Snap Fit Sterile Connector

This article relates to snap-fit connectors which must be sterile prior to use and must remain sterile while in use.

Sterile connector 1, shown in the above figure, is made up of a male half 3 and a female half 2. Male half 3 and all but the sleeve 4 of female half 2 are made of a medical grade elastomeric material. Both halves, male 3 and female 2, have a bactericidal adhesive-coated pad 5 disposed over their ends. Pads 5 may be weakened with radially scribed lines to permit easy puncturing. As male half 3 is inserted into female half 2, adhesive coated pads 5 adhere to one another.

Male half 3 is made up of a hollow screw 6 with a knurled head 7 to permit easy incremental turning within tough and extremely flexible (such as latex gum) sleeve 4. A threaded portion 8 of screw 6 mates with a columnar internally threaded screw guide portion 9.

To form a connection, hollow screw 6 in female half 2 is incrementally turned within sleeve 4. This action punctures the two sterile adhesively connected pads 5 and forms a sterile opening between the male and female halves. In the operating environment the tapered tip 10 of screw 6 mates with a tapered hole 11 formed within female half 2.
