  • Patent number: 10940306
    Abstract: A connector for transferring fluid and method therefor. The connector may have a first port and a second port which may be coupled together at a main channel with a valve element therein controlling fluid flow through the first port. The first port joins the main channel to provide a fluid path around the valve element and through the second port.
    Type: Grant

  • Patent number: 10842984
    Abstract: A connector for transferring fluid, the connector may have a first port, a second port, and a third port which may be fluidly coupled together at an internal chamber with a first valve element therein controlling fluid flow through the second port. The connector can have ribs extending along the connector to provide a fluid path around the valve element and between the first port and the second port. The valve element can separate the internal chamber into an air chamber and a liquid chamber, and the third port can be continuously coupled to the liquid chamber regardless of a position of the valve element.

  • Patent number: 7600530
    Abstract: A connector comprising a needless access device and a backflow check valve for transferring fluids and method therefor. The connector may have a first port, a second port, and a third port. A first valve element may be positioned within the first port and a second valve element may be positioned within the second port. The first valve element may be in a first position as a first fluid flows between the first and third ports. The second port may be used to introduce a second fluid into the connector. Upon introduction of the second fluid to the connector, the first valve element may move from the first position to a second position. In the second position, fluid may be prevented from flowing past the first valve element.
