Hemostatic connector

A hemostatic connector comprising:

• an insertion hole configured such that an introduction member that is introduced into a human body is inserted through the insertion hole;
• a hemostatic member configured to block a gap between a peripheral surface of the insertion hole and the introduction member;
• a connector main body part in which the hemostatic member is provided, the connector main body part configuring a first passage that is a portion of the insertion hole;
• a coupling pipe part configured to be coupled to a hub of a sheath introducer, the coupling pipe part configuring a second passage that is a portion of the insertion hole different to the first passage;
• and
• a housing cylindrical part internally housing the hub coupled to the coupling pipe part,
• wherein:
• the coupling pipe part is configured to be inserted into an internal hole of the hub from a base end side of the hub, the coupling pipe part being configured to be coupled to the hub in a state in which the coupling pipe part penetrates a hemostatic valve provided in the internal hole when the coupling pipe part is inserted into the internal hole,
• the connector main body part and the coupling pipe part are configured to be inseparable,
• a branch pipe passage is formed in the housing cylindrical part such that a branch pipe part that protrudes from an outer peripheral surface of the hub is caused to be passed through the branch pipe passage when coupling the coupling pipe part to the hub,
• a portion of the branch pipe passage is an engagement passage part that extends in a peripheral direction of the housing cylindrical part, the engagement passage part being configured to engage with the branch pipe part by the branch pipe part of the hub coupled to the coupling pipe part being inserted into the engagement passage part,
• an urging member is provided in an interior of the housing cylindrical part, the urging member urging the hub toward a leading end side in a state in which the branch pipe part is engaged with the engagement passage part, the leading end side being an opposite side of the base end side,
• a facing member is provided in the interior of the housing cylindrical part, the facing member facing a base end surface of the hub housed in the housing cylindrical part,
• the facing member includes a hole configured such that the coupling pipe part is inserted through the hole, the facing member being configured to move along the coupling pipe part inserted through the hole,
• the urging member is provided on the base end side of the facing member, the urging member urging the hub to the leading end side via the facing member,
• the facing member includes an elastic seal part configuring at least a part of the hole,
• an inner peripheral surface of a portion of the hole configured by the elastic seal part is in close contact with an outer peripheral surface of the coupling pipe part inserted through the hole,
• the facing member includes a facing plate part that is provided facing the base end surface of the hub, and the elastic seal part that is plate-shaped and is provided on the base end surface side of the facing plate part, and
• the elastic seal part is disposed in a state of being pressed against the facing plate part due to an urging force of the urging member.
