Abstract:
A catheter and introducer needle assembly, comprising;a catheter having a proximal end and a distal end;a catheter hub connected to the proximal end of the catheter and in fluid communication with the catheter, the catheter hub having a proximal wall defining a proximal opening and a distal wall defining a distal opening;a valve body having a distal face and a proximal face disposed in the catheter hub for rotary movement therein, the valve body defining a longitudinally extending passage therethrough which may be aligned with the proximal opening and the distal opening in a particular rotary orientation;a rotary biasing mechanism disposed in the catheter hub and in contact with the valve body;an introducer needle having a proximal end and a distal end disposed inside the catheter and the catheter hub through the passage and the proximal opening and the distal opening;a needle hub having a proximal end and a distal end connected to the proximal end of the needle; anda first tab radially extending from the valve body and a second tab located in the catheter hub to prevent over rotation of the valve body with respect to the catheter hub under the force of the rotary biasing mechanism.
