The portable medical suction device of the preferred embodiment of the present invention comprises a disposable suction component including a suction tube bonded to the inlet of a plastic flow-through rotary vane pump, a collection tube bonded to the pump outlet and a flexible reservoir bag bonded to the collection tube and having a hydrophobic vent, adapted to be economically disposed of after a single use without the necessity of cleaning the components of the device that contact the aspirate. The rotary vane pump of the disposable component is designed for ready operable coupling and decoupling to the output of an electric motor. The motor is removably mounted in a support frame. The reservoir bag is also gathered within the support frame, having a first volume capacity when so gathered and a second larger volume capacity when unfolded through an opening at one end of the support frame. The motor is energized by a rechargeable battery through an electronic control assembly, each of which is removably mounted in the support frame. The electronic control assembly includes circuitry capable of generating three discrete suction levels for various types of suctioning environments. An AC/DC converter and an external DC power cable are removably housed within the support frame, usable to recharge the battery or drive the motor. The entire suction device is small, lightweight and encased in a padded carrying case having a plurality of readily openable and closeable openings for access to the various components of the suction devce.
