Description
(54) A MATTRESS OR PAD TO SUPPORT THE HUMAN
BODY
(71) I, RONALD JAMES PEWTER EVANS, of British Nationality, of 11 Florida Close,
Bushey Heath, Hertfordshire, England, do hereby declare the invention for which I pray that a Patent may be granted to me and the method by which it is to be performed, to be described in and by the following statement: In the past, resilient cellular resin sheets and blocks have been used to form cushions and mattresses, but such equipment is unsatisfactory for use by invalids or patients who must lie on the same for long periods of time. This unsatisfactory condition arises from the fact that the contacting surfaces of the resilient material are subjected to shear pressure when contacted by curved and flat portions of the patient's body and, as a result, the resilient material does not provide controlled support for the patient.
Furthermore, due to the curved configuration of the patient's body, certain portions of resilient cushions and mattresses that have been used in the past become compressed to a greater degree than the balance thereof, whereby the supporting resilient cushion or mattress does not exert a controlled pressure contact on a patient lying or resting thereon.
It is a first object of the present invention to provide a pad of resilient material, preferably a cellular resin material, in which zones thereof are provided with different characteristics of compression resistance such that, when the pad is in full pressure contact with the portions of the patient resting thereon, the peaks and valley portions of the body in contact with the resilient structure are subjected to substantially uniform pressure where required.
A second object of the present invention is to provide an article for use as a bed pad, mattress or seat cushion in which there are removable and replaceable portions of resilient material, preferably a cellular resin material, which can thereby be selected with characteristics of resilient support suh that there is full pressure contact with the portions of the person's body resting thereon, with the peaks and valley portions of the human body being subjected to substantially uniform pressure where required.
According to the present invention there is provided a mattress or pad for use in supporting the human body, comprising an elongate support consisting of one or more slab-like members made of resiliently compressible material and which includes, when viewed on a major face, at least two zones intended to support respective different portions of the human body, wherein the material of the elongate support in one of the zones has formed therein towards one end of the support member a plurality of elongate divisions disposed parallel to each other and parallel to the length of the elongate support, said one zone having a compression resistance of one value, and wherein the material of the other zone towards the other end is formed therein with a plurality of individual cutaway regions or divisions arranged in an array whereby a plurality of supporting sites occur, said other zone having a compression resistance of a different value to that of said one zone.
The divisions and/or cut-outs in the elongate support which pass partially through the material from one major face of the elongate support towards the other major face thereof, or which pass completely through the material from one major face of the elongate support to the other major face thereof, and the cuts may be arranged so as to define island sites in the material at least at one major face of the slab-like member. By way of example, the cuts are arranged in two sets of interrupted parallel lines at right angles, or in continuous parallel lines.In an advantageous form, the width of the cuts is made such that each portion of the material bounding a cut may be laterally distorted, within limits, when subjected to compression, without thereby engaging frictionally with the other portion of material bounding the cut sufficiently to prevent the compressed material from re-assuming its unconstrained shape when the compressing force is removed.
By parting the material of the layer, at and adjacent to that major face which is presented towards the human body, there is obtained an effect of division of the body of the material into sites which are unconnected to, or are only partially connected to, adjacent sites, to the extent that when a load is applied it becomes supported by each site acting substantially independently of other sites, without for example any lateral dragging of the upper or outer skin layer of the material.
The extent of the removal of the cutouts governs the weakening of the sites in a zone.
By way of example, a pad suitable for supporting essentially two parts of the human body, i.e. a first part capable of withstanding relatively heavy surface loading, and a second part capable of withstanding only a lesser surface loading, could compromise a first zone having portions cut away along a single set of lines, e.g. parallel lines, and a second zone having portions cut away at intervals along two sets of lines at right angles to form cut-outs having cruciform sections, whereby the first zone has a relatively higher compression resistance than the second zone.
The material used for the layer is advantageously a svnthetic resin foam such as polyurethane. This can be cut and cut away with well known techniques utilising heated blades and wires, but the method is laborious and time-consuming where large areas must be treated. In accordance with a further feature of the invention, the pad is composed of a sheet or block of foam material in which the cut away portions are removed by die cutting of the sheet or block normal to its major faces. In order to strengthen the elongate support, it may have a flexible backing sheet, laver or block of the same or any other suitable material secured over that major face remote from the patient's body. Where the sites are totallv separated discrete island sites. they may be retained in position relatively one to the other by being secured to the backing sheet or block.
According to a still further feature of the invention, the layer may be a sheet or block which is moulded or manufactured with the partially separated sites already defined therein.
