Abstract
Abstract A portable suction device for removing fluids blocking aspiration of a patient is disclosed. The device has a housing formed of a soft, but durable, material, a vacuum pump for generating suction, a battery pack for powering the pump, and a fluid container. A tube communicates the pump with the container to evacuate it, and another tube connects the evacuated container with the fluids blocking aspiration of the patient. The housing has a container support integrally attached thereto for supporting the container outside of the housing. The means for supporting is a non-rigid material like that of the housing, and has a closed cell material disposed in the non-rigid material for absorbing shocks to the container.
