  • Patent number: 11642472
    Abstract: A cannula hub includes a shaft mount segment and a cannula coupling segment. A set of coupling nubbins radially extend from the outer surface of the cannula coupling segment. The coupling nubbins are aligned with one another along a helical cannula coupling pathway on the outer surface and are adapted to be received within a cooperative helical groove on a transfer vessel. The coupling nubbins have a protrusion projection distance that is greater than the depth of the groove. When a sufficient rotational force is applied to the cannula hub, the coupling nubbins score the inside face of the groove which increases the groove depth and enables the coupling nubbins to advance along the groove while forming a tight compression fit of the coupling nubbins within the groove.

  • Patent number: 11565084
    Abstract: A low profile catheter system includes a catheter hub with a stabilization surface that is located on an underside of the catheter hub and stabilizes the catheter hub on a patient. A substantially linear flow path extends from an opening at the distal end of the catheter hub to an inlet located within an intermediate portion of the catheter hub. The flow path allows fluid to flow between the distal end and the intermediate portion. The intermediate portion receives a base connector having a fluid path. The fluid path has a first opening and is fluidly connected to the inlet of the flow path in the catheter hub and a biasing member biases the first opening toward the inlet when the base connector is received by the intermediate portion.

  • Patent number: 11529498
    Abstract: A catheter insertion system includes a housing extending along a longitudinal axis. A needle extends distally from a distal end of the housing. The needle has a longitudinal passage coaxially aligned with the housing. A catheter has a length and is sized and shaped to be advanced from a retracted position within the longitudinal passage of the needle to an extended position with at least a portion of the catheter length extending beyond a distal tip of the needle. The needle is typically configured to be retracted back into the housing after the catheter has been advanced, thus providing an integrated catheter and catheter insertion apparatus. After needle retraction, the housing may be taped to the patient's skin while the needle remains protected within the housing. A luer on the catheter may then be connected to a fluid or other source in an otherwise conventional manner.
