ABSTRACT:
An elastomeric member for occluding a medical terminal such as a junction terminal to provide a seal and penetratable to establish fluid connection by a blunt needle or cannula in which improved security against passage of contamination is provided. The needle or cannula preferably passes through a perforated passage. The passage can have at least two portions, one having a slit for normally sealing tightly in the absence of a cannula or needle and the other having a bore communicating with the slit and closely conforming to the cannula surface. Other sealing arrangements are detailed.
