Description

Die Erfindung bezieht sich auf eine Matratze gemäß dem Oberbegriff des Hauptanspruches.The invention relates to a mattress according to the preamble of the main claim.

Eine gattungsbildende Matratze wird in dem DE-U-89 00 196 beschrieben. Hierbei besteht die eigentliche Matratze aus einer über die ganze Länge und den ganzen Querschnitt gleichbleibende Dichte aufweisenden Basismatratze aus Schaumstoff. Die Basismatratze weist eine Ausnehmung auf, die sich dabei im wesentlichen über die ganze Länge der Basismatratze erstreckt. In die Ausnehmung wird ein aus der EP-A-236 668 bekannter Polsterkörper aus mehreren Schaumstoffbahnen eingelegt.A generic mattress is described in DE-U-89 00 196. Here, the actual mattress consists of a base mattress made of foam over the entire length and the entire cross section. The base mattress has a recess which extends essentially over the entire length of the base mattress. A cushion body made of several foam sheets known from EP-A-236 668 is inserted into the recess.

Aus der DE-A-25 42 178 ist ein Kunstschaumpolsterkörper mit erhöhter Rand- bzw. Kantensteifigkeit bekannt, wobei an den Seitenflächen des Polsterkörpers hochstehende Schaumstoffplatten angeklebt werden, die eine feste Hautschicht aufweisen. Durch diese Anordnung soll die Formbeständigkeit im Randbereich eines Schaumstoffkörpers gesichert werden.From DE-A-25 42 178 an artificial foam cushion body with increased edge or edge rigidity is known, whereby upstanding foam sheets are glued to the side surfaces of the cushion body, that have a firm layer of skin. This arrangement is intended to ensure the dimensional stability in the edge region of a foam body.

An gute Matratzen werden heute eine Vielzahl sich häufig äußerlich widersprechender Anforderungen gestellt:
So ist eine gute Matratze nicht so hart, daß sie den Schläfer zu einer erhöhten Anzahl von Bewegungen zwingt, um die jeweils belasteten Körperteile zu entlasten.Today, good mattresses are subject to a variety of often contradictory requirements:
A good mattress is not so hard that it forces the sleeper to make an increased number of movements in order to relieve the stressed parts of the body.

Eine gute Matratze ist nicht so weich, daß sie Bewegungen und Hautatmung des Schläfers behindert.A good mattress is not so soft that it impedes the sleeper's movements and skin breathing.

Eine gute Matratze ist punktelastisch, d. h. sie gibt nur dort in jenem engbegrenzten Bereich nach, wo sie belastet wird. Sie bildet aber um diesen Belastungspunkt keine weitergehenden Kuhlen, sondern stützt bereits die Nachbarregion wieder ab.A good mattress is point elastic, i.e. H. it yields only in that narrowly defined area where it is stressed. However, it does not form any further hollows around this stress point, but already supports the neighboring region again.

Eine gute Matratze gibt also z. B. im Körperschwerpunkt unter Gesäß und Hüften nach, ist aber in der Lage, bereits im Lendenbereich wieder volle Stützung zu geben.A good mattress gives z. B. in the center of gravity under the buttocks and hips, but is able to give full support again in the lumbar area.

Außerdem muß eine gute Matratze den biomechanischen, d. h. den orthopädischen Anforderungen entsprechen und gleichzeitig die physiologischen, d. h. mikroklimatischen Anforderungen erfüllen.In addition, a good mattress must match the biomechanical, i.e. H. meet the orthopedic requirements and at the same time the physiological, d. H. meet microclimate requirements.

Der Erfindung liegt die Aufgabe zugrunde, die gattungsbildende Matratze dahingehend zu verbessern, daß mit nur wenigen Einzelteilen und wenig Arbeitsaufwand jederzeit die Matratze auf die besonderen Bedürfnisse des Benutzers eingestellt werden kann und ein individueller Liegekomfort geschaffen werden kann, der zur Gesundung beiträgt, Therapieziele unterstützt und Folgeerkrankungen vermeidet.The invention has for its object to improve the generic mattress so that the mattress can be adjusted to the special needs of the user at any time with just a few individual parts and little work and an individual lying comfort can be created that contributes to recovery, supports therapy goals and Avoids secondary diseases.

