Abstract
Catheter assemblies are described having a catheter hub with a catheter tube and a needle hub with a needle projecting through the catheter tube. The catheter hub has a valve or a septum for stopping or slowing down the flow of fluid in or out of the catheter hub when the valve or septum is closed. The valve or septum has an exposed proximal wall that enables the valve to be wiped or cleaned with an antiseptic solution. The valve further has a cavity for receiving at least part of a needle guard, which is incorporated for preventing accidental needle stick with the needle tip.
Claims24
A safety IV catheter comprising:
- a catheter hub attached to a catheter tube,
- a valve attached to the catheter hub, said valve comprising an interior cavity, a proximal end wall exposed externally of the catheter hub, and a slit;
- a needle hub attached to a needle and the needle extending through the catheter tube;
- a tip protector comprising a distal end portion, a proximal wall comprising an opening, and a small profile located between the distal end portion and the proximal wall;
- and
- wherein the distal end portion of the tip protector is located inside the interior cavity of the valve and the proximal wall located externally of the valve.
A method for manufacturing a safety IV catheter comprising:
- forming a catheter hub and attaching the catheter hub to a catheter tube,
- attaching a valve to the catheter hub, said valve comprising an interior cavity, a proximal end wall exposed externally of the catheter hub, and a slit;
- forming needle hub and attaching the needle hub to a needle and the needle extending through the catheter tube;
- placing a tip protector, at least in part, inside the interior cavity of the valve, said tip protector comprising a distal end portion, a proximal wall comprising an opening, and a small profile located between the distal end portion and the proximal wall.
A method for manufacturing a safety IV catheter comprising:
- forming a catheter hub and attaching the catheter hub to a catheter tube,
- attaching a valve to the catheter hub, said valve comprising an interior cavity, a proximal end wall, and a slit;
- forming needle hub and attaching the needle hub to a needle and the needle extending through the catheter tube;
- placing a tool over the needle and at least partially through the slit;
- said tool comprising a hollow interior;
- and
- placing a tip protector, at least in part, inside the interior cavity of the valve, by sliding the tip protector at least partially through the hollow interior of the tool.
A safety IV catheter comprising:
- a catheter hub attached to a catheter tube,
- a valve attached to the catheter hub, said valve comprising an interior cavity, a proximal end wall located at a proximal end of the catheter hub, and a slit;
- a needle hub attached to a needle and the needle extending through the catheter tube;
- a tip protector comprising a distal end portion of a first dimension, a proximal wall of a second dimension comprising an opening having an opening dimension, and a center section of a third dimension located between the distal end portion and the proximal wall, the first dimension being larger than the second and the third dimensions and the third dimension is smaller than both the first and the second dimension;
- and
- wherein the distal end portion of the tip protector is located inside the interior cavity of the valve and the proximal wall located externally of the valve.
A safety IV catheter substantially as shown in the figure and described in the specification.
