DE19516880A1 - Therapeutic mattress for treating skin problems of bedridden patients - Google Patents

Abstract

The mattress has a flexible, permeable membrane (10 ts lying surface, through which materials can diffuse from a medium (2) to the exterior. The quantity of the medium beneath the permeable membrane is minimised by anatomically shaping the underbody (3) of the mattress. The mattress can be enclosed by a germ-tight and water-tight casing (5). The membrane can be set in vibration above the medium by a vibration source (9). It can be temp. controlled by a heating and cooling arrangement (4) contg. an earthed electrically conducting heating plate.

Description

For the treatment of skin defects of bedridden patients as aids that primarily serve to relieve pressure, skins, Foam pads, pressure change mattresses, water beds, Air cushions / beds, reversible beds, etc. known.

The disadvantages of these products are poor hygiene, missing or insufficient temperature regulation, the missing Possibility to administer medication through the skin to be able to and the often unwieldy construction. It is further not possible to shower the patient on it.

The present invention has set itself the task of a To create therapy mattress, the above. Avoids disadvantages and combines the following properties:

Hygiene, medication application, pressure relief, vibration, Temperature control, the possibility of showering the patient and lightweight construction with dimensions of a usual mattress and thus on every bed fitting.

Fig. 1 shows a therapy mattress, whose main feature is a flexible permeable membrane 1 in the lying area, which surrounds a pan body 3 as germs and water-tight envelope 5 in the further course. Under the membrane 1 is the tub body 3 , the z. B. is made of foam. Inside is a liquid-tight sack 6 , which connects to the membrane 1 in the edge region 7 . Active substances from the liquid medium 2 diffuse through the membrane 1 on the outside thereof and, depending on the active substance, create conditions for sterility and healing there. Depending on the concentration of the medium 2 and the permeability of the membrane 1 , a desired permanent active state is achieved. The flexible permeable membrane 1 in connection with the medium 2 gives the patient 8 buoyancy and even weight distribution with minimized specific contact pressures, the permeable membrane conforming to the body contour of the patient 8 . This ensures good skin contact for the permeable membrane 1 and thus for the active substances from the medium 2 . As a further therapeutic option, the membrane 1 can be set in vibration by means of vibration source 9 via medium 2 . The anatomically adapted shape of the tub body 3 minimizes the medium 2 and thus the total weight of the therapy mattress. The medium 2 can be temperature-controlled by the heating / cooling device 4 placed under the sack 6 .

FIG. 2 shows the metallic heat exchange plate 1 of the heating / cooling device 4 from FIG. 1 under the medium 2 of the therapy mattress from FIG. 1. It is provided with an earth connection 3 and thus shields the patient against the influence of electrical components. The heat exchange plate 1 forms a structural unit with the temperature sensor 4 . On the heat exchange plate 1 there are the heating / cooling elements 6 .

Fig. 2, for example, a space-saving arrangement of the elements. In the area under the temperature sensor 4, the surface 5 of the heat exchange plate 1 is minimized in the material thickness to ensure a good heat transfer to the medium 2. If a thermally conductive medium 2 is available in sufficient quantity, the temperature of the medium 2 is measured by the temperature sensor 4 through the surface 5 . If the medium 2 is not available, the temperature transfer from the heating / cooling elements 6 via the heat exchange plate 1 and the surface 5 to the temperature sensor 4 is given and a safety thermostat switches z. B. from overheating.
