As shown in Figs. 1 to 4, the fracture patient cast 1 of the present invention is composed of a cast member 100 and a skin protector 200.

First, the cast member 100 is configured to give elasticity in the process of wrapping the skin protector 200 to be described later in configuring the present invention fracture patient cast (1) to impart compression fixing and breathability of the skin protector 200. .

On the other hand, the cast member 100 to be applied to the present invention is first composed of a first cylindrical member 110, the first cylindrical member 110 is composed of a woven chemical yarn, span yarn and rubber yarn mixed.

At this time, the first cylindrical member 110 is configured to form a mesh shape to form a plurality of diamond or honeycomb-shaped first vent hole 111 forming a gap of 3 ~ 5mm during tension and is configured to form a cylindrical shape in cross section.

That is, the first cylindrical member 110 is configured to have a resilient shape of the span yarn and rubber yarn while forming a net shape in which a plurality of first vent holes 111 are formed to enable communication of air.

In addition, the cast member 100 is composed of a second cylindrical member 120, the second cylindrical member 120 is composed of a woven chemical yarn, span yarn and rubber yarn mixed.

At this time, the second cylindrical member 120 is configured to form a mesh shape to form a plurality of diamond or honeycomb-shaped second vent hole 121 forming a gap of 3 ~ 5mm during tension and is configured to form a circular shape in cross section.

That is, the second cylindrical member 120 is configured to have elasticity by mixing span yarns and rubber yarns while forming a net shape in which a plurality of second vent holes 121 are formed to enable communication of air.

On the other hand, in the present invention, the first cylindrical member 110 and the second cylindrical member 120 is configured to be combined with each other to form one cast member 100, which is the first cylindrical member 110 is a second cylinder It is configured to be coupled to be indented and overlapped inside the member 120.

At this time, when the coupling is partially sewing in a double state overlapped so that the first vent hole 111 of the first cylindrical member 110 and the second vent hole 121 of the second cylindrical member 120 cross each other. Is fixed.

In addition, the first and second cylindrical members 110 and 120 overlapped as described above are configured to form an impregnated state by being impregnated or applied to the curable curing liquid, and are configured to have curability upon contact with moisture.

On the other hand, in the weaving of the first and second cylindrical members 110 and 120, the chemical company is configured to form the basis when mixed in the process of weaving the first and second cylindrical members 110 and 120, spanner and rubber The yarns are each configured to improve the elasticity and strength.

In this case, the ratio of the chemical yarn, spanner and rubber yarn to be mixed as described above will be most preferable to make each of the spanner and rubber yarn corresponding to 1/4 of the chemical yarn based on the chemical yarn.

This, for example, if more than 1/4 of the span and rubber yarn applied to the cast member 100 excessive elasticity may cause a decrease in pressure during the procedure, when applied to less than 1/4, the elasticity is reduced to the desired The treatment is difficult to shape the bar, by applying the span and rubber yarn to 1/4 to give elasticity through the span yarn and elasticity through the rubber yarn.

On the other hand, in the process of weaving the first and second cylindrical members 110 and 120, the main chemical company is not limited, but can be applied in various ways, for example, polyester, nylon, polyester, polypropylene, polyethylene It may be applied to at least one of terephthal, acrylic and ceramic.

In addition, in configuring each of the first and second cylindrical members 110 and 120, the thickness of each of the first and second cylindrical members 110 and 120 is configured to form a thickness of 400 to 500 denier in an overlapping state.

For example, if each thickness is applied to less than 200 denier, too thin and excessive elasticity and each of the strength is lowered can be easily broken during the procedure, if applied to more than 250 denier is too stretchy during the procedure In particular, when the first and second cylindrical members 110 and 120 overlap, the elasticity thereof is further lowered, which makes it difficult to perform elasticity.

Thus, by constructing each of the first and second cylindrical members 110 and 120 to 200 ~ 250 deniers, it is possible to maintain the elasticity and elasticity, and if these two overlapping configuration to form a thickness of 400 ~ 400 denier In addition, the strength is also improved, and the improvement of elasticity is the same as that of the elasticity in the case of elasticity of a plurality of rows compared to a single elastic band, and the improvement of the strength is more than a single sheet of paper. In the case of paper, the effect would be to reduce the tearing.

The skin protector 200 is formed in the cast member 1 for the fracture patient of the present invention is formed on the inner side of the cast member 100 is in contact with the skin during the cast process is configured to protect the skin and affected areas .

On the other hand, skin protector 200 to be applied in the present invention is composed of a high water-repellent yarn and a spanner is woven mixed.

At this time, the skin protector 200 is configured to form a mesh shape to form a plurality of diamond or honeycomb-shaped third vent hole 211 forming a gap of 3 ~ 5mm during tension and is configured to form a cylindrical shape in cross section.

And, the skin protector 200 is configured to further form a fluff 210 to enable compensation of the thickness on one surface thereof, that is, the outer surface contacting the cast member 100 when combined with the cast member 100, The fluff 210 absorbs the hydrocurable hardener impregnated in the cast member 100 during the procedure, thereby increasing the fixing force and preventing the hardener from being absorbed by the skin protector 200 and contacting the skin.

In addition, the fluff 210 prevents the saw blade of the cutting machine from penetrating to the skin protector 200 to cause skin trauma in the process of removing the cast as a compensation of the thickness.

In addition, the fluff 210 acts as a buffer to protect the affected part such that the shock is absorbed when an external shock is applied to the cast after the procedure.

That is, the skin protector 200 is configured to have a stretched shape in which the third vent hole 211 is formed so that the air can communicate with the cotton yarn mixed with the span yarn.

On the other hand, in constructing the skin protector 200 as described above, the high water-repellent yarn is configured to form the basis when mixed in the process of weaving and the span is configured to improve the elasticity, respectively.

At this time, the high water-repellent yarn to be applied to the present invention can be selected from pure cotton yarn or Gore-Tex yarn, because it is in direct contact with the skin of the patient, antibacterial treatment will be required.

In addition, the ratio of the high water-repellent yarn and the span yarn to be mixed as described above will be most preferable to make the span span 1/4 of the high water-repellent yarn based on the high water-repellent yarn.

This, for example, when applying the span more than 1/4 to the skin protector 200, excessive elasticity may act to reduce the adhesion during the procedure, when applied to less than 1/4, the elasticity is reduced to the desired shape The procedure will be difficult, by applying a span of 1/4 to the appropriate elasticity and elasticity can be obtained.

In addition, in configuring the skin protector 200, the thickness is most preferably configured to form 300 ~ 400 denier.

For example, if each thickness is applied to less than 300 denier, too thin, the cast member 100 when the pressure is increased when the skin compression force may be accompanied by discomfort due to the feeling of pressure in the procedure, applied to 400 denier or more Doing so will cause the cast to be too thick, reducing elasticity and causing discomfort to the patient's behavior.

Thus, by configuring the skin protector 200 to 300 ~ 400 denier it is possible to maintain the elasticity and elasticity, it is possible to minimize the discomfort of the patient during the procedure.
