The present invention relates generally to hygiene devices and hygiene stations. More particularly, the present invention relates to disposable hygiene devices, mobile hygiene stations and integrated hygiene stations. The present inventions are advantageously used by individuals having mental or physical impairments that make completion of hygiene tasks difficult or impossible. The present inventions are also advantageously used by individuals in locations where completion of hygiene tasks is difficult.
Typically, individuals have been restricted to conventional bathrooms in performing hygiene functions, such as using the toilet, washing and or grooming, regardless of their age, physical abilities or mental faculties. However, conventional bathrooms can be problematic for various individuals, such as persons having physical or cognitive disabilities. This is specifically the case for individuals that use mobility assisting devices such as wheelchairs, canes, walkers or the like. As an example, conventional bathroom designs, in both home and institutional environments, may require that an individual in a wheelchair perform a complex ‘dance’ to perform hygiene tasks including traversing around objects and through doors to get to the bathroom, manipulate the door, transfer themselves from the wheel to the toilet, then again from the toilet to the wheelchair to wash his or her hands, and then reverse their traverse. On top of this, conventional bathroom designs also tend to offer insufficient space to allow a caregiver to assist the individual.
In addition, there are various times and situations where performing hygiene functions is inconvenient or unsanitary. For example, truckers, RV-ers, campers and other travelers may not have ready access to bathrooms. In addition, bathrooms that are available may not be suitable as they are not suitably clean.
As such, there is a need for disposable hygiene devices, portable hygiene stations and integrated hygiene stations that provides greater accessibility to individuals in all places including bathrooms. More particularly, there is a need for hygiene devices and hygiene stations designed to assist individuals and caregivers in the performance of toilet and hygiene tasks.
The present invention comprises a disposable hygiene device with a toilet seat with a top and bottom surfaces, where the toilet seat folds for storage before or after use. A receptacle is attached to the bottom surface of the toilet seat. After use, an adhesive on the top surface of the toilet seat is exposed by the removal of a protective layer. The toilet seat may then be folded onto itself to seal the hygiene device for easy disposal. The toilet seat may also include handles or an extension to ease proper orientation and use of the disposable hygiene device. The present invention also includes hygiene stations, preferably portable, that may be used with the disposable hygiene device, hygiene stations that include rotatable, extendable and height adjustable bathroom fixtures, and hygiene stations have a common connection point for inputs and outputs.
The present invention, referring to
For those who are able, the disposable hygiene device may be held in place during use. Alternately, as described below, the disposable hygiene device may be supported by a hygiene station during use. In either situation, the disposable hygiene device provides a convenient method of accomplishing the toileting function when a toilet is not available or accessible. Also, even when a toilet is available and accessible, the disposable hygiene device provides a sanitary method of accomplishing the toileting function or a convenient method of collecting samples to be used in a variety of medical tests.
In one preferred embodiment, the topside of the toilet seat 12 includes an adhesive 16 covered by a protective layer 18 that is peel removable. After use, the protective layer may be removed to expose the adhesive. After exposure, the adhesive may be adhered to a separate cover panel or layer (not shown) to seal the receptacle. In a preferred embodiment, one portion of the toilet seat is adhered to another portion of the toilet seat to form a sealed receptacle. To facilitate the adhering the toilet seat to itself, the toilet seat may include one or more fold lines 20. The fold lines ease the requirements for folding the toilet seat on to itself. Preferably, the toilet seat is folded in half.
The toilet seat may include a pair of handles 22 located opposite each other. The handles facilitate holding the device in place during use. For example, the individual may use the handles to hold the device during use. The handles also provide a visual orientation cue for the proper use of the device, which may be important for individuals with cognitive difficulties.
The toilet seat may also contain other visual orientation cues in the form of an extension 24 as best seen in
As discussed below, the handles and/or extension may also help orient the device on a hygiene station.
The toilet seat may be made of any material, whether considered disposable or not. For example, metal, plastic, ceramic, cardboard, paper or the like are all suitable materials for the toilet seat. The preferred embodiment includes a toilet seat made of a material that is cost effective to be disposed after a single use (i.e. disposable) and biodegradable. Cardboard and paper are preferred materials for several additional reasons. These materials can readily be made sturdy enough to remain substantially flat surface during use while also being weak enough to permit folding after use. Furthermore, cardboard and paper are readily made to the desired shape, such as by die cutting. These materials may also readily have fold lines created through a number of techniques including die cutting, clamping or perforation. In addition, these materials readily accept adhesive and adhere with cost effective adhesives. In one preferred embodiment, the cardboard or paper toilet seat is coated with or impregnated with a water proof or water resistant material to help prevent decomposition of the toilet seat in the presence of water.
The receptacle may be attached to the toilet seat in any manner that generally insures a water tight seal between the receptacle and the toilet seat; e.g. an adhesive. The receptacle may also be heat staked or otherwise melted to attach it to the toilet seat. This may be particularly preferred when the toilet seat contains plastic or a plastic cover layer.
