[0001] Cross-reference to related patent applications This application claims priority to U.S. Provisional Patent Application No. 62 / 421,911, filed November 14, 2016, U.S. Provisional Patent Application No. 62 / 457,708, filed February 10, 2017, and U.S. Provisional Patent Application No. 62 / 519,049, filed June 13, 2017, each of which is incorporated herein by reference in its entirety. [Background technology]

[0002] background Standard toothbrush designs are not ideal for use in hospitals or other medical facilities where patients may have compromised immune systems. In these settings, there is an increased risk of contracting pneumonia, for example. Therefore, it is important to adhere to a proper oral care regimen that includes brushing three to four times per day.

[0003] Standard toothbrushes are reused repeatedly, so their use creates the risk of bacterial infection.In addition, standard toothbrushes are also not suitable for some patients; because patients may not be able to spit or otherwise remove liquid from their mouths voluntarily, may not have easy access to water, or may have difficulty holding and using toothbrushes with standard size and shape.Standard toothpaste may also be unsuitable for use by such patients, and it may be difficult for such patients to find the right amount of toothpaste and apply it to the toothbrush.

[0004] In many situations, medical procedures, such as oral care, must be repeated multiple times. For example, in oral care, a series of oral care products must be used in a repetitive manner, such as for periodic cleaning sessions that may involve evacuation, brushing the teeth, and wiping the mouth and gums. With each procedure occurring at predetermined intervals, such as every 2-3 hours, it can be cumbersome for a medical professional or patient to repeatedly collect the necessary equipment throughout the day.

DETAILED DESCRIPTION OF THE INVENTION

[0008] Detailed Description In various described embodiments, the oral care product improves compliance with an oral care regimen by providing all the tools and accessories necessary to complete the regimen without requiring significant effort by the patient or healthcare provider. In various exemplary embodiments, an oral care system for use in a hospital setting includes an oral care device (e.g., a toothbrush as shown in FIG. 1) and a unit-dose container of oral fluid (e.g., as shown in FIG. 2). The oral care device and / or oral care system may be intended for single use. Various embodiments of the oral care system are described in further detail below.

[0009] Referring initially to FIG. 1 , a side perspective view of an oral care device, such as a toothbrush 100, is shown according to an exemplary embodiment. The toothbrush 100 includes a handle 102 connected to a stem 104, which is connected to a head 106. The head 106 includes bristles 116 used to clean a patient's teeth. In some embodiments, the toothbrush 100 also includes supports 108 and 110 between the handle 102 and the stem 104 to provide length and stability to the toothbrush 100. Furthermore, in certain embodiments, the toothbrush 100 includes a suction mechanism. In such embodiments, the supports 108 and 110 house components of the suction mechanism. Suction is then provided by a device external to the toothbrush 100 and connected to the toothbrush 100 by tubing. Once the suction device external to the toothbrush 100 is activated, the patient may initiate suction on the head 106 of the toothbrush 100. For example, the patient may cover a hole located on the handle 102 or press a button on the toothbrush 100 to provide suction.

[0010] Referring now to FIG. 2 , a cross-sectional view of a unit-dose oral fluid container 200 according to an exemplary embodiment is shown. In certain embodiments, the oral fluid is an antiseptic fluid. Oral fluid container 200 defines a receptacle 202 within oral fluid container 200. Receptacle 202 is sized and configured to provide a stable base for oral fluid container 200. Receptacle 202 also serves as a reservoir and is configured to hold a volume of oral fluid 204, such as an antiseptic fluid. In some embodiments, receptacle 202 is configured to hold between 9.0 mL and 10.0 mL of oral fluid 204, and in certain embodiments, receptacle 202 is configured to hold 9.5 mL of oral fluid 204. The receptacle 202 portion of oral fluid container 200 may be cylindrical, although receptacle 202 may have different shapes in various embodiments. The top portion of oral fluid container 200 also includes a funnel 216 (e.g., a protrusion having a mouth and a base that narrows from the mouth to the base, with the base adjacent oral fluid 204 and the mouth having a shape that may be circular, oval, square, rectangular, etc.), and an internal chamber 206 within oral fluid container 200 provides a channel between receptacle 202 and funnel 216. In various arrangements, receptacle 202 is connected to funnel 216 via a conical extension region 226 (e.g., shaped like an inverted funnel).

[0011] Internal chamber 206 has an hourglass shape and includes an inlet 208 and an outlet 210. Inlet 208 provides a connection between funnel 216 and internal chamber 206. Outlet 210 provides a connection between internal chamber 206 and receptacle 202. Inlet 208 is defined by a first chamber 218 connected to funnel 216. A second funnel portion 222 connects first chamber 218 to a neck portion 214, which has a reduced diameter relative to first chamber 218 and second chamber 220. Outlet 210 is defined by a second chamber 220. Second chamber 220 is connected to neck portion 214 via an inverted funnel portion 224. Additionally, outlet 210 includes a pierceable partition through which toothbrush 100 must pass to use the oral fluid container. For example, in some embodiments, outlet 210 is covered by seal 212 prior to use. Alternatively, in other embodiments, outlet 210 is covered by a septum (e.g., as described below with reference to Figures 5A-5C), a cover with a cross cut (e.g., similar to foam cover 666 or sponge cover 766, described below with reference to Figures 9 and 10A and 10B, respectively).When not in use, internal chamber 206, and particularly second chamber 220, provides a housing for toothbrush 100 of Figure 2A (e.g., as shown in Figure 6A).

[0012] Neck portion 214, which has a reduced diameter relative to first chamber 218 and second chamber 220, is configured to remove excess oral fluid 204 from toothbrush 100 when the toothbrush is removed from internal chamber 206 for use (e.g., in the illustrated embodiment, the reduced diameter of neck portion 214 forces excess oral fluid 204 from toothbrush 100 through a scrubbing effect). Internal chamber 206 also facilitates the passage of saliva and oral fluid waste (hereinafter "brushing waste") spat out or expelled by the patient from funnel 216 to receptacle 202 during or after the patient's use of toothbrush 100. Funnel 216 provides a larger target area for the patient to collect brushing waste while brushing to minimize mess associated with spitting used oral fluid into receptacle 202.

[0013] In some embodiments, oral fluid container 200 is manufactured using injection molding. In other embodiments, rather than forming neck portion 214 using injection molding, a separate element is placed inside internal chamber 206 after injection molding, thereby creating neck portion 214 with a reduced diameter. In yet other embodiments, rather than forming second funnel portion 222, neck portion 214, and inverted funnel portion 224 together with the rest of oral fluid container 200 using injection molding, a separate element is placed inside internal chamber 206 after the rest of oral fluid container 200 is injection molded, thereby creating second funnel portion 222, inverted funnel portion 224, and neck portion 214. Additionally, in various embodiments, oral fluid container 200 is configured to be symmetrical about an axis extending through the center of oral fluid container 200.

