Description

BACKGROUND OF THE INVENTION

Embodiments of the present invention generally relate to an apparatus and system for washing, cleaning, drying, and/or delivering medicine to a region of a human body. More specifically, aspects of the present invention provide a method and apparatus for delivering and applying water, medication, and/or a cleaning solution to a region of the body (e.g., genital or anal area, intimate parts, perianal region) which may be difficult for the user to access and dry the region.

DESCRIPTION OF THE RELATED ART

Bidets and other modern toilet seat systems have been used to spray water and clean private parts of a user using a toilet. The bidet systems are used for washing the genital and anal areas using cleaning water of appropriate temperature sprayed from the center of the bidet system, instead of a toilet paper after relief stool or urination. Originally being developed for washing the pubic area for females, bidet systems have now been popular among people of all ages and both sexes because it is known to be more hygienic to wash the intimate parts and anus with water instead of paper after relief. In addition, cleansing the pubic/anal regions with water may help to avoid infection and prevent hemorrhoids and other anal disease. Furthermore, it is very effective for women with gynecological diseases. It is also very useful for the elderly or obese people to relieve themselves with great convenience.

However, most bidets and bidet seat cleaning systems have a water spray nozzle located to be positioned near the posterior or anal area and thus is not suitable for washing and cleaning female anterior private parts. In addition, bidet systems are expensive and need to be pre-installed. Further, the drying mechanisms of most bidets and bidet seat systems are not freely movable or localized to the area that need to be dried. Also, most bidets and bidet seat systems are not equipped with appropriate cleaning solutions or medications that are stored and delivered in mechanisms that can be freely movable or being localized to the area that need to be cleaned. Therefore, there is a need for a convenient, easy to carry wash and clean apparatus for cleaning genital or anal area of a human body.

DETAILED DESCRIPTION

The present invention generally includes a method and a seat and cover system having a toilet seat assembly, a drying nozzle assembly, a spraying nozzle assembly, and a medicine delivery assembly for delivering and applying water, cleaning solutions, and/or medicines to a region of a human body that may not otherwise be easily accessible (e.g., to the perianal region), as well as washing and drying the region of the human body. In addition, a method of operating the seat and cover system is also provided.

FIG. 1 shows one example of a bidet seat and cover system, such as a bidet seat system 100. As shown in FIG. 1, the bidet seat system 100 may generally include a toilet seat assembly 200, a spraying nozzle assembly 300 having a spray nozzle unit 330, and one or more control units 340, 342. The bidet seat system 100 can be placed on top of a traditional toilet bowl with fitted sizes and shapes (oval or round). In one example, the toilet seat assembly 200 can be installed to a toilet system by removing any existing seat from a traditional toilet system and replacing a traditional seat with the bidet seat system 100. In another example, the bidet system 200 may have fastening elements (e.g., screws, bolts, velcro, etc.) in its base to be connected to a traditional toilet bowl.

As shown in FIG. 1, the toilet seat assembly 200 includes a seat cover 210, a base housing 220, a seat 230 and a base 240. The seat cover 210 is generally closed to cover the base 240. During operation or in idle position, the seat cover can be opened and positioned upward, such as being positioned against a water tank. The seat 230 includes a seat body 232 facing upward so that a human subject can sit thereon.

The base housing 220 and the base 240 are formed to connect the seat cover 210 and the seat 230 together, for example, using one or more hinges such that the seat cover 210 can be opened or closed against the seat 230. The housing 220 and the base 240 are used generally to house one or more assemblies (e.g., the spraying nozzle assembly 300, a drying nozzle assembly 600, and a medicine delivery assembly, etc.) therein. As shown in FIG. 1, the spray nozzle unit 330 is adapted to be retractable and can be positioned inside the base housing 220 and extended out in a direction “R” to move in three dimensional rotational direction and in a horizontal plane “H”. The spray nozzle unit 330 positioned near the bottom of the seat body 232 can be adjusted to be retracted back into the base housing 220.

