Abstract

A tip shield of a catheter assembly has a resilient clip compartment, which may become blood-filled during use of the catheter assembly. The resilient clip inside the compartment is released upon withdrawal of the needle of the catheter assembly to disengage the catheter hub from the tip shield. The resilient clip also prevents re-exposure of the needle after being withdrawn into the tip shield. The blood-filled compartment may potentially leak or splash through an opening from the compartment when the resilient clip is released. A covering blocks the opening from the tip shield to minimize the risk of blood exposure. In addition, the covering minimizes the risk of premature release of the resilient clip and re-exposure of the needle.