Diese der Erfindung zugrundeliegende Aufgabe wird durch die Lehre des Hauptanspruches gelöst.This object on which the invention is based is achieved by the teaching of the main claim.

Vorteilhafte Ausgestaltungen sind in den Unteransprüchen erläutert.Advantageous configurations are explained in the subclaims.

Mit anderen Worten ausgedrückt wird ein Matratzensystem vorgeschlagen, mit dem beste Voraussetzungen gegeben sind, den Patienten seinen individuellen Bedürfnissen entsprechend optimal lagern zu können, ohne dabei die Forderungen der Pflege an Hygiene, praxisgerechte Handhabung und Wirtschaftlichkeit vernachlässigen zu müssen.In other words, a mattress system It is proposed that the best conditions be given to be able to optimally position the patient according to his or her individual needs, without neglecting the hygiene requirements, practical handling and economy.

Das Funktionsprinzip des erfindungsgemäßen Systems besteht aus einer Basismatratze, die im Bereich der Liegefläche eine Aussparung aufweist. In diese Aussparung kann je nach medizinischer Situation des Patienten ein besonders gestalteter Matratzenkern mit unterschiedlichen Lagerungseffekten eingelegt werden. Im Bereich der Aussparung ist das Material der Basismatratze zudem stark verfestigt, so daß die Wirbelsäule immer ein festes Widerlager findet und gut abgestützt wird. Vervollständigt wird die jeweilige Matratzenkombination durch einen abnehmbaren Polsterbezug.The principle of operation of the system according to the invention consists of a base mattress which has a recess in the area of the lying surface. Depending on the patient's medical situation, a specially designed mattress core with different positioning effects can be inserted into this recess. In the area of the recess, the material of the base mattress is also strongly consolidated, so that the spine always finds a firm abutment and is well supported. The respective mattress combination is completed by a removable cushion cover.

Gemäß der Erfindung werden zwei Basismatratzen vorgeschlagen, bei denen die Forderung verwirklicht wird, die Vorteile einer harten Matratze für orthopädisch richtiges Liegen mit den Vorteilen einer weichen Matratze für komfortables, gewebeentlastetes Liegen zu verbinden. Für den gewerblichen Einsatzzweck ermöglicht das erfindungsgemäße Matratzensystem, daß mit wenigen Einzelteilen und wenig Pflegeaufwand jederzeit auf die besonderen Bedürfnisse des Patienten eingegangen werden kann. Eine individuelle Lagerung trägt zur Gesundung bei, unterstützt Therapie- und Pflegeziele und hilft Folgeerkrankungen zu vermeiden.According to the invention, two basic mattresses are proposed in which the requirement is met to combine the advantages of a hard mattress for orthopedically correct lying with the advantages of a soft mattress for comfortable, tissue-relieved lying. For commercial use, the mattress system according to the invention enables the special needs of the patient to be addressed at any time with a few individual parts and little maintenance. Individual storage contributes to recovery, supports therapy and care goals and helps to avoid secondary diseases.

Die Basismatratze kann dabei 14 cm hoch sein und eine 70 x 90 x 7 cm große Aussparung im Liegebereich für den individuell einlegbaren Matratzenkern aufweisen.The base mattress can be 14 cm high and have a 70 x 90 x 7 cm recess in the lying area for the individually insertable mattress core.

Die Stauchhärten der Basismatratzen sind entsprechend den unterschiedlichen Belastungszonen einer funktionellen Pflegematratze ausgebildet. Sie ist sehr weich im Fußbereich, um den Fersenauflagedruck zu reduzieren, weist feste Seitenbereiche auf, die ein sicheres Sitzen des Patienten, z. B. bei Mobilisationsbemühungen, ermöglichen. Im Aussparungsbereich, d. h. im Bereich der Ausnehmung, ist die Basismatratze zur guten Wirbelsäulenunterstützung sehr fest.The compression hardness of the base mattresses is designed according to the different load zones of a functional care mattress. It is very soft in the foot area to reduce the heel pressure, has fixed side areas that ensure a safe sitting of the patient, e.g. B. in mobilization efforts. In the recess area, i.e. H. in the area of the recess, the base mattress is very firm for good spine support.

