Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an attachment including a medical orthosis, a rehabilitation orthosis, etc., which is used for the purpose of reducing or recovering a functional disorder by externally supporting human body parts such as limbs and trunk of the human body. With regard to this, in particular, by providing the mounted product with a molding function, the mounted product can be mounted according to the mounting site, and the defective mounting can be eliminated.

[0002]

2. Description of the Related Art In recent years, with the spread of rehabilitation medicine, supporting the skeletal muscle system of the human body from the outside of the extremities and trunk,
Various wearable products have been developed for the purpose of reducing and recovering functional disorders. The wearing article for such an application is particularly called a brace. The orthosis is broadly classified into fixing, supporting, straightening, unloading, walking, standing and towing orthosis depending on the purpose of use.

Basically, it is desired that such an orthosis can be used in a state where it is fitted to a portion to which a human body is attached and which does not cause discomfort or pain during attachment. Therefore, the necessary measurements are made to create the brace. However, the measurement is performed by measuring the dimension from the outside with a measure, and it is not possible to sufficiently read the uneven shape of the human body of the mounting portion as compared with the measurement. Therefore, with an orthosis created based only on measurements, it is not possible to wear it according to the subtle unevenness of the mounting part, and when it is worn, some rubbing occurs, making it difficult to obtain a perfect wearing feeling, There are many cases where it is a pain for the wearer.

Further, in terms of a comfortable wearing feeling, it is not limited to the brace used for the above medical purposes and the like, and the same applies to various clothes such as underwear, clothes, socks, gloves and hats that are used daily. Is. Furthermore, footwear such as shoes can also be mentioned. The shape of the foot is not only its size,
There are large individual differences such as the height of the instep, and originally,
Shoes tailored to each individual foot form are preferred. However, at present, it is often the case that ready-made shoes are used in time. The problem of hallux valgus, which has become a problem in recent years, is also a physical disorder caused by wearing shoes that do not fit the foot shape or wearing narrow shoes.

Further, it has been proposed to use a cover suitable for the shape of the product as a protective cover for the product other than the one used for the human body, so as to perform appropriate protection. Taking away from the idea of simply covering the product, by creating a cover tailored to the details of the product, it is possible to accurately prevent unnecessary movement of the product in the cover and ensure its protection. Proposed.

[0006]

As described above, in many products including clothing apparel, it is thought that ideally, it is ideal that the device can be worn in a form that suits the wearer. In order to realize such an ideal mounted state, it is required to manufacture a product by taking a mold rather than a case where only measuring is performed.

However, under the present circumstances, a technique that can be easily used on a daily basis without any particular knowledge has not been developed so far, and ideally, a tailor-made method is preferred. As we know, most of the time, we use ready-made clothing, footwear, and other accessories to make do. Since it is troublesome to take a mold and the cost is high, it is often the case that a ready-made product is used in time.

[0008] Such a point is often not a big problem because it does not easily fit the body of a healthy person and does not feel comfortable to wear, but in the case of a brace or the like used by a disabled person, the problem is There are serious problems such as deterioration of the degree, delay of therapeutic effects such as recovery and correction, and unsatisfaction with wearing feeling, making it unsuitable for long-term wearing.

On the other hand, even if the mold can be easily made,
If the production cost of the attached product based on it, including molding, becomes high, the attached product cannot be used sufficiently. The production based on the individual molds having different shapes is not originally adapted to the mass production method, and the mass production effect in terms of cost cannot be obtained.

Therefore, the inventor of the present invention wondered if it would be possible to develop a technique in which the sample can be mounted as it is. If it can be easily molded, and can be mounted as it is in the molded state or with a little modification, it is possible to shorten various steps from molding to product production in the prior art. We thought that it would be possible to easily and inexpensively provide a fitting that fits the fitting part at a reasonable price.

[0011] In the conventional molding, for example, in the formation of medical equipment, a molding technique mainly using gypsum or a plaster bandage has been the mainstream. The gypsum bandage is required to be properly wrapped while the gypsum is not dried, with an appropriate wrapping force without excessively pressing the soft tissue of the affected area while the gypsum is softening. Normally, it is necessary to complete the work in about 5 minutes, and in order to perform good mold sampling,
Considerable skill is required.

[0012] In the actual medical field, a qualified prosthetic orthotist must be engaged in such a mold according to a doctor's prescription, and it is not easy to do things without knowledge. For that reason, although prosthetic hands, artificial legs, etc. are inevitably used for making prosthetic limbs, orthoses used for orthodontic treatment often do not take the form, and have standardized various sizes. In many cases, it was possible to select the dimensions suitable for oneself from the ready-made sheath. Originally, such sheaths need to be sampled in a state suitable for the user.

