ABSTRACT:
An aspirator for removing vomit and like matter from the mouth and throat. A bellows integral with a collection reservoir includes a handle grip reciprocable alternately to draw vomit into the reservoir from an attached catheter insertable into the throat, and vent air through an exhaust valve. The bellows-reservoir unit is detachably mounted to a frame which also includes a handle grip and springs. The grips are squeezed to draw in vomit, and released to permit the springs to collapse the bellows. The operation is one-handed, the device is portable, and the bellows-reservoir unit can be separated from the frame and discarded after use. A feature is a one-way inlet valve in the catheter to prevent vomit from draining back into the throat during aspirator operation.
