PROBLEM TO BE SOLVED: To provide a sampling port which is so simple in structure that it can be inexpensively manufactured, which can be easily assembled, and which can prevent the proliferation of bacterium.SOLUTION: The sampling port comprises: a body 2 having a liquid passage 3 communicating with a dialysate solution transportation tube a recess portion 5 formed in a communication shape on the upper side of the liquid passage 3 in the body 2 a recess 6 formed on the upper side of the recess portion 5 a plug body 7 fitted in the recess portion 5 and having such a rubbery elasticity as can insert and remove an injection needle a main cap 11 detachably mounted on the upper portion of the body 2 and having such a downward tapered inner cylinder portion 12 at its center as enters the recess 6 of the body 2 and a plug cap 13 fitted attachably/detachably in the cylinder portion 12 of the main cap 11. At the lower end of the plug body 7, there is formed a half-crescent portion 7a along the side portion of the plug body 7 on the inner circumference of the liquid passage 3.COPYRIGHT: (C)2014,JPO&INPIT【課題】 構造が簡単で安価に製造できると共に容易に組立て可能であり、しかも細菌の繁殖が防止できるようにする。【解決手段】 透析液輸送チューブと連通する液流路3を有する本体2と、本体2における液流路3の上側に連通状に形成された凹陥部5と、凹陥部5の上側に形成された凹部6と、凹陥部5内に嵌め込まれ、注射針が挿脱自在なゴム状弾性を有する栓体7と、本体2の上部に着脱自在に装着され、中央には本体2の凹部6内に入る下向きテーパー状の内筒部12が設けられた主キャップ11と、主キャップ11の内筒部12に装着自在に嵌め入れられる栓キャップ13とを備えており、栓体7の下端には液流路3の内周面における栓体7側部分に沿う凹弧部7aが形成されている。【選択図】 図1