The object of the present invention is to make various types of wearable articles including an orthosis and the like, which can be easily sampled according to the wearable object and can be worn in that state, without the conventional troublesome molding. To do so.

[0014]

The present invention is formed of a stretchable base material on which a thermoplastic material such as a thermoplastic resin is laminated, and a mounting target is sampled and sampled in a flow state of the thermoplastic material. It is a mounted article having a molding function, which is characterized by being hardened in a molded state so that it can be mounted. The substrate is cloth.

The wearing article is a brace that is used for the purpose of reducing or recovering a functional disorder by supporting a human body part such as a limb or a trunk of a human body. The attached article is characterized in that it is formed into an inner socket that is attached to a stump portion on the human body side when attaching an artificial limb or the like. The wearing article is a clothing article. The wearing article is footwear such as shoes. The thermoplastic resin has a fluidity of 0.5 to 1000 at the time of casting.
It is characterized by being Pa · S.

The "wearable article" referred to in the present specification means not only a thing worn by a person, but also an article to which a non-human animal, a living thing such as a plant, or an inanimate object is worn. . For example, when a person is to be worn, clothing, footwear, hats, etc. to be worn are assumed, and these include orthoses used for medical purposes. As a non-living object to be attached, for example, use of a protective cover for various products such as electric products, an exterior, a storage case, a cushioning material for transportation, and the like can be considered.

Further, "thermoplastic" as used herein
The term "plasticizer" used to impart plasticity to resins and the like does not mean "plasticizer", but means a material having thermoplasticity, for example, synthetic rubber or thermoplastic resin. .

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1) In Embodiment 1, a case will be described in which an attached product having a molding function of the present invention is applied to an inner socket used when attaching a prosthesis. FIG. 1 is a cross-sectional view showing a mounted state of a prosthesis. FIG. 2 (A) is a perspective view showing an inner socket as a mounting product having a molding function of the present invention, and FIG. 2 (B) is a partial cross-sectional view showing a laminated state of a base material and a thermoplastic material, (C) is a perspective view showing an inner core used for producing the inner socket shown in (A).

First, the mounting condition of the artificial leg will be described.
As shown in FIG. 1, the artificial leg is first attached to the stump 1 of the patient.
A bag for putting the stump 10 as the expandable sheath 11 is put on 0. After that, the inner socket 12 which is modeled according to the unevenness of the stump 10 is mounted. An elastic sheath 13 (also called a soft insert cover) formed in a bag shape is further worn on the mounted inner socket 12.

In such a state, the inner socket 12 fitted with the expansion sheath 13 is fitted and mounted in the outer socket 14a of the artificial leg 14 so that the artificial leg 1
4 is attached. As the prosthesis 14, various conventionally known structures can be used. In the case shown in FIG. 1, an off-the-shelf cosmetic foam 14b made of a foam material and the cosmetic foam 14 are used.
It is composed of a lower leg portion 14c and an outer socket 14a supported by a rod-shaped supporting portion 14d which is erected on the lower leg portion 14c.

The inner socket 12 is conventionally made mainly of silicone rubber and has a bad slipperiness. When mounting the stump 10, the stump 10 is caught by the inner socket 12, and it is difficult to directly and smoothly mount the inner socket 12 on the stump 10. Therefore, the inner socket 12 is mounted while wearing the elastic sheath 11 of a stump bag such as socks.

Similarly, when mounting the inner socket 12 on the outer socket 14a, the inner rubber socket 12 made of silicone rubber has a large friction and can be smoothly inserted into the outer socket 14a molded of acrylic or polyester. Therefore, as described above, the expandable sheath 13 also called a soft insert cover is put on and then mounted on the outer socket 14a.

The inner socket 12 of the conventional structure is formed by cutting a foamed sheet material and adhering it to a male mold which is raised from a female mold which is fitted to the stump portion 10 of the patient, or a silicone rubber is thinly applied to the male mold. It was created by molding, such as dipping. Further, since the inner socket 12 is made of silicon rubber and is thin, it may be broken during mounting.

The inner socket 15 of the present invention shown in FIG. 2A is the inner socket 12 of the above-mentioned conventional structure.
It solves various problems of the above. As shown in FIG. 2 (B), the inner socket 15 of the present invention is made of a molding material formed by laminating a thermoplastic material 17 on a base material 16.

In the fluidized state of the thermoplastic material 17, the stump portion is directly pressed to take a mold, or the molding material is pressed from the stump portion 10 to a male mold based on a female mold. By taking a mold, it is cured in that state and used as it is. That is, it is not something which is made by dipping silicone rubber in a male mold or connecting foamed sheets, and it can be made very easily.

