A suction collection system particularly suitable for drawing fluids from a patient area and storing the fluids for later use or disposal, which is operable in any orientation of the device, thereby providing a field operable system which may be transported in battlefield conditions. The portable suction system consists of a cylindrical evacuating chamber with a top sealing cap. A suction port on the sealing cap is connected to the fluid collection bag, which consists of a laminar flexible plastic bag having an air permeable, liquid impermeable patch or portion through which air may pass for purposes of providing a vacuum suction, yet the collected fluids will remain in the bag. The suction power is provided by a vacuum pump which is electronically regulated by periodically energizing and de-energizing the pump to conserve power supply energy.
A flexible bag for collecting fluids which is adapted to be disposed in a vacuum chamber;
A disposable liquid collection bag for collecting liquid from a suction tube and adapted for fluid tight insertion into a rigid suction chamber;
