Definitions

• FIG. 3B is a partial cross-sectional view of the air bag 171 shown in FIG. 3A, including its fluidized bead pouch 172, taken along lines 3B-3B in FIG. 3A 25
• FIG. 4A is a partially-exploded perspective view of an air bag 121, which is a second
• FIG 6 is a more detailed perspective view of the mattress 320 of the alternate
• FIG 1 is considered to be a presently preferred embodiment of that invention.
• FIG 1 there is shown a patient treatment bed 20 that is uniquely suited for treatment of bum
• Air bag 121 is different, though, in that its bead pouch 122 is embodied in a removable cap 130 for air bag 121.
• the bead containment pouch 122 is removed from the air bag 121 by removing the cap 130 as a whole, so that the pouch 122 can then be disinfected or disposed of separate from any low-air-loss components.
• Other embodiments are also disclosed.
• each air bag 21, 171, 121 and 121 ' also has a post 43 and an air inlet 44 operatively secured to the bottom wall 28 thereof, as is standard for KINAIR III air bags, for attachment to the host platform 20
• Such hardware 43 and 44 are standardly employed in a manner which allows entry of air into a space 48 enclosed by the main part 29 of air bag 21, such air being blown by blowers such as standardly included in the host platform 20
• Each air bag 21 further comprises a baffle 127, also constructed of low-air-loss fabric, although less costly alternative fabrics may be desired as air permeability and low skin shear benefits are not necessary for baffle 127
• Baffle 127 functions to ensure the desired prismatic shape of the inflated bag 21 (i e , that of a rectangular prism)
• the baffle 127 is sewn, or attached by other equivalent means, at its edge 128 to the inside surface of the front side wall 23 of
• Air bag 171 is adapted with a removable bead pouch 172.
• the removable pouch 172 consists only of its upper and lower filter sheets 191 and 192 and the beads 200 contained therebetween.
• pouch 172 is inserted within (and removable from) a pocket 198' near the upper wall 177 of air bag 171. Access to the pocket 198' is provided through an opening 199 in the end wall 175 of the air bag 171.
• the opening 199 may be covered and/or sealable by a Velcro flap (not shown) or the like.
• air bag 121 also has a two-part construction adapted with a removable bead pouch 122 to facilitate infection control
• the removable pouch 122 is embodied in a removable cap 130 that fits over the top of a main part 129 of air bag 121
• the main part 129 can be disinfected through laundering in the same manner as with conventional air bags, and the cap 130 can be disinfected separately
• the particular technique used for disinfecting the cap should be chosen based on the effectiveness of each technique, it is presently thought that adequate disinfection may be achieved by placing the entire cap 130 into a conventional microsphere decontamination unit, together with a separate bead lot Such a
• decontamination is intended to raise the temperature of the cap above 120 for more than a 24-hour period
• Other disinfection techniques such as chlorination, gamma radiation and/or autoclaving, may be considered as additional alternatives
• the main part 129 of air bag 121 is much like the construction of a standard KinAir III
• the inflatable chamber serves as the plenum for fluidizing the bead pouch
• a collapsible air conduit within air bag 21 would also serve to direct the flow of air from the second air inlet to the dedicated plenum.
• conventional air conduit may be suitable, a fabric conduit (also formed of sealed low-air-loss material) may be adequate to serve this purpose.
