PROBLEM TO BE SOLVED: To provide a rubber button in which the cleaning (disinfection) operation of a surface of a rubber material is facilitated, and the number of parts is reduced to reduce the production cost and simplify the management of thereof.SOLUTION: The rubber button is connected with a blood circuit, and has the rubber material 1 formed with a slit 1a, and a connecting line 3 can be connected thereto, the connecting line having a connector 4 insertable to the slit 1a of the rubber material 1, formed at a distal end thereof, and the connecting line capable of sampling a fluid that flows in the blood circuit by inserting the connector 4 to the slit 1a or capable of injecting another fluid into the blood circuit. The rubber button includes a connection 2a and 2b that can be optionally switched between an occluded state where an upper part of the rubber material 1 is covered cylindrically and an open state where the upper part of rubber material 1 is opened, and can latch and hold the connector 4 inserted to the slit 1a in the occluded state.COPYRIGHT: (C)2013,JPO&INPIT【課題】ゴム材の表面の清掃(消毒)作業を容易に行わせることができるとともに、部品点数を削減して製造コストの低減及び管理の容易化を図ることができるゴムボタンを提供する。【解決手段】血液回路に接続され、スリット1aが形成されたゴム材1を有するとともに、ゴム材1のスリット1aに挿通可能なコネクタ4が先端に形成されて当該コネクタ4をスリット1aに挿通させて血液回路を流れる流体を採取或いは別個の流体を当該血液回路に注入し得る接続ライン3を接続可能とされたゴムボタンにおいて、ゴム材1の上部を筒状に覆った閉塞状態と当該ゴム材1の上部を開放した開放状態とで任意切り換え可能とされるとともに、当該閉塞状態でスリット1aに挿通したコネクタ4を係止して抜け止め可能とされた接続部2a、2bを具備したものである。【選択図】図14
