Abstract

An orthopedic water-repellent stockinette and a method of manufacturing the same are provided to improve an impact absorbing characteristic using a nylon thread and to achieve a water-repellent characteristic using an ultra water-repellent agent. A twisted and drawn nylon thread is prepared. An elasticity and a thickness of the nylon thread are increased through a circular weaving process. An impact absorbing degree of the nylon thread is also improved through refining and drying processes so as to protect the skin. Therefore, a cotton bandage needs not to be supplementarily used. In addition, the nylon thread is provided with water discharge and water-repellent functions through a water-repellent treatment using a water-repellent agent. A high molecular acrylic fluorine-group water-repellent agent can be employed as the water-repellent agent. The orthopedic water-repellent stockinette prevents bacterial propagation and bad smell caused by residual moisture.

Description

ORTHOPEDIC WATER-REPELLENT STOCKINETTE AND METHOD OF MANUFACTURING THE SAME}

The present invention relates to a tubular bandage used during orthopedic splint surgery to support the affected areas, such as fractures and sprains, and more specifically, after weaving nylon yarns as a material unlike the tubular bandages used by weaving cotton yarn And to increase the shock absorption through the drying process, and relates to a water-repellent tubular bandage for orthopedic surgery using a water-repellent agent and a method of manufacturing the same.

When conventional orthopedic splints are treated, it is common to wrap a tubular bandage using plain cotton and a cotton bandage made of cotton on it, and then wet the plaster bandage or synthetic casting tape with water, and then wound and fix the wound around the affected part. .

These bandages and cotton bandages have been used to protect the skin from splints used for fractures of joints and bones, and these products are being developed in various forms to protect the skin with the development of synthetic casting tapes.

The coronal bandage and cotton bandage should facilitate the procedure of orthopedic splint, and the patient should be worn for more than 1 month, so the growth of bacteria should be suppressed. It should also have sufficient cushioning to protect the skin from the splint, be thick enough to prevent secondary injuries, and protect the skin from the splint removal saw when removing the splint. In addition, coronary and cotton bandages should ensure comfort and breathability when worn by the patient to prevent sweat release and moisture.

The tubular bandage and cotton bandage has been used a lot as a material for protecting the skin from the splint for a long time, but there was a conventional need to re-add the cotton bandage on the wound after the tubular bandage.

In addition, the tubular bandage used a hygroscopic cotton to absorb sweat, cotton-based cotton bandages also used a hygroscopic cotton to absorb sweat. These tubular bandages and cotton bandages had to be thickened in order to protect the skin, so there was a problem that the ventilation was not good and the drying was not performed well when moisture was reached. In particular, during the treatment of the splint, since the splint is used to soak in water, residual moisture remains in the hygroscopic tubular and cotton bandages, causing the growth of bacteria and odor.

In order to compensate for this, Gore Inc. of the United States has invented a product in the form of a tape using a Gore-tex material, a two-waterproof Teflon film, and has developed a product that can prevent sweat and prevent moisture during the treatment of splints.

In addition, Korea's T & L Co., Ltd. has developed a product of the same principle using a moisture-permeable urethane film using the Gore's principle.

However, the above products have a disadvantage that it is difficult to alleviate the impact from the splint because the film and the skin protective layer is thin, and when dismantling with a splint cutter, a separate protective tape must be additionally treated.

In addition, when moisture enters the film, the product is made of a film, which is not ventilated at all, and has to be completely vaporized. Because of this, there was a problem that the sores and odors and itching of the affected area is caused.

In addition, although a product that has been water-repellent treated with a general water repellent agent in a starkinnet such as general acrylic, polyester, and polypropylene has been developed, the product is thin and elastic, and it is not strong, so it does not absorb shock from the splint, thereby There was an uncomfortable disadvantage of using the cotton bandage again.

In order to solve this problem, the applicant of the present application can sufficiently buffer the protection of the skin from the splint with only a tubular bandage without wearing a separate cotton bandage. To provide an orthopedic water-repellent tubular bandage that can be done and conveniently performed.

The present invention has been proposed in view of the problems described above, and its object is to make the material of tubular bandages of nylon yarn treated with flammable and stretched material and to increase elasticity and thickness through circular knitting, and also circular knitting weaving. It is possible to enhance the buffering effect of skin and splint through refining and drying the tubular bandage, and to secure the discharge of water and water repellent function through water repellent treatment to prevent the propagation of bacteria, odor and sores due to residual moisture. It is to provide a water-repellent tubular bandage for orthopedic surgery to minimize the hassle of having to perform the separate tubular bandage and cotton bandage separately.

The present invention for achieving the above object

Unlike general orthopedic tubular bandages, 50 ~ 1100 denier nylon yarns are used and weaved and stretched at the same time to weave them into circular knitting pieces. At the same time to create a circular knitted fabric structure to increase the elasticity and thickness to buffer.

