DETAILED DESCRIPTION

While various embodiments have been shown and described herein, it will be obvious to those skilled in the art that such embodiments are provided by way of example only. Numerous variations, changes, and substitutions may occur to those skilled in the art without departing from the subject matter described herein. It should be understood that various alternatives to the embodiments of the subject matter described herein is employed.

FIG. 1 is a block diagram illustrating separator 100. In operation, separator 100 is configured to separate liquids, solids and gasses in a flow of matter. Separator 100 ejects liquids and/or solids separated from the flow of matter out collection port 108 while suctioning at least gasses separated from the flow of matter out suction port 106. Separator 100 is operated by suction received from a suction source. It should be understood that the terms “suction” and “vacuum” as used herein refer to a pressure below the surrounding ambient air pressure.

In some embodiments, separator 100 comprises hollow body 102, input port 104, suction port 106, collection port 108, baffle 110, and shaft 112.

In some embodiments, hollow body 102 comprises a cylindrical wall defining a cylindrical cavity. Other hollow body 102 shapes are suitable for use with the separator 100 including conical shapes and ovoid cylindrical shapes. The hollow body 102 wall may include a first cavity end and a second cavity end. The cavity of hollow body 102 may have a wide end and a narrow end. Hollow body 102 is constructed of a single solid wall that is formed into the hollow body 102 shape, or alternatively, a first wide end of hollow body 102 is mated to a second narrow end of hollow body 102 to form a single hollow body 102 having a narrow section and wide section. In some embodiments, hollow body 102 is configured to operate in an orientation with the first cavity end up. Hollow body 102 is configured to be oriented in operation to allow gravity to pull at least liquid and solids separated from a flow of matter out collection port 108, while gasses separated from the flow of matter are pulled by suction out of suction port 106.

Input port 104 is configured to receive a flow of matter. In some embodiments, input port 104 is integral to hollow body 102. Input port 104 is disposed in the cylindrical cavity wall. Input port 104 is located off-axis from an axis defined by the longitudinal center of the cylindrical cavity.

Input port 104 is configured and positioned to direct a flow of matter received into the hollow body 102 along the internal cavity wall of the hollow body 102. Because, in some embodiments, the hollow body 102 comprises a cylindrical, spherical, or ovoid cylindrical shape, the flow generated within the cavity of the hollow body 102 comprises and essentially cyclonic flow pattern.

By directing the flow of matter along the internal cavity wall of the hollow body 102, forming a cyclonic flow pattern, liquids, solids, and gasses will tend to cling to the wall of the internal cavity wall of hollow body 102 due to the effects of centripetal forces.

A flow of matter is induced into separator 100 by suction received from suction port 106 by a suction or vacuum source. In some embodiments, suction port 106 further comprises a check valve mechanism (not shown in FIG. 1) to, for example, prevent the flow of solids or liquids through suction port 106.

Suction port 106 is configured to couple to a suction source. In certain embodiments, the suction source may include, for example, a vacuum pump, aspirator, and/or a positive pressure operated suction source—such as suction sources that take advantage of Venturi or Coanda effect. Suction from a suction source is transferred from suction port 106 to input port 104. Suction port 106 is disposed near the first cavity end of the hollow body 102. Suction port 106 provides suction received from a suction source for operating separator 100 and may further comprise a check valve. In some embodiments, suction port 106 includes fittings configured to attach tubing. For example, barbed or quick-disconnect type fittings are used to couple tubing to suction port 106. The tubing is, for example, used to couple suction port 106 to a suction source or to an input port 104 of another separator.

Collection port 108 is configured to expel at least liquids and/or solids. Collection port 108 is disposed at the narrow end of the conical cavity of hollow body 102. In some embodiments, collection port 108 is configured to couple to a canister. A canister is used to collect and measure matter received from separator 100. A canister may also be used for the safe collection, transportation and disposal of waste received from separator 100. In some embodiments, collection port 108 is coupled to tubing or piping to direct matter to a waste drain. In some embodiments, collection port 108 may include a mounting ring configured to form a seal between collection port 108 to tubing or a canister.

Baffle 110 is disposed between input port 104 and suction port 106. Baffle 110 is configured to facilitate a cyclonic flow of matter within the hollow cavity 100 by preventing liquids and/or solids in the flow from being pulled directly from input port 104 to suction port 106 without traversing at least a first portion of a circumference of the cylindrical wall of hollow body 102. In some embodiments, baffle 110 includes openings configured to allow at least gasses in a flow of matter to separate from liquids and/or solids that are included in the flow. One or more gasses are pulled through baffle 110 and out suction port 106. In some embodiments, baffle 110 includes a solid surface located proximal to input port 104. The solid surface included in baffle 110 is used to prevent liquids and/or solids in the flow from being pulled directly from input port 104 to suction port 106 by allowing time for gravity to act on the liquids and/or solids before they reach an opening in baffle 110. In some embodiments, a baffle 110 comprises both a solid surface portion and a portion with an opening. In these embodiments, the solid surface portion of the baffle 110 is positioned relative to the input port 104 in such a way that gravity acts on a liquid and/or solid within the cyclonic flow before a suction force through suction port 106 draws the liquid and/or solid out of the opening portion of the baffle 110. The solid surface portion of the baffle 110 is thus configured to prevent suction of liquid and/or solid matter out of suction port 106 while allowing time for gravity to act on the liquids and/or solids as they traverse the solid surface of baffle 110. The effect of gravity within the cavity of the hollow body 102 on liquids and/or solids causes them to generally descend (within the input flow) towards collection port 108 and thereby not be suctioned out of the suction port 106.

Shaft 112 is configured to direct a flow of matter in a cyclonic flow. The cyclonic flow along with gravity cause liquids and solids to separate from gasses included in the flow of matter. In some embodiments, shaft 112 includes a member disposed within the cylindrical cavity of hollow body 102. The member of shaft 112 is positioned within the cavity of hollow body 102 so that the cavity of hollow body 102 surrounding the central member of shaft 112 comprises an annular cavity shape between shaft 112 and hollow body 102 cavity wall.

