Point to one.

  Here, first, the photocurable medical fixing material 1A according to the first embodiment of the present invention will be described with reference to FIGS. FIG. 2 is a schematic view of the photocurable medical fixing material 1A according to the present embodiment. FIG. 3A is a perspective view showing a configuration of the photosensitive part 10 of the photocurable medical fixing material 1A according to the present embodiment. FIG. 3B is a perspective view showing a configuration of the non-photosensitive portion 15 of the photocurable medical fixing material 1A according to the present embodiment (in FIGS. 3A and 3B, each configuration is shown). For the sake of explanation, only a part of FIG. 2 (a part where a photosensitive part 10A described later is located) is shown, and the photosensitive part 10A is exposed from the cover members 300A and 300B. ). FIG. 4 is an explanatory diagram for explaining a procedure for mounting the photocurable medical fixing material 1 </ b> A according to the present embodiment on the lower limb X. Hereinafter, in each drawing referred to in each embodiment, those having substantially the same functional configuration are denoted by the same reference numerals, and redundant description is omitted.

  The photocurable medical fixing material 1A is attached to the lower limb X or the like as a splint material, and is used for fixing or supporting an affected part or the like. A photocurable medical fixing material 1A shown in FIG. 2 includes a photocurable resin, and includes a light-sensitive part that is cured after light irradiation and a non-light-sensitive part that is not cured after light irradiation. That is, the photocurable medical fixing material 1A mainly includes the light-sensitive part 10 that is cured after light irradiation and the non-light-sensitive part 15 that is not cured after light irradiation.

  First, as a premise for detailed description of the configuration of the photocurable medical fixing material 1A, the light-sensitive part 10 and the non-light-sensitive part 15 will be described (see FIGS. 3A and 3B). As illustrated in FIG. 3A, the light receiving unit 10 includes a photocurable resin 100 and a base material 200. In addition, the photosensitive part 10 includes a cover material 300A that covers the affected part side of the photosensitive part 10 and a cover material 300B that covers the photosensitive part 10 from the side facing the affected part side when mounted on the human body. Have. Further, a cushioning material 400 is provided on the affected part side of the cover material 300A. The photosensitive part 10 is cured by irradiating light. The light source for curing the photosensitive part 10 may be a light source that emits light having an absorption wavelength of a photopolymerization initiator described later (for example, a light source that emits visible light or a wavelength of 400 nm or less).

  As shown in FIG. 3B, the non-photosensitive portion 15 includes a photocurable resin 100 and a light shielding member 150 that covers the photocurable resin 100 and shields it from light. More specifically, the non-photosensitive portion 15 includes the photocurable resin 100 (also used in the above-described photosensitive portion 10), the base material 200, the cover material 300A, the cover material 300B, and the buffer material 400. And a light shielding member 150 that shields the light curable resin 100 from light. That is, the non-photosensitive portion 15 is obtained by shielding the photocurable resin 100 with the light shielding member 150 and is different from the light sensitive portion 10 in that it is covered with the light shielding member 150.

  Since the photocurable resin 100 included in the non-photosensitive portion 15 is shielded from light by the light shielding member 150, the photocurable resin 100 does not cure even after light irradiation and has a lower hardness than the photocurable resin 100 included in the photosensitive portion 10. Have. That is, the non-light-sensitive part 15 is different from the light-sensitive part 10 and can be deformed even after light irradiation. Therefore, since the non-light-sensitive part 15 maintains the non-cured state after the light irradiation and the light-sensitive part 10 is cured after the light irradiation, the non-light-sensitive part 15 is shown in FIG. It is possible to prevent the photocurable medical fixing material 1A from fixing the fruit portion X1 and the sole M3.

  In addition, although the photocurable resin contained in the photosensitive part 10 and the photocurable resin contained in the non-photosensitive part 15 are described with the same reference numeral 100, The photosensitive part 15 does not necessarily include the same photocurable resin.

  3A and 3B show an example in which the photocurable resin 100 is laminated on the base material 200 for the sake of explanation, but this embodiment is limited to this example. Not. For example, the photocurable resin 100 may be held by the base material 200. Here, “holding” includes, for example, impregnation, lamination, sticking, and application.

