【考案の詳細な説明】
本考案は、注射器等の器具、人工腎臓等の透析器のよう
に滅菌の必要がある内容物を収容する滅菌用袋に関する
ものである。[Detailed Description of the Invention] The present invention relates to a sterilization bag for storing contents that need to be sterilized, such as instruments such as syringes and dialysis machines such as artificial kidneys.
特に透析器のような大きく重量のある内容物に適した滅
菌用袋に関するものである。In particular, the present invention relates to a sterilization bag suitable for large and heavy contents such as a dialysis machine.
従来から医療器具の包装用袋として、第１図に示される
ように合成樹脂フィルムの一部に孔を設け、その部分を
透気性材料で覆った袋、第２図に示すように合成樹脂フ
ィルムを折り、その両端が重なり合わないように突き合
せ、それらを透気性材料で貼り合せた袋、また第３図に
示すように筒状体で開口している一方端が他方より長く
なっている間に透気性材料をはさむように貼着してなる
袋があった。Conventionally, bags for packaging medical devices have been used, such as bags made of a synthetic resin film with holes made in a part and covered with an air-permeable material as shown in Figure 1, and synthetic resin films as shown in Figure 2. A bag is made by folding a bag, butting the two ends together so that they do not overlap, and pasting them together with an air-permeable material.As shown in Figure 3, the bag is made of a cylindrical body with one open end longer than the other. There was a bag with a permeable material sandwiched between them.
しかしながら第１図唱よび第２図の袋は、孔またはすき
間が狭いと、通気性が十分でなく袋が滅菌時に破れたり
、内部に残存ガスがあり好ましくなかった。However, in the bags shown in Figures 1 and 2, if the holes or gaps are narrow, the air permeability is insufficient and the bag may tear during sterilization, or there may be residual gas inside, which is undesirable.
これらを防ぐため孔またはすき間を大きくすると、透気
性は太きくなるが、透気性材料の部分が大きくなり、機
械的強度が十分でなくなってしまう相矛盾した問題が生
じてしまう。If the holes or gaps are made larger in order to prevent these problems, the air permeability will increase, but the area of the air permeable material will also become larger, leading to the contradictory problem of insufficient mechanical strength.
特に透析器のような大きな重量のある内容物について問
題となる。This is particularly a problem with large and heavy contents such as dialyzers.
また第３図の袋は、袋の構造上平らな形状となるため器
具の大きさに応じて袋の寸法を変えなければならないう
え、内容物の荷重が合成樹脂フィルムと透気性材料との
接着部分にかかった場合、剥離方向が９０°方向になる
ため、重量のあるものまたは容量の大きいものには適さ
ないものであった。In addition, the bag shown in Figure 3 has a flat shape due to its structure, so the dimensions of the bag must be changed depending on the size of the device, and the load of the contents is due to the bond between the synthetic resin film and the air permeable material. If it touches a portion, the peeling direction is 90°, which makes it unsuitable for heavy items or large capacity items.
本考案は、上記従来の滅菌用袋の欠点を鑑み改良したも
のであって、重量があり、容量が大きい器具の包装に適
し、しかも合成樹脂フィルムと透気性材料との接着部の
剥離の釦それがない滅菌用袋である。The present invention has been improved in view of the drawbacks of the conventional sterilization bags mentioned above, and is suitable for packaging heavy and large-capacity instruments, and also has a button for peeling off the bond between the synthetic resin film and the air-permeable material. It is not a sterilization bag.
以下図面に従い本考案を詳細に説明する。The present invention will be described in detail below with reference to the drawings.
本考案は、第４図および第５図に示すように内側が熱接
着性を有する積層フィルムからなる２枚の基材からなる
胴部１の一端に２つ折りにした通気性材料２が胴部の外
側に露出しないように折部３が内方になるように挿入す
る。In the present invention, as shown in FIGS. 4 and 5, a breathable material 2 folded in half is attached to one end of a body 1 made of two base materials made of a laminated film with thermal adhesive properties on the inside. Insert so that the folded part 3 is inward so that it is not exposed to the outside.
