TH5452Y - Air bags that restrict the direction of inflation for use with mattress pads to prevent pressure sores. - Google Patents

Abstract

DC60 (15/09/52) This invention relates to a directionally inflated air sac consisting of a top wall, side wall, bottom wall, and an air inlet on one of the side walls. It has an internal core assembly with at least two lobes, or at least the same number as the side walls of the air sac. One end of each lobe connects the inner side of the side wall to the central core, restricting inflation to the top and limiting lateral expansion. The top wall can be made of a low-permeability material to improve the chances of pressure ulcer healing by increasing skin oxygen contact. This directionally inflated air sac is used with a mattress pad to prevent pressure ulcers in various alternating patterns. Each directionally inflated air sac is attached to a removable, form-fitting bottom pad that does not deform the pad when inflated. The alternating up-and-down pattern of the air sac can be adjusted in various ways, with a control unit to increase the number of alternating patterns to more than two. This directionally inflated air sac... It can also be applied to certain types of therapeutic pillows where, when the air bladder is inflated, it does not lose its shape in the desired direction. It can also be used as a cushion for massage chairs and wheelchairs, meeting various user needs. Furthermore, it is lightweight and can be disassembled as needed. When an air bladder is damaged, only that specific bladder can be replaced, making it easy to move and use. It can be placed on a standard hospital bed or on the floor and is easy to store. This invention involves a directional-limiting inflatable air bladder consisting of a top wall, side walls, a bottom wall, and an air inlet on one of the side walls. It also has an internal core assembly with at least two lobes, or at least the same number as the side walls of the air bladder. One end of each lobe connects the inside of the side wall to the central core, limiting the inflation to the top and restricting lateral expansion. The top wall can be made of a material that allows minimal air leakage, increasing the chances of pressure ulcer healing by ensuring skin contact with oxygen. This directional-limiting inflatable air bladder is used in mattress pads to prevent various types of alternating pressure ulcers. Each inflatable air bladder is attached to a removable, form-fitting bottom pad. When inflated, it maintains the pad's shape. The alternating up-and-down air bladder pattern can be adjusted in various ways, with control units allowing for more than two alternating patterns. This directional air bladder system can also be applied to certain types of therapeutic pillows that maintain their shape when inflated, and can be used as cushions for massage chairs and wheelchairs. It offers versatile functionality, is lightweight, and easily assembled and disassembled. Damaged air bladders can be replaced individually, making it portable and convenient for use on standard hospital beds or on the floor, as well as for storage.

Claims (8)

1. An air-containing defibrillator (1) for use with a mattress to prevent pressure ulcers consists of an upper wall (2) which is rectangular in shape, part of which is connected to a side wall (3), one side of which is fitted with an air inlet (8), and the lower part is connected to the lower wall (4). Specifically, the inside of the air-containing defibrillator (1) is fitted with an inner core assembly (5) which has at least two lobes (6), or at least the same number as the side walls (3), one end of which is connected between the inside of the side walls (3) and the central lobes (501) of the inner core assembly (5). 2. An air bag that restricts the direction of inflation for use with a mattress to prevent pressure ulcers, in accordance with claim 1, where the top (2) and bottom (4) walls are polygonal in shape. 3. An air bag that restricts the direction of inflation for use with a mattress to prevent pressure sores, according to claim 2, where the top (2) and bottom (4) walls are of the shape of a triangle, square, pentagon, or hexagon. 4. An air bag that restricts the direction of inflation for use with a mattress to prevent pressure ulcers, according to claim 1, where the top (2) and bottom (4) walls are circular in shape. 5. An air bag that restricts the direction of inflation for use with a mattress to prevent pressure sores, according to claim 1, where the top wall (2) is made of a different material than the side walls (3) and bottom wall (4), and such material allows a small amount of air to pass through. 6. An inflated air bladder for use with a mattress to prevent pressure ulcers according to Patent 1, in which the lower wall (4) of the inflated air bladder (1) is fitted with several sets of Velcro (15), which are attached to the underside of the mattress (10) of the mattress (9) with another set of Velcro (15). 7. An air bag with restricted inflation direction for use with a mattress to prevent pressure ulcers according to Patent 1, in which the air inlet (8) is connected to an air duct (11) in which the duct receives air from an air source (14) through an air control (12) and an air switch (13). 8. An air bag that restricts the inflation direction for use with a pressure ulcer prevention mattress according to Patent 1, in which the air bag can be alternated in ascending and descending by connecting the air tubes (11) to the air inlet (8) of the air bag that restricts the inflation direction (1), separating the air tubes (11) according to the number of sets of air system operation required by the air switch (13), and using the air system control (12) to switch the system operation and connect to the air source (14) to supply air to the pressure ulcer prevention mattress system in various alternating modes.