[0014] In various embodiments, unit dose oral fluid container 200 is designed to be spill-resistant. Thus, in various arrangements, unit dose oral fluid container 200 is designed with specific spill-resistant dimensions. FIG. 3 is a cross-sectional view of the unit dose oral fluid container of FIG. 2 with such dimensions, according to an exemplary embodiment. In the embodiment of FIG. 3, oral fluid container 200 has an overall height of 4.5 inches. From the base of exemplary receptacle 202 to the base of funnel 216, receptacle 202 is 3.5 inches high, and the portion of receptacle 202 with a constant diameter (i.e., not including conical extension region 226) is 3.0 inches high and 1.5 inches in diameter. The funnel 216 is 2.5 cm (1.0 inch) high and has a top diameter of 5.1 cm (2.0 inch). The inlet 208 of the internal chamber 206 and the first chamber 218 defining the inlet 208 are 1.9 cm (0.75 inch) in diameter. The outlet 210 and the second chamber 220 defining the outlet are also 1.9 cm (0.75 inch) in diameter, and the outlet 210 terminates 2.5 cm (1.0 inch) above the base of the receptacle 202. The first chamber 218 is 1.3 cm (0.5 inch) high and the second chamber 220 is 2.5 cm (1.0 inch) high. The neck portion 214 is 1.3 cm (0.5 inch) high and 1.3 cm (0.5 inch) in diameter. Second funnel portion 222, neck portion 214, and inverted funnel portion 224 have a combined height of 2.5 cm (1.0 inch). Overall, oral fluid container 200 has a wall width of 0.15 cm (0.06 inch). Such dimensions make oral fluid container 200 spill-resistant to up to 15 mL to accommodate both unused oral fluid and toothpaste washout of saliva and oral fluid (e.g., after use of toothbrush 100).

[0015] 3, it should be understood that other dimensions may also be used to achieve the same or substantially the same ratios and configurations as those described above, such dimensional ratios allowing the oral fluid container 200 to maintain its spill-resistant properties.

[0016] 4A-4C, schematic diagrams of unit-dose oral fluid container 200 are shown in various orientations illustrating the spill-resistance characteristics of oral fluid container 200 according to an exemplary embodiment. While FIG. 4A shows oral fluid container 200 in an upright position with a combination of unused oral fluid and toothpaste effluent 250 (e.g., after use of toothbrush 100), oral fluid container 200 may alternatively contain only oral fluid 204 (e.g., before use of toothbrush 100). FIG. 4B shows oral fluid container 200 in a horizontal position with a combination of unused oral fluid and toothpaste effluent 250. As shown, when oral fluid container 200 is in the horizontal position, a combination of unused oral fluid and toothpaste effluent 250 does not exit oral fluid container 200 through interior chamber 206, but instead is maintained within receptacle 202. 4C shows oral fluid container 200 in an upside-down orientation. As shown, the unused oral fluid and toothpaste waste combination 250 is again maintained within receptacle 202 rather than exiting oral fluid container 200.

[0017] 5A-5C, side views of a septum 300 according to an exemplary embodiment are shown. The septum 300 includes a base 302 and a crown portion 304 that defines an opening 306. The crown portion 304 includes two or more flexible sections 308 separated by a slice in the septum material that defines the opening 306. As shown in FIG. 5A, in a natural state, the flexible sections are joined together. Thus, the septum 300 as shown in FIG. 5A is in a closed configuration. However, the flexible sections 308 are configured to separate and thereby open the opening 306 when subjected to a force. For example, FIG. 5B shows the toothbrush 100 entering through the opening 306 in the septum 300. FIG. 5C shows the head 106 of the toothbrush 100 having substantially passed through the opening 306 in the septum 300.

[0018] Thus, in some embodiments, septum 300 is coupled to interior chamber 206 of oral fluid reservoir 200 (e.g., at inlet 208 or outlet 210). Flexible section 308 allows toothbrush 100 to enter and exit through opening 306 in septum 300. However, because septum 300 is in a closed configuration in its natural state, septum 300 provides additional protection against spillage, thereby increasing the spill-resistance of oral fluid reservoir 200 while maintaining an opening for toothbrush 100. In some embodiments, septum 300 also removes excess oral fluid 204 (e.g., as two or more flexible sections 308 push excess oral fluid 204 out of toothbrush 100) when toothbrush 100 is removed from interior chamber 206 by pulling toothbrush 100 in opposite directions through septum 300.

[0019] 6A-6C, a method of using an oral-care system 280 including a toothbrush (e.g., toothbrush 100) and a unit-dose oral fluid container (e.g., oral fluid container 200) according to an exemplary embodiment is depicted. FIG. 6A shows oral-care system 280 in a storage configuration, with toothbrush 100 held within internal chamber 206 of container 200. As such, seal 212 is still intact and receptacle 202 contains oral fluid 204. While the embodiment shown in FIG. 6A includes seal 212 to prevent toothbrush 100 from entering oral fluid container 200 too soon, oral-care system 280 may alternatively use any other mechanism (e.g., septum 300, etc.) that prevents toothbrush 100 from being removed from internal chamber 206 and / or moved into oral fluid 204 prior to use.

[0020] To begin using oral care system 280, the patient or caregiver pushes toothbrush 100 in the direction depicted by arrow 282 in FIG. 6B to pierce a pierceable partition separating toothbrush 100 from oral fluid 204. In the illustrated embodiment, the pierceable partition is seal 212, although oral fluid container 200 may additionally or alternatively include, for example, septum 300. Toothbrush 100 is then exposed to oral fluid 204 in receptacle 202, and toothbrush 100 may be pushed through outlet 210 and into oral fluid 204 to become saturated. Next, as shown in FIG. 4C, the patient or caregiver pulls toothbrush 100 out of internal chamber 206 in the direction depicted by arrow 284 in FIG. 6C to begin oral treatment. As the toothbrush 100 is withdrawn from the internal chamber 206, the neck portion 214 handles the head 106 of the toothbrush 100, removing excess oral fluid 204. Additionally, in embodiments including the septum 300, the flexible section 308 of the crown portion 304 handles excess oral fluid 204 from the toothbrush 100. The patient or caregiver may then use the toothbrush 100 in a standard manner to brush the patient's teeth. The patient spits into the funnel 216 during or after brushing to remove oral fluid from the mouth. Once the patient has completed the oral care procedure, the oral care system 280 is disposed of. In some arrangements, the patient or caregiver reinserts the toothbrush 100 into the internal chamber 206 before disposing of the oral care system 280.

[0021] Referring now to FIG. 7 , a schematic side view of an oral-care system 480 according to another exemplary embodiment is shown. Oral-care system 480 also includes a toothbrush, shown as toothbrush 100, and a unit-dose oral fluid container, shown as oral fluid container 400. However, unlike oral-care system 280, oral-care system 480 includes a separate reservoir 403 and drained fluid container 430. As shown, reservoir 403 and drained fluid container 430 are connected via a bottom edge 432 and a top edge 434 and separated by a gap 436 to prevent reservoir 403 and drained fluid container 430 from interfering with each other. As shown in FIG. 7 , reservoir 403 and drained fluid container 430 are completely separate containers; however, in other embodiments, reservoir 403 and drained fluid container 430 may be at least partially connected (e.g., at the bottom of reservoir 403 and drained fluid container 430).

[0022] As shown, reservoir 403 defines a receptacle 402 configured to hold an oral fluid, such as a disinfectant, within reservoir 403. For example, in some embodiments, receptacle 402 is configured to hold 9.5 mL of oral fluid. Receptacle 402 is connected via a conical extension 440 to a top portion 438 with an inlet 408. Top portion 438 and inlet 408 are sized to allow for insertion and removal of toothbrush 100.

[0023] Reservoir 403 also includes an interior chamber 406. Like interior chamber 206, interior chamber 406 also includes an outlet 410 that provides a connection between interior chamber 406 and receptacle 402. Interior chamber 406 is defined by a first chamber 418 connected to top portion 438. A funnel portion 422 connects first chamber 418 to neck portion 414. Outlet 410 is defined by an inverted funnel portion 424 connected to neck portion 414 at the other end of neck portion 414. In some embodiments, outlet 410 is covered by seal 412 prior to use. In other embodiments, a seal or other type of pierceable partition is located in another portion of interior chamber 406 and / or interior chamber 406 includes a septum (e.g., similar to septum 300). Like interior chamber 206 of oral fluid container 200, interior chamber 406 provides a housing for toothbrush 100 when not in use. Additionally, the neck portion 414 (and / or in some embodiments the septum) is configured to remove excess oral fluid 204 from the toothbrush 100 (e.g., by pushing the excess oral fluid 204 out of the head 106 of the toothbrush 100 through a rubbing effect) when the toothbrush is removed from the internal chamber 406 for use.

