Benefits of technology

The invention is about a cover for a bed that has an opening that can be closed to prevent liquid from leaking into the bed. The cover is made of a special material that is designed to help reduce pressure on the patient's body, which can cause damage to tissue and lead to pressure ulcers. When the bed is raised, the cover moves to offload the pressure on the patient, which results in a shear strain that would otherwise occur internally in the patient's body. The cover is made of a monofilament fabric that curves towards the foot of the bed, which helps to compress it when a diagonally force is applied. This compression helps to counteract the shear strain and protect the patient from potential damage.

Problems solved by technology

This movement of the fabric, offsets a shear strain which would otherwise occur internally in the patient's body potentially damaging tissue integrity, which may contribute to pressure ulcers etc.

first embodiment

[0059]FIG. 6 shows a cross section through the mattress overlay according to the invention;

[0060]FIG. 7 shows a cross section through the first layer of spacer fabric in the mattress overlay according to FIGS. 4 to 6;

[0061]FIG. 8 shows a cross section through the first layer of spacer fabric shown in FIG. 7 with a load applied thereto;

[0062]FIG. 9 shows a cross section through the first layer of spacer shown in FIG. 8 with a load applied in a different direction;

second embodiment

[0063]FIG. 10 shows a cross section through a combined mattress and overlay according to the invention;

[0064]FIG. 11 shows schematically a cross section through the mattress overlay according to the second embodiment of the invention; and

[0065]FIG. 12 shows a plan view of the second layer of spacer fabric in the mattress overlay of FIGS. 10 and 11.

[0066]Referring to FIG. 4, a mattress overlay 1 is formed in a typical rectangular shape, with an upper surface 2, a lower surface 3, a head end 4, a foot end 5 and two long sides 6, 7. A strap 8 with an adjustment buckle 9 is connected to the head end 4 of the mattress overlay 1, to attach it to a mattress beneath. An inlet 10 is situated on the first side 6 of the mattress overlay 1 in the foot region. An outlet 11 is situated at the head of the mattress overlay 1 on the second side 7.

[0067]The mattress overlay 1 is suitably about 2′7½″×6′3″ (80 cm×190 cm) and about 2″ (about 5 cm) thick. The inlet 10 shown in more detail in FIG. 5 compr...

Abstract

A mattress or mattress overlay is provided, which is formed from several layers of spacer fabric. At least two layers of the spacer fabric are arranged such that the microfilaments in the layers curve in the same direction, towards the foot of the bed. Another layer can be provided, with layers which curve in the same, or a different direction, e.g. orthogonal. The top layer is more compressible than the bottom layer and the surface of the top layer of spacer fabric is provided with cuts in the heel region to reduce pressure at this high-risk bony prominence.

Description

TECHNICAL FIELD OF THE INVENTION[0001]The present invention relates to mattresses and mattress overlays including at least one layer of spacer fabric.BACKGROUND TO THE INVENTION[0002]Spacer fabric has already found use in mattresses and mattress overlays and US2011 / 0283459 proposes a mattress formed of a plurality of layers; a bottom layer of foam and an upper layer of spacer fabric. One example in US2011 / 0283459 proposes a plurality of layers of spacer fabric one on top of the other, in order to produce a greater overall height. In another embodiment of US2011 / 0283459 use of a ventilation device in the form of a pump / suction device is proposed to pump air into the upper (spacer) layer. Simple overlays formed of one layer of spacer fabric to be placed over a mattress are also known.[0003]Warp knitted spacer fabric has an inherent directionality in the monofilaments that separate the two textile faces due to the action of a knitting machine. As this stiff yarn is thrown from the need...
