FIG. 16 is top schematic view of a bi-level mattress having a head section, a foot section. - One aspect of a mattress is indicated generally in figures by
reference number 30.Mattress 30 can be comprised of individual sections, for example, threesections FIGS. 8 and 13 or two sections with a head section, 32, 34, and 38, as seen inFIGS. 9-12 or three sections and a head and afoot section FIGS. 14-16 ). The use of sections is preferable since a section can be replaced if damaged. However, the mattress can be construction as one piece, without sections. The mattress generally is molded from a plastic or vinyl material that is durable, easily and economically molded and easy to keep clean. - In any event, each section, and hence the mattress as a whole, includes a
base 41 with a plurality of linearly alignedindividual inflation cells 42 arranged across the base forming longitudinal and transverse rows of individual cells.Individual inflation cells 42, are interconnected as will be discussed in reference toFIGS. 9-16 . - As seen in
FIGS. 1-6 , amattress 30 generally will include an air source, such aspump 44 operably connected to a group of inflatable cells byhoses 46 so thatpump 44 is in fluid communication with a group of cells. Since each mattress section will have two sets of cells for alternate inflation, there are two hoses for each section. Hence, if there are three mattress sections, there would be six (6) hoses (two each section) one each of which is in fluid communication betweenpump 44 and a set of inflatable cells in a mattress section through amanifold 48. Manifold 48 can have internal valves or there can be a solenoid operated valves positioned at any operative location between the pump and a set of cells to control the inflation and deflation of selected groups of cells. - Mattress 30 also includes a
controller 50.Controller 50 can be of any design and configuration that controls the actuation ofpump 44 and the distribution of air into the sets of cells through the manifolds or solenoid valves as desired.Controller 50 can be computer operated by appropriately programmed software or can be function through the use of timers and electrical switches. It will be appreciated that the pump, controller and valve arrangement can be of any desired configuration so long as it provides the controlled inflation and deflation of groups of cells as will be described in greater detail. - As seen by comparing
FIGS. 5 and 6 , groups of interconnected cells can be inflated to form a first staggered pattern of inflated cells (FIG. 5 ) and then an alternate staggered pattern of inflated cells (FIG. 6 ). For purposes of illustration, the group of inflated cells inFIG. 5 will be referred to as Group A and the group of inflated cells inFIG. 6 will be referred to as Group B. These alternating staggered or “checkerboard” patterns diffuse load of a user positioned on the mattress over a wide area. As ill be appreciated, there is no straight lines of force. The alternating inflation patterns break up the pattern of pressure points on the user's anatomy. In other words, it increases resolution in a manner analogous to pixels on a video screen. - Referring to
FIGS. 1-6 as well asFIG. 7 , one illustrative mode of operation will be described.FIGS. 1 and 2 show the mattress in a completely deflated mode.Pump 44 is actuated and the appropriate valves are opened so that air flows into all the cells for full inflation of the mattress, as shown inFIGS. 3 and 4 . This full initial inflation is illustrated on the graphs ofFIG. 7 as A Init. Inflate and B Init Inflate. In general, when the cells are inflated, they are inflated to an optimal internal pressure that will maintain a desired interface pressure between a user's body and inflated cells over a broad range of user body sizes for example, a desired interface pressure of about 25 mmHg to about 200 mmHg, preferably between about 25 and about 80 mmHg, but preferably below the body's capillary closing pressure of about 32 to about 35 mmHg, for example about 25 mmHg. By way of example, over the broadest range of conditions, i.e. patient body mass, this may be accomplished by having an air pressure within an inflated cell of approximately 40 mmHg. Of course, the internal cell pressure can be manipulated based upon the user's body mass to arrive at an internal cell pressure that achieves a desired interface pressure. - As seen in
