Catheter fluid control system
First Claim
1. A tubing network, attachable to an automatic injector device, comprising:
- a fluid bag connector;
a first line connected at one end to the fluid bag connector;
a patient manifold connected to the other end of the first line and connectable to the automatic injector device for fluid communication therewith;
a second line connected at one end to the patient manifold such that the patient manifold is usable to selectively port fluid from either the automatic injector device or the first line, to the second line;
a stopcock capable of performing as a three-way stopcock, connected to a second end of the second line, useable to connect the second line to a catheter;
a waste line attached at a first end to the three-way stopcock such that the waste line is in selectable fluid communication with the second line;
a pump operably connected to a second end of the waste line for taking suction thereon;
a bag line connected at a first end to the pump such that the bag line receives pumped fluid when the pump is operating; and
, a waste bag operably connected to a second end of the bag line.

Abstract
A system and method is provided including a fluid communications network that sends priming and waste fluid to a waste bag, obviating the presence of open fluid containers in an operating room or catheter lab. The fluid communications network is constructed and arranged to allow nearly automated priming and bubble removal, thereby reducing the possibility of operator caused errors in set-up and reducing the time required for set-up. The fluid communications network is useable for attachment to a balloon catheter for inflation thereof. In order to provide greater control and automation of the inflation of the balloon catheter, a conversion kit is provided that can be used to convert an existing automatic injector into an injector useable for automatically controlling the small amount of injection fluid typically associated with balloon catheters.

19. A method of purging air bubbles from a medical tubing network comprising:
-
operably attaching the fluid network to a fluid pump;
causing the fluid pump to send a plurality of pressure waves through the fluid network, thereby causing bubbles adhered to the fluid network to become dislodged;
directing fluid used as a medium to carry said pressure waves to a waste container.

b) receiving actual pressure data;
c) comparing the actual pressure data to baseline pressure data representative of inflation characteristics of the balloon catheter in a controlled environment;
d) adjusting the inflation rate in response to the difference between the actual pressure and the baseline pressure.
