ABSTRACT:
A collection chamber for fluids and a vacuum control device for drainage of the thorax is described. The collection chamber is provided with ports for the attachment of tubing extending from the chest cavity and for connection to a vacuum pump. Instead of using a water level control vacuum regulator this collection chamber uses a system of calibrated holes in the chamber. The vacuum is controlled by calibrating the size of the holes and selectively opening the holes in the chamber to control the force of the vacuum.
