A suction system, especially for use by a dentist, comprises a corrugated, collapsible waste container (10) having a suction outlet connected to a suction source, such as a small scale piston pump (28), and a suction tube or nozzle (27) connected to a suction inlet of the container. The suction system comprises a holder (17) for selectively retaining the collapsible container in an extended position during use when the suction sources create a sub atmospheric pressure within the container. When a suitable amount of waste material has been separated from the air flowing through the suction nozzle (27) and collected in the container (10) the container may be collapsed and discarded together with the waste collected therein. |
