SYSTEM, METHOD AND KIT FOR ORAL CARE

Field of the Invention

Embodiments of the present invention relate to methods, systems and kits for performing and/or monitoring oral care.

BACKGROUND

Figures 1A-1D show oral care kits for performing a multi-treatment oral care cycle.

Fig. 1A is taken from United States Patent 7,866,477. United States Patent 7,866,477 discloses an oral care kit comprising a substantially rectangular box having oral care packs positioned therein. The oral care packs contain oral care devices useful for administering oral care treatment during a 24 hour oral care treatment cycle. The packs are useful for treating intubated patients in the hospital intensive care unit (ICU). As shown in Fig. 1A, the rectangular box comprises a plurality of partitions, each of which stores a different oral care pack. Not all of the packs stored in the partitions are identical. In one example, the number of toothbrush packs, catheter packs, suction swab packs with hydrogen peroxide, and suction swab packs with alcohol free mouthwash is 2:2:4:6, respectively.

The fact that each compartment may store a different type of oral care pack allows the user (e.g. a nurse in an ICU) to keep track of the different types of oral-care treatments, and in particular to apply the correct number of treatments in the correct ratio.

One feature of the oral care kit of United States Patent 7,866,477 is the need to employ the internally portioned box. For example, the cost of packaging increases to the overall cost of the oral care. In addition, each box occupies space within the ICU, a location where space is at a premium. However, as noted above, the internally portioned box is indeed useful, as it allows a caregiver (e.g. ICU nurse) to easily track the number of each type of oral-care treatment previously applied to a patient, in order to apply the different types of oral-care treatments in the appropriate and pre-determined order. Fig. 1A, taken from United States Patent Publication 20110155612 shows another example of an oral care kit.

Additional prior art examples of oral care kits (i.e. from Sage Products) are shown in Figs. 1C-1D. As shown in Fig. 1C-1D, the oral care kit comprises a plurality of packs (3 individual packs are shown in each of Figs. 1C and ID - each pack is sealed. Upon opening each pack, the pack is opened irreversibly and the seal is broken irreversibly.

Within each pack of the kits of Figs. 1C-1D, is a sponged-rod (e.g. see Figs,. 2A- 2B) and a lumened' toothbrush-suction hybrid device' or 'suction-lumened-toothbrush' (see Figs. 3A-3D).

The device in Fig. 2B is labelled 1206 - -it is a rodded oral-cleaning device (e.g. having a suction lumen) that has sponge but lacks toothbrush bristles. Other examples, not in the prior art but according to some embodiments, of a device which can be labelled 1206 are discussed below.

liquid-absorbing material (e.g. sponge material) In the example of Fig. 3C, the suction-lumened toothbrush includes (i) a proximal connector 964 (e.g. tapered) at the proximal end of the suction lumen and (ii) a distal suction orifice 968 the distal end of the suction lumen.

The device shown in Figs. 3A-3C is both a (i) 'sponged-rod' and (ii) a lumened' toothbrush-suction hybrid device' or 'suction-lumened-toothbrush. In contrast, the device of proximal connector 964 is connected to a source of negative suction 200, negative pressure is transmitted via an interior of the suction lumen to space outside of the suction orifice. This is useful for suctioning matter (e.g. biofilm, or liquids or any other matter) out of the subject's mouth during oral care treatment - e.g. during a toothbrushing session. In contrast, the device of Fig. 3D is only a lumened' toothbrush- suction hybrid device' or 'suction-lumened-toothbrush - the device of Fig. 3D is not a sponged rod device.

A sponged rod device (e.g. see Figs. 2A-2B or 3A-3C but not Fig. 3D) is typically used for 'soft tissue lubrication' operations. A soft tissue lubrication is performed by a caregiver (e.g. nurse) upon a human subject (e.g. intubated patient in the ICU) and is characterized primarily by lubricating contact between the sponge 954 (e.g. which may hold a cleaning fluid - e.g. comprising a disinfectant) and soft tissue (e.g. lips, gums) of the human subject's mouth - optionally, there may be a certain minimal amount of brushing of the subject's teeth, but the dominant mode of operation during a soft tissue lubrication is to lubricate soft-tissue of the patient's mouth rather than brushing the subject's teeth. Optionally, during soft tissue lubrication sessions matter is suctioned from the subject's mouth.

A lumened' toothbrush- suction hybrid device' or 'suction-lumened-toothbrush (e.g. see Figs. 3A-3D but not Figs. 2A-2B) is typically used for 'toothbrushing' operations. During a 'toothbrushing session,' brushing of the subject's teeth is the dominant mode of operation - optionally, there may be a certain minimal amount of lubrication of soft tissue of the subject's mouth, but the dominant mode of operation during a toothbrushing session is to brush the subject's teeth rather than to lubricate soft- tissue of the patient's mouth rather. Another required feature of toothbrushing sessions is suctioning of matter from the subject's mouth by applying a suction source to a suction lumen so that matter (i.e. driven by negative pressure in the suction lumen and from the suction source) while the subject's teeth are brushed.

As shown in Figs. 1A-1D, each package (e.g. sealed packaged or oral care apparatus between two partitioned) has a pre-determined number of each type of device. To perform an oral care cycle, a caregiver first opens a first packages having a predetermined count of each type of device and uses every oral care device within the first package. Then the caregiver opens a second packages having a predetermined count (i.e. the same count or different counts) of each type of device. And so on.

Because the caregiver will typically use each oral care device sequentially and only for one session, it is possible for manufacturers to help caregivers comply with a specific oral care cycle by including the correct number of each type of oral care device within each individual package - in the example of Figs. 1B-1C there are three such packages.

There is an ongoing need for systems and methods which facilitate oral care in the ICU at a reduced cost and/or in a manner that reduces the amount of space required in the ICU. The following issued patents and patent publications provide potentially relevant background material, and are all incorporated by reference in their entirety: US6186782, , US6766548, US6920659, US8453285, US 20110155612 and US 7,866,477. Any feature or combination of features disclosed in any of the aforementioned prior art documents may be combined with any feature disclosed herein.

As noted above, the device shown in Figs. 3A-3C is both a (i) 'sponged-rod' and (ii) a lumened' toothbrush-suction hybrid device' or 'suction-lumened-toothbrush. Fig. 4A shows another view of this device - the sponge 954 is on one side of the rod assembly 960 (i.e. facing in the rear-facing direction) while the toothbrush-bristle brush 948 is on the other side of rod assembly 960 (ie.. in the front-facing direction 942). The central axis 938 of Fig. 4Ais the central axis of rod assembly 960 (or of the suction lumen within or alongside rod assembly 960) for locaotin where the toothbrush bristles are present.

Fig. 4A is a side view. Fig. 4B-4C are both top viewa (i.e. looking down on suction lumen 968) and a schematic view - once again, the sponge 954 is on one side of the rod assembly 960 (i.e. facing in the rear-facing direction) while the toothbrush-bristle brush 948 is on the other side of rod assembly 960 (ie.. in the front-facing direction 942).

SUMMARY OF EMBODIMENTS

Embodiments of the invention relate to a method, kit and apparatus for facilitating the cleaning oral cavity and/or teeth of a subject, including but not limited to an intubated subject.

