Abstract
Description
- The subject matter described herein relates to mattress toppers of the kind used in connection with beds, in particular a microclimate control topper having features for preferentially distributing fluid flowing through the topper to locations where fluid flow is expected to be of most benefit to an occupant of the bed.
- Microclimate control toppers are typically used in conjunction with the mattresses of beds found in hospitals, nursing homes, other health care facilities, or in home care settings. The topper rests atop the mattress and is secured thereto by, for example, straps, snaps or zippers, or may be more permanently integrated into the mattress, for example by stitching or welds appropriate to the materials from which the mattress and topper are made. A fluid flowpath having an inlet and an outlet extends through the interior of the topper. A pump or similar device supplies a stream of air to the topper so that the air flows into the flowpath by way of the inlet, flows through the flowpath, and exhausts from the flowpath by way of the outlet. The airstream establishes a microclimate in the vicinity of the occupant's skin. Specifically, the airstream helps cool the occupant's skin thereby reducing its nutrient requirements at a time when it is compressed by the occupant's weight and therefore likely to be poorly perfused. The airstream also helps reduce humidity in the vicinity of the occupant's skin thus combatting the tendency of the skin to become moist and soft and therefore susceptible to breakdown.
- The need for microclimate control is not uniformly distributed over the occupant's skin. For example skin temperature on the occupant's torso can be considerably higher than skin temperature on the occupant's arms and legs. In addition, nonuniform distribution of sweat glands causes perspiration to accumulate on the skin of the occupant's back and pelvic region. Moreover, many modern beds are profile adjustable. When the bed profile is adjusted the occupant's tissue is exposed to shear which distorts the vasculature and further degrades perfusion.
- The present application discloses a topper for a bed. The topper extends in longitudinal and lateral directions and includes a fluid flowpath for channeling fluid through the topper from an inlet to an outlet. The flowpath is configured to distribute the fluid to a preferred target region of the topper. The application also discloses a bed which includes the topper and a blower connected to the topper inlet for supplying air to the flowpath.
- The foregoing and other features of the variants of the topper described herein will become more apparent from the following detailed description and the accompanying drawings in which:

FIG. 30 is a plan view similar to that ofFIG. 29 showing counterflowing, laterally extending passages with a central bulge so that the passages, taken collectively, define a two-sided keyhole configuration. -
FIGS. 1-4 show aconventional topper 20 resting atop amattress 24. The topper extends longitudinally from ahead end 26 to afoot end 28 and spans laterally from aleft side 32 to aright side 34. A longitudinally extendingcenterline 40 andcenterplane 42 and aspanwise centerplane 44 are shown for reference. The topper has an upper oroccupant side surface 46 and a lower ormattress side surface 48. Atarget region 50 onupper surface 46 is a region corresponding to a portion of an occupant's body judged to be especially needful of local climate control. The illustrated target region corresponds approximately to the torso of a representative patient lying face up (supine) and centered on the topper. Afluid flowpath 60 having aninlet 62 and anoutlet 64 spans laterally across the topper from itsleft side 32 to itsright side 34 and extends longitudinally through the topper. Ablower 72 or similar device is connected to the inlet by ahose 74 having ablower end 76 and atopper end 78 so that the blower can impel astream 88 of air to flow through the flowpath. The illustrated topper has no provisions for preferentially directingairstream 88 or any portion thereof to the target region. In particular, the airstream can spread out laterally across the entire span S of the topper through the entire longitudinal length of the topper. -
