Description

Have mattress or the supporting pad that to expand cell

The present invention relates to a kind of as mattress, the supporting pad of mat is made of cell, it has by the bead of fluid institute blow-up or the shape of cell, interconnect or be not connected at base portion between them, to form the same entity of fluid space, fluid type is determined according to demand, fluid is contained in the different cells, the cell of arranging should make the unit intensity on its number or supporting pad surface few as much as possible, so that on the operating position, provide one to be suitable for the supporting pad object projection of wanting, uniform more supporting pad surface, have correct filling simultaneously.

This kind supporting pad can be used for the medical science aspect, mattress for example, and anti-decubitus pad and protection bedding and padding are particularly as back-lumbar support pad or be used to protect breakables.

This class supporting pad pad is known with regard to its principle, its principle be on the surface of its supporting pad, be adjacent to must supporting pad object because the equipressure effect of cell internal communication, no matter how the recessed degree in the supporting pad can provide same reaction; For example JAY is at US47266624, the mat of describing among US5018790 and the US5369829, one by fit together at grade several magnify the outer cover that the size thin plate constitutes and accommodate colloid be placed on the base than small scale, this cover comprises the compartment of vertical and horizontal, be interconnected between the compartment, so that hold isobaric liquid in the compartment that each on the base separates, this profile that covers on when in place presents the cylindrical shape air bag that vertical and horizontal are arranged with regard to this cover of analogy in conjunction with what the plane average height promoted to some extent, and its defective is to have the numerous tiny gauffer that blocks the skin blood circulation.

We know the bed of being described by HINSDALE in US945234, its mattress has the ballonet that is arranged to quincuncial circular cross-section, so that the top of these air bags becomes supporting pad portion and provide the most uniform pressure on the whole surface of the object of institute's supporting pad.Air bag carries out the static state inflation, the inflation that also can circulate, and be interconnected by the base portion of pipe network at them between them, form a single air chamber, so that the air pressure of being held is identical in all air bags.

In WO96/08185, Ouiger has described in the air mattress owing to having the pressure adjusting that the compensated chamber has.In EP 0651 659A1, Todter has described a kind of supporting pad of bellows type cell.In EP 0651 162A2, river strange (Kawasaki) described a kind of square cell supporting pad that each side of composition plane (upper and lower) can not be expanded that is positioned at, and supporting pad comprises the support lining bar that each row is intersected.Iskra has described the air cell supporting pad of the rule that can not expand on a kind of length direction in US5487197.In WO96/19997, Holdredge has described a kind of supporting pad that has turbine, and it mainly comprises the air bag that can not expand.Caldwell in WO93/2409, Johnson at WO94/19998 (US5373595) but and Evans a kind of control supporting pad with elongated inflation air chamber has been described in WO95/15706.

In EP0566507A1, Beaud has described a kind of supporting pad with the inflatable unit that is made of two thin plates, it is characterized in that on the connection plane of two thin plates an internal partition being arranged.In JP07000257, Yamamoto Giichi has described a kind of vehicle driver's of being used for cell shape cushion pad.In JP04030814 and JP0403813, Sagami Masaharu has described a kind of characteristics of inflation cell mattress.In JP03039105, Hiochi Toshimichi has described the adjusting of fluid in a kind of supporting pad (air or water).The defective of adjustable support or power assist apparatus is expensive, but can not abandon using supplemental support; The present invention can make supporting pad work under the power assist apparatus not having, and as those supporting pads of being mentioned, particularly by HINSDALE, GRAEBE BENGUIGUI or VIESTURS are described.Some medical supporting pad has our undesirable hammock effect in addition, and it has produced shear action and distributed bad for blood skin; For example for the Hinsdale mattress, under the situation of anti-decubitus, this harmful effect will be replaced by the canvas above the cancellation or with the extraordinary silk of ductility of " jersey " type and is eliminated.Patent GB1341325 has described the essentially identical mattress of a kind of principle, and it is inflated by a turbine, and DOUGLAS also describes in US4279044 to some extent.

In JP05084123, Ichida Michiyasu has described a kind of regulating system in truncated cone shape cell mattress.