In some embodiments, the method, kit or apparatus provide a modular device (e.g. comprising a base module having an onboard reservoir and a head module that is s toothbrush - e.g. a suction-lumened-toothbrush ) which, when assembled, first and second one-way valves facilitate loading and unloading of a fluid reservoir, containing a cleaning fluid. With reference to Figs. 6A-6C, 7, 8A-8B, 9A-9B a novel mechanism for loading the fluid reservoir and unloading the reservoir is shown to introduce fluid into the mouth (e.g. a delivering a stream of fluid). In some embodiments, this mechanism provides for repeated and easy loading and unloading of a reusable fluid reservoir, obviating the need for sachets of cleaning fluid, reducing the cost of kits and/or packaging thereof.

Alternatively or additionally, in order to facilitating tracking of oral care operations in a manner that minimizes the need or use of packaging (thereby minimizing costs), a non-electronic multi-input multi-display counter 149 (e.g. mounted to the substrate board or to the base module) is now disclosed. The multi-input/multi-display counter independently displaying first and second count- states, the multi-input multi- display counter including first and second independently-operable user inputs respectively associated with the first and second count states such that: (I) in response to user engagement of the first user input, the first count state is incremented or decremented; and (II) in response to user engagement of the second user input, the second count state is incremented or decremented. As will be discussed below, this counter may be used to track different types of oral care operations.

During operation, the head and base modules are attached (i.e. directly or indirectly attached) to each other to form a head-base assembly.. In particular, (i) the base module may mechanically supports the head module (e.g. lumened toothbrush), and serves as a handle via which the user applies force to brush the subject's teeth using the head-module-disposed brush; (ii) fluid (e.g. cleaning fluid - e.g. loaded as described in Figs. 6B and/or 8B) is expelled (e.g. as shown in Figs. 6C and/or 9B) from the base- module-disposed fluid container, forced through a fluid delivery lumen (e.g. constructed of 124 and 214), and enters the subject's mouth (e.g. as a jet) via a fluid delivery lumen, e.g. disposed at or near the brush; and (iii) optionally but in some embodiments preferably, matter is suctioned out of the subject's mouth (e.g. via suction lumen sections 160 and 370 which form a continuous suction lumen), where the suction is applied through a proximal suction port or connector (e.g. tapered connector 171) and communicated to a distal suction orifice via a suction lumen. The matter is suctioned out of the subject's mouth via the distal suction orifice.

Similar to the situation of United States Patent 7,866,477, the subject (e.g. intubated patient in the ICU) may be subjected to a variety (e.g. at least two different types) of oral care treatments, one of which is the aforementioned toothbrushing treatment described in the previous paragraph. In addition, during his/her stay in the ICU, the same subject may also be subjected to other types of treatment, for example, a mouth- moisturizing treatment wherever a mouth moisturizer is applied to the gums - for example, the mouth-moisturizing treatment may be applied more frequently than the tooth-brushing treatments. Over a period of several days, subjects/patients are commonly subjected to a repeated 24 hours cycle of oral cleaning. For reducing the risk of contamination, it is typical required that the brush-comprising components will be used only once and then disposed of. Prior art broke down the oral care kits into two type of components - single use heads and 24h hours base handles. The 24h cycle usage was recorded by the depletion of pre-ordered set packages.

In contrast, the present inventors recognize an advantage for breaking down the oral care kits into two types of components - short-use heads (e.g., single use), and more extended-use (e.g., more than a week) base handles. The 24h cycle recording is then maintained by counters disposed on the base (e.g. see Figs. 5D, 5E (left), 7, 8A-8B, 9A- 9B) or on a substrate board (e.g. see Figs. 10-11, 13A-13F.16A-16E and 17A-17B) , where the counters are (optionally but in embodiments preferably) to be reset to zero - for example, by the user (e.g. nurse) after each 24h day term.

As will be discussed below, the base module (which includes the multi- input/multi-display counter) is typically used for a longer period of time than either the head or tail modules. In one non-limiting example, the head module is single-use (e.g. per toothbrushing session), the base module is used for a much more extended period of time (e.g. per patient, for example, a week or more).

Preferably, the counter is not electronic.

In one particular user-case related to the less-preferred example of electronic counters, a single base module and/or a substrate board remains bed-side for each patient during his/her entire stay in the ICU, and the multi-input/multi-display counter comprises two miniature (e.g. 2 cm X 2 cm) electronic display- screens (e.g. liquid crystal display (LCD) screens) mounted side-by-side (i.e. next to each other) onto the base module. Each display-screen is respectively associated with respective 'increment' button mounted immediately below the display screen. Thus, the multi-input/multi-display counter comprises two user inputs - the 'increment' button directly beneath the left display- screen is the first user input and the 'increment' button directly beneath the right display- screen is the second user input.

In this less-preferred 'electronic counter embodiments,' upon start-up (i.e. power- on) each electronic display screen displays '0' - whenever the 'increment' button is pushed this increments the number displayed by the electronic display screen directly above the pushed 'increment' button (i.e. from 0 to 1 after a single depression of the increment button, from 1 to 2 the next time the increment button is pressed, and so one). At any given time, each electronic display screen displays a respective display integer displaying the number of times its respective/associated increment button was previously pushed. Thus, the multi-input/multi-display counter defines two 'count-states' - the integer displayed by the 'left' electronic display screen is the first count- state and the integer displayed by the 'right' electronic display screen is the second count-state.

Because the base module or substrate board (i.e. on which the counter is disposed) remains bed-side during an entirety of the patient's stay in the ICU, the base module or substrate board is a useful location for the multi-input/multi-display counter.

In particular, in particular examples, whenever the ICU patient is subjected to a first type of treatment (i.e. tooth brushing treatment), the care-giver manually engages the first user-input (i.e. by depressing the increment button beneath the left display screen) - this increments the first count-state (i.e. the integer on the left display screen - i.e. from 0 to 1, from 1 to 2, and so on). Whenever the ICU patient is subjected to a second type of treatment (e.g. mouth-moisturizing treatment), the care-giver manually engages the second user-input (i.e by depressing the increment button beneath the right display screen) - this increments the second count-state (i.e. the integer on the right display screen - i.e. from 0 to 1, from 1 to 2, and so on).

In the less-preferred example of electronic counters, each screen displays its respective display screen, which is visible to anyone who wishes to read the 'count-state' afterwards (e.g. the same nurse, or another nurse from the next shift).

In this manner, at any given time any nurse in the ICU may read from the base- module-disposed counter the number of previous treatments of the first and second types to which the intubated patient has previously been subjected. The nurse will read the base -mode and know the number of previous toothbrush-treatments and the number of previous mouth-moisturizing treatments - this will help the nurse decide if the next treatment to the intubated patient will be a toothbrush treatment or a mouth moisturizing treatment. Since the base and/or substrate board (e.g. having containers or holders mounted thereto) is re-used for different toothbrushing sessions and remains by the patient's bedside during an entirety of his/her stay in the ICU, this information (i.e. about the previous number of treatments of the first and second types) is readily available to any nurse in the ICU.

Since this information about the absolute and relative numbers of previous treatment of each type is readily available, there is no need to individually provide different types of oral care packs within compartments of a multi-compartment packaging, such as that disclosed in United States Patent 7,866,477.

Thus, in some embodiments, the presently-disclosed teachings allow for the hospital to do away completely with per-patient oral-care kits of the type disclosed in United States Patent 7,866,477. Instead, it is possible to employ a much more 'primitive' (but cheaper and less space-consuming) packaging where the oral care packs are stored in bins or bags - for example, bag or bin "A" includes only oral care packs of the first type, bag or bin "B" includes only oral care packs of the second type, and so on.