Iil a preferred arrangement, all or part of the edge of each site adjacent to the face presented towards the patient is radiussed or chamfered, particularly for the purpose of lessening risk of interference of one site with another when under compression.
According to a further feature of the invention, the elongate support is composed of two or more separable portions each corresponding to a zone, and there is provided a retainer serving to retain said portions in assembly. The retainer may include a peripheral rim element surrounding the elongate support, and preferably said rim element is made of a resiliently compressible material. Advantageously, the peripheral rim element has a compression resistance which is greater than the compression resistance of the material of any zone of the elongate support, so as to tend to prevent a patient rolling off sideways.
The retainer may include a flange extending inwardly from the peripheral rim element, or a rigid base.
In order that the nature of the invention may be readily ascertained, some embodiments of pad or mattress in accordance therewith are hereinafter particularly described with reference to the accompanying drawings, wherein: Fig. 1 is a perspective view of a first embodiment of pad or mattress;
Fig. 2 is a perspective view of second embodiment of bed pad or mattress;
Fig. 3 is a plan view of the embodiment of Fig. 2;
Fig. 4 shows some undercut formations and a parallel cut;
Fig. 5 shows, to a larger scale, some further variations of cut.
Referring to Fig. 1, the pad or mattress comprises a sheet or block 1 in which there are two zones, respectively 2 and 3, in which material is absent in different manners. In zone 2, the material is absent, completely through the sheet or block, along a series of parallel elongated slot areas 4, thereby to define a series of elongated parallel sites 5. In zone 3, the matenal is absent completely through the sheet or block, at intervals along two sets of parallel lines disposed at right angles, thereby to define a plurality of island sites 6 each joined to adjacent sites or to the remainder of the sheet or block by relatively narrow necks 7.
The sheet or block 1 may be made by die-cutting of a full sheet or block, or by moulding or manufacturing it in the form shown.
The shaped sheet or pad is secured, at its other major face, remote from the patient's body, to a full sheet or pad 8.
The edges of the sites 5 and 6 could advantageously be radiussed or chamfered at the upper major face.
The zone 9, between zones 2 and 3, again has a different compression resistance from that of the other zones, by virtue of not having any cut portions at all.
Referring to Figs. 2 and 3, the pad or mattress comprises a retainer having a peripheral wall 10. The retainer wall is made of a relatively stiff resilient resin foam and defines a rectangular enclosed area within which are assembled support elements 12, 13 and 14. The underside of the retainer, not shown, may be a layer of the same resilient material or a simple flexible backing sheet of plastics or fabric.
The element 12 has a set of lines of division 12a which extend parallel to each other in a single direction. The element 13 has no lines of division, and the element 14 has two sets of lines of division 14a and 14b running at right angles. If the three elements 12, 13 and 14 are made of the same resilient material, the element 13 becomes the "hardest" i.e. will provide the most support per unit area, and the element 14 becomes the "softest". The characteristic of element 12 would be intermediate those of elements 13 and 14. The pad is dimensioned such that the respective elements may carry different parts of the body, varying as to whether they constitute downward projections, e.g. the back of the head, the shoulder blades, the buttocks, calf muscles, or heels, or "valleys" e.g., the neck, the waistline, the thigh, or the ankle bone.For example, the head could be positioned at line C-C, and the lower leg at B-B, the middle of the body being on element 13.
Fig. 5 shows some representative undercut cross-sections for lines of division in the elements, e.g. as at 20, 21 and 23, and a simple parallel-walled cut as at 22.
Fig. 4 shows a plurality of different division formations in a single block, e.g.
simple narrow and broad parallel-sided cuts shown respectively at 25a and 25b, and chamfering as at 26, or a broad V-shaped cut as at 28, or a simple cut as at 29 with one edge surface more chamfered than the other.
It is preferable if the chamfering 26 of all of the cuts is such that if one of the portions of the layer is compressed it will not frictionally engage with the adjacent section. when released. The depth of the cuts 25 may be varied to vary the spring constant of the material. The intermediate zone 27 may be made thicker or thinner, depending upon where the cuts have been made, and the required spring constant of the material reduced accordingly. The shapes of the various cuts 28, 29, 30, 21, 22 and 23 also provide varied spring constants for the material.
A commercially available high resilience polyurethane foam which has been found suitable for carrying out the invention has the following characteristics:
Density: 30-60 kilograms per cubic metre
Hardness (BS 3667) 14-17 kilograms at 40%
compression
(BS 4443) 95-115 Newtons
Tensile strength: 10 Ibs. per square inch.
Elongation: 150%
Compression set: 10%
Rebound resilience: 60%
