Description

Description Attached products with a molding function

The present invention relates to a wearable device including a medical device, a rehabilitation device, and the like used for the purpose of reducing or recovering a dysfunction by externally supporting a human body part such as a limb or a trunk of a human body, This is a technology for mounting products that can be mounted according to the mounting site by providing a molding function to the device, and can eliminate poor mounting. Background art

In recent years, with the spread of rehabilitation medicine, various wearing products have been developed for the purpose of reducing and recovering functional disorders by supporting the skeletal musculature of the human body from outside the limbs and trunk. A fitting for such an application is particularly called a brace. Orthotics can be broadly categorized into fixed, supportive, straightening, unloading, walking, standing, and towing equipment, depending on the purpose of use.

Basically, it is desired that such an orthosis can be used in a state in which it is fitted to the wearing part of the human body and does not cause discomfort or pain when worn. For this purpose, the necessary measurements are taken to create the brace. However, measuring is a method of measuring dimensions from the outside with a single measure, and it is not possible to read the uneven shape of the human body in the mounting part more sufficiently than in measuring. For this reason, with an orthosis made based only on measuring, it is not possible to fit the delicate unevenness of the mounting part, and some parts will be rubbed at the time of mounting etc., and it is difficult to obtain a perfect wearing feeling, Wearing is often a pain for patients.

In addition, the perfect fit is not limited to the equipment used for medical purposes, etc., but also applies to everyday clothing such as underwear, clothes, socks, gloves, and hats. . Furthermore, footwear such as shoes may be used. The shape of the foot varies greatly depending on the individual, such as the height of the instep, as well as the size of the foot. Originally, shoes that match each individual footprint are desirable. However, at the moment, make do with ready-made shoes Is often the case. The problem of hallux valgus, which has become a problem in recent years, is also a physical obstacle caused by wearing shoes that do not fit the footprint or wearing narrow shoes.

In addition, proposals have been made to protect the products other than those used for the human body, by using a force par according to the shape of the product as a protective cover for the product. By moving away from the idea of simply covering the product and creating a force pattern that matches the product details, unnecessary movement of the product inside the cover is accurately prevented and its protection is ensured. It has been proposed to.

As mentioned above, many products, including clothing accessories, are ideally ideal to be able to be worn according to the type of wearer. In order to realize such an ideal mounting state, it is required to make products by molding rather than measuring only.

However, at present, technologies that can be easily and routinely cast without any special knowledge have not been developed so far. In most cases, ready-made clothing, footwear, and other accessories are used to make it in time. Casting is troublesome and costly, so ready-made products are often used in time.

This is often not a serious problem for healthy people because it does not fit easily into the body or is not comfortable to wear.However, in the case of equipment used by persons with disabilities, the degree of disability is It becomes a serious problem such as worsening of the treatment, delayed treatment effects such as recovery and correction, or unsuitability for long-term wearing due to unsatisfactory wearing feeling.

On the other hand, even if the casting is easy, even if the production cost of the fitting based on it is high, including the casting, the fitting cannot be used sufficiently. Production based on different types of molds is inherently incompatible with mass production methods, and does not provide cost-effective mass production.

Therefore, the present inventor thought that it would not be possible to develop a technology that can be mounted as it is in a molded state. If it can be easily molded, and if it can be attached as it is or with a little modification, it will be possible to go from molding in the conventional technology to product creation Can be shortened. We thought that it would be possible to easily and inexpensively provide a product that fits perfectly to the mounting part.

In the case of conventional molding, for example, in the case of forming a medical appliance, a molding technique mainly using gypsum or a plaster bandage has been mainly used. Gypsum bandage, while the gypsum is softened, without the need to press the soft tissue of the affected part more than necessary, with an appropriate wrapping force, it is required that the gypsum be wrapped neatly while it does not dry. Normally, the work must be completed in about 5 minutes, and considerable skill is required to perform good casting.

In the actual medical practice, qualified prosthetics and orthotics have to be engaged in the casting that requires a doctor's prescription, and it is not easy to do things without knowledge. For this reason, although casting is inevitable for prosthetic limbs such as prosthetic arms and prostheses, orthotics used for orthodontic treatment, etc. are often standardized without performing casting. In many cases, the user had to select a suitable sheath from the ready-made sheaths with the following dimensions. In essence, it is necessary to mold strong sheaths according to the user.