When a nurse approaches a given patient, s/he can check the base module disposed near the patient's bed to read, from the base-module-disposed counter, the number of previous treatments of each type applied to the patient. As such, the nurse can instantly ascertain the next type of oral-care treatment required in the oral care cleaning cycle, take the appropriate oral care element(s) (e.g. in a treatment pack) from the appropriate bag (e.g. bag or bin 'A' or bag or bin 'Β'), and subjects the patient to this oral-care cleaning procedure using the oral care element(s) obtained from the appropriate bag. If appropriate (e.g. if the oral-care cleaning procedure involves brushing the patient's teeth), this oral care procedure may be performed using the base module as a toothbrush handle.

After performing a particular type of treatment, the nurse simply increments the counter appropriately. Thus, for treatments of type 'A' (e.g. using cleaning elements(s) from bag or bin Ά') the base-module-disposed multi-input/multi-display counter is operated to increment a first count-state (e.g. to depress the button directly beneath the left display screen to increment its display integer). For treatments of type 'B' (e.g. using cleaning elements(s) from bag or bin 'B') the base-module-disposed counter is operated to increment a second count-state (e.g. to depress the button directly beneath the left display screen to increment its display integer).

DETAILED DESCRIPTION OF EMBODIMENTS

Embodiments of the present invention relate to a rodded oral care device which may be (i) a toothbrush device having an onboard toothbrush (e.g. plurality or field of bristles) (e.g. suction-lumened-toothbrush) or a (ii) fluid applicator device (e.g. having a fluid-delivery lumen through which fluid is actively forced into the mouth or a more 'passive' fluid applicator device such as a sponged rod or a swab device).

Embodiments of the present invention relate to systems, methods and kits for cleaning the oral cavity and/or teeth of a subject, including but not limited to an intubated subject.

The invention is herein described, by way of example only, with reference to the accompanying drawings. With specific reference now to the drawings in detail, it is stressed that the particulars shown are by way of example and for purposes of illustrative discussion of the preferred embodiments of the exemplary system only and are presented in the cause of providing what is believed to be a useful and readily understood description of the principles and conceptual aspects of the invention. In this regard, no attempt is made to show structural details of the invention in more detail than is necessary for a fundamental understanding of the invention, the description taken with the drawings making apparent to those skilled in the art how several forms of the invention may be embodied in practice and how to make and use the embodiments. For brevity, some explicit combinations of various features are not explicitly illustrated in the figures and/or described. It is now disclosed that any combination of the method or device features disclosed herein can be combined in any manner - including any combination of features - any combination of features can be included in any embodiment and/or omitted from any embodiments. For the present disclosure, 'attachment' refers to direct or indirect attachment via attaching element(s) of the system or kit. When two modules are attached via an 'attachment element' the attachment element either be inherent to any of the modules (i.e. base, tail or head module) or could be an 'external element' that is external to the two modules and provided as part of a given system or kit. For example, the 'external element' may be part of a third module or may be any other external element. The external element may bridge between respective locations of each of the two attached modules. Examples of 'attachment elements' include but are not limited to fasteners, snaps, screw elements, spring-activated attachment elements, clamps, and magnetic attachment elements.

For the present disclosure, when a first module is 'distal' to a second module, that means the first module as a whole may be considered 'distal' to the second module, even if portions of the 'first' module are proximal to portions of the second module. This is illustrated in Figs. 1-2 where the head module 150 is 'distal' to both the base module 110 and the tail 151 module.

Reference is made to Fig.5A, which illustrates elements which illustrates an oral care system for brushing a patient's teeth and for monitoring different types of oral care operations. The oral care system is modular - in particular, is assembled from two modules : base module 100 (which optionally may be disassembled into multiple modules - see Fig. 5E), head module 150. In some embodiments, base module 100 includes (e.g. disposed on a main body of base module) a multi-input/multi-display counter 149 for tracking different types of oral care operations. In alternate embodiments (see, e.g. Fig. 10) multi-input/multi- display counter 149 is on a substrate board.

When used for toothbrushing, the oral care device of Fig. 5A is capable of simultaneously performing three operations - (i) a toothbrushing operating using toothbrush-bristle brush 165; (ii) a suction operation whereby matter (e.g. debris or biofilm) is suctioned into and through a suction lumen 170 (NOT SHOWN in Fig. 5A) via suction orifice 172- towards this end, suction lumen 170 is attached to a source of negative pressure (NOT SHOWN) via a proximal end thereof (e.g. via suction connector 171 which is preferably tapered); and (iii) a fluid-delivery operation whereby fluid stored within container 120 is expelled therefrom, travels through fluid-delivery lumen 214 (NOT SHOWN in Fig. 5A) and exits therefrom via distal fluid delivery orifice 218.

Fig.5G shows these operations performed simultaneously.

Also visible in Fig. 5 A is sheath 179 - this element may be used in embodiments where the toothbrush is a 'power brush' vibrations are transmitted from the base module 100 to the toothbrush 160 via a cavity (NOT SHOWN in Fig. 1 - this is element 177) of sheath 179 which is part of head module 150.

Also illustrated in Fig. 5A is a longitudinal axis 196, a distal direction 192 and a proximal direction 194.

In addition, in the intensive care unit (ICU), multiple type of oral care operations are performed (e.g. by members of the nursing staff) on a single patient. In one example, a mouth moisturizing operation is performed relatively frequently (e.g. every few hours), while a tooth brushing operation is performed somewhat less frequently. During this time, the base module 100 would remain by the patient's bed.

As will be discussed below in greater detail, in some embodiments, base module 100 includes (e.g. disposed on a main body of base module) a multi-input/multi-display counter 149. In the non-limiting example of the figures, multi-input/multi-display counter 149 is mechanical and comprises first and second user-input. For example, the inputs are first 145 and second 146 manually-rotatable pointers. In this example, the multi-input/multi-display counter 149 comprises first 143 and second 144 visualization elements - for example, first and second pluralities of ticks. The first plurality of ticks 143 is disposed around a center of rotation of the first 145 rotatable pointer. The second plurality of ticks 144 is disposed around a center of rotation of the second 146 rotatable pointer.

The multi-input/multi-display counter 149 independently displays first and second count-states. In the particular example of the drawings, the first count-state is the relative position of first rotatable pointer 145 relative to the first plurality of ticks 143, and the second count-state is the relative position of second rotatable pointer 146 relative to the second plurality of ticks 144.

Furthermore, multi-input/multi-display counter 149 includes first and second independently-operable user inputs (in this non-limiting example, the first 145 and second 146 rotatable pointer which rotate around different centers) that are respectively associated with the first and second count-states (in this example, the relative positions of the pointers with respect to the ticks respectively define ).

Multi-input/multi-display counter 149 further provides the following feature - in response to user engagement (e.g. manual rotation of rotatable pointer 145 from one marker/tick to its neighbor)) of the first user input (i.e .the rotatable pointer 145), the first count state (e.g. the angular position of pointer 145 relative to its set of ticks 143) is incremented or decremented. For example, rotation in one direction to transition the pointer 145 orientation between neighboring ticks (e.g. from a first tick (i.e. of the set of ticks 143) to a neighboring tick that is to the right of the first tick) will serve to increment the count, and rotation in the opposite direction (i.e. counterclockwise) from a the first tick to a neighboring tick that is to the will serve to decrement the count.

Multi-input/multi-display counter 149 further provides the following feature - in response to user engagement (e.g. rotation of pointer 146)) of the second user input (i.e. the rotatable pointer 146), the second count state (e.g. the position of pointer 146 relative to its set of ticks 144) is incremented or decremented. For example, rotation in one direction to transition the orientation of rotatable pointer 145 between neighboring ticks (e.g. from one tick of the second set of ticks 144 to a neighboring tick of the second set of ticks 144) will serve to increment the count, and rotation in the opposite direction will serve to decrement the count.