[0024] The waste container 430 includes a funnel 416 and a receptacle 442 that holds toothpaste waste from a patient using the oral care system 480. The funnel 416 is connected to the receptacle 442 via a conical extension region 426. The funnel 416 provides a larger opening into which the patient can expel toothpaste waste while using the oral care system 480. The waste container 430 also includes an internal chamber 444 connected to the funnel 416 at a base 446 of the funnel 416 that facilitates the transfer of toothpaste waste from the funnel 416 to the receptacle 442. The internal chamber 444 includes an outlet 448 through which toothpaste waste passes and enters the receptacle 442.

[0025] In some embodiments, the drainage container 430 and the reservoir 403 are also sized to be spill-resistant, similar to the oral fluid container 200 described above. In some embodiments, the dimensions and / or dimensional ratios of the oral care system 480 are the same as the dimensions and / or dimensional ratios of similar components in the oral fluid container 200 (e.g., as shown in FIG. 3).

[0026] Referring now to FIG. 8 , a schematic side view of an oral-care system 580 according to another exemplary embodiment is shown. Oral-care system 580 includes a toothbrush, shown as toothbrush 100, and a unit-dose oral fluid container, shown as oral fluid container 500. In various arrangements, unit-dose oral fluid container 500 of FIG. 8 is substantially similar to unit-dose oral fluid container 200 of FIG. 2. As such, oral fluid container 500 is shaped similarly to oral fluid container 200 and includes a receptacle 502 and an internal chamber 506, and a funnel 516 in an interior portion of oral fluid container 500, similar to receptacle 202, internal chamber 206, and funnel 216 of oral fluid container 200. Receptacle 502 is connected to funnel 516 via a conical extension region 526. Additionally, similar to internal chamber 206, internal chamber 506 has an hourglass shape with an inlet 508 defined by a first chamber 518 coupled to a funnel 516, a second funnel portion 522 connecting first chamber 518 to a neck portion 514, and an inverted funnel portion 524 connecting neck portion 514 to a second chamber 520 defining an outlet 510. As such, in various arrangements, oral care system 580 may be used similarly to oral care system 280 described above.

[0027] Unlike oral fluid container 200, however, unit dose oral fluid container 500 includes an oral fluid cup 560 configured to serve as a reservoir for oral fluid 204. As such, in oral fluid container 200, oral fluid 204 is contained in oral fluid cup 560 instead of being in receptacle 502. In some embodiments, oral fluid cup 560 is coupled to unit dose oral fluid container 500. For example, oral fluid cup 560 is coupled to container 500 by an attachment mechanism (e.g., adhesive) or attachment device. Alternatively, oral fluid cup 560 is constructed as a unitary piece with container 500. In other embodiments, oral fluid cup 560 is sized to fit securely within unit dose oral fluid container 502, such as by a snap-fit ​​engagement.

[0028] Oral fluid cup 560 includes a base 562 that holds oral fluid 204. In the embodiment shown in FIG. 8, base 562 is cylindrical with a circular cross-section. However, in other embodiments, oral fluid cup 560 may have another cross-sectional shape, such as a cylinder or a square cylinder, or may have a varying diameter (e.g., conically shaped). A seal 512 extends across the top of base 562. In various arrangements, seal 512 is made of a plastic material, a foil material, or a similar material that can be punctured with little force. Seal 512 may span the entire diameter of receptacle 502, only base 562, or any portion therebetween. In the embodiment of FIG. 8, seal 512 of unit-dose oral fluid container 500 replaces seal 212 across outlet 210 of unit-dose oral fluid container 200. As such, to use oral care system 580, the patient must press toothbrush 100 against seal 512 with enough force that seal 512 breaks or is otherwise breached. In some cases, manufacturing a unit dose oral fluid container with an oral fluid cup having a seal (e.g., as described herein with respect to FIGS. 7, 8, and 10A and 10B) offers manufacturing advantages over unit dose oral fluid container 200 with seal 212. Alternatively, in other embodiments, oral fluid cup 560 may include a different pierceable partition, such as a cover with an internal cross cut.

[0029] Referring now to FIG. 9 , a schematic side view of an oral-care system 680 according to another exemplary embodiment is shown. Oral-care system 680 includes a toothbrush, shown as toothbrush 100, and a unit-dose oral fluid container, shown as oral fluid container 600. In various arrangements, unit-dose oral fluid container 600 is configured somewhat similarly or substantially similarly to unit-dose oral fluid container 200 shown in FIG. 2 . As such, oral fluid container 600 includes a receptacle 602 and a funnel 616 within the oral fluid container. Oral fluid container 600 also includes a chamber 606, although chamber 606 is configured differently from interior chamber 206 of oral fluid container 200. Specifically, chamber 606 of unit-dose oral fluid container 600 differs from the aforementioned interior chamber in that it does not have a neck portion with a reduced diameter. Instead, chamber 606 has a substantially cylindrical shape and a substantially uniform cross-section extending between inlet 608 and outlet 610. Inlet 608 provides a connection between funnel 616 and chamber 606, and outlet 610 provides a connection between chamber 606 and receptacle 602. The uniform cross-section of chamber 606, as well as the cross-sections of receptacle 602 and funnel 616, may be circular, oval, oblong, or any other shape that facilitates use of oral-care system 680.

[0030] 9 , chamber 606 has a portion that is within receptacle 602 and a portion that extends above receptacle 602. The portion of chamber 606 that extends above receptacle 602 is contained within a cylindrical neck portion 614. Cylindrical neck portion 614 is connected to and sized accordingly to a base 646 of a funnel 616, which also defines an inlet 608 to chamber 606. In addition, cylindrical neck portion 614 is connected to and sized accordingly to a top portion 638 of receptacle 602. In this manner, cylindrical neck portion 614 connects funnel 616 to receptacle 602, thereby allowing liquid to flow from funnel 616, through cylindrical neck portion 614, and into receptacle 602. As such, oral care system 680 may be used in a similar manner to oral care system 280 described above (e.g., by inserting toothbrush 100 through chamber 606 so that it is coated with oral fluid 204, removing the toothbrush from receptacle 602 for use, and dispensing into receptacle 602 via funnel 616).

[0031] In some embodiments, funnel 616, chamber 606, and receptacle 602 are fabricated as a single piece. In other embodiments, funnel 616, chamber 606, and / or receptacle 602 are fabricated as two or more pieces. For example, funnel 616 and chamber 606 are fabricated as a single piece that slides into top portion 638 of receptacle 602. Additionally, in various arrangements, receptacle 602 and top portion 638 are fabricated as a single piece or separate pieces. For example, receptacle 602 is fabricated as an open-topped column, and top portion 638 is configured to snap into the open top of receptacle 602.

[0032] Similar to unit dose oral fluid container 500, unit dose oral fluid container 600 also includes an oral fluid cup 660 configured to serve as a reservoir for oral fluid 204. As such, oral fluid 204 is contained within oral fluid cup 660 instead of being within receptacle 602. In various embodiments, oral fluid cup 660 is coupled to unit dose oral fluid container 600 as described above with respect to oral fluid cup 560 and unit dose oral fluid container 500. Oral fluid cup 660 includes a base 662 that holds oral fluid 204. In the embodiment of FIG. 9, base 662 is cylindrical with a circular cross-section. However, in other embodiments, base 662 may take on various cross-sectional shapes, such as a cylindrical or square cylinder, or may have a varying diameter (e.g., conically shaped). Further, in the embodiment of FIG. 9, oral fluid cup 660 is sized to hold 1-15 mL of oral fluid 204, such as oral fluid (e.g., sized to hold 7 mL of oral fluid 204).