The inner socket 15 of the present invention is shown in FIG.
As shown in (A), an opening 15a for inserting the stump 10 is provided at one end so that the stump 10 of the lower limb can be mounted.
It is formed in the shape of a substantially straight tube bag with the other end closed. The inner socket 15 of the present invention is, as an actual product form,
For example, the bag shape may be classified into several types of the assumed shape of the stump portion 10 and configured as a standard product according to each type. In addition, even if the shape is the same, it is sufficient to prepare several pieces having different sizes in accordance with the difference between men and women and the general mode of the wearer such as an adult or a child.

As shown in FIG. 2 (A), the inner socket 15 of the present invention comprises a thermoplastic material 17 having two stretchable cloths 16a and 16b formed in the same bag shape as a base material 16. The thermoplastic resin 17a is sandwiched between them. Such a configuration is shown in the sectional view of FIG.

Two cloths 16 sandwiching the thermoplastic resin 17a
The a and 16b may be formed in a straight sock shape by circular knitting, for example. For example, spandex may be formed into a densest loop pile knitting in which a filament yarn (melting point of 255 ° C. or higher) such as polyester or nylon is combined with a base yarn.

In the form of a bag in which the thermoplastic resin 17a is sandwiched, the center surface of the product of the inner cloth 16b and the outer cloth 1
It is preferable to use at least a loop surface of loop knitting on the outer surface of 6a. The loop surface is used in the above range because the thermoplastic resin 17a is used to make it in a moldable state.
Is required to be fluidized by heating, but the purpose is to prevent heat conduction to some extent by the heat of the thermoplastic resin 17a in the fluidized state so that the inner socket 15 does not become difficult to handle. .

As the thermoplastic material 17 used together with the base material 16, thermoplastic synthetic rubber or thermoplastic resin can be used. Examples of the thermoplastic resin include olefin resins, ethylene-propylene resins, butyl resins, urethane resins, and the like. Examples of the olefin resin include polyethylene, polypropylene, ethylene vinyl acetate copolymer resin (EVA) and the like.

Examples of synthetic rubber include styrene-butadiene-styrene (SBS), styrene-isoprene-styrene (SIS), styrene-ethylene-butylene-styrene (SEBS), styrene-ethylene-propylene-styrene (SEPS) and the like. To be

Further, a cross-linking type thermoplastic resin may be used. For example, cross-linked polystyrene resin, polyolefin resin, polyurethane resin, acrylic resin,
Polyester resin, polyamide resin, etc., or silane cross-linked synthetic rubber, etc. are also conceivable. Examples of the crosslinking method include a chemical reaction type, a thermosetting type, a UV irradiation type, an electron beam irradiation type and a high frequency irradiation type.

When the above thermoplastic resin or synthetic rubber is used, talc for adjusting viscosity and other compounding agents may be appropriately used in consideration of fluidity at the time of casting.

For example, the following thermoplastic resins are considered. SEPS (Septon 2043: manufactured by Kuraray) 250 parts by weight Tackifying resin (ESCOLETS 5320: manufactured by Tonex) 200 parts by weight Process oil (KP100: manufactured by Idemitsu Kosan) 275 parts by weight Wax (NP505: manufactured by Mitsui Chemicals) 100 parts by weight Wax (paraffin 155 °: manufactured by Nippon Seiro Co., Ltd.) 75 parts by weight APAO (UT2535: manufactured by Ube Lexen) 100 parts by weight A thermoplastic resin having such a composition has a melt viscosity of 3500 mP.
The softening point (R & B method) was 135 ° C. At the time of use, even at about 80 ° C., it exhibits sufficient moldability and has sufficient elasticity after curing. Therefore, the inner socket 15 can be easily attached to the stump 10 with the same feeling as wearing socks.

The inventor of the present invention has sought fluidity that facilitates molding by using various thermoplastic resins.
It was confirmed that 0.5 to 1000 Pa · S (Pascal · second) is preferable. When the fluidity is less than 0.5 Pa · S, the thermoplastic resin laminated on the base material flows and it is difficult to take a mold. Further, when the pressure exceeds 1000 Pa · S, the thermoplastic resin is in a softened state but has poor fluidity, and the thermoplastic resin does not spread along the slightly delicate uneven surface at the time of molding, Is hard to do. In the state where there is no fluidity and it is simply softened, the precision mold casting intended by the present invention cannot be performed. More preferably, 2 to 200 Pa
It is S.

