1. An access port device comprising:
- a catheter hub comprising a hub body, a catheter tube having a tube opening extending from the hub body, a flow chamber defined by the hub body comprising a flow opening terminating at an exterior surface of the hub body, and a needle port having an opening terminating at the exterior surface of the hub body, which is spaced apart from the flow opening;
a needle hub having internal threads formed in the needle hub, the needle hub comprising a needle having a needle tip extending through the opening of the needle port and the catheter tube but not the flow opening of the flow chamber; and
a housing disposed between the needle hub and the catheter hub;
the housing being removably engaged to the catheter hub and the needle hub;
the housing having external threads threadedly engaged to the internal threads of the needle hub; and
wherein the tube opening is at an angle to the flow opening of the flow chamber and the needle is mounted off-center relative to the needle hub;
wherein when the needle hub is rotated relative to the housing and the catheter hub, the housing remains fixed to the catheter hub and the needle hub moves a control distance relative to the catheter hub to create a flow path for blood flashback.

Abstract
A venous access device is generally discussed herein with particular discussions extended to port access device having a protective clip. The port access device includes a needle hub having a needle extending therefrom and a catheter hub having a catheter tube extending therefrom with the needle positioned inside the tube in a ready to use position. A tip protector is positioned inside a clip housing, which is positioned in between the catheter hub and the needle hub.

13. An access port device comprising:
-
a catheter hub comprising a catheter tube extending therefrom and a flow port, a needle hub having internal threads formed in the needle hub, the needle hub comprising a needle having a needle tip extending through the catheter tube and beyond a distal end of the catheter tube, a housing disposed between the needle hub and the catheter hub comprising an axial opening having the needle passing therethrough, the housing having external threads, and a tip protector for covering the needle tip when the needle is retracted away from the catheter tube positioned inside a cavity defined by the housing; and wherein the external threads of the housing threadedly engage with the internal threads formed in the needle hub; and wherein the needle hub is rotatable relative to the housing to disengage the needle hub a controlled distance relative to the catheter hub to create a flow path for blood flashback and the housing remains removably fixed to the catheter hub during rotation of the needle hub relative to the housing. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. An access port device comprising:
-
a catheter hub comprising a needle port having a needle inlet opening, a catheter tube, and a flow chamber having a flow inlet opening spaced from the needle inlet opening formed in the catheter hub for fluid flow through the catheter hub in fluid communication with the catheter tube; a needle hub comprising a needle having a needle tip extending through the needle inlet opening of the needle port and the catheter tube and beyond a distal opening of the catheter tube, a housing disposed between the needle hub and the catheter hub and removably coupled to both the needle hub and the catheter hub, and a tip protector for covering the needle tip when the needle is removed from the catheter tube located inside the housing; and wherein a fluid path defined by the catheter tube is orthogonal to a fluid path defined by the flow chamber; wherein the needle hub is threadedly engaged with the housing; wherein the housing is configured to lock from rotating against the catheter hub, when the needle hub moves a control distance relative to the catheter hub to create a flow path for blood flashback during rotation of the needle hub with respect to the housing. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
