1. Technical Field
The invention relates generally to the field of healthcare devices to be used by home-based persons with limited mobility. More specifically, the invention is directed to an improved portable shower device that is light weight and small enough such that a single person can maneuver it through standard residential doorways and into such areas of the home for convenient use by persons with limited mobility.
2. Description of Prior Art
Portable shower devices are known in the art. Some examples emphasize the portability aspects of the devices, disclosing easily disassembled devices which can be transported in carrying cases. See, e.g., Patterson, et al., U.S. Pat. No. 4,975,992 (Dec. 11, 1990), “Portable Shower Stall”, which discloses a portable shower stall having a ceiling and a base, designed to be carried in a suitcase. It features a means for connecting the device to a sink faucet and a sump pump for removing waste water. The device must be assembled for use and disassembled for portability. See also Roberts, U.S. Pat. No. 5,544,369 (Aug. 13, 1996), “Portable Shower/Multi Use Stall”, which discloses a shower stall which is disassembled for storage and reassembled for use. It features an optional holding tank for containing waste water. See also The SHS-2 Shower Stall™ by Shower Anywhere of Temecula, Calif., which discloses a shower stall which may be disassembled for portability. None of these devices have wheels or other means for assisting with movement. Moreover, they all lack the utility of the present invention, which comes fully assembled and due to its rigid construction is suitable for use by mobility impaired persons.
Other known devices are sturdier and intended to assist those with mobility impairments. See, e.g., Reid, U.S. Pat. No. 6,374,434 (Apr. 23, 2002), “Therapeutic Shower”, which discloses a horizontally oriented compartment into which a wheeled chair is rolled. The bathing function occurs within the compartment by built-in water jets. Unlike the present invention, Reid is not intended to be used to bathe the head or upper torso, and the seat is not affixed to the compartment, thereby increasing the risk of injury to the bather. See also Queen, et al., U.S. Pat. No. 5,978,983 (Nov. 9, 1999), “Portable Showering Cabinet”, discloses a portable showering device directed towards use by the mobility impaired. While it shares several features with the present invention, for example a built-in seat and casters for repositioning the device, it is a far more complicated device involving hydraulic lifting means for the seat and multiple shower heads. These overly complicated devices cannot be manufactured as inexpensively as the present invention and therefore cannot provide the universality of use as does the present invention.
Yet other devices achieve partial portability without providing all the benefits of the present invention. See, e.g., Storm, U.S. Pat. No. 6,516,477 (Feb. 11, 2003), “Shower Apparatus for Seated Occupant”, discloses a device intended to be used in conjunction with a standard toilet. As such, it lacks the complete portability of the present invention, which can be used in locations not having a toilet, such as a bedroom.
Thus none of the disclosed prior art anticipates the present invention.
It is an objective of the present invention to provide a useful, improved portable shower device that is suitably adapted to be used to administer a shower to a person with limited mobility.
It is an objective of the present invention to provide a useful, improved portable shower device that is light weight and can be easily moved by one person to a convenient location.
It is a further objective of the present invention to provide a useful, improved portable shower device that can be moved through standard residential doorways.
It is a further objective of the present invention to provide a useful, improved portable shower device that can be safely used by the person receiving the shower or by a second person administering the shower.
It is a further objective of the present invention to provide a useful, improved portable shower device that can be quickly connected to a standard sink faucet for use, and then easily disconnected when no longer being used so that the faucet may be used for other purposes.
It is a further objective of the present invention to provide a useful, improved portable shower device that can be used in locations having no access to waste water disposal facilities.
It is a further objective of the present invention to provide a useful, improved portable shower device that does not require assembly by the user.
It is a further objective of the present invention to provide a useful, improved portable shower device that is easy and inexpensive to manufacture.
Other objectives of the present invention will be readily apparent from the description that follows.
The present invention is a portable shower device created for people who are unable to use conventional bathing facilities due to restricted mobility. This would include people who are unable to navigate stairs to get to their bath/shower, or those who are unable to use conventional facilities for other reasons. The usual alternative for these folks is sponge bathing. The present invention can easily be moved to a convenient location due to its light weight and then stored out of the way when not in use. The bather may be assisted by a home health care provider to enter and exit the unit and who may also assist in bathing.
The preferred embodiment of the present invention comprises a water tight cabinet with a built-in seat. It can easily be brought into a home through the front door and has wheels or casters and handles that make it easy to deliver and move about. Water is provided through an inflow hose attached to a sink faucet with a quick connect coupling. Water is directed into the cabinet and onto the bather through a delivery hose having a hand held shower head. Waste water is removed through a drain in the floor by an electric pump, which empties the waste water through an outflow hose back into the sink drain. The cabinet has interior grab rails for safety and a shower curtain to accommodate entrance and exit.
As will be readily evident from the following detailed description and the accompanying claims, the present invention may have other uses beyond providing a means for addressing the hygiene of persons with limited mobility. For example, the present invention may be used as a temporary camp shower or wherever a permanent facility is not available or desired.
