Description

[0001] Cross Reference to Related Applications

[0002] This application claims priority to and all the benefits of U.S. Provisional Patent Application No. 63 / 483,750, filed February 7, 2023, the entire contents of which are expressly incorporated by reference herein. BACKGROUND

[0003] Various medical devices include filtration systems intended to maintain sterility and / or to capture hazardous particulates. For example, medical devices including vacuum apparatuses can include filtration systems for removing debris and / or hazardous particulates from liquids or air consumed by the vacuum apparatus. Depending on the type of medical device, the filtration system can require large and / or complex filter assemblies to achieve filtration of particulates.

[0004] Similarly, filtration systems can include filter assemblies that include one or more sockets or ports through which a tube of a surgical instrument can be connected. These sockets and ports can be configured to allow debris and / or hazardous particulates to enter the filter assembly. A vacuum or suction can be applied to the filter assembly to draw debris and / or hazardous particulates into the filter assembly through these sockets or ports. The filter assembly can also include a cover or wing intended to cover the sockets or ports when they are not in use and / or when the surgical instrument is not attached. The operation of the filtration system, and more particularly the operation of a vacuum source used to apply a vacuum or suction to the filter assembly, can vary depending on whether the sockets or ports are exposed / uncovered and / or whether an instrument is attached to one or more of the sockets or ports. Conventional filter assemblies do not provide or allow for identification of whether the sockets or ports are exposed or covered and / or whether a surgical instrument is attached to the wing position of the filter assembly. This information can be used to optimize the operation of the filtration system.

[0005] Accordingly, there remains a need in the art for a filter assembly configured to address the various shortcomings of conventional filter assemblies. SUMMARY

[0051] As medical professionals strive to reduce the amount of waste generated by performing various surgical or medical procedures, they seek opportunities to reduce the number of disposable components and increase the number of reusable components. When attempting to identify and design components of a reusable medical device and / or instrument, many factors must be considered. Specifically, the design and / or functionality of the reusable component must allow for sterilization of the environment and the medical device or instrument. One such component that can be used with a medical device and that is traditionally a disposable component is a filter assembly. For example, a filter assembly can be used with a medical waste collection system 100 including a vacuum apparatus, such as a smoke evacuation system, for filtering various particulates, smoke, and / or fluids collected from air during a medical procedure. Traditionally, the entire filter assembly is disposed of after each individual medical procedure is completed. Accordingly, there remains a need in the art for a filter assembly that includes a combination of reusable and disposable components, for example Figure 1 the filter assembly 10 shown.

[0052] Referring to Figure 1 , a perspective view of an example configuration of a filter assembly 10 is shown. Accordingly, the filter assembly 10 can include a housing 12. The housing can also be referred to as a housing, a filter housing, a compartment, etc. The housing 12 can include a plurality of wall members 14A, 14B configured to define an interior 16 Figure 1 of the housing 12 (not shown in FIG. 1). The wall members 14 can be composed of a generally rigid material, such as a plastic polymer or a metal alloy. While the wall members 14 are shown as being generally planar, it is contemplated that the wall members 14 can have other configurations, such as curved or angled configurations. Figure 1The illustrated housing 12 includes four wall members 14A, 14B, 14C, 14D arranged in a square or rectangular configuration, although it is contemplated that the size, shape, and / or number of wall members 14 of the housing 12 can vary. For example, although not illustrated, the housing 12 can include three wall members 14 to define a triangular housing 12. Alternatively, the housing 12 can include a single wall member 14 configured to define a circular or elliptical housing 12.

[0053] The housing 12 can also include a cap 20. The cap 20 can be configured to be removably coupled to the distal end of the housing 12. It is also contemplated that the cap 20 can be integrally formed with the wall members 14A, 14B, 14C, 14D. The cap 20 can include one or more sockets (or sockets) 22. The sockets can also be referred to as openings, apertures, outlets, plugs, connectors, ports, or similar devices that define connection points, for example, as Figure 1 and Figure 2 As illustrated, the cap 20 can include three sockets 22A, 22B, 22C. However, it is contemplated that the cap 20 can be configured to include a single socket 22A, two sockets 22A, 22B, or more sockets. The cap 20 can also define a recess 24A in the outer surface 21 of the cap 20. The design of the cap 20 can be configured such that the recess 24A of the outer surface 21 of the cap 20 can define a protrusion 24B (as illustrated in Figure 4 ) on the inner surface 23 of the cap 20. The recess 24A defined in the outer surface 21 of the cap 20 can be shaped and / or configured as a handle for grasping and / or manipulating the filter assembly 10. For example, the recess 24A can be configured as a handle to allow a user to grasp the filter assembly 10 when removing the filter assembly 10 from the medical waste collection system 100 or a medical device.

[0054] Referring to Figure 3 , an example configuration of a socket cover 26 for use with the cap 20 is shown. The socket cover 26 can include a body 27 configured to be coupled to the outer surface 21 of the cap 20. The body 27 can be removably coupled to the cap 20. Alternatively, the body 27 can be permanently coupled to the cap 20. The body 27 can be formed of a flexible material, such as rubber, or of a generally rigid material, such as plastic. The socket cover 26 can include one or more wings 28 extending from the body 27. For example, as Figure 3As shown, the hole cover 26 includes three wings 28A, 28B, 28C extending from the body 27. The wings 28A, 28B, 28C can be formed of a flexible material, such as a rubber composition. Further, the wings 28A, 28B, 28C can be flexibly or pivotably connected to the body 27. For example, the wings 28A, 28B, 28C can be pivotably connected to the body 27 such that the wings 28A, 28B, 28C can move relative to the body 27 between an open position and a closed position. The body 27 of the hole cover 26 can be coupled to the lid 20 of the housing 12 such that the wings 28A, 28B, 28C are positioned over the respective holes 22A, 22B, 22C of the lid 20. The wings 28A, 28B, 28C can be configured to cover and / or seal the respective jacks 22A, 22B, 22C when in the closed position. The wings 28A, 28B, 28C can also be configured to expose the respective jacks 22A, 22B, 22C when in the open position. Functionally, when the wings 28A, 28B, 28C are in the closed position and cover the respective jacks 22A, 22B, 22C, the wings 28A, 28B, 28C can prevent debris or other particulates from passing through the holes 22A, 22B, 22C of the lid 20. When the filter assembly 10 including the lid 20 having the hole cover 26 is used with the medical waste collection system 100 including a vacuum apparatus, the vacuum apparatus can cause the wings 28A, 28B, 28C to seal against the outer surface of the lid 20 when the wings 28A, 28B, 28C are in the closed position. Alternatively, when the wings 28A, 28B, 28C are in the open position, the filter assembly 10 can be configured such that the vacuum apparatus can draw liquid, gas, and / or other particulates through the jacks 22A, 22B, 22C of the lid 20.

[0055] Referring to Figure 4 , a rear view of the housing 12 of the filter assembly 10 is shown. The proximal end of the housing 12 can define an opening 18 configured to provide access to the interior 16 defined by the wall members 14A, 14B, 14C, 14D. While Figure 4 the opening 18 in the proximal end of the housing 12 shown includes a generally circular shape, it is contemplated that other shapes can be used. For example, the opening 18 can include a triangular shape, a square shape, or other similar polygonal shape.