GRAEBE has described improved this class supporting pad in US3605145, it is made of air bag or conical cell, and it installs the cell base portion that forms at two thin plates channel connection.Next GRAEBE has described cell then, and its cross section becomes star, and cyst wall can be expanded the volume that does not fill fluid to occupy.We can also become these air bags or cell on the vertical or horizontal pedestal that is arranged in them, make them have uniform supporting pad surface in filling or after heaving, this will not be the situation that has air bag described in US945234 of HINSDALE for example, arrange if they are aligned to identical vertical and horizontal.GRAEBE discloses the invention of cell expansion at patent US3870450 and US40005236 respectively at 1975 and 1977, the manufacturing mould of a supporting pad has wherein been described, the principle of this supporting pad is identical with aforementioned patent US's 3605145, the characteristics of its principle are based on the expansion of cell and are communicated with on the passage that the installation of two thin plates forms by pedestal between them, its forms one and goes up the lower plane in plane, and this is identical with the mat described among the U.S. design patent D355558 fully.Can be when leaving unused the cell of unaerated be included in one and have or do not have in virtual cover pin, the uniform from top to bottom or uneven circle of cell, square, square-section, what for example EVANS disclosed in US4864671 is such, and the fluid that charges into can be different.The connected system that has fluid between cell is described in US4422194 as VIESTURS, and single support has the square-section, can be made of the thin plate that is positioned at the joint face both sides each other.SEBAG and BENGUIGUI have described another kind of have four branches of parallel sides or the cell of the wing in US5553220 (EP0721755A1), the adjacent cells side be recessed to form the surface, they have adopted the distribution grid of FR2707873 basically.

ROUSCHAL has described cell in DE-U-9410601, but main describe pass through to glued joint between the cell, at the connected system of upper thin sheet and the formation of lower thin sheet interplanar, but only round the periphery of supporting pad.

GRAEBE has also described a kind of simple little chamber shape in US45441136, it only has four branches, and as the leather football bladders of half unaerated, its cross section becomes cross; The star font of GRAEBE or four cross branches stop at four corner places.In the prior art, two dividing plates of plug or opposed edges surface, radial rib) and US4541136 (claim 2: the sidewall of a pair of low coverage separation) two dividing plates that cell is relative or edge surface also are adjacent and parallel thus: us4005236 (the 3rd row, the 13rd row:.EVANS claims that in US4864671 this wing is " ridge ", and has used term " pleat " for the sidewall of cell, and GRAEBE has used " falling recessed sidewall " in US4541136.In addition, in US4005603 and US5052068, Graebe has described the shape of different cross section cell in a large number, more or less wing shape is not described on the quantity of its related cell, as described in the front, retouch be among the US4005236 they radial layout and US4541136 in two parallel baffles.Our difference and the advantage that will see in specification of the present invention for example, the wing shape of the existing technology that this also can be by will there being two surfaces and the comparison of the wing shape of the present invention show.This simple shape, the various mechanical properties of the cell of describing in front except GRAEBE with a plurality of branches or wing, by the cast between two moulds, basically can simplify required plug and the composition surface between two moulds of manufacturing cell is on the cell longitudinal axis, the pouring procedure of two moulds can be used for all products except that aluminium, each is metal die preferably, pour into a mould the wing of a complete branch or plug and a sidewall of adjacent two branches, as described in US5553220 for the cell, in the case, the composition surface of two moulds is not a plane but becomes " Z " shape, therefore avoided the aluminum plug is carried out sand casting, this is necessary during for the production of supporting pads such as for example mat.This star glyph shape plug that to be unique permission have a down dip with the single-piece of two die castings with four branches, rather than four, in fact for a cell, three moulds must be arranged, and five moulds just must be arranged for the cell of five branches with three branches; The sand casting of aluminum plug is not too expensive, but surface state is coarse; Some lost wax casting is extraordinary, but expensive; Processing cell plug is an expensive problem.Casting a complete cell plug comprises: the top, and body, the bottom can create in the mould of the flexible resilient of a single-piece; We also can push the manufacturing body, install top and bottom then.The connection of the cell between described in the specification they is known.Based on same equal pressure principle, GRAEBE has applied for patent US4698864, International Application No. WO 94/10881, patent US5163196 and patent US5502855.GRAEBE has described the pyramid cell that can not expand in US5369828 and US5551107 and US5561875, and a kind of cell mat that has the moulding base portion has been described in WO93/16622, cell obtains by thermoforming in WO96/12426, and also has the base portion of a mold pressing in WO96/14004.Originally Graebe has described a kind of square cell supporting pad in US5152023.In the design identical with JAY, Graebe had once described three patents in his numerous patent, described the mat with the cell that communicates with each other in US4953913, the application PCT/US/9310626 (water-filling foam base) that is published on May 26th, 1994 and D342411 and D367199.EVANS has described the tree-like cell expanded on Christmas in US4864671, as same square accordion.In WO96/33686, bosshard has described a kind of support with band topping up cell, and inspection pressure safety device is equipped with in this support.The another kind that discloses a period of time supports in the series " antidecubito " by commercialization called after " DOMINO " at it based on the mat of the known equal pressure principle CHINESPORT by Italian UDINE, its cell is to be made of four cylinders, its top is hemispheric, its end is higher than the cell that supporting pad face and vertical four four ground are joined together to form a non-expansion, and it has avoided motion sickness by the lateral movement of restriction cell according to data.