In the above measurement, Brookfield viscometer Thermosel system rotor No. 28 20r / m
It was used.

The thermoplastic resin 17a and the cloths 16a and 16b as the base material 16 are compounded as follows. That is, the plate-shaped core 18 shown in FIG. 2C is inserted into the bag-shaped inner cloth 16b to adjust the shape, and in that state, it is dipped in the liquefied thermoplastic resin. . The dipping is performed up to the lower side of the welt 15b of the inner socket 15 shown in FIG.
After curing, cover the outer fabric and put 150-160 in the high temperature bath.
Expose at about 10 minutes. In this way, the outer cloth 16a can be heat-bonded to the thermoplastic resin 17a laminated on the inner cloth 16b.

After heat-sealing, the welt 15b portions of the two cloths 16a and 16b are lock-sewn and fixed to one cloth. The shape is, for example, 10 to 15 cm in width and 1 c in thickness.
It is formed in about m and the maximum circumference is 50-60 at the time of molding at the site.
It is formed so that it can be extended to about cm. As product forms, products of various lengths may be prepared.

The bag-shaped inner socket 15 thus formed as shown in FIG. 2A is used as follows. The inner socket 15 of the present invention having an appropriate size is selected according to the size of the stump of the patient to whom the inner socket 15 is attached.

The selected inner socket 15 is put in the field, for example, in a high temperature tank and heated until the thermoplastic resin 17a falls within the range of fluidity. For example, when the thermoplastic resin 17a having the above composition is used, 140 ° C.
Heat for about 15 minutes. With the thermoplastic resin 17a in a fluidized state so that it can be molded, the thermoplastic resin 17a is put on the stump 10 of the patient and lightly pressed so as to conform to the irregularities of the stump 10 and the inner socket 15 molds.

After about 5 minutes in the molded state, the thermoplastic resin 17a is cooled and hardened in a state in which the molded state is maintained.
The cured product can be mounted and used as it is as the inner socket 15.

In the above description, the case where the inner socket 15 having the molding function of the present invention is directly pressed against the stump portion 10 for molding is explained. It may be pressed against an existing male mold to take a mold.

In the inner socket 15 of the present invention, as described above, while the thermoplastic resin 17a is being fluidized, the molding is performed along the stump portion 10 or the uneven portion such as the male mold. When correction is required during or after the mold is cast, the repaired part that has been once hardened is locally blown with hot air again with a heat dryer, etc., and the corresponding part is fluidized, and the corresponding male part is fluidized. The mold can be reapplied by hitting the mold part or the stump.

Although such a correction process cannot be performed by the conventional method of forming the inner socket 12 made of silicon rubber,
The inner socket 15 of the present invention has such a correction function because it uses a molding material. This is a common feature of the mounted articles such as the inner socket 15 of the present invention which uses a molding material formed by laminating the thermoplastic material 17 such as the thermoplastic resin 17a on the base material 16.

In the case where the correction portion extends over the entire area, the once molded inner socket may be placed in the high temperature tank again for a predetermined time to fluidize the thermoplastic resin 17a entirely, and then the molding is performed again. . Also, by following the procedure of such re-correction, the inner socket 15 that is no longer needed
However, the thermoplastic resin 17a can be reused as an inner socket of another stump portion by bringing the thermoplastic resin 17a into a fluid state again. Such reuse is also effective from the viewpoint of resource saving.

Further, the thermoplastic resin 17a described above is
It has the same rubber elasticity as silicone rubber, but is tougher and does not break than silicone rubber. This is a thermoplastic resin 17
a The original strength, but the thermoplastic resin 17a is cloth 16a
It is also because it is covered with the base material 16 such as.

Further, in the inner socket 15 of the present invention, the base material 16 such as the cloths 16a and 16b is exposed on the inner surface and the outer surface thereof.
Even when the stump portion is mounted on 5, it is possible to smoothly mount it without causing friction and getting caught. Similarly, when the inner socket 15 is attached to the outer socket 14a, unlike the case where silicon rubber is used, unnecessary friction does not occur, and the outer socket 14a can be smoothly attached.

Therefore, the inner socket 15 of the present invention
When using, the mounting of the expandable sheaths 11 and 13 required for mounting the silicon rubber inner socket 12 having the conventional configuration can be omitted.

As the inner socket 12 of the conventional construction, one formed by joining foamed sheet materials as described above is known, but the inner socket 15 of the present invention which can be directly sampled from the stump 10. Can perform delicate casting,
The feeling of wearing is extremely favorable.

The stump 10 is actually a portion having extremely complicated and delicate irregularities such as irregularities of bones and swelling of muscles, and in such a state, a delicate mold capable of supporting the weight evenly. Otherwise, a non-uniform load will be applied to the stump 10, and it will be unbearable for long-term mounting. However, in the inner socket 15 of the present invention, since a molding material capable of performing delicate molding can be used as it is for mounting, inconvenience in this respect is unlikely to occur.

In the above description, the inner socket used for the artificial limb has been described, but it goes without saying that it can be applied to the inner socket used when the stump portion such as the arm is attached to the artificial hand. Furthermore, the structure of the inner socket described above of the present invention can be applied as long as it is a mounted article having a function and a function substantially similar to those of the inner socket.

The inner socket used in the above description is, as an alias, a soft socket, a soft inserter,
It may also be called a soft insert or soft liner.

(Embodiment 2) In the present embodiment, a fixing fitting for use in treatment of a fracture or the like will be described. FIG. 3 (A) is a cylindrical mounting attachment 19 which is an example of an attachment having the molding function of the present invention.
FIG. 4B is a perspective view showing the structure, and FIG.

As shown in FIG. 3A, in the fixing attachment 19 of the present invention, two elastic cloths 16c and 16d having the same shape formed in a tubular shape are used as the base material 16 and the cloth 16 is used.
A thermoplastic resin 17a is laminated on c and 16d. As shown in the cross-sectional view of FIG. 3B, the two cloths 16c, 16
The thermoplastic resin 17a is sandwiched between d and formed. The two cloths 16c and 16d are formed by circular knitting into a tubular shape. Spandex is used as a base yarn in combination with polyester or nylon yarns, and the inner fabric surface of the product is knitted into a fine loop pile.

The two edge portions 19a and 19b of the two cloths 16c and 16d are knitted only with the bandex yarn, and the thermoplastic resin 1 laminated on the cloth 16c on the inner side is used.
When 7a is covered with the outer cloth 16d, it is fixed to one piece of cloth by lock stitching. As the thermoplastic resin 17a that can be used in such a configuration, the same one as in the first embodiment can be used.

More specifically, for example, a thermoplastic resin having the following composition can be used. Ethylene vinyl acetate copolymer resin 25 parts by weight (Evaflex 220: manufactured by Mitsui DuPont Polychemical Co., Ltd.) Adhesive imparting resin (Arcon P100: manufactured by Arakawa Chemical Industry Co., Ltd.) 15 parts by weight wax (HNP-9: manufactured by Nippon Seiro Co., Ltd.) 35 Parts by weight Talc (average particle size: 1.75 μm) 25 parts by weight polyester fiber (thickness 0.5D, length 3 mm) 0.2 parts by weight A thermoplastic resin having such a composition has a melt viscosity of 4200 mP.
a · s / 180 ° C. (Brookfield viscometer Thermosel system rotor No. 27 20 r / m), and the softening point (R & B method) was 81 ° C. In use, by heating until the fluidity of 0.5 to 1000 Pa · S is obtained, it becomes soft enough to be sampled, and after hardening, a sufficient hardness is obtained, such as a fracture. It is possible to exert a sufficient function for fixing the.

In the thermoplastic resin 17a, wax is used for adjusting the fluidity of the thermoplastic resin 17a during molding, talc is used for adjusting the flowability, and polyester fiber is used for hardness and elasticity reinforcement in the cured state. Is formulated as.

The tubular fixing mount 19 of the present invention using the thermoplastic resin 17a and the base material 16 is prepared as follows. Cloth 16c of thermoplastic resin 17a, 1
To form a composite with 6d, first, a tubular core of the same shape is inserted into the inner cloth 16c so that the thermoplastic resin 17a does not adhere to the edge portions 19a and 19b at both ends, and the liquid thermoplastic resin 17a is formed. Dip inside. The outer cloth 16d is covered in a cured state after dipping, and the edges 19a and 19b at both ends of the two sheets are fixed to each other by a lock stitch so as to be one piece of cloth.

In this state, the outer cloth 16d can be heat-bonded to the outer side of the thermoplastic resin 17a laminated on the inner cloth 16c by exposing it to the high temperature tank at 120 ° C. for about 10 minutes. In the state taken out from the high temperature tank, before being cured, the thickness is molded to about 1 cm. As for the form of the product, when a fractured part such as an arm or a leg is to be attached, as shown in FIG. 3 (A), the product has a straight shape and a diameter of about 5
The length may be 12 cm and the length may be about 15 to 50 cm. Of course, it may be formed in a size range other than this,
The above dimensional range is just an example.

