Description

Orthopedic Splint {SPLINT FOR ORTHOPEDICE}

The present invention relates to an orthopedic splint structure for supporting affected areas such as fractures and sprains, and more particularly, a skin contact layer and a mesh form of a polypropylene nonwoven fabric on a glass fiber or polyester support coated with a moisture curing resin. It relates to a splint structure using the epidermal layer of.

In general, conventional orthopedic splints have been used for gypsum bandages and synthetic bandages for body fractures and muscle injuries or sprains, and recently fixed methods have been developed through various methods such as synthetic splints. Has been.

The structure of the splint is made of a hardened synthetic resin as a hardening material to easily use it, and the hardening material is applied to various fibers to be used as a support, and it can be encapsulated in a pad and treated at one time. This product can be used.

The materials used in the orthopedic splint should be flexible in order to easily shape the curved area and maintain sufficient mechanical strength to prevent secondary injury.

In addition, while maintaining a uniform curing time during molding, the working time should be appropriate, and after the procedure should be well dried, there should be no secondary injury due to the sores of the affected part.

In the case of the gypsum bandage has been used a lot as a splint material for a long time, the working time and curing time during the procedure has a disadvantage that the product is heavy, and has a low strength compared to the weight.

In order to compensate for this, a product using a glass fiber, a polyester nonwoven fabric or a polyester knitted fabric, etc. by applying a water-curable resin as a support was developed.

However, in the case of the water-curable synthetic resin sprint, the synthetic resin may flow out to the pad layer to press the skin of the patient, causing pain and causing injury.

In addition, in order to solve this problem, the pad is a water-repellent product is used as a pad, but this has the disadvantage that the shape is distorted after the procedure in the affected area due to the uncomfortable workability to interfere with the absorption of water.

In addition, there are products that use a hydrophilic pad only on the epidermal layer of the pad and a water repellent pad on the skin contact layer. However, due to the characteristics of the hydrophilic pad, the moisture is not well removed and the drying time is long. There is a problem that causes sores.

In addition, since the hydrophilic agent is used to maintain hydrophilicity, the product has a disadvantage in that the hydrophilicity is lowered over time.

The present invention has been proposed in view of the problems described above, and its purpose is to use a double-lasel fabric in the form of a mesh for the epidermal layer and a water-repellent nonwoven fabric for the skin contact layer to facilitate the penetration and removal of moisture and Hardening is even and drying time is fast to provide an orthopedic splint configured to resolve the sores of the affected area.

According to a feature of the present invention for achieving the above object, to support the affected area wrapped around the affected area, the skin contact layer in contact with the skin and the epidermal layer exposed to the outside and the contact layer and the epidermal layer is laminated to maintain a specific shape In the conventional orthopedic splint structure consisting of a support layer, the skin contact layer is a non-woven fabric and knitted fabric having a hydrophobic and water-repellent of 100 ~ 400g / m ² , the support layer is composed of a water-curable resin and a support The skin layer is provided with an orthopedic splint using a selected one of polyester, polypropylene, and nylon in the form of a mesh of 20-1000 mesh but maintaining a weight of 100-400 g / m ² .

In addition, according to another feature of the present invention, the epidermal layer is provided with an orthopedic splint, characterized in that the use of a knitted fabric of a Raschel structure as a kind of warp knitting.

In addition, according to another feature of the present invention, the outer shell layer knitted fabric is a double-lasel structure consisting of a mono yarn laminated between the double laselle fabric, the thickness of the outer skin layer orthopedic, characterized in that configured to have a 0.5mm ~ 5mm Dragon splints are provided.

In addition, according to another feature of the present invention, the raschel fabric yarn of the epidermal layer is provided with orthopedic splint, characterized in that configured to have a thickness of 1000 ~ 10,000 denier.

Hereinafter, described in detail with reference to the accompanying drawings orthopedic splint of the present invention.

1 is an exploded perspective view showing an orthopedic splint according to an embodiment of the present invention, Figure 2 is a cross-sectional view showing an orthopedic splint of the present invention, Figure 3 is an epidermal layer that is the main part of the orthopedic splint of the present invention It is sectional drawing shown.