The receptacle may be made of any material that is capable of containing the results of the toileting functions. A relatively flexible, water proof plastic bag is preferred. In a more preferred embodiment, a clear plastic bag is utilized to facilitate visual inspection of the resultant waste by a caregiver. A variety of indicators may be utilized on the receptacle to notify when a receptacle has been used e.g. a wetness indicator.
The adhesive on the topside of the toilet seat may be spread across substantially all the area of the toilet seat or spread across only a portion of the toilet seat. Preferably, at a minimum, adhesive is applied on the toilet seat around at least half the circumference of the toilet seat. Thus, when folded, a proper seal can be insured. In a preferred embodiment, the adhesive is spread around the whole circumference of the toilet seat. The adhesive may be applied in any manner or pattern that minimizes material costs while leading to a sealed disposable hygiene device after use.
The protective layer is typically sized and shaped to conform to the size and shape of the toilet seat. However, to save materials, the protective layer may be sized and shaped to cover only those areas of the toilet seat which contain the adhesive. Furthermore, the protective layer may also include a tab, loop or other device which facilitates peeling the protective layer away from the adhesive. Such a feature may be particularly advantageous for individuals who have limited physical or cognitive abilities. The protective layer may be any suitable material that keeps the adhesive from sticking to the individual during use and preferably is a wax or plastic coated paper. While a single piece protective layer is preferred a protective layer with multiple pieces may be suitable.
Manufacture of the hygiene device may be accomplished using methods well known with the art. In one preferred embodiment, manufacturing includes layering a sheet of toilet seat material with a protective layer, where the toilet sheet material and the protective layer are at least partially separated from each other by an adhesive. Cutting the toilet seat to shape may be accomplished by die cutting or other suitable technique. Attaching the receptacle to the toilet may be accomplished with any suitable technique. There is no particular order in which the manufacturing steps need to be carried out, although layering followed by cutting followed by attaching is the preferred order.
The device may include one or more facilitating components that facilitate the toileting functions or disposable of the used device. For example, odor control may encourage an individual to use this type of hygiene device or station again. Odor control mechanism may be a part of the device such as scented material within the receptacle, as part of the receptacle material, as part of the toilet seat or as part of the peel exposed adhesive. In one embodiment, the act of removing the protective layer causes the release of covering scent. Other facilitating components include a portion of toilet tissue, sanitary wipes or gel to provide hand cleaning after use, and/or instructions on the proper use and disposal of the device. In one preferred embodiment, both toilet paper and sanitary wipes are held in a dispenser at or near the front of the toilet seat or on the extension, if present. Another facilitating device may include a hydroscopic material contained with the receptacle. Such a material may facilitate the disposal of the device.
The device may be packaged in an envelope or bag that holds the device and some or all of the facilitating components as well. The envelope may serve as an addition disposal bag into which the used device may be place along with the other used components. Such a double layer waste disposal system may be required by some municipalities for the disposal of human waste. The envelope may also be resealable. The use of an envelope also would permit the hygiene device to be easily sold in a piece by piece manner, such as in public bathrooms.
The present invention also includes a hygiene station that may be used separately or in combination with the hygiene device described above. Regardless, the hygiene stations of the present invention permit an individual to accomplish toileting functions with a good deal of dignity even if the individual is of limited mobility.
In a first embodiment, the hygiene station is intended for use by individuals that are bed bound, where the toilet is brought to the bed; the essence of a portable hygiene station. By themselves or with the help of a caregiver, an individual may place a hygiene station with a hygiene device in the bed to permit the accomplishment of toileting functions without the need to leave the bed. Referring to
In addition to the main portion 110, the hygiene station 100 also includes a wedge or ramp 116. The wedge provides a sloped incline generally from the bottom surface of the main portion to the top surface. With the incline, an individual may find it easier to maneuver into proper position to use the hygiene device. The wedge means that an individual with a minimum of upper body strength could slide themselves up the incline and into position or vice versa. In the absence of the wedge, an individual would have to lift themselves up while simultaneously sliding the hygiene device into or out of place. The wedge also means that an individual caregiver could also maneuver a user into proper position with a minimum of help from the user or from another caregiver, by either moving the individual or the device into or out of place.
The hygiene device may be made of any material sturdy enough to support the weight of the individual, such as metal or plastic. Preferably, a clear plastic is utilized to facilitate a visual inspection of the receptacle by a caregiver. The hygiene device also preferably is made of a material that resists sliding on bed linens. In the alternative, the hygiene device may include a layer or coating on its bottom surface that helps resist sliding on bed linens.
In a second embodiment, the hygiene station is intended for use by individuals that have limited walking capabilities or have limited access to traditional toilet facilities (e.g. truckers, RV-ers, campers and the like).
