Definitions

  • the present invention relates, generally, to a stockinette used for the application of a splint for orthopedics for supporting an affected part of a patient suffering from a fracture or a sprain, and, more particularly, to an orthopedic water-repellent stockinette, in which polyester yarn, nylon yarn, cotton yarn, and/or elastic yarn are subjected to weaving and then water-repellent treatment using a water-repellent agent, unlike conventional stockinettes woven from cotton yarn.
  • the stockinette and cotton bandage should make it convenient to apply the splint for orthopedics, and should have a function of inhibiting the proliferation of bacteria, because a patient must wear them for one month or longer. Further, the stockinette and cotton bandage should have a thickness sufficient to provide a buffer function to protect the skin from the splint, consequently preventing secondary injuries, and also, should function to protect the skin from a splint cutter used upon the removal of a plaster cast. Furthermore, the stockinette and cotton bandage should assure comfort and ventilation upon application to a patient, to thus let sweat escape without letting water in.
  • the stockinette is made using hygroscopic cotton to absorb sweat, and the cotton bandage is also formed using hygroscopic cotton to absorb sweat.
  • a stockinette and cotton bandage are thick to protect the skin, and therefore, they have poor ventilation and do not dry well upon contact with moisture.
  • moisture may remain in the hygroscopic stockinette and cotton bandage, undesirably causing the proliferation of bacteria and the generation of offensive odors.
  • an object of the present invention is to provide an orthopedic water-repellent stockinette, in which polyester yarn, nylon yarn, cotton yarn, and/or elastic yarn are subjected to false twisting and circular knitting to increase the elasticity and thickness thereof, thus enhancing the buffer function between the skin and the splint, and in which a water-repellent treatment is conducted to thus let moisture escape without letting water in, thus preventing the proliferation of bacteria and the generation of offensive odors and blisters due to residual moisture, and minimizing complexity due to the separate application of the stockinette and the cotton bandage.
  • polyester yarn, nylon yarn, or cotton yarn having 50 deniers ⁇ 1100 deniers, may be subjected to false twisting and drawing, and then to circular knitting, along with elastic yarn having 20 deniers - 140 deniers to provide a good wearing feeling on the affected part, thus increasing the elasticity and thickness for a buffer function, unlike general stockinettes for orthopedics.
  • yarn upon circular knitting, yarn may be designed and woven to a texture having a ratio of yarn needles to which yarn is fed to empty needles to which yarn is not fed of 1 : 1 or 2:2 depending on the way that yarn is fed to the needle, thus manufacturing circular knitted fabric having a network structure having rhombic or circular meshes, resulting in increased ventilation.
  • water-repellent treatment may be conducted using a fluorine-based water- repellent agent that is harmless to the skin, followed by performing a drying process at 80°C ⁇ 130°C for 2 min ⁇ 5 min and then an adhesion process at 140°C ⁇ 200°C for 2 min ⁇ 5 min, thus completing a water-repellent product that lets sweat escape without letting water in.