Gemäß einem ersten Merkmal der Erfindung kann die Basismatratze aus einem Polyurethanschaumstoffverbund bestehen, der der Matratze eine hohe Dauerbelastbarkeit und lange Lebensdauer verleiht. Die ausgezeichnete Klimaregulierung wird durch die Luftzellen des Polyurethanmaterials sowie durch eine zusätzliche rapportmäßig angelegte Röhrenstanzung über die gesamte Fläche der Matratze erreicht.According to a first feature of the invention, the base mattress can consist of a polyurethane foam composite, which gives the mattress a high durability and a long service life. The excellent climate regulation is achieved through the air cells of the polyurethane material as well as through an additional, repeatable tube punching over the entire surface of the mattress.

Gemäß einem anderen Merkmal der Erfindung besteht die Basismatratze aus einem Faserkern aus Hohlfasern. Diese Hohlfasern stellen speziell gekräuselte Fasern dar, die in ihrer gesamten Länge von vier Kanälen durchzogen werden. Dieser Aufbau verleiht der Faser elastisch federnde Eigenschaften bei guter Stabilität und macht sie außerdem luft- und wasserdampfdurchlässig. Für die Herstellung der erfindungsgemäßen Matratze werden viele Lagen von Hohlfaservliesen thermisch miteinander verbunden und im Ausnehmungsbereich extrem verfestigt. So entsteht eine Matratze mit einer außergewöhnlichen Biegesteifigkeit und einer gleichzeitig guten Druckelastizität. Sie gibt damit bei Belastungen dem Druck nach, ohne sich jedoch zu verbiegen und durchzuhängen.According to another feature of the invention, the base mattress consists of a fiber core made of hollow fibers. These hollow fibers are specially crimped fibers that are traversed by four channels along their entire length. This structure gives the fiber resilient properties with good stability and also makes it permeable to air and water vapor. For the manufacture of the mattress according to the invention, many layers of hollow fiber nonwovens are thermally bonded to one another and extremely solidified in the recess area. This is how it is created a mattress with exceptional flexural rigidity and good elasticity at the same time. It therefore yields to pressure when subjected to loads, but without bending and sagging.

Diese Matratze ist somit hervorragend für Patienten, die zur Wirbelsäulenabstützung ein sehr festes Widerlager brauchen, geeignet.This mattress is ideal for patients who need a very firm abutment to support the spine.

Gemäß der Erfindung wird weiterhin vorgeschlagen, daß der Matratzenkern in einem Gewebebezug eine Füllung aus rhombisch geschnittenen Luftzellenstäbchen aus Polyurethanschaum aufweist. Dieser Matratzenkern mit seiner hochelastischen Füllung bewirkt eine gute Druckentlastung und bietet außergewöhnlichen Liegekomfort. Diese Art des Matratzenkerns kommt bei der Lagerung dekubitusgefährdeten Patienten zur Anwendung, eignet sich aber auch bestens zur Lagerung von Patienten mit ausgeprägten Schmerzzuständen, z. B. bei Beschwerden des rheumatischen Formenkreises. Die Patienten liegen weich, wobei sich durch die ständige Luftzirkulation in den Luftzellenstäbchen eine wohltuende, gleichbleibend trockene Wärme ohne Wärmestau und Kältebrücken ergibt. Trotzdem werden aber die Patienten und Matratzenbenutzer sicher und wirbelsäulengerecht gelagert. Sie "versinken" nicht in der Matratze, was große pflegerische Bedeutung hat.According to the invention it is further proposed that the mattress core has a filling made of rhombic-cut air cell sticks made of polyurethane foam in a fabric cover. This mattress core with its highly elastic filling provides good pressure relief and offers exceptional comfort. This type of mattress core is used for the storage of pressure sensitive patients, but is also ideal for positioning patients with pronounced pain conditions, e.g. B. for complaints of the rheumatic type. The patients lie softly, whereby the constant air circulation in the air cell sticks results in a pleasant, consistently dry heat without heat build-up and cold bridges. Nevertheless, the patients and mattress users are stored safely and in accordance with the spine. They do not "sink" into the mattress, which is of great care.