FIG. 5 shows an embodiment of aninnovative topper 38 for a bed. As with the previously described topper the improved topper is configured to rest atop a mattress such asmattress 24 ofFIGS. 1 , 3 and 4. The topper extends in longitudinal and lateral directions and includes afluid flowpath 60 for channeling a stream ofair 88 through the topper from aninlet 62 to anoutlet 64. In the illustratedtopper inlet 62 is a pair of inlet ports at the foot end of the topper andoutlet 64 is a wide vent opening at the head end of the topper. Other inlet and outlet designs may be used. Unlike the topper ofFIGS. 1-4 , the topper ofFIG. 5 is configured to distribute air flowing through the flowpath to apreferred target region 50 of the topper, specifically aregion 50 corresponding approximately to the torso of a supine person substantially laterally centered on the topper, although other target regions can be defined, if desired. In particular, the topper includes left andright margins flowpath 60. As aresult airstream 88 cannot spread across the entire span S of the topper but instead is confined to span S1 through the entire longitudinal length of the topper. As a result the airstream is more concentrated under the target region than is the case with the conventional topper ofFIGS. 1-4 . -
FIG. 6 is a cross section in the direction 6-6 ofFIG. 5 showing a first alternative construction of the topper. The topper comprises acentral region 96 corresponding toflowpath 60 and themargins seam 98. Example margins include foam or an inflated static bladder, i.e. a bladder through which air does not flow. The nature ofseam 98 depends on the materials used to make the central region and margins. -
FIGS. 7A and 7B are cross sections in the direction 7-7 ofFIG. 5 showing two variants of a second alternative construction of the topper. In the second alternative,central region 96, which corresponds to flowpath 60, andmargins insert 100 enclosed by a ticking 104 (FIG. 7A ) or covered by a ticking 104 (FIG. 7B ). The central region and margins are attached to each other at aseam 98 or other suitable connection. -
FIG. 8 shows another topper configured to distribute air flowing through the flowpath to preferredtarget region 50 of the topper. In particular, the topper includes left and rightarcuate margins flowpath 60. The margins converge toward each other with increasing distance from the head and foot ends 26, 28 of the topper to define a throat T (coincident with section lines 9-9 and 11-11). As a result of the flowpath shape arising from the curved borders,airstream 88 is more concentrated under the target region than is the case with the conventional topper ofFIGS. 1-4 . -
FIGS. 9 and 10 are cross sections taken along section lines 9-9 and 10-10 ofFIG. 8 and correspond to the first alternative construction shown inFIG. 6 .FIGS. 11 and 12 are cross sections taken along section lines 11-11 and 12-12 ofFIG. 8 and correspond to the second alternative construction shown inFIG. 7A . -
FIG. 13 shows an embodiment in which the margins diverge away from each other with increasing distance from the head and foot ends 26, 28 of the topper. The resulting flowpath allows airstream to diffuse laterally as it moves frominlet 62 toward plane 106 of maximum flowpath cross section and then to accelerate as it flows from plane 106 tooutlet 64. -
FIG. 14 shows an embodiment having adual inlets 62 anddual intake conduits 110 for channelingairstream 88 to a workingregion 112 of the flowpath, and asingle outlet 64 and asingle discharge conduit 114 for exhausting the airstream from the working region. The working region corresponds approximately to the target region which may correspond to the torso of a supine person substantially laterally centered on the topper. -
FIG. 15 shows an embodiment similar to that ofFIG. 14 but havingdual outlets 64 and a pair ofdischarge conduits 114 for channelingairstream 88 away from workingregion 112 of the flowpath. The working region corresponds approximately to thetarget region 50 which may correspond to the torso of a supine person substantially laterally centered on the topper. -
FIG. 16 shows an embodiment having asingle inlet 62 and asingle intake conduit 110 for channelingairstream 88 to workingregion 112 and asingle outlet 64 and asingle discharge conduit 114 for exhausting the airstream from the working region. The working region corresponds approximately to the target region which may correspond to the torso of a supine person substantially laterally centered on the topper. Unlike the embodiments ofFIGS. 5-15 in which the flowpath is symmetric with respect tocenterplane 42, the flowpath ofFIG. 16 is asymmetric with respect tocenterplane 42. -