[0056] The opening 18 in the proximal end of the housing 12 can also define one or more alignment slots 19A, 19B. The alignment slots 19A, 19B can include generally square or rectangular notches in the perimeter of the opening 18. However, it is also contemplated that the alignment slots 19A, 19B can include semi-spherical concave shapes, triangular, or other polygonal notches. For example, as Figure 4As shown, the opening 18 includes a first alignment slot 19A and a second alignment slot 19B. The first alignment slot 19A includes a generally rectangular shape having a first dimension, and the second alignment slot 19B includes a generally rectangular shape having a second dimension, where the first dimension and the second dimension are different from one another. As Figure 4 As shown, the exemplary configuration of the opening 18 includes a first alignment slot 19A having a first dimension and a second alignment slot 19B having a second dimension, where the first dimension is less than the second dimension. Alternatively, although not shown in the figures, it is also contemplated that the alignment slots 19A, 19B can be configured as alignment tabs that protrude from the perimeter of the opening 18. For example, the alignment tabs can include a hemi-spherical convex shape, a triangular shape, or a similar polygonal shape that extends from the perimeter of the opening 18. Further, although the figures only show the alignment slots 19A, 19B cut out from the perimeter of the opening 18 in the proximal panel 17 of the housing 12, it is contemplated that the interior 16 defined by the wall members 14A, 14B, 14C, 14D can include the same shape as the opening 18. For example, the interior 16 defined by the wall members 14A, 14B, 14C, 14D can include a cylindrical shape that extends from the proximal end to the proximal end of the housing 12, where the interior surface of the cylinder can define one or more alignment slots 19A, 19B that extend the length of the cylinder. Although Figure 4 The alignment slots 19A, 19B shown in FIGS. 1-3 generally bisect the opening 18, but other arrangements and / or orientations are contemplated. For example, visualizing the opening 18 as a clock face, it is contemplated that the first alignment slot 19A can be positioned at approximately eleven o’clock (as shown in FIG. 1), and the second alignment slot 19B can be positioned at approximately one o’clock. In yet another configuration, the first alignment slot 19A can be positioned at approximately one o’clock, and the second alignment slot 19B can be positioned at approximately five o’clock (as shown in FIG. 2). In yet another configuration, the first alignment slot 19A can be positioned at approximately five o’clock, and the second alignment slot 19B can be positioned at approximately eleven o’clock (as shown in FIG. 3). Figure 4 As shown, the exemplary configuration of the opening 18 includes a first alignment slot 19A having a first dimension and a second alignment slot 19B having a second dimension, where the first dimension is less than the second dimension. Alternatively, although not shown in the figures, it is also contemplated that the alignment slots 19A, 19B can be configured as alignment tabs that protrude from the perimeter of the opening 18. For example, the alignment tabs can include a hemi-spherical convex shape, a triangular shape, or a similar polygonal shape that extends from the perimeter of the opening 18. Further, although the figures only show the alignment slots 19A, 19B cut out from the perimeter of the opening 18 in the proximal panel 17 of the housing 12, it is contemplated that the interior 16 defined by the wall members 14A, 14B, 14C, 14D can include the same shape as the opening 18. For example, the interior 16 defined by the wall members 14A, 14B, 14C, 14D can include a cylindrical shape that extends from the proximal end to the proximal end of the housing 12, where the interior surface of the cylinder can define one or more alignment slots 19A, 19B that extend the length of the cylinder. Although Figure 4 As shown, the exemplary configuration of the opening 18 includes a first alignment slot 19A having a first dimension and a second alignment slot 19B having a second dimension, where the first dimension is less than the second dimension. Alternatively, although not shown in the figures, it is also contemplated that the alignment slots 19A, 19B can be configured as alignment tabs that protrude from the perimeter of the opening 18. For example, the alignment tabs can include a hemi-spherical convex shape, a triangular shape, or a similar polygonal shape that extends from the perimeter of the opening 18. Further, although the figures only show the alignment slots 19A, 19B cut out from the perimeter of the opening 18 in the proximal panel 17 of the housing 12, it is contemplated that the interior 16 defined by the wall members 14A, 14B, 14C, 14D can include the same shape as the opening 18. For example, the interior 16 defined by the wall members 14A, 14B, 14C, 14D can include a cylindrical shape that extends from the proximal end to the proximal end of the housing 12, where the interior surface of the cylinder can define one or more alignment slots 19A, 19B that extend the length of the cylinder. Although

[0057] The filter assembly 10 can also include a particulate sensor 30 disposed within the interior 16 of the housing 12. The particulate sensor 30 can include an optical sensor, a chemical sensor, or a laser sensor. For example, an optical particulate sensor 30 can include an infrared emitting diode (IRED) and a phototransistor arranged diagonally such that the optical particulate sensor 30 can detect reflected light of dust in the air. This type of optical particulate sensor 30 can be generally effective at detecting very fine particles, such as cigarette smoke. The particulate sensor 30 can include a sensor housing 31 and a sensor element 33. As Figure 4As shown, the sensor housing 31 and, by extension, the sensor 30 can be coupled to or mounted on the lid 20 of the housing 12. Although not shown in the figures, it is further contemplated that the particulate sensor 30 can be mounted at other locations within the interior 16 of the housing 12. For example, the particulate sensor 30 can be mounted to the first wall member 14A. Alternatively, the particulate sensor 30 can be mounted to the second wall member 14B. The sensor element 33 can include operational features of the sensor, such as a light bulb of an optical sensor configured to visually detect the presence of various particulates. Alternatively, the sensor element 33 can include a chemical analyzer configured to detect the presence of various particulates. The sensor wire 34 extends from the sensor housing 31 of the particulate sensor 30. The sensor wire 34 can include a sensor tab 36 coupled to the sensor wire 34 opposite the sensor 30. The sensor tab 36 can be configured to couple to a complementary tab on the medical waste collection system 100 or a medical device to connect the particulate sensor 30 to a controller 102 of the system 100 or device.

[0058] The filter assembly 10 can further include a seal member 32 disposed within the interior 16 of the housing 12. The seal member 32 can be coupled to the lid 20 and positioned to at least partially surround the sensor 30. A portion of the seal member 32 can also at least partially encircle a length of the sensor wire 34 to form a seal between the sensor wire 34 and the lid 20 of the housing 12.

[0059] Referring to Figure 5A , 5B and 5C, an exemplary configuration of a filter cartridge 38 of the filter assembly 10 is shown. The filter cartridge 38 can be configured to be removably disposed within the interior 16 of the housing 12. The filter cartridge 38 can include a cartridge housing 40 configured to define an outer perimeter of the filter cartridge 38. As Figure 5A shown, the cartridge housing 40 can include a generally cylindrical shape. However, it is also contemplated that the cartridge housing 40 and, by extension, the filter cartridge 38 can be configured to alternative shapes. For example, the cartridge housing 40 can be configured as a square cuboid, a rectangular cuboid, or similar three-dimensional shape. The shape of the filter housing 40 and, by extension, the shape of the filter cartridge 38 can generally be configured to allow the filter cartridge 38 to be inserted through the opening 18 in the proximal end of the housing 12.

[0060] The filter cartridge 38 can also be coated with a liquid-impermeable coating 41 configured to prevent liquid from entering the filter cartridge 38. The liquid-impermeable coating 67 can be disposed on one of the exterior or interior surfaces of the filter cartridge 38, such as the interior or exterior surface of the filter cartridge housing 40. It is also contemplated that the liquid-impermeable coating 67 can be disposed on both the exterior and interior surfaces of the filter cartridge 38, such as the interior and exterior surfaces of the cartridge housing 40. The liquid-impermeable coating 41 can be configured to prevent liquid from entering the filter cartridge 38 and potentially damaging the internal components of the filter cartridge 38, such as the filter portion 66, which will be discussed in more detail below. It is also contemplated that the liquid-impermeable coating 41 can also prevent liquid from leaking through or exiting the filter cartridge 38. For example, preventing liquid from leaking through the filter cartridge 38 and potentially contaminating the interior 16 of the housing 12.

[0061] It is also contemplated that at least one of the interior of the smoke evacuation tube 110 and / or the interior chamber of the filter cartridge 38 can include an absorbent material configured to prevent damage to the filter cartridge 38 and / or the internal components of the filter cartridge 38. For example, the absorbent material can be an aqueous superabsorbent coating (ASC) technology, which is a liquid polymer solution that is dried to form an absorbent film. ASC can be applied to a range of materials and substrates using various techniques to absorb condensed or evaporated fluids. ASC is delivered as a liquid suspension that self-crosslinks upon drying to form a superabsorbent film coating that can absorb many times its own weight in water. Water vapor, bodily fluids, and other aqueous solutions can also be absorbed by the coating.

[0062] The filter cartridge 38 can also include one or more alignment features 64A, 64B positioned on the exterior of the cartridge housing 40. As shown, Figure 5A The alignment features 64A, 64B can be configured as rails, tabs, or protrusions that extend from the exterior of the cartridge housing 40. The alignment features 64A, 64B can be positioned on the exterior of the cartridge housing 40 to align and / or orient the filter cartridge 38 within the housing 12. For example, as shown, Figure 5AAs shown, the alignment features 64A, 64B can include rails that extend the length of the filter cartridge 38. Alternatively, the alignment features 64A, 64B can include protrusions or tabs positioned at a point along the filter cartridge 38. For example, the alignment features 64A, 64B can include protrusions positioned at the distal end of the filter cartridge 38. The alignment features 64A, 64B can be configured to be at least partially disposed within complementary alignment slots 19A, 19B defined in the opening 18 of the housing 12 when the filter cartridge 38 is disposed in the housing 12. For example, the first alignment feature 64A can be aligned with and at least partially disposed within the first alignment slot 19A in the opening 18, and the second alignment feature 64B can be aligned with and at least partially disposed within the second alignment slot 19B in the opening 18. Alternatively, as described above, when the opening 18 includes alignment tabs, the cartridge shell 40 can be configured to include alignment grooves configured to at least partially receive the alignment tabs of the opening 18 to align and / or orient the filter cartridge 38 within the housing 12.