  The base material 200 according to the present embodiment has a structure in which six layers are stacked. The laminated structure may be, for example, a thinner laminated structure of 5 layers or less, or conversely, a thicker 7 layer or thicker laminated structure.

  Next, after describing the configuration of the photocurable medical fixing material 1A, the photocurable resin 100, the light shielding member 150, the base member 200, the cover materials 300A and 300B, which form the photocurable medical fixing material 1A, The cushioning material 400 will be described in more detail.

  As shown in FIG. 2, the light receiving unit 10 includes two parts, a light receiving unit 10A and a light receiving unit 10B. Further, the non-light-sensitive part 15 includes three parts, that is, a non-light-sensitive part 15A, a non-light-sensitive part 15B, and a non-light-sensitive part 15C. The non-photosensitive part 15A is provided so as to be connected to the photosensitive parts 10A and 10B.

  As shown in FIG. 4 to be described later, the light receiving unit 10A and the light receiving unit 10B cover the position between the fruit part X1 and the sole M3 in the lower limbs X. And the non-light-sensitive receiving part 15 coat | covers the convex part and / or movable part in a to-be-mounted body. 1 A of photocurable medical fixing materials are mounted | worn with a leg, and the non-light-sensitive part 15 is located in the convex part and / or movable part of the fruit part X1. More specifically, the non-light-sensitive part 15A covers the sole M3, and the non-light-sensitive parts 15B and 15C cover the fruit part X1.

  In view of the fact that the photocurable medical fixing material 1A covers the lower limb X of the human body, the dimensions of the photocurable medical fixing material 1A can be appropriately adjusted according to the size of the human body.

  The photocurable resin 100 included in the light-sensitive part 10 and the non-light-sensitive part 15 is a resin that is cured by light irradiation. The photocurable resin 100 contains other components such as a photosensitive resin and a photopolymerization initiator.

  As photosensitive resin, there exists resin which has the photosensitive group which can be bridge | crosslinked by light irradiation, for example. Specific examples include acrylic photocurable resins having acrylic acid esters, methacrylic acid esters, and the like, photoradical addition-type and photocationic polymerization-type resins, and the like. Moreover, as a photoinitiator, what is necessary is just the substance which produces | generates a radical or a cation by light irradiation. Moreover, you may contain components, such as a photosensitizer, as needed.

  Although it does not specifically limit as the photocurable resin 100, For example, the urethane type (meth) acrylic acid derivative obtained by the polyisocyanate which has two isocyanate groups, and the (meth) acrylic acid derivative which has an active hydrogen group A photocurable resin containing an oligomer and a titanocene photopolymerization initiator that absorbs light of 400 to 700 nm can be used (for details, refer to WO2006 / 090605).

  Various components can be further blended into the photocurable resin 100 as necessary. For example, a stabilizer (additive for preventing gelation during storage and maintaining storage stability) can be blended. Examples include polymerization inhibitors, antioxidants, tack-free agents, thixotropic agents, silane coupling agents, surfactants, photosensitizers, and organic or inorganic fine particles.

  In order to harden the photosensitive part 15 by light irradiation after the photocurable medical fixing material 1A is attached to the human body, and to fix the affected part etc. sufficiently, the photocurable type fixing material 1A is photocurable. The three-point bending strength of the resin 100 is preferably 20 to 120 N / cm, and more preferably 30 to 120 N / cm. In addition, as a photocurable medical fixing material according to the second embodiment, a photocurable resin contained in a cast material described later also has an equivalent three-point bending strength.

  In the non-light-sensitive part 15, the light blocking member 150 is a member that blocks the light curable resin 100. The light shielding member 150 may be anything as long as it shields the photocurable resin 100 after being mounted on the human body H. For example, the light shielding member 150 is coated with a metal thin film, a metal fixing film, an opaque colored film, a pigment / dye, or the like. It can be a thin film such as a film. The light shielding member 150 may be attached to the photocurable medical fixing material 1A before being attached to the human body H, or may be attached to the photocurable medical fixing material 1A when being attached to the human body H. Good.

  Regarding the thickness of the light shielding member 150, after the photocurable medical fixing material 1 </ b> A is attached to the human body H, the light shielding member 150 does not interfere with the movement of the human body, and the photocurable resin 100 can be shielded from light. From the viewpoint, it is preferably about 0.01 to 5 mm. More preferably, the thickness is about 0.01 to 1 mm.

