PORTABLE BATHING SEAT FOR BATHTUB AND SHOWER

RELATED APPLICATION

[01] The present application claims priority to U.S. provisional patent application no. 62/480, 186 filed 31 March 2017, which is incorporated herein by reference in its entirety.

GOVERNMENT RIGHTS

[02] The U.S. Government has a paid-up license in this invention and the right in limited circumstances to require the patent owner to license others on reasonable terms as provided for by the terms of Grant No. F0627-R awarded by The Department of Veterans Affairs.

BACKGROUND

[03] Field of the Invention

[04] The present disclosure generally relates to bathing devices and more particular relates to a portable bathing seat that can be used in the bathtub or shower.

[05] Related Art

[06] Devices that assist in bathing or showering are common among the elderly and disabled patient population. The National Center for Health Statistics has reported that about 10 percent of all people over the age of 65 have difficulty bathing, and about 6 percent receive help. In an assessment of home aids, adaptations and personal assistance received after traumatic spinal cord injury ("SCI") in a population of 2.5 million inhabitants in Denmark, the most common aids or adaptations reported were related to the bathtub or shower (69%). Despite the increased awareness for bathroom assistance, no room at home poses more threats to safety than the bathroom. The National Safety Council reports that 7.8% of all injury episodes in the bathroom involved persons of age 65 or older. This is because the greatest danger in the bathroom is slipping and falling when entering and exiting the bathtub or shower.

[07] To meet the needs of the aging population, the home health care services industry has grown from 40.8 million dollars in 2005 to 57.2 million dollars in 2009. Similar growth is predicted into the future based on the growing number of aging individuals entering retirement and desiring to stay within their homes. During this same period, the accessible bathtub and shower industry grew from 1 19.1 million dollars in 2005 to 148.5 million dollars in 2010. A similar growth rate was seen in the bath and pool lift industry that grew from 36.6 million dollars in 2005 to 45.6 million dollars in 2010. This growth rate of 4.5% per year is projected to continue as the boomers retire.

[08] Individuals with spinal cord injury/dysfunction confront equivalent or even more significant challenges in the bathroom. There are approximately 12,000 new cases of spinal cord injury each year. Of these injuries, 52% have tetraplegia and 45% have paraplegia (National Spinal Cord Injury Statistics Center). This level of injury leads to diminished abilities and, in some cases, individuals will require caregiver assistance for bathing and other activities of daily life. The National Spinal Cord Injury Statistics Center ("NSCISC") in Birmingham, Alabama, tracks over 91 % of this population as living in private residences. The need to remain in the home is as compelling for a spinal cord injured patient as it is for the aging because remaining in the home prolongs independence, reduces health care costs and maintains a high quality of life.

[09] Therefore, what is needed is a system and method that overcomes these significant problems found in the conventional systems as described above.

SUMMARY

[10] The present disclosure describes a portable bathing seat for use with a conventional bathtub or shower. The portable bathing seat can be used equally with a right hand or a left hand bathtub. The portable bathing seat is configured for use by non-ambulatory individuals that cannot or prefer not to sit at the bottom of a bathtub. One particular benefit of portable bathing seat is for individuals with spinal cord injury ("SCI") or other mobility dysfunctions who cannot transfer from their wheelchair to the bottom of a bathtub. The portable bathing seat is configured to rest on two or more feet where at least a first foot is inside the bathtub and at least a second foot is outside the bathtub such that the portable bathing seat straddles the rim of the bathtub. The portable bathing seat may also be positioned on the bathing surface of a shower facility. [11] The present disclosure describes a novel portable bathing seat that can be placed over a right-hand bathtub in a first embodiment or placed over a left-hand bathtub in a second embodiment and is designed for use by non-ambulatory individuals and/or individuals with SCI or other disabilities who have difficulty transferring or cannot transfer to the bottom of a standard bathtub or have difficulty standing or cannot stand in the shower during bathing periods. The portable bathing seat rests on two or more feet where at least a first foot is inside the bathtub and at least a second foot is outside the bathtub such that the portable bathing seat straddles the rim of the bathtub. Alternatively, the portable bathing seat may be placed on the floor surface of a shower stall. Whether in the bathtub or the shower, the portable bathing seat assists in the bathing of individuals within a home or other facility. The portable bathing seat contains several features that assist users in transferring safely from a standing position or from a wheelchair onto the portable bathing seat. These features include a transfer surface at a height similar to wheelchair height, an angled transfer pommel to facilitate transfer from a wheelchair onto the portable bathing seat, height adjustable legs, and a ballast reservoir for stability. Additional features are incorporated into the functionality of the portable bathing seat that facilitate an easy bathing process, including: a contoured and angled backrest with a drainage trough, a seat cushion with drainage cutout corresponding to a drainage depression in the surface of the portable bathing seat, and structural kiss-offs in the ballast reservoir for added stability.

[12] Certain advantages of the portable bathing seat include that it is configured for ambulatory access or wheelchair level transfer, configured in alternative embodiments to be placed over a right hand or a left hand bathtub, configured to fit a variety of standard bathtub widths and shower stall widths, configured with a contoured backrest, and configured to drain fluids onto the floor surface of the bathtub or shower.

An optional ballast reservoir fill hole 151 and corresponding ballast reservoir fill hole plug 152 are positioned near the handle 1 10.

[93] FIGS. 1 1A - 1 1 D are perspective view diagrams illustrating an example bather 200 transferring from a wheelchair 210 onto the portable bathing seat 10 according to an embodiment of the invention. In the illustrated embodiment, the portable bathing seat 10 is positioned with two of four feet on the bathing surface of a bathtub and with two of four feet on the floor surface 80 adjacent to the bathtub. The legs 30 of the portable bathing seat 10 are adjusted so that each foot 35 engages the bathing surface 40 or the floor surface 80 to position the platform 20 in a level orientation. Moreover, the portable bathing seat 10 is positioned such that the transfer area 120 is substantially level to the height of the seating surface of the wheelchair 210 to facilitate a simple transfer of the bather 200 from the wheelchair 210 to the portable bathing seat 10. The transfer pommel 100 is advantageously positioned to allow the bather 200 to grasp the transfer pommel 100 while the bather 200 is still in the wheelchair 210. Additionally, the surface of the transfer area 120 extends over the outer edge 70 of the bathtub to allow the bather 200 to slide directly onto the surface of the transfer area 120 from the wheelchair 210. Once the bather 200 is initially positioned on the surface of the transfer area 120, the bather 200 can reach out and grasp the handle 1 10 with a first hand and reach out and simultaneously grasp the transfer pommel 100 with a second hand and slide onto the main bathing surface of portable bathing platform 10, which is substantially directly above the bathing surface 40.