An object of the present invention is to make it possible to easily form a model according to an object to be mounted on a variety of mounted articles including a brace and the like without performing complicated molding as in the related art, and mount the apparatus in that state. It is in. Disclosure of the invention

The present invention is formed of a stretchable base material in which a thermoplastic material such as a thermoplastic resin is laminated, and the mounting target is molded in a flowing state of the thermoplastic material, and is cured and mounted in the molded state. It is a wearing product having a molding function, characterized in that it is made to be able to be made. The base is a cloth.

The wearing article is characterized by being a brace for supporting a human body part such as a limb or a trunk of a human body and reducing or recovering a functional disorder. The wearing article is characterized in that it is formed as an inner socket to be attached to a stump on the side of a human body when attaching a prosthesis or the like. The wearing article is a clothing article. The wearing article is footwear such as shoes. The thermoplastic resin is selected from the group consisting of The mold has a fluidity of 0.5 to 1000 Pa · S.

The term “wear” as used herein means not only a thing worn by a person, but also an object other than a person, such as an animal or a plant, or a non-living object. For example, when a person is to be worn, clothing, footwear, hats, etc. are assumed to be worn, and these include equipment used for medical purposes. For example, the use of non-living objects as protective objects may include the use of protective covers, exteriors, storage cases, and cushioning materials for transport of various products such as electrical products.

Further, the term “thermoplastic material” used in the present specification does not mean a “plasticizer” added to impart plasticity to a resin or the like, but means a material having thermoplasticity. For example, it refers to synthetic rubber or thermoplastic resin. BRIEF DESCRIPTION OF THE FIGURES

(Embodiment 1) In the first embodiment, a description will be given of a case in which a mounted product having a molding function according to the present invention is applied to an inner socket used for mounting a prosthesis. FIG. 1 is a cross-sectional view showing a prosthesis mounted. FIG. 2 (A) is a perspective view showing an inner socket as a mounted product having a molding function according to the present invention, and FIG. (C) is a perspective view showing an inner core used for making the inner socket shown in (A).

First, the state of wearing the prosthesis will be described. As shown in FIG. 1, the prosthesis is first worn by putting a bag in which the stump 10 is placed as the elastic sheath 11 on the stump 10 of the patient. After that, the inner socket 12 molded according to the unevenness of the stump 10 is attached. Wear a bag-shaped elastic sheath 13 (also called a soft insert cover) on the attached inner socket 12.

In this state, the prosthetic leg 14 is mounted by fitting the inner socket 12 on which the telescopic sheath 13 is put on into the outer socket 14 a of the prosthetic leg 14. As the prosthesis 14, a force that can use various configurations conventionally known can be used. In the case shown in FIG. 1, a ready-made cosmetic foam 14b formed of a foam material and the like, and this cosmetic Form 14b is composed of a lower leg 14c at the bottom and an outer socket 14a supported by a rod-shaped support portion 14d standing on the leg 14c.

Conventionally, the inner socket 12 is mainly made of silicone rubber, and has a poor slip. When the stump 10 is mounted, the stump 10 is caught by the inner socket 12, and it is difficult to smoothly mount the inner socket 12 directly to the stump 10. For this reason, the inner socket 12 was mounted while wearing the elastic sheath 11 of a stump bag such as a sock.

Similarly, when attaching the inner socket 12 to the outer socket 14a, the inner socket 14 made of silicone rubber has a large friction inside the outer socket 14a molded with Atari® polyester. As described above, the telescoping sheath 13 also called a soft insert cover was worn, and then attached to the outer socket 14a.

The inner socket 12 of the conventional configuration is a female socket It was formed by cutting and bonding a foam sheet material to a male mold raised from the mold, or by thinly diving silicone rubber into the male mold. Furthermore, even though the inner socket 12 is made of silicon rubber, it is formed thinly, so that it may be broken at the time of mounting.

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

In a state where the thermoplastic material 17 has been fluidized, the mold is pressed directly against the stump, or the cast material is pressed into a male mold based on the female mold taken from the stump 10. By applying it to the mold, it is cured in that state and used as it is. That is, it is not made by diving silicone rubber into a male mold or by joining foam sheets, but it can be made extremely easily.

As shown in FIG. 2 (A), the inner socket 15 of the present invention is provided with an opening 15a for insertion of the stump 10 at one end so that it can be attached to the stump 10 of the lower limb. It is formed in a substantially straight bag shape with the other end closed. The inner socket 15 of the present invention is, in actual product form, for example, a bag shape, and a shape of the assumed end portion 1 ° is classified into several types, and a standard product conforming to each type. May be configured. In addition, even with the same shape, several different sizes may be prepared according to the general wearer's mode such as gender differences, adults and children.