Referring to
The hygiene stations shown in
The hygiene stations are sized and constructed to permit easy movement of the station to and from the location where the toileting function will be carried out, whether that is bedside, within a vehicle or elsewhere. For example, the hygiene stations shown in
Although the hygiene stations shown in
In addition to the toilet, the hygiene stations may include a variety of facilitating components that facilitate the toileting functions or disposable of the used device. These facilitating components may be instead of or in addition to any such components that may be part of the hygiene device. For example, as seen in
As seen in
As seen in
Some of the facilitating components of the hygiene stations discussed above may be modular in they can be added, removed or used independently of each other, as necessity dictates. For example, as seen in
The hygiene stations are preferably used with the hygiene device; however, this is not necessarily the case. The depicted hygiene stations may include electrical and plumbing connections to the building or vehicle in which they reside. Alternately, the hygiene stations may have a self-contained source of water, a waste reservoir and/or an electrical source (e.g. a battery).
In another aspect, the present invention comprises a multi-functional hygiene station where several functions are integrated into a single unit. Referring to
The bathroom fixtures are preferably capable of at least one of the following actions to ease an individual's use of the bathroom fixtures: rotating about the central column (shown by arrows and phantom views in
The permitted movement of the bathroom fixtures eases the strain of accomplishing multiple hygiene functions at one time. For example, once seated on the toilet, the individual may rotate the sink to bring it within reach so that the individual does not need to move from the toilet to wash. In another situation, an individual can shower while seating on the toilet by rotating the shower. Height adjustable bathroom fixtures are advantageous to ease an individual's use of the fixture. For example, the sink may rise up so that an individual in a wheel can roll underneath the sink. A sink that extends from the central column would offer similar benefits to an individual in a wheel chair or an individual with a walker.
In a preferred embodiment, the sink is located above the toilet on the central column and both are rotatable and height adjustable, while the shower is rotatable. In another embodiment, the bathroom fixtures are integrated into a single platform connected to the central column where the platform is rotatable and height adjustable. In this embodiment, the central column may be located through the substantial center of the platform or may be located to provide a cantilevered platform. In another preferred embodiment, the toilet and sink are located back-to-back (as seen in
The central column of the hygiene station provides a unified connection point for the source and drain plumbing that may be used by the hygiene station. Instead of requiring hot and cold water lines for each of the toilet, sink and shower, a single set of hot and cold water lines can be provided through the central column. A similar advantage is realized with respect to the drains for the hygiene station. Such unified source and drain plumbing reduces the cost of installation and maintenance. In a preferred embodiment, all the bathroom fixture have common water source lines and at least the toilet and sink have common drain lines. Where a bathtub is included, it preferably shares a drain with the toilet and sink. In addition, a unified connection point permits a hygiene station to be modularly built in the factory or as part of the installation of the station. The unified connection point typically be at or near the floor or wall, however the connection point may be near the ceiling.
The hygiene station may also include a variety of other facilitating components that help with the toileting, washing and/or grooming functions. For example, the hygiene station may include lighting, storage, mirrors, support rails, a water collection system, a ventilation system, a heating and cooling system, a humidity control system, an audio-visual system, a monitoring system, and combinations thereof.
One example of a water collection system would be a floor pan that directs shower water to a drain with a sloped floor and/or with a barrier on the floor.
Besides entertainment, the audio-visual system may also provide task prompting to the user who may require such prompting to adequately complete toileting or other hygiene functions, such as washing, tooth brushing, etc. The audio-visual system may also provide warnings such as regarding water temperature or slick floors.
The monitoring system may include both video and audio monitoring capabilities, including items such as microphones and speakers to facilitate two-way communication between the individual using the hygiene station and a remotely located caregiver. The monitoring system may also include a call button that the individual could use to request assistance.
Doors and panels on the central column may be used to give or restrict access to the various mechanisms and components of the hygiene station. For example, a medicine cabinet door may provide an individual with access to storage, whereas a locked access panel may restrict the individual's access to the plumbing system.
In a preferred embodiment, the central column contains all of these facilitating components. As seen in
In addition to the water source and drain, the hygiene station also preferably has an electrical power source, such as being tied into the power system of the building or vehicle where the hygiene station is located. Other inputs may also be necessary, such as wire or computer cables to provide information for the audio-visual system on the hygiene station.
The base to which the central column is attached is typically a floor or ceiling, thus providing a central column that is substantially vertical. In another embodiment, the central column is attached to a wall or other vertical structure, thus providing a central column that is substantially horizontal. In either case, the base may be portable or part of a permanent structure. In addition to the roughly cylindrical shape of the central column shown in the figures, other shapes are also possible including regular and irregular polygons. In one embodiment, the central column is a partition (e.g. a C-shaped partition) or stall that provides the individual with privacy during use of a station located in a public place.
It will be further appreciated that functions or structures of a plurality of components or steps may be combined into a single component or step, or the functions or structures of one step or component may be split among plural steps or components. The present invention contemplates all of these combinations. Unless stated otherwise, dimensions and geometries of the various structures depicted herein are not intended to be restrictive of the invention, and other dimensions or geometries are possible. Plural structural components or steps can be provided by a single integrated structure or step. Alternatively, a single integrated structure or step might be divided into separate plural components or steps.
In addition, while a feature of the present invention may have been described in the context of only one of the illustrated embodiments, such feature may be combined with one or more other features of other embodiments, for any given application. For example, one possible combination would be a hygiene station that resembles the station depicted in