In addition, according to the present invention, the ratio of the needle to be threaded and the needle not to be threaded is designed to be 1: 1 or 2: 2 tissue according to the shape of hanging the needle when weaving the circular knitting, and as a result, the circular knitting is woven. The shape of the hole made through the rhombus shape or circular shape to form a mesh structure to increase the ventilation.

In addition, the present invention is subjected to the scouring process boiled in water of 70 ~ 95 ℃ in order to increase the buffering effect of the woven tubular bandages as described above, after which the combusted yarn shrinks and the tubular bandages as a result Thicker. This thickened yarn can increase the cushioning effect of the splint and skin, thicken enough to eliminate the need for a separate cotton bandage, and also increase the shock absorption.

In addition, according to the characteristics of the present invention by coating a fluorine-based polymer super water-repellent agent that does not irritate the skin at all, dried for 2 to 5 minutes at a temperature condition of 80 ~ 130 ℃, raise the temperature at 140 ~ 200 ℃ By fixing it for 2 ~ 5 minutes to make the product water repellent, it prevents moisture and releases sweat quickly.

According to the present invention, two roles of a tubular bandage and a cotton bandage that can protect the affected part from the splint can be performed at a time, thereby eliminating the trouble of having to perform the existing two times, and a bandage and a cotton bandage. It has excellent buffering effect, which is an essential requirement, but also has good water discharge and water repellent effect, and it is useful to prevent the soaking caused by residual moisture.

In particular, the present invention provides the usefulness that can act as a buffer while resolving the growth of bacteria and severe odor and itching due to the residual moisture that was a problem of the conventional tubular bandage.

1 is a state of use of orthopedic water-repellent tubular bandage according to an embodiment of the present invention.

Figure 2 is a view showing a perspective view of an orthopedic repellent tubular bandage according to the present invention.

Hereinafter, with reference to the accompanying drawings, the present invention will be described in detail.

As shown in Figures 1 and 2, the orthopedic water-repellent tubular bandage according to the present invention is 1: 1 or 2: ratio of the needle for hanging the thread and the non-hanging needle according to the shape of the thread hanging on the needle. It is designed to be composed of two ratios of tissue and weave, but weave circular weavers to form a tubular shape, and the shape of the hole made through circular weaves shows a rhombus shape or a circular shape. Structure.

This mesh structure facilitates ventilation and helps to release sweat and moisture.

In the present invention, 50-1100 denier nylon yarns were used by false twist and drawing (延伸), and 20 to 140 denier elastic yarns were used together.

In this case, when cotton yarn, polyester yarn, polypropylene yarn or the like is used instead of the nylon yarn, the wear resistance and durability are low, and thus the skin protection performance against the impact of the affected part from the splint is reduced during long-term use.

Here, when the nylon yarn is 50 denier or less, the buffering action is significantly reduced, and when using more than 1100 denier, the ventilation is difficult to form, so it becomes difficult to form the affected part, and if the elastic yarn is not spliced or the elastic yarn of 20 denier or less is used, the bent part Stable fit in the stomach will fall and if you use more than 140 denier pressure on the affected area will inhibit blood flow.

Woven tubular circular knitted fabric is subjected to a glossing process boiled in water at 70-95 ° C. in order to increase the thickness, followed by shrinkage of the flammable stretched nylon yarn during drying. Can make thickened tubular bandages. At this time, if you want to increase the thickness without going through the refining process, more than 1100 denier yarn should be used in this case, as described above, the ventilation is inferior.

The thickness of the tubular bandage is preferably 3mm ~ 10mm, when the thinner than this, the buffering effect is reduced, and when thicker than this, the molding becomes difficult. In addition, the weight of the coronary bandage is preferably 10g / in.m ~ 30g / in.m. If the lighter than this, the density is lowered, the buffering effect is lost, and if the weight is heavier than this, the patient feels uncomfortable due to the weight of the coronal bandage.

This tubular bandage of the present invention will be used to make two layers of a product as shown in FIG.

At this time, the coronary bandage has a weakening effect from the splint and the skin protection ability from the splint cutting saw when one ply is used. Also, when three or more plies are used, the tubular bandage has the disadvantage of high compression and poor formability.

Coronary bandage of the present invention may be provided in a variety of sizes 2inch, 3inch, 4inch, 5inch, 6inch by the size of the circular piece, so that the user to use by size depending on the surgical site, if the affected area is large, provide two or more sizes. This is preferred.

In the present invention, the fluorine-based polymer super water repellent is applied to the tubular bandage for quick discharge of water and external blockage of water, and the fluorine-based polymer super water repellent is coated at a weight ratio of 1-10% to 80-130 ° C. After drying for 2 to 5 minutes at the temperature conditions were treated to be fixed for 2 to 5 minutes at a temperature of 140 ~ 200 ℃ to raise the temperature. In this case, when the weight ratio is less than 1%, the water repellent effect is difficult to prevent moisture, and when the coating is more than 10%, the coating film is separated to have the disadvantage of lowering the water repellent effect. In addition, when the drying and fixing treatment temperature is lower than 80 ℃ water repellent effect may be lowered when washing the tubular bandage of the present invention 2 to 3 times, when treated at 200 ℃ or more may be modified water repellent and fabric.