[0033] As shown in FIG. 9 , seal 612 also extends across the top of base 662. In various arrangements, seal 612 is made of a plastic, foil, or similar material that can be pierced with little force. Like seal 512, seal 612 may span the entire diameter of receptacle 602, may span only the top of base 662, or may span any portion therebetween. In the embodiment of FIG. 9 , seal 612 of unit dose oral fluid container 600 replaces seal 212 across outlet 210 of unit dose oral fluid container 200. As such, to use oral-care system 680, the patient must press toothbrush 100 against seal 612 with enough force to cause seal 612 to break or rupture.

[0034] As shown, unit dose oral fluid cup 660 further includes a foam cover 666 positioned over seal 612. Foam cover 666 has an interior cross cut 668 extending therethrough. In some embodiments, foam cover 666 is a disk approximately 0.6 cm (0.25 inches) in height. In other embodiments, foam cover 666 has a height within a range of approximately 0.25-2.5 cm (0.1-1.0 inches). While foam cover 666 is described herein as being made of foam, in other embodiments, cover 666 may instead be made of a different material (e.g., rubber, sponge, etc.). When no force is applied, interior cross cut 668 of foam cover 666 remains in a closed position. However, interior cross cut 668 of foam cover 666 is configured to separate and thereby open foam cover 666 upon receiving a substantially perpendicular force in either direction, such as by a force provided by toothbrush 100. Thus, foam cover 666 couples to the top and / or receptacle 602 of oral fluid cup 660 and allows toothbrush 100 to pass through foam cover 666 into and out of oral fluid cup 660. In this manner, foam cover 666 serves as an additional penetrable barrier and provides additional protection against the spillage of oral fluid 204 from oral fluid cup 660, thereby increasing the spill resistance of oral fluid container 600 while maintaining an opening for toothbrush 100.

[0035] In use, as the toothbrush 100 passes through the internal cross cut 668 of the foam cover 666, the toothbrush is forced against and breaks or ruptures the seal 612, thereby allowing the toothbrush 100 to access the oral fluid 204. The toothbrush 100 is then removed from the oral fluid cup 660 through the internal cross cut 668 of the foam cover 666 for use. In some embodiments, the foam cover 666 also removes excess oral fluid 204 from the toothbrush head (e.g., by pushing and / or absorbing excess oral fluid 204 as the toothbrush 100 is pulled through the internal cross cut 668) as the toothbrush 100 is removed from the cup 660 through the foam cover 666. In some embodiments, the foam cover 666 further absorbs excess oral fluid 204 from the oral fluid cup 660, such as oral fluid 204 that comes into contact with the foam cover 666 by tipping or splashing along the walls of the oral fluid cup 660.

[0036] 10A and 10B, schematic side views of an oral-care system 780 according to another exemplary embodiment are shown. Oral-care system 780 includes a toothbrush, shown as toothbrush 100, and a unit-dose oral fluid container, shown as oral fluid container 700. FIG. 11A depicts a schematic side view of unit-dose oral fluid container 700, and FIG. 11B depicts a schematic top view of unit-dose oral fluid container 700, according to an exemplary embodiment. As shown in the figures, in various arrangements, unit-dose oral fluid container 700 is configured similarly to unit-dose oral fluid container 600 of FIG. 9. Accordingly, oral fluid container 700 includes a receptacle 702 defined by the interior of oral fluid container 700, a funnel 716, and a chamber 706 without a neck portion of reduced diameter. Instead, chamber 706, like chamber 606, has a substantially cylindrical shape and a substantially uniform cross-section extending between an inlet 708 and an outlet 710. Inlet 708 provides a connection between a funnel 716 and chamber 706, and outlet 710 provides a connection between chamber 706 and receptacle 702. The uniform cross-section of chamber 706, as well as the cross-sections of funnel 716 and receptacle 702, may be any shape that facilitates use of oral-care system 780, such as circular, oval, oblong, etc.

[0037] Further, similar to chamber 606 of oral fluid container 600, chamber 706 has a portion that is within receptacle 702 and a portion that extends above receptacle 702. The portion of chamber 706 that extends above receptacle 702 is contained within a cylindrical neck portion 714. Cylindrical neck portion 714 is connected to and sized accordingly to a base 746 of a funnel 716, which also defines an inlet 708 to chamber 706. In addition, cylindrical neck portion 714 is connected to and sized accordingly to a top opening 738 defined in an extension region of receptacle 702. Extension region 726 is conical in shape (e.g., like an inverted funnel) and connects a substantially constant diameter portion of receptacle 702 to chamber 706. In this manner, post-shaped neck portion 714 connects funnel 716 to receptacle 702, thereby allowing liquid to flow from funnel 716, through post-shaped neck portion 714, and into receptacle 702. Thus, referring back to FIGS. 10A and 10B , oral-care system 780 is used similarly to oral-care system 280 described above (e.g., by inserting toothbrush 100 through chamber 706 so that it is coated with oral fluid 204, removing the toothbrush from receptacle 702 for use, and dispensing it through funnel 716 into receptacle 702). Additionally, like unit-dose oral fluid container 600, oral fluid container 700 may be manufactured as a single piece or multiple pieces.

[0038] 10A and 10B , similar to unit dose oral fluid containers 500 and 600, unit dose oral fluid container 700 also includes an oral fluid cup 760 configured to serve as a reservoir for oral fluid 204. As such, oral fluid 204 is contained within oral fluid cup 760 instead of being within receptacle 702. In various arrangements, oral fluid cup 760 is coupled to unit dose oral fluid container 700 as described above with respect to oral fluid cup 560 and unit dose oral fluid container 500. Oral fluid cup 760 includes a base 762 that holds oral fluid 204. In the embodiment of FIGS. 10A and 10B , base 762 is cylindrical with a circular cross-section. However, in other embodiments, base 762 may take on various cross-sectional shapes, such as a cylindrical or square pillar, or may have a varying diameter (e.g., conically shaped). Additionally, in various arrangements, the oral fluid cup 760 is sized to hold 1-15 mL of oral fluid 204, such as oral fluid (e.g., sized to hold 7-7.5 mL of oral fluid 204).

[0039] 10A and 10B, a seal 712 also extends across the top of base 762, and in various embodiments, seal 712 is similar to seals 512 and / or 612 described above. Unit dose oral fluid container 700 further includes a sponge cover 766 having an internal cross cut 768 through the foam cover. In various embodiments, sponge cover 766 is configured and functions similarly to foam cover 666 described above with respect to unit dose oral fluid cup 660, except that sponge cover 766 is made of a sponge material rather than a foam material. However, in other arrangements, sponge cover 766 is made of a non-sponge material (e.g., rubber, foam, etc.).

[0040] Referring now to FIG. 12 , a schematic side view of an oral-care system 880 according to another exemplary embodiment is shown. Oral-care system 880 includes a unit-dose oral fluid container, shown as oral fluid container 800, and a toothbrush, shown as toothbrush 900. Referring to FIG. 13 , a side view of toothbrush 900 according to an exemplary embodiment is shown. Toothbrush 900 includes a handle 902 connected to a lower stem 904, which is connected to a head 906. Handle 902 includes an upper stem 908 from which a disk-shaped protrusion 910 extends. To provide an ergonomically beneficial design, the diameter of protrusion 910 varies along the length of upper stem 908. For example, protrusion 910 provides the toothbrush with a wider handle so that patients with reduced grip strength or ability can more comfortably grip the toothbrush. 13, in some embodiments, the protrusions 910 are wider near the bottom of the toothbrush 900 and narrower near where the lower stem 904 and upper stem 908 meet. As further shown in FIG. 13, in certain embodiments, the protrusions 910 are also narrower near the middle of the upper stem 908.