As shown in FIG. 2 (A), the inner socket 15 of the present invention has two elastic cloths 16 a and 16 b formed in the same bag shape as a base material 16. It is configured by sandwiching a thermoplastic resin 17 a as a thermoplastic material 17 in a sandwich shape. Such a configuration is shown in the cross-sectional view of FIG.

The two cloths 16a and 16b sandwiching the thermoplastic resin 17a may be formed, for example, in a straight sock shape by circular knitting. For example, it may be configured as a dense knitting pile knit that combines spandex as a base yarn and a filament yarn (melting point of 255 ° C or more) such as polyester or nylon.

Product of inner cloth 16 b in the form of a bag with thermoplastic resin 17 a sandwiched between It is preferable to use at least the loop surface of the loop knitting on the outer surface of the outer surface of the outer surface of the cloth 16a. The reason for using the loop surface in the above range is that the thermoplastic resin 17a needs to be heated and fluidized in order to be ready for molding, but the heat in the fluidized state is required. The purpose is to prevent the heat conduction of the plastic resin 17 a to a certain degree, so that the inner socket 15 does not become difficult to handle, thereby preventing heat conduction to some extent.

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

Synthetic rubbers include styrene-butadiene-styrene (SBS), styrene-isoprene-styrene (SIS), styrene-ethylene-butylene-styrene (SEBS), and styrene-ethylene-propylene-styrene (SEPS).

Further, a crosslinked thermoplastic resin may be used. For example, a cross-linked polystyrene resin, a polyolefin resin, a polyurethane resin, an acrylic resin, a polyester resin, a polyamide resin, or the like, or a silane cross-linked synthetic rubber can be considered. 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 using the above-mentioned thermoplastic resin and synthetic rubber, talc for adjusting viscosity and other compounding agents may be appropriately used in consideration of fluidity at the time of molding. For example, a thermoplastic resin having the following composition can be considered.

SEP S (Septon 2043: Kuraray) 250 parts by weight Tackifying resin (Escolets 5320: Tonex) 200 parts by weight Process oil (KP 100: Idemitsu Kosan) 275 parts by weight Wax (NP 505: Mitsui Chemicals) 100 parts by weight wax (paraffin 155 °: manufactured by Nippon Seisakusho) 75 parts by weight

APAO (UT 2535: manufactured by Ube Lexen) 100 parts by weight The thermoplastic resin of such composition has a melt viscosity of 350 OmPa · s / 180 ° C. The softening point (R & B method) was 135 ° C. At the time of use, it shows fluidity enough to mold even at about 80 ° C, 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 sought fluidity that is easy to mold using various thermoplastic resins, and it was confirmed that the range is preferably 0.5 to 1000 Pa's (Pascal's). Was. If the fluidity is less than 0.5 Pa · S, the thermoplastic resin laminated on the base material flows, making it difficult to mold. In addition, when the temperature exceeds lOO OP aS, the thermoplastic resin is in a softened state but has poor fluidity, and the thermoplastic resin does not spread along the slightly uneven surface during molding. It is difficult to cast. The precision molding that is intended by the present invention cannot be performed in the state of softness without fluidity.

. More preferably, it is 2 to 200 Pa · S.

In the above measurement, a Punolex field viscometer Thermozel system rotor No. 28 20 rZm was used.

The composite of the thermoplastic resin 17a and the cloths 16a and 16b as the base material 16 is performed as follows. That is, the flat core 18 shown in Fig. 2 (C) is inserted into the bag-shaped inner cloth 16b to adjust its shape, and then dipped in the liquefied thermoplastic resin. I do. Diving shall be performed to the lower side of the inner socket 15b of the inner socket 15 shown in FIG. 2 (A). After curing, cover the outer fabric and expose to high-temperature bath at 150-160 ° C for about 10 minutes. In this manner, the outer cloth 16a can be thermally bonded to the thermoplastic resin 17a laminated on the inner cloth 16b. After heat-welding, lock-stitch the welt 15b part of the two cloths 16a and 16b and fix them together to one cloth. The shape is, for example, 10 to 15 cm in width and 1 cm in thickness, and is formed so that it can be extended to a maximum of 50 to 6'0 cm in circumference at the time of on-site molding. As the product form, it is sufficient to prepare products of various lengths. Thus, the bag-shaped inner socket 15 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 which the inner socket 15 is to be mounted. The selected inner socket 15 is heated on site, for example, in a high-temperature bath until the thermoplastic resin 17a falls within the above-mentioned fluidity range. For example, when the thermoplastic resin 17a having the above composition is used, it is heated at 140 ° C. for about 15 minutes. With the thermoplastic resin 17a fluidized so that it can be molded, put it on the patient's stump 10 and gently press it to fit the irregularities of the stump 10 so that the inner socket 1 Collect at 5.

