Image Number 2 for United States Patent #5487728.
The connector assembly includes a female luer connector having a hollow needle disposed in recessed position within a rigid tubular portion. A rubber shield having a tubular portion and a septum at one end is positioned over the needle to maintain the needle in a sealed condition. A compression ring is disposed about the rubber septum to hold the septum in compression whereby the punctured area can be punctured many times without leaking when subjected to relatively high pressures. The male connector may be of any suitable type for pushing the rubber septum into the female connector for piercing by the needle of the female connector.