In the application PCT/DK93/00069 that is published on September 2nd, 1993, RASMUSSEN has described a kind of plant fiber packaging device, as if it has not too expensive advantage, but can not reuse.In WO93/00845, COLVIN has described a kind of buffering combination mat, it by brachymemma or polygon air cell constitute, be can be reusable.

In US5243722, GUSAKOV has described the sub-assembly that a kind of fluid fills the cell that rises, and it connects the plane with respect to the centre is symmetrical.

These different supporting pads have following major defect respectively: or cell can not expand to it not during blow-up outside the occupied space, and this needs quincuncial layout; Perhaps to stay the vertical or horizontal alignment that free space is used for cell, these cells can not be expanded, or in the supporting pad of GRAEBE, expansion is subjected to the restriction of cell periphery, expansion also is subjected to bigger restriction at the angle place of the cell with four branches, and four branches end at four corners; Or description is difficult to the relative complexity of the cell of definition.

At last, each cell in the supporting pad cell that ROUX has described in french patent application 95/08972 communicates with each other, its major defect is to determine the cell of multiple wing not at all, particularly undersized cell, cross section up to three or four centimetres, like this, be difficult to consider all that in describing in front, for example the acute angle of being mentioned in this manual is in addition slick and sly to satisfy actual needs.Principle of the present invention in addition has its advantage and difference with respect to the cell of cell with parallel baffle wing and unusual shape, these unusual shape Graebe do not define in US4005236 and US5052068, and we will quote this two pieces of articles in the following description.

It is also noted that Graebe has described the shape of unusual multiple wing cell in US4005236 and US5052068, these shapes are definition not, and particularly all it doesn't matter with its invention of describing in US4541136 and US5052068; Roux has described in its application that all other are dissimilar among the Fr95/08972, but compared with prior art, can not determine that at all this invention has unanswerable advantage and difference.

The invention provides the solution that can overcome the art methods defective.

Therefore the object of the present invention is to provide medical bed mattress, mat, bedding and padding, the reusable packing of friable product, supporting construction with the buffering that can expand cell, this cell mainly is made up of following: upper thin sheet, generally be soft, has definite shape, it comprises extendible cell, can expand internal communication or be not communicated with when they are full of liquid, a cell is imaginary by at least two parts in the body cross section of idle state, concentric inside and outside periphery carries out the part qualification arbitrarily, difformity has: square, and pentagon, octagon, circle, irregular shape; Here, seam, fracture or breach mainly comprise dividing plate; Basically adjacent more or less, parallel or not parallel, have gradient or back draught, straight line or recessed, protruding or folding; Outer periphery is connected to interior periphery mainly to be suitable for for example broken line, be used for four limits are connected to the middle section of capsule or cell, this has certain advantage, the partition part that it is characterized in that cell can become straight line under certain conditions fully, and this its tie point of cell partition part is positioned on of different peripheries.

