We need to figure out the advantage, if any, of using a larger diameter barrel syringe to aspirate fluid and pathology (cells, blood clot & tissue) from a patient using identical size catheters or needles.
Lets ignore that, all things equal, it takes more force to pull back a larger plunger...
Syringe Question
Dear Mordechai9,
Thanks for the help. My question still remains. Let's ignore that it takes more force to pull back a larger plunger.
1. What will the MNP difference be between a barrel with a 29mm and a 40mm diameter if each have an identical 40mm stroke?
2. Will the...
Test
Madpsychic,
How did you hang the weight in your experiment? To pull the plungers out or push them in?
I think based on your test and the other responses, you can say smaller syringes provide bigger negative pressure only for equal pull force on the plunger.
I would like to know...
Negative Pressure With a Syringe
Large syringe barrels are harder to pull back and create suction/negative pressure than smaller barrels. All things equal, we want to know if a larger barrel is better for removing fluid, or viscous fluid and solids, through a catheter.

Take...
