- Dental suction tools include high volume evacuator (HVE) devices and saliva ejector devices.
- HVE devices and saliva ejector devices can be coupled with a source of negative pressure, for example, a vacuum or suction system, in order to transfer matter from a first location to a second location.
- a source of negative pressure for example, a vacuum or suction system
- saliva ejector devices are configured to remove excess saliva from a patient's mouth during a dental procedural
- HVE devices are configured to evacuate saliva and other matter from a patient's mouth during a dental procedure.
- HVE devices can be used to evacuate saliva, other biological matter, and non-biological matter including, but not limited to, dental restorative materials and restorations.
- HVE devices are commonly formed from rigid materials
- saliva ejector devices are formed from more flexible materials
- the central passageways in HVE devices are typically larger than the lumens or central passageways in saliva ejector devices.
- HVE device Inserting an HVE device into a patient's mouth can lead to inadvertent traumas, for example, lacerations or hematomas, in the patient's mouth. In many cases, the dental professional and/or patient may not notice these traumas when they occur because the patient's mouth has been numbed by a local anesthesia. Traumas caused by HVE devices can result in post-procedure discomfort for the patient and/or other complications, for example, infections that are of the viral, bacterial, and fungal sort.
- certain materials for example, biological and non-biological materials including materials that aid the dental professional during a procedure such as cotton rolls and gauze, can become lodged in the HVE device and/or suction system during a procedure and block the source of negative pressure or suction.
- the dental professional must stop working on the patient, turn the suction system off, disassemble or partially disassemble the HVE device and/or suction system, remove the blockage, reassemble the device, and turn the suction system on, before the professional can resume work on the dental procedure.
- sterilized objects for example, implants, grafts of the biologic sort (e.g., tissue and bone), and restorations
- an HVE device can inadvertently be evacuated through an HVE device and transported to an unsterile location, for example, a filter, within the suction system.
- the dental professional must spend a great deal of time re-sterilizing the evacuated object before it can be put into the patient's mouth.
- delays due to HVE device/system blockages and/or dental restoration (e.g., crowns, veneers, inlays, onlays, and implants) retrievals can be costly to the dental professional and burdensome for the dental professional's patients.
- large objects that are inadvertently evacuated with an HVE device can damage the suction system. Such damage can result in longer delays while the equipment is repaired in addition to substantial repair costs.
- Embodiments disclosed herein generally relate to HVE devices configured to evacuate saliva and other matter, for example, from a patient's mouth during a dental procedure. Some embodiments disclosed herein relate to HVE devices that comprise protective tips disposed on the device and configured to inhibit inadvertent traumas caused by the HVE device during a dental procedure. Additionally, various embodiments disclosed herein relate to HVE devices that comprise screening devices configured to prevent blockages in HVE devices and/or suction systems. Certain embodiments disclosed relate to HVE devices that comprise a receiving space disposed between a screening device and a suction tip to catch larger objects that are inadvertently evacuated with an HVE device and prevent the larger objects from further evacuation through the un-sterile suction system.

In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented here. It will be readily understood that the aspects of the present disclosure, as generally described herein, and illustrated in the Figures, can be arranged, substituted, combined, and designed in a wide variety of different configurations, all of which are explicitly contemplated and make part of this disclosure.
- Dental suction tools include high volume evacuator (HVE) devices and saliva ejector devices. HVE devices and saliva ejector devices can be coupled with a source of negative pressure, for example, a vacuum or suction system, in order to transfer matter from a first location to a second location. Generally, saliva ejector devices are configured to remove excess saliva from a patient's mouth during a dental procedural whereas HVE devices are configured to evacuate saliva and other matter from a patient's mouth during a dental procedure. For example, HVE devices can be used to evacuate saliva, other biological matter, and non-biological matter including, but not limited to, dental restorative materials and restorations. Accordingly, HVE devices are commonly formed from rigid materials, saliva ejector devices are formed from more flexible materials, and the central passageways in HVE devices are typically larger than the lumens or central passageways in saliva ejector devices.
- Inserting an HVE device into a patient's mouth can lead to inadvertent traumas, for example, lacerations or hematomas, in the patient's mouth. In many cases, the dental professional and/or patient may not notice these traumas when they occur because the patient's mouth has been numbed by a local anesthesia. Traumas caused by HVE devices can result in post-procedure discomfort for the patient and/or other complications, for example, infections that are of the viral, bacterial, and fungal sort.
- Additionally, certain materials, for example, biological and non-biological materials including materials that aid the dental professional during a procedure such as cotton rolls and gauze, can become lodged in the HVE device and/or suction system during a procedure and block the source of negative pressure or suction. To remedy such a blockage, the dental professional must stop working on the patient, turn the suction system off, disassemble or partially disassemble the HVE device and/or suction system, remove the blockage, reassemble the device, and turn the suction system on, before the professional can resume work on the dental procedure.
- Moreover, in some situations, sterilized objects, for example, implants, grafts of the biologic sort (e.g., tissue and bone), and restorations, can inadvertently be evacuated through an HVE device and transported to an unsterile location, for example, a filter, within the suction system. In these circumstances, the dental professional must spend a great deal of time re-sterilizing the evacuated object before it can be put into the patient's mouth. Because many dental professionals see patients in ten or fifteen minute increments, delays due to HVE device/system blockages and/or dental restoration (e.g., crowns, veneers, inlays, onlays, and implants) retrievals can be costly to the dental professional and burdensome for the dental professional's patients. Furthermore, in some cases, large objects that are inadvertently evacuated with an HVE device can damage the suction system. Such damage can result in longer delays while the equipment is repaired in addition to substantial repair costs.
- Embodiments disclosed herein generally relate to HVE devices configured to evacuate saliva and other matter, for example, from a patient's mouth during a dental procedure. Some embodiments disclosed herein relate to HVE devices that comprise protective tips disposed on the device and configured to inhibit inadvertent traumas caused by the HVE device during a dental procedure. Additionally, various embodiments disclosed herein relate to HVE devices that comprise screening devices configured to prevent blockages in HVE devices and/or suction systems. Certain embodiments disclosed relate to HVE devices that comprise a receiving space disposed between a screening device and a suction tip to catch larger objects that are inadvertently evacuated with an HVE device and prevent the larger objects from further evacuation through the un-sterile suction system.
- Several non-limiting examples of embodiments will now be described with reference to the accompanying figures, wherein like numerals refer to like elements throughout. The terminology used in the description presented herein is not intended to be interpreted in any limited or restrictive manner, simply because it is being utilized in conjunction with a detailed description of certain specific embodiments. Furthermore, embodiments can include several novel features, no single one of which is solely responsible for its desirable attributes or which is essential to practicing the technology herein described.

FIG. 1 schematically illustrates one example of an embodiment of adental evacuation device 100. Thedevice 100 has asuction end 110 and aconnection end 120 disposed opposite to the suction end. Theconnection end 120 may be configured to releasably attach to a source of negative pressure, for example, a suction or vacuum system. Thesuction end 110 can receive matter from a patient's mouth and the received matter can be evacuated through thedevice 100 during a dental procedure when theconnection end 120 is attached to a source of negative pressure. Thedevice 100 can include a length dimension defined, for example, between the most distal point of thesuction end 110 and the most proximal point of theconnection end 120. The length dimension can vary. For example, non-limiting ranges for the length dimension may be between about 3 and about 30 centimeters and between about 13 and 16 centimeters. In one embodiment, the length dimension of the device is about 14.5 centimeters. The recited lengths are not limiting and one of skill in the art will appreciate, in view of the disclosure, that the length can longer or shorter than the recited numbers in some embodiments. - The
dental evacuation device 100 includes anelongated body 200. Theelongated body 200 can be generally tube shaped and include anouter surface 210 and aninner surface 220. The inner surface defines a central passageway orlumen 245 extending through thebody 200 from thesuction end 110 to theconnection end 120 in a direction substantially parallel to the longitudinal axis of thedevice 100. The cross-section of thecentral passageway 245 can be generally polygonal, for example, rectangular, generally curvilinear, for example, round, oval, or circular, or generally polygonal and curvilinear. Similarly, the cross-section of theelongated body 200 can be generally polygonal, for example, rectangular, generally curvilinear, for example, round, oval or circular, or generally polygonal and curvilinear. Thecentral passageway 245 can have a uniform cross-section along the longitudinal axis of theelongated body 200 or thecentral passageway 245 can have a non-uniform cross-section along the longitudinal axis of theelongated body 200. For example, thecentral passageway 245 can taper or narrow from one of theelongated body 200 towards the other end. In other embodiments, the cross-section of thecentral passageway 245 is substantially the same along the longitudinal axis of theelongated body 200. - In embodiments where the cross-section of the
central passageway 245 is uniform along the length of the longitudinal axis, the area of the cross-section of thecentral passageway 245 can vary from embodiment to embodiment. For example, non-limiting ranges for the area of the cross-section of thecentral passageway 245 are between about 25 and about 3000 square millimeters. In one embodiment, the cross-section of thecentral passageway 245 may have an area of about 64 square millimeters. The width of thecentral passageway 245 can also vary. For example, non-limiting ranges for the width of thecentral passageway 245 are between about 5 and about 30 millimeters and between about 8 and about 10 millimeters. In one embodiment, the width of thecentral passageway 245 is about 9 millimeters. The recited numbers are not to be limiting. One of skill in the art will appreciate, in view of the disclosure, that the values can be greater or lesser than the recited numbers in some embodiments. - The
elongated body 200 can be configured to be generally rigid and can be formed of generally rigid materials including, but not limited to, polymers, plastics, thermoplastics, composite materials (e.g., carbon fiber reinforced plastic), organic materials, cellulosic materials, rubbers, metals, and the like. For example, in some embodiments, the elongated body comprises a United States Food and Drug Administration approved polypropylene that is not affected by bodily fluids and can be easily sterilized. - The
elongated body 200 can optionally include a transverse aperture or vent 230. Thevent 230 can be disposed in a side of theelongated body 200 in order to connect thecentral passageway 245 with the outside of thedental evacuation device 100. Thevent 230 can be configured to provide vacuum or suction relief to thecentral passageway 245, for example, in order to alleviate a high negative pressure which makes it difficult to remove thesuction end 110 if it attaches to any tissue inside the patient's mouth or to their lips. In some embodiments, theelongated body 200 includes a plurality ofvents 230 disposed circumferentially around theelongated body 200. Thevent 230 or plurality of vents can be any shape, including, for example, generally square, rectangular, oval, round, and the like. - In the illustrated embodiment, the
elongated body 200 includes ascreening device 240 disposed within thecentral passageway 240. Thescreening device 245 can be integral with theelongated body 200 or can be a separate component, for example. As discussed in further detail below, thescreening device 240 can be configured to block and/or catch objects that are over a certain size and prevent such objects from passing through thecentral passageway 245. - Still referring to
FIG. 1 , thedental evacuation device 100 includes aprotective tip 300 disposed over theelongated body 200 at thesuction end 110 of thedevice 100. Theprotective tip 300 can be disposed over at least a portion of theouter surface 210. Theprotective tip 300 can be disposed over at least a portion of theinner surface 220. The portion of theprotective tip 300 that is disposed over theouter surface 210 of theelongated body 200 can be referred to as theexternal portion 320 of the tip. Similarly, the portion of theprotective tip 300 that is disposed over theinner surface 220 of theelongated body 200 can be referred to as theinternal portion 310 of the tip. Although the protective material is shown covering only a portion of the device, it should be understood that the protective material can cover any amount of the device up to, for example 100%. In some aspects the entire body, for example, can be made of or coated with a suitable protective material, including the materials described herein. For example, from 5% to about 100% of the exterior of the elongated body may be made of, coated or covered by a protective material. - The
protective tip 300 can include at least one distal contour or face 330 disposed between theinternal portion 310 andexternal portion 320. Thedistal contour 330 can be generally blunt to minimize the sharpness of theprotective tip 300. The shape of theprotective tip 300 can vary. For example, in some embodiments, theprotective tip 300 can be formed such that thedistal contour 330 is substantially planar. In other embodiments, theprotective tip 300 can be formed such that thedistal contour 330 is not substantially planar, for example. In some embodiments, the shape of theprotective tip 300 can depend, in part, on the shape of the distal end of theelongated body 200. The interface between thedistal contour 330 andinternal portion 310 can define asuction aperture 340 configured to receive matter therethrough. Thesuction aperture 340 can provide access to thecentral passageway 245 such that matter can pass through theprotective tip 300 into thecentral passageway 245. - Turning now to
FIG. 2 , a front view of the example embodiment ofFIG. 1 is shown. In use, thedevice 100 can be coupled with a suction system at thesuction end 120 and thesuction end 110 andprotective tip 300 can be inserted into a patient's mouth to evacuate matter therefrom. After the dental procedure is over, thedevice 100 can be decoupled from the suction system and discarded or sterilized for subsequent use. Theprotective tip 300 can be formed of any suitable material to provide protection to the mouth of the patient. For example, theprotective tip 300 can be formed of a relatively soft material configured to protect a patient from the sharper and more rigidelongated body 200. A non-limiting list of suitable materials for theprotective tip 300 includes thermoplastic elastomers, rubbers, vulcanizates, and the like. In some embodiments, theprotective tip 300 can include, for example, a cross-linked mixture of ethylene propylene diene monomer (EPDM) rubber and polypropylene, for example, Santoprene™. The selection of the material of theprotective tip 300 and the blunt shape of the tip can act in concert to protect a patient's mouth from trauma induced by thedevice 100. - Turning now to
FIG. 3A , a cross-section of the example embodiment ofFIG. 1 is shown taken along the line 3-3 ofFIG. 2 . As discussed above, thescreening device 240 can be disposed within thepassageway 245 between thesuction end 110 and theconnection end 120 of thedevice 100. In some aspects, without being limited thereto, thescreening device 240 can be offset from the most distal point of thesuction end 110 by about 0.50 centimeters to about 6 centimeters or any distance therebetween, for example. In some embodiments, thescreening device 240 can be offset from the most distal point on thesuction end 110 by about 1.0 to about 3.0 centimeters. In some embodiments, thescreening device 240 can be offset from the most distal point on thesuction end 110 in terms of a percentage of the entire length of thedevice 100. For example, thescreening device 240 can be offset from the most distal point on thesuction end 110 by a distance that is between about 5% and about 95% of the entire length of thedevice 100. In some embodiments, thescreening device 240 can be offset from the most distal point on thesuction end 110 by a distance that is between about 5% and about 25% of the entire length of the device, for example, about 5%, about 6%, about 7%, about 8%, about 9%, about 10%, about 11%, about 12%, about 13%, about 14%, about 15%, about 16%, about 17%, about 18%, about 19%, about 20%, about 21%, about 22%, about 23%, about 24%, or about 25% of the entire length. In some embodiments, thescreening device 240 can be offset from thesuction end 110 to create a receivingspace 400 within thecentral passageway 245. For example, the receivingspace 400 can be the entire volume of space from thescreening device 240 to the suction end. - As schematically depicted in