In one embodiment, the function and operation of the bidet system 100 is controlled by one or more control units, such as a control unit 342 positioned adjacent to one side of the bidet system 100, and a controlled unit 340, which can be positioned at a distance away from the bidet system in a wired or wireless fashion. In FIG. 1, two control units 340, 342 are configured, where the control unit 342 is positioned to be adjacent the seat body 232 to be closer for a user to control the movements of the spray nozzle unit 330 of the spraying nozzle assembly 300 as well as the temperature and pressure of the spraying liquid spraying from the spray nozzle unit 330. Alternatively, the control unit 340 may be a remote controlled unit being capable of communicating with the bidet seat system 100.

The remote control units 340, 342 are adapted to be communicating and directing one or more movements of the spraying nozzle unit 330. The spray nozzle unit 330 is adapted to jet a solution, such as water or any liquid, a cleaning solution, a barrier spray solution, a medicine-containing solution, and combinations thereof to a localized region (e.g., perianal region) of a human body private part. In one example, the spray nozzle unit 330 is adapted to move in a direction marked as “R” to be extended and retracted in and out. In another example, the spray nozzle unit 330 is adapted to move in a vertical direction marked as “V” to move up and down (e.g., in a Z-direction or a gravitational direction), particularly after the spray nozzle unit 330 has been extended and retracted out. In another example, the spray nozzle unit 330 is adapted to move in a horizontal direction marked as “H” to move left-right, particularly after the spray nozzle unit 330 are extended and retracted out.

The remote control units 340, 342 can cause the user to operate the operation button reliably. The remote control units can provide “hands-free” options, therefore avoiding some discomfort or embarrassment from the user. For example, control units 340 can be mounted on the wall adjacent to or far away from the toilet. The control unit 340 has a screen and a keyboard with pushbuttons for turning the water or air on and off, for controlling the air temperature, etc. The water flow level may be selected by appropriate command through the remote control unit. The remote control unit is used to transmit appliance control data to the bidet seat system 100. Inside the bidet seat system 100, a decoder decodes the transmitted data. When the data is decoded, the bidet seat system 100 responds to an appliance control signal suitable for controlling the spraying nozzle assembly 300 and other parts within the bidet seat system 100. As another example, control units 342 can be mounted on the base 240. It enables a user to directly control the bidet seat system 100.

In one embodiment, the spraying nozzle assembly 300 includes a driving motor unit 320 to direct and drive the movements of the spray nozzle unit 330. The driving motor unit 320 is connected to a motor 324.

In another embodiment, the spray nozzle unit 330 includes one or more first spray nozzle body 332 and one or more second spray nozzle body 334, which are configured to function together and adapted to be retractable (as shown in a “R1” direction for extending and retracting movements) and movable in three-dimensional rotational motion, as driver by one or more driving motors (such as a driving motor 324, etc.) and steering gears (such as steering gears 321, 323, etc.) for delivering a solution therein.

Inside the first spray nozzle body 332 and the second spray nozzle body 334, there may be one, two or more spray nozzle channels, such as a first spray nozzle channel 362 and a second spray nozzle channels 364. Both of the first spray nozzle channel 362 and the second spray nozzle channels 364 are connected to the same or different liquid lines (such as liquid lines 370, 380 as shown in FIG. 4) for delivering one or more liquid solutions therein. Suitable solutions include water, a cleaning solution, a barrier spray solution, a medicine-containing solution, and combinations thereof. For example, medications, cleaning solutions, moisturizing creams, lotions, skin sealants, moisture barriers, skin protection paste, ointments, pastes or solutions of mineral oil, silicone fluids (e.g. dimethicone and cyclomethicone), petrolatum, cod liver oil, lanolin, zinc oxide, talc, calamine, kaolin, topical starch and allantoin, lotions, fluids medicaments, skin protection fluid, chemical suspensions, and/or a pharmaceutical formulation to a surface area of a human subject. For example, Desitin® ointment (Pfizer, Inc.) is probably the most common topical used in treating diaper rash and other rashes. It contains common barrier materials (zinc oxide and petrolatum) and additionally contains two common skin conditioning agents (cod liver oil and lanolin).

Also shown in FIG. 2 is the drying nozzle assembly 600, which includes a drying nozzle unit 630 having a retractable element 634 and a nozzle tip portion 632.
