Pneumatic reversible mattress for reducing the pressure exerted on tissue areas of in-patients.

p0001The invention relates to a pneumatic reversible mattress to relieve pressure vulnerable Gewebsbezirke at lying Kranken.Es is a Antidecubitusmatratze by alternately inflating and deflating of two mutually-related air chamber = systems a change in the support surface lie = gender Sick causes and thus the Entste = increase of pressure ulcers prevents.

p0002To prevent bedsores change = pressure mattresses are used that have two voneinan = the independent air chamber systems having a tubular shape and are mounted to extend transversely or longitudinally in parallel on the mattress - in a way that always two air chambers juxtaposed different luftkammersys = systems belong.

p0003When loading an air chamber system this is higher than in the other in such a way that between two air-filled chambers always an air emptied befindet.Durch changing air = feed both air chamber systems replaced the bearing surface of lying sick and causes a change pressure loaded Gewebspartien.

p0004Filling and emptying of both air chamber systems occur infrequently enough that as a fabric = damage can be long-term avoided.

p0005Alternating pressure mattresses only work optimally if they town.The contact with large areas of tissue of lying sick in the case of horizontal positioning of the patient, which can be for medical reasons but rarely carried out. Rather, it is often necessary to do = the patient with raised upper body lagern.Damit reduces the overlying tissue surface in substantially the gluteal region. The resulting here pressed against the alternating pressure mattress = can assume a size that exceeds the internal pressure of the air chambers =, compresses it, and thus the operating principle of the alternating pressure mattress overrides.

p0006Particularly vulnerable is the sacrum lying sick because bone and skin close together liegen.Die prevention of pressure ulcers = concerns mainly about these palm-sized Bezirk.Die Size commer = more alternating pressure mattresses stands in a Mißver = ratio to.

p0007Here will the invention Remedy schaffen.Die invention as is gekennzeich = net in the claims, solves the problem in that two side = by-side, not communicating with each air chamber systems that are interconnected by a vacuum holding web and have a special configuration , are alternately supplied with air that the resting patient performs a passive rotational movement in its longitudinal axis =, which leads to a permanent change of principal stress zones of the overlying tissue = lots.

p0008The alternating air feed both Luftkam = mersysteme via an air pump unit with motor-controlled deflection of air = streams, such as is used for the operation of commercial exchange = pressure mattresses.

p0009The short-term occurring passive Drehbewe = conditions of lying sick in its longitudinal axis cause frequent relocation of the main = load zones of the overlying Gewebsbezirke - especially Gesäßregion.Die prevention of pressure sores is so even when erect torso of lying sick certainly possible:

p0010An embodiment of the invention is illustrated in the drawings and in more detail below shows beschrieben.Es<ul><li>Figure 1 shows the airless pneumatic reversible mattress in Draufsicht.Sie ​​was exhibiting two übereinanderlie = lowing polythene of o, 2mm thickness Herge = that wurden.Zwei interconnected by means of a film welding device vertically = brought welds highlight in 1ocm spaced mattresses center: the holding web , In the transverse direction of the mattress extending welding seams in = 12cm distance from each said first and last weld beginning and end of the mattress markieren.Alle transverse welds - except start and end seam - are Mark twice 1cm length unterbrochen.Diese interruptions the middle of the right and left air chamber system and make air = penetration slots are that unite the individual chambers to air chamber systems. The air chambers are closed laterally by attaching two vertically extending welding seams =, one of which the left edge and the other the right edge of the mattress begrenzt.Linke and right lower chamber provided with an inlet connection, lets the air pass in both directions.</li><li>2, the mattress after filling both air = chamber systems by means of a Luftpumpenaggre = gats two hose connections.</li><li>Figure 3 the mattress with one side filled air chamber system - the other side is drained. A resting sick would have been through a passive turn left in this position.</li></ul>
