Description

Functional cast

[0001] The present invention relates to a medical functional cast, and more particularly, to a functional cast comprising a fixed body formed in a body shape to surround a body part and an air pocket layer coupled to the inner side of the fixed body.

In general, gips or plaster casts are used for orthopedic treatments, which use quick-setting properties when water is added to a powder of calcined gypsum. Gibbs puts powdered gypsum on a bandage, dips it in warm water at 42-43 ° C with a vigor half before it is used, and winds it up to about 0.5 cm in the body's required area. After about 20 minutes, the bandage solidifies and supports the shape.

The currently used bandage casts should be wrapped to a certain thickness in order to fix the fracture site. However, this bandage type cast iron is buried in powdered gypsum, so it needs to be wrapped in heated water immediately before use, and then it is necessary to close the fracture area, and the weight of the gypsum is heavy, which is inconvenient for children and the elderly.

In addition, when loosening the cast, loosening the swelling of the fracture site causes a lot of space, which makes it difficult to fix the fracture site. If the cast is tightened too tightly, air will not penetrate into the cast and the pressure will be too strong to cause edema, Side effects.

Particularly, when using a bandage type cast, sometimes it is worn tightly when the cast is worn. At this time, it may cause compartment syndrome in which the nerve of the fascia is pressed too much and the supply of blood is reduced and muscle tissues are destroyed have.

When the compartment syndrome occurs, the initial symptom is pain in the affected part. Generally, the patient is regarded as the pain caused by the fracture, so that the condition may worsen and the compartment fascia may be worsened.

When these compartment syndromes occur, it is necessary to quickly release the Gibbs so that blood circulation can be improved, and it is inconvenient to go to the hospital quickly.

In order to solve such a problem, an easy-to-wear and easy-to-wear cast member has been invented. In Korean Patent Laid-Open No. 2003-0087610, " a cast member for a fracture or a disc patient and a casting method using the same, " in order to facilitate the wearing of a cast, a fracture or a disc, including an arm, a neck, an elbow, a knee, a waist, And a zipper is provided at both ends of the body of the casting so as to be firmly engaged with the affected part. Also, the cast member formed a plurality of ventilation holes for ventilation with the skin.

However, since the cast member needs to be manufactured for each size according to the thickness of each body part, it is difficult to find a size suitable for the patient, and the seam portion of the zipper is relatively weak, so that the cast may be loosened.

In order to solve the above-mentioned problems, the present invention uses a casting composed of a rigid fixed body formed in the shape of a body part and an air pocket layer coupled to the inner side of the fixed body, so that the casting can be easily and easily performed, There is no problem of pulleys, and air pockets are filled with air, so that they are fixed to the size of the body part, so that a functional cast which does not need various sizes is provided.

In addition, the present invention provides a functional cast capable of preventing side effects such as edema, tickling, and pressure ulcer caused by strong pressure because the air pocket layer is fixed to the body affected part by providing a plurality of ventilation holes.

According to an aspect of the present invention, there is provided a fixed body, comprising: a rigid fixed body formed in a shape of a body to cover a body part to be worn; And an air pocket layer coupled to the inside of the fixed frame; Wherein a plurality of air holes are formed in the fixed frame and the air pocket layer, and an air inlet port for injecting air into the air pocket layer is formed on the upper surface of the fixed pocket so as to communicate with the air pocket layer, Wherein the foamed synthetic resin is embedded in the foamed synthetic resin.

According to another preferred embodiment of the present invention, the fixed casting mold is a thermoplastic resin capable of changing the shape between 40 ° C and 80 ° C.

According to another preferred embodiment of the present invention, the percutaneous absorption preparation layer is attached to the inside of the air pocket layer in the present invention, the percutaneously absorbable preparation layer is applied on the skin, the top layer is coated with the first pharmacological agent Wherein the first and second pharmacological agents are selected from the group consisting of an analgesic agent, an anti-inflammatory agent, an anti-inflammatory agent, an anti-inflammatory agent, , And a cooling agent, or a mixture thereof.

The present invention has the following effects.

First, since a rigid fixture preformed in the shape of a body is wrapped around the body to be worn, it can be easily and easily worn, and there is no problem that the cast is loosened.

Second, since the air pocket layer is bonded to the inner side of the fixed frame, air is filled in the air pocket layer to fix the body part. Therefore, it is not necessary to fabricate several thickness sizes and the air of the fixed air pocket layer can be controlled, Side effects such as edema, tickling, and pressure ulcers can be prevented.

Third, a plurality of ventilation holes are formed in the fixed frame and the air pocket layer, so that sweat discharge is smooth and skin trouble can be prevented.

Fourth, since the air pocket layer serves as a skin protector, no separate skin protector is needed.

Fifth, because the percutaneous absorption preparation layer adheres to the inner part of the air pocket layer, it is effective for analgesic and inflammation, and has a cooling agent, which is effective to lower the fever caused by inflammation.

2 is a perspective view showing a state in which the functional cast of the present invention is worn.
3 is a cross-sectional view showing the percutaneous absorption preparation layer.

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

FIG. 1 is a sectional view showing a functional cast of the present invention, and FIG. 2 is a perspective view showing a state in which a functional cast of the present invention is worn.

