A plurality of types of vents with different sheath shapes can be formed, but the same size and shape of vents can be provided on the entire surface of the laminated sheet because the temperature can be easily controlled by the number of tube folds. It is preferable to form at intervals.

本発明の発熱袋おいては、偏平状の袋の片面の表面に、チューブをさらに密着保持するための粘着剤部を設けることができる。粘着剤部の配置位置や大きさ等については特に制限されることがなく、例えば、包装材の全面、中央部、周辺部、または一部分に、適宜大きさや形状が同一である粘着剤部、または大きさや形状が異なる複数種類の粘着剤部を形成することができるが、包装材の全面に、大きさ及び形状が同一である粘着剤部を等間隔に形成することが好ましい。粘着剤部の片面の包装材全体に対する面積の割合は、通常は2〜50%、好ましくは5〜20%である。   In the heat generating bag of the present invention, an adhesive part for further tightly holding the tube can be provided on the surface of one side of the flat bag.

しかしながら、本発明の発熱袋を輸液の加温のために使用する場合は、好ましい発熱特性を発揮させるために、包装材として一方の片面と他の一方の片面のJISK7129A法による水蒸気透過度の合計が、500〜1200g/m・24hr、好ましくは600〜1000g/m・24hrとなるように選択される。例えば一方の片面に非通気性の包装材を用いた場合は、他の一方の片面の包装材の水蒸気透過度は500〜1200g/m・24hrとなり、両面に同一の包装材を用いた場合は、その包装材の水蒸気透過度は250〜600g/m・24hrとなる。 However, when the exothermic bag of the present invention is used for warming an infusion solution, in order to exhibit preferable exothermic characteristics, the total water vapor permeability according to the JISK7129A method on one side and the other one side as a packaging material. but, 500~1200g / m 2 · 24hr, preferably chosen such that 600~1000g / m 2 · 24hr. For example, when a non-breathable packaging material is used on one side, the water vapor permeability of the other one side is 500 to 1200 g / m 2 · 24 hr, and the same packaging material is used on both sides. The water vapor permeability of the packaging material is 250 to 600 g / m 2 · 24 hr.

Within 3 minutes (time after contacting the exothermic composition with oxygen in the air), and 1 to 4 hours to keep the infusion at a temperature around body temperature. (Time required for infusion of the infusion solution) can be easily achieved. If the water vapor transmission rate is set to be smaller than the above range, the initial temperature rise (rise) may be delayed or may not reach a temperature around the body temperature, and the water vapor transmission rate may be larger than the above range. When set, the initial temperature rise (rise) is accelerated, but the temperature holding time around the body temperature is shortened.

A breathable packaging material was produced by uniformly providing a large number of needle holes in a bonded packaging material made of a commercially available polyethylene film and nylon film. This breathable packaging material had a water vapor permeability of 600 g / m 2 · 24 hr according to the JIS K7129A method.
Moreover, the adhesive part uniformly disperse | distributed was provided in the nylon film side of the said bonding packaging material. This packaging material had reduced air permeability due to the pressure-sensitive adhesive part, and had a water vapor permeability of 300 g / m 2 · 24 hr according to the JISK7129A method.

また、窒素ガス雰囲気下で、鉄粉が62wt%、活性炭が8wt%、食塩(無機電解質)が2wt%、水が20wt%、保水剤が8wt%となるように混合して発熱組成物を調製した。前記の2種類の通気性包装材を100mm×150mmに切断し、各1枚ずつを熱融着面が互いに内側となるようにして重ね合せ、周辺を加熱融着して袋状に成形するとともに、発熱組成物45gを充填して図1(1)に示すような発熱袋を製作した。さらに、発熱袋の対向する2辺の貼り合せ部に、図2に示すような円形の貫通部(内径5mm)を合計10箇所設けた。その後、発熱袋を120mm×180mmの非通気性の偏平状袋に密封した。   Also, in a nitrogen gas atmosphere, an exothermic composition is prepared by mixing so that the iron powder is 62 wt%, the activated carbon is 8 wt%, the salt (inorganic electrolyte) is 2 wt%, the water is 20 wt%, and the water retention agent is 8 wt%. did. The two kinds of breathable packaging materials are cut into 100 mm × 150 mm, and each one is overlapped so that the heat-sealing surfaces are inside, and the periphery is heat-fused to form a bag shape. The exothermic bag as shown in FIG. 1 (1) was manufactured by filling 45 g of the exothermic composition. Furthermore, a total of 10 circular through portions (inner diameter: 5 mm) as shown in FIG. Thereafter, the heating bag was sealed in a 120 mm × 180 mm non-breathable flat bag.

