Abstract:
(EN) Provided is a novel indwelling needle provided with a hemostatic valve that is capable of discharging air in an internal flow path. An indwelling needle 10 provided with a hemostatic valve, the indwelling needle 10 having a cannula 12 to be inserted percutaneously into a blood vessel on the distal end side thereof and being equipped with a connecting connector 14 on the proximal end side, an internal flow path 18 being formed from the cannula 12 to the connecting connector 14, and a hemostatic valve 16 being disposed inside the connecting connector 14, wherein an air vent passage 118 that allows the internal flow path 18 to communicate with an outside space is formed in the connecting connector 14 on the cannula 12 side from the hemostatic valve 16, and a filter 120 that allows gas to pass but does not allow liquid to pass through is mounted in a compressed state in the air vent passage 118.
(FR) La présente invention concerne une nouvelle aiguille à demeure munie d’une valve hémostatique qui permet d'évacuer l’air d'un circuit d’écoulement interne. L'aiguille à demeure (10) munie d’une valve hémostatique selon l'invention présente une canule (12) à insérer de manière percutanée dans un vaisseau sanguin sur son côté d’extrémité distale et qui est munie d’un raccord de raccordement (14) sur le côté d’extrémité proximale, un circuit d’écoulement interne (18) étant formé de la canule (12) au raccord de raccordement (14), et une valve hémostatique (16) étant disposée à l’intérieur du raccord de raccordement (14). Un passage de ventilation d’air (118) qui permet au circuit d’écoulement interne (18) de communiquer avec un espace extérieur est formé dans le raccord de raccordement (14) sur le côté de la canule (12) depuis la valve hémostatique (16), et un filtre (120) apte à être traversé par le gaz mais pas par le liquide est monté dans un état comprimé dans le passage de ventilation d’air (118).
(JA) 内部流路中の空気を排出することができる、新規な構造の止血弁付留置針を提供する。 経皮的に血管に挿し入れられるカニューラ12を先端側に有していると共に、接続コネクタ14を基端側に備えており、該カニューラ12から該接続コネクタ14に至る内部流路18が形成されていると共に、該接続コネクタ14の内部に止血弁16が配されている止血弁付留置針10において、前記接続コネクタ14には前記内部流路18を前記止血弁16よりも前記カニューラ12側において外部空間へ連通させるエア抜き通路118が形成されており、該エア抜き通路118上に、気体は通過させるが液体は通過させないフィルタ120が圧縮された状態で装着されている。
