【考案の詳細な説明】
本考案は殺菌性整形用固定材料に関する。従来
よりギブス固定、副木、採型用ギブス、訓練用義
肢等の整形用固定材料として石膏包帯を用いるこ
とが知られている。これら石膏包帯は患部の固定
及び外部からの衝撃に対する保護としては十分に
有効であるが、非常に重くかつ、通気性がほとん
どなく、更に一度硬化すると湿気があるとき、例
えば水と接触した場合急速に強度を失い脆くなる
という欠点を有する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sterilizing orthopedic fixation material. BACKGROUND OF THE INVENTION It has been known to use a plaster bandage as a fixing material for fixing casts, splints, casts for casting, prosthetic limbs for training, and the like. Although these plaster bandages are quite effective in immobilizing the affected area and protecting against external impacts, they are very heavy, have little air permeability, and, once hardened, can be used quickly in damp conditions, such as when coming into contact with water. It has the disadvantage of losing strength and becoming brittle.
その上、ギブス装着のままではＸ線撮影が難し
く患部の治瘉状態を診断するためには石膏ギブス

いるものなどが開発されているが前者は軟化温度
が約80℃と高温であり、又柔軟性に欠けるため、
肢体等に十分にフイツトせずタツクがとりにくい
などの欠点を有している。 Furthermore, it is difficult to take X-rays with the cast still in place, and the plaster cast must be removed in order to diagnose the healing status of the affected area, which is extremely unreasonable for both the doctor and the patient. In recent years, fixing materials for orthopedics that replace plaster bandages have been developed, such as those using heat-softening polymer compositions and those using ultraviolet curable resin compositions, but the former has a high softening temperature of approximately 80°C. and lacks flexibility,
It has the disadvantage that it does not fit the limbs sufficiently, making it difficult to take a tack.
後者は紫外線硬化型樹脂組成物を使用するため
紫外線照射装置が必要となり、費用がかさみ、か
つ装置の取扱いが難しく、更には紫外線が紫外線
硬化型樹脂を用いた包帯の上層に到達するのみで
内部まで硬化するのに相当の時間を要するという
欠点を有している。 The latter requires an ultraviolet irradiation device because it uses an ultraviolet curable resin composition, which increases costs and makes the device difficult to handle.Furthermore, the ultraviolet rays only reach the upper layer of the bandage made of ultraviolet curable resin, causing damage to the internal parts. It has the disadvantage that it takes a considerable amount of time to harden.

た。 A bandage impregnated with an isocyanate prepolymer described in JP-A-53-61184 and other publications is available as a fixing material for orthopedics that has improved these drawbacks. When the affected area is fixed and fixed using a bandage impregnated with the above-mentioned isocyanate prepolymer, it weighs about half as much as a conventional plaster bandage, and has excellent water resistance, X-ray photographability, and breathability. It has become possible to achieve a strong fixation, allowing for continuous use over a long period of time. However, if used continuously over a long period of time, the fixing material will gradually become contaminated with bacteria, and the bacteria will pass through the porous pores and multiply on the surface of the affected area, producing a foul odor. It was also found that the condition was not favorable from the viewpoint of healing of the affected area.

Any prepolymer having an isocyanate group in the molecule obtained by reacting a functional isocyanate or a mixture thereof may be used, and the viscosity is at 25°C.

同時に非常に使い難いものとなる。 On the other hand, as the hydrophobic fiber fabric, a warp knitted fabric having a warp elongation of 10% or less and a weft elongation of 20 to 150% is preferably used. If the warp elongation is 10% or more, it lacks workability and shapeability, and if the weft elongation is less than 20%, the fitting properties are poor and interlayer adhesion during fixation is reduced, making it impossible to obtain sufficient strength. . Furthermore, if the weft elongation exceeds 150%, the workability is poor and the resin liquid adheres unevenly, making it extremely difficult to use.

る。 The fibers constituting the hydrophobic fiber fabric used in the present invention are preferably polyolefin synthetic fibers with a water absorption rate of 0.1% or less. The water absorption rate here refers to the official moisture content, and examples of fibers include polypropylene fibers and polyethylene fibers.

Since the resin composition used in this invention easily reacts with water, the moisture contained in the fibers reacts with the resin composition during the storage period until it is used as a fixing material for shaping, and the resin composition reacts with the resin composition before being used as a fixing material for shaping. Problems such as reaction progressing and curing are likely to occur.

とによる。 Further, the hydrophobic fiber fabric used in the present invention is preferably a warp knitted fabric. The size of the warp knitted fabric is not particularly limited, but from the viewpoint of ease of use, the width is 5 cm to 30 cm.
cm, preferably 10cm to 20cm, length 2m to 5m,
Preferably, one with a length of 3 m to 4 m is used. The reason why a warp knitted fabric is preferably used is that it is extremely easy to handle without causing problems such as selvage even when it is stretched during processing or use.

た再シール可能な袋でもよい。 Since the sterilizing fixing material for orthopedic surgery of the present invention easily reacts with water and hardens, it is necessary to store it in a moisture-free state. Therefore, the fixing material is stored in a sealed container that can prevent moisture from entering to the extent that the fixing material does not react to the extent that it becomes unusable during the storage period. The hermetically sealed container may be a film made of polyolefin, polyester, polyamide, etc., a film on which aluminum is vapor-deposited, a laminated film using these films on at least one side, or a bag made of resin-coated aluminum foil, in an amount equivalent to one dose. It may be a heat-sealable bag containing several doses, or it may be a resealable bag containing several doses.

とが好ましい。 From the viewpoint of ease of use, it is preferable that the fabric is stored wrapped around the outer circumference of a rod-shaped body made of a hydrophobic material, and the rod-shaped body may be solid or hollow. It may be tubular. Further, its cross-sectional shape may be circular or polygonal. In the case of a circular shape, it is preferable that the surface has small irregularities. Alternatively, it may be in a rolled or folded form without using such a rod-shaped body. As the hydrophobic rod, a polyolefin resin rod having a water absorption rate of 0.1% or less is preferably used, and examples thereof include rods made of polyethylene or polypropylene resin. The orthopedic fixation material stored in the sealed container is taken out from the container at the time of use, and is heated with water or hot water, preferably 20-35℃.
It is preferable that the immersion time does not exceed 1 minute.

重量でよく非常に軽量である。 After dipping, it is squeezed out and used to cover affected areas such as limbs, depending on the purpose. In this case, it is also possible to add an alkaline substance, such as an isocyanate activator such as a tertiary amine, to the water or hot water in order to accelerate the reaction between the -NCO group and the water. The air-permeable molded article containing the water-insoluble sterilizing metal or sterilizing metal compound thus formed passes through the porous pores from the outside of the molded article and penetrates into the inside of the molded article. Bacteria are sterilized and the surface of the affected area can always be kept sterile, making it extremely hygienic. In addition, in order for orthopedic products such as casts and prosthetic limbs formed in this way to exhibit the same support and fixation effect as orthopedic products obtained from plaster bandages, they only need about half the weight of plaster bandages, which are extremely lightweight.