The tubular fixing attachment 19 may be used in the field as follows. For example, a tubular fixing attachment 19 having a size suitable for the fractured part is selected and placed in a high temperature tank or the like to fluidize the thermoplastic resin 17a to a moldable degree. Attach it to the fractured part in the fluidized state. At the time of mounting, for example, in the case of a fracture of the arm, the arm is passed through the tube of the fixing attachment 19 and the fixing attachment 19 is passed up to the fractured part of the arm. In this state, the fixing attachment 19 is lightly pressed against the fractured part and the surrounding arm part. By pressing, the fixing attachment 19 becomes in a state similar to that when the fracture part and its periphery are modeled, and is cured in that state.

In this way, the fixing fitting 19 in a state of being sampled according to the fractured part and its surroundings can be used as it is for fixing the fractured part as a substitute for the cast having the conventional structure.

Table 1 below shows the results of comparing the strength of the product of the present invention having the above-mentioned constitution with a plaster formed from a conventional plaster bandage.

[0064]

[Table 1]

Incidentally, polyester 100 was used for the test.
%, 100D twin yarns were woven by plain knitting with 176 circular knitting machine gauges as a base material, and the thermoplastic resin having the above-mentioned constitution was laminated only on one surface of the base material to obtain a sample. On the other hand, as a comparison, a gypsum wrapping bag that has been mainly used in the medical field for a long time was used, and a mold formed by taking a mold in the state of gypsum mud and then solidifying was used as a comparative sample. Both samples were formed into strip-shaped test pieces each having a width of about 25 mm.

The strength is shown by bending proportional load (N) and bending maximum load (N) as bending stress. The test method is
In accordance with the test standard of JIS K 7171 (ISO 198: 1993), an autograph (manufactured by Shimadzu Corporation, A
G-500B universal testing machine). Test speed: 5 mm / min, fulcrum distance: 80 mm, support base radius: 2 mm, test room temperature: 23 ± 2 ° C., humidity: 50 ±
It was conducted under the condition of 5%.

From Table 1, it can be seen that the mold formed using the casting material of the present invention (indicated as the product of the present invention in the table) has a plaster bandage (indicated as the conventional product in the table) at the bending proportional limit load. It is confirmed that it can withstand a larger load than the mold formed from (1). Similarly, it is understood that the product of the present invention has a larger maximum bending load than the conventional product. The result is that the product of the present invention is more sufficiently considered in consideration of the difference in the thickness of the test piece,
It can be seen that the plaster has a sufficient hardness as compared with the conventional plaster cast formed by the plaster bandage.

That is, it was confirmed that the product of the present invention is stronger than the conventional product, does not have the brittleness that tends to be a gypsum mold, and does not easily break under normal use conditions.

Conventionally, since such a bone fracture is fixed using a plaster bandage, the bone fracture cannot be fixed on site. For example,
At the site of a bone fracture accident, as a first aid, use an appropriate material as a splint on the fractured part, transport it to the hospital with the splint temporarily fixed with a bandage so that the fractured part is preserved, and fix it with a plaster bandage at the hospital. Was going on.

However, if the fixing mount 19 of the present invention having the above-mentioned structure is used, the thermoplastic resin 17a can be used on site.
As long as there is a means for heating to such a degree that it can be fluidized, reliable fixing can be performed from the beginning without performing temporary fixing using a splint or the like.

Since the fixing fitting 19 of the present invention is not so bulky and lightweight, it can be always provided in an ambulance, a health room such as a school, or even a home.

In the case of fixing with a plaster bandage having a conventional structure, when the plaster bandage is removed for re-examination of the affected area, the bandages are adhered to each other, so that they are cut with scissors. Mounting equipment for fixation 19 using casting material
If you use the
Can be easily removed by spreading the fixing attachment 19 after softening it by locally heating it with a heat dryer or the like.

In the case shown in FIGS. 4 (A) and 4 (B), a modified example of the tubular fixing attachment 19 is provided so that the attachment or removal can be performed more easily. In the case shown in FIG. 4 (A), the disconnection portion 21 in which only the inner thermoplastic resin and the inner base material are omitted is formed with the outer base material remaining in the length direction of the cylinder with a predetermined width. It is provided. Therefore, the fixing attachment 19 shown in FIG. 4 (A), which is formed in a substantially C-shaped cross section, allows the arm to pass through with the disconnection section 21 open, and then gently presses the disconnection section 21 to close it. And cure it. When detaching, the arm 21 may be pulled out in a state in which the disconnection portion 21 is lightly opened and the diameter is increased.