[0041] In various arrangements, the upper stem 908 is hollow to provide suction therethrough. Thus, as shown in FIG. 13 , the upper stem 908 includes a suction port 912 configured to couple to a suction mechanism. Additionally, the upper stem 908 includes a protruding suction opening 914. The protruding suction opening 914 is positioned so that a patient can place a finger over the opening to activate suction through the upper stem 908. The lower stem 904, which extends between the upper stem 908 and the head 906, is hollow to allow suction to pass between the head 906 and the suction port 912.

[0042] The head 906 includes bristles 916 and a foam section 918. In some embodiments, the foam section 918 is located on both the back and sides of the head 906. In other embodiments, the foam section 918 is located on only the back or sides. Furthermore, in some embodiments, the foam section 918 is glued to the head 906 of the toothbrush 900, while in other embodiments, the foam section 918 is attached to the head 906 through another mechanism (e.g., through an interference fit). As shown in FIG. 13 , in some embodiments, the foam section 918 has ridges to aid in cleansing. In various arrangements, the head 906 also includes at least one suction hole to allow for the suction of fluids (e.g., saliva, antiseptic, or other oral care fluids) from the user's mouth. The at least one suction hole is located on the top, front, and / or back of the head 906.

[0043] In various arrangements, toothbrush 900 is manufactured using cored-out injection molding. In some embodiments, toothbrush 900 is a single, integral injection molded piece forming upper stem 908, protrusion 910, lower stem 904, and head 906. In other embodiments, toothbrush 900 is manufactured in separate pieces and assembled to form the completed toothbrush 900. For example, upper stem 908 and lower stem 904 are formed together as a single injection molded piece, or are formed as separate pieces that are later connected together.

[0044] Toothbrush 900 is described herein with reference to oral-care system 880. However, it should be understood that toothbrush 900 may be used with any of the oral-care systems described herein. It should also be understood that oral-care system 880 may be used with toothbrushes of different designs, such as toothbrush 100.

[0045] As shown in FIG. 12 , with respect to oral care system 880, unit dose oral fluid container 800 includes oral fluid bottle 801 and cylinder solution cup 200. Referring now to FIGS. 14A and 14B , a schematic side view of oral fluid bottle 801 is shown according to an exemplary embodiment. Oral fluid bottle 801 includes receptacle 802, funnel 816 provided in the top portion of receptacle 802, and interior chamber 806 that provides a channel between the interior of receptacle 802 and funnel 816. As shown, receptacle 802 and interior chamber 806 are both contained within the interior portion of oral fluid bottle 801. Receptacle 802 is sized and configured to provide a stable base for oral fluid bottle 801. In the illustrated embodiment, the receptacle 802 of the oral fluid bottle 801 is cylindrical, however, in other embodiments, the receptacle 802 has another shape (eg, a rectangular base).

[0046] Funnel 816 is coupled to receptacle 802 at base 846 of funnel 816. Funnel 816 facilitates passage of toothpaste effluent to the interior portion of receptacle 802 during or after use of the toothbrush (e.g., toothbrush 900) by the patient. Funnel 816 provides a larger area for the patient to collect toothpaste effluent while brushing to minimize splattering associated with spitting into oral fluid bottle 801. As shown in FIGS. 14A and 14B , in some embodiments, funnel 816 is above the body of receptacle 802 and extends into receptacle 802 to form interior chamber 806. Interior chamber 806 thus includes second funnel portion 822 that narrows into neck portion 814. Liquid may be received into internal chamber 806 through inlet 808 at the top of second funnel portion 822 and may flow out of internal chamber 806 through outlet 810 at the bottom of neck portion 814. In certain embodiments, receptacle 802, funnel 816, and internal chamber 806 are also a unitary body integrally formed with one another. Oral fluid container 800 is configured to be used similarly to oral fluid container 200 described above (e.g., by inserting toothbrush 900 through internal chamber 806 to be coated with oral fluid 204, removing the toothbrush from receptacle 802 for use, and dispensing the toothbrush through funnel 816 into receptacle 802). Thus, in various arrangements, the internal chamber 806 is sized to hold a toothbrush head (e.g., toothbrush head 906), and the neck portion 814 is sized to force excess oral fluid 204 out of the toothbrush head 906 when the toothbrush 900 is removed from the oral fluid bottle 801 by pulling the toothbrush 900 through the internal chamber 806.

[0047] Additionally, receptacle 802 is configured to receive a cylinder solution cup through a lower portion of receptacle 802. As shown in FIGS. 14A and 14B , receptacle 802 has an open bottom for receiving the cylinder solution cup, however, in other embodiments, receptacle 802 is configured to receive the cylinder solution cup in a different manner (e.g., including a slot for sliding the cylinder solution cup into). In various embodiments, receptacle 802 also includes legs 872 that define an area for receiving the cylinder solution cup. Legs 872 are spaced apart to create opening 874 for facilitating insertion of the cylinder solution cup into receptacle 802. Receptacle 802 further includes holes 870 for locking the cylinder solution cup within receptacle 802. Holes 870 may have various arrangements on receptacle 802. For example, in some embodiments, and as shown in FIGS. 14A and 14B, the receptacle 802 includes two sets of two holes 870 opposite each other near the bottom portion of the receptacle 802.

[0048] 15 , a side perspective view of a spar solution cup 1000 according to an exemplary embodiment is shown. The spar solution cup 1000 includes a cup base 1002 configured to serve as a reservoir for oral fluid and receive toothbrushing waste from a patient while brushing their teeth. The spar solution cup 1000 is configured so that when the toothbrush 900 is immersed in oral fluid, the spar solution cup 1000 retains a sufficient amount of oral fluid to allow the head 906 of the toothbrush 900 to be substantially submerged in the oral fluid due to a change in the oral fluid volume caused by the displacement, while at the same time preventing the oral fluid from spilling out the top of the cup 1000. In some embodiments, the spar solution cup 1000 is configured to hold approximately 7.5 mL of oral fluid.

[0049] Cylinder solution cup 1000 includes a rim 1004 defining a ledge 1006 and having a cup protrusion 1008. Cup protrusion 1008 is spaced to align with hole 870 in oral fluid bottle 801 such that cup protrusion 1008 can snap into hole 870 to lock cylinder solution cup 1000 within receptacle 802 of oral fluid bottle 801. Cylinder solution cup 1000 also includes a top portion 1010 that is wider than cup base 1002. Top portion 1010 includes a gasket or O-ring 1014 that rides on ledge 1006 to provide a seal between cylinder solution cup 1000 and receptacle 802 once cylinder solution cup 1000 is snapped into oral fluid bottle 801.

[0050] The top portion 1010 defines an opening 1013 at the top of the spar solution cup 1000. The opening 1013 holds a cover 1012, which is shown in more detail in FIG. 16 . The cover 1012 may be constructed of foam, rubber, or a similar flexible material and includes an internal cross cut 1016. Similar to the internal cross cut 668 of the cover 666, the internal cross cut 1016 allows the toothbrush 900 to enter and exit the cover 1012 and removes excess oral fluid from the toothbrush head 906. The cover 1012 is glued or otherwise secured to the spar solution cup 1000 or rests over the spar solution cup 1000. In various embodiments, the spar solution cup 1000 includes a foil seal (not shown) beneath the cover 1012 to prevent oral fluid from leaking out of the spar solution cup 1000 prior to use. Thus, the level of oral fluid contained within cup base 1002 is selected to allow for easy sealing of cylinder solution cup 1000 without spilling the oral fluid. The seal is broken by pushing head 906 of toothbrush 900 through interior cross cut 1016 of cover 1012 and through the seal, if provided, after which head 906 of toothbrush 900 can be at least partially submerged in the oral fluid contained within cup base 1002. The seal and cover 1012 thus serve as a penetrable barrier through which toothbrush 900 must pass to access the oral fluid.