FIG. 7 the cells in Group A begin a slow deflation (A Deflate), for example, to an interface pressure of approximately 16 mmHg for a predetermined dwell (A Deflate Dwell). There is a predetermined dwell time for the deflated state of Group A, for example, a 60 second dwell. It will be understood that at this time, the cells in Group B remain at their initial inflation pressure. Subsequently, the cells of Group A are slowly inflated, generally at an air flow rate of about 12 ft.3/hour, to the desired interface pressure, e.g. 25 mmHg (A Inflate) and the cells in Group B begin to slowly deflate to a lower interface pressure, e.g. 16 mmHg (B Deflate) and they remain at this lower interface pressure for a predetermined dwell time (B Deflate Dwell) for example, 60 seconds and the cells in Group A remain inflated at the optimum interface pressure. The cells in Group B slowing begin to inflate (B Inflate) and when inflated, the cycle begins over again at the A Deflate line. As will be appreciated, there is a regular pattern of inflation, deflation, deflation dwell for each group of cells that achieves the staggered or checkerboard-type pattern of inflated cells at an optimal interface pressure for an optimal amount of time to achieve a desired result. -
FIGS. 8-16 illustrate schematically several alternative designs for the mattress.FIG. 8 shows a mattress having threesections cells 42 arranged across the base forming longitudinal and transverse rows of individual cells. One group ofindividual inflation cells 42, are interconnected byairflow pathways 60 and another byairflow pathways 62. As can be seen, the patterns of airflow pathways result in the inflation of the cells in an alternating or checkerboard pattern. As stated above, if there are two inflation zones in a section, then there would be two (2)hoses 46 per section, one each to deliver air to the two zones. Hence, in a mattress having three sections with two zones, there would be six hoses in fluid communication between the mattress and the pump, each controlled by a valve. -
FIG. 9 is a top schematic view of a mattress having three sections with three inflation zones per section.FIG. 10 is a top schematic view of a mattress having three sections with four inflation zones per section.FIG. 11 is a top schematic view of a mattress having ahead section 38 andside rails head section 38 does not include alternating pressure cells (i.e. no airflow pathways between the cells), since that may be an annoyance to some users. This portion is inflated and remains inflated via check valves. Side rails 63 and 64 are inflatable side rails or bolsters. They, as well as thehead section 38 are inflated by the same pump and remain inflated at a constant level. Check valves prevent deflation.FIG. 12 is another top schematic view of a mattress having ahead 38 section and with four inflation zones per section and side rails 63, 64.FIG. 13 is a top schematic view of a mattress having three sections with two inflation zones per section and side rails 62, 64 -
FIG. 14 is top schematic view of a mattress having ahead section 38, afoot section 40, and three inflation zones per section and side rails 63, 64. As with the head section and side rails, at least a portion of the foot section generally is inflated and remains at a constant pressure.FIG. 15 is top schematic view of a mattress having ahead section 38 and afoot section 40 of a different configuration The head and foot sections are comprised of elongated inflatable or tubular typeinflatable cells 65 that run transverse to the cushion itself.FIG. 16 is top schematic view of a bi-level mattress. The mattress ofFIG. 16 as shown, includes ahead section 38 andfoot section 40. In this embodiment, there is an underlying inflated mattress M that provides support in the event the alternating pressure mattress deflates. This configuration prevents bottoming out. - It will be appreciated from the foregoing that that the arrangement and configurations of the mattress with alternating pressure cells is unlimited. They can have underlying mattresses, head sections, foot sections, or side rails. They can be sectional or one piece. They can have sections that include the alternating pressure air cells or do not include the alternative pressure air cells. They can include low air loss sections as well. Any arrangement or configuration that employs the alternating pressure air cells is intended to fall within the scope of the invention.
- The rate of inflation and deflation, the internal cell pressure and interface pressure can be controlled or adjusted as desired. One skilled in the art will appreciate that individual parameters can be and will be adjusted depending upon patient size and body mass, condition of the user's skin and other factors.
- The foregoing is an illustrative embodiment of the broader invention and a best mode of operation currently known to the inventors.