[0063] The filter cartridge 38 can also include a back plate 42 and a face plate 44 coupled to opposite ends of the cartridge shell 40. The back plate 42 can be positioned at the proximal end of the filter cartridge 38, and the face plate 44 can be positioned at the distal end of the filter cartridge 38. The back plate 42 and the face plate 44 can be coupled to the cartridge shell 40 to define an interior chamber 45 of the filter cartridge 38.

[0064] The face plate 44 of the filter cartridge 38 can include an outer surface 46 and an opposite inner surface 48, with a rim 54 surrounding an outer periphery of the face plate 44. The outer surface 46 can include a first portion 50 and a second portion 52, with the second portion 52 positioned proximally of the first portion 50 to define a recess in the outer surface 46. The recess defined by the second portion 52 of the outer surface 46 can be configured to receive the protrusion 24B on the inner surface 23 of the lid 20 when the filter cartridge 38 is disposed within the interior 16 of the housing 12.

[0065] The rim 54 surrounding the outer periphery of the face plate 44 can protrude distally from the outer surface 46. The rim 54 can also protrude proximally from the inner surface 48 of the face plate 44. The rim 54 can also include one or more coupling members 62A, 62B configured to removably couple the filter cartridge 38 to the housing 12 when disposed within the interior 16. As Figure 5AAs shown, connecting members 62A, 62B may include tabs forming part of the edge portion 54 and positioned on opposite sides of the panel 44. However, it is also contemplated that connecting members 62A, 62B may be positioned at alternative locations on the panel 44 and / or the filter element 38. For example, connecting members 62A, 62B may be coupled to or formed as part of the filter element housing 40. As will be described in more detail below, the wall members 14A, 14B, 14C, 14D of the housing 12 may include complementary connecting features 15A, 15B, such as notches or openings, configured to engage the connecting members 62A, 62B of the filter element 38 (see Figure 8 ).

[0066] The panel 44 of the filter element 38 may also include one or more openings defining ports 56A, 56B, 56C in the panel 44. For example... Figure 5A As shown, panel 44 may include three ports 56A, 56B, 56C, which may be arranged in a generally linear configuration and positioned on a first portion 50 of the outer surface 46 of panel 44. However, other configurations and arrangements of ports 56A, 56B, 56C are contemplated. For example, panel 44 may include only a single port 56A, or it may include two ports 56A, 56B. It is also contemplated that panel 44 may include more than three ports 56A, 56B, 56C…56n. Although not shown in the figures, it is also contemplated that ports 56A, 56B, 56C may be positioned at alternative locations on the outer surface 46 of panel 44, such as an open space on panel 44 above the first port 56A. Each of ports 56A, 56B, 56C may be configured to receive an end or portion of a tube 110 (such as a smoke exhaust tube) used as part of medical waste collection system 100 or a medical device. This end may include a smoke exhaust pipe connector or fitting configured to be removably connected to ports 56A, 56B, 56C of panel 44.

[0067] Each of the ports 56A, 56B, 56C can also include a valve 57A, 57B, 57C disposed within the opening defining the port 56A, 56B, 56C. The valve 57A, 57B, 57C can be configured to control the flow of fluid and / or gas into and out of the filter cartridge 38. For example, the valve 57A, 57B, 57C can include a one-way valve that only allows fluid and / or gas to flow into the filter cartridge 38. Alternatively, the valve 57A, 57B, 57C can include a two-way valve that allows fluid and / or gas to flow into and out of the filter cartridge 38. One example of a one-way fluid valve for use with the filter cartridge 38 is a rubber-sealed valve, such as a wing valve, umbrella valve, and / or duckbill valve. The one-way rubber-sealed valve can be disposed within the port 56A, 56B, 56C and can be configured such that when an end or portion of the pipe 110, such as a vent pipe, is coupled to the port 56A, 56B, 56C, the valve 57A, 57B, 57C opens to allow fluid and / or gas to flow into the filter cartridge 38. Then, when the pipe 110 is removed from the port 56A, 56B, 56C, the valve 57A, 57B, 57C can close to prevent fluid and / or gas from flowing out of the filter cartridge 38.

[0068] Each of the ports 56A, 56B, 56C can also include an annular boss 58A, 58B, 58C that surrounds one of the ports 56A, 56B, 56C and protrudes distally from the outer surface 46 of the faceplate 44. The annular boss 58A, 58B, 58C can be configured to couple an end of the pipe 110 to the faceplate 44. Each of the ports 56A, 56B, 56C, and by extension, each of the corresponding annular bosses 58A, 58B, 58C, can include an opening of a different size to allow different sized pipes 110 to be coupled to the faceplate 44. For example, each of the annular bosses 58A, 58B, 58C can be sized and configured to receive a pipe 110 wherein the annular boss 58A, 58B, 58C creates a friction fit with the pipe 110 to couple the pipe 110 to the faceplate 44. Alternatively, the annular boss 58A, 58B, 58C can include a joint or coupling feature, such as a notch or indentation, and the pipe 110 can include a complementary joint comprising a tab or protrusion configured to engage the coupling feature of the annular boss 58A, 58B, 58C to removably couple the joint of the pipe 110 to the faceplate 44.

[0069] Further, each of the annular bosses 58A, 58B, 58C can include a distal end 59A, 59B, 59C. The distal end 59A, 59B, 59C of the annular boss 58A, 58B, 58C can be sized to fit or fit within one of the complementary sockets 22A, 22B, 22C of the cover 20 when the filter cartridge 38 is disposed within the interior 16 of the housing 12.

[0070] The faceplate 44 of the filter cartridge 38 can also include a sensor opening 60. The sensor opening 60 can be positioned on the faceplate 44 such that the sensor opening 60 receives at least a portion of the particulate sensor 30 when the filter cartridge 38 is disposed within the interior 16 of the housing 12. For example, the sensor opening 60 on the faceplate 44 is configured to receive the particulate sensor 30 such that the particulate sensor 30 is at least partially disposed within the interior chamber 45 of the filter cartridge 38 when disposed within the housing 12. The particulate sensor 30 can be oriented such that the sensor element 33 can be pointed toward the ports 56A, 56B, 56C of the faceplate 44 when the particulate sensor 30 is at least partially disposed within the interior chamber 45 of the filter cartridge 38. This can improve the ability of the particulate sensor 30 to detect the presence of particulates entering the cartridge through the ports 56A, 56B, 56C of the faceplate 44. Further, the sealing member 32 surrounding at least a portion of the particulate sensor 30 can be configured to provide a seal between the outer surface 46 of the faceplate 44 and the inner surface 23 of the cover 20 surrounding the sensor opening 60 when the filter cartridge 38 is disposed within the housing 12 to prevent liquid, gas, or other particulates from exiting the interior chamber 45 of the filter cartridge 38 through the sensor opening 60. While the sealing member 32 was previously described as being coupled to the cover 20, it is also contemplated that the sealing member 32 can be coupled to the outer surface 46 of the faceplate 44.

[0071] The arrangement and position of various features of the filter cartridge 38, and more particularly the faceplate 44, can facilitate orienting the filter cartridge 38 within the housing 12. As described above, the position of the alignment slots 19A, 19B and the alignment features 64A, 64B of the housing 12 can be complementarily arranged to align the ports 56A, 56B, 56C of the faceplate 44 with the apertures 26A, 26B, 26C of the cover 20 when the filter cartridge 38 is disposed within the housing 12. The position of the alignment slots 19A, 19B of the housing 12 can similarly orient the sensor opening 60 with respect to the sensor 30 such that the particulate sensor 30 can be at least partially disposed within the sensor opening 60 when the filter cartridge 38 is disposed within the housing 12. For example, as described above, the first alignment slot 19A can be positioned at approximately eleven o’clock and the second alignment slot 19B can be positioned at approximately five o’clock. The complementary alignment features 64A, 64B can be positioned at the same positions on the filter cartridge 38. The particulate sensor 30 can then be positioned at approximately twelve o’clock on the cover 20 and the sensor opening 60 can similarly be positioned at approximately twelve o’clock. This arrangement of complementary features allows the particulate sensor 30 to be at least partially disposed within the sensor opening 60 when the filter cartridge 38 is disposed within the housing 12.

