  • Patent number: 11406811
    Abstract: A needleless injection port assembly includes first and second body parts and a resilient barrier received within the body. A cannula attached to the first body part is received within an internal cavity of the resilient barrier. The resilient barrier is moveable between a less axially compressed first position in which fluid flow through the injection port assembly is prevented and a more axially compressed second position in which fluid flow through the assembly is allowed. An interference fit is provided between the resilient barrier and the cannula to seal against fluid flow through the cannula when the resilient barrier is in the first position. The cannula has an internal fluid passageway with a non-circular cross section providing increased fluid flow.

  • Patent number: 10786664
    Abstract: An injection port assembly including a body having first and second mating structures configured to mate with a first connector for a first fluid pathway and a second connector on a device, respectively. A resilient barrier substantially contained within the body and compressible from a first position in which fluid flow between the first and second connectors is blocked to a more compressed second position in which fluid flow between the first and second connectors is permitted. A hollow cannula can be coupled with the first mating structure and disposed within the resilient barrier, the hollow cannula having a distal end configured to extend through the resilient barrier when the resilient barrier is in the second position, the distal end having lateral slots. The resilient barrier can have first and second annular sealing rings positioned above and below the lateral slots respectively.

  • Patent number: 10449575
    Abstract: A single piece device enables medical clinicians to clean and disinfect both an injection port (needleless I.V. connector) and a vascular access catheter hub. The device has a body with a first end having a blind hole with a wall adapted to be engageable with the threads on the housing of an IV connector and a bottom surface adapted to engage the top surface of the IV connector. The device body has a second end defining a male-luer slip extending out of a recess. The male-luer slip is adapted to extend into a standard vascular access catheter hub such that it engages the inner walls of the catheter hub, and the recess is adapted to receive and be engageable with the outside thread element of the catheter hub.

  • Publication number: 20190134303
    Abstract: An injection port assembly comprises a body having a first mating structure and a second mating structure coupled together. A resilient barrier is received within the body and compressible between a less compressed first position in which fluid flow through the injection port assembly is blocked, to a more compressed second position in which fluid flow through the injection port assembly is permitted. A hollow cannula is coupled to the first mating structure and configured to be received within the resilient barrier. The hollow cannula has a distal end portion configured to extend through the resilient barrier when the resilient barrier is in the more compressed second position. The hollow cannula is opaque and both the second mating structure and the resilient barrier are transparent, so that any fluid leakage into the internal cavity of the resilient barrier is visible through the resilient barrier and the second mating structure against an opaque background provided by the opaque cannula.