The term 'multi-input' means the counter 149 has two inputs - in the example of Fig. 3 pointer 145 is the first input and pointer 146 is the second input.

The term 'multi-display' means the counter is able to independently display (i) a first count-state (i.e. defined by the orientation of pointer 145 relative to the ticks 143 - i.e. which specific and discrete tick (of the ticks 143) pointer 145 is pointing to) and (ii) and a second count-state (i.e. defined by the orientation of pointer 146 relative to the ticks 144 - i.e. which specific and discrete tick (of the ticks 144) pointer 146 is pointing to.

One example of 'incrementing' a count state is shown in Fig. 15 - in this example, the 'user input' is the single rotatable pointer which is engaged by manual rotation and responds to the manual rotation by moving from one tick to its neighbor, thereby incrementing the displayed count-state.

Also shown in Fig. 5 A is a mechanical switch 140 - for example, the oral care device may include an electrical power brush, and switch 140 serves to turn on or off the brush. As will be discussed below, in some embodiments head module base module comprises a distal-protruding portion of base module main body 110 within which a rotating eccentric mass causes vibrations which are transmitted to brush 165. For example, distal-producing portion may be received into a proximal-facing cavity of sheath element 179. Thus, sheath element 179 shown in Fig. 5A may be provided for power-brush embodiments. In other embodiments, the device functions as a 'manual toothbrush' with having no motor.

Figs. 5B-5F show other examples.

Figs. 5G-5H show simultaneous suction and fluid-delivery.

Figs. 6-9 relate to an example of loading fluid into a reservoir 120 while the base and head (e.g. suctioned lumen) are assembled. This may obviate the need for removable single-use fluid sachets, reducing the cost of packaging of oral care products.

Fig. 6A and 8A shows the situation before loading - reservoir 120 is compressed. In Figs.6B and 8B, expansion of the reservoir 120 causes loading thereof - e.g. by a negative pressure in reservoir 120. As shown in Fig. 8B, a presence of one-way valve 324 creates a barrier so that no fluid may flow proximally via fluid delivery section 214 back into reservoir 210.

In Figs.6C and 9B, expansion of the reservoir 120 causes loading thereof - e.g. by a negative pressure in reservoir 120. As shown in Fig. 9B, a presence of one-way valve 323 creates a barrier. In Figs. 8B and 9B, the shading shows a presence of fluid (e.g. or flow thereof).

Some embodiments of the invention relate to an oral care kit comprising:

a. a base module comprising a non-electronic multi-input/multi-display counter disposed on or mounted to the base-module, the base module further comprising: i. an onboard compressible fluid reservoir 120 having an equilibrium size so that, when released from a compressed configuration, a restoration force urges size-increase of the reservoir 120 back to the equilibrium size; ii. an onboard inlet tube 311 leading into the compressible fluid reservoir for loading thereof; iii. a first one-way valve 323 disposed in the inlet tube 311 to permit fluid inflow past the first one-way valve towards the fluid reservoir and to block fluid backflow from the reservoir in the opposite direction; iv. a base- module-onboard fluid-delivery lumen section 124; v. a second one-way valve 324 disposed in the onboard fluid-delivery section to permit fluid outflow of fluid flowing from the reservoir past the second one-way valve and to block fluid backflow towards the reservoir in the opposite direction; vi. a base-module onboard suction lumen section 370 that does not lead into the fluid compressible reservoir 120; b. a plurality of rodded oral care devices, at least one of which is a suction-lumened-toothbrush including an onboard head-module-onboard suction lumen section 160, an onboard fluid-delivery-lumen section having a fluid-delivery-orifice 218 at a distal end of the head-module-onboard fluid-delivery-lumen section 214, and a plurality of toothbrush bristles; d. a substrate board including a hanger; and e. a storage compartment array (e.g. 936 A or 936B or 936B of FIG. 10) of one or more storage compartments mounted to the substrate board, the storage compartments, the hanger and the substrate board collectively configured to hold and support both the base module and each rodded oral care device of the plurality of rodded oral care devices, wherein: i. the suction-lumened toothbrush is detachably attachable to the base module to form an oral care device so that upon attachment: A. the respective suction lumen sections 160, 370 form a continuous suction lumen along a length of oral care device; and B. the respective fluid-delivery sections 214, 124 form a continuous fluid-delivery lumen that provides fluid communication between an interior of the fluid reservoir and the fluid-delivery orifice; ii. after attachment, expansion of the fluid reservoir from an at-least partially compressed configuration loads the fluid reservoir 120 so that a negative pressure created within the expanding reservoir suctions fluid past the first one-way valve into the fluid reservoir while a presence of the second one-way valve blocks back-flow into the fluid reservoir through the base-module- onboard fluid-delivery lumen section 124; iii. after attachment and after loading, compression of the fluid reservoir unloads the fluid reservoir to force the unloaded fluid to exit the fluid-delivery orifice so that outflow from the fluid reservoir flows through the continuous fluid-delivery lumen formed by the attachment and past the second 324 oneway valve while a presence of the first one-way valve 323 prevents flow of backflow into the fluid reservoir through the inlet tube 311 and past the first one-way valve; and iv. the multi-input/multi-display counter is configured to independently display first and second count-states, the multi-input multi-display counter including first and second independently-operable user inputs respectively associated with the first and second count states such that: (I) in response to user engagement of the first user input, the first count state is incremented or decremented; and (II) in response to user engagement of the second user input, the second count state is incremented or decremented; and

Figs. 10 and 11 shows hangable system having (i) hanger 998 , (ii) multi display/multi input counter 149 comprising first 147A and second 147B single-input counters and (iii) a plurality of storage shelfs 936A-936. Fig. 12 illustrates use of a multi display/multi input counter 149 and is identical to Fig. 24B discussed below.

As shown in Fig. 11, in some embodiments the kit and/or system comprises at least one or ar least two or at least three suction members 777 (in fig. 11 three are shown - 777A- 777C) are included in the kit and/or system.

In some embodiments, each suction member 777 (e.g. without toothbrush bristles attached to the suction member 777) comprises a flexible tube having at least 90 degrees or at least 105 degrees or at least 120 degrees or at least 135 degrees or at leasty 150 degfees of bending freedom and capable of stustaining its bend angle without external sustaining forces -e.g. bending tube (e.g. rubber and/or plastic — biocompatible) comprising pliable (but not pliable) metal stiffening element (NOT SHOWN) disposed in an interior of the tube.

Figs. 13A-13B illustrate a use case.

Thus, at time T=t0 the system is preloaded with devices 1202 and/or 1204 and/or 1206 (either a prior art device or one lacking sponge but having a side-facing fluid- delivery orifice 218 or a device having both the spong and the side-facing orifice 218). At a later time Tl, one of the brush devices (1202 or 1204) is used for a toothbrushing operation and/or with fluid from DD 1252 container. Before the toothbrushing or afterwards (e.g. at most 20 minutes before or at most 10 minutes before and/or at most 20 minutes after or at most 10 minutes after) the first counter 147A is incremented from '0' to T indicating that one toothbrush operation has been performed or one operation using fluid DD has been formed - see Fig. 13B where this was performed using 1204A and the count-state 147A of Fig. 13B is T and the count-state 147B of Fig. 13B is '0' (since no soft-tissue-lubrication operations and/or operations using fluid MM have been performed).