FIG. 3B , the receivingspace 400 can be configured to receive and house objects, for example, acrown 390, that are evacuated through thesuction end 110 of the device but cannot pass through thescreening device 240. For example, in some embodiments thescreening device 240 can be configured to prevent biologic and non-biologic materials including, but not limited to, cotton balls, pieces of gauze, dental restorations, for example, dental implants, dental implant components, and the like from passing therethrough. Dental implants, components of a dental implant, or dental restorations that are evacuated from a patient's mouth by thedevice 100 can be received and stored within the receivingspace 400 until a dental professional removes the received component, implant, or restoration from thedevice 100. Accordingly, inFIG. 3 , a dental professional can remove the receivedcrown 390 from the receivingspace 400 instead of having it pass through thedevice 100 and into the attached suction system. Thus, the receivingspace 400 can act as a catch mechanism and prevent blockages of thedevice 100 or attached suction system, damage to the suction system, and/or loss of sterilized dental objects. - Still referring to
FIG. 3 , theinternal surface 310 of theprotective tip 300 can be larger than theexternal surface 320 such that the protective tip extends further down theinner surface 220 of theelongated body 200 than theouter surface 210. Theinternal surface 310 can act to protect objects that are received within the receivingspace 400 from the more rigid and hardelongated body 200. In other embodiments, theinternal surface 310 andexternal surface 320 of theprotective tip 300 can be equally sized. - Turning now to
FIG. 4 , a top view of thedental evacuation device 100 ofFIG. 1 is schematically depicted showing thescreening device 240 disposed within thedevice 100. Thescreening device 100 can act as a screen, filter, sieve, sifter, or sorter to prevent objects over a certain size from passing through thedevice 100 to the attached suction system. As mentioned above, screening larger objects can prevent blockages within thedevice 100 or suction system and can also prevent damage to the suction system caused by the evacuation of larger solid objects. Also, thescreening device 240 and elongated body can act to catch dental objects and restorations, for example, custom dental implants or sterilized components, before the objects are evacuated through thedevice 100 into the suction system. - The
screening device 240 can includeopenings 240 configured to allow fluids biologic and non-biologic, air, other gases, and objects smaller than a certain size to pass through the screening device. The size and shape of theopenings 242 can vary. In some embodiments, theopenings 242 may be similarly sized and shaped. For example, the screening device can include a fine screen or mesh. The openings can be of any suitable size, for example, to block or capture desired materials, while permitting sufficient suction and passage of materials such as saliva and blood, for example. For example, theopenings 242 can be substantially polygonal and have an area between about 0.5 and about 4.0 square millimeters. In some embodiments, theopenings 242 are generally rectangular and have an area between about 2.0 and 2.5 square millimeters, for example, an area of about 2.0, 2.05, 2.1, 2.15, 2.2, 2.25, 2.3, 2.35, 2.4, 2.45, or 2.5 square millimeters. In one embodiment, the openings are generally rectangular have an area of about 2.25 square millimeters, for example. - In another embodiment, the openings are generally round with an area of between about 2.0 and 2.5 square millimeters, for example. In other embodiments, a
screening device 240 can includeopenings 242 that are differently shaped. For example, afirst opening 242 can be generally curvilinear and asecond opening 242 can be generally polygonal. - In some aspects the
screening device 240 can include parallel openings or a “grate” type configuration, rather than the cross hatched design that is depicted, for example. Any suitable design can be used that can block or capture objects that are sucked into the device, but which should not pass into the suction apparatus. The size and shape of theopenings 242 can be selected based in part on the dental procedure and the technical specifications of the suction system. For example, if the suction system thedevice 100 connects to is not capable of evacuating objects having a cross-sectional area over a certain size, theopenings 242 can be configured to be smaller than the certain size to inhibit damage to and/or prevent malfunction of the suction system. The size and shape of theopenings 242 can also be selected to maximize the efficiency of suction through thescreening device 240. For example, the size and shape of theopenings 242 can be configured to maximize the negative pressure or suction through thescreening device 240 while simultaneously acting to filter, screen, or catch objects. - Turning now to
FIG. 5 , one example of an embodiment of anelongated body 500 used to form a dental evacuation device is schematically illustrated. Theelongated body 500 is generally tubular and includes anouter surface 510 and aninner surface 520. Theinner surface 520 defines acentral passageway 545 running through thebody 500 between adistal end 540 and aproximal end 530. Theelongated body 500 can be formed using a variety of suitable methods, including for example, injection molding. In some embodiments, theelongated body 500 may include, for example, a rigid polypropylene. - The
elongated body 500 can also include a depressed orinset region 550 disposed near thedistal end 540 in theouter surface 510. Thedepressed region 550 can be used to define a space or area for molding, or otherwise attaching, a protective tip (not shown) to theelongated body 500. The elongated body can also include one or more securement orengagement apertures 560 disposed near thedistal end 540 and extending through theouter surface 510 andinner surface 520. Thesecurement apertures 560 can be configured to receive a portion of a protective tip (not shown) to secure the protective tip relative to theelongated body 500. In some embodiments, a protective tip can be over-molded to theelongated body 500 and the liquid material that forms the tip can seep through thesecurement apertures 560 during the injection molding process such that the formed protective tip extends through theapertures 560 in theelongated body 500. In some embodiments, theelongated body 500 can be released from a mold using a release agent, for example, a silicone release agent. One having skill in the art will understand that the devices and components disclosed herein can be formed using a variety of suitable methods. Thus, theelongated body 500 does not have to include adepressed region 550 orsecurement apertures 560. Similarly, some embodiments of HVE devices disclosed herein can be manufactured as a single piece. - Some embodiments relate to methods of using the devices described herein. Some embodiments relate to methods of performing dental procedures or medical procedures using a device as described herein. For example, some embodiments relate to methods of evacuating material from the mouth of a patient by providing a device as described herein with instructions for attaching the device to a suction apparatus and/or instructions for using device during a dental procedure. The methods can include methods and instructions for removal of debris from the receiving space of a device, etc. The methods can include inserting and/or instructions for contacting the device with or inserting the device into the body of the patient, for example, the mouth, and removing material such as saliva, blood and other matter from the patient. The methods can include connecting and/or instructions for connecting the device with a suction system, vacuum system, negative pressure system, and/or pressure delivery system.

FIG. 6 is a block diagram schematically depicting amethod 600 of manufacturing a dental evacuation device, according to one embodiment.Method 600 includes the steps of forming an elongated body member with a first material, the elongated body member having a first end, a second end, an inner surface, an outer surface, and a screen, wherein the inner surface defines a central passageway extending through the body member from the first end to the suction end, wherein the screen is positioned within the central passageway between the first end and the second end as illustrated inblock 602 and forming a protective tip with a second material on the elongated body, the protective tip being attached to and extending from the second end of the body member and defining an aperture configured to provide access to the central passageway as illustrated inblock 604. Those of skill in the art will understand and appreciate that the various embodiments of dental evacuation devices disclosed herein can be manufactured using a variety of different methods. - The foregoing description details certain embodiments of the devices and methods disclosed herein. It will be appreciated, however, that no matter how detailed the foregoing appears in text, the devices and methods can be practiced in many ways. As is also stated above, it should be noted that the use of particular terminology when describing certain features or aspects of the invention should not be taken to imply that the terminology is being re-defined herein to be restricted to including any specific characteristics of the features or aspects of the technology with which that terminology is associated. The scope of the disclosure should therefore be construed in accordance with the appended claims and any equivalents thereof.
- It will be appreciated by those skilled in the art that various modifications and changes may be made without departing from the scope of the described technology. Such modifications and changes are intended to fall within the scope of the embodiments, as defined by the appended claims. It will also be appreciated by those of skill in the art that parts included in one embodiment are interchangeable with other embodiments; one or more parts from a depicted embodiment can be included with other depicted embodiments in any combination. For example, any of the various components described herein and/or depicted in the Figures may be combined, interchanged or excluded from other embodiments.
- With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.
- It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”
- While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope and spirit being indicated by the following claims.
