PROBLEM TO BE SOLVED: To provide a needleless port improving stable injection and sampling of liquid.SOLUTION: The needleless port includes: a substantially cylindrical port part 21 having an opening into which a male luer can be inserted, formed at one end, and a male screw 21b formed around an outer peripheral surface and a septum 30 disposed at the other end of the port part 21, and provided with a self-closing type slit 31 that is openable by being pressed down by the male luer inserted via the opening. The outside diameter of the port part 21 is conformed to a standard outside diameter dimension of a female-side connector of a lock type connector regulated by ISO 594-2:1998, and the inside diameter of the port part 21 is larger than the standard inside diameter dimension of the female-side connector of the connector regulated by ISO 594-1:1986.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】液体の注入や採取がより安定的に行なえるニードルレスポートを提供する。【解決手段】ニードルレスポートは、雄ルアーが挿入可能な開口が一端に形成されるとともに、外周面に雄ネジ21bが設けられてなる略円筒状のポート部21と、ポート部21の他端に配置され、上記開口を介して挿入された雄ルアーによって押し下げられることで開放可能な自閉式のスリット31が設けられたセプタム30とを備える。ポート部21の外径は、ISO594-2:1998に規定されるロック式コネクタの雌側コネクタの標準外径寸法に準拠しており、ポート部21の内径は、ISO594-1:1986に規定されるコネクタの雌側コネクタの標準内径寸法よりも大きい。【選択図】図2
