PROBLEM TO BE SOLVED: To allow certain maintenance of a liquid medicine such as an insulin put in a pen type syringe at room temperature, and allowing easy achievement by only storing the pen type syringe in a thermos bottle marketed or present at home.SOLUTION: A pen type syringe has an outside diameter capable of being inserted into a cylindrical portable thermos bottle, a buffer cylinder having a cylindrical hole in which a liquid medicine side of the pen type syringe is positioned in the center of a holder is produced of a foamed resin, and the pen type syringe is inserted into the portable thermos bottle, so that the pen type syringe is not damaged by colliding with a hard inner wall of the thermos bottle, and an insulin thereinside is cold-insulated because a space is cooled by a cold insulator. Because disposing the cold insulator in the outer circumference of a heat insulation cylinder having a cylindrical hole into which an injection button side of the pen type syringe is inserted, the problem in which the pen type syringe directly contacts with the cold insulator to excessively cool the pen type syringe.COPYRIGHT: (C)2014,JPO&INPIT【課題】ペン型の注射器に入ったインスリンなどの薬液を確実に室温に維持でき、しかも市販や家庭に有る魔法瓶に収納するだけで簡易に実現可能とする。【解決手段】円筒状の携帯魔法瓶に挿入可能な外径を有し、ペン型注射器の薬液側がホルダーの中央に来る円筒状孔を有する緩衝筒を発泡樹脂で製造して、前記携帯魔法瓶に挿入するので、ペン型注射器が魔法瓶の硬い内壁に衝突して損傷することはなく、かつ空間は保冷剤で冷却されるので、内部のインスリンも保冷される。また、前記ペン型注射器の注入ボタン側を挿入する筒状孔を有する断熱筒の外周に保冷剤を配設するので、ペン型注射器が直接に保冷剤と接して、冷やし過ぎるという問題も生じない。【選択図】図1