[0072] The positions of the alignment features 64A, 64B of the filter cartridge 38 can be complementarily arranged relative to the positions of the annular bosses 58A, 58B, 58C of the faceplate 44 such that the annular bosses 58A, 58B, 58C are disposed within the apertures 26A, 26B, 26C of the cover 20 when the filter cartridge 38 is disposed within the housing 12. For example, as described above, the first alignment feature 64A can be positioned at approximately eleven o’clock and the second alignment feature 64B can be positioned at approximately five o’clock. The annular bosses 58A, 58B, 58C can be arranged in a generally linear configuration along an axis extending between three o’clock and nine o’clock. The complementary apertures 26A, 26B, 26C in the cover 20 can be similarly arranged such that the annular bosses 58A, 58B, 58C are disposed within the apertures 26A, 26B, 26C of the cover 20 when the filter cartridge 38 is disposed within the housing 12. The combination of these various complementary features ensures that the filter cartridge 38 is inserted into the housing 12 in a single orientation such that the particulate sensor 30 can be disposed within the sensor opening 60 and the annular bosses 58A, 58B, 58C can be disposed within the apertures 26A, 26B, 26C when the filter cartridge 38 is disposed within the housing 12. Although not described in detail, other configurations or arrangements of the ports 56A, 56B, 56C relative to the apertures 26A, 26B, 26C and the sensor opening 60 relative to the particulate sensor 30 are contemplated.

[0073] REFERENCE Figure 5BA cross-sectional view of filter element 38 is shown to illustrate the various internal components of filter element 38. Filter element 38 of filter assembly 10 may also include a filter portion 66 disposed within an internal chamber 45 defined by filter element housing 40. The filter portion 66 of filter element 38 may include one or more filter layers 68A, 68B, 68C, 68D, 68E. Each of filter layers 68A, 68B, 68C, 68D, 68E may include different materials and / or pore sizes, configured to collect particles of different sizes and / or types when liquids or gases pass through the respective filter layers 68A, 68B, 68C, 68D, 68E. For example, one or more of filter layers 68A, 68B, 68C, 68D, 68E may include fibrous or porous materials that remove solid particles, such as dust, pollen, mold, and bacteria, from the air. Alternatively, one or more of filter layers 68A, 68B, 68C, 68D, and 68E may include an adsorbent or catalyst, such as charcoal (carbon), which may also remove odors and / or gaseous contaminants, such as volatile organic compounds or ozone. For example, the first filter layer 68A may include a thick, sloping foam of meltblown plastic material configured to capture larger particles in front of the ULPA filter media. The second filter layer 68B may include a ULPA pleated package comprising a filter media having approximately 40 pleats and a depth of 1.5 inches. It may be used with a cardboard tube and bonded using spin glue technology. The other layers 68C, 68D, and 68E of the filter section 66 may include activated carbon, for example, using activated carbon foam with an inner diameter of 5.0 inches and bonded to a cardboard tube.

[0074] refer to Figure 6 The diagram shows a perspective view of the inner surface 48 of panel 44. The panel 44 of filter cartridge 38 may also include one or more supports 61A, 61B, 61C positioned on and projecting distally from the inner surface 48 of panel 44. Each of the supports 61A, 61B, 61C may be configured to at least partially surround ports 56A, 56B, 56C of panel 44. The supports 61A, 61B, 61C may be configured to prevent over-insertion of tube 110 connected to panel 44 via ports 56A, 56B, 56C and / or annular bosses 58A, 58B, 58C. For example, tube 110 may slide into annular bosses 58A, 58B, 58C and through ports 56A, 56B, 56C in panel 44. Brackets 61A, 61B, and 61C can be positioned on the inner surface 48 of panel 44 and are configured to stop the insertion of tube 110 once tube 110 passes through panel 44.

[0075] refer to Figure 7 The filter element 38 is shown, but the filter housing 40 is not shown. Although in Figure 7The housing 12 is not shown, but the particulate sensor 30 is shown as being within the interior chamber 45 of the filter cartridge 38 as if the filter cartridge 38 were disposed within the housing 12. As can be seen in Figure 7 the filter portion 66 of the filter cartridge 38 can be spaced apart from the faceplate 44, and more particularly, from the interior surface 48 of the faceplate 44 (not visible in Figure 7 ). The filter portion 66 can be spaced apart from the interior surface 48 of the faceplate 44 to define a void space 70 within the interior chamber 45 of the filter cartridge 38. The ports 56A, 56B, 56C and the sensor opening 60 can be in fluid communication with the void space 70. The void space 70 can be configured to receive smoke, liquid, gas, or other particulate collected via the tubes 110 coupled to the ports 56A, 56B, 56C of the faceplate 44. The void space 70 can be configured to receive at least a portion of the particulate sensor 30 via the sensor opening 60 such that at least a portion of the particulate sensor 30 is disposed within the void space 70 when the filter cartridge 38 is disposed within the housing 12. The particulate sensor 30 can be configured to detect the presence of smoke, liquid, gas, or other particulate entering the filter cartridge 38 via the ports 56A, 56B, 56C. For example, as described above, the particulate sensor 30 can include an optical sensor configured to detect the presence of smoke within the void space 70. Alternatively, it is further contemplated that the particulate sensor 30 can include a chemical sensor configured to detect the presence of a gas or particulate other than oxygen within the void space 70.

[0076] Referring to Figure 8 and Figure 9 , different views of the filter cartridge 38 disposed within the housing 12 are shown. Figure 8 A perspective view of the filter cartridge 38 disposed within the housing 12 is provided. The lid 20 of the housing 12 is omitted to illustrate the positioning and relationship of the filter cartridge 38 and the housing 12. In particular, as can be seen in Figure 8 , the particulate sensor 30 can be inserted through the sensor opening 60 such that the particulate sensor 30 can be at least partially disposed within the filter cartridge 38. Further, an exemplary configuration of the coupling members 62A, 62B of the filter cartridge 38 and the complementary coupling features 15A, 15B of the wall members 14A, 14B, 14C, 14D of the housing 12 are shown. For example, the coupling members 62A, 62B of the filter cartridge 38 can include tabs configured to engage the complementary coupling features 15A, 15B including notches in the wall members 14A, 14C. The coupling members 62A, 62B can snap into the complementary coupling features 15A, 15B when the filter cartridge 38 is inserted into the housing 12. Alternatively, the coupling members 62A, 62B can be manipulated or depressed to disengage from the complementary coupling features 15A, 15B in order to remove the filter cartridge 38 from the housing 12.

[0077] Figure 9 A cross-sectional view of the filter assembly 10 including the filter cartridge 38 disposed within the housing 12 is provided. Specifically, Figure 9 An exemplary configuration of the filter assembly 10 in which the filter cartridge 38 is disposed within the housing 12 is shown, as well as how the faceplate 44 interacts with the lid 20 of the housing 12. For example, as shown, Figure 9 The annular bosses 58A, 58B, 58C of the faceplate 44 can be at least partially disposed within the sockets 22A, 22B, 22C of the lid 20, as shown. It is contemplated that the distal ends 59A, 59B, 59C of the annular bosses 58A, 58B, 58C can be positioned such that they are flush with the outer surface 21 of the lid 20 when the filter cartridge 38 is disposed within the interior 16 of the housing 12. Alternatively, it is also contemplated that the distal ends 59A, 59B, 59C of the annular bosses 58A, 58B, 58C can be positioned such that they are distal to and / or extend beyond the outer surface 21 of the lid 20 when the filter cartridge 38 is disposed within the interior 16 of the housing 12. Positioning the distal ends 59A, 59B, 59C of the annular bosses 58A, 58B, 58C to be flush with or distal to the outer surface 21 of the lid 20 allows the smoke evacuation tube 110 to be directly coupled to the filter cartridge 38. This greatly reduces the likelihood that any particulate collected by the smoke evacuation tube 110 will end up within the filter cartridge 38 rather than the housing 12. This reduces the likelihood that the housing 12 will be contaminated between medical procedures and / or that the housing 12 will need to be sterilized. Further, it is contemplated that the distal ends 59A, 59B, 59C of the annular bosses 58A, 58B, 58C can be positioned such that they are proximal to the outer surface 21 of the lid 20 when the filter cartridge 38 is disposed within the interior 16 of the housing 12. While this configuration can still allow the smoke evacuation tube 110 to be directly coupled to the filter cartridge 38, this can not be as desirable for the smoke evacuation tube 110 to be coupled to the ports 56A, 56B, 56C, which can be more likely to result in contamination of the housing 12.

[0078] Figure 9 An exemplary configuration of the filter assembly 10 is also shown in which the protrusion 24B on the inner surface 23 of the lid 20 is at least partially disposed within the recess defined by the first portion 50 and the second portion 52 of the faceplate 44. For example, as shown, Figure 9 When the filter cartridge 38 is disposed within the interior 16 of the housing 12, the protrusion 24B on the inner surface 23 of the lid 20 defined by the recess in the outer surface 21 of the lid 20 is positioned adjacent to the second portion 52 of the faceplate 44, as shown.

