摘要
A novel hemostasis valve-equipped indwelling needle that is capable of discharging air in an internal flow path includes a cannula to be inserted percutaneously into a blood vessel on a distal end side thereof, a link connector on a proximal end side thereof, an internal flow path extending from the cannula to the link connector, and a hemostatic valve disposed inside the link connector. An air vent passage that allows the internal flow path to communicate with an external space is formed in the link connector further on the cannula side than the hemostatic valve, and a filter that allows gas to pass through but does not allow liquid to pass through is mounted in a compressed state on the air vent passage.