  The substrate 200 is a member that holds the photocurable resin 100 in order to form the photocurable medical fixing material 1A. As the base material 200, woven fabrics, knitted fabrics, nonwoven fabrics and the like using various fibers can be used. As the fiber, natural fiber and chemical fiber can be used, and examples thereof include cotton, hair, rayon, polyamide fiber, polyester fiber, acrylic fiber, polyolefin fiber, glass fiber, carbon fiber, and other fibers. About the thickness of the base material 200, it is preferable that it is about 3-25 mm, More preferably, it is about 5-15 mm.

  The cover members 300A and 300B transmit light and cover the side surface in the horizontal direction with respect to the affected part of the photocurable resin 100, and the photocurable resin 100 before curing flows, so that the photocurable medical material is used. This is a resin stopper for preventing leakage from the inside of the fixing member 1A (see FIGS. 3A and 3B). The cover materials 300A and 300B are preferably non-reactive with the photocurable resin 100 without penetrating the photocurable resin 100 and coming out of the surface.

  A film that transmits light can also be used as the cover members 300A and 300B. As the material, polyester, for example, polyolefin such as polypropylene (PP) and polyethylene (PE), polyvinyl chloride, nylon, polyurethane and the like can be used. The cover material may be used in combination with the above-described knitted fabric, woven fabric, non-woven fabric, sheet or the like. A plurality of cover materials may be provided in a direction perpendicular to the affected area.

  The cushioning material 400 has a cushioning property due to contact of the photocurable medical fixing material 1A with the human body. Further, the cushioning material 400 has appropriate air permeability, the reaction heat of the photocurable resin 100 at the time of curing is not easily transmitted to the side of the affected part, etc., is easily deformed following the shape of the affected part, and has moldability. Good things are good. As the buffer material 400, for example, polyester-based fibers, nonwoven fabrics, foams, neoprene rubber, or the like can be used. The buffer material 400 may be a multilayer or may be provided on the side opposite to the affected part.

  Next, the effect of the photocurable medical fixing material 1A according to the present embodiment will be described. With reference to FIG. 4, the operation and effect of the photocurable medical fixing material 1 </ b> A will be described in detail while explaining the procedure for mounting the above-described photocurable medical fixing material 1 </ b> A to the human body H.

  As shown in FIG. 4, here, a case where the photocurable medical fixing material 1A according to the present embodiment is attached to the lower limb X will be described as an example (see FIG. 4A). The photocurable medical fixing material 1 taken out from a packaging material or the like that does not have light permeability is attached to the lower limb X (see FIG. 4B). As shown in FIG. 4B, the light receiving unit 10A and the light receiving unit 10B are mounted on the sole M3 and the fruit part (more specifically, the inner fruit and outer fruit) X1 of the lower limb X.

  Next, the light-shielding member 150 is attached to the position of the sole M3 of the photocurable medical fixing material 1A to form the non-light-sensitive part 15A (see FIG. 4C). Moreover, the light shielding member 150 is attached to the position of the fruit part X1 of the photocurable medical fixing material 1A, and the non-light-sensitive part 15B and the non-light-sensitive part 15C are formed.

  In addition, about attachment of the light shielding member 150, it is possible to employ | adopt arbitrary methods, such as winding and sticking of the light shielding member 150 to 1 A of photocurable medical fixing materials. In the above-described embodiment, the case where the light shielding member 150 is attached to the photocurable medical fixing material 1A after the photocurable medical fixing material 1A is mounted has been described as an example. In 1A, before attaching the photocurable medical fixing material 1A to the human body H, the light shielding member 150 may be attached to the photocurable medical fixing material 1A in advance.

  Next, the light 500 is irradiated to the photocurable medical fixing material 1A (see FIG. 4D). The light receiving unit 10A and the light receiving unit 10B are cured by the light irradiation. On the other hand, the non-light-sensitive parts 15A, 15B, and 15C maintain a non-cured state even after light irradiation. For this reason, in the photocurable medical fixing material 1A, it is possible to prevent the fruit portion X1 (convex portion) and the sole M3 (movable portion) from being fixed.

