ABSTRACT:
A surgical suction system which may be driven in a plurality of different ways. The basic component of the system is an enlarged container having an inlet and an outlet and being formed of a resilient material of the type which restores itself to its original shape following distortion from the original shape. The inlet is connected to apparatus for insertion to an area of a patient to be drained and includes a check valve for allowing fluid to pass into the container through the inlet while precluding substantial backflow. The outlet may be connected to a check valve and/or a regulated vacuum source. The walls of the container include pleated formations so that the same may be compressed to reduce the volume to establish a vacuum therein.