Shaft 112 is configured to direct liquids and/or solids that are in the flow so that they pass through the annular cavity between the shaft 112 and hollow body 102 cavity wall before dropping out collection port 108. In some embodiments, shaft 112 includes a tapered section or conical end disposed in the cavity of hollow body 102. In some embodiments, shaft 112 includes a plurality of sections having different diameters. The plurality of sections, for example, include a first cylindrical section that defines a first portion of the annular section of the cavity the hollow body 102 and a second section that defines a second portion of the annular cavity. Tapered and cylindrical sections of shaft 112 are configured to direct the flow within hollow body 102 in a cyclonic flow pattern. In some embodiment, baffle 110 is integral to shaft 112.

FIG. 2A is a block diagram illustrating separator and canister system 200. Separator 202 is an example of separator 100; however, separator 202 may include alternative configurations and methods of operation. Separator and canister system 200 may include separator 202 and canister 214.

In some embodiments, separator 202 comprises input port 204, suction port 206, collection port 208, baffle 210 and shaft 212.

In some embodiments, separator 202 comprises a generally cylindrical cavity and a cavity wall. Non-limiting examples of other suitable cavity shapes for separator 202 include spherical and ovoid cylindrical shapes.

Separator 202 is configured to generate a vortex flow within the cavity of separator 202. The cavity of separator 202 includes a first end and a second cavity end. In some embodiments, the cavity is configured to have a wide end and a narrow end. The wide end is coupled to the second end of the generally cavity. In some embodiments, the separator 202 is configured to operate with the first end positioned upwards.

Input port 204 is configured to direct a flow of matter into separator 202. Input port 204 also directs the flow of matter towards shaft 212. The flow of matter may include liquids, solids and gasses, including combinations thereof in varying ratios. Some constituents of the flow of matter may include surgical byproducts. A flow of matter is induced into input port 204 by suction received from a suction source. In some embodiments, input port 204 is integral to separator 202. Input port 204 is disposed in the cavity wall near the first end of the generally cylindrical cavity of separator 202. Input port 204 is disposed off-axis from an axis defined by the longitudinal center of the generally cylindrical cavity of the body. In an embodiment, input port 204 may include fittings such as, barbed or quick-disconnect type fittings, for coupling input port 204 to a suction tip or surgical device. In some embodiments, input port 204 is configured and positioned to generate a vortex of flow within the cavity of the separator 202.

Suction port 206 is configured to couple to a suction source. In certain embodiments, the suction source may include a vacuum pump, aspirator, and/or a positive pressure operated suction source—such as suction sources that take advantage of Venturi or Coanda effect. Suction from a suction source is transferred from suction port 206 to input port 204. Suction port 206 is disposed near the first cylindrical cavity end. Suction port 206 provides suction received from a suction source for operating separator and canister system 200. In some embodiments, suction port 206 may include fittings configured to attach tubing. For example, barbed or quick-disconnect type fittings are used to couple tubing to suction port 206. The tubing is used to couple suction port 206 to a suction source or to an input port 204 of another separator.

Collection port 208 is configured to expel at least liquids and/or solids separated from a flow of matter received at input port 204. Collection port 208 is disposed at the narrow end of the conical cavity of the hollow body of separator 202. Collection port 208 is configured to couple separator 202 to canister 214. In some embodiments, collection port 208 includes a mounting ring configured to form a seal when separator 202 is coupled to canister 214, tubing, piping or some other element configured to dispose of at least liquids and/or solids. In some embodiments, collection port 208 may include fittings, such as barbed or quick disconnect type fittings for, for coupling collection port 208 to canister 214 or tubing.

Baffle 210 is configured to allow gasses to be pulled out suction port 206 from liquids and/or solids in a flow of matter received at input port 204. Baffle 210 is configured to prevent liquids or solids in a flow of matter received at input port 204 from being pulled directly from input port 204 to suction port 206 without traversing at least a first portion of a circumference of separator 202. Baffle 210 is disposed between input port 204 and suction port 206. In an embodiment, baffle 210 includes a plurality of openings to allow at least the gasses in a flow of matter to be pulled out suction port 206. In an embodiment, baffle 210 includes a solid surface located proximal to input port 204. The solid surface is configured to prevent liquids and/or solids in a flow of matter from being pulled directly from input port 204 to suction port 206 without first traversing at least a portion of separator 202 as described with reference to FIG. 1.

Shaft 212 is configured to form an annular cavity between shaft 212 and separator 202 within the cavity of separator 202. In some embodiments, shaft 212 includes a cylindrical central member disposed within the generally cylindrical cavity of separator 202. Shaft 212 is configured to generate a vortex flow within separator 202. The vortex flow and gravity cause liquids and/or solids in a flow of matter received at input port 204 to separate from gasses. Liquids and gases within the matter flow are expelled out suction port 206. In an embodiment, shaft 212 may include a tapered section disposed near the conical cavity of separator 202. In some embodiments, shaft 212 may include a plurality of cylindrical sections having different diameters. In some embodiments, the plurality of cylindrical sections may include a first section that defines a first portion of the annular cavity and a second section that defines a second portion of the annular cavity. In some embodiments, baffle 210 is integral to shaft 212.

Canister 214 is configured to receive waste from separator 202. The waste may include at least liquids and/or solids separated from a flow of matter received at input port 204. Canister 214 is used to measure the amount of liquids and/or solids separated from the flow of matter received at input port 204. Canister 214 is configured to permit the safe collection, transportation and disposal of waste. In some embodiments, canister 214 may include a valve configured to activate when canister 214 is filled to a pre-determined volume. The valve is used to prevent waste from leaving canister 214 during transportation. In some embodiments, canister 214 may include a commercially available canister.

FIG. 2B is a diagram illustrating the operation of separator and canister system 200. In addition to the elements illustrated in FIG. 2A, FIG. 2B includes input flow 240, suction flow 242 and collection flow 244.

In operation, a suction source is coupled to suction port 206 to generate suction flow 242. The suction source may include a vacuum pump, aspirator or a Coanda based suction generator. Suction flow 242 generates a flow within separator 202. Suction flow 242 induces input flow 240 to enter input port 204. Input flow 240 may include liquids, solids, and gasses, including combinations thereof in varying ratios. Some constituents of input flow 240 may include surgical byproducts. Suction flow 242 may generate a cyclonic or vortex flow within separator 202 in order to separate liquids, solids and gasses from input flow 240.

Shaft 212 in conjunction with separator 202 is configured to generate a cyclonic or vortex flow from input flow 240 using suction flow 242. Baffle 210 may prevent input flow 240 from passing directly from input port 204 to suction port 206 without first traversing at least a portion of separator 202. The cyclonic flow, along with gravity, separates collection flow 244 and suction flow 242 from input flow 240. One or more gasses are separated from input flow 240 is pulled out suction port 206 as suction flow 242.

Suction flow 242 is directed out of separator 202 by suction port 206. Suction port 206 is configured to exhaust at least suction flow 242 from separator 202. In some methods of operation, suction port 206 expels input flow 240, unseparated, out of suction port 206.

Collection flow 244 is directed out of collection port 208. Collection port 208 is configured to expel at least collection flow 244 from separator 202. Collection port 208 is configured to direct collection flow 244 to canister 214.

In some embodiments, canister 214 is connected to a suction source (not shown). The suction transferred to canister 214 from the suction source provides an additional pull on the fluid and solid matter in separator 202 (i.e. in addition to gravity) to facilitate separation of liquid and solid matter (drawn into canister 214) from gas (drawn out through suction port 206).

FIG. 3 is a diagram illustrating a method of operating a separator and canister system. The steps illustrated in FIG. 3 is performed by, for example, one or more elements of separator and canister system 200.

In a step 302, a suction source is applied to a suction port. In some embodiments, said suction port is part of a separator system as described herein. In some embodiments, a user connects a suction port to a suction source that comprises an air amplifier based on a Coanda or Venturi effect. In some embodiments, the suction is applied to a suction port of a device configured to separate suctioned matter that was suctioned from a surgical field during a surgical procedure. As applied but not limited to canister system 200, a separator 202 includes suction port 206. Suction port 206 is configured to couple to a suction source capable of providing suction flow 242. A suction source is configured to apply suction flow 242.

In a step 304 a cyclonic or vortex flow is generated by a separator such, as for example, separator 100 or separator 200. A cyclonic or vortex flow is generated from a suction flow applied to a suction port of a separator. In some embodiments, a cyclonic or vortex suction flow is generated when air within the separator is suctioned through the suction port as a result of an application of a suction flow. A shaft within the separator cavity is configured to create a cyclonic flow within the separator, and air within the separator cavity that is suctioned out with the initial application of suction to the separator is drawn around the shaft to form a cyclonic or vortex flow. In some embodiments, the shaft further comprises a conical head that further promotes cyclonic flow. In some embodiments, the cyclonic or vortex flow of suction causes matter comprising a solid, a liquid, a gas, or a combination thereof to be drawn into the separator in a cyclonic or vortex input flow. In some embodiments, the position of the input port further aids in generating a cyclonic or vortex flow of an input flow. In some embodiments, the inlet port is positioned towards the upper portion of the separator. In some embodiments, the inlet port is positioned at an angle such that it directs an inflow essentially directly against an interior wall surface of the separator cavity. As applied but not limited to system 200, separator 202 is configured to generate, from suction flow 242, a cyclonic flow of matter that is received via input port 204.

In a step 306, an input flow is received via an input port. Suction flow generates suction at an input port. Suction flow is at a pressure below an ambient air pressure. Therefore, a suction flow causes input flow which is at around ambient pressure to be received at an input port of the separator device. In some embodiments, the input flow comprises a solid, liquid, a gas, or a combination thereof. In some embodiments, the input flow travels in a cyclone or vortex flow pattern within the separator. As applied but not limited to system 200, input port 204 is configured to receive input flow 240. Suction flow 242 generates suction at input port 204. Suction flow 242 is at a pressure below an ambient air pressure. Therefore, suction flow 242 causes input flow 240 to be received at input port 204.

In a step 308, the components of an input flow comprising a mixture of a solid and/or a liquid with a gas are separated. For example, a separator is configured to separate a solid and/or liquid from a gas of an input flow by directing the heavier constituents (i.e., liquids and/or solids) of the input flow into a cyclonic flow pattern that gravity acts upon to cause these heavier constituents to exit via collection port, while the lighter constituents (i.e. gasses, smoke, aerosols) in the input flow is pulled out of separator by the suction at the suction port. Thus, a collection flow that is released from the separator via a collection port includes at least liquids and/or solids. As applied but not limited to system 200, separator 202 is configured to separate collection flow 244 from input flow 240 by directing the heavier constituents (i.e., liquids and solids) of input flow 240 into a cyclonic flow pattern that gravity acts upon to cause these heavier constituents to exit via collection port 208, while the lighter constituents (i.e. gasses, smoke, aerosols) in input flow 240 are pulled out of separator 202 by the suction at suction port 206. Thus, collection flow 244 includes at least liquids and/or solids.

In a step 310, the separated solid and/or liquid from the input flow are directed into a collection port. For example, a collection port is configured to receive the heavier constituents and direct them to a canister. Liquids and/or solids are collected in a canister. For example, a canister is configured to receive a collection flow (which may include liquids and/or solids) from collection port. As applied but not limited to system 200, collection port 208 is configured to receive the heavier constituents and direct them to collection canister 214.

In a step 312, the separated solid and/or liquid is collected in a collection canister. As applied but not limited to system 200, collection canister 214 is configured to receive collection flow 244 (which may include liquids and solids) from collection port 208.

In a step 314, gasses are suctioned through a suction port. For example, a suction flow may include gasses drawn out of an input flow. Suction port is configured to allow suction flow to be suctioned through suction port. In some embodiments, a separator further comprises a baffle that prevents liquids and/or solids within an input flow to be suctioned from the suction port by the suction flow. As applied but not limited to system 200, suction flow 242 may include gasses. Suction port 206 is configured to allow suction flow 242 to be suctioned through suction port 206.

FIG. 4A is a block diagram illustrating separator system 400. In this embodiment, one or more separator systems are aligned in series. As shown, separator 402 and separator 422 are examples of separator 202; however separator 402 and separator 422 may include alternative configurations and methods of operation.

In some embodiments, separator system 400 may, for example, include separator 402, canister 414, separator 422, canister 434 and suction source 416.

Separator 402 is configured to generate a vortex flow within the cavity of separator 402. The cavity of separator 402 includes a first end and a second cavity end. In some embodiments, the cavity is configured to have a wide end and a narrow end. The wide end is coupled to the second end of the generally cavity. In some embodiments, the separator 402 is configured to operate with the first end positioned upwards.

Input port 404 is configured to direct a flow of matter into separator 402. Input port 404 directs the flow of matter towards shaft 412. The flow of matter may include liquids, solids and gasses, including combinations thereof in varying ratios. Some constituents of the flow of matter may include surgical byproducts. A flow of matter is induced into input port 404 by suction received from a suction source. In some embodiments, input port 404 is integral to separator 402. Input port 404 is disposed in the cavity wall near the first end of the generally cylindrical cavity of separator 402. Input port 404 is disposed off-axis from an axis defined by the longitudinal center of the generally cylindrical cavity of the body. In an embodiment, input port 404 may include fittings such as, barbed or quick-disconnect type fittings, for coupling input port 404 to a suction tip or surgical device. In some embodiments, input port 404 is configured and positioned to generate a vortex of flow within the cavity of the separator 402.

Suction port 406 is configured to couple to a suction source. In certain embodiments, the suction source may include a vacuum pump, aspirator, and/or a positive pressure operated suction source—such as suction sources that take advantage of Venturi or Coanda effect. Suction from a suction source is transferred from suction port 406 to input port 204. Suction port 406 is disposed near the first cylindrical cavity end. Suction port 406 may provide suction received from a suction source for operating separator and canister system 400. In some embodiments, suction port 406 may include fittings configured to attach tubing. For example, barbed or quick-disconnect type fittings are used to couple tubing to suction port 406. The tubing is used to couple suction port 406 to a suction source or to an input port 404 of another separator.

Collection port 408 is configured to expel at least liquids and/or solids separated from a flow of matter received at input port 404. Collection port 408 is disposed at the narrow end of the conical cavity of the hollow body of separator 402. Collection port 408 is configured to couple separator 402 to canister 414.

Baffle 410 is disposed between input port 404 and suction port 406. In some embodiments, baffle 410 includes a plurality of openings to allow at least the gasses in a flow of matter to be pulled out suction port 406. In some embodiments, baffle 410 includes a solid surface located proximal to input port 404. The solid surface is configured to prevent liquids and/or solids in a flow of matter from being pulled directly from input port 404 to suction port 406 without first traversing at least a portion of separator 402 as described with reference to FIG. 1.

Shaft 412 is configured to form an annular cavity between shaft 412 and separator 402 within the cavity of separator 402. In some embodiments, shaft 412 includes a cylindrical central member disposed within the generally cylindrical cavity of separator 402. Shaft 412 is configured to generate a vortex flow within separator 402. The vortex flow and gravity cause liquids and/or solids in a flow of matter received at input port 404 to separate from gasses. Liquids and gases within the matter flow are expelled out suction port 406. In an embodiment, shaft 412 includes a tapered section disposed near the conical cavity of separator 402. In some embodiments, shaft 412 includes a plurality of cylindrical sections having different diameters. In some embodiments, the plurality of cylindrical sections includes a first section that defines a first portion of the annular cavity and a second section that defines a second portion of the annular cavity. In some embodiments, baffle 410 is integral to shaft 412.

Canister 414 is configured to receive waste from separator 402. The waste may include at least liquids and/or solids separated from a flow of matter received at input port 404. Canister 414 is used to measure the amount of liquids and/or solids separated from the flow of matter received at input port 404. Canister 414 is configured to permit the safe collection, transportation and disposal of waste. In some embodiments, canister 414 may include a valve configured to activate when canister 414 is filled to a pre-determined volume. The valve is used to prevent waste from leaving canister 414 during transportation. In some embodiments, canister 414 may include a commercially available canister.

Separator 422 may include similar configurations and methods of operation as separator 402. For the sake of brevity, separator 422 will not be described further. Likewise collection canister 434 may include similar configurations and methods of operation as collection canister 414. For the sake of brevity, collection canister 434 will not be described further.

Separator system 400 includes suction source 416. Suction source 416 may be any device configured to generate a pressure below an ambient air pressure. Suction source 416 may include a vacuum pump, aspirator or Coanda based positive pressure operated suction source.

FIG. 4B is a block diagram illustrating an exemplary operation of separator system 400 in a first mode. Separators 402, 422 are configured to direct input flow 440 directly from input port 404 out suction port 406 when canister 414 reaches a predetermined fill volume. As illustrated in FIG. 4B, canister 414 may not have reached a predetermined fill volume. Fill volume 436 is less than the predetermined fill volume.

In operation, suction source 416 supplies suction flow 442 to suction port 426. Separator 422 is configured to transfer suction flow 442 to separator 402. Suction flow 442 creates a pressure near input port 404 that is below an ambient air pressure. The ambient air pressure overcomes the pressure of suction flow 442 thereby inducing input flow 440 into input port 404. Input port 404 is configured to receive input flow 440. Input flow 440 comprises liquids, gasses and solids, including combinations thereof in varying ratios. Input flow 440 may include surgical byproducts. Shaft 412, in combination with an interior cavity of separator 402, creates a cyclonic flow within separator 402 from suction flow 442. The cyclonic flow and gravity causes collection flow 444 to separate from input flow 440. Collection flow 444 comprises at least liquids and/or solids. Collection flow 444 is expelled from collection port 408. Collection port 408 is configured to direct collection flow 444 to canister 444.

Fill volume 436 represents a volume of collection flow 444 contained in canister 414. As illustrated in FIG. 4B, fill volume 436 may not have reached a predetermined fill volume. In this case, separator 402 operates in a first mode of operation. Separator 402 separates suction flow 442 from collection flow 444. In the first mode of operation, suction flow 442 comprises primarily gasses separated from input flow 440.

Suction flow 442 is pulled from separator 402 by suction source 416. Suction flow 442 is passed from suction port 406 to input port 424. Suction flow 442 may comprise primarily liquids and gasses. Separator 402 continues to operate in the first mode of operation until fill volume 436 reaches a predetermined volume.

In some embodiments, separator system 400 comprises a connection between canisters 414 and 434 (not shown). The connection between canisters is configured to transfer a suction force between canister 434 to canister 414 and may comprise any of the means of transmitting suction described herein including, for example, suction tubing. In this embodiment, suction generated by suction source 416 is transmitted to canister 434 of separator 442 and then through the connection between the canisters the suction is transmitted to canister 414. The suction transferred to canister 414 provides an additional pull on the fluid and solid matter in separator 402 (i.e. in addition to gravity) to facilitate separation of liquid and solid matter (drawn into canister 414) from gas (drawn out through suction port 406).

FIG. 4C is a block diagram illustrating an exemplary operation of separator system 400 in a second mode. Separators 402, 422 are configured to pass input flow 440 from input ports 404, 424 to suction ports 406, 426 unseparated when canisters 414, 434 reach predetermined fill volumes. As illustrated in FIG. 4C, fill volume 436 has reached a predetermined fill volume for canister 414. In a second mode of operation, separator 402 passes input flow 440 through suction port 406 to separator 422 unseparated.

In operation, suction source 416 is configured to supply a suction flow 442 to suction port 426. Separator 422 is configured to pass suction flow 442 to separator 402. Suction flow 442 pulls input flow 440 into input port 404. Separator 402 passes input flow 440 from input port 404 to suction port 406 because fill volume 436 has reached a predetermined fill volume for canister 414. Input flow 440 is received by input port 424.

Fill volume 438, as shown, has not reached a predetermined fill volume for canister 434. Separator 422 therefore separates collection flow 444 from suction flow 442. Collection flow 444 may comprise liquids and/or solids from input flow 440. Separator 422 separates suction flow 442 from collection flow 444. Collection flow 444 is expelled out collection port 428. Collection port 428 is coupled to canister 434. Canister 434 is configured to receive collection flow 444 from collection port 428. Suction flow 442 is pulled out suction port 426 by suction source 416.

The systems, devices, and methods described herein are configured to separate a gas from a liquid at a controlled rate. The controlled rate of suction applied by a system increases when one or more flow separation devices are connected as described herein.

FIG. 5 is a diagram illustrating an exemplary method of operating a separator system in series. The steps illustrated in FIG. 5 is performed by, for example, one or more elements of separator system 400.

In steps 502 and 504, a single suction source applies suction to a suction port of a second separator which is connected to a first separator. The first separator is connected to the second separator such that a suction flow generated within the second separator is translated to the first separator. In some embodiments, the input port of the second separator is connected to the suction port of the first separator by a suction conduit such as standard suction tubing. A suction source is directly applied to a suction port of a second separator generating a suction flow that is transmitted to the first separator. As applied but not limited to system 400, suction source 416 is configured to supply suction. Suction port 426 is configured to receive suction flow 442 from suction source 416.

As applied but not limited to system 400, separator 402 is configured to separate suction flow 442 by directing the heavier constituents (i.e., liquids and solids) of input flow 440 into a cyclonic flow pattern that gravity acts upon to cause these heavier constituents to exit via collection port 408, while the lighter constituents (i.e., gasses, smoke, aerosols) in input flow 440 are pulled out of separator 402 by the suction at suction port 406. Thus, collection flow 444 includes at least liquids and solids.

In a step 512, liquids and/or solids from the first separator is collected. For example, as described, a collection port is configured to receive the heavier constituents and direct them to a canister. As applied but not limited to system 400, collection port 408 is configured to receive the heavier constituents and direct them to collection canister 414. Separator 402 is coupled to collection canister 414. Collection canister 414 is configured to receive collection flow 444 from collection port 408.

Biological filter 1356 may comprise mechanical, biological, chemical or other types of filters including any combination thereof to trap biological elements. Mechanical filtration may include physical barrier or filter media type filters including combinations thereof

Filters using a physical barrier or filter media retain biological elements by physically blocking the biological elements from passing through the filter media. Filter media mechanically or physically strains biological elements from the effluent passing through it. Filter media is available in a variety of materials and porosities, which may be selected to limit the size of biological elements they can extract. Combinations of different materials and porosities of filter media may be used to separate specific elements comprising an effluent of the collected matter and the gasses received via input port 11304 out suction port 1306.

Biological filter 1356 may be configured to use living microorganisms, such as bacteria and fungi, to capture and biologically degrade pollutants, harmful chemicals and other undesirable content from an effluent. Biological filtration can be used with gases and liquids. Biological filters comprise a filter media on which beneficial microorganisms grow. Biological filter media can be made from sand, plastic, metals, ceramics and other materials. Materials having a large surface area to volume ratio typically provide the best performance in biological filters.

Biological filter 1356 may be configured to use chemical filtration media to removes dissolved particulates from an effluent via activated carbons, resins, and other adsorbents. Chemical filtration media causes unwanted dissolved matter to adhere to it. Two popular forms of chemical media include activated carbon and resins. Activated carbon has microscopic pores that allow certain organic or inorganic materials to stick to them. Carbon removes many harmful elements from an effluent. Ion exchange resins work by attracting a specific molecule to adhere to them. Resins can be combined with carbon. The resins often strengthen the filtering ability of the carbon. Protein foam skimming or oxidation with ozone may also be used for chemical filtration.

FIG. 15 is a block diagram illustrating separator 1500. In operation, separator 1500 is configured to separate liquids, solids and gasses in a flow of matter. Separator 1500 ejects liquids and solids separated from the flow of matter out collection port 1508 while suctioning at least gasses separated from the flow of matter out suction port 1506. Separator 1500 is operated by suction received from a suction source. It should be understood that the terms “suction” and “vacuum” as used herein refer to a pressure below the surrounding ambient air pressure.

In some embodiments, separator 1500 includes separator body 1502, input port 1504, suction port 1506, collection port 1508, baffle 1510 and vortex element 1512.

Separator body 1502 includes a cylindrical wall defining a cylindrical cavity. The cylindrical wall includes a first cylindrical cavity end and a second cylindrical cavity end. Separator body 1502 also forms a conical cavity. The conical cavity has a wide end and a narrow end. The wide end is mated to the second cylindrical cavity end of separator body 1502. In some embodiments, separator body 1502 is configured to operate with the first cylindrical cavity end up. Separator body 1502 is configured to allow gravity to pull at least liquid and solids separated from a flow of matter out collection port 1508, while gasses separated from the flow of matter are pulled by suction out of suction port 1506.

Input port 1504 is configured to receive a flow of matter. In some embodiments, input port 1504 may be integral to separator body 1502. Input port 1504 may be disposed in the cylindrical cavity wall. Input port 1504 may be located off-axis from an axis defined by the longitudinal center of the cylindrical cavity. Input port 1504 may be configured to direct a flow of matter along the cylindrical cavity wall. By directing the flow of matter along the cylindrical cavity wall, liquids and gasses may cling to the wall of the cavity due to the effects of centripetal forces. The flow of matter may be induced into separator 1500 by suction received from suction port 1506 by a suction or vacuum source.

Input port 1504 includes angle 1560. Angle 1560 represents an angle between a longitudinal axis located at the center in input port 1504 and a longitudinal axis located at the center of separator body 1502. In some embodiments, angle 1560 may equal 90°. In some embodiments, angle 1560 may be an acute angle. When angle 1560 is an acute angle, a flow of matter entering input port 1504 is directed away from baffle 1510 and towards collection port 1508. Angle 1560 may improve the operating efficiency of separator 1500 by directing the flow of matter. Angle 1560 may prevent liquids and solids from exiting suction port 1506 without first traversing at least a portion of an inner circumference of separator body 1502.

Suction port 1506 is configured to couple to a suction source. In certain embodiments, the suction source may include a vacuum pump, aspirator, and/or a positive pressure operated suction source—such as suction sources that take advantage of Venturi or Coanda effect.

The suction provided by the suction source 1916 facilitates separation of a gas from a solid and/or liquid suction flow within the separator 1902 as described herein. In some embodiments, the gas comprises surgical smoke generated by an electrocautery instrument. In some embodiments, surgical smoke that is separated with separator 1902 is evacuated into a trap. In some embodiments, surgical smoke that is separated with separator 1902 is passed through a filter or series of filters configured to trap toxic particles and or biological elements (e.g. viruses) within the smoke. Suction attachment 1946 may comprise, for example, a suction tip such as for example, a Yankauer tip. Suction attachment 1946 is used by a surgeon to suction material from a surgical field which includes, for example, blood, fat, pus, irrigation fluid, bone, surgical smoke, and other similar organic and inorganic materials. Materials suctioned from the surgical field are transmitted to the separator 1902 through input tubing 1930. As described herein, the material suctioned through the surgical suction instrument is separated in the separator 1902 so that a gas (e.g. surgical smoke) is drawn out through the top of the separator 1902 and any liquid and/or solid material is drawn by gravity (and/or suction) into the canister 1914. It should be understood that while one canister and separator are shown, surgical system 1900 may also be configured for use with two or more separators either in series or in parallel as described herein.

A system may comprise a surgical instrument, a suction source, and one or more separators. The one or more separators may be operatively connected in series, such as connected via tubing. In some cases, the system may also comprise collection canisters attachable to each of the one or more separators. In some cases, at least one of the one or more separators comprises a canister formed therein. A system comprising one or more separators in series may permit filling a volume of a first canister in the series with a liquid of the flow of matter followed by filling a volume of a second canister in the series with a liquid of the flow of matter followed by filling a volume of a third canister in the series and so on.

A second canister may not be filled with a liquid from the flow of matter until at least a portion of the volume of the first canister is filled. A third canister may not be filled with a liquid until at least a portion of the volume of the second canister and the first canister are filled. The portion filled with liquid may be about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 96%, about 97%, about 98%, about 99%, or 100% of the total canister volume. The portion filled with liquid may be at least about 70% of the total canister volume. The portion filled may be at least about 80% of the total canister volume. The portion filled may be at least about 80% of the total canister volume. The portion filled may be at least about 90% of the total canister volume. The portion filled may be at least about 95% of the total canister volume.

When a portion of the volume of a first canister, such as about 90%, is filled with liquid, the flow of matter may be automatically directed to the second separator in the series to fill the second canister. When a portion of the volume of the first canister and the second canister is filled with liquid, the flow of matter may be automatically directed to the third separator in the series to separate gas and liquid from the flow of matter and to fill the third canister. A system of separators in series may permit the collection of liquids from a flow of matter into a series of canisters and separation of gas from the flow of matter during continuous suction use of the surgical instrument. A system of separators in series permits continuous suction use of the surgical instrument with a greater liquid collection volume compared to a single separator.

FIG. 20A shows an embodiment of a separator coupled with a canister top. In the shown embodiment, the separator interface with the canister top provides for forgoing the convergence at the bottom of the separator, so that the separator maintains its widest diameter and empties directly into the canister at its widest diameter (i.e. without tapering of separator to form a smaller exit port). In some embodiments, the canister top is configured to receive and couple with a wider diameter exit (i.e. opening) of a separator as shown. In some embodiments, the canister top and the separator are fused to form one continuous piece.

FIG. 20B shows an exploded view of the separator components as described herein. It should be understood that the embodiment of the separator and canister top shown in FIGS. 20A and 20B are configured to be used with any and all devices, systems, and methods described herein.

In some embodiments, a flow separation device (i.e. a separator) is operatively coupled to a canister. In some embodiments, a flow separation device is retrofitted to an existing canister. In some embodiments, a flow separation device is integrated into a canister.

In some embodiments, a flow of matter enters the flow separation device from the surgical instrument at the input port. The flow of matter may comprise a gas, a liquid, a solid, or any combination thereof. The flow separation device enhances the suction capacity of the surgical instrument compared to a surgical instrument without a flow separation device operatively coupled. The flow separation device enhances the suction capacity of a suction source, such as a passive suction source, compared to a system without a flow separation device operatively coupled. The flow separation device is configured to separate the gas, the liquid, the solid, or any combination thereof. The gas exits the flow separation device from a different port that the liquid exits. For example, the gas exits the suction port and the fluid exits the collection port. In some embodiments, a liquid exiting the collection port of the flow separation device is collected in a canister, such as a collection canister, that is operatively coupled to the flow separation device. The solid is collected in one or more filters of the flow separation device. In some embodiments, the solid also exits the collection port with the liquid.

The system may include one or more valves, such as a shut off valve, a ball valve, a butterfly valve, a clapper valve, a check valve, a choke valve, a diaphragm valve, a gate valve, a pinch valve, a piston valve, a plug valve, a poppet valve, a safety valve, or any combination thereof. The one or more valves is operatively coupled to the flow separation device, the surgical instrument, the suction source, or any combination thereof. One or more valves are included as a safety feature of the system. One or more valves are included to optimize performance of the system. For example, a shut off valve may shut off the system if a volume of liquid within the flow separation device exceeds a specified volume, such as a volume greater than 70%, 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99% or greater the total inner volume of the hollow body of the flow separation device. A shut off valve may shut off the system if a volume of liquid within the flow separation device exceeds a volume greater than 70% the total inner volume of the hollow body of the flow separation device. A shut off valve may shut off the system if a volume of liquid within the flow separation device exceeds a volume greater than 80% the total inner volume of the hollow body of the flow separation device. A shut off valve may shut off the system if a volume of liquid within the flow separation device causes the liquid to begin to exit all ports of the flow separation device.

FIGS. 21A, 21B, and 21C show an embodiment of the separator wherein the input port of the separator at an angle relative to a central axis of the hollow body that is less than 90 degrees. In some embodiments, the input port is angled relative to the central axis at about 85°, 80+, 75°, 70°, 65°, 60°, 55°, 50°, 45°, 40°, 35°, 30°, 25°, 20° or less. In some embodiments, the input port is angled at about 70° or less. In some embodiments, he input port is angled at about 60° or less. The input port is angled at about 50° or less. In some embodiments, the input port is angled at about 40° or less. In some embodiments, the input port is angled at about 30° or less. In some embodiments, the input port is angled from about 20° to about 50°. In some embodiments, the input port is angled from about 40° to about 70°. In some embodiments, the input port of the separator is angled to enhance entry of the flow of matter into the input port, enhance a cyclonic pattern of flow along an inner surface of the hollow body, or enhance movement of liquid towards the collection port, or any combination thereof. In some embodiments, the cyclonic pattern of flow along an inner surface of the hollow body may aid in separation of a gas from a liquid of the flow of matter. In some embodiments, the input port of the separator is configured to direct a flow entering the separator against the wall of the separator as the flow enters the separator.

FIG. 21D shows a bottom view of an embodiment wherein an input port opening enters the separator and contacts the central column (or shaft) of the separator. Typically fluid traveling from a smaller diameter conduit into a larger diameter conduit tends to expand at the point of intersection of the smaller conduit with the larger conduit. Here, as shown the opening of the input port enters into the larger diameter interior of the separator so that fluid expansion is decreased (as compared to, for example, an input port that opens directly into a larger conduit). Also shown, the opening of the input port is shaped so that a side of the input port opening extends and contacts the central column (or shaft) while the opening gradually curves away from that point so that the edge of the opening tapers away from the point at which the opening of the input port contacts the central column. This configuration directs flow of liquid and/solid suction material against the inner surface of the separator while the contact of the input port with the column tends to draw the flow of gaseous components in the suction flow around the central column due to a Coanda effect. The initial separation of the gas and fluid due to the shape and positon of the input port as shown in FIG. 21D enhances the separation as described herein.

FIGS. 22A and 22B show a side view and bottom view respectively of an input port opening into a separator wherein the opening contacts the central column (or shaft). Unlike the embodiment shown in FIG. 21D the opening of the input port is essentially flat without any taper. Similar to the embodiment shown in FIG. 21D, a gaseous component of a suction flow will tend to be drawn to around the central column of the separator when the suction flow enters the separator due to the Coanda effect. Because the opening of the input port opens into the separator, as in FIG. 21D, there will be a decrease or prevention of expansion of the suction flow as it leaves the input port.

Also shown in FIGS. 21D, and 22B, a baffle comprises a solid surface that is proximal to the opening of the input port. Thus, openings in the baffle do not extend around the entire circumference of the baffle. The solid surface of the baffle and its position immediately proximal to the opening of the input port blocks liquids and or/solids entering the separator so that the liquids and/or solids are not immediately drawn up and out of the suction port of the separator. Rather blocking the initial escape of solid and/or liquid components of the suction flow by the solid portion of the baffle allows for gravity (and/or suction from the direction of the canister) to draw the liquids and/or solids down towards the bottom of the separator. The gaseous components of the mixture are also initially blocked by the solid component of the baffle but these components are affected more strongly by the suction force through the suction port (i.e. more strongly than gravity and/or a suction force from the direction of the canister) which draws the gaseous components up and out of the separator through the holes in the baffle which are positioned past the solid portion of the baffle.

It should be understood that embodiments of baffles with a solid portion near an input port may be used with any and all devices, systems, and methods described herein.