  • the orthopedic water-repellent stockinette according to the present invention is manufactured in a manner such that yarn is designed and woven to realize a texture having a ratio of yarn needles to which yarn is fed to empty needles to which yarn is not fed of 1 : 1 or 2:2, depending on the way that yarn is fed to the needle, through circular knitting, thus manufacturing circular knitted fabric having a tubular shape.
  • the circular knitted fabric thus obtained has a network structure having rhombic or circular meshes, according to the above weaving type.
  • polyester yarn having 50 deniers ⁇ 1100 deniers is used through false twisting and drawing, along with elastic yarn having 20 deniers - 140 deniers.
  • nylon yarn or cotton yarn having the same deniers as 50 deniers - 1100 deniers may be used.
  • the embodiment of the present invention using the polyester yarn is described, and the same effects are realized whether nylon yarn or cotton yarn is used.
  • the thickness of the stockinette preferably ranges from 3 mm to 10 mm. If the thickness is below the lower limit, a buffer function is deteriorated. On the other hand, if the thickness exceeds the upper limit, it is difficult to perform a shaping process. Further, the weight of the stockinette preferably ranges from 10 g/in-m to 30 g/in-m. If the weight is less than the lower limit, the density is decreased and thus the buffer function is not exhibited. On the other hand, if the weight exceeds the upper limit, the patient suffers from discomfort due to the heaviness thereof.
  • the stockinette of the present invention may be used in a manner such that a single- layer product is formed into a double layer, as seen in FIG. 2, and may also be provided in the form of a 10 m roll to be used at a desired length after a cutting process is performed, as seen in FIG. 3.
  • the buffer effect relative to the splint is decreased and the ability to protect the skin from a splint cutter is also decreased. Further, when the stockinette is used in a triple layer or more, pressure is applied to the affected part, and formability is decreased.
  • the stockinette of the present invention may be provided to have a circular opening having a diameter of 2 inches, 3 inches, 4 inches, 5 inches, and 6 inches, and may also be provided in a roll form to be continuously usable, so that it is used at a desired length depending on the patient and affected part.
  • the stockinette of the present invention is subjected to water-repellent treatment using a fluorine-based water-repellent agent to thus let moisture escape without letting water in.
  • the fluorine-based water-repellent agent is applied in an amount of 1 wt% - 10 wt%, dried at 80°C ⁇ 130°C for a time ranging from 2 min ⁇ 5 min, and subsequently adhered at an increased temperature ranging from 140°C to 200°C for a time ranging from 2 min ⁇ 5 min. If the amount of the water-repellent agent is less then 1 wt%, water repellency is decreased and it becomes difficult to prevent the permeation of water.
  • the amount exceeds 10 wt%, the resultant coating film is separated and thus water repellency may be deteriorated. Further, when the drying and adhesion temperatures are lower than 80°C, water repellency may be decreased after 2-3 washings of the stockinette of the invention. On the other hand, when the temperature exceeds 200°C, the water-repellent agent and the fabric may be deformed.
  • the stockinette of the present invention is characterized in that both elastic yarn and any one selected from among polyester yarn, nylon yarn, and cotton yarn are subjected to doubling, false twisting and circular knitting to thus increase the elasticity and thickness for skin protection, without the need to use a conventional cotton bandage, and also in that water-repellent treatment is conducted to let moisture escape without letting water in, thereby preventing the proliferation of bacteria and the generation of severe offensive odors due to residual moisture.
  • Circular Knitted Fabric Yarn was designed and woven to a texture having a ratio of yarn needles to which yarn is fed to empty needles to which yarn is not fed of 1 : 1 or 2:2 depending on the way that yarn is fed to the needle, through circular knitting, thus obtaining a circular knitted fabric having a tubular shape and having a network structure having rhombic meshes.
  • the polyester yarn having 50 deniers ⁇ 1100 deniers was subjected to false twisting and drawing, and then weaving, along with elastic yarn having 20 deniers - 140 deniers, to thus exhibit good formability, resulting in a circular knitted fabric weighing 10 g/in-m ⁇ 30 g/in-m.
  • the products were compared in terms of dryness and buffer properties.
  • the dryness of products subjected or not subjected to water-repellent treatment was evaluated. Further, the washability of the products depending on the temperatures of water- repellent treatment and adhesion treatment was evaluated.
  • Residual Moisture Removal (%) [(product weight in water-dried product weight)/(product weight in water-initial product weight)] x 100
  • the initial moisture content after the immersion process in water was the lowest in products available from B and T subjected to water-repellent treatment.
  • the inventive product, subjected to water-repellent treatment had an initial moisture content of 68%, which was higher than those of products available from B and T but was considerably lower than those of conventional stockinette products.
  • the period of time required to completely dry the inventive product was determined to be 1.5 hours, which was much shorter than 5 hours for the products available from B and T. This is considered to be because the inventive product has a network structure and thus exhibits good ventilation, thus drying quickly even though initial moisture content is somewhat high.
  • the inventive product and conventional stockinette had a thickness of 10 mm, which is considered to be suitable for protecting the affected part from the splint.
  • the inventive product had higher elasticity than any of the other products, and thereby was seen to efficiently protect the affected part from external impact.

Abstract

L'invention concerne un jersey tubulaire utilisé dans l'application d'une gouttière orthopédique pour supporter une partie affectée d'un patient souffrant d'une fracture ou d'une entorse. À la différence des jerseys tubulaires traditionnels formés par tissage de fils de coton, dans le jersey tubulaire hydrofuge orthopédique de l'invention, un fil polyester, un fil nylon, un fil de coton et/ou un fil élastique sont tissés et sont ensuite soumis à un traitement hydrofuge au moyen d'un agent hydrofuge. Alors que les jerseys tubulaires et les bandages en coton sont ensuite appliqués sous des plâtres, le jersey tubulaire de l'invention est caractérisé en ce que le fil polyester, le fil nylon, le fil de coton et/ou le fil élastique sont soumis à une fausse torsion et à un tricotage circulaire de façon à accroître l'élasticité et l'épaisseur pour protéger la peau, sans avoir besoin d'utiliser en plus un bandage en coton, et également en ce que le traitement hydrofuge est effectué pour laisser s'échapper l'humidité sans laisser d'eau à l'intérieur, ce qui empêche la prolifération des bactéries et la génération d'odeurs extrêmement incommodantes due à l'humidité résiduelle.
