Benefits of technology
[0012] The present invention overcomes the aforementioned disadvantages by providing an inflatable device that produces a forward pitch level of approximately 30 degrees that is sufficient to produce the desired effect. In addition, the degree of inclination can be achieved by an approximate 7 inch elevation of the dorsal plane of the seated position over the ventral plane. This effect can be accentuated by a 2 inch elevation of the seat cushion itself. The positional change produced by this device thus mimics the initial movements of the unassisted rise from a seated position in a normal circumstance. Therefore, performance of the initial movement by the device allows the completion of the standing process by the user.
[0015] It is yet another object of the present invention to provide an inflatable lift device that is portable and lightweight.
[0016] It is yet another object of the present invention to provide an inflatable lift device with one embodiment that contains a single valve for inflation and rapid deflation.
Problems solved by technology
Also, not the least of the inevitable effects of aging is the loss of lean body (muscle) mass with the result of muscle weakness.
A consistent feature of early impairment of mobility is difficulty in getting up from a chair.
Weakness of the extensors of the knee (the quadriceps femoris) results in difficulty rising from a chair, stair climbing and even walking.
Limitations in those functions contribute to further activity restrictions which in turn result in progressive muscle weakness.
Progressive limitations of physical activity complete a cycle of physical deterioration and diminishing lifestyle.
Although inflation of the air bag in Porché better mimics the initial movement of a seated individual as he or she begins to stand, the angle of pitch is not sufficient to fully assist the individual to stand from a seated position.
The devises of these patents, however, do not provide a means for a washable fabric cover or the ability to place the compressor within a pocket or compartment on either side of the bladder.

Embodiment Construction
[0027] Referring now to the drawings wherein the showings are for purposes of illustrating a preferred embodiment of the invention only and not for purposes of limiting the same, FIGS. 1 and 2 show an air lift seat apparatus 10 that includes a base 12, a bladder 14, an intake / exhaust valve 16, a pocket or compartment 18, a self-contained air compressor 20 and a removable cover 22 (FIG. 2). The base 12 is preferably made of a rigid polystyrene material to provide stability to the apparatus when placed on a chair. The base 12 has a front 24, a back 26 and two sides 28, 29 and is preferably about 18 inches wide, 18 inches deep and 1 inch in height. However, the base 12 can be any suitable size to fit a standard sized chair, seat cushion of a sofa or similar type of sitting apparatus as along as chosen with sound engineering judgment.
[0028] Referring now to FIGS. 2 and 3, in the preferred embodiment a connecting means 27 is provided to selectively attach the cover 22 to the base 12. Th...

A lightweight and portable pneumatic lifting device includes an inflatable, trapezoidal side shaped and self-contained bladder housed in a removable, washable material. The inferior surface of the bladder contains a rigid base for stability. Located on one side of the bladder is a compartment to house the self-contained air compressor. A valve or valves is provided for inflation and deflation of the bladder.
Description
BACKGROUND OF THE INVENTION [0001] A. Field of Invention [0002] The present invention relates to the field of medical devices and, more specifically, to an inflatable device used to assist an invalid or physically disadvantaged person in moving from a seated position to a standing position. [0003] B. Description of the Related Art [0004] The impact of the aging population of the United States is well recognized and has profound socioeconomic implications, not the least of which is the conversion of nursing home care into a major industry. Also, not the least of the inevitable effects of aging is the loss of lean body (muscle) mass with the result of muscle weakness. There are several contributing factors involve in this loss. Loss of appetite, poor dentition, lack of exercise, dwindling blood supply (particularly to the lower extremities) and down regulation of metabolism are all conspirators in this process. While these factors can be offset by improved nutrition and regulated exer...