次に挿入した通気性材料２０両端４，５の外側を胴部の
内壁に接着し、かつ通気性材料の一方の折返部６を折部
３の付近で胴部内壁に不連続シール７をすると共に胴部
の両側訃よび通気性材料の挿入部分と反対側の端部を熱
シールしてなる滅菌用袋である。Next, the outer sides of both ends 4 and 5 of the inserted breathable material 20 are glued to the inner wall of the body, and one folded part 6 of the breathable material is discontinuously sealed 7 on the inner wall of the body near the folded part 3. It is also a sterilization bag made by heat-sealing both ends of the body and the end opposite to the insertion part of the breathable material.
ここで本考案の滅菌用袋の胴部の材料は、ポリエチレン
、エチレン−酢酸ビニル共重合体、ポリプロピレン等の
熱接着性を有する材料とナイロン、ポリエチレンテレフ
タレート、延伸ポリプロピレン等の不透気性フィルムと
の積層フィルムからなる。Here, the material of the body of the sterilization bag of the present invention is a combination of a thermal adhesive material such as polyethylene, ethylene-vinyl acetate copolymer, and polypropylene, and an air-impermeable film such as nylon, polyethylene terephthalate, and stretched polypropylene. Consists of laminated film.
また通気性材料は、不織布、紙等の材料で、特に熱シー
ル性を有する通気性材料を用いるのが好ましい。Further, the breathable material is a material such as a nonwoven fabric or paper, and it is particularly preferable to use a breathable material having heat sealability.
紙の場合は、表面にヒートシールラッカー等を塗布して
使用する。In the case of paper, apply heat seal lacquer or the like to the surface.
熱シール性を有する不織布としては、タイベック１０５
９Ｂ、 タイベック１０７３Ｂ（いずれもデュポン社製
）、ＭＴフォーマ−（三木特種製紙製）、ＧＬ（輿入製
）がある。Tyvek 105 is a nonwoven fabric with heat sealability.
9B, Tyvek 1073B (all manufactured by DuPont), MT Former (manufactured by Miki Tokushu Paper), and GL (manufactured by Koshiiri).
本考案は、上記のような構成からなるので、大きな器具
を包装した場合、通気性材料の部分が開いた状態になる
ので、従来の袋の大きさに比較して全体に小さくするこ
とができる。The present invention has the above-mentioned structure, so when a large instrument is packaged, the breathable material part is left open, so the overall size of the bag can be made smaller compared to the size of conventional bags. .
また通気性材料の面積が大きいので滅菌時に破袋するお
それがないうえ、胴部と通気性材料のシール部８，９の
内面をシールすれば、滅菌後再汚染されるおそれがなく
なる。Furthermore, since the area of the breathable material is large, there is no risk of the bag breaking during sterilization, and if the body and the inner surfaces of the seal parts 8 and 9 of the breathable material are sealed, there is no risk of recontamination after sterilization.
さらに胴部と通気性材料の接着部分に荷重がかカッてモ
、１８００方向に剥離するようになるので、剥離し難く
なる。Furthermore, as the load is applied to the bonded portion between the body and the breathable material, the bond will peel in the 1800 direction, making it difficult to separate.
例えば胴部の材料として延伸ポリプロピレンフィルム（
２５μ）／ポリエチレンフィルム（８０μ）、透気性材
料としてタイベック１７０３Ｂを用いて、第３図および
第４，５図の袋の製造し、接着部分の接着強度を比較し
た。For example, stretched polypropylene film (
Bags shown in FIGS. 3, 4, and 5 were manufactured using Tyvek 1703B as the air-permeable material, and the adhesive strength of the bonded portions was compared.
従来の袋の第３図の場合１．１ Ｋｇ／ １５ ｒｒｒ
ｍであったのに対して本考案の第４，５図の袋の場合２
．４Ｋｇ／ １５ ｒｒａｎであった。In the case of conventional bag Figure 3: 1.1 Kg/ 15 rrr
m, whereas in the case of the bag shown in Figures 4 and 5 of the present invention, 2
．． It was 4Kg/15 rran.
しかも本考案の袋は、折返部の一方のみ折部付近を不連
続シールをしているので、大きい内容物を入れても通気
性材料が外側に押出されるおそれがないうえ、不連続シ
ールであるので通気性の障害がおこらないものである。In addition, the bag of the present invention has a discontinuous seal near the fold on only one side of the fold, so there is no risk of the breathable material being pushed outward even when large contents are placed, and the bag has a discontinuous seal. Therefore, there is no problem with ventilation.
