Abstract
A new catheter stick protector is described having a metal flap clip which snaps down into place to prevent return of the needle through the protector device once withdrawn. The device is small and received over the needle to provide an interface between the needle hub and the hub of a catheter like product. A sleeve of hydrophobic or fluid impermeable material is provided and attached at one end to the needle hub and at a second end to the tip protector. The length of the material is selected to hold the tip protector in a position just extending beyond the tip of the needle of a catheter inserter.
Claims22
A catheter introducer assembly comprising:
- A) a needle having a tip at a distal end thereof;
- B) a hub attached at a proximal end of said needle;
- C) a tip protector slidable along said needle said tip protector comprising:
- 1) means attaching said tip protector directly to said hub to limit movement of said tip protector beyond said tip said means for attaching being sufficiently flexible to permit compact storage;
- 2) holding means including a movable obstruction for obstructing the needle to for preventing movement of said tip protector toward said hub once said tip protector has been moved to a position covering said tip.
In a catheter introducer product of the type having a tubular catheter having a hub at a proximal end thereof and an introducer needle received within the tubular catheter for introduction of the catheter into a patient;
- said introducer needle being in fluid communication with a needle hub comprising a flash chamber and further including anti-stick protection means which is slidable from a first position proximal said needle hub to a second position covering said needle tip;
- the improvement wherein said tip protector includes a substantially cylindrical clip having a flap formed in one surface thereof, said flap being plastically deformed inward into the inner space of said cylindrical clip.
A catheter introducer assembly having a needle, a needle tip at a distal end of said needle, a hub at a proximal end of said needle and a tubular catheter received over said needle, a protective element comprising;
- a) a tip cover slidable along said needle and defining a passage for receiving said needle;
- b) a flexible tubular restraint which receives said needle therein and extends between said tip cover at a distal end and a point adjacent said hub at a proximal end to restrain movement of said tip cover beyond and/off said needle tip;
- and
- c) a movable lock within said tip cover that moves from a first position adjacent said needle to a second position between said needle tip and said passage.
