Abstract
A paracentesis catheter system for removing fluids from a patient's abdominal cavity and for administering medication into the abdominal cavity. The catheter system includes a solid stylet, a catheter, a hemostasis valve assembly connected to the catheter, and delivery tubing with a needle connecting the catheter assembly to a stopcock. The stopcock has provisions for connections alternately to a syringe or to a vacuum bottle or drainage bag. The hemostasis valve includes an internal glan, which is compressed to shut off fluid flow through the end of the valve assembly after removing the solid stylet. This causes fluid to be diverted through the side arm tubing and stopcock to a fluid collection container.
