  • Patent number: 10195411
    Abstract: A tubing set includes a rigid medical fluid chamber, medical fluid tubing, and a cuff. The rigid medical fluid chamber includes a housing and a tubular fitting extending from the housing. The medical fluid tubing is connected to the tubular fitting such that the medical fluid tubing is in fluid communication with the medical fluid chamber. The cuff is positioned over a length of the medical fluid tubing to inhibit denting of a wall of a length of the medical fluid tubing connected to the tubular fitting and extending beyond the tubular fitting. The cuff inhibits denting when the medical fluid tubing is coiled.

  • Patent number: 8545449
    Abstract: The invention provides a multi-port fluid access device for medical use, such as in a blood-flow circuit during dialysis. The device has a main tubular body and a needle access port and a needleless access port located at positions axially offset from each other. Each port has a tubular body with a septum sealing the passageway to the main fluid channel of the main tubular body. Alongside the main tubular body are members providing finger-gripping surfaces at or near the axial position of the needle access port. There is also a needle shield located between the finger gripping surfaces and the needle access port. Use of the device permits either or both of needle access and needleless access to a patient's blood during dialysis.
