Description

Medical Splint {SPLINT}

The present invention relates to a medical splint, and more particularly, to a medical splint that is light in strength and superior in strength and easy to use by using an upper and lower limb nonwoven fabric.

Generally, in the case of fractures or cracked bones, splints are used to join the cracked parts or to fix the fractured parts. As a method widely used for this purpose, the method using a gypsum bandage is mentioned.

The gypsum cast wraps the bandage coated with gypsum on the fracture site and the gypsum material hardens to support the fracture site.

However, such gypsum casts require a considerable amount of time and effort to be treated, which is cumbersome to handle and heavy. In addition, there was a problem that the X-ray transmittance is poor. Therefore, various splints have been developed to solve this problem.

As one of these splints, there are two layers of two or more non-woven fabrics, each of which has an edge bonded by means of adhesion, that is, an antibacterial skin (endothelium or lower limb) to which an antimicrobial agent is added, and an outer nonwoven fabric (skin or upper limb) of the antibacterial skin In addition, there is a medical splint made of a support that contains a hydraulic resin between the two layers to form a supporting force upon contact with moisture.

According to the conventional medical splint, water passes quickly through the antimicrobial skin to the hardened skin, and a vent is formed in the hardened skin to increase ventilation and prevent itching or other side effects, and at the same time to adhere to the affected area without wrinkles. Can be.

However, in such a conventional splint, curable resin flows out through a vent at the time of use, and is cured after the procedure. The cured resin that flows out like this may be in contact with the skin of the patient, causing a wound, and inconvenient during the procedure, such as contacting the operator's hand during the procedure.

Therefore, a medical splint has good strength as a support, yet has good ventilation, and a curable splint excellent in the comfort to the patient is required without the curable resin flowing out during the procedure.

An object of the present invention is to solve the above problems, to provide a medical splint having excellent strength and rigidity, good ventilation, and excellent fit to a patient without the curable resin flowing out during the procedure.

1: medical splint

2: outer layer

3: inner layer

4: knitted fabric

5: double sided tape

6: hydrophilic pad

In order to achieve the above object, the medical splint according to the present invention is a knitted or nonwoven fabric of glass fiber or polyester fiber coated with a water-curable resin reacted with polyisocyanate, polyetherdiol and polyethertriol as main ingredients. (Hereinafter referred to as a 'woven fabric'), an outer layer made of a nonwoven fabric having good air and moisture permeability, and a nonwoven fabric disposed on the side in contact with the support and touching the patient's skin and thicker than the thickness of the outer layer. A medical splint comprising an inner layer and a double-sided tape disposed at edges of the outer layer and the inner layer and not in contact with the support.

In addition, the medical splint according to the present invention is characterized in that a hydrophilic pad is further disposed between the support and the outer layer and between the support and the inner layer, respectively.

In addition, the hydrophilic pad is characterized in that consisting of hydrophilic polyester or hydrophilic pulp.

According to the medical splint according to the present invention as described above, the outer layer and the inner layer are made of a nonwoven fabric having good air and moisture permeability. For this reason, the water absorption and discharge which react with the said water-curable resin to harden a support body are quick.

Further, in the medical splint according to the present invention, since a hydrophilic pad is provided between the outer layer, the support, and the inner layer, and the support, the hydrocurable resin is blocked by the hydrophilic pad, so that the hydroponic resin is used as in the prior art. The chemical resin does not flow out and touch the patient's skin.

In addition, the inner layer is made of a nonwoven fabric thicker than the outer layer, giving a soft touch, it is possible to obtain a comfortable fit.

In addition, since the outer layer and the inner layer are separated from the water-curable resin by the hydrophilic pad, air permeability is good.

EXAMPLE

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

1 is a cross-sectional view showing an embodiment of a medical splint according to the present invention, Figure 2 is a cross-sectional perspective view schematically showing an exploded state of the medical splint according to the present invention.

In the drawings, reference numeral 4 denotes a knitted fabric. The medical splint requires a certain strength and rigidity. For this purpose, the knitted fabric 4 is composed of a plurality of layers, for example, 8 ply in this embodiment.

This knitted fabric 4 is coated with a hydrocurable resin. The water-curable resins in the present examples are polyisocyanates, polyetherdiols and polyethertriols. The coating amount of the water-curable resin is, for example, 126 g of polyisocyanate, 91 g of polyetherdiol, and 13 g of polyethertriol based on the total weight of 700 g of the medical splint.

