Abstract
A system for separating a flow of matter is shown and described. The system includes one or more flow separation devices, one or more surgical instruments, and one or more suction sources. In some embodiments, the flow of matter comprises biological material. In some embodiments, the flow of matter comprises surgical waste.
Claims17
A flow separation device, comprising:
- a separator body having a cylindrical cavity having a cylindrical wall and first cylindrical cavity end and a second cylindrical cavity end, configured to operate with the first cylindrical cavity end up;
- a conical cavity having a narrow end and a wide end, the wide end mated to the second cylindrical cavity end;
- an input port disposed in the cylindrical cavity wall, configured to receive a flow of matter;
- a suction port mated to the first cylindrical cavity end and configured to couple to a suction source;
- a collection port mated to the narrow end of the conical cavity and configured to couple to a waste deposit;
- a baffle disposed between the input port and the suction port, wherein the baffle comprises a plurality of openings to allow passage of the flow of matter, comprising separated portions thereof, out of the suction port, the baffle being configured to prevent the flow of matter from passing directly from the input port to the suction port without first traversing at least a portion of a circumference of an interior of the cylindrical wall;
- and
- a cylindrical shaft disposed within a center of the cylindrical cavity and configured to direct the flow of matter within the cylindrical cavity.

A liquid-gas flow separator, comprising:
- a cylindrical cavity comprising a cylindrical cavity wall, a first cylindrical cavity end, and a second cylindrical cavity end, the separator configured to operate with the first cylindrical cavity end being up;
- a suction port coupled to a suction source, the suction port being in the first cylindrical cavity end;
- a conical cavity, the conical cavity comprising a wide end and a narrow end, the wide end being mated to the second cylindrical cavity end;
- a collection port at the narrow end of the conical cavity;
- an input port to receive a flow of matter comprising a mixture of liquid and gas, the input port being in the cylindrical cavity wall, the flow of matter induced into the separator by the suction source, the input port configured to direct liquids in the flow the matter to cling to the cylindrical cavity wall;
- a baffle disposed between the input port and the suction port, wherein the baffle comprises a plurality of openings to allow the gasses in the flow of matter to be pulled out of the separator via the suction port, the baffle being configured to prevent liquids in the flow of matter from being pulled directly from the input port to the suction port without traversing at least a first portion of a circumference of the cylindrical cavity wall, the baffle configured to allow gasses in the flow of matter to separate from the liquids in the flow of matter and be pulled out of the separator via the suction port;
- and
- a cylindrical central member disposed within the cylindrical cavity, the central member disposed to form an annular cavity between the cylindrical central member and the cylindrical cavity wall, the liquids in the flow of matter pass through the annular cavity before dropping out the collection port.