At a later time T2, one of the sponged rod devices (1206 or 1204) is used for a soft-tissue lubrication operation. Before the toothbrushing or afterwards (e.g. at most 20 minutes before or at most 10 minutes before and/or at most 20 minutes after or at most 10 minutes after) the second counter 147B is incremented from '0' to T indicating that one soft-tissue lubrication operations has been performed or one operation using fluid MM has been formed - see Fig. 13C where this was performed using 1204B and the count- state 147A of Fig. 13C is still T and the count-state 147B of Fig. 13C is now T - one of each types of operations (or operations using each type of fluid MM or DD) have been performed.

Figs. 13D indicates that another soft-tissue lubrication operation (or operation with MM) has been performed (e.g. using 1204C).

Figs. 13E indicates that another soft-tissue lubrication operation (or operation with MM) has been performed (e.g. using 1204D).

Figs. 13F indicates that another brushing operation (or operation with DD) has been performed (e.g. using 1204E).

For Fig. 14 see the reference to Fig. 24B. NOTE - the dial counter may be reversible (i.e. it can be incremented or decremented) and/or resettable e.g. back to 'zero'— this is in contrast to the 'punchcard embodiments described below.

Figs. 15A show a different counter - also resettable and/or reversable. The counter of Fig. 15 A, like the dial example, is incremented or decremented by rotation. In contrast, the 'slider' counter of Fig. 15B does not require rotation.

In different embodiments, incrementing the counter can be performed without moving any oral-cleaning device - any brush and/or rodded sponge AND/OR without moving fluid.

In different embodiments, incrementing the counter can be performed without moving any packaging of any oral-cleaning device - any brush and/or rodded sponge

AND/OR without moving fluid.

Figs. 16A-16E are the same as Figs. 13A-13C but illustrate schematically. Figs.

17A-17E is another example.

A description of novel kits, apparatus and methods for performing and tracking an oral-care cycle

Fig. 20 is a flow chart of a method for performing and tracking an oral care cycle. Figs. 21-27 show exemplary kits for performing this method.

Each kit optionally includes a enclosing container (e.g. re-closable or re-sealable container such as first bag 97A) comprising a bottle of moisturizing liquid (MM) and/or disinfectant (DD).

Each kit includes a container (e.g. re-closable or re-sealable container such as second bag 97B) comprising at least 3 or at least 4 oral care devices such that: (i) at least two or at least three of the oral care devices within container (e.g. 97B) are toothbrush- suction hybrid devices having a toothbrush-bristle brush deployed around and/or attached to a suction lumen and (ii) at least two or at least of the oral care devices being sponged- rod devices comprising liquid-absorbing material (e.g. sponge material) attached to a rod assembly.

The container (e.g. re-closable or re-sealable container such as a re-closeable or re-selable bag) 97B may be attached to a substrate board 902 - e.g. from cardboard or thick paper or from plastic or from any other material known in the art) - e.g. suspensded by bag hanger 99B. For example, substrate board 902 may have a hanger 998 via which the boar 902 is held in a vertical position - e.g. like a chart over the patient's bed.

In some embomients, the first 97 A and/or second 97B conainters are attached to the substrate board 902 strongly enough so as to support the weight of the containers and the contents thereof.

The containers 97 A, 97B are labelled as 'bags' but are not required to be bags.

In the example of Figs. 21-26 each oral care devices within the second container 97B are both a(i) 'sponged-rod' and (ii) a lumened' toothbrush-suction hybrid device' or 'suction-lumened-toothbrush. In these examples, the containter 97B is pre-loaded only with devices of Fig. 5A and the contents of the second container 97B are homogeneous with respect to oral care devices. This is not a limitation - in the example of Fig. 16 the contents are heterogeneous with respect to oral devices within the second container 97B - e.g. including some sponged rod devices that are not lumened-toothrbrush devices and some lumened-toothrbrush devices which are not sponged rod devices.

Use of the Multi Displav/Multi Input Counter 149

The structures and usage of multi display/multi input counter 149 are now described.

Multi display/multi input counter 149 is mounted to substrate board 902 and/or disposed within substrate board 902.

In the example of multi-input/multi-display counter 249 comprises (i) two display-screens 480A, 480B mounted side-by-side (i.e. next to each other) onto the substrate board 902 and (ii) buttons 482A and 482B also mounted to substrate board 902. Each display- screen 480 is respectively associated with respective 'increment' button 482 mounted immediately below the display screen - thus, button 482A is mounted below an electrically coupled to the left display screen 480A and button 482B is mounted below an electrically coupled to the right display screen 480B.

. Thus, the multi-input/multi-display counter comprises two user inputs - the 'increment' button 482A directly beneath the left display- screen 480A is the first user input and the 'increment' button 482B directly beneath the right display- screen 482B is the second user input. Upon start-up (i.e. power-on) each electronic panel (480A or 480B) displays '0' - whenever the 'increment' button (button 482A for screen 480A or button 482B for screen 480B) is pushed this increments the number of the display screen directly above the 'increment' button (i.e. from 0 to 1 after a single depression of the increment button, from 1 to 2 the next time the increment button is pressed, and so one).

At any given time, each display screen displays a respective display integer - thus, the multi-input/multi-display counter defines two 'count-states' - the integer displayed by the 'left' electronic panel and the integer displayed by the 'right' electronic panel.

It is noted that in Fig. 21, the entire multi-display multi input counter 149 is mounted to board 902. This is also true in Figs. 22-245.

In the example of Fig. 22, instead of having two separate screens, a single touch screen 481 is provided - touching screen 481 in region 479A thereof increments the first count state, and touching screen 481 in region 479B increments the second count state.

In contrast to the example of Fig. 21 where the counter is electronic, in the example of Figs. 23-25 the counters are mechanical. In the example of Fig. 24, the counter comprises:

145 - first user-input (e.g. a first manually-rotatable pointer)

143 - first counter-state visualization element (e.g. first plurality of ticks disposed around a rotation-center of the manually-rotatable pointer 145) for visualizing a first count-state (i.e. if there are N ticks there are N count-states defined by the combination of 145 and 143 - the tick to which the rotatable-pointer 145 points to defines the first 'count-state')

146 - second user-input (e.g. a second manually-rotatable pointer) 144 - second counter-state visualization element (e.g. second plurality of ticks disposed around a rotation-center of the manually-rotatable pointer 146) for visualizing a second count-state (i.e. if there are N ticks there are N count-states defined by the combination of 146 and 144 - the tick to which the rotatable-pointer 146 points to defines the second 'count- state')

in this non-limiting example, the inputs are first 145 and second 146 manually- rotatable pointers. In this example, the multi-input/multi-display counter 149 comprises first 143 and second 144 visualization elements - for example, first and second pluralies of ticks. The first plurality of ticks 143 is disposed around a center of rotation of the first 145 rotatable pointer. The second plurality of ticks 144 is disposed around a center of rotation of the second 146 rotatable pointer.

The multi-input/multi-display counter 149 independently displays first and second count-states. In the particular example of the drawings, the first count-state is the relative position of first rotatable pointer 145 relative to the first plurality of ticks 143, and the second count-state is the relative position of second rotatable pointer 146 relative to the second plurality of ticks 144. Furthermore, multi-input/multi-display counter 149 includes first and second independently-operable user inputs (in this non-limiting example, the first 145 and second 146 rotatable pointer which rotate around different centers) that are respectively associated with the first and second count-states (in this example, the relative positions of the pointers with respect to the ticks respectively define ).