The inner layer 3 also consists of a nonwoven fabric of hydrophobic polypropylene, for example. This nonwoven fabric uses air and moisture permeable and is clean and non-irritating. In addition, the nonwoven fabric is tasteless and odorless which does not contain foreign substances.

The outer layer 2 is made of, for example, a non-woven fabric of a spunlace treated with hydrophobic treatment, while the thickness of the inner layer 3 is set to be thicker than the thickness of the outer layer 2. For example, with respect to the total weight of medical splint 700 g, the nonwoven fabric of the outer layer is 40 g, 1.2 mm, and the nonwoven fabric of the inner layer is 150 g, 4.2 mm. Thereby, the medical splint according to the present invention has good air permeability due to the relatively thin nonwoven fabric of the outer layer 2, and a good wearing feeling can be obtained during the procedure by the relatively thick nonwoven fabric of the inner layer 3.

In the conventional medical splint, when the nonwoven fabric is used on the side of the patient's skin, the curable resin flows out during the procedure, penetrates between the nonwoven fabric, and touches the skin of the patient, causing pain.

However, in the medical splint according to the present invention, since the hydrocurable resin is blocked by the hydrophilic pad 6 in the nonwoven fabric forming the outer layer 2 and the inner layer 3, the curable resin flows out during the procedure. Never touch the skin.

The hydrophilic pad 6 may be made of polyester having a thickness of 0.3 mm. In addition, the hydrophilic pad 6 may be made of a hydrophilic pulp having a thickness of 0.2 mm. It is preferable to use the same kind of thing for the same medical splint, without using two types of such hydrophilic pads simultaneously.

In addition, due to the use of the hydrophilic pad, it is possible to constantly supply water to the water-curable resin during use.

Moreover, the double-sided tape 5 is arrange | positioned between the said outer layer 2 and the inner layer 3, The said double-sided tape 5 may use a conventional thing. In addition, the double-sided tape is disposed so as not to contact the knitted fabric 4 to which the water-curable resin is applied, and also to not come into contact with the hydrophilic pad 6.

It looks at the manufacturing process of the medical splint of the above configuration.

First, the nonwoven fabric is woven through a loom (not shown). Then, in order to apply to the knitted fabric 4, polyisocyanate, polyetherdiol and polyethertriol are added and gasketed in advance. Thereafter, the additive is applied to the knitted fabric 4.

Then, after overlapping the knitted fabric coated with the water-curable resin in eight layers, a hydrophilic pad is provided between the eight-layer knit fabric and the outer layer nonwoven fabric, and the nonwoven fabric and the inner layer nonwoven fabric. Then, the non-woven fabric of the inner layer 3 is covered with the non-woven fabric of the inner layer 3, and the outer surface 2 is covered with the non-woven fabric of the outer layer 2, and the outer layer 2 and the inner layer 3 are covered with the double-sided tape 5. Bond it. This is completed by cutting the medical splint prepared to a certain standard.

In using the finished medical splint, first of all, after opening the package of the product for the treatment area, it is immediately immersed in water at room temperature and squeezed once or twice. Then, remove excess water from the product and fix the inner layer with an elastic bandage towards the treatment area. Then, when the mold is molded by hand, the curable resin is cured to form a solid support, which is stably fixed.

As described above, the medical splint according to the present invention is light and excellent in strength and simple in operation.

Since the medical splint of the present invention is made of a nonwoven fabric having good permeability of air and moisture in the outer layer and the inner layer, the water absorbing and discharging to react with the water-curable resin to harden the support is fast.

In addition, according to the medical splint according to the present invention, since a hydrophilic pad is provided between the nonwoven fabric of the outer layer and the knitted fabric, and particularly between the nonwoven fabric of the inner layer and the knitted fabric, the hydrocurable resin flows out and penetrates into the nonwoven fabric so as to penetrate the patient. It does not touch the skin and cause pain or discomfort to the patient.

In addition, the inner layer is made of a nonwoven fabric thicker than the outer layer, giving a soft touch, it is possible to obtain a comfortable fit. In addition, since the outer layer and the inner layer are separated from the water-curable resin by the hydrophilic pad, air permeability is good.