As described above, the present invention by incorporating the elastic yarn to the nylon yarn improved durability through the twisting and stretching to perform a circular knitting weave in the tubular form and to increase the elasticity and thickness through the refining process and drying process of the tubular circular knitting fabric It protects the skin and eliminates the hassle of additionally using cotton bandage, and ensures water discharge and water repellent function through water repellent treatment, thereby reproducing bacteria and severe odor due to residual moisture. It is to prevent.

Thus, the present invention will be described in detail based on the following examples, but the present invention is not limited to the examples.

Example 1

1. Circular knitting weave: The circular knitting fabric is designed by weaving with a ratio of 1: 1 or 2: 2 ratio between the needle to be threaded and the needle not to thread depending on the shape of the needle. To form a tubular shape woven into the circular knitting, the shape of the hole made through the circular knitting weave the rhombus shape is made of a network structure.

In addition, in order to maintain a thickness of 3mm ~ 10mm was used by twisting and stretching 50 ~ 1100 denier nylon yarn, weaving 20 to 140 denier elastic yarn was woven to improve the formability. In addition, the woven tubular circular woven fabric in this way is boiled in water of 70 ~ 95 ℃ refining process, and then through the drying process to induce the shrinkage of the combustible yarn to thicken the thickness enough. As a result, a circular knitting structure of 10 g / (in · m) to 30 g / (in · m) was completed.

2. Water-repellent treatment: Fluoride-based super water-repellent agent was used to fabricate circular knitted fabric, and the fluorine-based polymer super water-repellent agent was diluted to 10% and coated so that the ratio of water-repellent agent was 8: 2 weight ratio. After drying for 2 to 5 minutes at a temperature condition of 90 ~ 130 ℃, the temperature was raised to be treated for 2 to 5 minutes to fix under a temperature condition of 140 ~ 180 ℃ to complete the water-repellent tubular bandage of the present invention.

3. Comparison of products

The drying and buffering properties of the products were compared according to the type of products, and the drying properties of the water-repellent tubular bandages of the present invention and the products without the water-repellent treatment were compared. In addition, the washability according to the water-repellent treatment and fixing treatment temperature of the present invention was compared.

The method using a general coronary band and cotton bandage, and the US T-shirt Teflon film-type skin protection pad and Korea T's urethane-type skin protection pads were compared.

(Test Example 1)

In order to compare the dryness of each product, 4 inch products were wound on the model foot and splint treatment was performed by the method specified in each product's manual. After the products were completely dried, the initial weight was measured except for the weight of the model foot. Since the product was soaked in water for 10 seconds and then taken out and dried in an oven at 70 ° C. while weighing and recording the weight by time, and recording it as a percentage to measure the drying time.

The weight of the product was measured by time and the amount of moisture remaining in the product was recorded as a percentage.

(Comparative 1) Results of dryness test between the existing product and the present invention

As shown in (Comparative 1), the initial moisture content after immersion in water is the lowest as the products of the company B and T that is waterproof, the water is blocked, the present invention is water-treated at 68% initial The moisture content is higher than that of B company or T company, but the water content is much smaller than that of the conventional tubular bandage. However, in the case of the present invention, the drying time is 1 hour and 30 minutes, and it can be seen that the drying time is much faster than the 5 hours of the B company and the T company. To indicate.

(Test Example 2)

In order to compare the product-specific buffering properties, the 4-inch product was treated in two layers, and the buffering property was measured by measuring the force according to the thickness change by the compression test of the tensile compression tester.

(Comparative 2) Result of force change according to thickness change

As shown in (Comparative 1), it can be seen that the thickness of the present invention and the thickness of the existing tubular bandage is 10 mm, which is good for protecting the affected part from splints. In particular, the present invention has the best elasticity among the comparative products. It shows that the affected part can be well protected from external shock.

(Test Example 3)

In order to measure the washability of the water repellent according to the fixing temperature, after impregnating 3% of the superhydrophobic polymer-type super water repellent, drying and fixing of the water repellent were performed at the respective temperatures for 8 minutes, and then washed several times to check the water repellency. .

(Comparative 3) Washing Result According to Fixing Temperature

        Condition Dry and fix at 80 ° C for 8 minutes Dry and fix for 8 minutes at 100 ℃ Dry and fix at 150 ℃ for 8 minutes Dry and fix for 8 minutes at 180 ℃ Washing count 3rd time Good Good Good Color badness occurs 10th Water repellency Good Good 15th Water repellency Good 20 times Good

As shown in (Comparative 3), the drying under the conditions of 150 ℃ shows the best washability, and when drying and fixing at 80 ℃ or less it can be seen that the washability gradually becomes worse, more than 180 ℃ It can be seen that when the drying and fixing in the change of physical properties of the water repellent and the change of nylon yarn.