[0079] While not shown in FIG. 1, Figure 9The cover 20 can include a plurality of flaps 28A, 28B, 28C coupled to the body 27 of the cover 26. The flaps 28A, 28B, 28C can be coupled to the body 27 of the cover 26 in any suitable manner, such as by a hinge, as shown in FIG. 3, but it should be understood that the flaps 28A, 28B, 28C can be coupled to the outer surface 21 of the cover 20. As described above, the flaps 28A, 28B, 28C can be pivotably connected to the body 27 of the cover 26 such that the flaps 28A, 28B, 28C can move between an open position and a closed position relative to the body 27. The flaps 28A, 28B, 28C can be configured to cover and / or seal the respective jacks 22A, 22B, 22C and / or ports 56A, 56B, 56C when in the closed position. The flaps 28A, 28B, 28C can also be configured to expose the respective jacks 22A, 22B, 22C and / or ports 56A, 56B, 56C when in the open position.

[0080] In operation, the filter assembly 10, including the filter cartridge 38 disposed in the housing 12, can be installed in or coupled to the medical waste collection system 100. This process will be described in greater detail below. Once the filter assembly 10 is installed within the medical waste collection system 100, a tube 110, such as a smoke tube, can be coupled to the filter assembly 10 by coupling a fitting of the tube 110 to one of the ports 56A, 56B, 56C and / or annular bosses 58A, 58B, 58C of the filter cartridge 38. A vacuum can then be applied to the proximal end of the filter cartridge 38 by a vacuum source of the medical waste collection system 100. By way of example, when the filter assembly 10 is installed in the medical waste collection system 100, the back plate 42 of the filter cartridge 38 can be coupled to a vacuum source of the medical waste collection system 100 that is configured to draw a vacuum through the filter cartridge 38. The vacuum applied to the filter cartridge 38 can cause a vacuum to be drawn through the tube 110 connected to any of the ports 56A, 56B, 56C and / or annular bosses 58A, 58B, 58C of the filter cartridge 38. Particulates will be collected via the tube 110 and deposited in the filter cartridge 38. The particulates can include fluids, smoke, or other gases. Initially, the particulates will accumulate in the interstitial space 70 between the filter portion 66 and the inner surface 48 of the face plate 44, and then be drawn toward the filter portion 66. The particulate sensor 30 can be positioned within the interstitial space 70 and configured to detect the presence of particulates in the interstitial space 70. The particulate sensor 30 can then send a signal to the controller 102 of the medical waste collection system 100. The controller 102 of the medical waste collection system 100 can be configured to adjust the settings of the vacuum source based at least in part on the signal received from the sensor 30. For example, when the particulate sensor 30 does not detect particulates within the interstitial space 70, the controller 102 can be configured to operate the vacuum device at a lower power setting. Alternatively, when the particulate sensor 30 detects particulates within the interstitial space 70, the controller 102 can be configured to operate the vacuum device at a higher power setting to help draw the particulates into and through the filter cartridge 38. Then, as various particulates are pulled (or drawn) through the filter portion 66 by the vacuum device, the various filter layers 68A, 68B, 68C, 68D, 68E of the filter portion 66 can filter out these particulates.

[0081] Reference is made to Figures 10 to 11B various partial exploded views of an example configuration of the filter assembly 10. These partial exploded views help illustrate various steps of a method of replacing the filter assembly 10. Specifically, Figure 10 and 11A illustrate various steps in the method of replacing the filter assembly 10 that are related to removing and installing the filter cartridge 38 / 38A. Figure 11BA filter assembly 10 including an alternative filter cartridge 38B is shown. While Figure 10 and Figure 11A The filter cartridge 38 / 38A shown includes a generally cylindrical shape, but as Figure 11B shown, it is also contemplated that the filter cartridge 38B can include a generally square cuboid, a rectangular cuboid, or similar three-dimensional shape, as described above. The opening 18 in the housing 12, as well as the slots 19A, 19B, can be modified to accommodate and / or receive the filter cartridge 38, 38A, 38B. This is true for any configuration of the filter cartridge 38, 38A, 38B of the filter assembly 10 described above or below.

[0082] Referring to Figure 12 , a partial exploded view of an exemplary configuration of a medical waste collection system 100 including the filter assembly 10 described above is shown. The medical waste collection system 100 can include a main body component (H) configured to receive the filter assembly 10. The main body component can also be referred to as a console, cart, station, receiver, or the like. The main body component (H) can define an opening or receiver 108 for receiving the filter assembly 10.

[0083] The partial exploded view helps illustrate the various steps of a method of replacing the filter assembly 10 of the medical waste collection system 100.

[0084] The method of replacing the filter assembly 10 of the medical waste collection system 100

[0085] An exemplary method of replacing the filter cartridge 38 of the filter assembly 10 for use with the medical waste collection system 100 is described below. As described above, the filter assembly 10 can include a housing 12 defining an interior 16, an opening 18 in the housing 12, and slots 19A, 19B. The enclosure can also include a front cover 20 having sockets 22A, 22B, 22C, and a particulate sensor 30 disposed within the housing 12. The method of replacing the filter cartridge 38 of the filter assembly 10 can include the step of providing the filter cartridge 38. The filter cartridge 38 can include a faceplate 44 having ports 56A, 56B, 56C to removably couple the exhaust pipe 110 fitting to the faceplate 44, alignment features 64A, 64B coupled to an exterior of the filter cartridge 38, and a sensor opening 60 in the faceplate 44. It is contemplated that the filter cartridge 38 can include any combination of the features described above.

[0086] The method can further include a step of orienting the filter cartridge 38 such that the alignment features 64A, 64B of the filter cartridge 38 can be inserted into the slots 19A, 19B of the housing 12 prior to the filter cartridge 38 being slid through the opening 18. For example, as shown by the arrow in FIG. 11, the filter cartridge 38 can be rotated such that the alignment features 64A, 64B of the filter cartridge 38 are positioned to be inserted into the slots 19A, 19B of the housing 12.

[0087] Once the alignment features 64A, 64B of the filter cartridge 38 have been aligned with the slots 19A, 19B of the housing 12, the method can include a step of installing the filter cartridge 38 within the housing 12 by sliding the filter cartridge 38 through the opening 18 to place the alignment features 64A, 64B within the slots 19A, 19B. For example, as shown by the arrow in FIG. 11, by sliding the filter cartridge 38 through the opening 18 in the housing 12 and positioning the filter cartridge 38 within the interior of the housing 12, the filter cartridge 38 can be moved distally relative to the housing 12. This should at least partially position the particulate sensor 30 within the sensor opening 60 of the filter cartridge 38 and at least partially position the ports 56A, 56B, 56C of the filter cartridge 38 within the apertures 22A, 22B, 22C in the cap 20.

[0088] The method can also include a step of installing the filter assembly 10 within the opening or receptacle 108 of the medical waste collection system 100. The step of installing the filter assembly 10 can also include connecting the particulate sensor 30 to the medical waste collection system 100. For example, the filter assembly 10 can be installed in the medical waste collection system 100 by inserting the filter assembly 10 into the receptacle 108. When the filter assembly 10 is inserted into the receptacle 108, the sensor tab 36 can be coupled to a complementary tab on the medical waste collection system 100 to connect the particulate sensor 30 to the controller 102 of the system 100.

[0089] The method can further include the steps of removing the filter assembly 10 from the medical waste collection system 100 and removing the filter cartridge 38 from the interior 16 of the original housing 12. Once the previous filter cartridge 38 has been removed, the method can further include orienting a subsequent filter cartridge 38B such that the alignment features 64A, 64B of the subsequent filter cartridge 38B can be inserted within the grooves in at least one of the wall members 14A, 14B, 14C, 14D. The subsequent filter cartridge 38B can then be installed within the original housing 12 by sliding the subsequent filter cartridge 38B through the opening 18 with the alignment features 64A, 64B placed within the slots 19A, 19B, with the particulate sensor 30 at least partially disposed within the sensor opening 60 of the subsequent filter cartridge 38B, and with the ports 56A, 56B, 56C of the subsequent filter cartridge 38B aligned with the apertures 22A, 22B, 22C in the cover 20. The filter assembly 10 including the subsequent filter cartridge 38B can then be installed within the medical waste collection system 100. The housing 12 including the cover 20 can be configured to be reusable for multiple procedures. For example, the housing 12 and cover 20 can be reused for three medical procedures, four medical procedures (or surgeries), or more. In the example configuration of the housing 12 and cover 20, it is contemplated that the housing 12 and cover 20 can be reused for four separate medical procedures. However, it can be advantageous to replace the filter cartridge 38 after each individual medical procedure. Thus, after each medical procedure, the filter cartridge 38 can be removed from the housing 12 and replaced with a new filter cartridge 38B.

