Abstract
Needle assemblies 500 are disclosed having a multi-purpose protective cap 5. The needle assemblies 500 can embody catheter assembly 120 having a catheter hub 75 and a catheter tube 76 or a hypodermic needle 15 mounted on a needle hub 35. The multi-purpose cap 5 includes a first section 10 covering the needle 15 and a second section 20 having a base portion 40 for covering a hub, such as needle hub 35 or a catheter hub 75. The first section 10 and the second section 20 are separable from one another along a detachment line 30 and the second section 20 is re-useable as a securement device.
Claims22
A needle assembly comprising:
- a needle having a needle shaft attached to a needle hub, said needle shaft comprising a needle tip;
- and
- a protective cap located over the needle shaft comprising a first section and a second section;
- said first section having a bore having the needle shaft located therein and said second section comprising a base covering at least part of the needle hub;
- and
- a detachment line located between the first section and the second section of the protective cap;
- and
- wherein the detachment line is a weakened section or a seam held together by a joining device and is configured to be separable to separate the first section of the protective cap from the second section of the protective cap.
A needle assembly comprising:
- a catheter hub;
- a catheter tube extending from a distal end of the catheter hub;
- a needle disposed at least in part in the catheter tube;
- a needle hub attached to the needle;
- a needle cap placed over the needle and the catheter tube;
- said needle cap comprising a first section and a second section, said first section comprising an elongated sleeve having a bore and said second section comprising base portion comprising an upper opening and a lower opening and covering at least a part of the catheter hub;
- at least one stabilization element extending laterally of the base portion;
- and
- wherein an engagement element on the catheter hub is sized and shaped to extend through the upper opening of the base portion of the second section of the needle cap after the first section separates from the second section along a detachment line.
A method of stabilizing a puncture site comprising:
- separating a protective cap into a first section and a second section along a detachment line;
- said first section comprising an elongated sleeve having a bore and said second section having a base portion comprising two side walls and a top wall;
- placing the second section over a catheter hub so that the base portion of the second section covers at least part of the catheter hub;
- and
- using adhesive to secure the base portion from inadvertent movement.