Alternatively, the disconnection portion 21 may be arranged in the cylinder length direction.
Fixing attachment 19 that is completely separated at a predetermined interval to form
It may be formed so that its cross section has a substantially C shape. At the time of mounting, the thermoplastic resin 17a may be fluidized in the above-described manner, and instead of passing the arm through the cylinder, the fractured part 21 may be opened and put on the fractured part.

Further, when detaching, the thermoplastic resin 17a used in the present invention has a certain elasticity even in a hardened state unlike gypsum. You can remove the attached item. If it cannot be opened sufficiently for removal, it can be easily removed by slightly heating the vicinity of the disconnection part with a heat dryer to soften or fluidize the thermoplastic resin 17a to some extent. Can be done.

Further, in the fixing cast using the gypsum bandage of the conventional structure, when the gypsum bandage was removed for treatment, it was necessary to wrap and fix the gypsum bandage again. If you are using a mounting attachment, remove it when you remove it.
Since it suffices to spread the parts, the fixed sample 19 remains as it is, except for the expanded part.

Therefore, in the case where the same fixing as before is carried out again after the medical examination, when the removed fixing attachment 19 is reattached, it can be attached in conformity with the molding portion, so that it fits. It can be easily reattached in the state. After reattaching, lightly press in with the part that was widened when removing it warmed appropriately and softened,
Since that part also follows the shape according to the mounting location, it can be easily fixed again.

In the case shown in FIG. 4B, in addition to the structure shown in FIG. 4A, a snap 22 is provided on the disconnecting portion 21. The snap 22 is provided with a male mold on one side of the disconnection portion 21 and a female mold on the other side in a row at predetermined intervals,
After mounting for fixing a fractured part or the like, the snap 22 is detached and opened when necessary for medical examination or the like, so that removal can be easily performed. Of course, the snap 22 may be mounted with the snap 22 removed.

Further, the tubular mounting portion is provided with a removable window portion 23 in advance, and only the window portion 23 is detached in a state where the tubular mounting portion is mounted for fixing when a medical examination is required. Then, it may be configured so that the affected part of the bone fracture can be exposed. In this way, it is not necessary to remove the fixed attachment 19 each time an examination or the like is performed, and it is possible to suppress the influence on the fractured part due to the removal. Such a structure is shown in FIG.

The window 23 may be constructed so that it can be attached and detached by the snap 22 provided around the window 23 as in the above-mentioned configuration. Of course, the window part is also made of the same material as the mounted product, and when mounted for fixing,
It is hardened in an appropriate mold according to the fractured part, and the window part 23 may be attached and detached in such a state.

In the above description, the fixing device 19 for fixing a fractured part or the like has been described, but it can also be used for fixing, maintaining or correcting an affected part other than the fractured part. For example,
Naturally, it can be applied to cervical spine collars and corsets for spine correction.

For example, for cervical diseases such as whiplash, it is used so as to surround the cervix and limit the movement of the cervical vertebra, and reduce the burden of the weight of the head on the cervical vertebra to improve the symptoms.

Needless to say, No. 1 can be used as a shoe worn by a normal person on a daily basis, and can also be used as an orthopedic shoe that has been conventionally used for medical purposes in which deformation is corrected and painless pressure is dispersed. In the case of a conventional orthopedic shoe, a special shoe mold is once formed by molding, measuring, etc., and a shoe is made in accordance with this shoe mold. It is used to take a shoe that has been formed into a roughly shoe shape, and then harden it when used, so that you can easily make a shoe that matches your foot shape. Of.

In the above description, shoes have been mentioned as an example, but in sandals, slippers, sandals, etc., a molding material in which the thermoplastic resin of the present invention is sandwiched between base materials is used for the soles,
If the individual's foot mold is sampled in a state where the thermoplastic resin of the molding material is fluidized and then cured and used, it is possible to form footwear such as sandals having a bottom surface adapted to the individual foot mold.

(Embodiment 4) In this embodiment, a case where the present invention is applied to a clothing article as a wearing article having a molding function will be described.

For example, it can be applied to socks. A casting material in which a thermoplastic resin is thinly sandwiched between fibers of a material that has good air permeability and does not damp may be formed on socks or stockings provided with a bag-shaped portion into which a foot portion can be inserted.

With the bag-shaped part of the sock heated, the feet are put in the bag-shaped part while the thermoplastic resin in the bag-shaped part is fluidized.
In that state, the bag-shaped portion is lightly pressed from the outside, so that the bag-shaped portion is sampled in a state matching the shape of the foot. By allowing to cool in this state, a sock can be created in which the bag-shaped portion fits perfectly in the shape of a foot.

