Abstract
An intravascular blood extraction system for phlebotomy through a previously placed peripheral intravascular catheter having a cannula within a protective housing and/or structures and/or structure, a cannula forming a laminar fluid path extending from the distal fluid entry to a lateral or proximal fluid exit orifices directly coupled to the protective housing and/or structures and/or structure, a slider o plunger actuator coupled to the fluid exit orifice of the cannula so that distal advancement of the slider advances the cannula inside a fluid vessel.
Claims41
A blood extraction device comprising:
- a housing having a proximal end and a distal end;
- a blood collection orifice in a blood collection port formed in a wall of the housing;
- a coupler disposed on the distal end of the housing, the coupler adapted and configured for engagement with a catheter or a peripheral vascular device;
- a slider accessible from outside of the housing and moveable in relation to the housing proximal end and the housing distal end;
- and
- a cannula having a proximal end and a distal end and a cannula lumen extending from a distal opening to a proximal opening, the cannula is within the housing and coupled to the slider wherein the cannula distal end is moveable beyond the coupler by axial movement of the slider, wherein the blood extraction device is in a first position when the cannula is inside of the housing and there is not a fluid pathway between the distal opening of the cannula and the blood collection orifice and the blood extraction device is in a second position when the cannula distal end is outside of the housing and there is a fluid pathway established between the cannula distal opening and the blood collection orifice.