Other features and advantages of the invention are described below
The portable shower device 1 of the present invention comprises three principle components: a cabinet 100, a fluid inflow means 200, and a waste fluid handling means 300. See
The cabinet 100 must be suitably adapted to permit a person to be at least partially contained within its interior 122, for purposes of receiving a shower. The cabinet 100 must be substantially water-tight, such that fluids directed into the interior portion 122 of the cabinet 100 during the provision of a shower are substantially contained by the cabinet 100, except as such fluids are removed from the cabinet 100 by the waste fluid handling means 300. Some escape of fluids from the cabinet 100 is expected during showering, however, given that the cabinet 100 is not enclosed over its top and thus some splashing of fluids against the person receiving the shower may occur, but this escape of fluids would be minimal. To achieve the primary goals of the invention, the cabinet 100 must be suitably dimensioned to fit through a standard residential doorway, and be light enough to be moved by one person. As such, in the preferred embodiment the cabinet 100 has a width of no greater than thirty-six (36) inches, a height of between thirty (30) and fifty-four (54) inches, and weighs no more than one hundred (100) pounds. In the most preferred embodiment the cabinet 100 has a width of thirty (30) inches, a height of forty-eight (48) inches, and weighs between fifty (50) and seventy-five (75) pounds.
The fluid inflow means 200 must be suitably adapted to convey fluid 410 from a fluid source 420 into the interior 122 of the cabinet 100, thus providing the fluid 410 necessary for a shower. The fluid inflow means 200 is removably connectable to the fluid source 420. The preferred embodiment contemplates the fluid source 420 to be a standard sink, and the fluid inflow means 200 is connected to the faucet 450 of the sink by any non-permanent means known in the art. Operation of the sink causes water to flow through the fluid inflow means 200 to be conveyed into the cabinet 100. When the portable shower device 1 is not being used, the fluid inflow means 200 is disconnected from the water source, which can then be used for other purposes.
The waste fluid handling means 300 must be suitably adapted to convey fluid 410 out of the interior 122 of the cabinet 100. Waste fluids may be conveyed into an intermediate holding tank 320 or completely out of the portable shower device 1. It is anticipated that the waste fluid handling means 300 may discharge waste fluids into a standard home toilet, or a bathtub, or a sink, though it may discharge waste fluids into a floor drain or into a portable receptacle, such as a bucket. The flow of waste fluids through the waste fluid handling means 300 may be directed by gravity or may be assisted by a pumping device 340.
The cabinet 100 must comprise the following subcomponents: a floor 110, a side wall structure 120, an exterior surface 130, a seat 140, and an access means 150. See
The side wall structure 120 of the cabinet 100 is adjacent to the floor 110 and oriented substantially vertically. In the preferred embodiment the floor 110 and side wall structure 120 are integrated with each other, thereby forming an open-ended enclosure, with the interior 122 of the cabinet 100 defined by the floor 110 and side wall structure 120. The side wall structure 120 must be substantially rigid and may have any suitable configuration, but in the preferred embodiment the side wall structure 120 comprises four side walls, each side wall being substantially planar and each side wall being substantially perpendicular to its adjacent side walls, thereby forming a rectangular enclosure. In other embodiments the side wall structure 120 may have a curved shape, thereby creating a cylindrical or ovoid or elliptical enclosure, or may have a combination of curved and planar surfaces.
In an alternative embodiment, the side wall structure 120 of the cabinet 100 comprises an extension means to vertically extend the height of at least a portion of the side wall structure 120. The extension means may be adjustable. One embodiment of the extension means comprises one or more shower curtains and a shower curtain support structure attached to the side wall structure 120. The extension means are useful to add privacy to a person capable of administering a shower to him- or herself, while it can be lowered or removed where a caregiver is needed to administer the shower.
The exterior surface 130 of the cabinet 100 may be of any suitable material, including thermoformed plastic, acrylic, fiberglass, rigid foam, epoxy, gel-coat, or wood. The exterior surface 130 should be scuff and dent resistant. In the preferred embodiment the cabinet 100 comprises at least one grab bar 184 located on the exterior surface 130, suitably adapted to be gripped by a person to assist that person in moving the cabinet 100. In the most preferred embodiment the cabinet 100 comprises several grab bars 184 located about the exterior surface 130. In another embodiment the cabinet 100 further comprises at least one storage compartment located on the exterior surface 130 of the cabinet 100. This storage compartment may contain items of use to the showering process, such as soap, shampoo, wash cloths, and the like, or may contain various components of the fluid inflow means 200 when the portable shower device 1 is not being used. In yet another embodiment multiple storage compartments may be located on the exterior surface 130 of the cabinet 100.
