    The solution is based on the fact that the sock comprises a tubular mesh structure of monofilament monofilaments which elongates at least in the transverse direction.
    Some of the benefits of the solution are the breathability of the sock and the good fit of different sizes of legs, as well as the ease of manufacture.
    BRIEF DESCRIPTION OF THE DRAWINGS
    The invention will now be further described in connection with preferred embodiments, with reference to the accompanying drawings, in which:
    Figure 1 schematically shows a sock for patient use;
    Fig. 2 schematically shows a network structure;
    Figures 3a and 3b show schematically some socks for patient use;
    Figures 4a-4e show cross-sections of some monofilaments;
    Figure 5 schematically shows a method; and
    Figure 6 schematically shows a nozzle arrangement.
    DETAILED DESCRIPTION OF THE INVENTION
    Figure 1 schematically shows a sock 1 for patient use. Patient use may include the use of a sock for home care, hospitalization, or other institutional care, or the like. Usage situations may vary, including, for example, lying in bed, sitting and / or moving a patient, alone or assisted. Of course, the sock shown here is also suitable for other applications and the solution is not limited to the aforementioned uses.
    The sock 1 for patient use may comprise a tubular mesh structure 2, such as that illustrated schematically in Figure 2.
    20175379 prh 28 -04- 2017
    2. The mesh structure 2 is then, by its very design, breathable and thus not abrasive.
    The mesh structure 2 may be flexible at least in its transverse direction, i.e. transverse to the longitudinal direction of the tube. In this case, the mesh structure 5 can be fitted snugly to the shape of the legs, but uncompressed, to different sizes of legs and, for example, is also suitable for use with different patient clothing and / or medical equipment. In one embodiment, the mesh structure 2 may also be formed flexibly in its longitudinal direction.
    The mesh structure 2 may comprise monofilaments 3. In other words, the mesh structure 2 may consist of monofilament yarns. The monofilaments 3 may be monolithic or monolithic. In other words, the monofilaments 3 thus do not comprise a plurality of twisted filaments, possibly of different material layers, and no nested or adjacent layers of material, but consist of a single filament of the same continuous material throughout the entire cross-section of the monofilament. The monofilament 3 shown in Figure 2 is circular in cross-section, but in various embodiments, the monofilament 3 may also have an oval, square, polygonal or other suitable shape. Figures 4a-4e show some cross-sections of the monofilament20 road 3. Fig. 4a shows some first-order monofilament 3a and second-level monofilament 3b having a substantially circular cross-section. Fig. 4b shows some first triangular monofilament 3a and second level monofilament 3b having a substantially triangular cross-section. In one embodiment, the cross-section of the monofilament 3 may be selected to exert a massage effect on the foot.
    In one embodiment, the monofilament 3 may be tubularly arranged with a channel 11 provided therein, as in the embodiments of Figures 4c and 4d. In other words, the monofilament 3 may be hollow on the inside. Although the monofilament has a substantially circular cross-section in Figure 4d, it will be apparent to those skilled in the art that the monofilament may also vary in embodiments in which a channel 11 is provided inside the monofilament.
    In one embodiment, the mesh structure 2 may comprise fibrous pulp. The fibrous mass may comprise a material in which fibers are disposed within or inside the monolithic material. The term "pulp" does not refer to a fiber filament 35 in which the fibers are twisted or braided together or fitted, for example, in substantially parallel fiber bundles, but in a material in which the staple fiber is present.
    20175379 prh 28 -04- 2017 mixed with other material mixture. Embodiments comprising fibrous pulp are suitable, for example, for applications where it is necessary to reinforce the mesh structure against incisions caused by, for example, medical devices or other external objects, and where the mesh structure itself provides sufficient flexibility.
    In one embodiment, a material 11 other than the monofilament material may be arranged in the channel 11 provided inside the monofilament 3. In one embodiment, for example, fibrous pulp can be accommodated in the channel formed within the monofilament 3. In another embodiment, the pulp may be blended with a monolithic material. In yet another embodiment, the filament channel 11 provided in the monofilament 3 can be fitted with coated fibers or inserted into another monolithic material, as in Figure 4d. Here, however, it is also preferred that the first level monofilaments 3a and the second level monofilaments 3b 15 of the mesh structure 2 are welded to each other at their intersection points 4 with respect to each other, that is to say, the fibers or fibrous material that may fit inside the monofilaments 3.
