  • Patent number: 10376684
    Abstract: A medical port includes a hub having a body forming a hub chamber for containing a fluid, and a proximal opening to the hub chamber for receiving a medical implement. The port also has a valve member, a first radial fluid channel, and a second radial fluid channel. The valve member is located within the hub chamber, has a radial portion, and closes the proximal opening when the medical port is in a closed mode. The first and second radial fluid channels are in fluid communication with the hub chamber when the medical port is in the closed mode. The radial portion of the valve member restricts fluid communication between the first radial fluid channel and the hub chamber when the medical port is in an open mode.

  • Patent number: 10368789
    Abstract: A medical port has a housing forming an interior with a fluid inlet and a fluid channel extending from the fluid inlet. The housing also has an exterior wall forming at least one radial opening to the interior. In addition to the housing, the medical port also has a resilient valve element within the housing interior configured to control fluid flow through the inlet, and a biasing element movably couplable with the housing. The resilient valve element has a proximate body portion proximate to the radial opening when in the closed mode. The biasing element also has a constraining portion configured to cooperate with the radial opening to contact at least the proximate body portion of the valve element when in the closed mode. The biasing element constraining portion preferably is configured to normally resist radial outward movement of the proximate body portion when in the closed mode.

  • Patent number: 10226613
    Abstract: A multi-purpose covering for use with a medical device having a housing and an access port includes a substrate with a first end and a second end. The substrate defines the structure of the covering. The covering also includes a first securing portion nearer the first end of the substrate for securing at least one protective cap to the substrate, and a second securing portion nearer the second end for securing the substrate to the medical device. To protect the access port when the covering is sealed to the medical device, the covering can also include a sealing portion configured to be releasably secured to the medical device.

  • Patent number: 10123728
    Abstract: A catheter stabilization device includes a medical connector and a docking pod. The medical connector is configured to connect to a medical implement. The docking pod has an internal fluid path, a first opening, and an inlet opening. The first opening may be placed in fluid communication with a catheter. A docking pod adhesive layer that is located at least partially beneath at least a portion of the docking pod secures the docking pod to a patient. The device also includes an adherent substrate with a first film layer and at least a second film layer. The first and second film layers at least partially define a fluid pathway that extends through the adherent substrate and fluidly connects the medical connector and the inlet opening of the docking pod.

  • Patent number: 10039484
    Abstract: A device for stabilizing a patient catheter includes a docking pod with a body, an inlet, an outlet, an internal fluid path between the inlet and the outlet, and a securement surface located on an underside of the docking pod. A docking pod adhesive layer located at least partially on the securement surface of the docking pod may secure the docking pod to the patient such that the securement surface and the docking pod adhesive layer form a generally planar or concave surface when secured to the patient. A valve mechanism located within the internal fluid path of the docking pod may control fluid flow through the docking pod. The device may also have a luer connector that is fluidly connected to the outlet of the docking pod and configured to be connected to the catheter.

  • Patent number: 9872644
    Abstract: A sampling port includes a hub having a body that forms a hub chamber for containing a fluid. The hub also has a proximal opening to the hub chamber for receiving a medical implement, and the hub chamber has a valve member that normally closes the opening. The valve member has a valve wall forming a valve interior. The sampling port also has a first and second fluid channel formed by the hub body and in fluid communication with the hub chamber. The first and second channels have radial portions and proximally extending portions with proximally extending longitudinal axes. The proximally extending longitudinal axes form a plane therebetween that diverges from the longitudinal axis of the first fluid channel.

  • Patent number: 9849274
    Abstract: A medical valve transitions between an open mode that permits fluid flow, and a closed mode that prevents fluid flow. To that end, the medical valve has a housing with an inlet and an outlet, a rigid member movably mounted within the housing, and a resilient member with a sealing portion. The housing also has at least one relief zone that is in fluid communication with the outlet when the valve is in the closed mode. The rigid member may have a proximal end, a distal end, and a flow channel. The relief zone may be radially outward from the sealing portion. The sealing portion may seal the valve and prevent fluid from passing through the valve when in the closed mode.

  • Patent number: 9604047
    Abstract: A gland member within a medical valve is configured to have a substantially consistent or enlarging internal volume as the valve transitions from a closed mode to an open mode. The valve has a housing forming an interior containing a flow path, and a stationary post member within the interior. The post member has a lumen that is a part of the flow path. The lumen has an opening to the interior of the housing. The valve further includes a gland member circumscribing the post member to produce a variable volume region formed at least in part between the gland member itself and the post member. The variable volume region is a part of the flow path, while the gland member occludes the post lumen opening when in the closed mode. The variable volume region has an open volume that is no less than its closed volume.

  • Patent number: 9138572
    Abstract: A medical valve has an open mode that permits fluid flow, and a closed mode that prevents fluid flow. To that end, the medical valve has a housing having an inlet and an outlet, and a resilient member within the housing. The resilient member has a body portion with a free state when undeformed by external mechanical forces and a deformed state when the valve is in the closed mode. The body portion is formed to return toward the free state as the valve transitions from the closed mode to the open mode and defining at least part of a fluid path through the valve.

  • Patent number: 8968261
    Abstract: A medical valve has an open mode that permits fluid flow, and a closed mode that prevents fluid flow. To that end, the medical valve has a housing with an inlet portion and an outlet portion, a rotating member having a protruding member, and a resilient member with a complimentary surface that mates with the protruding member. The inlet portion and outlet portion of the housing compress the protruding member into the resilient member to bias the valve to the closed mode.

  • Patent number: 8876784
    Abstract: A medical valve includes a housing having an interior forming an inlet and an outlet. A longitudinally movable member is secured within the interior of the housing. External to the movable member and within the interior is a fluid path. Movement of the movable member controls fluid flow between the inlet and the outlet via the fluid path. The outlet produces no greater than a negligible drawback or positive push during withdrawal of a nozzle.
