  • Patent number: 10857345
    Abstract: A medical connector assembly for establishing a fluid connection between a first medical device and a second medical device includes a multi-use connector and a plurality of single-use connectors connected in series. The multi-use connector has a proximal end opposite a distal end along a longitudinal length thereof. The plurality of single-use connectors each have a proximal end opposite a distal end along a longitudinal length thereof. The distal end of the multi-use connector is releasably connected to the proximal end of a first of the serially-connected single-use connectors. When a second of the serially-connected single-use connectors is disconnected from the first single-use connector, the first single-use connector remains connected to the multi-use medical connector as a sterility retaining cover.