After about 5 minutes in the molded state, the thermoplastic resin 17a cools and cures while maintaining the molded state. The cured product can be used as it is as an 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 10 to mold is described, but naturally, the molding is performed when the artificial leg is created. It may be pressed against the male mold that has been set.

In the inner socket 15 of the present invention, as described above, while the thermoplastic resin 17a is in a fluidized state, the mold is formed along the stump 10 or the uneven portion such as a male mold. However, if correction was required during or after casting, the hardened repaired part was again blown locally with hot air using a heat dryer or the like to fluidize the relevant part. In this condition, the mold can be remolded against the corresponding male part or stump.

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

In the case where the correction portion extends to the whole, the molded inner socket may be put again in the high-temperature bath for a predetermined time to fluidize the thermoplastic resin 17a as a whole, and the molding may be performed again. In addition, by following the procedure of the re-correction, even if the inner socket 15 becomes unnecessary, the thermoplastic resin 17a is again brought into a flowing state, so that the inner socket 15 at the other end can be used. It can be reused as. Such reuse is also effective from the viewpoint of resource saving. The thermoplastic resin 17a described above has rubber elasticity similar to that of silicon rubber, but is tougher than silicone rubber and does not break. This is because the thermoplastic resin 17a has inherent strength but is covered with the base material 16 such as the cloth 16a.

Furthermore, in the inner socket 15 of the present invention, since the base material 16 such as the cloth 16a and 16b is exposed on the inner surface and the outer surface, a cut end is attached to the inner socket 15. Also, it can be mounted smoothly with little friction and without getting caught. Similarly, when the inner socket 15 is attached to the outer socket 14a after being attached, unlike the case where silicone rubber is used, unnecessary friction does not occur, and the attachment to the outer socket 14a is smooth. Can be done.

Therefore, when the inner socket 15 of the present invention is used, it is also possible to omit the mounting of the elastic sheaths 11 and 13 required for mounting the silicon socket inner socket 12 having the conventional configuration.

As the inner socket 12 of the conventional configuration, a type formed by joining foamed sheet materials as described above is also known, but the inner socket 15 of the present invention which can be directly molded from the cut end 10 is known. It is possible to perform more elaborate molding, and the feeling of mounting is extremely favorable.

The stump 10 is actually a very complicated and delicate unevenness such as bone unevenness and muscle swelling, and it must be an elaborate mold that can support the weight evenly in this state. For example, a non-uniform load will be applied to the stump 10 and it will be difficult to wear it for a long period of time. However, since the inner socket 15 of the present invention can be mounted by using a molding material capable of performing elaborate molding as it is, such a disadvantage does not easily occur.

In the above description, the inner socket used for the prosthesis has been described. However, it is needless to say that the present invention can be applied to the inner socket used when attaching a stump such as an arm to the prosthesis. Furthermore, the configuration of the above-described inner socket of the present invention can be applied to a mounted article having substantially the same function and function as the inner socket.

The inner sockets used in the above description are also called soft sockets and soft sockets. Sometimes referred to as soft inserters, soft inserts, and soft liners.

(Embodiment 2)

In the present embodiment, a fixed attachment for use in treatment of a fracture or the like will be described. FIG. 3 (A) is a perspective view showing a fixing attachment 19 formed in a cylindrical shape, which is an example of an attachment having a molding function of the present invention, and FIG. 3 (B) is a cross-sectional view showing the configuration thereof. It is.

As shown in FIG. 3 (A), in the fixing attachment 19 of the present invention, two elastic cloths 16 c and 16 d of the same shape formed in a cylindrical shape are used as the base material 16 and the cloth 16 c , 16d are laminated with a thermoplastic resin 17a. As shown in the cross-sectional view of FIG. 3B, a thermoplastic resin 17a is sandwiched between two cloths 16c and 16d. The two cloths 16c and 16d are formed in a circular knitted tubular shape. Polyester or nylon yarn is combined with the base yarn of spandex, and the inner fabric is knitted in a fine loop pile at the center of the product.

The two edges 19a and 19b of the two cloths 16c and 16d are knitted with only spandex yarn, and the thermoplastic cloth 17a laminated on the inner cloth 16c and the outer cloth 16 At the stage where d is put on, it is locked to one piece of fabric 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.