The cabinet 100 must have an access means 150 suitably adapted to allow a person to enter into the interior 122 of the cabinet 100. The access means 150 is integrated with the side wall structure 120 of the cabinet 100, and comprises at least an aperture 152 and a means for covering and uncovering the aperture 152. The aperture 152 may be of any suitable shape, but in the preferred embodiment is substantially rectangular. In one embodiment the access means 150 utilizes a hinged door to cover and uncover the aperture 152. The door is attached to the side wall structure 120 and suitably adapted to be positionable between an open position and a closed position, whereby when in the open position the door uncovers the aperture 152 sufficiently to allow a person to pass through the aperture 152 and enter into the interior 122 of the cabinet 100, and when in the closed position the door substantially covers the aperture 152 and prevents the escape of fluids from the interior 122 of the cabinet 100 through the aperture 152. In another embodiment the access means 150 utilizes a drop-in panel to cover and uncover the aperture 152. The panel is removably attachable to the side wall structure 120 by inserting it into or removing it from grooves integrated into the lateral sides of the aperture 152. In the preferred embodiment the access means 150 utilizes a shower curtain 154 to cover and uncover the aperture 152. See
The cabinet 100 must comprise a seat 140, located within the interior 122 of the cabinet 100. See
In the preferred embodiment, the cabinet 100 comprises a liner 160. See
In one embodiment, the liner 160 is a monolithic unit constructed of thermoformed plastic, acrylic, fiberglass, rigid foam, epoxy, or gel-coat. In the preferred embodiment the liner 160 is constructed of thermoformed acrylic. This embodiment allows for ease of manufacture and water-tight construction. When so configured, the liner 160 may be sufficiently rigid to comprise the entire structure of the cabinet 100. In an alternative embodiment, the liner 160 may be supported and reinforced by a frame 170. See
In one embodiment of the present invention, the cabinet 100 comprises at least one grab rail 182 located within the interior 122 of the cabinet 100. See
In order to facilitate the goal of portability, the cabinet 100 comprises a movement means. The movement means is located on the underside of the cabinet 100 and suitably adapted to ease movement of the portable shower device 1 over floors or the ground. The movement means may be wheels 190, see
The fluid inflow means 200 may comprise the following subcomponents: an inflow conduit means 210, a connection means 220, and a fluid delivery means 230. See
In the preferred embodiment the inflow conduit means 210 is a single flexible hose 212. The flexible hose 212 may be removably connected to a standard sink faucet 450, whereby the temperature and volume of water to be used for showering is controlled by using the faucet controls. See
In an alternative embodiment the inflow conduit means 210 comprises a first flexible hose 214 and a second flexible hose 216. See
In the preferred embodiment, the connection means 220 for removably connecting the fluid inflow means 200 to a water source comprises a quick connect coupling 222 suitably adapted to be removably attached to a standard sink faucet 450. Such quick connect couplings 222 are well-known in the art and are typically utilized with portable dishwashing machines. Two quick connect couplings 222 may be used, one for each flexible hose 214,216, when the dual water source configuration described above is employed.
The fluid delivery means 230 of the fluid inflow means 200 may comprise a delivery hose 236. The delivery hose 236 is connected to the inflow conduit means 210 and is suitably adapted to deliver fluid 410 from the inflow conduit means 210 into the interior 122 of the cabinet 100. The delivery hose 236 may be connected to the inflow conduit means 210 by a coupler located within the side wall structure 120 of the cabinet 100. In this embodiment the inflow conduit means 210 attaches to the coupler from the exterior of the cabinet 100, and the delivery hose 236 attaches to the coupler from the interior 122 of the cabinet 100. In another embodiment the delivery hose 236 attaches to the coupler within an exterior storage compartment of the cabinet 100, where it may be stored when not in use. This configuration minimizes the overall length of the free moving portion of the fluid delivery means 230, limiting it to the delivery hose 236. That is, in this configuration the inflow conduit means 210 is fixed to the cabinet 100 and thus need not be manipulated by the user while administering a shower, thereby making use of the portable shower device 1 more convenient. In one embodiment, the fluid inflow means 200 may comprise a pressure reducing device. The pressure reducing device is suitably adapted to reduce the pressure of the fluid delivered to the delivery hose 236 by the inflow conduit means 210. This is to prevent excess water pressure from a water source from causing discomfort or even harm to the person receiving the shower. The pressure reducing device may be located in-line the coupler. An on/off controller 234 suitably adapted to be operated by a human hand and suitably adapted to either permit the flow of fluid 410 through the delivery hose 236 or to prevent the flow of fluid 410 through the delivery hose 236 may be integrated into the cabinet 100 side wall structure 120.
The fluid delivery means 230 of the fluid inflow means 200 may also comprise a shower head 240 attached to the end of a delivery hose 236. See
The waste fluid handling means 300 may comprise the following subcomponents: a drain 310 and a conduit means 330 connected to the drain 310. See
In the preferred embodiment the waste fluid handling means 300 comprises a pump 340. See
In another embodiment, the waste fluid handling means 300 may comprise the following subcomponents: a drain 310, a holding tank 320, and a conduit means 330 connecting the drain 310 to the holding tank 320. See
In another embodiment there is an outflow conduit 350 connected to the holding tank 320. See
Modifications and variations can be made to the disclosed embodiments of the invention without departing from the subject or spirit of the invention.