One example of 'incrementing' a count state is shown in Fig. 14B - in this example, the 'user input' is the single rotatable pointer which is engaged by manual rotation and responds to the manual rotation by moving from one tick to its neighbor, thereby incrementing the displayed count-state.

It will be appreciated that the manual multi-input/multi-display counter (i.e. comprising 143, 144, 145 and 146) shown in Fig. 14A is just one example of manual counter - other manual or electrical/electronic counters may be employed. A non-limiting example of a different multi-input/multi-display counter 149 (e.g. electronic) is discussed below, with reference to Fig.16.

Another example of a manual counter comprising rotatable pointers is shown in Fig. 23.

In Fig. 23-24, the 'user engagement' of the first input 145 was the user manually rotating pointer 145 from one tick (i.e. of 143) to its neighbor. In the example of Fig. 11, the 'user engagement' of the first input 482A is the user pressing button 482A - this increment the first count state (i.e. the number display on electronic display screen 480A). In the example of Fig. 3, the 'user engagement' of the second input 146 was the user manually rotating pointer 146 from one tick (i.e. of 144) to its neighbor. In the example of Fig. 16, the 'user engagement' of the second input 482B is the user pressing button 482B - this increment the second count state (i.e. the number display on electronic display screen 480B).

Figs. 25A-25D show another example. Figs. 25A-25D is a punchcard system where tabs or chads are held within substrate board 902 (e.g. by corrugated or weakened boundaries shown as dotted rounded rectangles). Tabs or chads 912A-912D are associated with the first input/count state - the user input is punching or removing the chad or tab to transform a chad-present portion 912A-912H with a void (shown as a 913. The count-state of the first counter 147 A is the number of voids 913 within 912A-912D. The count-state of the second counter 147B is the number of voids 913 within 912E- 912H. Different count states are shown in Figs. 25A-25D.

One different between the conuter 149 of Fig. 25A-25D and that of fig. 23-24 is that the counter if Fig. 13-14 is reversible - i.e. the dial may be turned clockwise to increment and counter-clockwise to decrement. In contrast, the punchbard-based counter is not reversible.

Examples of dials are illustrated - in other examples, a slide may be used.

Thus, in some embodiments, the incrementing and/or decremetnign of the first count state and/or the second count state is reversible.

In contrast to the examples of Figs. 21-24 where the counter 149 is mounted to substrate board 149, in the example of Figs. 25A-25D, the counter 149 is 'is at least in part embedded to substrate board 149/

Use of the Counter

Fig. 20A-20B are flow charts of methods of tracking an oral care cycle - e.g. using any presently disclosed kit of using another counter (e.g. mounted to a toothbrush device or to a base module thereof- see Fig. 28)

In the examples of Fig. 20A-20B, the order is different - see step S109.

In some embodiments, the presently disclosed methods and/or kits are useful for tracking oral care sessions/operations, and may obviate the need for expensive packaging (see Figs. 1A-1D).

Similar to the situation of United States Patent 7,866,477, the subject (e.g. intubated patient in the ICU) may be subjected to a variety (e.g. at least two different types) of oral care treatments, one of which is the aforementioned toothbrushing treatment described in the previous paragraph. In addition, during his/her stay in the ICU, the same subject may also be subjected to other types of treatment, for example, a gum lubrication treatment wherever a mouth moisturizer is applied to the mouth soft tissue - for example, the soft tissue lubrication treatment may be applied more frequently than the tooth-brushing treatments.

Over a period of several days, subjects/patients are commonly subjected to a repeated 24 hours cycle of oral cleaning. For reducing the risk of contamination, it is typical required that the brush-comprising components will be used only once and then disposed of. Prior art broke down the oral care kits into two type of components - single use heads and 24h hours base handles. The 24h cycle usage was recorded by the depletion of pre-ordered set packages.

In one particular user-case the substrate 902 board (see Figs. 21-27) or the toothbrush device (e.g. electrical toothbrush) or base thereof (see Fig. 28) remains bedside (e.g. as a 'hanging chart') for each patient during his/her entire stay in the ICU, and the multi-input/multi-display counter comprises two miniature (e.g. 2 cm X 2 cm) electronic display- screens (e.g. liquid crystal display (LCD) screens) mounted side-by- side (i.e. next to each other) onto the base module (e.g. see, for example, Fig. 16 and the discussion at the end of the specification). Each display- screen is respectively associated with respective 'increment' button mounted immediately below the display screen. Thus, the multi-input/multi-display counter comprises two user inputs - the 'increment' button directly beneath the left display- screen is the first user input and the 'increment' button directly beneath the right display- screen is the second user input.

Upon start-up (i.e. power-on) (see Figs. 21-22) each electronic display screen displays '0' - whenever the 'increment' button is pushed this increments the number displayed by the electronic display screen directly above the pushed 'increment' button (i.e. from 0 to 1 after a single depression of the increment button, from 1 to 2 the next time the increment button is pressed, and so one). At any given time, each electronic display screen displays a respective display integer displaying the number of times its respective/associated increment button was previously pushed. Thus, the multi- input/multi-display counter defines two 'count-states' - the integer displayed by the 'left' electronic display screen is the first count-state and the integer displayed by the 'right' electronic display screen is the second count-state. Because the substrate board 902 or portion of toothbrush as in Fig. 18 (e.g. a base module of an electrical toothbrush) remains bed-side during an entirety of the patient's stay in the ICU, the base module is a useful location for the multi-input/multi-display counter.

In particular, according to this use case, whenever the ICU patient is subjected to a first type of treatment (i.e. tooth brushing treatment), the care-giver manually engages the first user-input (i.e. by depressing the increment button beneath the left display screen) - this increments the first count-state (i.e. the integer on the left display screen - i.e. from 0 to 1, from 1 to 2, and so on). Whenever the ICU patient is subjected to a second type of treatment (e.g. mouth-moisturizing treatment), the care-giver manually engages the second user-input (i.e by depressing the increment button beneath the right display screen) - this increments the second count-state (i.e. the integer on the right display screen - i.e. from 0 to 1, from 1 to 2, and so on).

Each screen displays its respective display screen, which is visible to anyone who wishes to read the 'count-state' afterwards (e.g. the same nurse, or another nurse from the next shift).

In this manner, at any given time any nurse in the ICU may read from the base- module-disposed counter the number of previous treatments of the first and second types to which the intubated patient has previously been subjected. The nurse will read the base -mode and know the number of previous toothbrush-treatments and the number of previous mouth-moisturizing treatments - this will help the nurse decide if the next treatment to the intubated patient will be a toothbrush treatment or a mouth moisturizing treatment.

Since the base is re-used for different toothbrushing sessions and remains by the patient's bedside during an entirety of his/her stay in the ICU, this information (i.e. about the previous number of treatments of the first and second types) is readily available to any nurse in the ICU.

Since this information about the absolute and relative numbers of previous treatment of each type is readily available, there is no need to individually provide different types of oral care packs wwithin compartments of a multi-compartment packaging, such as that disclosed in United States Patent 7,866,477. Thus, in some embodiments, the presently-disclosed teachings allow for the hospital to do away completely with per-patient oral-care kits of the type disclosed in United States Patent 7,866,477. Instead, it is possible to employ a much more 'primitive' (but cheaper and less space-consuming) packaging where the oral care packs are stored in bins or bags - for example, bag or bin "A" includes only oral care packs of the first type, bag or bin "B" includes only oral care packs of the second type, and so on.

When a nurse approaches a given patient, s/he can check the 'hanging substrate 902' or the toothbrush (or base module) disposed near the patient's bed to read, from the base-module-disposed counter, the number of previous treatments of each type applied to the patient. As such, the nurse can instantly ascertain the next type of oral-care treatment required in the oral care cleaning cycle, take the appropriate oral care element(s) (e.g. in a treatment pack) from the appropriate bag (e.g. bag or bin 'A' or bag or bin 'Β'), and subjects the patient to this oral-care cleaning procedure using the oral care element(s) obtained from the appropriate bag. If appropriate (e.g. if the oral-care cleaning procedure involves brushing the patient's teeth), this oral care procedure may be performed using the base module as a toothbrush handle.

After performing a particular type of treatment, the nurse simply increments the counter appropriately. Thus, for treatments of type 'A' (e.g. using cleaning elements(s) from bag or bin 'Α') the multi-input/multi-display counter 149 is operated to increment a first count-state (e.g. to depress the button directly beneath the left display screen to increment its display integer). For treatments of type 'B' (e.g. using cleaning elements(s) from bag or bin 'B') the counter 149 is operated to increment a second count-state (e.g. to depress the button directly beneath the left display screen to increment its display integer).

Additional Optional Features

In some embodiments, the kit is provided so that all of the plurality of oral care devices co-reside within the resealable container so that there is no sterile barrier between any of the oral care devices within the resealable container.

In some embodiments, the kit is provided so that all of the plurality of oral care devices co-reside within the resealable container 97B so that they are not attached to each other and are not within intermediate containers that are attached to each other. In some embodimens, the counter is relatively 'flat' - e.g. having a thickness of at most 2 cm or at most 1.5 cm or at most 1 cm or at most 0.75 cm or at most 0.5 cm.

In some embodimetns operation of the counter to increment or decrement one or both of the count states does not move any oral care device (e.g. in general or within container 97B) - i.e. does not move any spounged rod device and/or does not move any lumened toothbrush device.

In some embodiments, the counter is relatively 'small' - e.g. a maximum dimension of length/width/thickness is at most 20 cm or at most 15 cm or at most 10 cm or most 7.5 cm or at most 5 cm..

In some embodiments, a total number of 'first count states' (ie.. including a 'zero' count state) (e.g. of 147A) is at least 3 or at least 4 or at least 5 and/or a total number of 'second count states' (e.g. of 147B) is at least 3 or at least4 or at least 5. In the example of Fig. 13 the total number of 'first count states' is four (i.e. 0, 1, 2, 3) and the total number of 'second count states' is 7 (i.e. 0, 1, 2, 3 , 4 , 5, and 6). In some embodmietns, the total number of count states for the first counter exceeds the total number of count states for the second counter.

In some embodiments, the counter is operated outside of the container 97B in which the oral care devices are disposed.

In some embodiments, motion of an oral care device (or motion of a container of the brush - e.g. detaching the container from an object to which is attached) does not increment or decrement either count states - i.e. it I spossible to incrfement or decrement the first and/or second count states (ie.. by 'user input') without moving any oral care device and/or any container thereof.

In some embodiments, a thickness of substrate board 902 is at most 2 cm or at most 1 cm.

Bactericidal Effectiveness

For the present disclosure, a bactericidal effectiveness for our purpose is quantified by the measure of "minimum bactericidal concentrations" (MBC) and is Determined by in vitro test as described in https://www.ncbi.nlTn.nih.gOv/pmc/ardcles/PMC4362091./ (Comparison of the Antibacterial Properties of Three Mouthwashes Containing Chlorhexidine Against Oral Microbial Plaques: An in vitro Study ) provided as an appendix

Briefly summarized the test comprises the steps of: isolating colonies of Streptococcus mutans; tube dilution method is used for determining the minimum bactericidal concentrations (MBC).

Another Discussion - FIG. 19A-19G and 28

Embodiments of the present invention relate to a rodded oral care device which may be (i) a toothbrush device (e.g. suction lumen toothbrush) or to (ii) fluid applicator device (e.g. having a fluid-delivery lumen through which fluid is actively forced into the mouth or a more 'passive' fluid applicator device such as a sponged rod or a swab device).

Exdample of rodded oral care devices or portions thereof are shown in Figs. 19A-19G and 28.

In one particular example, at least some the toothbrush bristles are 'high-aspect- ratio-cross-section bristles' (see 'leaf bristles of 946 of Fig. 28)- i.e. an aspect ratio of a cross section of the bristles exceeds at least 1.5 or at least 2 or at least 3 or at least 5 - e.g. some leaf-bristles exhibit this characteristic.

In one particular example, a cross-section area of the bristle increases as one moves from the bottom of each bristle towards the top thereof .

In one particular example, the bristles are 'leaf-bristles'.

The bristles (i.e. for a bristled-rod device) or the liquid-retaining element (i.e. for a liquid-retaining rode device) may be integrally formed with the rod (e.g. by injection molding or 3D-printing) or may be separate elements attached to and/or mounted onto the rod.

Optionally, a rodded oral-care device comprises a lumen - e.g. the rod itself may be hollow or a lumen may be disposed along the length of the rod.

A brief description of some novel toothbrush devices (e.g. mountable to a base) At least some of Figs. 19A-19G show a novel oral care device that is both a(i) 'sponged-rod' and (ii) a lumened' toothbrush- suction hybrid device' or 'suction- lumened-toothbrush. These 'hybrid' devices are labelled 1204A. One salient feature of the hybrid devices of Figs. 5-8 is that they serve two functions - brushing during a 'brushing session' and introduction of moisturizing liquid (MM) during a 'moisturizing session' which can provided as separate sessions. To introduce moisturizing liquid (MM) during the 'moisturizing session' it is possible to pre-soak .g. by pre-soaking the sponge 954 in moisturizing liquid (MM). Having the 'hybrid' device obviates the need to use one type of specific device for tooth-brushing and another specific type of device during toothbrushing- the same brush can be used for each type of session.

In contrast, the novel oral care device of another figure is only a lumened' toothbrush-suction hybrid device' 1202 or 'suction-lumened-toothbrush and is not as sponged-rode device and does not have side-facing orifice 218 for fluid delivery.

Also shown is illustrates a different type of hybrid brush head/rodded device which once again obviates the need to use one type of specific device for tooth-brushing and another specific type of device during toothbrushing- the same brush can be used for each type of session.

In some embodiments, moisturizing liquid (MM) is provided by pre-soaking the sponge 954, soo it is possible to store moisturizing liquid (MM), within reservoir 120 and to deliver moisturizing liquid (MM) (e.g. having a 'flowable' viscosity substantially equivalent to water at room temperature) into the mouth fluid-delivery orifices 218A, 218B. The fluid would be leave 120 as pressurized fluid. This could be performed simultaneous with suctioning via orifice 172.

Thus, by virtual of sponge 954, the devices 1204A of are "rodded devices having a sponge or a side-facing orifice(s)" 1204.

By virtual of side-facing orifice(s) 218, the devices 1204B are "rodded devices having a sponge or a side-facing orifice(s)" 1204.

