System, method and kit for oral care

An oral care kit comprising:

• a. a base module comprising:
• i. an onboard compressible fluid reservoir having an equilibrium size so that, when released from a compressed configuration, a restoration force urges size-increase of the reservoir back to the equilibrium size;
• ii. an onboard inlet lumen comprising a proximal tube portion that:
• A. protrudes from a main body of the base module;
• and
• B. has a proximal opening,
• the inlet lumen providing fluid communication between the proximal opening of the proximal tube portion and the compressible fluid reservoir for loading thereof;
• iii. a first one-way valve disposed between the proximal opening of the proximal tube portion of the inlet lumen and the compressible fluid reservoir so as 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;
• v. a second one-way valve disposed in the onboard fluid-delivery lumen section to permit fluid outflow 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 that does not lead into the fluid compressible reservoir;
• b. a plurality of rodded oral care devices, at least one of which is a suction-lumened-toothbrush including an head-module onboard suction lumen section, an onboard fluid-delivery-lumen section having a fluid-delivery-orifice at a distal end of the head-module-onboard fluid-delivery-lumen section, and a plurality of toothbrush bristles;
• c. a hanger;
• d. a support element that hangs from the hanger, the support element for supporting each rodded oral care device of the plurality of devices;
• and
• e. a non-electronic multi-input multi-display counter attached to and supported by the hanger 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,
• 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 form a continuous suction lumen along a length of oral care device;
• and
• B. the respective fluid-delivery sections 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 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 through the base-module-onboard fluid-delivery lumen section and into the fluid reservoir;
• 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 one-way valve while a presence of the first one-way valve prevents flow of fluid from passing back towards proximal opening of the inlet lumen.
