Description

本発明は、輸液バッグを収納する外装袋と、該外装袋に輸液バッグを収納した輸液バッグユニットに関する。 The present invention relates to an exterior bag that houses an infusion bag and an infusion bag unit that houses the infusion bag in the exterior bag.

特許文献１に、輸液バッグを収納する輸液バッグ用外装袋が開示されている。この輸液バッグ外装袋は、輸液バッグの下端口栓（薬剤排出部）に対向する箇所に易開封性の弱シールからなる下部開口予定部が形成されており、使用時、該下部開口予定部を開封して開口を形成しその開口に口栓を挿通することで、口栓だけを外部に露出させるものである。そのために、特許文献１に記載の外装袋は、使用時に下部開口予定部を引っ張ることで該下部開口予定部の弱シールが容易に剥離するようにしてある。しかし、例えば、外装袋に収納された輸液バッグの輸送時又は取扱い時、下部開口予定部に無理な力が作用すると該下部開口予定部が不用意に開封してしまうおそれがある。 Patent Document 1 discloses an outer bag for an infusion bag that houses an infusion bag. In this infusion bag exterior bag, a lower opening planned portion made of an easy-opening weak seal is formed at a position facing the lower end plug (medicine discharge portion) of the infusion bag. An opening is formed by opening, and the plug is inserted into the opening, so that only the plug is exposed to the outside. Therefore, the exterior bag described in Patent Document 1 is configured such that the weak seal of the planned lower opening is easily peeled off by pulling the planned lower opening at the time of use. However, for example, when an inferior force is applied to the lower opening planned portion during transportation or handling of the infusion bag stored in the outer bag, the lower opening planned portion may be unintentionally opened.

Exterior bag:
The exterior bag 5 is formed by stacking two resin sheets 19 and 21 (a front sheet portion 19 and a back sheet portion 21) processed into a predetermined shape, and a predetermined portion (specifically, the exterior bag) of the resin sheets 19 and 21. 5), the seal or welded portion is formed. Specifically, as shown in FIG. 3 in which the infusion bag 3 and the outer bag 5 are turned upside down, the three edge portions (upper edge and both edges) of the two resin sheets 19 and 21 are thermally welded. Forming the bag 5a having the upper edge seal 23 and the both edge seals 25, then inserting the infusion bag 3 into the bag 5a, and then holding the upper edge side of both edges of the bag 5a, The lower edge seal 27 (see FIG. 1) is formed by thermally welding the (lower edge) 27a. Hereinafter, the lower edge seal is referred to as an “outer seal” as necessary.

外装袋５の樹脂シート１９，２１は、一般には、例えばポリエチレン樹脂からなる多層構造のシートで形成される。また、外装袋５は、上述のように２枚の樹脂シートを重ね合わせて構成してもよいし、一枚の樹脂シートを上縁の位置で折り返して両縁と下縁、また必要であれば上縁を熱溶着することによって構成することもできる。 The resin sheets 19 and 21 of the outer bag 5 are generally formed of a multilayer structure sheet made of, for example, polyethylene resin. Further, the outer bag 5 may be configured by overlapping two resin sheets as described above, or one edge of the resin sheet is folded at the position of the upper edge, and both edges and the lower edge are necessary. For example, the upper edge can be formed by heat welding.

図１に戻り、外装袋５の上縁シール２３の中央には、吊穴２９が形成されている。 Returning to FIG. 1, a suspension hole 29 is formed at the center of the upper edge seal 23 of the outer bag 5.

外装袋５は、外側シール２７の上側に別のシール又は溶着部（案内部）（以下、適宜「内側シール」という。）３１が形成されている。この内側シール３１は、外側シール２７の形成時、表側シート部１９と裏側シート部２１を熱溶着して形成される。 The outer bag 5 has another seal or welded portion (guide portion) (hereinafter referred to as “inner seal”) 31 on the upper side of the outer seal 27. The inner seal 31 is formed by thermally welding the front sheet portion 19 and the back sheet portion 21 when the outer seal 27 is formed.

