Abstract

A medical connector that allows ventilation of vapor used in vapor sterilization and has an internal flow route that is tightly closable without using any separate clamping device. A medical connector includes a body having an internal flow route connected to an other flow route, proximal portions included in the body and having respective one-side connection ports at which the internal flow route is connectable to the one flow route, a distal portion having an other-side connection port at which the internal flow route is connectable to the other flow route, one-side lid portion, and an other-side lid portion whose state is switchable between a closing state and a ventilating state in which the other-side lid portion covers the other-side connection port such that ventilation is allowed.

Claims17

Dependent claims

A medical connector to be provided between and connectable to one flow route and an other flow route through which liquid is allowed to flow, the medical connector comprising:

a body having an internal flow route through which the liquid flowing in the one flow route is allowed to flow into the other flow route;
a proximal portion included in the body and having a one-side connection port at which the internal flow route is connectable to the one flow route;
a distal portion included in the body and having an other-side connection port at which the internal flow route is connectable to the other flow route;
a plurality of lids, at least one of the plurality of lids comprising:
a one-side lid portion with which the one-side connection port is closable;
and
at least one of the plurality of lids comprising:
an other-side lid portion whose state is switchable between a closing state in which a first side of the other-side lid portion is in direct contact with and closes the other-side connection port such that the internal flow route is tightly closed and a ventilating state in which a second side of the other-side lid portion is in direct contact with and covers the other-side connection port such that ventilation is allowed through the second side of the other-side lid portion.