[0051] Referring back to FIG. 12 , an assembled oral care system 880 is shown. Accordingly, the spar solution cup 1000 is inserted into the oral fluid bottle 801 through the open bottom of the oral fluid bottle 801, as seen through the opening 874 between the legs 872. The spar solution cup 1000 also snaps into the unit dose oral fluid container 800 via the hole 870 and the cup protrusion 1008. The head 906 of the toothbrush 900 is seated within the neck portion 814 of the internal chamber 806. The neck portion 814 of the internal chamber 806 is sized to hold the head 906 of the toothbrush 900 securely in place, although the user may use a small amount of force to move the head 906 of the toothbrush 900 within the internal chamber 806 for use. For example, to use the oral care system 880, the patient pushes the head 906 of the toothbrush 900 through the outlet 810 of the internal chamber 806 and into the receptacle 802. The patient pushes the toothbrush 900 further into the cylinder solution cup 1000 by providing enough force to push through the cover 1012 and seal, if provided, of the cylinder solution cup 1000. The head 906 of the toothbrush 900 is then substantially covered with the oral fluid contained in the cup base 1002 of the cup 1000 and is removed from the receptacle 802 via the inlet 808 of the interior chamber 806. As shown in FIG. 12 , the rim 1004 fits snugly against the walls of the receptacle 802. Thus, the patient may spit into the receptacle 802 through the funnel 816, and the close fit between the cylinder solution cup 1000 and the receptacle 802 causes the toothbrush waste to be contained therein.

[0052] In some embodiments, oral fluid bottle 801 and prism solution cup 1000 are sized and shaped to provide a spill-resistant design, similar to unit dose oral fluid container 200 described above. Specifically, in various arrangements, receptacle 802, funnel 816, and internal chamber 806 are sized and configured based on the volume of oral fluid in the solution cup and / or the anticipated volume of toothpaste waste that will be received, such that even if receptacle 802 is tipped on its side, little or no fluid will flow into internal chamber 806 via outlet 810 and out of oral fluid bottle 801.

[0053] Referring now to FIG. 17 , a schematic perspective side view of an oral care system 1180 according to another exemplary embodiment is shown. Oral care system 1180 includes a unit-dose oral fluid container, shown as oral fluid container 1100, and a toothbrush, shown as toothbrush 1200. Additionally, as shown, unit-dose oral fluid container 1100 includes oral fluid bottle 1101, a cylindrical solution cup 1300, and a spit-out straw 1400. Referring to FIGS. 18A-18C , a side view of toothbrush 1200 according to an exemplary embodiment is shown. As shown, toothbrush 1200 is configured similarly to toothbrush 900 shown in FIG. 13 . Toothbrush 1200 includes a handle 1202 connected to a lower stem 1204, which is connected to a head 1206. Head 1206 includes bristles 1216 and a foam section 1218. The handle 1202 includes an upper stem 1208 with a disk-shaped protrusion 1210 extending from the upper stem 1208 .

[0054] Like protrusion 910, protrusion 1210 varies in diameter along the length of upper stem 1208 to provide an ergonomically beneficial design. However, unlike protrusion 910, the center of protrusion 1210 is offset from upper stem 1208 so that protrusion 1210 is larger in the direction of bristles 1216 than in the direction of foam section 1218 of head 1206 and extends past upper stem 1208 of handle 1202, as shown in FIG. 18B . Because protrusion 1210 is offset from upper stem 1208, toothbrush 1200 can be inserted into spit straw 1400, as shown in FIG. 17 , without crushing bristles 1216. Additionally, protrusion 1210 includes protrusion seal 1220 a and protrusion seal 1220 b. The protrusion seals 1220a and 1220b are configured to block the central conduit of the spit-and-receive straw 1400 to prevent contaminants (eg, dirt) from entering the interior of the oral fluid container 1100, as will be described in more detail below.

[0055] In various arrangements, the upper stem 1208 is hollow to provide suction therethrough. Thus, as shown in more detail in FIG. 18D , which shows a side perspective view of the toothbrush 1200, the upper stem 1208 includes a suction port 1212 configured to couple to a suction mechanism. Additionally, the upper stem 1208 includes a protruding suction opening 1214. The protruding suction opening 1214 is positioned and extends beyond the protrusion 1220 so that a patient can place a finger over the opening to activate suction through the upper stem 1208. The lower stem 1204, which extends between the upper stem 1208 and the head 1206, is hollow to allow suction to pass between the head 1206 and the suction port 1212.

[0056] As described above, head 1206 includes bristles 1216 and foam section 1218. As shown in FIG. 18E, which depicts a top perspective view of toothbrush 1200, in some embodiments, foam section 1218 is located on both the back and the sides of head 1206. In other embodiments, foam section 1218 is located on only the back or the sides of toothbrush head 1206. Furthermore, in some embodiments, foam section 1218 is glued to head 1206 of toothbrush 1200, while in other embodiments, foam section 1218 is attached to head 1206 through another mechanism (e.g., through an interference fit). As shown, in some embodiments, foam section 1218 has ridges to aid in cleansing. In various embodiments, head 1206 also includes one or more suction holes to allow for the suction of fluids (e.g., saliva, disinfectant, or other oral fluids) from the user's mouth. Suction holes are located on the top, front, and / or back of head 1206. In the embodiment shown in Figures 18A-18E, toothbrush 1200 includes suction hole 1222a formed laterally through the center of head 1206 and suction hole 1222b formed at the top end of the toothbrush.

[0057] Similar to toothbrush 900, in some embodiments, toothbrush 1200 is manufactured using hollowed-out injection molding. In other embodiments, toothbrush 1200 is manufactured in separate pieces and assembled to form finished toothbrush 1200. In addition, toothbrush 1200 is described herein with reference to oral-care system 1180. However, it should be understood that toothbrush 1200 may be used with any of the oral-care systems described herein. Furthermore, it should also be understood that oral-care system 1180 may be used with toothbrushes of different designs, such as toothbrush 100 or toothbrush 900.

[0058] 19A-19C, schematic side views of an oral fluid bottle 1101 according to an exemplary embodiment are shown. Oral fluid bottle 1101 includes a receptacle 1102 and an interior chamber 1106 defined within an interior portion of oral fluid bottle 1101, the interior chamber including outlet 1110. As shown in FIGS. 19A-19C, interior chamber 1106 includes a funnel portion 1122 that narrows to a neck portion 1114. Internal chamber 1106 thus provides a channel for receiving a spit-receiving straw 1400, as described in more detail below. Additionally, funnel portion 1122 provides additional spill resistance to oral fluid container 1100. In the illustrated embodiment, receptacle 1102 of oral fluid bottle 1101 is configured as a hollow cylinder, although in other embodiments, receptacle 1102 has another shape (e.g., a rectangular-bottom shape). Additionally, the oral fluid bottle 1101 is configured to be relatively tall compared to other components of the oral care system 1180 and to be wider from the top to the bottom of the oral fluid bottle 1101 to provide stability to the oral fluid bottle 1101.