1 and 2, the functional cast 1 of the present invention includes a rigid fixture 10 formed in the shape of a body portion S to surround a body portion S to be worn, And an air pocket layer 20 joined to the inside of the air pocket layer 20.

A plurality of ventilation holes 11 are formed in the fixed frame 10 and the air pocket layer 20. An air inlet 12 for injecting air into the air pocket layer 20 is formed on the upper surface of the fixed frame 10, Layer 20 as shown in FIG.

Conventionally, since a bandage type casting was generally used, there was a need to cover the casting portion to be worn. However, since the functional cast 1 is previously formed in the shape of the body part S to be worn, only the operation for fitting the functional cast is required, so that the functional cast 1 is not only shortened in time but also easy to perform.

The functional cast 1 can be manufactured in different sizes such as small size (S), medium size (M), large size (L), and the like.

Since the fixed casting mold 10 is made of a hard material, the functional casting mold 1 is worn with a casting material that is more spacious than the body turned casting mold S and the air inlet 12 on the upper face of the fixed casting mold 10 is opened Air is injected into the air pocket layer (20).

The functional cast 1 is pressed against the affected part S because the air layer that is not a hard and hard material fixes the affected part S in such a manner that the air pocket layer 20 is swollen and fixes the affected part S, It is possible to avoid side effects such as edema, tickling, and pressure ulcers.

The air pocket layer 20 is preferably made of polyurethane (PU) which is harmless to the human body and has good flexibility and excellent elasticity, but the material of the air pocket layer 20 is not limited to polyurethane.

The air inlet 12 may be provided in the form of a valve or a cap. The air inlet 12 may be a valve type in which the inlet port is opened when the inlet port is turned in one direction so that the inlet port can be easily opened and closed, and a port type in which the inlet port is closed when the port is turned in the other direction.

The air pocket layer 20 is filled with compressed foamed synthetic resin.

The foamed synthetic resin is preferably an expanded polypropylene (EPP) or an expanded polystyrene (EPS).

The foamed synthetic resin is in a compressed state in the air pocket layer 20, and when the air injection port 12 is opened, the foamed synthetic resin foam is foamed while the outside air enters, thereby fixing the functional cast 1 to the affected part.

A thermoplastic resin capable of changing the shape between 40 ° C and 80 ° C may be used as the fixing frame 10.

The thermoplastic resin may be selected from polyethylene (PE), polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC), and polyacryl.

The thermoplastic resin is a thermoplastic resin that is lightweight, excellent in heat resistance, and has good strength and can be molded because it changes from hard to soft when heated. Which is preferable for use.

In another embodiment, the fixture 10 may use a biodegradable polymer.

The biodegradable polymer is composed of polycaprolactone (PCL), polylactide (PLA), or a mixture thereof. Since the biodegradable polymer is decomposed by microorganisms, the biodegradable polymer can be classified as general waste immediately after unpacking. Can reduce the cost.

In another embodiment, the thermoplastic resin or the biodegradable polymer may be mixed with polyurethane to be used as the fixed frame 10.

Since the polyurethane has good elasticity, even if an impact is applied to the cast, the polyurethane absorbs the impact, and the impact is not transmitted to the affected part, resulting in less pain.

3 is a cross-sectional view showing the percutaneous absorption preparation layer.

A percutaneous absorption preparation layer (30) is attached to the inside of the air pocket layer (20).

3, the percutaneously absorbable preparation layer 30 includes a pressure-sensitive adhesive layer 31 for sticking on the skin, an absorbent resin layer 32 coated on the pressure-sensitive adhesive layer 31 and containing the first pharmacological agent, A microcapsule layer 33 coated on the absorbent resin layer 32 and containing a second pharmacological agent and a surface layer 34 applied on the microcapsule layer 33.

Since the pressure-sensitive adhesive layer 31 is directly attached to the skin, a material excellent in human toxicity stability should be used. Therefore, it is preferable to use a pressure-sensitive adhesive of natural or synthetic rubber type. Further, the rubber-based pressure-sensitive adhesive layer 31 is soft and soft, and is comfortable to wear when attached to the skin.

The absorbent resin used in the absorbent resin layer 32 absorbs perspiration secreted from the skin to improve the adhesive ability of the adhesive. In addition, the first pharmacological agent is uniformly dispersed in the absorbent resin layer 32 and provides a pharmacological effect to the affected part.

The microcapsule layer 33 is composed of an adhesive and microcapsules.

The pressure-sensitive adhesive acts as a binder for holding the microcapsule, and the microcapsule contains the second pharmacological agent, and when the first pharmacological ingredient is consumed, the pressure is applied to extrude the capsule to form the second pharmacological agent.

The microcapsule is composed of a wall material and a core material. Preferably, the core material is a secondary pharmacological agent, and the wall material is an acrylic resin which is weak in durability and breaks well.

The surface layer 34 may be a nonwoven fabric having a mesh structure for allowing air to flow well.

The primary and secondary pharmacological agents include any one of analgesics, anti-inflammatory agents, and cooling agents, or a mixture thereof.

The analgesic agent alleviates the pain of the affected part, and the anti-inflammatory agent and the cooling agent prevent inflammation from occurring.