図１，２に示すように、上下方向に関して内側シール３１と外側シール２７が離間しており、これら内側シール３１と外側シール２７の間に外装体５を横方向に横断する横方向非シール部（非溶着部）３３が形成されている。内側シール３１は、右側シール部（右側溶着部）３５と左側シール部（左側溶着部）３７を有し、これら右側シール部３５と左側シール部３７の間に中央非シール部（口栓進入用非溶着部）３９が形成され、右側シール部３５と左側シール部３７と外側シール２７との間にそれぞれ右側非シール部４１と左側非シール部４３が形成されており、これら右側非シール部４１と左側非シール部４３がそれぞれ横方向非シール部３３の一部を形成している。 As shown in FIGS. 1 and 2, the inner seal 31 and the outer seal 27 are spaced apart from each other in the vertical direction, and a lateral non-seal portion that crosses the exterior body 5 laterally between the inner seal 31 and the outer seal 27. A (non-welded portion) 33 is formed. The inner seal 31 has a right seal part (right weld part) 35 and a left seal part (left weld part) 37, and a central non-seal part (for plug entry) between the right seal part 35 and the left seal part 37. (Non-welded part) 39 is formed, and a right non-seal part 41 and a left non-seal part 43 are formed between the right seal part 35, the left seal part 37 and the outer seal 27, respectively. And the left unsealed portion 43 form part of the lateral unsealed portion 33.

図７に示すように、中央非シール部３９は、輸液バッグシステム１の使用時にそこに輸液バッグ３の口栓１７が進入する箇所である。したがって、中央非シール部３９の左右方向の幅は、該非シール部３９を広げた状態で輸液バッグ３の口栓１７が容易に通過できる大きさとする。 As shown in FIG. 7, the central non-seal portion 39 is a place where the plug 17 of the infusion bag 3 enters when the infusion bag system 1 is used. Therefore, the width in the left-right direction of the central non-seal part 39 is set to a size that allows the spigot 17 of the infusion bag 3 to easily pass in a state where the non-seal part 39 is expanded.

実施の形態では右側シール部３５と左側シール部３７の外側端部は外装袋５の両縁シール２５に繋がっているが、右側シール部３５と左側シール部３７の外側端部は両側縁シール２５に繋がっていなくてもよい。また、図示しないが、右側シール部３５と左側シール部３７は複数の小シール部に分割してもよい。小シール部の配置は任意で、例えば、横方向に一列に所定の間隔をあけて一列又は複数列に配置してもよい。 In the embodiment, the outer end portions of the right seal portion 35 and the left seal portion 37 are connected to both edge seals 25 of the exterior bag 5, but the outer end portions of the right seal portion 35 and the left seal portion 37 are both side edge seals 25. It does not have to be connected to. Although not shown, the right seal part 35 and the left seal part 37 may be divided into a plurality of small seal parts. Arrangement | positioning of a small seal | sticker part is arbitrary, for example, you may arrange | position to 1 row or several rows at predetermined intervals in 1 row in the horizontal direction.

右側シール部３５と左側シール部３７の上縁４５，４７は、図１，２に示すように、水平方向に伸ばしてもよいし、図８に示すように、外装袋５の内部に収容された輸液バッグ３の対向箇所、すなわち、図１に示すように口栓１７から両側に伸びる肩部４９の傾斜角と同じ又はほぼ同じ角度としてもよい。図２に示すように、上縁と異なり、右側シール部３５と左側シール部３７の下縁５１，５３の形状は違っている。具体的に、本実施形態では、右側シール部３５と左側シール部３７の下縁５１，５３は共に図の右側から左側に向かって下方（外側シール側）に傾斜しており、右側シール部３５の下縁内側端部（角部）５５が左側シール部３７の下縁内側端部（角部）５７よりも低くなっている。 The upper edges 45 and 47 of the right seal part 35 and the left seal part 37 may extend in the horizontal direction as shown in FIGS. 1 and 2 and are accommodated in the exterior bag 5 as shown in FIG. Further, the opposite position of the infusion bag 3, that is, the angle of inclination of the shoulder 49 extending from the plug 17 to both sides as shown in FIG. As shown in FIG. 2, unlike the upper edge, the shapes of the lower edges 51 and 53 of the right seal part 35 and the left seal part 37 are different. Specifically, in this embodiment, the lower edges 51 and 53 of the right seal part 35 and the left seal part 37 are both inclined downward (outer seal side) from the right side to the left side of the figure, and the right seal part 35 The lower edge inner end portion (corner portion) 55 is lower than the lower edge inner end portion (corner portion) 57 of the left seal portion 37.

右側シール部３５の近傍に位置する右縁シール２５の下端寄り外縁であって外側シール２７と内側シール３１の間には、略Ｖ形状又は略Ｕ形状の切り込み（ノッチ）５９が形成されており、この切り込み５９を始端として横方向非シール部３３を横方向に横断する引き裂き線（破断線）６１を形成することで、外側シール２７を含む外装袋５の下端部６３（図６参照）を引き裂いて分離できるようにしてある。 A substantially V-shaped or substantially U-shaped notch 59 is formed between the outer seal 27 and the inner seal 31 at the outer edge near the lower end of the right edge seal 25 located in the vicinity of the right seal portion 35. By forming a tear line (break line) 61 transversely across the lateral non-seal portion 33 starting from the notch 59, the lower end 63 (see FIG. 6) of the outer bag 5 including the outer seal 27 is formed. It can be torn and separated.