25 parts by weight of ethylene vinyl acetate copolymer resin

(Evaflex 220: manufactured by DuPont Mitsui Polychemicals)

Adhesive resin (Alcon P 100: Arakawa Chemical Industries, Ltd.) 15 parts by weight Wax (HNP-9: Nippon Seisakusho) 35 parts by weight Talc (average particle size: 1.75 μπι) 25 parts by weight Polyester fiber (thick (0.5D, length 3mm) 0.2 parts by weight Thermoplastic resin with a strong blend has a melt viscosity of 420 OmPas / 180 ° C (Brookfield viscometer Thermosel system rotor No.27 20 r / m) and the softening point (R & B method) was 81 ° C. When using, 0.5-1000 By heating until the fluidity of P a · S is obtained, it becomes soft enough to mold, and after hardening, it has enough hardness and sufficient function for fixing fractures etc. Can be demonstrated.

In the above thermoplastic resin 17a, the plastics are used for adjusting the fluidity of the thermoplastic resin 17a during molding, the talc is used for adjusting the flow, and the polyester fibers are used for hardness and elasticity in a cured state. It is formulated for reinforcement. The tubular fixing attachment 19 of the present invention using the thermoplastic resin 17a and the base material 16 is produced as follows. To combine the thermoplastic resin 17a with the cloth 16c, 16d, first insert the same cylindrical core into the inner cloth 16c, and then insert the edges 19a, 19b at both ends. In a state in which the thermoplastic resin 17a is not attached to the surface, diving is performed in the liquid thermoplastic resin 17a. Cover the outer cloth 16d in the cured state after the diving, and lock the edges 19a and 19b at both ends to one cloth by lock stitching.

In this state, by exposing it to a high-temperature bath at 120 ° C for about 10 minutes, the outer cloth 16 d is heated on the outer side of the thermoplastic resin 17 a laminated on the inner cloth 16 c. It can be done. After being removed from the high-temperature chamber, it is molded to a thickness of about lcm before curing. As shown in Fig. 3 (A), when the product to be worn is a broken part such as an arm or a leg, the product is straight and has a diameter of about 5 to 12 cm and a length of about 1 to 12 cm. It may be formed to 5 to 50 cm. Of course, it may be formed in a size range other than the above, and the above size range is shown only as an example.

Such a tubular fixing attachment 19 may be used in the field as follows. For example, a tubular fixing attachment 19 having a size corresponding to the fracture is selected, and is placed in a high-temperature bath or the like, and the thermoplastic resin 17a is fluidized to an extent that it can be molded. In a fluidized state, attach it to the fracture. At the time of mounting, for example, in the case of a broken arm, the arm is passed through the cylinder of the fixed attachment 19, and the fixed attachment 19 is passed to the fractured part of the arm. In this state, lightly press the attachment 19 on the fracture and the arm around the fracture. By pressing, the fixation fitting 19 becomes in the same state as when the fractured part and its surroundings are cast, and is cured in that state.

In this way, the fixation fitting is molded to fit the fracture and its surroundings 19 can be used as it is as a replacement for the cast of the conventional configuration for fixing the fractured portion.

Table 1 below shows the results of comparing the strength of the product of the present invention having the above configuration with the cast formed with the conventional plaster bandage. table 1

On the other hand, as a comparative sample, a mold formed by collecting a gypsum mud in the state of gypsum mud using a gypsum wrapper conventionally used in the medical field and then solidifying the same was used as a comparative sample. Both samples were formed into strips of about 25 mm width.

The strength was expressed as the bending stress by the bending proportional limit load (N) and the maximum bending load (N). The test method was performed using an autograph (Ag-500B universal testing machine, manufactured by Shimadzu Corporation) in accordance with the test standard of JISK 7171 (ISO 198: 1993). Test speed: 5 mmZin, distance between fulcrums: 80 mm, support radius: 2 mm, test room temperature: 23 ± 2 ° C, humidity: 50 ± 5%. From Table 1, it can be seen that the mold formed using the molding material of the present invention (designated as the product in the table) is formed from the gypsum bandage (designated as the conventional product in the table) at the bending proportional limit load. It can be confirmed that the mold can withstand a larger load than that of the mold. Similarly, it can be seen that the product of the present invention is also larger in bending maximum load than the conventional product. The result is It can be seen that the product of the present invention is sufficiently harder than the casting plaster formed by the conventional gypsum dressing even when the thickness of the test piece is taken into consideration.

That is, it was confirmed that the product of the present invention is stronger in strength than the conventional product, does not have the brittleness that is often the gypsum type, and is not easily damaged under normal use conditions.

Conventionally, such fractures have been fixed using gypsum dressings, so that fractures could not be fixed on site. For example, at the site of a fracture accident, as an emergency measure, use appropriate materials as a splint for the fractured part, transport the splint to a hospital with the splint temporarily fixed with a bandage so that the fractured part is preserved, and plaster bandage at the hospital Had been fixed.