    The monofilaments 3 may be arranged on at least two planes such that the monofilaments 3 of each plane are arranged substantially parallel to each other and intersect with the monofilaments of the next plane 3. That is, the mesh structure 2 may comprise a plurality of first level monofilaments 3a arranged substantially parallel to second level monofilaments 3b arranged parallel to the second plane. Each of the first level monofilaments 3a may be adapted to intersect at least one of the second level monofilaments 3b. These intersections of the monofilaments 3, 3a, 3b of the two planes form intersection points 4. Each monofilament 3, 3a, 3b intersects at least one intersection point 4 with the monofilament of the next layer. Outside the intersection points 4, both monofilaments of the same layer and filaments of mono30 of different layers can advantageously move relative to one another, preferably substantially freely.
    Preferably, the monofilament 3, 3a, 3b can be welded to the intersecting next layer monofilament. In other words, the first level monofilament 3a may be welded firmly to the first level side region of the second level monofilament 3b at the intersection point 4, i.e. at least the surfaces of the monofilaments 3a, 3b.
    20175379 prh 28 -04-2017 are then fused to each other at least in the intersecting region of the monofilaments 3a, 3b. The welding can advantageously be achieved by forming the mesh structure 2 by means of two extruded nozzles which are rotatable in opposite directions, each forming one level of monofilaments. Hereby, the mesh structure can be achieved in a single step without the need for special molds or similar special tools except for the nozzles, which speeds up and simplifies the manufacturing process. At the same time, coating and other work steps associated with coatings and similar manufacturing processes are avoided.
    In one embodiment, the sock 1 may be formed as a single substance. In this case, the sock 1 does not comprise any discrete layers of material or material fibers which are connected in one way or another, but are entirely made of the same material. In one embodiment, the sock 1 may be entirely formed by a monofilament mesh structure 2. In this case, the sock 1 will not comprise any discrete or interlocked portions of structure other than the mesh structure 2. In one embodiment, the sock 1 may be entirely formed of a monofilament mesh structure 2.
    In one embodiment, the monofilament 3 may be formed from a material having a high coefficient of friction. In particular, the monofilament 3 may be formed from a material having a higher friction coefficient, i.e. a higher resting coefficient of friction and / or motion friction relative to conventional flooring materials, than conventional socks such as cotton, wool, polyamide, acrylic and their. In this case, the sock 1 may act as a so-called friction sock, which may prevent slipping, for example, when standing up, when the patient is walking alone or when assisted or when lifting the patient. The socks 1 described in this specification are particularly useful as friction stockings, even when used with a variety of patient suits and medical devices, because of their formability, they can be easily fitted to different sizes of foot and, for example, to traditional patient socks or even medical equipment.
    In one embodiment, the mesh structure 2 may comprise a thermoplastic elastomer, for example a polypropylene-based thermoplastic elastomer. In one embodiment, the mesh structure 2 may comprise a synthetic rubber material such as styrene butadiene rubber (SBR).
    20175379 prh 28 -04- 2017
    In one embodiment, the mesh structure 2 may comprise monofilaments 3 comprising two different materials such that the first layer monofilaments 3a may comprise a different material than the second layer monofilaments 3b. In one embodiment, the monofilament 3, such as the first level monofilament 3a, facing the foot, such as the first level monofilament 3a, in the operating position may comprise a material having a coefficient of friction lower than that of the second level monofilament 3b. In this case, a sock 1 can be formed which is easy to put on the foot and at the same time provides an effective non-slip action between the foot and the base. Such a mesh structure 2 can advantageously be formed by two extruded nozzles arranged in opposite directions, each nozzle forming a monofilament on one level and the material fed to the first nozzle 8a being different from the material fed to the second nozzle 8b. In one embodiment, the first level monofilaments 3a 15 may comprise, for example, polypropylene and the second level monofilaments 3b may comprise, for example, EPDM (Ethylene Propylene Diene Monomer rubber) -filled polypropylene. Hereby, the inner layer can be made of a slippery and thus easily wearable and highly moisture permeable polypropylene, and the outer surface has a higher friction coefficient but which, due to the same substrate, can be easily welded to one another.
