System and method for flared luer connector for medical tubing

Abstract

Provided is a system and method for a flared luer connector for medical tubing. More specifically, the flared luer connector includes a tube head adapter formed of a resilient material providing an inlet and opposite thereto an outlet with a longitudinal axis there between. A luer lock fitting is formed proximate to the inlet and structured and arranged to engage a syringe, and at least one flared member disposed between the luer lock fitting and the outlet, the flared member rising from the tube head adapter and angled towards the outlet. The flared member also provides at least one engaging surface between the tube head adapter and a distal edge, the engaging surface acutely angled with respect to the longitudinal axis. The engaging surface is structured and arranged to engage with a corresponding receiving section of a base, the base having a deflector section structured and arranged to deflect a tube head adapter having other than the corresponding flared member. An associated method of use is also provided.

         13 . The flared luer connector of  claim 9 , wherein the base is an insert provided to a syringe pump. 
     
     
         14 . The flared luer connector of  claim 9 , wherein the base is a component of a syringe pump. 
     
     
         15 . The flared luer connector of  claim 9 , wherein the tube head adapter further provides at least one gripper structured and arranged for gripping by an operator as the luer lock fitting is engaged with a syringe. 
     
     
         16 . The flared luer connector of  claim 15 , wherein the flared member includes at least one cutout structured and arranged to permit the flared member to pass over each at least one gripper. 
     
     
         17 . The flared luer connector of  claim 9 , wherein the engaging surface is structured and arranged to engage a correspondingly angled receiver section of a base, the base having an angled deflector section structured and arranged to deflect a tube head adapter having a flat disc. 
     
     
         18 . A syringe pump for use with a flared luer connector for medical tubing comprising:
