Patent attributes
A connector system for sterile connection includes a male type patient side connector having a tube connecting portion at a rear end portion thereof, a protective cap for the patient side connector, an inner cap held in the protective cap and including a ring-shaped portion that supports a disinfectant-impregnated member therein, and a female type circuit side connector including an outer cylinder and an inner cylinder fixed at one end of the outer cylinder, where the inner cylinder includes an internal end portion located inside the outer cylinder and an external end portion exposed outside the outer cylinder. When the protective cap is fitted with the patient side connector, the disinfectant-impregnated member contacts with the patient side connector. When the protective cap is removed therefrom, the inner cap becomes retained in the patient side connector. When such a patient side connector is connected with the circuit side connector, the internal end portion of the inner cylinder penetrates through the disinfectant-impregnated member and a septum. When the connection is released, the inner cap is detached from the patient side connector.