    In one embodiment, the weldable structures, such as first-level monofilaments 3a and second-level monofilaments 3b, or mesh structure 2 monofilaments 3, 3a, 3b and slider 5, comprise one or more monolithic materials having the same substrate. In such embodiments, it is easy to arrange welding of structures to one another. As shown in other embodiments, the welded structures may then comprise the same material or alternatively different materials, which, however, preferably have a common matrix, whereby they are welded to one another, but may still have different properties on different surfaces.
    In one embodiment, the mesh structure 2 may comprise two monofilaments 3a, 3b of different cross section, so that the first level monofilaments 3a may have a different cross section than the second level monofilaments 3b. In one embodiment, the monofilament 3, such as first level monofilament 3a facing the foot, such as the first level monofilament 3a, in its operating position may comprise a cross-section having a coefficient of friction less than that of the second level monofilament 3b6.
    20175379 prh 28 -04- 2017 surgery. An example of such an embodiment is shown in Figure 4e. In this case, in the operating position of the first level monofilaments 3a, the shape of the surface facing the foot may be smooth and / or narrow, for example rounded. Correspondingly, the use of the second level monofilaments 3b in the 5 position towards the substrate may be formed to increase friction and / or frictional surface, for example grooved and / or wider than the surface of the first level monofilaments 3a per foot. Hereby a sock 1 can be formed which is easy to put on the foot and which at the same time provides an effective non-slip action between the foot and the base. Such a mesh structure 2 can advantageously be formed by two extruded nozzles arranged in opposite directions, each nozzle forming monofilaments of one plane each, and the cross-section of the openings 10b formed in the first nozzle 8a being different from the openings 10b in the second nozzle 8b.
    In one embodiment, the sock 1 may comprise silver ions to produce an antibacterial effect. The sock 1 can thus be formed as an antibacterial. This is of particular benefit for various types of wounds and ulcers and in hospital and similar institutional settings. With the help of silver ions, sock 1 can also be formed to remove odor from sweat.
    In one embodiment, the tubular mesh structure 2 may be formed at one end closed so that the sock forms a bag-like mesh structure. Such a sock 1 may be formed, for example, by forming a tubular mesh structure 2 by an extrusion process, for example with two nozzles arranged in opposite directions, and closing the other end of the tubular mesh structure 2, for example by melting or welding.
    Figures 3a and 3b show schematically some socks 1 for patient use. In one embodiment, such as the embodiments of Figures 3a and 3b, the sock 1 may comprise at least one slider 5. The slider 30 5 may be made of a material having a lower coefficient of friction than the mesh 2. Hereby, the sock 1 can be formed from a selected region, i.e., the region of the slider 5, more sliding than the rest of the region of the sock 1, such as the area of the mesh structure 2. Depending on the embodiment, the slider 5 may comprise, for example, a film or mesh body. In one embodiment, a single slider 5 or a plurality of sliders 5 may be fitted to the mesh structure 2 by fixed welding. In another application7
    20175379 prh 28 -04- 2017 In one embodiment, one slider 5 or several sliders 5 can be fitted to the mesh structure 2 by seaming. In a third embodiment, a single slider 5 or a plurality of sliders 5 may be fitted to the mesh structure 2 by lamination. In other words, at least one slider 5 may be fixed to the mesh structure 5 immovably and irremovably, for example, by welding, seaming or laminating.
    In one embodiment, at least one slider 5 may be fitted to the sock 1 such that the slider 5 is positioned below the front of the foot when the sock is worn on the foot 6. In one embodiment, the mesh structure 2 may be 10 closed at one end and the slider 5 may be 2 with a closed end 7 than an open end thereof, whereby the slider 5 sits below the front of the foot when the sock is worn on the foot 6. Such a sock 1 is particularly advantageous in applications where the sock is required to be slippery on the one hand. This may be the case, for example, for persons whose movement of one or both feet, such as the ability to lift the foot when walking in the air, is restricted, allowing the person to slide his or her foot on the platform, for example by lifting the heel. In one embodiment, the at least one slider 5 may be in the sock 1 such that it extends substantially around the sock, preferably in the region 20 below the front of the foot when the sock is worn in the foot 6, such as in the embodiment of Figure 3b. The advantage of such a sock 1 is that it does not matter how or in which position the sock is worn.