Other characteristics of the present invention and advantage will be below specification and accompanying drawing in describe, the accompanying drawing that does not limit any feature illustrates as embodiment.For more for simplicity we will see, the single line in the profile is the constituent material of cell; For ease of considering the description of known technology, the space that these lines limited and held can be corresponding to plug or formpiston, and the zone outside the single line of figure limits can be corresponding to former.The dot of the dotted line and the expression longitudinal axis is not represented any material, but is used to illustrate the cell body, the scope of a part of imaginary outer cover is described, or is used to locate cell with respect to its longitudinal axis.When describe be the idle state of cell the time, this just we can say it be in a position and when it in the shape that is had on die location the time before the demoulding; Therefore cell can be in idle state when supporting pad is assembled; The idle cell that assembles supporting pad is counted as being equipped with liquid, and its volume equals to be used for the volume that it makes the positive plug of cell, and is not to be in the exterior mechanical constraint, under the situation that is subjected to atmospheric pressure.

The purpose of this invention is to provide medical bed mattress, mat, bedding and padding, and the reusable of friable product is packed, and has the design of the buffering supporting pad that can expand cell.

A kind of supporting pad or bedding and padding mainly are made up of following: upper thin sheet 1, generally be soft, has definite shape, it comprises extendible cell 3, inside is communicated with when they are full of liquid, can expand, for example a cell is by at least two imaginary peripheries in the body cross section of idle state, inner rim 6 and neighboring 7 limit, described two peripheries be concentric and in be connected on the difform air bag, difformity has: square 16, pentagon 19, octagon 17, circle 18, irregular shape 15 and 20; Here, seam, fracture or breach have comprised dividing plate 4 substantially; Basically adjacent more or less, parallel or not parallel, have gradient 8 or back draught 9, straight line 21 or recessed 10, the 12a and the 12b of protruding 11 or folding; Outer periphery 7 is connected to interior periphery 6 (main dotted line 14, but be not limited thereto, only be example) herein, be used for periphery 7 point 22 be connected to more or less near capsule or cell (Fig. 3// Fig. 2// Fig. 1// Fig. 4 a Figure 12) the point 23 of middle section 6 of axle 24, this has certain advantage, the partition part that it is characterized in that cell is in and can becomes straight line fully on the track entad, this cell is connected on two points, its each point is positioned on the periphery 6 or 7, if at other of the inlet of seam continuous on the neighboring 7 or breach 4 or distally outlet or opening between 2: 28, ensuing track at least strictly piggybacking on a segment length of straight line or tabular surface 29; Back one of 2: 28 be positioned at being connected of seam, on the neighboring of outlet or opening first identical; The point on 29 is not far away than other to constitute all point symmetries of this tabular surface 29 or asymmetric axle center 24, by the symmetrical plane of chamber center 24, outside tabular surface 29, each stitch continuously 4 junctions 2: 28 between track on constitute and cover 7.Can see that (Fig. 1) has the upper thin sheet 1 of definite shape, it is made of the inflation cell; The benefit that cell is linked together one by one by thin plate 1 is can obtain various benefits in manufacture process, thin plate 1 fits together (Figure 18) with thin plate 2, although may assemble the independently cell from one of thin plate 1 independent cell or one group of internal communication on thin plate 2, the remainder of this and supporting pad is irrelevant.