FIG. 17 shows an embodiment similar to that ofFIG. 8 but withdual inlets 62 and a longitudinally foreshortenedflowpath 60. -
FIG. 18 shows an embodiment similar to that ofFIG. 17 but with a workingregion 112 having an arched planform and adischarge conduit 114 extending obliquely from the target region. -
FIG. 19 shows an embodiment similar to that ofFIG. 18 but with a workingregion 112 having a rectangular planform. -
FIGS. 20 and 21 show a topper in which flowpath 60 is divided into a set of five longitudinally extending, laterally distributed fluid passages 120. The topper also includes an array ofsensors 122 capable of sensing a parameter useable for determining weight distribution of a person whose weight bears on the topper. One example is an array of pressure sensors. Ablower 72 is in fluid communication withtopper flowpath 60 by way of a plumbing network featuring amain feed pipe 124 and a set of branch pipes 126 each outfitted with a valve 130 and each connected to the foot end of one passage. The passages are coflowing passages, i.e. airflow in all the passages is in the same direction—from the foot end toward the head end. Acontroller 132 is in communication with the sensors, the valves and the blowers as indicated bycommunication pathways communication pathways blower 72 equally among the passages, the controller could be programmed to meter only 10% of the air to each ofpassages channels - The controller of
FIG. 20 is an on-board controller in that it is mounted on the bed itself. Alternatively the controller could be an off-board controller. Off-board controllers include controllers that are components of facility communication and data processing networks. - The foregoing describes topper embodiments in which the flowpath extends predominantly longitudinally through the topper. Alternatively (e.g.
FIG. 22 ) the flowpath can extend predominantly laterally through the topper. -
FIG. 22 shows a topper similar to that of FIGS. - 20-21 except with laterally extending, longitudinally distributed fluid passages 120. In general the passages are distributed across one of the directions (laterally as in
FIG. 20 or longitudinally as inFIG. 22 ) and extend in the other of the directions (longitudinally as inFIG. 20 or laterally as inFIG. 22 ). -
FIGS. 20 and 22 illustrate the use ofsensors 122 so that the topper, with the assistance ofcontroller 132 and valves 130, can adapt to changes in the position of the patient. Alternatively, the sensors can be dispensed with, and airflow can be distributed nonuniformly among the passages with appropriately designed, nonadjustable flow restrictions governing airflow through each branch pipe (e.g. as seen inFIG. 23 where the branchpipes feeding passages -
FIG. 23 shows a topper similar to that ofFIG. 22 but with counterflowing passages, i.e. air flows right to left inpassages FIG. 23 also illustrates the use of appropriate flow restriction to regulate airflow distribution among the passages. -
FIG. 24 shows a topper similar to that ofFIG. 23 but with a flowpath that increases in longitudinal dimension with increasing lateral distance from the inlets and outlets. The passages are coflowing passages. The illustrated topper does not use sensors, valves or flow restrictions to govern the distribution of airflow through the passages, however such use is within the scope of this disclosure. -
FIG. 25 shows a counterflowing variant of the topper ofFIG. 24 . -
FIGS. 26-27 show a topper in which aprincipal topper flowpath 60P has a keyhole shape as seen in a plan view. The principle flowpath has three nested, coflowingfluid passages secondary flowpath 60 S comprising passage 120A outboard of the primary flowpath. A nonflowing region could be used in lieu of the secondary flowpath. -
FIG. 28 shows a counterflowing variant of the topper ofFIGS. 26-27 . -
FIG. 29 shows a topper embodiment having a coflowing, keyhole shapedprincipal flowpath 60P with nested passages 120 whoseinlets 62 andoutlets 64 are at the side of the bed rather than at a longitudinal end of the bed. The region outside the flowpath is a nonflowing region. -
FIG. 30 shows a topper similar to that ofFIG. 29 but with counterflowing, laterally extending passages having a bulging workingregion 112 so that the passages, taken collectively, define a two-sided keyhole configuration. - Although this disclosure refers to specific embodiments, it will be understood by those skilled in the art that various changes in form and detail may be made without departing from the subject matter set forth in the accompanying claims.