[0090] The method can further include repeating the steps of removing the filter assembly 10 from the medical waste collection system 100, removing the filter cartridge 38, orienting a subsequent filter cartridge 38B, installing the subsequent filter cartridge 38B, and installing the filter assembly 10 within the medical waste collection system 100.

[0091] The method can further include the step of counting each occurrence of installing a subsequent filter cartridge within the enclosure to indicate a number of uses of the filter assembly 10. This can be accomplished by including a transceiver or identification tag 72, 74, such as an RFID tag, on each of the housing 12 and the filter cartridge 38 (see FIG. 1). The identification tag 72, 74 can be read by a reader 76, 78 when the filter cartridge 38 is installed within the housing 12. The reader 76, 78 can be located on the medical waste collection system 100 or on a separate device. The reader 76, 78 can be configured to count each occurrence of installing a filter cartridge 38 within the housing 12. The reader 76, 78 can be configured to communicate the number of uses of the filter assembly 10 to a display 80, 82 on the medical waste collection system 100 or on a separate device. Figure 10and FIG. 11). Each of the transceivers 72, 74 can include memory that can include one or more pieces of datum related to the housing 12 and / or filter cartridge 38. For example, the transceivers 72, 74 can identify the particular type and / or various features of the housing 12 and / or filter cartridge 38. This can include a particular serial number or identification number associated with each of the housing 12 and / or filter cartridge 38. The memory of the transceivers 72, 74 can also include the pore size and / or filtration rating of the filter cartridge 38. The transceivers 72, 74 can also identify the type of housing 12 and filter cartridge 38 in order to confirm that a compatible filter cartridge 38 is installed in the housing 12, and by extension, that a compatible housing 12 and / or filter cartridge 38 is installed in the medical waste collection system 100. The medical waste collection system 100 can include a reader 106 or antenna coupled to the controller 102, where the reader 106 is configured to read the transceivers 72, 74 of the housing 12 and / or filter cartridge 38 and transmit the data received from the transceivers 72, 74 to the controller 102 of the medical waste collection system 100. The transceivers 72, 74 can be read by the reader 106 or antenna of the medical waste collection system 100 and the data can be transmitted to the controller 102. The controller 102 can be configured to use the serial number of the housing 12 and / or filter cartridge 38 to determine whether the housing 12 and / or filter cartridge 38 has previously been installed in the medical waste collection system 100. The controller 102 can also confirm that the housing 12 and / or filter cartridge 38 is compatible with the medical waste collection system 100. The controller 102 can then be configured to operate the medical waste collection system 100 based on the data received from the transceivers 72, 74. For example, the controller 102 can be configured to prevent operation of the medical waste collection system 100 if the controller 102 identifies that either of the housing 12 and / or filter cartridge 38 has exceeded a threshold number of uses or is not compatible with the medical waste collection system 100. The controller 102 can also be configured to adjust the vacuum source of the medical waste collection system 100 based on the type and / or pore size of the filter cartridge 38 installed.

[0092] Alternatively, the filter assembly 10 can include a mechanical counter attached to the lid 20, where the counter will rotate to a certain angle when the filter cartridge 38 is replaced. The counter can have a dial or rotatable member that includes numbers or other indicia printed on one side that are visible from the outside of the filter assembly 38 through a hole, window, or transparent member in the lid 20. After a certain number of filter cartridge 38 replacements, the counter will not rotate, and the filter cartridge 38 can be prevented from being inserted into the housing 12.

[0093] With the filter assembly 10 including the transceivers 72, 74 and / or the controller 102 described above, the method can further include the step of counting each occurrence of installing the filter assembly 10 within the medical waste collection system 100 to indicate a number of uses of the filter assembly 10. This can also include indicating when the number of uses of the filter assembly 10 has reached a threshold to notify a user that the filter assembly 10 should be replaced. This can include indicating when either of the housing 12 and / or the filter cartridge 38 has reached a threshold number of uses. For example, when the filter cartridge 38 is intended to be a single-use filter cartridge 38, if the controller 102 identifies that the filter cartridge 38 has been previously installed and / or used, the controller 102 can prevent operation of the medical waste collection system 100. In another example, when the housing 12 is intended for use in up to four procedures, if the controller 102 identifies that the housing 12 has been previously installed and / or used for four medical procedures, the controller 102 can prevent operation of the medical waste collection system 100.

[0094] The method can also include the step of providing a visual indicator of the number of occurrences of installing a subsequent filter cartridge 38 within the housing 12 and / or the number of occurrences of installing the filter assembly 10 within the medical waste collection system 100.

[0095] The method can also include the step of counting each occurrence of installing the filter cartridge 38 within the housing 12 by sliding the filter cartridge 38 through the opening 18 to indicate a number of uses of the filter assembly 10. While not illustrated, it is contemplated that the housing 12 can include an antenna similar to the antenna 106 of the medical waste collection system 100, where the antenna of the housing 12 is configured to read data from the transceiver 72 of the filter cartridge and communicate the data to the controller 102 of the medical waste collection system 100. Based on the data communicated between the transceivers 72, 74 of the filter assembly 10 and the antenna 106 of the medical waste collection system 100, the controller 102 and / or operation of the medical waste collection system 100 can be similar or the same as described above with respect to operation of the medical waste collection system 100. For example, the controller 102 can be configured to count each occurrence of installing the cartridge 38 within the housing 12 to indicate a number of uses of the filter assembly 10. The controller 102 can then be configured to indicate when the number of uses of the filter assembly 10 has reached a threshold to notify a user that the filter assembly 10 should be replaced.

[0096] Referring back to Figure 12Furthermore, it is envisioned that the filter assembly 10 of the medical waste collection system 100 may optionally include a second sensor 202. The second sensor 202 may also be referred to as a wing sensor, connection sensor, port sensor, etc. The second sensor 202 may be disposed on or within the housing 12 of the filter assembly 10 and configured to identify the position of one or each of the wings 28A, 28B, 28C for selectively covering the ports 22A, 22B, 22C of the filter assembly 10. More specifically, the second sensor 202 may be configured to identify when each of the individual wings 28A, 28B, 28C is in a first position where the wings 28A, 28B, 28C cover the corresponding ports 22A, 22B, 22C, and when each of the individual wings 28A, 28B, 28C is in a second position where the corresponding ports 22A, 22B, 22C are exposed to allow the exhaust pipe to connect to the ports 22A, 22B, 22C. The second sensor 202 may include a proximity sensor, a Hall effect sensor, a mechanical switch, an optical sensor, or a similar sensor configured to detect the presence and / or absence of an object (such as wings 28A, 28B, 28C). For example, the second sensor 202 may include a Hall effect sensor configured to detect a magnetic field, and each of wings 28A, 28B, 28C may include a component 204 (also shown in Figures 16 to 17) that can be detected by the Hall effect sensor 202. Figure 17B (As shown in the diagram). Component 204 may also be referred to or described as an element, mark, identifier, label, part, feature, etc. Component 204 may include one of the ferromagnetic or magnetic materials detectable by the Hall effect sensor 202 and / or be formed at least partially of one of the ferromagnetic or magnetic materials detectable by the Hall effect sensor 202. As another example, component 204 may be formed of a reflective material capable of triggering an optical sensor. In yet another configuration, the component may be formed of a conductive material configured to trigger a capacitive or inductive sensor. This list is not intended to be exhaustive, and other combinations of sensors 202 and / or corresponding components 204 capable of identifying when wings 28A, 28B, 28C cover or uncover sockets 22A, 22B, 22C are contemplated.

[0097] For example, in operation, the second sensor 202, such as a Hall effect sensor, can be positioned and / or oriented on or within the housing 12 of the filter assembly 10 such that the Hall effect sensor is able to identify the position of the wing 28A, 28B, 28C based on changes in the magnetic field caused by the presence or absence of the member of the wing 28A, 28B, 28C. For example, depending on the presence of the member 204 near the second sensor when the wing 28A, 28B, 28C covers the corresponding socket 22A, 22B, 22C, the second sensor 202 can be positioned such that it detects a first magnetic field when the wing 28A, 28B, 28C is in the first position and covers the corresponding socket 22A, 22B, 22C. Alternatively, depending on the absence of the member 204 near the second sensor when the wing 28A, 28B, 28C exposes the corresponding socket 22A, 22B, 22C, the second sensor 202 can be positioned such that it can detect a second magnetic field (or the absence of a magnetic field) when the wing 28A, 28B, 28C is in the second position and exposes the corresponding socket 22A, 22B, 22C.

