Abstract
Description
Claims (2)
- 医療用容器の口部に取り付けられ、医療用容器内を外部に対して密閉するとともに、外部からノズルが挿入されることにより医療用容器内とノズルとを連通可能にする医療用栓体であって、
医療用容器の口部を封鎖するための封鎖体と、
前記封鎖体を覆うように設けられたベース部と、
ノズルによって押し込み可能に設けられ、中空管路を含む針部とを備え、
前記ベース部は、前記封鎖体に向けてノズルを挿し込み可能な筒状部と、前記封鎖体の位置する側とは反対側に位置する前記筒状部の一端部側に設けられ、ノズルの挿抜に応じて開閉するように設けられたスリット状の弁孔を有する弁部とを含み、
前記針部は、ノズルに押し込まれることにより、前記封鎖体を刺通して前記中空管路を介して医療用容器内とノズルとが連通するように前記封鎖体、前記筒状部および前記弁部によって囲まれた収容空間に収容され、
前記弁部は、前記針部が前記封鎖体を刺通して前記中空管路を介して医療用容器内とノズルとが連通した状態において、ノズルの外周面に当接することにより前記収容空間が外部に対して密閉された状態を維持するとともに、前記針部が前記封鎖体を刺通した後にノズルが前記筒状部から引き抜かれた状態において、前記筒状部の前記一端部を閉鎖することにより前記収容空間が外部に対して密閉された状態を維持するように設けられている、医療用栓体。 - 前記封鎖体は、前記ベース部が位置する側に前記筒状部を収容するための凹部を有し、
前記筒状部が前記凹部に収容されている、請求項1に記載の医療用栓体。
