Definitions

  • This invention relates to mattresses for sick patients prone to pressure sores.
  • Tissue damage can develop within a few hours if the patient either has inadequate changes of position or they have been lying on a mattress which does not re-distribute the patient's body weight over a wide skin contact area.
  • the consequences of a pressure sore developing can lead to a lengthy and expensive therapy regime, disregarding the pain and distress involved.
  • a mattress arrangement comprising:- an upper layer; and a lower layer; the lower layer comprising a plurality of discrete elongate portions extending longitudinally of the mattress arrangement, the elongate portions being detachably fastenable together; wherein one or more of the elongate portions is foldable upon itself.
  • each elongate portion can be folded up or coiled separately, meaning that the shape of the mattress arrangement as a whole can be manipulated across its width and length to suit requirements.
  • the lower layer comprises three elongate portions.
  • one or more of the elongate portions is configured to interlock with itself when folded upon itself.
  • the elongate portions With interlocking configurations, they will more effectively hold their folded or coiled position.
  • the lower layer and/or the upper layer is formed of laterally extending cells.
  • Such cells may be tubular and are cost effective to manufacture and offer effective support characteristics.
  • the elongate portions of the lower layer are detachably fastenable together by way of zips, buttons or velcro. These are suitable alternatives, although do not exclude the possibility of other fastening means.
  • the upper and/or lower layer are filled with soft resilient material, liquid, gas (e.g. air) or a combination of these.
  • the upper and/or lower layer are filled with air and are coupled to an alternating pressure source.
  • alternating pressure source with in particular the upper layer enhances the support characteristics of the mattress arrangement.
  • the lower layer has a non-slip coating to enhance the interlocking of elongate portions when folded.
  • the lower layer extends only partly along the full length of the upper layer.
  • the lower layer is provided in the region of the mattress arrangement intended to support the buttocks and legs of a patient.
  • the mattress arrangement is provided together with a support frame; the support frame comprising a patient support surface whose inclination can be varied and which is arranged to pivot in relation to a support frame base at a point at or adjacent the patient's buttocks region.
  • the mattress arrangement 1 of the present invention comprises an upper layer 2 which can be filled either with soft resilient material, liquid, gas (e.g. air), or a combination of these and can where appropriate be arranged to work with apparatus providing an alternating pattern of pressures.
  • an upper layer 2 which can be filled either with soft resilient material, liquid, gas (e.g. air), or a combination of these and can where appropriate be arranged to work with apparatus providing an alternating pattern of pressures.
  • this layer there are one or more lower layers 3 of soft resilient filling (such as foam chips), liquid, gas or a combination of these.
  • a lower layer 3 of soft resilient filling (such as foam chips), liquid, gas or a combination of these.
  • the lower layer or layers may extend fully or partly along the length of the mattress arrangement.
  • the lower layer may be attached to a base mattress 10.
  • One or more of the lower layers 3 can be divided into several equal or unequal elongate strips or portions 4 that extend in the longitudinal direction of the mattress arrangement. In the Figures three such portions are shown.
  • the separate portions 4 are capable of being held together with any suitable fastening means such as zips, buttons or Velcro.
  • portions 4 By undoing and fastening the portions 4 it is possible for some portions to lie flat and others to be folded or coiled. As shown in Figure 1 the nearest portion 4 has been so folded, the remaining two remaining flat.
  • the upper layer 2 is draped over this arrangement of humps and dips.
  • the upper layer can be attached to the lower layer with any suitable means.
  • a hump in the mattress arrangement that can prevent for example the knees of a patient flexing too far and the feet reaching the buttocks. It involves the patient lying on their back but with a mild tilt to their hips, they can either lie somewhat on their left or their right - according to which side the hump and dip have been created.
  • the lower layer 3 extends longitudinally from around the middle of the mattress arrangement down to the foot end and is attached to the upper layer 2 along a transverse line.
  • the fastening means e.g. zips closed and portions thus joined
  • the lower layer can be folded or coiled as one to provide a full width coiled lower layer that will stop the patient sliding down the bed when in the semi-recumbent position as shown in Figure 6. This is helpful in preventing shearing stress to patients' buttocks.
  • the lower layer 3 can be folded as one to provide full pressure relief to the feet as shown in Figure 5.
  • FIG. 6 there is shown use of the mattress arrangement together with a back rest frame support 14.
  • the support comprises a mechanism pivoting about hinge 15.
  • the support can be adjusted to different inclinations by way of the different stop positions 16.
  • the advantage of having the support hinge in the manner shown is that the support can be moved into position very close to the patient's buttock area. This is in contrast to conventional hospital beds where the back rest hinges from a fixed point on the bed frame adjacent the patient when seated upright. With such a conventional frame a nurse is required to move the patient backwards to be seated, which because of the difficult movement involved causes many injuries to nurses.
  • An additional application of this invention is to provide a flat side to the mattress arrangement onto which can be placed a mechanism that exercises a damaged knee.
  • a hump would serve to stop the patient who is sitting up in bed from slipping down the bed.
  • the present embodiment is also suitable for use in connection with the subject matter of UK Patent Application No. 9605722.9 and EPC Application No. 96935142.8.
  • means may be provided for assisting coiling and uncoiling of the elongate portions 4 as shown in Figures 7A and 7B.
  • a single elongate portion 4 is shown with straps 20 and 21.
  • Strap 20 is attached to the top of the portion 4 at position 22. It then passes around the front of the portion and then underneath the portion (shown in phantom lines) before passing around a pin 23 (acting like a pulley) and then returning underneath the portion to its front end. It will be understood that pulling on strap 20 in direction A will encourage the portion 4 to coil to the position shown in Figure 7B.
  • Strap 21 is attached to the front of the portion 4 at position 24 and is used for pulling out the portion in direction B from the coiled position of Figure 7B back to the flat position shown in Figure 7A.