[0098] The reverse scenario is also contemplated, in which, depending on the absence of the member 204 near the second sensor when the wing 28A, 28B, 28C covers the corresponding socket 22A, 22B, 22C, the second sensor 202 and / or the member 204 are arranged on or within the housing 12 such that the second sensor 202 can detect a second magnetic field (or the absence of a magnetic field) when the wing 28A, 28B, 28C is in the first position and covers the corresponding socket 22A, 22B, 22C. In this scenario, depending on the presence of the member 204 near the second sensor when the wing 28A, 28B, 28C exposes the corresponding socket 22A, 22B, 22C, the second sensor 202 can detect a first magnetic field when the wing 28A, 28B, 28C is in the second position and exposes the corresponding socket 22A, 22B, 22C.

[0099] The second sensor 202 can further be connected to the controller 102 for controlling one or more operational features of the medical waste collection system 100. The controller 102 of the medical waste collection system 100 can be configured to adjust the settings of the vacuum source 306 (e.g., a blower assembly) based at least in part on signals received from the second sensor 202.

[0100] The medical waste collection system 100 can also include a user interface 112. The user interface 112 can include a display. The user interface 112 can also include a touchscreen, icons, buttons, switches, or similar user input mechanisms for controlling the operation of the system 100. The user interface 112 can be connected to the controller 102 and configured to input data or instructions to the controller 102 to control one or more operational features of the system 100. For example, the user interface 112 can include buttons or icons configured to allow a user to input settings for the operation of the vacuum source. The user interface 112 can also include buttons or icons for selecting the size, type, and / or number of surgical instruments connected to the system 100 via one or more of the outlets 22.

[0101] Referring to Figures 13 to 15 FIG. 3 illustrates an example configuration of a vacuum source (vacuum source 306) of the medical waste collection system 100. The vacuum source 306 can be disposed in a void or compartment 307 defined by a body component (H). The vacuum source 306 is in fluid communication with a smoke conduit 302 connected to the filter assembly 10 (filter assembly shown schematically). When the vacuum source 306 is operated, the vacuum source 306 draws fluid through one or more of the outlets 22A, 22B, 22C into the filter assembly 10. The vacuum source 306 includes a fan and a blower motor 308 for operating the fan. The vacuum source 306 can include a centrifugal fan, and the blower motor 308 can be a brushed motor. However, a person of skill in the art recognizes alternative embodiments utilizing different implementations of the vacuum source 306.

[0102] The sound attenuation enclosure 320 in which the vacuum source 306 is disposed serves to attenuate noise associated with the operation of the vacuum source 306. The sound attenuation enclosure 320 defines an inlet chamber 322 extending between a first enclosure inlet 322a at one end of the sound attenuation enclosure 320 and a second enclosure inlet 322b. The second enclosure inlet 322b receives filtered air passing through the exhaust opening 314. The sound attenuation enclosure 320 also defines an enclosure outlet 324 for directing filtered and heated air from the vacuum source 306 to the environment.

[0103] In addition to the sound attenuation enclosure 320, a muffler 321 can be attached to the centering ring 312 to further attenuate noise associated with the vacuum source 306. During operation of the vacuum source 306, cooling air is drawn from inside the waste collection unit 100 through the muffler 321. More specifically, the muffler 321 defines an inlet 319 for cooling air to enter the sound attenuation enclosure 320. The inlet 319 can include a valve that is in communication with and / or controlled by the controller 102. The controller 102 can be configured to open and close the valve of the inlet 319 based on operating conditions of the medical waste collection system 100 to ensure proper cooling of the blower motor. For example, the controller 102 can be configured to open the valve of the inlet 319 when the flaps 28A, 28B, 28C are in the first position and cover the corresponding ports 22A, 22B, 22C. When the flaps 28A, 28B, 28C are in the first position, air is prevented from flowing through the filter assembly 10 and thus cannot be used to cool the vacuum source 306, otherwise air would flow from the environment, through the filter assembly 10, and be used to cool the blower motor 306. When the flaps 28A, 28B, 28C are in the first position, opening the valve of the inlet 319 provides an alternative path for air to enter the sound attenuation enclosure 320 to cool the blower motor. Conversely, the controller 102 can be configured to close the valve of the inlet 319 when the flaps 28A, 28B, 28C are in the second position, exposing the corresponding ports 22A, 22B, 22C, and allowing air to flow from the environment, through the filter assembly 10. Air drawn from the external environment through the ports 22A, 22B, 22C can be used to cool the vacuum source 306. Closing the valve of the inlet 319 can provide the advantage of further dampening the sound produced by the vacuum source 306 during operation of the system 100 when additional cooling air via the inlet 319 is not needed. The cooling air provided through the inlet 319 can keep the blower motor 308 cool enough to avoid overheating and / or failure, even when: the smoke conduit 302 is clogged and / or all of the flaps 28A, 28B, 28C are in the first position and cover the respective ports 22A, 22B, 22C, thereby preventing external air from flowing into and through the filter assembly 10.

[0104] Reference Figures 16A to 17B FIG. 6 shows a configuration of the filter assembly 10 that includes a second sensor 202 and a member 204 on the flaps 28A, 28B, 28C. The second sensor and / or the member 204 are optional features of the filter assembly 10. It is not required that the filter assembly have one or either of these features.

[0105] As described above, the second sensor 202 can be positioned on or within the filter assembly 10 and configured to identify a position of the wing 28A, 28B, 28C covering the socket 22A, 22B, 22C defined by the housing 12 and / or the cover 20 of the filter assembly 10. The filter assembly 10 can include a single second sensor 202 capable of detecting the position of one or more wings 28A, 28B, 28C. Alternatively, as shown, the filter assembly can include a separate second sensor 202A, 202B, 202C for each of the wings 28A, 28B, 28C of the filter assembly 10. Figures 16A to Figure 17B

[0106] The member 204 can be any item disposed on and / or coupled to the wing 28A, 28B, 28C that can be identified and / or detected by the second sensor 202. For example, as described above, the member 204 can be formed of one of a ferromagnetic or magnetic material that can be detected by a Hall effect sensor 202. As another example, the member 204 can be formed of a reflective material capable of triggering an optical sensor. In yet another configuration, the member 204 can be formed of a conductive material configured to trigger a capacitive or inductive sensor. The combination of the second sensor 202 and the member 204 can be arranged on the filter assembly 10 such that the presence or absence of the member 204 detected by the second sensor 202 can indicate the position of the wing. For example, as shown, the second sensor 202 and the member 204 can be arranged on the filter assembly 10 such that the member 204 is proximate or adjacent to the second sensor 202 when the wing 28A, 28B, 28C is in the first position. In this arrangement, the second sensor 202 can be positioned generally beneath the respective socket 22A, 22B, 22C such that detection or identification of the member 204 by the second sensor 202 can indicate that the wing 28A, 28B, 28C is covering the respective socket 22A, 22B, 22C and that the absence of the member 204 detected or identified by the second sensor 202 can indicate that the wing 28A, 28B, 28C is in the second position and exposing the respective socket 22A, 22B, 22C. Figure 16B

[0107] Alternatively, as shown, the second sensor 202 and the member 204 can be arranged on the filter assembly 10 such that the member 204 is distal from the second sensor 202 when the wing 28A, 28B, 28C is in the first position. In this arrangement, the second sensor 202 can be positioned generally beneath the respective socket 22A, 22B, 22C such that detection or identification of the member 204 by the second sensor 202 can indicate that the wing 28A, 28B, 28C is in the second position and exposing the respective socket 22A, 22B, 22C and that the absence of the member 204 detected or identified by the second sensor 202 can indicate that the wing 28A, 28B, 28C is covering the respective socket 22A, 22B, 22C. Figure 16A ​​As shown, it is also contemplated that the second sensor 202 and the member 204 can be arranged on the filter assembly 10 such that the member 204 is out of detection / identification by the second sensor 202 when the wing 28A, 28B, 28C is in the first position. In this arrangement, detection or identification by the second sensor 202 of the member 204 being absent can indicate that the wing 28A, 28B, 28C is covering the respective port 22A, 22B, 22C, and detection or identification by the second sensor 202 of the member 204 being present can indicate that the wing 28A, 28B, 28C is in the second position and exposing the respective port 22A, 22B, 22C.