図２に示すように、切り込み５９から始まる引き裂き線（破断線）６１が横方向非シール部３３内に収まるように、左側シール部３７と右側シール部３５には種々の工夫がなされている。具体的に説明すると、引き裂きに関して、２枚の樹脂シートを熱溶着してなるシール部はこれら２枚のシートが一体となって引き裂きに抵抗するため、熱溶着されていない非シール部に比べて熱溶着されたシール部はより大きな引き裂き強度（抵抗力）を発揮するという性質を利用している。そして、右側シール部３５の下縁５１は、切り込み５９に近い右側から反対側の左側に向かって次第に外側シール２７に近づくように下方に傾斜しており、切り込み５９から始まった引き裂き線６１が上方（外側シール２７から離れる方向）にずれた場合でも、その引き裂き線６１が右側シール部３５の下縁５１に案内されながら左側に進行するようにしてある。また、右側シール部下縁５１の内側端部５５は、左側シール部下縁５３の内側端部５７よりも外側シール２７寄りに位置しており、右側シール部３５を通過して中央非シール部３９に進入した引き裂き線６１が多少上方にずれた場合でも該引き裂き線６１の先端が左側シール部下縁５３に当たるようにしてある。さらに、左側シール部下縁５３は、右側から左側に向かって次第に外側シール２７に近づくように傾斜しており、引き裂き線６１の先端が左側シール部下縁５３に案内されながら、左側シール部３７と外側シール２７の間の領域を進行するようにしてある。 As shown in FIG. 2, various measures are taken on the left seal portion 37 and the right seal portion 35 so that the tear line (break line) 61 starting from the notch 59 is accommodated in the lateral non-seal portion 33. Specifically, regarding the tearing, the seal portion formed by thermally welding two resin sheets resists tearing as a result of the two sheets being integrated together, and therefore, compared to a non-sealed portion that is not thermally welded. The heat-sealed seal portion utilizes the property of exhibiting a greater tear strength (resistance force). The lower edge 51 of the right seal portion 35 is inclined downward so as to gradually approach the outer seal 27 from the right side close to the notch 59 toward the left side on the opposite side, and the tear line 61 starting from the notch 59 is upward. Even in the case of deviation in the direction away from the outer seal 27, the tear line 61 proceeds to the left while being guided by the lower edge 51 of the right seal portion 35. Further, the inner end portion 55 of the right seal portion lower edge 51 is positioned closer to the outer seal 27 than the inner end portion 57 of the left seal portion lower edge 53, and passes through the right seal portion 35 to the central non-seal portion 39. Even when the entering tear line 61 is slightly shifted upward, the tip of the tear line 61 is made to contact the lower edge 53 of the left seal portion. Furthermore, the left seal portion lower edge 53 is inclined so as to gradually approach the outer seal 27 from the right side toward the left side, and the tip of the tear line 61 is guided to the left seal portion lower edge 53 while the left seal portion 37 and the outer side The region between the seals 27 is advanced.

４．使用：
このように構成された輸液バッグシステム１の使用について説明する。図４に示すように、使用時、ユーザは、左手と右手でそれぞれ、切り込み５９を挟んでその上側と下側に位置する外装袋部分を把持し、切り込み５９から右側非シール部４１に向かって該右側非シール部４１に位置する表側と裏側のシート部１９，２１を引き裂く。このとき、左右の手に加える力の加減によって、引き裂き線６１は上側又は下側（内側シール３１側又は外側シール２７側）にずれる。例えば、引き裂き線６１が上側（内側シール３１側）にずれた場合、引き裂き線６１の先端は右側シール部３５に捕まり、この右側シール部３５の下縁５１に沿って進行する。逆に、引き裂き線６１が下側（外側シール２７側）にずれた場合、引き裂き線６１の先端は外側シール２７に捕まり、この外側シール２７の上縁に沿って進行する。 4). use:
The use of the infusion bag system 1 configured as described above will be described. As shown in FIG. 4, in use, the user grips the outer bag portion positioned on the upper side and the lower side with the left hand and the right hand sandwiched between the left hand and the right hand, and from the cut 59 toward the right non-seal part 41. The sheet parts 19 and 21 on the front side and the back side located in the right non-seal part 41 are torn. At this time, the tear line 61 is shifted to the upper side or the lower side (the inner seal 31 side or the outer seal 27 side) by adjusting the force applied to the left and right hands. For example, when the tear line 61 is displaced upward (on the inner seal 31 side), the tip of the tear line 61 is caught by the right seal part 35 and proceeds along the lower edge 51 of the right seal part 35. Conversely, when the tear line 61 is shifted downward (outer seal 27 side), the tip of the tear line 61 is caught by the outer seal 27 and proceeds along the upper edge of the outer seal 27.

図５に示すように、右側非シール部４１の間を通過した後、引き裂き線６１は中央非シール部３９に進入する。図示するとおり、中央非シール部３９の上側（外側シール２７の反対側）には引き裂き線６１が上側に移動するのを規制する構成が無いため、引き裂き線６１は外側シール２７から次第に離れて上方に移動することがある。この場合、左側シール部下縁５３の内側端部５７が右側シール部下縁５１の内側端部５５よりも上方（外側シール２７から離れる方向）に位置しているため、引き裂き線６１の先端が多少上方に移動しても該引き裂き線６１が左側シール部３７の上側に逸れることはない。 As shown in FIG. 5, the tear line 61 enters the central non-seal part 39 after passing between the right non-seal part 41. As shown in the drawing, the upper side of the central non-seal portion 39 (opposite side of the outer seal 27) is not configured to restrict the tear line 61 from moving upward. May move to. In this case, since the inner end 57 of the left seal portion lower edge 53 is located above the inner end 55 of the right seal portion lower edge 51 (in the direction away from the outer seal 27), the tip of the tear line 61 is slightly above The tear line 61 does not deviate to the upper side of the left seal portion 37 even if it moves to.

図５，６に示すように、引き裂き線６１はさらに、中央非シール部３９を通過し、左側非シール部４３に進入し、左側シール部３７と外側シール２７に規制されながら左側非シール部４３を通過し、左縁シール２５を横断して、外側シール２７と内側シール３１との間で外装袋５の下端部６３を分離する。 As shown in FIGS. 5 and 6, the tear line 61 further passes through the central non-seal part 39, enters the left non-seal part 43, and is regulated by the left seal part 37 and the outer seal 27 while being left unseal part 43. And the lower edge 63 of the outer bag 5 is separated between the outer seal 27 and the inner seal 31 across the left edge seal 25.

図７に示すように、この状態で、輸液バッグ３の口栓１７を中央非シール部３９に進入し、また中央非シール部３９を介して外部に露出させる。次に、外装袋５の上縁シール２３に設けた吊穴２９に吊具６９を通し、口栓１７に針（図示せず）を刺して、輸液７（図１参照）を供給する。 As shown in FIG. 7, in this state, the stopper 17 of the infusion bag 3 enters the central non-seal part 39 and is exposed to the outside through the central non-seal part 39. Next, the suspension tool 69 is passed through the suspension hole 29 provided in the upper edge seal 23 of the outer bag 5, and a needle (not shown) is pierced into the plug 17 to supply the infusion solution 7 (see FIG. 1).

このように、上述の実施形態に係る外装袋及び輸液バッグシステムによれば、輸液バッグの輸送時又は取扱い時に外装袋に無理な力が作用しても容易にシールが破れて開封してしまうということがない。また、開封時、切り込み５９から始まった引き裂き線が力の入れ方によって内側シールに向かってずれることがあっても、引き裂き線は内側シールに案内されながら横方向非シール部を進行し、外装袋の下部領域を確実に横断する。さらに、切り込みから離れた一方のシール部（上述の実施形態では左側シール部）の内側端部が切り込みに近い他方のシール部（上述の実施形態では右側シール部）の内側端部よりも上方（外側シールから離れる方向）に配置されているので、切り込みから始まって一方のシール部の下を通過した引き裂き線は確実に他方のシール部の下縁に到達する。したがって、一方のシール部を通過した引き裂き線の先端が中央非シール部を通過して他方のシール部の上方に入ることがない。 Thus, according to the exterior bag and infusion bag system concerning the above-mentioned embodiment, even if an excessive force acts on the exterior bag at the time of transportation or handling of the infusion bag, the seal is easily broken and opened. There is nothing. Further, even when the tear line starting from the notch 59 may be displaced toward the inner seal when the force is applied at the time of opening, the tear line advances through the non-sealed portion in the lateral direction while being guided by the inner seal. Make sure to cross the lower area. Furthermore, the inner end of one seal part (left side seal part in the above-described embodiment) away from the notch is above the inner end part of the other seal part (right side seal part in the above-described embodiment) close to the notch ( Therefore, the tear line starting from the notch and passing under one of the seal portions surely reaches the lower edge of the other seal portion. Therefore, the tip of the tear line that has passed through one seal part does not pass through the central non-seal part and enter above the other seal part.

５．他の形態：
上述した実施形態は本発明の一例であって、上述した実施形態を種々改変した形態も本発明の技術範囲に含まれる。例えば、上述の実施形態では、右側シール部下縁５１と左側シール部下縁５３は共に右側から左側（切り込み５９から離れる方向）に向かって次第に外側シール２７に近づくように傾斜しているが、両下縁５１，５３は外装袋５の横断方向（引き裂き方向）に平行又はほぼ平行であってもよいし、いずれか一方のみが同方向に傾斜していてもよい。なお、図９は、右側シール部下縁５１を傾斜させ、左側シール部下縁５５は横断方向に平行又はほぼ平行にした例である。 5. Other forms:
The above-described embodiment is an example of the present invention, and various modifications of the above-described embodiment are also included in the technical scope of the present invention. For example, in the above-described embodiment, both the right seal portion lower edge 51 and the left seal portion lower edge 53 are inclined so as to gradually approach the outer seal 27 from the right side to the left side (the direction away from the notch 59). The edges 51 and 53 may be parallel or substantially parallel to the transverse direction (tear direction) of the outer bag 5, or only one of them may be inclined in the same direction. FIG. 9 is an example in which the right seal portion lower edge 51 is inclined and the left seal portion lower edge 55 is parallel or substantially parallel to the transverse direction.

また、図１０に示すように、中央非シール部３９には、右側から左側（切り込み５９から離れる方向）に向かって下方（外側シール側）に傾斜した直線状溶着部（補強部）６５を左右一列に配置し、右側から左側に向かって進行する引き裂き線６１を外側シール２７に向けて案内するようにしてもよい。溶着部（案内部）６５は、内側シール３１及び外側シール２７を形成する際に該溶着部（案内部）６５に対応する箇所で表側と裏側のシート部１９，２１を溶着することによって形成できる。溶着部（補強部）６５に代えて、溶着部（補強部）６５が位置する箇所の表側又は裏側シート部部分に脆弱部を形成し、これにより右側から左側に向かって進行する引き裂き線６１を外側シール２７に向けて案内するようにしてもよい。この場合、脆弱部は、例えば表側又は裏側シートが積層シートで構成されている場合、積層前に少なくとも一枚のシートに図示する模様の複数の穴を開けることで形成することができる。 Further, as shown in FIG. 10, the central non-seal portion 39 is provided with a linear welded portion (reinforcing portion) 65 inclined downward (outer seal side) from the right side to the left side (direction away from the notch 59). The tear lines 61 arranged in a line and proceeding from the right side to the left side may be guided toward the outer seal 27. The welding part (guide part) 65 can be formed by welding the front and back sheet parts 19 and 21 at locations corresponding to the welding part (guide part) 65 when forming the inner seal 31 and the outer seal 27. . Instead of the welded part (reinforcing part) 65, a fragile part is formed on the front side or the back side sheet part where the welded part (reinforcing part) 65 is located. You may make it guide toward the outer side seal | sticker 27. FIG. In this case, for example, when the front side sheet or the back side sheet is composed of a laminated sheet, the fragile portion can be formed by making a plurality of holes having a pattern illustrated in at least one sheet before lamination.

さらに、図１１に示すように、内側シール３１を下方に伸ばして外側シール２７に接続する一方、内側シール３１には右側から左側（切り込み５９から離れる方向）に向かって引き裂き線を案内する複数の脆弱部（非溶着部、案内部）６７を形成してもよい。なお、各脆弱部６７の形状は、限定的ではないが、図示するくの字形とし、これらくの字状の脆弱部６７を該くの字形状の中央部を切り込み５９から離れる方向に向けて右側と左側のシール部４１，４３に等間隔に配置することが好ましい。この場合も、切り込み５９から始まる引き裂き線が確実に内側シールを横方向に横断し、外装袋の下端部を分離できる。 Further, as shown in FIG. 11, the inner seal 31 extends downward and is connected to the outer seal 27, while the inner seal 31 has a plurality of guide lines that guide tear lines from the right side to the left side (in the direction away from the notch 59). A fragile portion (non-welded portion, guide portion) 67 may be formed. The shape of each fragile portion 67 is not limited. However, the fragile portion 67 is a U-shape shown in the drawing, and the fragile portion 67 having the U-shape is directed toward the direction away from the notch 59 at the center of the U-shape. It is preferable to arrange the seal portions 41 and 43 on the right and left sides at equal intervals. In this case as well, the tear line starting from the notch 59 can surely cross the inner seal in the lateral direction, and the lower end of the outer bag can be separated.
