Abstract

In a fluid conduit connecting device for medical purposes a housing and a connecting member, being connectable to the housing, carry cooperating sealing surfaces. For the purpose of protecting the sealing surfaces of the connecting member these surfaces are covered by protective surfaces of a protective member prior to the connection of the connecting member to the housing. Protective member is arranged to uncover the sealing surfaces when the connection into the housing takes place. The device is suitable particularly for connecting the blood stream of a patient to an external conduit and allows continuous arteriovenous hemofiltration.