The periphery of inflation cell equals to cover with one heart lip-deep visual outer length and adds and these concentric inside length sums of covering the number of repetition of the seam that links to each other.The shape of cell, for example described in the present invention, have the characteristics different with the prior art cell, and it comprises linear branch, and (Fig. 4 a), cell of the present invention has dividing plate, and has the wide surface (Figure 15 b) of go up extending, and it seems and resembles seam, fracture or breach, and in the depression that has under the improved situation of parallel baffle cell (Fig. 4 b).As what describe in the prior art, cell 3 (Fig. 1 and Figure 18) comprises on the longitudinal axis 24 length from high to low: the top 25 of cheese or dome shape, promptly when cell charges into fluid, and be in when idle when cell, again in conjunction with the central point on this top, this point preferably is positioned on the longitudinal axis dividing plate on the outer cup at leisure; Body 26 of the present invention; The inessential base portion 27 of shape, it is the same or different when idle with body, more or less has bigger size on height and length.The bottom of seam and be in that the recess of cell when idle is general to be combined in thin plate 1 and 2 be connected on the cover plate 7 on the plane gradually again is the expansion that can be convenient to be sewn on this scope equally.

Seam preferably has a more or less adjacent parallel or substantially parallel dividing plate 4, and is recessed 10, projection 11, and gauffer 12a and 12b: the dividing plate of seam not necessarily must be with respect to the sagittal plane symmetry (Fig. 3) of seam, also not necessarily must radial (Figure 19).The wing of cell or branch are comprised and are defined between two adjacent and continuous or recessed seams that the wing preferably generally has triangle at least, but also can be that four limits (Fig. 5) (Fig. 4 b) or other have the shape of inner vertex.

By with the comparison of the product of prior art, wherein first (Fig. 2) is described as a star that is formed by eight branches 5, they are connected to imaginary central authorities part 6 in addition, and be accommodated in the outer cover 7, second (Fig. 4 is a) as the same star that four branches are arranged, they end at four ends of square outer cover, can see that from branch's distal end to portions of proximal, the dividing plate of branch 5 is linears 13.By relatively the present invention, its advantage is to replace dividing plate (Fig. 2 of these straight lines; Fig. 4 a; Figure 12), straight line is to the shortest distance of another point from a bit, flat by 29 (Fig. 4 b) or the dividing plate by longer cell, for example putting between 22 and 23 in the mode of dotted line 14, each point is positioned on concentric peripheral 7 and 6, the partition part of cell is followed the track of outer cover and display (Figure 17 in their distally track in its entad track, 14,11,9,3), track at least flat 29 2: 28 between on the part of outer cup (Fig. 4 b), the flat of most preferred embodiment has and is about between 2: 28, in outer cover 7 and distal end portion or two air line distance 1/4th to 3/4ths between the opening of seam 4 continuously, and at the opening between their the far-end dividing plate that the is called as partition part two adjacent parts or stitch among the 4 near-end tracks, seam 4 is adjacent substantially more or less with dividing plate, here, be called as adjacent tracks center 24 near, in the track of these dotted lines 14, be radial; The sagittal plane of seam be with seam relative dividing plate between the mid point plane, will see a little while that as us this plane needs not be radially usually.Can see, according to the present invention, when a cell has the cross section that 4 seams (Fig. 5) are arranged on the side, its periphery of fluid-filled cell increases from 3% to 25% in fact apparently, be increased to 40% in theory, we will display in the back, and (Fig. 4 a) has a plurality of to the wing that it has with respect to the criss-cross cell with two sides wing, as the star (Fig. 2) of same eight branches, its periphery that has is less than the inner rim (Fig. 3) of the cell that has eight seams.The effect of the pentagon (Figure 13) of star of quintafurcation (Figure 12) and five seams is identical.Yet as mentioned above, the cell of eight branches (Fig. 2), (Fig. 4 a) has a wing of parallel diaphragm plate to the cell of cell of quintafurcation (Figure 12) and four branches.According to the present invention, if the principle of flat 29 is applied to can reduce periphery as shown on the 3rd face of outer cover 7 scopes on Fig. 4.In theory, consider figure (20) and (21), in having demonstrated, it is connected on the cross section of the cell body in the square cover of same size, it is respectively the extreme case of example shown in figure (4a) and (5), here the wing is tiny as much as possible and seam is narrow as much as possible: " d " is square half cornerwise length here: satisfy at cell under the criterion situation of figure (20), the cell periphery equals 8 times " d ", cell satisfies under the criterion situation of figure (21), periphery will equal " d " 16 times, be equivalent to the square root divided by 2.If 2 square root equals 7/5ths apparently, the theoretical periphery (Figure 21) of cell will approach ten half as much agains of " d ".Therefore the theoretical periphery of the cell of figure (21) is approximately greater than 40% of figure (20) cell periphery, (Fig. 4 a) compares with cell of the present invention (Figure 15 b), and the increase part of the length of invention is poor between outside length (Figure 15 b and 4a) and prior art (Fig. 4 b and the 4a) wing thickness on obviously with the wing of prior art or branch more simply.By 2: 28 add one for example defined (Fig. 4 b) tabular surface in front (29) to make advantage of the present invention theoretically be irrefragable, even less.For example it is applied on the cell with parallel baffle that Graebe describes in US4541136.

