ABSTRACT:
An aspiration unit which will afford a uniform suction level for aspirating fluids from body cavities. The unit is composed of a double piston member, a first head of which is in sealing engagement with a syringe barrel and the second head which is oppositely disposed is contained in a telescoping member which is also receivable in the syringe barrel. Upon movement of the telescoping member outwardly from the syringe barrel, a vacuum will be created in the telescoping member as well as in that portion of the barrel member between the first piston member and the nozzle which is closed from atmosphere by means of a valve member. Upon insertion of a flexible tube into a body cavity and opening of the valve member, fluid will be aspirated into the syringe barrel by means of the partial vacuum created in the syringe barrel and in the telescoping member. A clamp means is provided to hold the telescoping member in the vacuum creating condition while the tubular member is inserted into a body cavity. The aspirating device is operable with one hand and is disposable.
