Systems and methods for facilitating instrument delivery through a peripheral intravenous catheter

Abstract

A system for facilitating instrument delivery through a peripheral intravenous catheter may include a catheter adapter having a proximal end, a distal end, and a lumen extending there through. The catheter adapter may include a side port. The system may include an extension tube extending from the side port. The system may include a blood control valve disposed in the lumen of the catheter adapter. The system may include a peripheral intravenous catheter extending distally from the catheter adapter.

1 . A system for facilitating instrument delivery through a peripheral intravenous catheter, comprising:
 a catheter adapter having a proximal end, a distal end, and a lumen extending there through, the catheter adapter having a side port;   an extension tube extending from the side port;   a blood control valve disposed in the lumen of the catheter adapter; and   a peripheral intravenous catheter extending distally from the catheter adapter.   
     
     
         2 . The system of  claim 1 , wherein the blood control valve is disposed proximal to the side port, wherein the blood control valve does not allow air venting. 
     
     
         3 . The system of  claim 1 , wherein the blood control valve is disposed distal to the side port, wherein the blood control valve allows air venting. 
     
     
         4 . The system of  claim 1 , wherein the blood control valve allows air venting. 
     
     
         5 . The system of  claim 4 , further comprising:
 a Y-adapter coupled to a proximal end of the extension tube, the Y-adapter having a first port and a second port;   a needleless connector coupled to the first port; and   a needleless connector coupled to the second port.   
     
     
         6 . The system of  claim 1 , further comprising a cap coupled to the proximal end of the catheter adapter. 
     
     
         7 . The system of  claim 1 , further comprising a needleless connector coupled to the proximal end of the catheter adapter. 
     
     
         8 . The system of  claim 1 , further comprising an extension set, the extension set comprising:
 a distal connector coupled to the proximal end of the catheter adapter, wherein the distal connector comprises a cannula that penetrates the blood control valve in response to the distal connector being coupled to the proximal end of the catheter adapter;
 a proximal connector; and 
 tubing disposed between the distal connector and the proximal connector. 
   
     
     
         9 . The system of  claim 8 , wherein the proximal connector comprises a needleless connector. 
     
     
         10 . The system of  claim 8 , wherein the cannula is blunt and constructed of plastic or steel. 
     
     
         11 . The system of  claim 8 , wherein the cannula comprises a plurality of flushing windows. 
     
     
         12 . The system of  claim 1 , further comprising an extension set coupled to the proximal end of the catheter adapter, the extension set comprising:
 a distal connector coupled to the proximal end of the catheter adapter, wherein the distal connector comprises a male luer;
 a proximal connector; and 
 tubing disposed between the distal connector and the proximal connector. 
   
     
     
         13 . The system of  claim 12 , wherein the proximal connector comprises a needleless connector. 
     
     
         14 . The system of  claim 12 , wherein the lumen of the catheter adapter includes an actuator configured to penetrate the blood control valve in response to the distal connector being coupled to the proximal end of the catheter adapter. 
     
     
         15 . The system of  claim 12 , wherein the actuator comprises an extension of the male luer. 
     
     
         16 . The system of  claim 12 , further comprising an instrument delivery device coupled to the proximal end of the catheter adapter, wherein the instrument delivery device comprises an instrument configured to advance distally through the blood control valve and the peripheral intravenous catheter, wherein the instrument comprises a guidewire, a probe with a sensor, tubing for fluid infusion or blood draw or a light tube for disinfection. 
     
     
         17 . The system of  claim 1 , further comprising a needle assembly removably coupled to the proximal end of the catheter adapter, an introducer needle of the needle assembly extending through the blood control valve. 
     
     
         18 . The system of  claim 1 , wherein the proximal end of the catheter adapter comprises a luer adapter. 
     
     
         19 . The system of  claim 1 , wherein the proximal end of the catheter adapter comprises a non -luer adapter. 
     
     
         20 . The system of  claim 1 , wherein a distal portion of the lumen is narrowed to provide a guide feature.
