ABSTRACT:
The composite seal is formed of a slit elastomeric septum and a sealing member which serves to seal against a blunt ended cannula passing through the slit septum. The composite seal may be made of one piece construction or of two piece construction. The sealing member may be formed of a separate rubber disc to frictionally grip a cannula in place. Alternatively, the sealing member may be formed by a plastic housing in which the slit septum is mounted. In this latter case, the plastic housing has a reduced bore for gripping of the cannula. No exterior mechanical locking elements are required to secure a cannula to the composite seal structure.
