ABSTRACT:
The ventricular drainage system includes an antisiphon device comprising a flow through body which has an interior chamber and which is adapted to be positioned for vertical flow therethrough. The device further includes an inflow tract at the lower end of the body, adapted to be coupled to a ventricular catheter, and an outflow tract at the upper end of said body adapted to be coupled to a drainage tubing. The device also includes a ball in the chamber which is capable of closing the inflow tract when there is no flow of fluid from the ventricular catheter, capable of allowing fluid flow through the body during normal flow of liquid from the catheter and capable of closing the outflow tract upon a rush of fluid from the catheter.