However, if the fixing attachment 19 having the above-described structure for fixing according to the present invention is used, a splint or the like may be used as long as there is a means for heating the thermoplastic resin 17a to the extent that the thermoplastic resin 17a is fluidized on site. Secure fixation can be performed from the beginning without temporary fixing. Since the fixing attachment 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 at home.

In addition, in the fixation with the plaster bandage of the conventional configuration, when removing the gypsum bandage to re-examine the affected area, the bandages are adhered to each other, so that they were cut with scissors or the like. If you use the fixed attachment 19, you can remove it by locally heating it with a heat dryer, etc., and then expand the attachment 19 when removing. Can be easily removed. The cases shown in FIGS. 4 (A) and 4 (B) are modified examples of the tubular fixing attachment 19, which can be easily attached or detached. In the case shown in Fig. 4 (A), the disconnection part 2 is omitted in the longitudinal direction of the cylinder with a predetermined width, leaving only the inner thermoplastic resin and the inner substrate, leaving the outer substrate. 1 is provided. Therefore, the fixing attachment 19 formed in a substantially C-shaped cross section as shown in FIG. 4 (A) should be passed through the arm with the disconnected portion 21 open, and then closed the disconnected portion 21. It is only necessary to lightly press and harden. When removing, the disconnection part 21 should be opened lightly and the arm should be pulled out with the diameter increased.

Alternatively, the disconnection portion 21 may be completely cut off at predetermined intervals in the length direction of the cylinder, and may be formed so that the cross section of the fixing attachment 19 is substantially C-shaped. . At the time of mounting, instead of passing the arm through the cylinder with the thermoplastic resin 17a fluidized as described above, it is possible to mount it over the fractured part with the open section 21 open. it can.

Also, upon removal, the thermoplastic resin 17a used in the present invention has a certain degree of elasticity even in a hardened state unlike gypsum. The attachment can be removed. If it is not possible to open it sufficiently enough to remove it, heat the thermoplastic resin 17a at least slightly with a heat drier to soften or fluidize the thermoplastic resin 17a. It can be easily removed.

Further, in the case of the casting plaster using the plaster bandage having the conventional configuration, when the plaster bandage was removed for treatment, it was necessary to re-wrap and fix the plaster bandage. When using the product, it is only necessary to spread the fixing device 19 so that it can be removed when removing it. It will be.

Therefore, when the same fixation as before is performed again after the medical treatment, when the detached fixation fitting 19 is reattached, it can be fitted according to the casting part, so that it is fitted Can be easily mounted again. After re-attachment, the part that has been spread out when removing it is appropriately heated and softened, and if it is gently pressed down, the part will follow the shape according to the part to be attached, so that it can be easily fixed again. In the case shown in FIG. 4 (B), in addition to the structure shown in FIG. 4 (A), a snap 22 is provided on the disconnection portion 21. The snap 22 is provided with a male force on one side of the disconnection part 21 and a female type on the other side at a predetermined interval in a row. After mounting for fixing a fractured part, etc., By removing the snap 22 and opening it, it can be easily removed. Of course, the snap 22 may be detached and attached.

In addition, a detachable window 23 is provided in advance on the cylindrical mounting part, and only the window 23 is detached when necessary for consultation, etc., while it is mounted for fixing. Then, it may be configured so that the affected part of the fracture can be exposed. In this way, it is necessary to remove the fixing attachment 19 every time a medical examination is performed. Therefore, the influence on the fractured part due to the removal can be suppressed. Such a configuration is shown in FIG.

The configuration of the window portion 23 may be, for example, detachable by a snap 22 provided around the window portion 23 as in the above configuration. Of course, the window is also made of the same material as the attached product, and when it is mounted for fixation, it is hardened in an appropriate molding state in accordance with the fractured part. It is only necessary to attach and detach 3.

In the above description, the attachment 19 for fixing a fractured part or the like has been described. However, it can be used for fixing, maintaining, or correcting an affected part other than the fractured part. For example, it is naturally applicable to a cervical spine collar, a corset for spine correction, and the like.

For example, for cervical disorders such as whiplash, the cervical spine is used to surround the neck and limit the movement of the cervical vertebrae, and to reduce the burden of the head weight on the cervical vertebrae to improve symptoms. Can be applied to color. Conventionally, a pre-made cervical vertebra collar is selected and used as much as possible for the patient's neck. However, it is ideal to use the cervical spine force adjuster tailored to the neck of the individual patient.