The orthopedic splint of the present invention, as shown, uses a hydrophobic polypropylene nonwoven fabric in the skin contact layer (1) to prevent the water-curable resin from directly contacting the skin, and water dries quickly from the skin during the product procedure. As the support layer 2, fibers coated with a hydrocurable resin are used.

As the skin layer 3, a polyester double mesh knitted with a Raschel group is used to facilitate the penetration and extraction of water.

In more detail, the skin contact layer 1 uses a hydrophobic polypropylene nonwoven fabric produced by needle punching and uses a product having a weight of 100 to 400 g.

By using a nonwoven fabric produced by needle punching, the skin can be softly touched and the affected part can be protected from the support layer 2.

In addition, the nonwoven fabric uses hydrophobicity to protect the water penetrating into the epidermal layer 3 from entering the skin.

In addition, the nonwoven fabric may cause pain in the affected part due to the compression of the support layer 2 when the weight is low, and when the weight is high, it is difficult to form the affected part.

In the case of the support layer (2) is used that the water-curable resin is applied to the support, and the support is used by overlapping 6 ~ 9 layers of 3 ~ 8g / in. M glass fiber fabric or polyester (Polyester) fiber fabric or 300 You may use -1000 g of polyester or polypropylene nonwoven fabric.

When the weight of the fiber or nonwoven fabric is small, the strength as a support cannot be maintained, and the higher the weight, the more difficult the molding, the heavy the product, and the poor breathability.

Hydrocurable resin of the support layer (2) uses a polyurethane (Polyurethane) prepolymer (Polyurethane), the viscosity is 25,000 ~ 60,000cps and higher than this resin is not completely applied to the support to drop the strength, if lower than this flow of resin This may lead to the flow of resin out of the nonwoven fabric. This hydrocurable resin is suitable for a resin composed of about 10 to 15% NCO%. If the NCO% is higher than this, there is a risk of secondary injury due to the high exothermic temperature when reacting with water, and the viscosity of the resin may be lowered. In addition, if the NCO% is lower than this may reduce storage stability during storage and the viscosity may be difficult to apply to the support.

In the case of the epidermal layer (3), the drying time of the moisture was shortened by using a double raschel fabric of a mesh type (20-1000 mesh) to facilitate the penetration and extraction of water. The mesh fabric is a double-lasel fabric of the dual structure as shown in Figure 3 to prevent the resin from flowing to the skin layer (3).

The double-lasel fabric is a woven monolayer (mono) (b) between the two raschel fabrics (a) (c) that is a network structure collected by a raschel group, the raschel fabric (a) (c) is To maintain the flow and ventilation of water, the mono yarn (b) is to give a gap to the laselle fabric (a) (c) yarn to prevent the flow of the resin and to ensure a smooth ventilation.

When the resin flows to the epidermal layer 3, the surface of the product may be roughened due to the resin after curing of the product, which may damage other skin parts.

When there is no mono yarn (b) between the laselle fabrics (a) and (b), the water-curable resin flows to the epidermal layer 3 so that the resin may get on the hands during the procedure.

In order to prevent the flow of the resin may be used to overlap a plurality of mesh-type fabric, it is preferable that the thickness of the mesh yarn is about 1000denier ~ 10,000denier.

As described above, the present invention solved the existing problem by using a skin-like epidermal layer 3, thereby relieving the sores of the affected area and the discomfort of the patient. In addition, even curing time and fast treatment to provide the operator's convenience.

Such 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.

Epidermal layer (3): The epidermal layer (3) is made of a double raschel machine in the form of a net, which is divided into three layers as a kind of warp knitting.

Figure 3 (a) and (c) is a Raschel (raschel) structure (b) used a mono yarn, the thickness was made of 2mm, 300g / m ² weight product was used.

Wrap it up.

The product is packaged in aluminum packaging to complete the product.

Comparison of products1

The hygroscopicity, drying time and resin flowability of the products were compared according to the type of skin layer (3) of the product as below.As a comparative example, OptiMasprint of Join Enterprise Co., Ltd. and Nemoasprint of T & L Co., Ltd. Yulim GR-2001 was used as a comparative product.

Join Enterprise Co., Ltd.'s Optima Sprint skin layer 3 was made of hydrophobic polypropylene nonwoven fabric, and T & L's Nemoa Sprint was made of hydrophilic polypropylene nonwoven fabric. GR-2001 Sprint of Yulim Co., Ltd. is a product using water-repellent polyester spunlace nonwoven fabric.