[0059] The receptacle 1102 is configured to receive the cylinder solution cup 1300 through a lower portion of the receptacle 1102. As shown in FIG. 19A , the receptacle 1102 has an open bottom portion for receiving the cylinder solution cup 1300, however, in other embodiments, the receptacle 1102 is configured to receive the cylinder solution cup 1300 in a different manner (e.g., including a slot for sliding the cylinder solution cup 1300 into). In various embodiments, the receptacle 1102 includes holes 1170 for locking the cylinder solution cup 1400 within the receptacle 1102. The holes 1170 may have various arrangements on the receptacle 1102. For example, in some embodiments, the receptacle 1102 includes two sets of two holes 1170 facing each other near the bottom portion of the receptacle 1102.

[0060] 20A shows a schematic side perspective view of a squirt solution cup 1300, and FIGS. 20B and 20C show schematic side views of the squirt solution cup 1300, according to an exemplary embodiment. The squirt solution cup 1300 includes a base 1302 configured to serve as a reservoir for oral fluid and to receive toothpaste waste from a patient brushing their teeth. The base 1302 is configured to be wide enough to receive the end of a squirt straw 1400, as described in more detail below, and deep enough to allow the head 1206 of a toothbrush 1200 provided within the squirt straw 1400 to be at least partially submerged in the oral fluid contained within the base 1302. Additionally, prism solution cup 1300 is configured to hold a sufficient amount of oral fluid when toothbrush 1200 and spit-out straw 1400 are immersed in oral fluid such that a change in the volume of the oral fluid due to displacement volume allows head 1206 of toothbrush 1200 to be substantially submerged in the oral fluid, while at the same time preventing oral fluid from spilling out the top of cup 1300. In some embodiments, prism solution cup 1300 is configured to hold approximately 7.5 mL of oral fluid.

[0061] Cylinder solution cup 1300 includes rim 1304 defining ledge 1306 and having protrusion 1308. Protrusion 1308 is spaced to align with hole 1170 of oral fluid bottle 1101 such that protrusion 1308 can snap into hole 1170 to lock cylinder solution cup 1300 within receptacle 1102 of oral fluid bottle 1101. Additionally, rim 1304, and cylinder solution cup 1300 as a whole, are configured such that when protrusion 1308 snaps into hole 1170, receptacle 1102 of oral fluid bottle 1101 and rim 1304 of cylinder solution cup 1300 can contain liquid.

[0062] Additionally, cylinder solution cup includes legs 1318 that define an interior space into which base 1302 projects. Legs 1318 are spaced apart to provide a stable base for cylinder solution cup 1300, and also for the entire oral fluid container 1100 once cylinder solution cup 1300 is snapped into oral fluid bottle 1101. In the embodiment shown in FIGS. 20A-20C, cylinder solution cup 1300 has four legs 1318, however, cylinder solution cup 1300 may include any number of legs 1318 that provide a stable base.

[0063] The rim 1304 also defines an opening 1313 at the top of the cylinder solution cup 1300 that flows into the base 1302. In various embodiments, as shown in FIG. 20D , the opening 1313 is covered with a seal 1314. The seal 1314 is formed of foil, plastic, or other frangible material that can be pierced or broken. The seal 1314 is configured to contain the oral fluid inside the base 1302 until the oral-care system 1180 is to be used. However, as described in more detail below, the seal 1314 is also configured to be pierced, such as by being pierced by a spit-catching straw 1400, when a patient uses the oral-care system 1180. After the seal 1314 is pierced or broken, the head 1206 of the toothbrush 1200 is at least partially submerged in the oral fluid contained within the base 1302. Alternatively, in other embodiments, opening 1313 is sealed through another pierceable partition, such as a cover with a cross cut, similar to cover 1012 described above with respect to cylinder solution cup 1000.

[0064] 21A , a schematic side perspective view of a spit-collection straw 1400 is shown according to an exemplary embodiment. The spit-collection straw 1400 includes a funnel 1416 that connects at a base 1446 of the funnel 1416 to a tube 1490 having an opening 1492 at its end. The funnel 1416 and tube 1490 are configured to be inserted into the interior chamber 1106 of the oral fluid bottle 1101 such that the tube 1490 protrudes into the receptacle 1102. Thus, the spit-collection straw 1400 facilitates the passage of toothpaste waste to the interior portion of the receptacle 1102 during or after use of the toothbrush (e.g., toothbrush 1200) by the patient. The funnel 1416 provides a larger area for the patient to collect toothpaste waste while brushing to minimize splattering associated with spit-collection into the unit-dose oral fluid container 1100. The funnel 1416 and tube 1490 then direct the toothpaste waste through the inlet 1408 and opening 1492 of the spit-receiving straw 1400 and into the receptacle 1102. Additionally, the end of the spit-receiving straw 1400 is cut at an angle so that the plane of the opening 1492 is at an angle to the axis of the straw 1400. In this manner, the end of the straw at the opening 1492 has a leading edge that forms a cutting portion 1494 on one side. The cutting portion 1494 may be used to break or rupture the seal 1314 on the cylinder solution cup 1300 that snaps into the oral fluid bottle 1101.

[0065] 21B and 21C, side views of a spit-collection straw 1400 are shown according to an exemplary embodiment. As shown in FIGS. 21B and 21C, the base 1446 of the funnel includes a lip such that the base 1446 is wider than the top of the tube 1490 of the spit-collection straw 1400. Thus, the spit-collection straw 1400 is configured to receive the toothbrush 1200 within the central channel of the spit-collection straw 1400 formed within the funnel 1416 and the tube 1490, such that the protrusion seal 1220a rests on the base 1446, thereby sealing the assembled oral-care system 1180 from external contaminants. Additionally, the tube 1490 is sized to have a sufficiently wide diameter so that the protrusion seal 1220b fits snugly within it, further sealing the oral-care system 1180 from external contaminants. Furthermore, as shown, the tube 1490 includes a recess 1495. The recess 1495 is configured to be under the head 1206 of the toothbrush 1200 such that once the toothbrush 1200 is inserted into the tube 1490, a small force must be applied to remove the toothbrush 1200 from the spit-receiving straw 1400.

[0066] As shown in FIGS. 21A-21C, the tube 1490 of the spit-receiving straw 1400 also includes a protrusion 1496. The protrusion 1496 is angled to allow the spit-receiving straw 1400 to be inserted into the internal chamber 1106 of the oral fluid bottle 1101, but is configured to abut the outlet 1110 of the oral fluid bottle 1101 after insertion to prevent the spit-receiving straw 1400 from being pulled out of the internal chamber 1106. As such, the protrusion 1496 prevents the spit-receiving straw 1400 from being pulled out of the oral fluid container 1100 after insertion. In the embodiment shown in FIGS. 21A-21C, the spit-receiving straw 1400 includes two protrusions 1496, although in other embodiments the spit-receiving straw 1400 may include more protrusions 1496. Alternatively, in other embodiments, spit-receiving straw 1400, oral fluid bottle 1101, and / or cylinder solution cup 1300 may include different mechanisms to prevent spit-receiving straw 1400 from sliding out of oral fluid bottle 1101. In one example, spit-receiving straw 1400 includes a protrusion 1496 further down the length of tube 1490, and the top of cylinder solution cup 1300 includes a notch that engages with protrusion 1496. Thus, once spit-receiving straw 1400 is pressed into cup 1300, the engagement between protrusion 1496 and the notch prevents spit-receiving straw 1400 from being subsequently pulled out of cup 1300. In another example, the funnel 1416 includes a protrusion and the top of the oral fluid bottle 1101 includes a notch that engages with the protrusion so that once the spit-receiving straw 1400 is pushed far enough into the oral fluid bottle 1101, the notch engages the protrusion and the spit-receiving straw 1400 cannot be pulled back beyond the notch.

