PROBLEM TO BE SOLVED: To provide a protective cover which is easily adaptable to a plurality of kinds of artificial lung bodies having sizes different in thickness.SOLUTION: A protective cover 23 is attached to cover at least a part of an artificial lung body 22. The protective cover includes first and second frames 24, 25, one of which is arranged on the front surface of the artificial lung and the other on the rear surface thereof. The first frame has a pair of right-left fitting pieces 26 each extending to the second frame when the cover is attached to the artificial lung body, which are formed on upper and lower ends, respectively. Engagement claws 27 are formed on the front end of the engagement claws. The second frame has shoulder portions 28 extending toward the first frame when the cover is attached to the artificial lung body, respectively, on upper and lower ends. The shoulder portions each have a pair of right-left engagement holes arranged in accordance with the engagement claws and equipped with the engagement claws so that the engagement claws can be engaged, respectively. The engagement holes of the second frame includes a plurality of rows of pair of right-left engagement holes 29, 30 which are different in distance from the first frame.COPYRIGHT: (C)2014,JPO&INPIT【課題】厚さの異なる複数種類のサイズの人工肺本体に対して容易に適合させることが可能な保護カバーを提供する。【解決手段】人工肺本体22の少なくとも一部を覆うように装着される保護カバー23であって、人工肺本体に対して、いずれか一方が前面側に他方が後面側にそれぞれ配置される第1及び第2枠体24、25を備える。第1枠体は、上下端部に各々、人工肺本体への装着状態において第2枠体に向かって延びる左右一対の係合片26を有し、係合片の先端には係合爪27が設けられ、第2枠体は、上下端部に各々、人工肺本体への装着状態において第1枠体に向かって延びる肩部28を有し、肩部には、係合爪に対応させて配置され係合爪の各々が嵌合可能なように設けられた左右一対の係合穴を有する。第2枠体の係合穴は、第1枠体からの距離が異なる複数列の左右一対の係合穴29、30を含む。【選択図】図5
