PROBLEM TO BE SOLVED: To attach/detach two terminals and connect them at strong adhesion, while improving operability by constituting them into simple structures.SOLUTION: A connection adapter 10 connects between an outflow terminal 20 capable of delivering liquid diet and an inflow terminal 42. The connection adapter 10 comprises a cylindrical body 60, and a through-hole 62 formed to penetrate inside the cylindrical body 60 along the axial direction of the cylindrical body 60. The cylindrical body 60 includes: an upstream-side installation part 70 retained closely to the outflow terminal 20 and a downstream-side installation part 72 retained closely to the inflow terminal 42. Durometer hardnesses of the respective installation parts 70 and 72 are set within a range of 60-90.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】簡単な構造に構成することにより、操作性を向上させながら2つの端子同士を着脱可能且つ強い密着力で接続する。【解決手段】接続用アダプタ10は、流動食を流出可能な流出用端子20と流入用端子42との間を接続する。この接続用アダプタ10は、筒体60と、筒体60内で該筒体60の軸方向に沿って貫通形成される貫通孔62とを含む。筒体60は、流出用端子20に密着して保持される上流側装着部70と、流入用端子42に密着して保持される下流側装着部72とを有し、各装着部70、72のデュロメータ硬さが60~90の範囲内に設定されている。【選択図】図1
