〔産業上の利用分野〕
本発明は、放射線滅菌用包装材料および放射線滅菌され
てなる医療用具包装体に関する。さらに詳しくは、放射
線滅菌によって医療用具から発生する臭気を減少させる
ことのできる包装材料および包装体に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a packaging material for radiation sterilization and a radiation sterilized medical device package. More specifically, the present invention relates to packaging materials and packaging bodies that can reduce odors generated from medical devices through radiation sterilization.
医療用具の滅菌方法の１つとして、従来より放射線によ

した医療用具へのエチレンオキサイドの残留が問題とな
るにつれて、放射線滅菌の重要性が増大し、種々のディ
スポーザブル製品への適用が検討されている。A radiation sterilization method has been known as one of the methods for sterilizing medical tools. In particular, in recent years, as residual ethylene oxide in gas-sterilized medical instruments has become a problem, the importance of radiation sterilization has increased, and its application to various disposable products is being considered.

−１０４９７４号公報には脱酸素剤を含有する包装材料
を使用する方法が開示されている。Incidentally, when medical tools are sterilized by radiation, it has been a problem that odor is generated. This odor is thought to be generated by the decomposition of the polymer materials or their additives that make up the medical device, and is accompanied by considerable discomfort when the packaging is opened.Therefore, efforts were made to reduce this odor. Conventionally, some products have been packaged with a packaging material made of a breathable material such as paper to diffuse odors to the outside. Another method has been proposed in Japanese Patent Application Laid-Open No. 176659/1983, in which a gas adsorbent is sealed together with a medical device in a package to adsorb odors. As yet another method, JP-A-60-182952 discloses a packaging method using a polyethylene film to which magnesium hydroxide or calcium hydroxide is added;
Japanese Patent Publication No. 104974 discloses a method using a packaging material containing an oxygen absorber.
通気性材料を使用する方法では、十分な脱臭効果が得ら
れず、滅菌後かなりの時間が経過しても臭いが低減しな
いだけでなく、包装材料のコスト上昇を伴うので、経済
的にも好ましくなかった。The method of using breathable materials does not provide a sufficient deodorizing effect, and not only does the odor not reduce even after a considerable period of time has passed after sterilization, but it also increases the cost of packaging materials, so it is economically preferable. There wasn't.
また、ガス吸着剤を包装体内に封入する方法では、ガス
吸着剤の封入工程が必要になるために包装工程が複雑に
なるとともに、医療用具以外のものが同時に収納される
ことになるので、安全上も好ましくない。さらに、水酸
化マグネシウムや水酸化カルシウムを包装材料に添加す
る方法では、酢酸臭の除去はある程度可能であると考え
られるが、本発明者らの検討によると不快感を与える臭
いの主成分は他のものであり、不快臭の低減という点で
はあまり効果のないものであった。そして脱酸素剤を使
用する場合は、滅菌が脱酸素状態で行われるので、細菌
の放射線に対する抵抗性が増加し、同じ滅菌効果を得る
ためにより多くの放射線を照射しなければならなくなり
、けっきょく臭気の低減にはあまり効果がない。In addition, the method of encapsulating gas adsorbent inside the package complicates the packaging process because it requires the process of encapsulating the gas adsorbent, and it also requires that items other than medical devices be stored at the same time, making it safer. I don't like the top either. Furthermore, it is thought that it is possible to remove acetic acid odor to some extent by adding magnesium hydroxide or calcium hydroxide to packaging materials, but according to the inventors' study, the main components of unpleasant odors are other substances. However, it was not very effective in reducing unpleasant odors. And when using oxygen scavengers, sterilization is carried out in deoxidized conditions, which increases the resistance of bacteria to radiation and requires more radiation to be irradiated to achieve the same sterilization effect. It is not very effective in reducing odor.
このように放射線滅菌によって発生する臭気の低減につ
いては決定的な方法がなく、その改良が望まれていた。As described above, there is no definitive method for reducing the odor generated by radiation sterilization, and improvements have been desired.
本発明においては、二酸化珪素および／または酸化亜鉛
を含有するフィルムまたはシートを包装材料として使用
して医療用具を包装することにより、上述した課題を解
決した。すなわち、二酸化珪素および酸化亜鉛を少量包
装材料に含有させるだけで、放射線滅菌によって発生す
る臭気を効率的に消去することができるのである。In the present invention, the above-mentioned problems have been solved by packaging medical devices using a film or sheet containing silicon dioxide and/or zinc oxide as a packaging material. In other words, the odor generated by radiation sterilization can be effectively eliminated by simply including a small amount of silicon dioxide and zinc oxide in the packaging material.
本発明におけるフィルムまたはシート中の二酸化珪素お
よび／または酸化亜鉛の含有量は、０゜０１〜２０重量
％の範囲が適当であり、０．１〜５重量％の範囲が好ま
しい。The content of silicon dioxide and/or zinc oxide in the film or sheet of the present invention is suitably in the range of 0.01 to 20% by weight, preferably in the range of 0.1 to 5% by weight.
本発明においては、フィルムまたはシートに含有される
二酸化珪素および／または酸化亜鉛が放射線滅菌によっ
て発生した臭気を吸収するので、臭気が低減されるもの
と考えられる。しかしながら、これら２つの物質が放射
線滅菌によって発生する臭いに対して特に優れた脱臭効
果を有する理由については明確ではない。In the present invention, silicon dioxide and/or zinc oxide contained in the film or sheet absorbs the odor generated by radiation sterilization, so it is thought that the odor is reduced. However, it is not clear why these two substances have a particularly excellent deodorizing effect on odors generated by radiation sterilization.
本発明においては、二酸化珪素および酸化亜鉛は単独で
使用することもできるし混合して用いることもできる。In the present invention, silicon dioxide and zinc oxide can be used alone or in combination.

明性を要求される場合には、二酸化珪素を単独で使用す
るのが好ましい、また、脱臭効果の点では多孔性の二酸
化珪素が最も優れているので、特に好ましい。However, silicon dioxide rarely impairs the transparency of films or sheets, while zinc oxide impairs transparency even when used in small amounts, so when packaging materials require transparency, It is preferable to use silicon dioxide alone, and porous silicon dioxide is particularly preferable because it has the best deodorizing effect.

Moreover, it can also be used as a laminated film or sheet having a layer containing silicon dioxide and/or zinc oxide as the innermost layer. To package medical devices, a bag or tray is made from a film or sheet, the medical device is stored in the bag, and the bag or tray is sealed using a method such as heat welding.

Examples include. The polymer materials used for these medical devices are mainly polypropylene or polyvinyl chloride, and although the odor generated by radiation sterilization is slightly different between polypropylene and polyvinyl chloride, the packaging material of the present invention It also has an excellent deodorizing effect.
