BACKGROUND

Field

Sanitary washing apparatuses, systems, methods, and kits for the anal and genitalia anatomy.

Maintaining cleanliness of the anal and genital areas is a problem as old as time. The bidet dates back to use in France in the 1600s and provided a wash basin which was used as a second step to the use of a chamber pot. Standalone bidets are still popular in Italy, Portugal, Japan, Argentina and Venezuela.

During the U.S. Civil War, President Lincoln and his Cabinet used then groundbreaking Gayetty's Medicated Paper in the water closet (i.e., when using the toilet). The next noteworthy improvement occurred when Wheeler invented perforated paper on a roll (U.S. Pat. No. 465,588) in 1891. Starting in the 1880s flush toilets (known as water closets) were also introduced in the homes of the wealthy and hotels. Still, as late as 1940 nearly half of the houses in the US lacked hot piped water, a bathtub or shower, or a flush toilet.

As indoor plumbing became increasingly common, more and more homes installed toilets. While bidets are more hygienic than standard toilet paper, the widespread adoption of the bidet has lagged. The lag in the adoption of bidets in the US is likely influenced by the fact that bidets are typically stand-alone devices not easily retrofitted into many homes and facilities. In order to overcome the retrofitting issue, bidet attachments (e.g., bidet toilet seat adapters) have been developed for use with a standard toilet. However, the bidet adapters do not deliver the same level of cleanliness that a standalone bidet delivers. Neither the adaptive or stand-alone bidet provide a targeted spray that focuses fluid application to a specific area of interest, or a fluid that contains a cleaning agent.

As the world comes to terms with the ubiquitous nature of germ transmission following, for example, the COVID-19 pandemic, awareness of the importance of hygiene has increased. Additionally, as younger generations desire to reduce negative impacts on the environment caused by various activities of modern life, awareness of the impact toilet paper has on deforestation and the amount of energy and water required to make a single roll of toilet paper has become a pressing environmental issue for many.

What is needed are systems, devices, methods, and kits for adapting a standard toilet that works with the existing water supply to provide the functionality of a bidet that also has the hygienic features of a bidet. Additionally, what is needed are solutions that provide a soap-free, zero residue cleaning agent. Lastly what is needed is a way to provide an improved fluid spray that accurately targets the anatomical area of interest.

A concentrate can be used as part of the disclosed personal hygiene washing system. The concentrate may have one or more of, for example cleaning, antibacterial, fragrant, medicinal, pharmaceutical and therapeutic properties. The concentrate can, for example, be in a liquid form, crystalline form, granules form, powder form, tablet form. The concentrate can further be provided in a capsule or a dissolvable casing, e.g., a capsule containing liquid, crystals, granules, powder or tablets. In some configurations, the capsule or dissolvable casing can provide one or more compartments to maintain ingredients separate until the final mixing step.

The user of a concentrate with a fragrance has the benefit of leaving the user with a pleasing scent after using the device and also providing a fragrance into the room . Providing a fragrance into the room during use also acts as a room deodorizer.

The concentrate may contain a surfactant or cleaning agent, for instance a nonionic surfactant such as a sorbitan oleate decylglucoside crosspolymer. Prebiotics can include galactooligosaccharides, fructooligosaccharides, Konjac glucomannan hydrolysate and others to promote growth of lactobacillus acidophilus in the perineum, anus and vagina. Postbiotics can include lactic acid which is a natural antibacterial for the perineum, anus and vagina.

An example of a concentrate is a liquid containing one or more of a no-rinse surfactant, a scrubbing agent and emollient, a prebiotic (e.g., for vaginal health), a postbiotic, and/or antibacterial. The scrubbing agent and emollient can be a hydrolyzed protein such as oats. The prebiotic can be an oligosaccharide (e.g. derived from beans or chicory). The postbiotic, and/or antibacterial can be a lactic acid (e.g., derived from cultured beet sugar). The concentrate can be formulated to be soap free, i.e. free from compounds having a general formula (RCO−)nMn+(Where R is an alkyl, M is a metal and n is the charge of the cation). The concentrate can also be formulated to provide zero residue and rise off without requiring an additional manual drying step.

The fluid can be pre-diluted or a concentrate ready for dilution. Additionally, the concentrate can be formulated for single use or for application over a plurality of uses.

X. Methods Of Installation

An installation kit can be provided. During installation, the user can perform one or more of the following steps:

Turn off the shut-off valve118;

Empty the toilet tank by activating the toilet flush;

Disconnect the existing water supply line116between the shut-off valve118and the toilet tank114fingers, hand, finger wrench600or other tools;

Connect the adapter400between the water supply line116and the toilet tank114using fingers, hand, finger wrench600or other tools to engage the hex head plumbing connector(s)120;

Secure the docking station500to a surface;

If not already connected, connect the unidirectional hose800to a proximal end of the fluid applicator200at one end and an adapter400at a second end;

If not already connected, connect the bidirectional hose700to the mixing pod300at a first end and to the adapter400at a second end;

Position the mixing pod300near the adapter400; the mixing pod can be secured to a surface or placed on a surface; and

Turn on the shut-off valve118.

XI. Method of Use

A. Filling the Mixing Pod

The user adds the concentrate to the mixing pod300via, the insertion hatch304;

The valve state of the adapter400valve can be changed using the adapter valve controller405to permit water to be directed from the toilet tank114to the adapter400; and

The filling controller305of the mixing pod300is activated to allow water to fill the mixing pod300.

The filling process can be automatic or semi-automatic once activated by the user. When the filling process is automatic, the mixing pod300is filled which allows the fluid to come to and be maintained at room temperature in between uses. If the user refills the mixing pod300after use, the same result with respect to fluid temperature can be achieved. Allowing the fluid to be maintained in the mixing pod300at room temperature can be beneficial where the system is installed in a cold climate where water temperature from an inlet may be colder than comfortable for the user.

In one method, the user can activate the filling controller305by pressing a button and holding the button until the user achieves visual confirmation that the mixing pod300is full. In another method, activation of the filling controller305can cause a predetermined amount of fluid to enter the mixing pod300. In another configuration, water is added via a refillable tank.

The system is configurable to pre-mix water with a concentrate within a mixing chamber before integration with a water flow source for applying the liquid onto the body.

As described above, the mixing mechanism may have a button, lever, valve or other mechanism that allows the user to fill the mixing chamber with water from any suitable water supply. An auto-stop mechanism may be implemented to prevent overflow of mixing chamber with water or liquid. Alternatively, the mixing mechanism may have a hatch or other opening that allows user to fill the mixing chamber with water or other liquid.

The mixing chamber may also include an agitator, a UV applicator, or other mechanism to facilitate the mixing and/or sterilizing the concentrate and the water. Mechanisms may be powered by the movement of water through the system (such as water turning a turbine), an external power source, or other mechanical forces.

Concentrate or a pre-mixed solution can be mixed with water flow for spraying on the body, using a venturi, diversion, or other mixing mechanism.

C. Device Usage

A user positions the fluid applicator200so the triangular fluid delivery aperture203is directed toward a target area of interest;

The user activates the fluid applicator200by engaging the fluid controller204. Activation of the fluid controller204can be achieved by, for example, pressing a button or using a digit to move a button in a proximal direction within an aperture in the fluid applicator200;

Fluid passes from the mixing pod300and/or the water supply line116via the fluid applicator200to the target area of interest to apply a fluid in a substantially straight stream with reduced splash; and

The user moves the fluid applicator200to other areas of interest as needed.

If the user incorporates the use of the no-rinse nonionic surfactant, no further steps may be required to achieve a dry surface finish. If water is used, then an additional drying step may be taken either via the device or with the use of a secondary material.

In some configurations, water can be applied to the user in a second step.

In some configurations, the fluid may be warmed prior to application for additional comfort of the user in a cold climate.
