Claim:
A connector system for sterile connection comprising: a male type connector including a tube connecting portion at a rear end portion thereof; a protective cap having a substantially cylindrical shape with a closed first end and being capable of connecting and disconnecting with/from a front end side of the patient side connector; an inner cap including a ring-shaped portion that supports a disinfectant-impregnated member therein, the inner cap being retained inside the protective cap in an initial state; and a female type connector having a double-cylinder structure in which an inner cylinder is fixed at one end portion of an outer cylinder, the inner cylinder including an internal end portion located inside the outer cylinder and an external end portion exposed outside the outer cylinder and capable of connecting with a tube, wherein a channel for solution is connected by fitting the outer cylinder of the female type connector with the male type connector, when the protective cap is fitted with the male type connector, the inner cap assumes a state of being retained at the front end side of the male type connector, when the protective cap is removed from the male type connector, the inner cap is detached from the protective cap because of a retaining force at the front end side of the male type connector, when the patient side connector with the inner cap retained at the front end thereof is connected with the female type connector, the internal end portion of the inner cylinder penetrates through the disinfectant-impregnated member in the inner cap, so that the channel is opened, and when the connection between the male type connector and the female type connector is released, the inner cap is retained inside the female type connector and is detached from the front end of the male type connector.
