PROBLEM TO BE SOLVED: To provide a blood circuit panel capable of preventing a connecting tube from kinking or projecting from a mounting groove, and from coming into contact with components of respective types of devices and of a blood circuit, by cushioning extention and projection due to pulsation and rotation of a pump.SOLUTION: The blood circuit panel includes at least a mounting groove BTM for a blood circuit tube BT, and a mounting groove JTM of a connection tube JT for connecting the blood circuit tube BT and a pump tube PT. Further, the blood circuit panel includes a mounting groove JTLM for a loop part JTL of the connection tube JT halfway trough the mounting groove JTM. The mounting groove JTLM has such a shape as to have a space to which at least the loop part JTL of the connection tube JT can be loosely fitted.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】ポンプの拍動、回転による接続チューブの伸びやせり出しを緩衝できるため、接続チューブのキンク、装着溝から外へはみ出して各種装置の構成部品や血液回路の構成部品の接触を防止できる血液回路パネルを提供すること。【解決手段】少なくとも血液回路チューブBTの装着溝BTMと、血液回路チューブBTとポンプチューブPTとを繋ぐ接続チューブJTの装着溝JTMを有する。当該装着溝JTMの途中に、接続チューブJTのループ部JTLの装着溝JTLMを形成した。当該装着溝JTLMは少なくとも接続チューブJTのループ部JTLが遊着できる空間を有する形状である。【選択図】図1