Thus, some embodiments relate to a rodded oral-care device (e.g. a head module 150 for an oral care device comprising): a. a suction lumen 170 defining a central axis 938 (e..g at least in the section populated by toothbrush bristles) and having a distal orifice 968 (e.g. facing along the central axis), the suction lumen section defining first (e.g. the front facing direction 942) and second (e.g. rear-facing direction 946) mutually exclusive 180 degree arcs around the central axis 938; b. a plurality of sideway-facing toothbrush bristles (ie.. of toothbrush-bristle brush 948) deployed on the suction lumen (e.g. on a bristle-retaining surface of a solid object within which the suction lumen is embedded - e.g. 160) so that bases of the toothbrush bristles are present on each of the z (z=2) mutually-exclusive 180 degree arcs; c. liquid-absorbing material (e.g. sponge material) 954 deployed around the suction lumen section(e.g. on a bristle-retaining surface of a solid object within which the suction lumen is embedded - e.g. 160) so that liquid-absorbing material (e.g. sponge material) is present 945 on each of the z (z=2) mutually-exclusive 180=360/z (z=2) degree arcs (e.g. in locations that axially overlap) for each of the 180=360/z (z=2) degree arcs, the toothbrush bristle. In some embodiments, wherein the suction lumen 968 e.g. defines a distal suction orifice facing along the central axis.

This is true for z=2 and angle = 360/z=180.

In some embodiments, this also is true for z=3 and angle arc = 360/z = 120.

Thus, some embodiments relate to a rodded oral care device (e.g. head module 150() f°^{r an ora}l ^care device comprising: a. a suction lumen 170 defining a central axis 938 (e..g at least in the section populated by toothbrush bristles) and having a distal orifice 968 (e.g. facing along the central axis), the suction lumen section defining first (e.g. the front facing direction 942) and second (e.g. rear-facing direction 946) mutually exclusive 180 degree arcs around the central axis 938; b. a plurality of sideway-facing toothbrush bristles (ie.. of toothbrush-bristle brush 948) deployed on the suction lumen (e.g. on a bristle-retaining surface of a solid object within which the suction lumen is embedded - e.g. 160) so that bases of the toothbrush bristles are present on each of the z (z=3) mutually-exclusive 120 degree arcs; c. liquid-absorbing material (e.g. sponge material) 954 deployed around the suction lumen section(e.g. on a bristle-retaining surface of a solid object within which the suction lumen is embedded - e.g. 160) so that liquid-absorbing material (e.g. sponge material) is present 945 on each of the z (z=3) mutually-exclusive 120=360/z (z=3) degree arcs (e.g. in locations that axially overlap) for each of the 120=360/z (z=3) degree arcs, the toothbrush bristle. In some embodiments, wherein the suction lumen 968 e.g. defines a distal suction orifice facing along the central axis.

In some embodiments, this also is true for z=4 and angle arc = 360/4 = 90.

In some embodiments, this also is true for z=5 and angle arc = 360/4 = 72. In some embodiments the bristles and the liquid-absorbing material (e.g. sponge material) are deployed at a distal end of the head module, the device further comprising a conical chamber that is sealed away from the suction lumen, the conical chamber being disposed at a proximal end of the head module and facing proximally, the conical chamber being sealed away from an interior of the suction lumen.

In some embodiments, the bristles and the liquid- absorbing material (e.g. sponge material) are deployed at a distal end of the head module and/or the device further comprising a conical chamber (e.g. defined by 179) that is sealed away from the suction lumen 170, the conical chamber being disposed at a proximal end of the head module and facing proximally (e.g. to base and/or tail), - e.g. the conical chamber being sealed away and/or separate (e.g. not connected in the cross section) from an interior of the suction lumen.

In some embodiments, neck portion separates between the toothbrush bristles and the conical chamber.

Embodiments relate to use of the presently-disclosed head model - e.g. inserting a vibrator (e.g. run by electric motor) into the chamber defined by 179 - e.g. simultaneous with suction).

Some embodiments relate to a rodded oral care device (e.g. head module 150() for an oral care device comprising: a. a suction lumen 170 defining a central axis 938 (e..g at least in the section populated by toothbrush bristles) and having a distal orifice 968 (e.g. facing along the central axis), the suction lumen section defining first (e.g. the front facing direction 942) and second (e.g. rear-facing direction 946) mutually exclusive 180 degree arcs around the central axis 938; b. a plurality of sideway-facing toothbrush bristles (ie.. of toothbrush-bristle brush 948) deployed on the suction lumen (e.g. on a bristle-retaining surface of a solid object within which the suction lumen is embedded - e.g. 160) so that bases of the toothbrush bristles are present on each of the z (z=3) mutually-exclusive 120 degree arcs; c. a field 946 (e.g. see Figs. lOA- lOC) of leaves/fluid distribution element (i.e. each leaf having a cross-section aspect ratio (i.e. aspect ratio of a cross section of the leaf that is at least 1.5 or at least 2 or at least 3 or at least 5 or at least 7.5 or at least 10)deployed around the suction lumen section(e.g. on a bristle-retaining surface of a solid object within which the suction lumen is embedded - e.g. 160) so that leaves of the field 946 (and optionally fluid-delivery orifices 218) are present 945 on each of the z (z=3) mutually-exclusive 120=360/z (z=3) degree arcs (e.g. in locations that axially overlap) for each of the 120=360/z (z=3) degree arcs, the toothbrush bristle. In some embodiments, wherein the suction lumen 968 e.g. defines a distal suction orifice facing along the central axis.

In some embodiments, this also is true for z=4 and angle arc = 360/4 = 90.

In some embodiments, this also is true for z=5 and angle arc = 360/4 = 72.

In some embodiments, the toothbrush bristles and the leaf-field 946 are deployed at a distal end of the head module, the device further comprising a conical chamber that is sealed away from the suction lumen, the conical chamber being disposed at a proximal end of the head module and facing proximally, the conical chamber being sealed away from an interior of the suction lumen.

In some embodiments, the bristles and the field 946 of leaves and/or fluid- delivery orifices are deployed at a distal end of the head module and/or the device further comprising a conical chamber (e.g. defined by 179) that is sealed away from the suction lumen 170, the conical chamber being disposed at a proximal end of the head module and facing proximally (e.g. to base and/or tail), - e.g. the conical chamber being sealed away and/or separate (e.g. not connected in the cross section) from an interior of the suction lumen.

In the example of Fig. 5A, fluid-delivery orifice 218 is located within a field of toothbrush bristles. In contrast, in other examples (e.g. FIG> 28) orifice 218 is fluid delivery orifice 218 is not located within a field 948 of fluid-delivery bristles - instead fluid delivery orifice 218 is located within a field 946 of fluid-distribution elements or 'leaves' which each have an aspect ratio (i.e. an aspect ratio of the cross section of each leaf where the 'cross section' is in the plane perpendicular to a central or elongate axis along a length of each fluid-distribution elements or leaves - the aspect ratio of each 'wide' leaf (e.g of a cross section thereof) may be at least 1.5 or at least 2 or at least 3 or at least 5 or at least 7.5 or at least 10).

In some examples (e.g. FIG. 28 which shows 'stripes'), when pressurized fluid is forced to exit orifice 218 (e.g. pressurized fluid expelled from container 120 - e.g. by applying pressure to container 120) the fluid leaves orifices in a location within the field of fluid-distribution elements or leaves which, for example, can serve to distribute the movement of the fluid so that fluid movement is not restricted to locations where a 'jet' of fluid leaves orifice 218. Thus, in some embodiments, there may be alternating 'stripes' (i.e. arranged lengthwise along the suction lumen 160) of a field 948 of toothbrush-bristles and field 946 of leaves where each leaf of at least a majority of leaves therein has an aspect ratio of at least 1.5 or at least 2 or at least 3 or at least 5 or at least 7.5 or at least 10).