(Test Example 1)

In order to compare the hygroscopicity of the epidermal layer 3, 5 ㅧ 45inch of product was immersed in water for 10 seconds, and the setting time of the center of the product was measured by the method of ASTM F1536-95. The same comparison test was carried out after the product was stored in an oven for 30 days.

(Comparative 1) General Products

As shown in (Comparative 1), it can be seen that the product using the hydrophilic nonwoven fabric and the present invention has excellent water permeability, and in the case of the sprint using the hydrophilic polypropylene nonwoven fabric shown in (Comparative 2), time-dependent change in heat It appears that there is a drawback to exhibit water repellency.

It can be seen that the product of the present invention does not cause changes over time for heat, and thus physical properties are continuously maintained.

Experimental Example 2

In order to check the drying time after soaking the product in water, the product was compared by the following drying test method.

(Test method of dryness of the product)

1. Measure the initial weight of the product of 5 ㅧ 45inch.

2. Completely open the epidermal layer (3) so that the product has enough water, and soak the product in water for 10 seconds.

3. Remove the product from the water, dry it with a dry towel, and weigh it.

4. Fold the product in half and dry it in a 70 ° C oven.

5. Weigh the product over time and record the percentage of moisture remaining in the product.

Initial moisture content% =

Residual moisture% =

     Skin layer material drying time Product Optimasprint GR-2001 Square print Reticulated double cell (polyester) Hydrophobic Polypropylene Nonwovens Water Repellent Polyester Spunlace Hydrophilic Polypropylene Nonwovens Initial moisture content 11.9% 25.3% 27.4% 20.5% Residual moisture over time 5 minutes 43% 19% 12% 31% 10 minutes 70% 31% 22% 49% 15 minutes 86% 41% 29% 57% 20 minutes 95% 50% 37% 70% 25 minutes 100% 57% 45% 78% 30 minutes 65% 52% 85% 35 minutes 70% 57% 90% 40 minutes 75% 61% 95% 45 minutes 79% 65% 98% 50 minutes 82% 70% 100% 55 minutes 85% 73% 60 minutes 89% 77% 80 minutes 99% 88% 100 minutes 100% 95% 120 minutes 100%

As shown in the above table, it can be seen that the initial water content is very low because of good water drainage phenomenon due to the network structure of the designed product.

In addition, since the initial moisture content is low, the drying time is shortened to remove the phenomenon of water accumulation, and it can be seen that it can play a role of preventing the sores of the affected part due to moisture.

(Test Example 3)

In order to compare the phenomenon in which the water-curable resin flows out into the epidermal layer 3, a resin flow test was performed as follows.

1. Apply the water-curable resin to the polyester support layer 2 (knit) in a 1: 1 ratio.

2. The skin contact layer 1 uses the same nonwoven fabric (320 g hydrophobic polypropylene nonwoven fabric).

3. The skin layer 3 is covered with a double cell, a hydrophobic polypropylene nonwoven fabric, a water repellent polyester spanlace, and a hydrophilic polypropylene nonwoven fabric, respectively, to prepare the product in a general manufacturing method.

4. In a state of packing in a wrapping paper, let the skin layer (3) face down in the oven at 70 ° C, and then check the state that the resin flows out of the skin layer (3) every hour.

Skin layer (3) material Reticulated double cell (polyester) Hydrophobic Polypropylene Nonwovens Water Repellent Polyester Spunlace Hydrophilic Polypropylene Nonwovens The time the resin flowed out 168 hours (good for seven days) 120 hours (residual flow phenomenon after 5 days) 168 hours (good for 7 days) Resin flow phenomenon on skin layer 3 after 3 days

As shown in the above table, it can be seen that the hydrophilic polypropylene nonwoven fabric exhibits the most resin flow phenomenon, and in the case of the designed product, it can be seen that the resin flow phenomenon is prevented due to the voids of the mono yarn.

As described above, the present invention not only facilitates the penetration of water, which is an essential requirement of orthopedic splints, but also shortens the drying time, which is essential for orthopedic splints using a water-curable resin. There is an advantage. It also has the advantage of reducing the risk of secondary injury by supplementing the resin flow phenomenon, which is a disadvantage of hydrophilic products.