    In the embodiment of Figure 3a, the sock 1 comprises two slides
    5. In another embodiment, however, the sock 1 may comprise only 25 sliders 5, e.g. 3a. Thus, in one embodiment, the slider fitted under the heel may comprise, for example, material 30 having a higher coefficient of friction than the slider 5 which can be fitted under the front of the foot.
    In one embodiment, the sock 1 comprises a separate elastic mouthpiece. For example, the flexible mouthpiece may be made of the same material as the mesh structure 2 or of different material. For example, such a flexible mouthpiece may facilitate the dressing of the sock 1 and help the sock to remain on the foot. Flexible
    20175379 prh 28 -04- 2017 The mouthpiece may be fitted to the open end of the mesh structure, for example, by solid welding.
    Figure 5 schematically illustrates a method of insertion of a sock 1 for patient use, such as one of the sock 1 shown in this specification. Such a sock 1 can be made by making the mesh structure 2 from a single-ingredient raw material granulate by an extrusion process. The mesh structure 2 can be manufactured, for example, by two nozzles 8a, 8b arranged in relation to one another, for example a nozzle arrangement 9 schematically illustrated in Figure 5a or 5b comprising such nozzles 8a, 8b. The nozzles 8a, 8b 10 may be pivotally disposed relative to one another. Preferably, the nozzles 8a, 8b may be arranged to rotate in opposite directions, for example, such that the inner nozzle 8a rotates clockwise and the outer nozzle 8b rotates anticlockwise, as shown in FIG. 6, schematically showing an inner nozzle 8a rotating anticlockwise. 8b is also circling until today. Each of the nozzles 8a, 8b may be circumferentially spaced from each other for apertures 10 for extrusion material. In other words, the nozzles 8a, 8b can then be rotated 52 in opposite directions to form a mesh structure 2. In other words, the extrusion material can be guided through the openings 10 as the nozzles 8a, 8b rotate in opposite directions to each other to form a mesh structure 2.
    In one embodiment, the mesh structure 2 may be fabricated by any of the methods described herein, wherein the mesh structure may be used for purposes other than making a sock for patient use.
    In various embodiments, the method may further comprise features and method steps disclosed in connection with embodiments of mesh structures 2 and socks 1, such as using different materials and shapes of apertures 10, fitting at least one slider 5 to mesh structure 2 and / or sock 1, and so on. Similarly, a method according to one of the embodiments shown may be used to make the disclosed mesh structures 2 and socks 30 1.
    Ordinary patient socks are typically knit stitches sewn together at the end, which tend to drain and remain poorly seated. The sock according to the present solution can be fitted, for example, on such a patient sock 35, whereby it holds the patient sock well but uncompressed and, on the other hand, acts as a non-slip motion when the patient is moving alone or assisted.
    Since the sock shown does not squeeze the foot, it is also suitable for use on sore and / or swollen feet. If necessary, the sock may also be readily customized to the patient's specific need, for example, by cutting open the mesh structure at a desired location, such as a wound or swelling, or, for example, adjusting a treatment device to pass through the sock.
    In some embodiments disclosed herein, the sock may also be washed so it can be used multiple times, i.e. it is non-disposable. This reduces the amount of waste generated.
    Although the mesh structure 2 and sock 1 disclosed herein are particularly well suited for patient use, it will be apparent to those skilled in the art that the mesh structure 2 and sock 1 and their embodiments may also be used for other purposes where a tubular mesh structure of at least transverse flexibility and affordability is required. As an example, embodiments with frictional properties may be used, in addition to patient use, for example in the elderly and, for example, in bathrooms, swimming pools and bathrooms to prevent slipping.
    It will be obvious to a person skilled in the art that as technology advances, the basic idea of the invention can be implemented in many different ways. The invention and its embodiments are thus not limited to the examples described above, but may vary within the scope of the claims.
