Abstract

A method and 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.

Claims (34)

1. A system for separating a flow of matter comprising:

a flow separation device comprising:

a hollow body comprising a first end, a second end, and an inner volume therebetween;

a suction port disposed at the first end;

a collection port disposed at the second end;

an input port disposed between the first end and the second end and in fluid communication with the inner volume;

a baffle disposed between the input port and the suction port, the baffle comprising a plurality of openings allowing passage of a 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 shaft disposed within the inner volume,

a surgical instrument; and

a suction source;

wherein the input port is configured to receive the flow of matter from the surgical instrument, the flow of matter comprising a gas, a liquid, a solid, or any combination thereof,

wherein the shaft is configured to direct the flow of matter received into the hollow body, and wherein at least a portion of a liquid of the flow of matter exits the hollow body from a port different than a port from which at least a portion of a gas of the flow of matter exits.

2. The system of claim 1 , wherein the shaft directs at least a portion of the flow of matter in a cyclonic pattern along an inner surface of the hollow body.

3. The system of claim 1 , wherein the gas exits the suction port and the liquid exits the collection port.

4. The system of claim 3 , wherein the plurality of openings are distal to the input port.

5. The system of claim 1 , wherein the baffle comprises a tapered section or comprise a plurality of cylindrical sections comprising different diameters.

6. The system of claim 1 , wherein the second end comprises a conical shape.

7. The system of claim 1 , wherein the hollow body comprises a cylindrical shape.

8. The system of claim 1 , wherein the input port is proximal to the suction port and distal from the collection port.

9. The system of claim 1 , wherein the suction port is configured to couple to the suction source.

10. The system of claim 1 , wherein the suction source is a passive suction source.

11. The system of claim 1 , wherein the collection port is configured to couple to a collection container.

12. The system of claim 1 , wherein the flow separation device is attachable or formed therein a collection container.

13. The system of claim 1 , wherein the one or more baffles aids in the separation of gas, of liquid, or a combination thereof from the flow of matter.

14. The system of claim 1 , wherein the input port forms an angle relative to a central axis of the hollow body that is less than 90 degrees forming an angled input port.

15. The system of claim 14 , wherein the angled input port enhances entry of the flow of matter into the angled input port, enhances a cyclonic pattern of flow along an inner surface of the hollow body, or a combination thereof.

16. The system of claim 1 , wherein the flow separation device is configured to enhance a suction capacity of the surgical instrument operatively coupled to the input port.

17. The system of claim 16 , wherein the flow separation device is configured to enhance the suction capacity at least about 1.25 fold compared to a surgical instrument not operatively coupled to a flow separation device.

18. The system of claim 1 , wherein the flow separation device is disposable.

19. The system of claim 1 , further comprising one or more filters, wherein the one or more filters are disposed adjacent to the collection port.

20. The system of claim 19 , wherein a pore size of the one or more filters is less than about 1 micron.

21. The system of claim 19 , wherein the one or more filters are configured to collect one or more solids.

22. The system of claim 1 , further comprising one or more positively charged matrices, one or more negatively charged matrices, or any combination thereof, wherein the one or more positively charged matrices, the one or more negatively charged matrices, or any combination thereof are operatively connected to the suction port.

23. The system of claim 1 , wherein the flow separation device is operatively coupled to one or more suctioning devices, one or more suction sources, one or more canisters, one or more filtration units, one or more charged matrices, or any combination thereof.