As shown in Fig. 5 (A), the mold is cut in the vertical direction so that it can surround the neck in advance, as shown in Fig. 5 (A), with the molding material having the thermoplastic resin sandwiched between the inner cloth and the outer cloth. The cervical spine collar 24 is formed in a short cylindrical shape provided with a portion.

The upper end of the cervical vertebra 24 is provided with an upwardly bent portion 25a so that the lower jaw of the upper cervical vertebra can be supported, and the lower end is appropriately inclined along the upper thoracic side of the cervical vertebra. A lower folded portion 25b of the edge is provided. The inner fabric 24a sandwiching the thermoplastic resin is a fabric that has a good touch to the neck when worn, and a part of the fabric is used as the upper folded portion 25a and the lower folded portion 25b. Is out.

The outer cloth 24 b should be made with a certain degree of design consideration so that it is possible to go out with the cervical vertebra collar 24 attached, and straddle the break 26. A hook-and-loop fastener 27 is provided so that the disconnecting portion 26 can be freely opened and closed, and can be easily attached and detached.

In use, select a cervical vertebra collar 24 that is approximately the size of the patient's neck and heat the selected cervical collar 24 to fluidize the thermoplastic resin. Fluidized In this state, open the disconnection part 26 and attach the cervical vertebra collar 24 to the neck of the affected part. After installation, lightly press the cervical vertebrae 24 on the neck, and gently press the upper folded part 25a and lower folded part 25b along the irregular shape of the lower jaw and upper chest. And mold it. If it is allowed to cool and cure in the cast state, it can be mounted as it is as a cervical vertebra collar 24 that fits into the patient's cervical vertebra by casting.

The lower jaw, upper chest, and neck area are used in a molded state, eliminating discomfort when wearing such as unnecessary rubbing, and causing ulcers and other disorders due to rubbing of the skin Can be used without. The attachment and detachment of the cervical vertebra collar 24 may be performed by removing the hook-and-loop fastener 27 of the disconnection portion 26 and opening the disconnection portion 26 using the elasticity of the thermoplastic resin.

In this state, lightly press the shoe 31 from the outside to fit the foot. In this state, it is allowed to cool for a while and then hardened in the mold state. The hardened state can be used as it is as the shoe 31.The shoe 31 has a rubber 16h on its outer side, as shown in Fig. 6 (B). It is only necessary to give a simple design. As the outer base material 16, besides the rubber 16 h, a cloth subjected to a water-repellent treatment can be used as long as it has elasticity.

Needless to say, the shoe 31 having the above-described structure having the casting function of the present invention can be used as a shoe worn by a normal healthy person on a daily basis, and is used for medical treatment in which deformation is corrected and painless pressure is dispersed. It can also be used as orthopedic shoes that have been used conventionally. In the case of conventional orthopedic shoes, once a special shoe last is formed by molding, measuring, etc. The shoe was made according to this last, but in the shoe of the present invention, the shoe was formed in a state where the shoe was previously formed into a roughly shoe shape with a casting material, and the shoe was cast. It is used as a shoe after being cured with, and it is very easy to make a shoe with a configuration that matches your footprint.

In the above description, shoes have been described, but in sandals, slippers, sandals, and the like, a molding material in which the thermoplastic resin of the present invention is interposed between base materials is used for a sole, and heat of the molding material is used. If an individual's last is cast in a state where the plastic resin is fluidized, and then cured and used, footwear such as sandals having a bottom surface matching the last of the individual can be formed.

(Embodiment 4)

In the present embodiment, a case will be described in which the present invention is applied to clothing as a wearing article having a casting function.

For example, it can be applied to socks. The molding material in which the thermoplastic resin is thinly sandwiched between the fibers of the material having good air permeability and no stuffiness may be formed into a sock or a stocking provided with a bag-like portion into which a foot portion can be inserted.

Heat the sock's bag-shaped part, put the foot into the bag-shaped part with the thermoplastic resin in the bag-shaped part fluidized, and then lightly press the bag-shaped part from the outside in this state to obtain the shape of the foot. In this state, the bag-shaped portion is molded. By allowing to cool in this state, a sock in which the bag-like portion is perfectly fitted to the footprint can be created. By wearing such a sock, it is possible to wear the product in a fashionable fashion without unnecessary wrinkles, loosening, and pulling. In the above configuration, the case where the molding material is used only for the bag-shaped foot portion has been described, but the molding material may be used for the leg portion.

