Decubitus pad

Honor

The invention relates to a bed pad for preventing bedsores in bedridden patients, in particular for hospital beds. The requirements for bed pad mats of this type are to create conditions for bedridden patients that prevent bedsores or, for example, contribute to the healing of existing bedsores or burns on the body. To achieve this, high moisture absorption and good ventilation must be ensured, two conditions that seem to contradict each other in terms of the product.

Based on this, the present invention is based on the object of creating a bed pad of the above-mentioned type, which ensures dry and well-ventilated lying conditions for the bedridden person with a high moisture absorption capacity and is washable in a way that guarantees hygienically perfect conditions with multiple reuse.

The solution is a bed pad that is characterized by the following structure:

an upper cushioning layer comprises at least one spacer fabric, where the upper layer consists of multifilament threads and all pile threads are formed by monofilament threads, a lower absorbent layer consists of a nonwoven mat with a high proportion of viscose fibers, which is coated on the outside with a waterproof web. The unit consisting of the outer layer and cushioning layer and the absorbent layer can be separated and reconnected without causing any damage. In particular, it is intended that

that the upper cushioning layer consists of two components: an upper outer layer is formed by a first spacer fabric, the upper layer of which consists of multifilament threads and the pile threads are made of monofilament threads, a middle cushioning layer is formed by a second spacer fabric, the outer layers and pile threads of which consist of monofilament threads, the upper outer layer and the cushioning layer are permanently connected to one another.

This structure covers the complex requirements of the product in an extremely favourable manner, whereby the effect of the individual components can be explained as follows. The first spacer fabric is skin-friendly due to the use of multifilament threads and creates favourable conditions for direct body contact through the structuring into individual pads or ribs with gaps between them for air to enter. By using less heavy and therefore less stiff threads, a pleasant soft touch feeling is created.

The second spacer fabric, which is preferably produced using stronger threads, creates the necessary flexibility for padding on a larger scale. The use of synthetic fibers, in particular polyester fibers, ensures that the layers that come into contact with the skin surface do not absorb moisture, but instead pass it directly down into the fleece layer. At the same time, this ensures that the skin is ventilated due to the permeable structure of the spacer fabric. If the two spacer fabrics are connected to one another on a larger scale by quilting seams, an overarching structure is created that again provides improved air access and may have a blood circulation-promoting effect.

The moisture-absorbing fleece mat is only placed underneath the two layers of spacer fabric, and its material and dimensions can be adapted to the preferred application. If normal conditions prevail in which only body sweat needs to be absorbed, the mat can be made thinner for reasons of cost and weight and to make it easier to wash. If there is also wound fluid in the case of existing bedsores or burns, or if elderly patients are also incontinent, the fleece mat can be made thicker. The lining of the fleece mat on the lower outside prevents the absorbed fluid from penetrating the mattress. The mat must of course be changed regularly.

The separability and reconnectability according to the invention of the upper unit made of spacer fabric and the lower unit made of fleece mat and sealing layer has the advantage, with regard to what has just been described, that a uniform type of the first unit can be combined with different fleece mats as required. This is primarily intended for the manufacturer's selection, which enables the manufacturer to only have to use a uniform product for the spacer fabric unit.

A second and also important advantage for the user of the separability is that the two mat parts can be washed separately and the improved drying option. The separability means that the hygienically critical fleece mat can be washed at higher temperatures, while lighter washing programs are sufficient for the spacer fabrics made of synthetic fibers.

A third important aspect is the purity of the upper part of the mat with regard to possible processing. The lower part of the mat, which only includes the thin outer lamination layer, has a lower environmental impact if it is disposed of in landfill than the entire product. If necessary, the lamination layer can also be removed before disposal.

In the interests of improved reprocessability, it would of course be desirable for the lamination layer to be of a single type and of the same type as the spacer fabrics.

The quilted connection between the spacer fabrics advantageously prevents the use of adhesives.

For applying the lamination to the fleece mat, bonding methods that do not use the traditional flame lamination method will be preferred. For example, adhesive fibers that melt through thermal treatment can be incorporated into the lamination layer.

A preferred embodiment of the invention is presented below with reference to the drawings.

Fig. 1 shows a bed support mat according to the invention in plan view;

Fig. 2 shows a vertical partial section through the mat according to Fig. 1 according to the indicated cutting line.

Figure 1 shows a bed support mat 1 according to the invention in top view. The mat has a rectangular shape and can

be at least a little larger than the torso, so that the weight-bearing areas of a bedridden patient rest completely on the mat. However, the mat can also be the size of a mattress, so that the limbs that are less at risk of bedsores also rest on the mat. Details on the mat include a border 2 and quilted seams 3 running transversely to the lengthwise direction.

In Figure 2, the mat is shown in cross-section through an edge area. The opposite edge area is to be assumed in the same way. Otherwise, the mat has the structure shown uniformly in between. The previously mentioned edging 2 can be seen here as a zipper 4 with an upper fastening tab 5 and a lower fastening tab 6. The upper tab 5 is a unit consisting of an upper spacer fabric 7 and a middle spacer fabric 8, which are inseparably connected to one another at intervals by the quilting seams 3. The upper spacer fabric 7 is structured and has padding 9, which are separated by incisions 10. At least the outer layer 11 of the spacer fabric 7 consists of multifilament fibers, while the pile fibers 12 represent monofilament fibers. The lower layer 13 is preferably again made of multifilament fibers. For the spacer fabric 8, both the outer layers 14 and 16 as well as the pile fibers 15 consist of monofilament fibers.

The second fastening flap 6 of the zipper 4 is connected to a fleece mat 17, which is coated on the outside with a knitted layer 18, preferably made of polyethylene. The knitted layer 18 is in turn made waterproof by a coating 19, preferably made of polyurethane.

The fastening flap 5 of the zipper 4 is sewn to the spacer fabric with a seam 20; the fastening flap

6 of the zipper 4 is sewn to the coated fleece mat 17 with a seam 21. Between the unit made of the spacer fabrics and the fleece mat 17, an air gap 22 is shown, which is intended to illustrate that the two units can be detached from each other, whereby the zipper can be detached from each other all the way around the edging 2.