At first Graebe is in its former parts of patents, and then at patent US4541136, and then Benguigui has described a kind of cell in US5553220, has at cell under the situation of four branches, and its wing has parallel dividing plate, particularly also has lateral concave; No matter be for Graebe or for Benguigui, a symmetry axis and at least two symmetrical planes are all arranged, US4541136 (Fig. 4 a) in the cell of description have four symmetrical planes.In all cases, the wing of parallel baffle can be derived recess, recess has parallel baffle never, in patent application Fr95/08972, all stitch for cell, the layout of the wing and seam can make that the dividing plate of same seam is parallel, in addition according to the present invention, cell can have the wing of all parallel baffles, and each wing is around the cell with parallel baffle, for example all wings of cell, if they are positioned to as two back-to-back combs, the tooth of comb is exactly the wing, and then these wings can be parallel baffles just, and are looped around around the seam of parallel baffle.Although comprise very multiple wing at cell, perhaps its sectional dimension is little of being about under 10 to 40 millimeters the situation, actual cause for bedding and padding or supporting pad validity, crude angle in the soft thin plate 1 of cancellation cell 3 and the longitudinal rib that brings, having one two to five millimeters radius of curvature, is that the protruding especially all crude angle actual needs in neighboring 7 of one millimeter sweep make its slyness sometimes.According to the constituent material of manufacture method and cell, clear and definite difference of the present invention and advantage.According to the present invention, on the neighboring 7 adjacent two the seam 42: 28 between included space must comprise a tabular surface 29 (Fig. 4 b) (Fig. 3,5,6,7,8,9,10,11,12,13,14,15,16,17,19,21).As an example, we regard tabular surface 29 as tangent line or string among the figure (4b), bring any problem for scope of the present invention with respect to the foreign range between 2: 28 of prior art, no matter because be that what shape cell can be, we only consider the actual size that it is initial, that is to say the size and the volume of cell when being in idle state, obviously, for all sizes of the given cell of prior art and for all sizes of the present invention, according to the present invention, the volume that is held when cell is in idle state is very important, and the periphery of cell is very big, according to the present invention, two on the track of outer cover 7 continuously the institute of the formation tabular surface 29 between seam 4 junctions 2: 28 a bit put more away from center 24 than all of the cover 7 that between point 28, does not constitute straight line or tabular surface 29.

Enforcement of the present invention can be seen, in the time of outside cell expands to its rest position, therefore the increase owing to the cell periphery makes cell reducing in supporting pad per surface upper density, kept best validity, its result is as having obtained material, the advantage of energy, for example for drying, polymerization, sulfuration, usually will be for the drying of the upper thin sheet that is obtained by good ventilation, and by for example with in plug or the formpiston soak-out material bathing pool: comprise latex, polyvinyl chloride or other, this will make its equably coated in male mold surfaces, the cell of particularly working as supporting pad, when for example mattress has 10 to 40 centimetres height, this can obtain very big benefit, therefore: for the manufacturing time of upper thin sheet, all these advantages for normal conditions, also have installation in addition for the upper thin sheet of moulding, and for the lower thin sheet for the acquisition final products, because need be very big by the surface area that the plane connects, therefore the invention enables adjacent two row cells to have bigger space, so the desirable thin plate 1 and 2 of installing is these bedding and padding or supporting pad can only be installed on the periphery of bedding and padding or supporting pad.According to a most preferred embodiment, as shown in figure 18: the supporting pad that has a upper thin sheet 1 to constitute, be mounted with cell 3 and a lower thin sheet 2 above it, smooth base portion (Fig. 1) or become definite shape (Figure 18) base portion (it can be placed in on for example Polyurethane foam base of semihard of definite shape equally) to be made of the assembling of thin plate 1 and 2: we also can be as realize supporting pad under some situation of prior art, it is to be made of two shaping sheets 1, first is still as top (Fig. 1), and second is turned, make the top 25 of these cells become upside down and pin 27 up, all these is with respect to connecting plane symmetry; According to supporting pad, people can also cancel the cell of shaping sheet 1, so that combine for leaving space between the remaining cell or with any other cell height.Connected system between the cell is different, and be known in the art.

