An altered barrel syringe design such as Posi-Flush from BD will
prevent the syringe rebound issue and should work together with the
positive displacement needleless systems, not against each other. Your
problems could be what is happening inside the vein around the tip of
the catheter and not what is happening inside the catheter lumen. Any
piece of technology attached to the catheter will only have an impact
on what is happening inside the catheter lumen. Yet fibrin/thrombus
formation around the catheter tip will cause the same clinical signs -
lack of blood return on aspiration. Lynn

Since I started this thread I am very interested in your questions--can you be brand specific--Are you speaking about the BD posi-flush saline syringe?--We are currently using this product in conjunction with the CLC which is a positive displacement mechanical valve and have had countless withdrawl occlusion issues--Can the physcists or mechanical engineer types out there please explain if these products are working against each other?????????

Hi group:A question for those of you using this device:Do you know for sure the rebound reflux that can be caused by certain syringes when they are 'bottomed out' at the end of the flush cycle is mitigated by this product design?If you DO know that, how was it proven to you?thanks