Weiterhin wird vorgeschlagen, als Matratzenkern zwei Schaumstoffbahnen unterschiedlichen Raumgewichtes und Stauchhärten einzusetzen. Durch diesen Materialaufbau ergibt sich ein bestimmtes Elastizitätsverhalten, das ein dosiertes Einsinken des Körpers erlaubt. Er wird weich aufgenommen und stößt beim weiteren Einsinken auf immer höheren Widerstand, bis er schließlich durch das feste Widerlager der Basismatratze abgestützt wird. Dieser Lagerungseffekt wird durch die hohe Punktelastizität des Materials verstärkt, denn der Schaumstoff gibt nur dort nach, Wo er auch belastet wird. In Rückenlagen kann z. B. das Gesäß in den Matratzenkern einsinken, während gleichzeitig die Lendenwirbelsäule abgestützt wird. In Seitenlage können sich Hüft- und Schulterbereiche so einmodulieren, daß die Wirbelsäule bei einer leichten Dehnung im Lendenwirbelbereich möglichst gerade verläuft.It is also proposed to use two foam webs of different density and compression hardness as the mattress core. This material structure results in a certain elasticity behavior, which allows a dosed sinking of the body. It is absorbed softly and meets increasing resistance as it sinks further, until it is finally supported by the fixed abutment of the base mattress. This storage effect is reinforced by the high point elasticity of the material, because the foam only gives way where it is loaded. In supine positions z. B. sink the buttocks into the mattress core while supporting the lumbar spine. In the lateral position, the hip and shoulder areas can modulate in such a way that the spine is as straight as possible with a slight stretch in the lumbar area.

Entspannte Lagerung, Entlastung und leichte Dehnung führen dann insgesamt zu einem verbesserten Stoffwechsel der Bandscheiben mit der Chance einer intensiven Erholung während der Liegephase.Relaxed storage, relief and slight stretching then lead to an improved metabolism of the intervertebral discs with the chance of an intensive recovery during the lying phase.

Die gemäß der Erfindung vorgesehenen Polsterbezüge weisen eine 15 mm starke Schaumstoffeinlage auf, die vorzugsweise gemäß der Vorschrift des EP-B1-236 668 ausgebildet ist.The cushion covers provided according to the invention have a 15 mm thick foam insert, which is preferably designed according to the regulation of EP-B1-236 668.

Diese Polsterschicht und die weichen, vorzugsweise hautsympatischen Bezugsstoffe sind durch Längssteppung miteinander verbunden. Alle verwendeten Bezugsstoffe sind elastisch, damit sie mit der Elastizität der Matratzenkerne harmonieren können und die Faltenbildung minimiert wird.This cushioning layer and the soft, preferably skin-friendly upholstery fabrics are connected to each other by longitudinal stitching. All cover fabrics used are elastic so that they can harmonize with the elasticity of the mattress core and the formation of wrinkles is minimized.

In Fig. 1 ist eine Basismatratze 1 schematisch ohne Polsterbezug dargestellt. Diese Basismatratze 1 besteht aus Polyurethanschaumstoffverbund oder einem Gemisch von Hohlfasern, die in ihrer gesamten Länge von Kanälen durchzogen sind. Beide Matratzenarten weisen ein relativ niedriges Gewicht auf, so daß sie gut handhabbar sind. Sie erzeugen keinen Staub und eignen sich daher ideal für Personen, die an entsprechenden Allergien leiden. Wird die Basismatratze 1 aus Polyurethanschaum hergestellt, kann, um eine noch bessere Klimatisierung zu erreichen, die gesamte Fläche zusätzlich mit einer in der Zeichnung nicht dargestellten Röhrenstanzung versehen werden. Derartige, aus Polyurethanschaum hergestellte Matratzen können auch leicht abgewinkelt werden.In Fig. 1, a base mattress 1 is shown schematically without a cushion cover. This base mattress 1 consists of polyurethane foam composite or a mixture of hollow fibers, which are traversed in their entire length by channels. Both types of mattress have a relatively low weight, so that they are easy to handle. They do not generate dust and are therefore ideal for people who suffer from allergies. If the base mattress 1 is made of polyurethane foam, in order to achieve even better air conditioning, the entire surface can additionally be provided with a tube punching (not shown in the drawing). Such mattresses made of polyurethane foam can also be angled slightly.

Die Basismatratze 1 übernimmt die stützende Funktion und weist im Körperliegebereich 14 eine Ausnehmung 5 auf, die sich mindestens über die gesamte Länge der Wirbelsäule erstreckt. Besteht die Basismatratze aus einem Faserkern, ist der Bereich der Ausnehmung 5 extrem hart, während der Restbereich, d. h. der Bein-Fußbereich 12 und der Kopfbereich 15 weicher ist. Der Bereich der Ausnehmung 5 weist beispielsweise eine Rohdichte von 60 kg/m³ auf, während der Restbereich eine Rohdichte von 40 kg/m³ besitzt. Hierbei weist eine Randleiste 6 neben der Ausnehmung 5 oder ggf. im ganzen Basismatratzenbereich auch eine höhere Rohdichte auf und ermöglicht ein sicheres Sitzen des Patienten.The base mattress 1 takes on the supporting function and has a recess 5 in the body lying area 14 which extends at least over the entire length of the spine. If the base mattress consists of a fiber core, the area of the recess 5 is extremely hard, while the remaining area, ie the leg-foot area 12 and the head area 15, is softer is. The area of the recess 5 has, for example, a bulk density of 60 kg / m³, while the remaining area has a bulk density of 40 kg / m³. In addition to the recess 5 or possibly in the entire base mattress area, an edge strip 6 also has a higher bulk density and enables the patient to sit securely.

Besteht die Basismatratze 1 aus einem Polyurethanschaumstoff, sind die Stauchhärten ebenfalls entsprechend den unterschiedlichen Belastungszonen ausgebildet und ergeben so eine funktionelle Pflegematratze.If the base mattress 1 consists of a polyurethane foam, the compression hardnesses are also designed in accordance with the different load zones and thus result in a functional care mattress.

In die Ausnehmung 5 wird ein Matratzenkern 7 eingelegt, der z. B. in drei unterschiedlichen Qualitäten ausgebildet sein kann:In the recess 5, a mattress core 7 is inserted, the z. B. can be trained in three different qualities:

Einmal kann dieser Matratzenkern 7 aus in einen Bezug 11 eingefüllten rhombisch geschnittenen Luftzellenstäbchen aus Polyurethanschaum bestehen.On the one hand, this mattress core 7 can consist of rhombic-cut air cell sticks made of polyurethane foam filled into a cover 11.

Zum andern können in einem entsprechend ausgebildeten Bezug 11 zwei Schaumstoffbahnen 9, 10 untergebracht sein, die unterschiedliche Rohdichte und Härte aufweisen und progressiv aufeinander abgestimmt sind. Die Schaumstoffbahnen 9, 10 sind dabei vorzugsweise mit im Abstand voneinander angeordneten, die Schaumstoffbahnen 9 und 10 geradlinig und ganz, d. h. von der Ober- bis zur Unterseite durchquerenden Stanzschnitten ausgerüstet. Die Stanzschnitte sind dabei rechtwinklig zueinander angeordnet und senkrecht zur Oberfläche der Schaumstoffbahn 9 und 10 geführt. Beide Schaumstoffbahnen 9 und 10 sind punkt- oder strichförmig materialschlüssig miteinander verbunden.On the other hand, two foam sheets 9, 10 can be accommodated in a suitably designed cover 11, which have different bulk density and hardness and are progressively coordinated with one another. The foam webs 9, 10 are preferably equipped with punch cuts arranged at a distance from one another, the foam webs 9 and 10 in a straight line and completely, ie from the top to the bottom. The die cuts are arranged at right angles to one another and guided perpendicular to the surface of the foam web 9 and 10. Both foam webs 9 and 10 are material or dot-shaped connected with each other.

Schließlich kann der Matratzenkern 7 auch aus einem in einem Bezug 11 angeordneten Gemisch aus rhombisch geschnittenen Luftzellenstäbchen aus Polyurethanschaumstoff und Polypropylenpolsterperlen bestehen.Finally, the mattress core 7 can also consist of a mixture of rhombic-cut air cell sticks made of polyurethane foam and polypropylene cushion beads arranged in a cover 11.

Anstatt eines Matratzenkerns 7 können auch zwei einzelne Einlegekissen 16 und 17 vorgesehen werden (Fig. 5).Instead of a mattress core 7, two individual insert pillows 16 and 17 can also be provided (FIG. 5).

Anstatt eines Polsterkissens als Matratzenkern kann ein Wasserkissen oder ein Gelkissen eingesetzt werden.Instead of an upholstered cushion as a mattress core, a water cushion or a gel cushion can be used.

Diese Matratzenkerne 7 sorgen für den Liegekomfort und können den individuellen Gegebenheiten angepaßt werden. Trotz der unterschiedlichen Ausgestaltung der Matratzenkerne 7 wird immer gewährleistet, daß das orthopädisch richtige Prinzip der Weich- und Hartlagerung zum Tragen kommt, d. h. es wird ein kurzer Federweg gewährleistet, trotzdem eine gute Modellation und dabei stark abstützend. Entscheidend ist auch, daß die Basismatratze 1 nicht schwingend arbeitet oder nachfedert.These mattress cores 7 ensure lying comfort and can be adapted to the individual circumstances. Despite the different design of the mattress cores 7, it is always ensured that the orthopedically correct principle of soft and hard positioning comes into play, i. H. a short spring travel is guaranteed, nevertheless a good modeling and strong support. It is also crucial that the base mattress 1 does not vibrate or rebound.

Die Ausnehmung 5 wird zu beiden Längsseiten hin durch Randbereiche 6 begrenzt, die beispielsweise eine Breite von 10 cm aufweisen. Die Tiefe der Ausnehmung 5 beträgt z. B. 7 cm, so daß immer noch ein genügender Tragkörper im Körperliegebereich 14 der eigentlichen Basismatratze 1 gewährleistet ist.The recess 5 is delimited on both long sides by edge regions 6, which have a width of 10 cm, for example. The depth of the recess 5 is z. B. 7 cm, so that a sufficient support body in the body lying area 14 of the actual base mattress 1 is still guaranteed.

Die Oberseite der gesamten Basismatratze 1 kann eine Struktur aufweisen, so daß hier eine gewisse Rutschfestigkeit erzielt wird und gleichzeitig auch eine gute Belüftung. Dies wird auch durch eine ggf. vorgesehene Noppenstruktur erreicht.The top of the entire base mattress 1 can have a structure, so that a certain slip resistance is achieved here and at the same time one good ventilation. This is also achieved by a nub structure that may be provided.

Die Gesamtkombination aus Basismatratze 1 und Matratzenkern 7 wird von einem Polsterbezug 8 umgeben. Dieser Polsterbezug 8 kann aus Schaumstoffbahnen bestehen und machen an sich aus der zweiteiligen Matratzenkombination eine einteilige Matratze. Dieser Polsterbezug 8 weist vorzugsweise einen hautsympatischen Bezugsstoff auf, der durch Längssteppung mit der von ihm aufgenommenen Schaumstoffbahn verbunden ist. Vorzugsweise sind die verwendeten Bezugsstoffe für den Polsterbezug 8 elastisch, damit sie mit der Elastizität der Matratzenkerne harmonieren können und die Faltenbildung minimiert wird. Der Bezug für den Polsterbezug 8 ist durchgängig, vorzugsweise an drei Seiten mit einem zweiteiligen Reißverschluß versehen und somit kann der Polsterbezug 8 problemlos gewechselt werden.The overall combination of base mattress 1 and mattress core 7 is surrounded by a cushion cover 8. This cushion cover 8 can consist of foam sheets and in itself make the two-part mattress combination a one-piece mattress. This upholstery cover 8 preferably has a skin-friendly cover material, which is connected by longitudinal stitching to the foam web that it has received. The cover materials used for the cushion cover 8 are preferably elastic so that they can harmonize with the elasticity of the mattress cores and the formation of wrinkles is minimized. The cover for the upholstery cover 8 is continuous, preferably provided on two sides with a two-part zip, and thus the upholstery cover 8 can be changed without problems.