(輸液の加温試験)
前記の発熱袋の製作において、貫通部を設けなかったほかは、前記と同様にして発熱袋を製作し、同様に非通気性の偏平状袋に密封した。
20℃の室内に、貫通部を設けた発熱袋、及び貫通部を設けなかった発熱袋を1昼夜放置した。次に、20℃の室内でこれらの発熱袋を非通気性の偏平状袋から取り出すとともに、貫通部を設けた発熱袋に、図9に示すように輸液チューブを通し、さらに他の発熱袋を輸液チューブが挟持されるように側面に重ねて固定した。非通気性の偏平状袋から発熱袋を取り出してから5分後、輸液バッグから前記の輸液チューブに3cc/minの流量で20℃の輸液を流通し、発熱袋に挟持された輸液チューブを通過した輸液の温度を約5分後毎に測定した。その結果、2時間にわたり30〜32℃の輸液が得られた。
(Infusion warming test)
In the production of the heat-generating bag, a heat-generating bag was produced in the same manner as described above except that no through portion was provided, and was similarly sealed in a non-breathable flat bag.
A heat generating bag provided with a penetrating part and a heat generating bag not provided with a penetrating part were left overnight in a room at 20 ° C. Next, these heat generation bags are taken out from the non-breathable flat bag in a room at 20 ° C., and an infusion tube is passed through the heat generation bag provided with the penetrating portion as shown in FIG. It was piled up and fixed to the side so that an infusion tube might be pinched. Five minutes after taking out the heating bag from the non-breathable flat bag, the infusion solution was passed through the infusion tube at a flow rate of 3 cc / min from the infusion bag at a flow rate of 20 ° C. and passed through the infusion tube sandwiched between the exothermic bags. The temperature of the infusion solution was measured about every 5 minutes. As a result, an infusion solution at 30 to 32 ° C. was obtained over 2 hours.

(発熱袋の製作)
実施例1の発熱袋の製作において、貫通部の替わりに凸部を設けたほかは実施例1と同様にして、図4に示すような四角柱の凸部(縦5mm、横5mm、高さ3mm)を合計10個有する発熱袋を製作した。次に、全ての凸部の先端の面に粘着剤部を設け、離型紙を貼り合せた。その後、発熱袋を120mm×180mmの非通気性の偏平状袋に密封した。
(Production of fever bag)
In the production of the heat generating bag of Example 1, a rectangular column as shown in FIG. 4 (vertical 5 mm, horizontal 5 mm, height, as in Example 1 except that a convex portion was provided instead of the penetrating portion. A heating bag having a total of 10 3 mm) was produced. Next, the adhesive part was provided in the surface of the front-end | tip of all the convex parts, and the release paper was bonded together. Thereafter, the heating bag was sealed in a 120 mm × 180 mm non-breathable flat bag.

(輸液の加温試験)
20℃の室内に、前記の発熱袋2袋を1昼夜放置した。次に、20℃の室内でこれらの発熱袋を非通気性の偏平状袋から取り出し、離型紙を剥がして、凸部を有する面が互いに内側となるようにして重ね合せ、凸部の先端の面同士を接着するとともに、凸部で折り返すようにチューブを蛇行状に通した。非通気性の偏平状袋から発熱袋を取り出してから5分後、輸液バッグから前記の輸液チューブに3cc/minの流量で20℃の輸液を流通し、発熱袋に挟持された輸液チューブを通過した輸液の温度を約5分後毎に測定した。その結果、2時間にわたり30〜32℃の輸液が得られた。
(Infusion warming test)
In the room at 20 ° C., the two exothermic bags were left for one day. Next, these heat-generating bags are taken out from the non-breathable flat bag in a room at 20 ° C., and the release paper is peeled off and overlapped so that the surfaces having the convex portions are inside each other. While bonding the surfaces, the tube was passed in a meandering manner so as to be folded back at the convex portion. Five minutes after taking out the heating bag from the non-breathable flat bag, the infusion solution was passed through the infusion tube at a flow rate of 3 cc / min from the infusion bag at a flow rate of 20 ° C. and passed through the infusion tube sandwiched between the exothermic bags. The temperature of the infusion solution was measured about every 5 minutes. As a result, an infusion solution at 30 to 32 ° C. was obtained over 2 hours.