[0108] The second sensor 202 can also be configured to generate a signal based on the position of the wing 28A, 28B, 28C. For example, the second sensor 202 can be configured to generate a first signal when the wing(s) 28A, 28B, 28C is determined by the sensor to be in the first position and covering the respective port 22A, 22B, 22C. The second sensor 202 can also be configured to generate a second signal when the wing 28A, 28B, 28C is determined by the sensor to be in the second position and exposing the respective port 22A, 22B, 22C. It is also contemplated that the second sensor 202 can be configured to utilize an absence of a signal as an indication of the position of the wing 28A, 28B, 28C. For example, the second sensor 202 can be configured to generate a first signal when the wing 28A, 28B, 28C is in the first position and no signal when the wing 28A, 28B, 28C is in the second position, or vice versa.

[0109] The second sensor 202 can be configured to communicate a signal indicative of and / or identifying the position of the wing 28A, 28B, 28C to the controller 102. The signal from the second sensor 202 can include data specifically identifying whether the wing 28A, 28B, 28C is in the first position or the second position. For example, the signal from the second sensor 202 can include data indicative of the wing 28A, 28B, 28C being in the first position, and the controller 102 is configured to operate the system 100 based at least in part on the wing 28A, 28B, 28C being in the first position. Alternatively, the signal from the second sensor 202 can also be configured to include data indicative of the wing 28A, 28B, 28C being in the second position, and the controller 102 is configured to operate the system 100 based at least in part on the wing 28A, 28B, 28C being in the second position.

[0110] In another configuration of the system 100, the signal from the second sensor 202 can be configured such that the signal can include general (generic) data, such as true / false, yes / no, 1 / 0, or similar data based on the wing 28A, 28B, 28C being in the first position or not being in the first position, and the controller 102 is further configured to identify the position of the wing based on the signal received from the second sensor 202. For example, the second sensor 202 can be configured to send a signal to the controller 102 that includes data indicating “true” when the wing 28A, 28B, 28C is in the first position, and data indicating “false” when the wing 28A, 28B, 28C is not in the first position. The controller 102 can then be configured to employ a “true” response to indicate that the wing 28A, 28B, 28C is in the first position, and operate the system 100 based on the corresponding jack 22A, 22B, 22C being covered. Alternatively, the controller 102 can then be configured to employ a “false” response to indicate that the wing 28A, 28B, 28C is not in the first position, and operate the system 100 based on the corresponding jack 22A, 22B, 22C being exposed.

[0111] The controller 102 can also be configured to enable and / or disable operation of the system 100 based on the position of the wings 28A, 28B, 28C. For example, the controller 102 can be configured to disable operation of the vacuum source 306, and (by extension) the system 100, when all of the wings 28A, 28B, 28C are in the first position and cover the corresponding jacks 22A, 22B, 22C. Referring to FIG. 16, if all of the wings 28A, 28B, 28C are in the first position and cover the respective jacks 22A, 22B, 22C, there are no exposed jacks 22A, 22B, 22C. The controller 102 can be programmed and / or configured to interpret this as meaning that there is no exhaust duct 110 connected to the system 100, and thus can disable operation of the system 100.

[0112] Alternatively, when one or more of the wings 28A, 28B, 28C are in the second position and expose the corresponding jacks 22A, 22B, 22C, the controller can be configured to operate the system based on the size of the jacks 22A, 22B, 22C and / or the number of exposed jacks 22A, 22B, 22C. For example, the controller 102 can be configured to control operation of the system 100 based on the number of jacks 22A, 22B, 22C exposed by the corresponding wings 28A, 28B, 28C. In this example, if the second sensor 202A identifies that the first wing 28A is in the second position exposing the first jack 22A, as shown in FIG. 17A, the controller 102 can be configured to operate the system 100 based on the size of the first jack 22A. For example, the controller 102 can be configured to operate the system 100 based on the size of the first jack 22A, and / or the size of the first exhaust duct 110 connected to the first jack 22A. In this example, the controller 102 can be configured to operate the system 100 based on the size of the first jack 22A and / or the size of the first exhaust duct 110 connected to the first jack 22A, and / or the size of the first exhaust duct 110 connected to the first jack 22A. Figure 17Ashown, the controller 102 can be configured to operate the system 100 including the vacuum source 306 at a first volumetric flow rate. This can be based on the size, shape, etc. of the first port 22A, which in turn can identify the size of the surgical instrument and / or the exhaust tube 110 coupled to the system 100. Alternatively, if the second sensor 202B identifies that the second wing 28B is in the second position exposing the second port 22B, the controller 102 can be configured to operate the system 100 including the vacuum source 306 at a second volumetric flow rate. This can also be based on the size, shape, etc. of the second port 22B, which in turn can identify the size of the surgical instrument and / or the exhaust tube coupled to the system. The system 100 can also be configured such that if the second sensor 202C identifies that the third wing 28C is in the second position exposing the third port 22C, the controller 102 can be configured to operate the system 100 including the vacuum source 306 at a third volumetric flow rate. This can also be based on the size, shape, etc. of the third port 22B, which in turn can identify the size of the surgical instrument and / or the exhaust tube coupled to the system 100. Each of the first, second, and third volumetric flow rates can be the same as or different from one another. Further, the controller 102 can be configured to operate the system 100 at a volumetric flow rate corresponding to any combination of the first, second, and / or third ports 22A, 22B, 22C exposed by the corresponding wings 28A, 28B, 28C. For example, if multiple ports 22A, 22B, 22C are exposed by the corresponding wings 28A, 28B, 28C, the controller 102 can be configured to operate the system 100 at a higher volumetric flow rate than any of the first, second, or third volumetric flow rates. An example of this is shown in FIG. 3, where a combination of the first port 22A and the second port 22B are exposed by the corresponding wings 28A, 28B. Multiple ports 22A, 22B, 22C exposed by the corresponding wings 28A, 28B, 28C would indicate that multiple surgical instruments are coupled to the system 100, and thus, a high volumetric flow rate would be required as compared to when only a single instrument is coupled to the system 100. Figure 17B

[0113] The user interface 112 can also be configured to identify to the user which of the ports 22A, 22B, 22C are exposed and / or covered by the corresponding wings 28A, 28B, 28C. For example, as shown in FIG. 3, the user interface 112 can be configured to display a graphical representation of the system 100 including the ports 22A, 22B, 22C and the wings 28A, 28B, 28C. The graphical representation can be updated in real-time to indicate which of the ports 22A, 22B, 22C are exposed and / or covered by the corresponding wings 28A, 28B, 28C. For example, as shown in FIG. 3, the graphical representation can indicate that the first port 22A is exposed by the first wing 28A and the second port 22B is exposed by the second wing 28B. The graphical representation can also indicate that the third port 22C is covered by the third wing 28C. The graphical representation can also be updated in real-time to indicate the volumetric flow rate at which the system 100 is operating. For example, as shown in FIG. 3, the graphical representation can indicate that the system 100 is operating at a volumetric flow rate of 20 L / min. The graphical representation can also be updated in real-time to indicate the volumetric flow rate at which the system 100 is operating. For example, as shown in FIG. 3, the graphical representation can indicate that the system 100 is operating at a volumetric flow rate of 20 L / min. Figure 17A ​As shown, the user interface, via the controller 102, can be configured to utilize visual cues to identify to the user which of the ports 22A, 22B, 22C are exposed / concealed by the corresponding wing 28A, 28B, 28C. The user interface 112 can be configured to identify via text the ports 22A, 22B, 22C that are exposed / concealed, such as “concealed” or “closed” to indicate that the wing 28A, 28B, 28C is in the first position and / or “exposed” or “open” to indicate that the wing 28A, 28B, 28C is in the second position. Alternatively, the user interface 112 can be configured to identify the position of the wing 28A, 28B, 28C via a color coding system, such as a green light or dot to indicate that the wing 28A, 28B, 28C is in the second position and the port 22A, 22B, 22C is exposed. Alternatively, the user interface 112 can utilize a red light or dot to indicate that the wing 28A, 28B, 28C is in the first position with the port 22A, 22B, 22C concealed. The specific colors used to indicate which position the wing is in are not important, so long as the user understands which color indicates which wing position. It is also contemplated that the user interface 112 can be configured to provide an audible cue that identifies which of the ports 22A, 22B, 22C are exposed / concealed by the corresponding wing 28A, 28B, 28C.

[0114] A method of operating a filter assembly, the filter assembly including a vacuum pump, a wing that conceals a port, a sensor, and a controller, the method can include the step of receiving, with the controller, a signal from the sensor, the signal indicating that the wing is concealing the port. The method can also include the step of preventing, with the controller, operation of the vacuum pump based on the signal. The method can also include the steps of receiving, with the controller, a second signal from the sensor, wherein the second signal indicates that the wing has moved away from concealing the port, and enabling, with the controller, operation of the vacuum pump based on the second signal. The method can also include the step of displaying, on a user interface, one or more icons for controlling one or more operational features of the vacuum pump based on the second signal being received by the controller.