In addition, by using the molding material having the above-mentioned structure in clothing worn directly, such as underwear worn on the body, the clothing can be effectively used as shape-correcting clothing. For example, if the thermoplastic resin is worn in a fluidized state, the body shape is adjusted in this mounted state, the mold is molded, and then cured, it can be used as clothing for body shape correction tailored to individuals. it can. Body shape correction should be performed according to the individual wearer's body shape, and in the past, it was not possible to easily create corrective clothing that matches the individual's body shape, but it had the casting function of the present invention. Inexpensive molding is possible and low by using It can provide inexpensive body-correcting clothing.

The present invention is not limited to the description of the above embodiment, and various changes may be made without departing from the spirit of the present invention.

For example, in the description of the above embodiment, a thermoplastic resin, a synthetic rubber, or the like is used as the thermoplastic material. If the material has thermoplasticity as a function necessary for the configuration of the present invention, a thermoplastic resin, Materials that do not fall under the category of rubber can also be used.

In the above-described embodiment, the case has been described in which an inner socket, an attachment for fixing a fracture or the like, a cervical spine, a corset, shoes, socks, stockings, and the like are configured. Can be applied to things. The following is an example.

A product form as an orthosis medical orthosis is conceivable. Conventionally, orthoses in this field have been mainly used for the treatment of patients based on their measurements or measurements, and the thermoplastic resin sheet itself has been used in a bare state as a material for the production. However, most of such sheet materials are hard polyethylene or soft polyethylene, and sheet materials developed as general industrial materials are simply diverted. Some properties have not yet been fully pursued to the extent that they are suitable for the properties of their materials, their formability, their effect on treatment, and their application to the body.

However, the material used as the mounting 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 a base material. In molding, the thermoplastic material is used in a fluid state. It is a configuration that takes into account that precision molding is possible. Therefore, compared to the above-mentioned conventional solid sheet material, it has extremely fine formability including precision molding.

In addition, the molding material used in this wearing product is not used directly as the thermoplastic resin, but is used in a state of being laminated on a base material such as cloth, so it is soft on the skin when worn on the body. A good contact feeling can be obtained. In addition, since thermoplastic resin alone does not have air permeability, there is no place for sweat that escapes from the skin if it is in direct contact with the skin Since it is in contact with the thermoplastic resin through a base material such as cloth, it is possible to secure an escape area for sweat and the like, and furthermore, to provide ventilation through the cloth.

The wearing article of the present invention using a casting material having such characteristics exhibits extremely excellent effectiveness as an orthosis medical orthosis. For example, orthopedic shoes, short leg brace, knee brace, long leg brace, crotch brace, pelvic band long leg brace, lower limb unloading brace (sciatic long leg brace, short leg brace, ankle supporting foot brace), trunk Orthotics (cervical hernia, cervical spondylopathy, cervical spinal cord injury, cervical spine tumor, thoracic vertebral caries, thoracolumbar sacral compression fracture, vertebral osteoporosis, acute lumbago, osteoporosis, lumbar disc herniation, spondylolisthesis, thoracic kyphosis) , Orthotics for scoliosis, etc., hand, wrist, elbow, shoulder and other orthotics.

Furthermore, it can be applied to cosmetic covers for lower limbs and upper limbs related to orthopedic surgery, and prosthetic molded products for breast cancer resection.

It can also be used as a tool for sports. For example, by using a cloth with a high cushioning property as the base material, it can be used for walking shoes, cushions or the interior of protectors used to achieve a fit fit, and inner shoes such as skis or mountain climbing shoes. Can also.

By using rubber-based resin and soft cloth as the base material, it takes advantage of stretchability, barrier properties, shape, etc. to make suits, skin diving suits, and body suits for shape-ups that allow the fabric to breathe. It is also conceivable to apply to such as. By using rubber-based resin and non-slip cloth, it can be applied to grips of various articles that make use of the shape.

In addition, it can be applied to exclusive cases that have only fixation, cushioning, and ventilation. For example, paintings, works of art, ancient documents, archeological artifacts, excavated items, glasswork, medals, cups, development samples, etc., may require a case that suits the circumstances. However, in such a case, the mounted article of the present invention can perform molding at the time of mounting, so that a preferable case can be manufactured. Industrial applicability

In the present invention, since the mounted product is provided with the molding function, it can be mounted in a state where it is molded according to the mounting target. In the present invention, since a mounting function is provided in advance to the mounted product, provision of a mounted product that can obtain a perfect mounting state is provided unlike the case where the mounted product is created from the mold once by molding. Can be performed very easily.

Since the molding function provided in the mounted product of the present invention is based on a thermoplastic material such as a thermoplastic resin, the molding can be easily corrected.