  Thus, according to the photocurable medical fixing material 1A, the non-light-sensitive part located at the fruit part X1 (convex part) and the sole M3 (movable part) while fixing the lower limbs X by the light-sensitive part 10. 15 can be prevented from curing.

  Therefore, in the photocurable medical fixing material 1A, the pressure applied to the fruit portion X1 (convex portion) and the sole M3 (movable portion) can be dispersed, and the person wearing the photocurable medical fixing material 1A It is possible to exercise such as walking in a state equivalent to the case where the photocurable medical fixing material 1A is not worn. In particular, with respect to the sole M3 serving as a movable portion, the lower limb X can be operated, and rehabilitation can be appropriately performed. That is, in the photo-curable medical fixing material 1A, the affected part or the like is fixed, and “recovery of fractures, sprains, etc.” is promoted, and other parts of the fixing material are brought into a non-hardened state, thereby performing rehabilitation and the like. It is possible to prevent “muscle atrophy or muscle contracture”. That is, in the photo-curable medical fixing material 1A, the contradictory relationship between “recovery of fractures and sprains” and “prevention of muscle atrophy and muscle contracture” can be solved.

  When moving in rehabilitation of an affected part or the like, it is possible to reduce pain due to the photocuring medical fixing material 1A coming into contact with the fruit part X1 which is a convex part. In addition, it is effective for a sprained patient to keep the sole M3 in a flexible state when the photocuring medical fixing material 1A is attached to the lower limb X.

<Production of photocurable medical fixing material>
As the base material, a tape-shaped base material in which glass fibers are Raschel knitted to a width of 100 mm with a basis weight of 270 g / m ² , a basis weight of 270 g / m ² , a weft of 11 / 2.54 cm, and a weft of 270 g / m ² was used.

  For the photo-curing resin, 99.9 parts by weight of AH-600 (manufactured by Kyoeisha Chemical Co., Ltd.), a phenylglycidyl ether (meth) acrylate hexamethylene diisocyanate urethane prepolymer, was placed in a beaker and heated to 60 ° C., and photopolymerization initiator Irgacure 784 (bis (cyclopentadienyl) -bis (2,6-difluoro-3- (pyrrol-1-yl) phenyl) titanium: manufactured by BASF) 0.05 parts by weight of N-methyl-2- A solution dissolved in 0.05 part by weight of pyrrolidone was added for adjustment.

The base material was impregnated with 260 g / m ² of a photocurable resin, and six layers thereof were laminated. Pressurized at 2 kPa for 1 minute to adhere the layers to form a core material.

The cushioning material is a non-woven fabric with a two-layer structure, one layer is a polyester non-woven fabric (inner side = core material side), and the other layer is made of a blended non-woven fabric of rayon and polyester (outer side = skin side). A two-layer nonwoven fabric of needle punch having a diameter of 3.2 mm and a basis weight of 300 g / m ² was used.
The core material was covered with a cover material (polyethylene / nylon laminate film) and placed on the cushioning material.

  That is, the photocurable medical fixing material has a structure in which a cushioning material, a cover material, a core material, and a cover material are laminated in this order from the body side.

<Light irradiation to photocurable medical fixing material>
In a measurement room adjusted to a room temperature of 23 ° C. and a humidity of 65% RH, a lighting unit / LED (manufactured by Alcare) was used as a light source. Illuminance was measured by dividing the 10 cm square area into 4 parts using LM-332 manufactured by ASONE Co., Ltd., and the center point was measured, and the distance between the light source and the sample was adjusted so that the average value of the 4 points was about 0 to 15000 lux. . The photocurable fixing material was cut into a 10 cm square, and the fixing material was irradiated for 1 minute for each illuminance.

<Evaluation method>
(3-point bending strength)
For the measurement, an autograph AG-D (manufactured by Shimadzu Corporation, computer measurement control type precision universal testing machine) was used, and a bending test was performed according to JIS K7171 using a three-point bending test jig. In the three-point bending test jig, the distance between the fulcrums was set to 50 mm. The test speed was 100 mm / min. The results are shown in Table 3 and FIG.
As for the non-photosensitive part, even if a light source equivalent to the above is used, the maximum three-point bending strength is 0.40 to 0.87 N / cm.
