Inflatable pad and methods for using the same
The inflatable pad includes an inflatable frame having a length and width that defines a pad area suitable for supporting a person lying thereon. A plurality of internal support members are configured to support the weight of a person lying thereon and elevate the person above the ground. The inflatable pad includes non-supporting regions that require less fill volume than regions that support primary support regions such as the hips and shoulder.
1. A method for using an inflatable pad comprising:
providing an inflatable pad, the inflatable pad comprising:
a frame comprising:
a first sheet of material and a second sheet of material joined at a plurality of bond lines, wherein the bond lines are elongated, wherein at least one end of at least one of the bond lines increases in width;
a plurality of fluidly coupled cells defined between at least two bond lines of the plurality of bond lines, wherein the plurality of fluidly coupled cells comprise a first width and a second width; and
a first valve coupled to the frame and in fluid communication with the plurality of fluidly coupled cells;
inflating the plurality of fluidly coupled cells to a first pressure; and
using the inflated plurality of fluidly coupled cells to elevate a person lying thereon above a surface.
2. The method of claim 1 comprising: inflating the plurality of fluidly coupled cells to the first pressure by mouth.
3. The method of claim 1 comprising: inflating the plurality of fluidly coupled cells to the first pressure by a pump.
4. The method of claim 3 comprising: inflating the inflatable pad to the first pressure of at least 2 psi.
5. The method of claim 1 comprising: inflating the plurality of fluidly coupled cells to the first pressure by mouth and to a second pressure by pump.
6. The method of claim 5 comprising: inflating the inflatable pad to the second pressure of at least 2 psi.
7. The method of claim 1 comprising: supporting the weight of a person lying on the inflatable pad.
8. The method of claim 7 comprising: providing greater support to a person lying thereon in at least one of a head region, a shoulder region, a hip region or a feet region.
9. The method of claim 1 comprising: inflating the inflatable pad to a first pressure of fill volume to pad area of 0.4-4.0 ml/cm 2 where the fill volume consists of the volume of air contained within the inflatable pad at a pressure of 2 psi.
10. The method of claim 1 comprising:
inflating a supporting region; and
inflating a non-supporting region, wherein a fill volume of the non-supporting region is less than a fill volume of the supporting region.
11. A method for using an inflatable pad comprising:
providing an inflatable pad, the inflatable pad comprising:
a pad area;
a first valve coupled to a frame and in fluid communication with a plurality of fluidly coupled cells;
the frame comprising a first sheet of fabric material and a second sheet of fabric material joined at a plurality of bond lines with at least one bond line around the entire periphery of the first sheet of fabric material and the second sheet of fabric material, wherein at least one end of at least one of the plurality of bond lines increases in width, wherein the plurality of bond lines comprise non-supporting regions;
inflating a supporting region; and
inflating the non-supporting region, wherein a fill volume of the non-supporting region is less than a fill volume of the supporting region.
12. The method of claim 11 , wherein a portion of the plurality of bond lines are non-perpendicular to the periphery of the frame.
13. The method of claim 11 , wherein the bond lines are elongated and the bond lines are longer than they are wider.
14. The method of claim 11 , wherein the non-supporting regions cover at least 25 cm 2 of the pad area.
15. The method of claim 11 comprising: inflating the plurality of fluidly coupled cells to a first pressure by mouth.
16. The method of claim 11 comprising: inflating the plurality of fluidly coupled cells to a first pressure by a pump.
17. The method of claim 16 comprising: inflating the inflatable pad to the first pressure of at least 2 psi.
18. The method of claim 15 comprising: inflating the plurality of fluidly coupled cells to a second pressure by pump.
19. The method of claim 18 comprising: inflating the inflatable pad to the second pressure of at least 2 psi.
20. The method of claim 11 comprising: supporting the weight of a person lying on the inflatable pad.
21. The method of claim 11 comprising: inflating the inflatable pad to a first pressure of fill volume to pad area of 0.4-4.0 ml/cm 2 where the fill volume consists of the volume of air contained within the inflatable pad at a pressure of 2 psi.