By wearing such socks, it is possible to carry out a clean and fashionable wearing in which unnecessary wrinkles, slack, dragging, etc. do not occur at the time of wearing. In the above configuration, the case where the casting material is used only in the bag-shaped foot portion has been described, but it may be adopted in the leg portion.

Further, by using the casting material having the above-mentioned structure for clothing which is directly worn such as underwear to be worn, it can be effectively used as body-correction clothing. For example, if the thermoplastic resin is worn in a fluidized state, the body shape is adjusted in this wearing state, and then the body is cured and then used, it can be used as a body-correcting clothing item for each individual. . The body shape correction should be performed according to the body shape of each wearer, and conventionally, it has not been possible to easily create a corrective clothing item according to the body shape of an individual wearer. By using the product, it is possible to provide an inexpensive body shape-correcting clothing product that can be produced at a low cost.

The present invention is not limited to the description of the above embodiments, and is within the scope not departing from the gist of the present invention.
Various changes may be made.

For example, in the description of the above-mentioned embodiments, thermoplastic resin, synthetic rubber, or the like is used as the thermoplastic material, or if the material has the thermoplasticity as a function necessary for the constitution of the present invention, Materials that are not included in the categories of resin and synthetic rubber can also be used.

In the above embodiment, the inner socket,
Fixtures for fixation of bone fractures, cervical collar, corset,
Although the case of being configured as shoes, socks, stockings, etc. has been described, the wearing article of the present invention can be applied to various other things. An example thereof will be given below.

A product form as an orthopedic medical appliance is contemplated. Conventionally, as a brace in this field, it is mainly a product for treatment based on the patient's model or measurement,
The thermoplastic resin sheet itself was used as a manufacturing material in a bare state. However, most of such sheet materials are hard polyethylene or soft polyethylene, and the sheet material developed as a general industrial material is merely diverted.

Therefore, it cannot be said that the characteristics of the orthopedic medical device as a manufacturing material, the moldability, the influence on the treatment, and the physical application to the body are not sufficiently pursued.

However, the material used as the wearing article of the present invention is a molding material having a structure in which a thermoplastic material such as a thermoplastic resin is laminated on the base material. It is a structure that allows for precise mold taking by using it. Therefore, as compared with the above-mentioned conventional solid sheet material, it has extremely fine formability including precision molding.

Furthermore, since the thermoplastic resin is not used as it is as the exposed material for the molding material used in the present wearing article, it is used in a state of being laminated on a base material such as cloth.
When worn on the body, a soft contact feeling can be obtained on the skin. Also, since only thermoplastic resin does not have air permeability,
There is no escape area for sweat that comes out of the skin when it is in direct contact with the skin, but since it is in contact with the thermoplastic resin through the base material such as cloth, it is an escape area for sweat, etc. It is possible to secure the sex.

The wearing article of the present invention using the molding material having such characteristics exhibits extremely excellent effectiveness as an orthopedic medical device. For example, orthopedic shoes, ankle foot orthosis, knee orthosis, long leg orthosis, crotch orthosis, pelvic girdle long leg orthosis, leg expulsion orthosis (sciatic long leg orthosis, short leg orthosis, ankle support foot orthosis), trunk orthosis (Cervical hernia, degenerative cervical spondylosis, cervical spinal cord injury, cervical spine tumor, thoracic spine caries, thoracolumbar sacral fracture, spinal osteoporosis, acute low back pain, degenerative spondylosis, lumbar disc herniation, spondylolisthesis, thoracic kyphosis, lateral Adaptable orthoses for patients with kyphosis, etc., and orthoses such as the hands, wrists, elbows, and shoulders.

Furthermore, the present invention can be applied to cosmetic covers for lower and upper limbs related to orthopedics, and prosthetic moldings for resection of breast cancer.

Further, a usage form as a tool for sports or the like can be considered. For example, by using a cloth having a high cushioning property as a base material, it can be used for walking shoes, interiors of protectors used for the purpose of cushioning or fitting, and inner shoes such as skis and mountain climbing shoes.

By using a rubber-based resin and a soft cloth as the base material, the stretchability, barrier property, shape property, etc. can be utilized,
It can also be applied to suits, skin diving suits, and shape-up body suits with breathable fabric. By using a non-slip cloth made of a rubber-based resin, it may be possible to apply it to grips of various articles that make use of its shape.

Further, it can be considered to be applied to an exclusive case which is provided with fixing, buffering and ventilation. For example, in the case of paintings, works of art, old documents, archeological shaped items, excavated items, glasswork products, medals, cups, development samples, etc. In this case, the wearing article of the present invention is
Since a mold can be taken at the time of mounting, a preferable case can be manufactured.
