Abstract: There are many types of bariatric lift apparatuses. Some of the present designs are inherently unstable in nature because of their basic design philosophy. Others are extremely large and bulky and can not be used effectively in the bariatric patient's living quarters. In others there is inability to transfer bariatric patients from certain type of beds or other furniture items because the devices contain certain obstacles which are inherent to their design. One of the functions of the apparatus is to provide controlled unassisted transfer from the bed to the apparatus. The inability of some bariatric patients to provide any self induced lifting in a normal manner is a major limiting feature of present-day gurney and/or lift chair designs. As the obesity rate climbs nationwide, obese and morbidly obese patients will continue to pose special lifting challenges to the healthcare industry.

Abstract: Advances in robotics have had a great influence in the design and performance of motorized assistive devices in the past two decades. Specifically, introduction of “intelligent” system technologies has enabled users of motorized assistive devices to better control their machines and avoid problematic situations. However, one area of assistive devices that has not reaped the benefits of advances in the state-of-the-art, is major weight reduction in the overall design of these devices. Bulky motorized assistive devices hinder the range and portability of these devices and impact the ability of the user to manually handle these devices without assistance of mechanical lifting devices or individuals. This ultralight, collapsible powered operated vehicle (POV) is lighter than those available today by approximately 80%. This device addresses this issue by the development of an ultralight, collapsible POV, which will replace the bulky and heavy motorized assistive devices currently being used.

Abstract: The invention uses specialized wheel sets to navigate over various surfaces. The invention has a primary drive wheel with two outrigger wheels to provide stability. In the basic motorized configuration of the apparatus, the user provides certain hand movements of the control mechanism, which in turn produces control signal(s). Incorporated into the invention is a power lifting mechanism, which aids the user to be elevated from a seated position to a standing position without any assistance. A built-in seat is incorporated within the invention. The built-in seat is a fold down type that is adjustable in height. In the virtual mode, various user motion signals are relayed, by wireless means, to an embedded computer module, within the apparatus. This embedded computer provides control signals to operate the invention. For ease of transport and erection, retractable/deployable units are incorporated into the design of the invention.

Abstract: As the obesity rate climbs nationwide, obese and morbidly obese patients will continue to pose special lifting challenges to the healthcare industry. Obesity among American adults has nearly doubled during the past two decades. One in 80 men weights >300 pounds and one in 200 women weights >300 pounds. Getting assistance is crucial when moving these patients. With these rising numbers, have come the numerous complications relating to medical treatment for these bariatric patients. Healthcare providers must consider the additional costs associated with handling of the bariatric patient along with safety issues relating to both the bariatric patient and caregiver. Also, moving extremely obese patients can prove to very dangerous or even fatal. The most economical assistance to move bariatric patients to and from the hospital bed can only be provided by some mechanical aid.