[0067] Additionally, spit-out straw 1400 includes holes 1498 formed in the sidewall of tube 1490 of spit-out straw 1400. Holes 1498 allow oral fluid container 1100, including oral fluid bottle 1101, cylinder solution cup 1300, and spit-out straw 1400, to be spill-resistant. For example, when oral fluid container 1100 is tipped over, liquid contained within receptacle 1102 (e.g., unused oral fluid, toothpaste waste) may flow into spit-out straw tube 1490 but may then flow out through holes 1498 in the sidewall of tube 1490 and back into receptacle 1102. Holes 1498 are designed to maximize the amount of liquid that can flow out of tube 1490 without compromising the structural integrity of tube 1490.

[0068] Referring back to FIG. 17 , an assembled oral care system 1180 is shown. Accordingly, cylinder solution cup 1300 is snapped into oral fluid bottle 1101 such that protrusion 1308 of cylinder solution cup 1300 fits within hole 1170 of oral fluid bottle 1101. Additionally, spit-out straw 1400 is inserted into internal chamber 1106 of oral fluid bottle 1101 such that protrusion 1496 prevents spit-out straw 1400 from being pulled out of oral fluid container 1100. As shown, in the embodiment of FIG. 17 , the components of oral fluid container 1100 (i.e., oral fluid bottle 1101, cylinder solution cup 1300, and spit-out straw 1400) are configured to have circular cross-sections, although in other embodiments, the components may have different cross-sections (e.g., oval, oblong).

[0069] 17, the toothbrush 1200 is also inserted into the tube 1490 of the spit-receiving straw 1400. The head 1206 of the toothbrush 1200 is positioned below the recess 1495 so that the toothbrush 1200 is held in the spit-receiving straw 1400 and a small force must be applied to remove the toothbrush 1200 from the spit-receiving straw 1400. Thus, the protrusion seal 1220a rests on the base 1446 of the spit-receiving straw 1400 and the protrusion seal 1220b seats on the inside of the tube 1490. The protrusion seals 1220a and 1220b together seal the interior of the oral-care system 1180 from external contaminants. Additionally, protrusion seal 1220a resting on base 1446 prevents toothbrush 1200 from sliding completely into tube 1490 and receptacle 1102. Similarly, protrusion seal 1220b fits snugly against tube 1490 such that the periphery of protrusion seal 1220b contacts the wall of tube 1490, further sealing oral fluid container 1100. Furthermore, protrusion 1220 is offset from the center of toothbrush 1200, allowing toothbrush 1200 to be inserted into spit straw 1400 without crushing bristles 1216 of toothbrush head 1206.

[0070] In some embodiments, oral care system 1180 is packaged as a pre-assembled unit, such as shown in FIG. 17 . In other embodiments, oral care system 1180 is packaged as separate components such that a user, such as a caregiver or patient, must assemble oral care system 1180 (e.g., oral fluid bottle 1101, toothbrush 1200, squirt solution cup 1300, and squirt straw 1400 are packaged separately). Additionally, the components of oral care system 1180 are made of any type of suitable material that is spill-resistant and hygienic. For example, in some embodiments, seal 1314 is made of polyethylene film, and squirt solution cup is a polyethylene cup. Additionally, oral fluid bottle 1101 and squirt straw are made of polypropylene.

[0071] 22A-22H, side views of the oral-care system 1180 are shown at various stages of use. First, FIGS. 22A and 22B show side views of the assembled oral-care system 1180 prior to use. As shown, the tip 1494 of the spit-receiving straw 1400 is adjacent to the seal 1314 of the cylinder solution cup 1300. Thus, to use the oral-care system 1180, the patient or caregiver pushes the toothbrush 1200 and / or the spit-receiving straw 1400, as shown by arrow 1182, until the tip 1494 of the spit-receiving straw 1400 breaks the seal 1314. In some embodiments, the spit-receiving straw 1400 may be moved approximately 0.64 cm (0.25 inches) within the receptacle 1102. Thus, the patient or caregiver may move the spit-receiving straw 1400 in a first direction to facilitate breaking, e.g., rupturing, the seal 1314, and then push the spit-receiving straw 1400 in the opposite direction toward the seal 1314.

[0072] The patient or caregiver then continues to push the toothbrush 1200 and / or spit-collection straw 1400 in the direction indicated by arrow 1184 so that the opening 1492 of the spit-collection straw 1400 and the head 1206 of the toothbrush 1200 are substantially submerged in the oral fluid contained within the base 1302 of the spit-collection cup 1300. The patient or caregiver pushes until the tip 1494 of the spit-collection straw 1400 is adjacent the bottom of the spit-collection cup 1300, as shown in FIGS. 22C and 22D . In doing so, the head 1206 of the toothbrush 1200 is substantially submerged in the oral fluid.

[0073] Once the toothbrush head 1206 is substantially submerged in the oral fluid, the patient or caregiver pulls the toothbrush 1200 and / or spit-receiver straw 1400 in the direction indicated by arrow 1186. Doing so withdraws the spit-receiver straw 1400 and the toothbrush 1200 contained therein. As shown in FIGS. 22E and 22F, the spit-receiver straw 1400 continues to be withdrawn until the protrusion 1496 on the tube 1490 of the spit-receiver straw 1400 contacts the outlet 1110 of the oral fluid container. The protrusion 1496 thus prevents the spit-receiver straw 1400 from being withdrawn further. At this time, the patient or caregiver continues to pull the toothbrush 1200 in the direction indicated by arrow 1188 until the head 1206 of the toothbrush 1200 slides past the recess 1495 and out of the spit-receiver straw 1400, as shown in FIG. 22G. In some embodiments, tube 1490 is configured to channel excess oral fluid from head 1206 of toothbrush 1200 as toothbrush 1200 is withdrawn from spit-out straw 1400. When toothbrush 1200 is removed from oral-care system 1180, spit-out straw 1400 descends back into oral fluid bottle 1101 and / or cylinder solution cup 1300, as shown in FIG. 22H. As such, a caregiver can easily check that the patient has used oral-care system 1180 by seeing whether spit-out straw 1400 is in its original position relative to oral fluid container 1100 or descends into the oral fluid bottle, as shown in FIG. 22H, indicating use.

[0074] Once the toothbrush 1200 is removed from the oral care system 1180, the patient may use the toothbrush 1200 in a standard manner to brush their teeth. The patient spits into the funnel 1416 of the spit-collecting straw 1400 to remove oral fluids from the mouth during or after brushing. Once the patient has completed the oral care procedure, the oral care system 1180 is disposed of. In some arrangements, the patient reinserts the toothbrush 1200 into the tube 1490 of the spit-collecting straw 1400 before disposing of the oral care system 1180.

[0075] Any of the oral care systems described herein, or another system combining a toothbrush (e.g., toothbrush 100, toothbrush 900, or toothbrush 1200) with a unit-dose oral fluid container (e.g., oral fluid container 200, 400, 500, 600, or 700; oral fluid container 800 including oral fluid bottle 801 and cylindrical solution cup 1000; or oral fluid container 1100 including oral fluid bottle 1101, cylindrical solution cup 1300, and spit-out straw 1400), may be packaged individually or as a kit containing three or four oral care systems. Thus, a care provider may leave the kit for a patient in the morning, and the patient will have the correct number of oral care systems to use that day. The caregiver may also check the oral care system for broken seals or toothbrush discharge to ensure patient compliance with the preferred oral care regimen, or, in the case of an oral care system that includes a spit-up straw, check that the spit-up straw is in the lowered post-use position into the oral fluid container. In some embodiments, the packaging may be designed with a small footprint for storage on a bedside table in a patient's room. In certain embodiments, the packaging further includes an element that covers or protects the funnel opening of the oral fluid container to minimize undesirable particles or materials from falling into the device and onto the toothbrush.