According to most preferred embodiment, all protrude into cell acute angle and protruding into the thus acute angle that is used to make the shaping dies of cell will be removed or make as previously mentioned slick and sly.

The seam dividing plate preferably can be, parallel-plate 4 has gradient 8, has back draught 9, dividing plate all is to become straight line 21, and spill 10, convex 11 perhaps can also be broken line 12a and 12b.Being sewn at least two distributions between the concentric periphery can be at random: that is to say that a seam with broken line shape dividing plate can be adjacent with the seam with parallel baffle.

According to most preferred embodiment, the cover category of the outer phantom except the shape of irregular section preferably has a square-section 16, circular cross-section 18, and pentagonal section 19, octagonal cross-section 17, and decide according to the current intelligence of product in the reality.

The quantity of seam is by the width of inner concentric peripheral extent, limited at the thickness of the cell constituent material of the length of the thickness of this scope wing and inner concentric periphery and applied mechanical quality and characteristic.And the quantity of seam is many more, can satisfy the purpose that reduces cell density on the supporting pad per surface more, however, for the problem of the manufacturing of medical supporting pad or bedding and padding and enforcement we can limiting slit quantity, we will be described later.Under extreme case, if cell has very many wings, the difference between prior art and the invention is described below.

According to the present invention, be used to make the signal shape of the plug wing of cell, by for example immersion liquid processing, and this wing that is in the idle state cell is the part that is included between the two continuous or adjacent seams, it be usually expressed as triangle (Fig. 3) (Fig. 6) (Fig. 7) (Fig. 9) (Figure 10) (Figure 11) (Figure 15 is (Figure 17) a), quadrangle (Fig. 4 b) (Fig. 5) or identical substantially with triangle at least shape, its summit is positioned at the sidepiece of inner cover, its bottom is positioned at the sidepiece of outer cover.According to the present invention, we can say that the wing of the cell of idle state comprises three faces, each of its two sides comes from the two continuous dividing plates of seam at least, and at least then track of outer cover of face, the 3rd face comprises that at least one is along outer cover 7 track tabular surfaces 29.

Cell expansion in corner on diagonal of satisfying figure (6), (7), (9), (10), (11) description is more effective, avoided the defective of the supporting pad of cross arrangement between cell, therefore a supporting pad surface more uniformly is provided: these arrange assembling (glueing joint welding or other modes) zone corresponding to upper thin sheet 1 and lower thin sheet 2.

For the outer phantom perimeter 7 of anti-decubitus supporting pad can have an appointment 2 to 20 millimeters interval of the cross section of 10 to 100 millimeter, the dividing plate of seam can be arranged, the thickness of cell dividing plate can change from about 0.5 millimeter to 2 millimeters.Can allow 4,8 for anti-decubitus supporting pad or bedding and padding, about 10 even number seam, center longitudinal axis 24 can be a symmetry axis.Can allow the odd number between at least 3 to 9 to stitch for anti-decubitus supporting pad or bedding and padding, possible symmetrical plane passes through central shaft.Be noted that to making the best results of supporting pad, in cell, not necessarily need symmetry.

Be appreciated that the present invention can be used for the cell of different shape, remember mainly that wherein those examples, cell are included in two pars 29 of seam between 4, the therefore minimum seam 4 that comprises with par 29 as much:
