BACKGROUND

1. Field

Embodiments disclosed herein relate generally to dental tools. More specifically, certain embodiments concern devices that can be coupled with a source of negative pressure, for example, a suction system, to evacuate matter from a patient\'s mouth during a dental procedure.

2. Description of the Related Art

Dental professionals often use suction devices to evacuate or remove saliva, other fluids, biological debris, and other matter from the mouths of patients during various procedures. In procedures where a dental professional is required to evacuate a substantial amount of matter, a high volume evacuator (hereinafter, “HVE”) device may be used. Embodiments disclosed herein relate to HVE devices and methods for evacuating matter from a patient\'s mouth during a dental procedure.

SUMMARY

The devices and methods disclosed herein each have several aspects, no single one of which is solely responsible for their desirable attributes. Without limiting the scope of the claims, some prominent features will now be discussed briefly. Numerous other embodiments are also contemplated, including embodiments that have fewer, additional, and/or different components, steps, features, objects, benefits, and advantages. The components, aspects, and steps may also be arranged and ordered differently. After considering this discussion, and particularly after reading the section entitled “Detailed Description of Certain Embodiments,” one will understand how the features of the devices and methods disclosed herein provide advantages over other known devices and methods.

In one embodiment, a dental evacuation device for connection to a suction system may include, for example, an elongated body member, a protective tip, and a screening device. The elongated body member may include or be formed of, for example, a first material, the elongated body member extending along a longitudinal axis and having a connection end, a suction end, an inner surface, and an outer surface, wherein the inner surface defines a central passageway extending through the body member from the connection end to the suction end, a protective tip, and a screening device. The protective tip may include or be formed of, for example, a second material and the protective tip may be disposed over and extending from the suction end of the body member. The protective tip may define a suction aperture configured to provide access to the central passageway. The screening device can be positioned within the central passageway between the connection end and the suction end.

In certain aspects, the screening device can be offset from the suction end of the central passageway and comprise a receiving space disposed between the screening device and the suction end. The elongated body can also include a transverse aperture disposed between the suction end and the connection end, for example, between the screening device and the connection end. The elongated body can also include a securement aperture disposed between the suction and the connection end, for example, between the screening device and the suction end. At least a portion of the protective tip can be disposed within the securement aperture.

In other aspects, the screening device can be disposed on a plane that lies substantially normal to the longitudinal axis and the screening device can include a plurality of openings configured to allow the passage of liquids and gases through the screening device. The openings can be substantially polygonal, substantially curvilinear, and the like, for example. The openings can have a cross-sectional area, for example, of between about 0.5 and 4.0 square millimeters, for example, between about 2.0 and 2.5 square millimeters. The screening device can be separate from or integral with the elongated body member. At least a portion of the protective tip can be disposed over at least a portion of the inner surface and at least a portion of the protective tip can be disposed over a portion of the outer surface. In some aspects, the first material can be the same as the second material and in other aspects, the first material and the second material can be different. The first material can comprise or be formed of polypropylene and the second material can comprise or be formed of a thermoplastic elastomer, for example, ethylene propylene diene monomer rubber. The protective tip can include a blunted ridge circumscribing the suction aperture and the blunted ridge can comprise a distal contour, wherein the distal contour is not planar.

In another embodiment, a dental evacuation device for connection to a suction system can include, for example, an elongated member, a protective tip, and a screening device. The elongated member can include, for example, polypropylene and extend along a longitudinal axis. The elongated body can have a connection end, a suction end, an inner surface, and an outer surface, wherein the inner surface defines a central passageway extending through the member from the connection end to the suction end. The elongated body may have a transverse aperture disposed between the suction end and the connection end. The protective tip can include, for example, a cross-linked mixture of ethylene propylene diene monomer rubber and polypropylene. The protective tip can be disposed over and extending from the suction end of the elongated member, the protective tip defining a suction aperture configured to provide access to the central passageway. The protective tip can include, for example, a blunted ridge circumscribing the suction aperture. The screening device may be positioned within the central passageway between the transverse aperture and the connection end, the screening device comprising a plurality of openings configured to allow the passage of liquids and gases through the screening device, wherein the openings are substantially polygonal and have a cross-sectional area of between about 2.0 square millimeters and about 2.5 square millimeters, for example.

In yet another embodiment, a dental evacuation device for connection to a suction system may include, for example, an elongated body member, a protective means, and a screening means. The elongated body may have, for example, a connection end, a suction end, an inner surface, and an outer surface, wherein the inner surface defines a central passageway extending through the body member from the connection end to the suction end. The protective means can be disposed over a portion of the elongated body member for protecting a patient from the suction end of the elongated body member. The screening means can be positioned within the central passageway for screening matter passing therethrough.

In another embodiment, a dental evacuation system may include, for example, a delivery device configured to produce a source of negative pressure and a dental evacuation device. The dental evacuation device may include, for example, an elongated body member, a protective tip, and a screening device. The elongated body member may include, for example, a first material, extend along a longitudinal axis, and have a connection end, a suction end, an inner surface, and an outer surface, wherein the inner surface defines a central passageway extending through the body member from the connection end to the suction end.