In some embodiments, the separator comprises one or more baffles. The one or more baffles may individually comprise a plurality of openings. The plurality of openings may comprise 3, 4, 5, 6, 7, 8, 9, 10, or more openings. In some embodiments, the plurality of openings is 3. In some embodiments, the plurality of openings is 4. In some embodiments, the plurality of openings is 5. In some embodiments, the plurality of openings is 6. In some embodiments, the plurality of openings is 7. In some embodiments, the plurality of openings is 8. In some embodiments, the plurality of openings is 9. In some embodiments, the plurality of openings is 10. In some embodiments, the plurality of openings is positioned on the one or more baffles such that they are distal to the input port. In some embodiments, the one or more baffles is positioned on a first end of the shaft that is adjacent a second conical end. In some embodiments, the one or more baffles are configured to receive at least a portion of the flow of matter to pass through the one or more openings. In some embodiments, the one or more baffles are configured to aid in the separation of gas from liquid of the flow of matter entering the separator.

FIG. 23A-23D show different views of a baffle coupled with helical surface. In some embodiments, a baffle may be shaped or coupled with a helix. The helix is configured to guide the flow of the liquid and/or solid components within the suction flow along a helical track down towards the bottom (i.e. the exit port) of the separator. A helical baffle may be right-handed or left-handed. The helical baffle may be a conical helix, a circular helix, a cylindrical helix, or other. A helical baffle may form a single complete rotation about the shaft. A helical baffle may form a single complete rotation about the hollow body. A helical baffle may form more than one complete rotation about the shaft. A helical baffle may form rotations along a portion of the shaft. A helical baffle may form rotations along a portion of the hollow body.

A shaft may be integrated into a separator or attachable thereto an inner portion of the hollow body of the separator.

A shaft may comprise one or more openings. An opening in a shaft may permit one or more gases to exit the hollow body, such as via the hollow lumen of the shaft towards the suction port. An opening on the shaft may be a circumferential gap space, such as an annular opening. An opening on the shaft may be positioned distal to the input port. An opening on the shaft may be positioned on a portion of the bulbous end.

The shaft may comprise one or more circumferential cross-section areas along the length of the shaft. Circumferential cross-section areas along the length of the shaft may be the same. Circumferential cross-section areas along the length of the shaft may vary. For example, the varied circumferential cross-section areas may form a shaft with a bulbous end, a protruding end, a spherical end, or other. Varying the circumferential cross-section areas along the shaft may enhance laminar flow within the hollow body, may reduce eddy currents, may prevent flow convergence, may prevent flow divergence, or any combination thereof. For example, a shaft comprising a bulbous end positioned adjacent to a port, such as a collection port, having a circumferential cross-section area that is different than the circumferential cross-section area of the hollow body, may enhance laminar flow within the hollow body, may reduce eddy currents, may prevent flow convergence, may prevent flow divergence, or any combination thereof.

In some cases, the flow of matter may enter the inner volume via an input port. A baffle may direct a flow of liquid entering an input port towards a collection port, such as a cyclonic flow. The baffle may direct the flow of liquid away from a suction port. The baffle may encourage separation of a flow of matter into a liquid flow stream and a gas flow stream.

A baffle may be angled relative to a central vertical axis of the shaft. A baffle may be angled at about 20 degrees, 25 degrees, 30 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees, 60 degrees, 65 degrees, 70 degrees, or about 75 degrees relative to a central vertical axis of the shaft.

A baffle may be positioned along the shaft at a location that is distal to the collection port and adjacent to a suction port. A baffle may be positioned along the shaft at a location that is distal to the collection port and between the suction port and the input port. A baffle may prevent liquids entering the hollow body via the input port from exiting the suction port. A baffle may be a physical barrier to prevent liquids entering the hollow body via the input port from exiting the suction port. A baffle may direct liquids entering the hollow body via the input port to flow towards a collection port.

FIG. 24A-24C shows different views of embodiments of baffles including direction wings or fins on the openings in the baffle. In these embodiments, the wings or fins further block fluid and/or solids in the suction mixture from passing out through the openings in the baffle. The wings or fins are positioned so that they are directly between the direction of flow and the openings in the baffle and shield the openings by both physically blocking liquid and/or solid flow into the openings and redirecting the liquid and/or solid components downwards. In some embodiments the wings or fins have a ramp shape so that they direct the flow of a liquid and/or solid away from the opening in the baffle. The wings or fins are configured to not block gas entry into the openings.

Table 1 is a chart illustrating test results of a separator. The chart illustrates data relating to two different types of suction devices with and without a separator in use. The first type of suction device listed in the chart is a Yankauer suction tip. A Yankauer suction tip is an oral suctioning tool typically comprised of a firm plastic suction tip with a large opening surrounded by a bulbous head and is designed to allow effective suction without damaging surrounding tissues. The second type of suction device (FIRST) listed in the chart is a suction device designed for use in various surgical procedures and may include ports that is variably opened and closed to adjust a ratio of liquids, solids and gasses suctioned by the FIRST device. The term “SLS” refers to the separator disclosed herein.

The test setup included four collection canisters coupled in series, as is used in a common operating room setup. FIG. 12 illustrates an example of two collection canisters 1214, 1234 including two separators 1202, 1222 coupled in series. The canisters were coupled to a CONMED® System 1200™ Smoke Evacuation System (SES). The chart illustrates the time taken to suction 500 cc of 35% glycerol solution at room temperature. In addition, the chart illustrates data pertaining to the suction strength of the two suction devices.

As illustrated in Table 1, the Yankauer device provided strong suction with and without a separator in use. However, suction time decreased from 18 seconds to 11 seconds with the use of a separator system, such as the separator examples described herein. The FIRST device was able to suction 500 cc of 35% glycerol in 133 seconds without the use of a separator. Adding one separator to the system decreased the suction time to 70 seconds. Performance of the FIRST device was improved even further by adding a second separator to the system. The suction time of the FIRST device in conjunction with two separators decreased to 50 seconds. The data shows that the use of a separator, the examples as described herein, may reduce the suction time of various suction times by nearly one-half.
