Description

{{Medical splint}

The present invention relates to a medical splint, wherein a polypropylene stretch yarn is knitted from a Double Raschel warp knitting machine so as to have a predetermined width in two layers, while a double-layer knitted fabric rim and an intermediate portion are integrally connected So that the outer surface exposed to the outside is in close contact with the inner surface contacting with the body. Thus, it is made as a medical splint. It is easy to manufacture consistently in the double ratsel warp knitting machine, the edge of the rim is clean and the width is constant, The knitted fabrics of the knitted fabric are excellent in cushioning feeling and excellent in stretchability in the length, width and diagonal direction so as to wrap the body three-dimensionally but without folding parts, thereby providing convenience to both the practitioner and the patient.

In general, orthopedic surgeons use splints to fix the body's fracture site. This splint, when applied to the elbow or knee, can be brought into contact with the body's skin without wrinkles on the folds Elasticity, that is, flexibility.

As is known from Patent Documents 1 to 4, in conventional orthopedic splints, various synthetic resin yarns such as polyester yarn are used instead of glass fibers which have been used for a long time, In the conventional laminated splices, it is necessary to carry out an operation of laminating in multiple stages in the process of manufacturing the same, and it is necessary to integrate them by using a sewing thread again, A finishing work for finishing the parts neatly is required, which complicates the manufacturing process and requires a considerable degree of skill.

In addition, in the conventional laminated splint, in order to give a sufficient cushioning feeling, the number of fabric layers to be laminated has to be increased, and in the process of lamination in multiple, the elasticity is lowered and the adhesiveness to the three-dimensional body surface is deteriorated. The patient may feel a sense of foreign body as well as the patient should pay considerable effort to eliminate the wrinkles.

Patent Literature 5 discloses a polypropylene stretch yarn in which a cylindrical splint fabric is woven in a circular knitting machine and a cylindrical splint fabric is flattened and sewed with a plurality of sewing yarns along the length direction, Which is made of a splint having a predetermined width and a length so that the outer surface exposed to the body and the inner surface contacting the body closely come into close contact with each other.

On the other hand, since the splint of Patent Document 5 is knitted while pressed by the presser foot in the process of sewing with a sewing thread in a separate process after knitting into a cylindrical shape in a circular knitting machine, the width of the fabric having high stretchability in the longitudinal direction and width and diagonal direction is irregularly deformed There is a disadvantage in that the standard of the sewing machine is not constant and the manufacturing cost is increased due to the addition of the sewing sewing process.

The object of the present invention is to solve the above-mentioned problems, and it is an object of the present invention to provide a method of manufacturing a laminated glass fiberglass which is formed by laminating a splice made of conventional glass fiber, polyester yarn or nonwoven fabric, The present invention is to provide a new type of splint for medical use that can solve the disadvantages of a splint type splint, which is simple in manufacturing process, is eco-friendly, and excellent in flexibility, and can provide convenience to both patients and practitioners.

In order to attain the above object, the present invention provides a warp knitted fabric comprising a warp yarn in which a polypropylene stretch yarn is warp knitted in a double-ratse warp knitting machine in two layers at a predetermined width, The medical splint having a predetermined width and a predetermined length so that the outer surface exposed to the outside and the inner surface contacting the body come into close contact with each other.

The medical splint according to the present invention uses a plurality of warp yarns in a double Raschel warp knitting machine to form a loop in an oblique direction so that a double-ply knitted fabric is manufactured to have a predetermined width, while a double-ply knitted fabric rim And the inner surface of the two-ply knitted fabric is integrally connected along the longitudinal direction so as to closely contact the outer surface exposed to the outside and the inner surface contacting the body. The manufacturing process is simple and the loop size of the connecting yarn and the warp yarn So that even if the knitted fabric is connected by the connecting yarn, the width is constantly produced. Since it is made of two layers, the cushion feeling is excellent, and the stretchability in the length, width and diagonal direction is maintained. But there is no folding part, so there is a practical effect that can provide convenience to both the practitioner and the patient.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3 show a state of a medical splint according to an embodiment of the present invention.

As shown in the drawing, the medical splint 1 according to the present embodiment has a warp yarn (2: a white yarn in a photograph) in which 20 to 40 yarns of a 200 to 300 denier polypropylene stretch yarn are folded, (10, 20) of the double-layered knitted fabric of a predetermined width while sewing the middle portion with the interconnect yarns (3,4) And is made to have a predetermined width and length so that the inner surface contacting the body is closely contacted.

For the sake of convenience, the warp yarn and the connecting yarn are knitted using yarns of different colors, but it is needless to say that the yarn of the same color may be used as a warp yarn and a connecting yarn.

In the medical splint 1 according to the present embodiment, loops formed by the warp yarns 2 are knitted while knitting in a longitudinal direction, which causes a large number of knitting needles rising in the bed of the warp knitting machine to rise simultaneously, The body passes through the yarn, and the knitting needle is then threaded, and then descends simultaneously to form a loop.

The splint fabric knitted in this embodiment is a warp knitting method in which a warp yarn is formed by connecting a warp yarn having a number equal to or more than the number of needles to a nose in the direction of making a nose in the longitudinal direction, Use a double Raschel knitting machine.

The connecting yarns 3 and 4 are also connected to each other by hooking their noses between the double yarn knitting yarns 10 and 20 in the Double Raschel warping machine so that the rim portion is in the same state as when knitted by a circular knitting machine, And the intermediate portion is bound to the front and rear knitted fabrics 10 and 20 in a state where the two rows of the connecting yarns 4 are spaced apart in parallel at a predetermined interval, And the front and rear knitted fabrics 10 and 20 are integrally joined to each other so that the front and rear knitted fabrics 10 and 20 do not extend. The space between the fabrics 10 and 20 forms a space in which the medicine for hardening the splint can be impregnated and stored.

In other words, the splint fabric according to the embodiment of the present invention actually maintains the same condition as the double splice even though it has a double layer, so it has excellent flexibility which can be flexed along the curved surface of the human body while maintaining a high volume feeling .

When the two-ply knitted fabrics 10, 20 are integrated by using the connecting yarns 3, 4 as in the present embodiment, flexibility can be improved when compared with the single-ply splint fabric by the circular knitting machine of Patent Document 5 As a matter of course, since the space S is formed between the two-ply knitted fabrics 10 and 20, the performance for absorbing the chemicals for hardening the splints is improved, and a clean edge condition is maintained, thereby improving the merchantability.

In addition, since the splint of the present embodiment is knitted so as to be integrally formed at the same time by using the warp yarns 2 and the connecting yarns 3, 4 in the double-ratse warp knitting machine, not only the post-process (sewing) , A separate sewing thread is used to sew the sewn portion in the longitudinal direction is shrunk, the remaining portion remains unchanged, irregular shape does not occur, and when the tension of the sewing thread is not constant, It is advantageous to produce with a constant thickness and a constant width.

The splint (1) shown in the drawing is cut into different lengths according to the use purpose, that is, the split splint before being cut.

In addition, in the present invention, the splint 1 can be manufactured in various widths. If necessary, the splint 1 can be knitted into two or more layers and integrated, It is needless to say that the knitting density may be varied.

In the present embodiment, the intermediate connecting yarns 3 are arranged in two rows. However, the present invention is not limited to this, and the connecting yarns may be arranged in two or more rows depending on the width of the splitting yarns, Of course.
