  • 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.

  • Publication number: 20190070400
    Abstract: A one-piece medical connector has a unitary body. The unitary body includes a rigid portion that forms a housing. The unitary body also includes a resilient portion located at least partially within the housing. At least a movable portion of the resilient portion is configured to move relative to the rigid portion. Movement of the resilient portion selectively permits fluid flow through the connector. The rigid portion and the resilient portion form a one-piece unitary connector.

  • 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.

  • Publication number: 20180185627
    Abstract: A medical valve has a housing with an inlet housing and an outlet housing. The interior of the inlet housing and/or the outlet housing has a contact surface. A resilient element sits within the housing and is configured to control fluid flow through the inlet. The resilient element has a proximal portion with a normally closed aperture configured to open when actuated by a medical device. The resilient element also has a distal portion adjacent to the outlet, and a central portion between the proximal portion and the distal portion. The central portion has a wall that defines a fluid chamber in the open mode and in the closed mode. The wall has at least one projection extending radially outward. The projection is configured to maintain compressive contact with the contact surface of the housing and to apply an inwardly compressive force on the resilient element, increasing the wall stiffness.
