Description

Die Erfindung betrifft eine Badevorrichtung insbesondere für physisch beeinträchtigte Personen mit einer mit Badewasser befüllbaren Badewanne und einer Hubfläche zum Anheben und Absenken einer in der Badewanne befindlichen Person.The invention relates in particular to a bathing device for physically impaired people with a bath water fillable bathtub and a lifting surface for lifting and lowering one in the bath Person.

Badevorrichtungen dieser Art sollen das Baden vor allem für solche Personen erleichtern, die aufgrund einer körperlichen Beeinträchtigung nicht imstande sind, über den Rand einer herkömmlichen Wanne zu treten. Dabei ist es bekannt, die Hubfläche durch eine starre Hubplatte zu realisieren, welche durch hydraulisch arbeitende Teleskopzylinder bewegbar ist. Diese Anordnung läßt sich gegebenenfalls als Baueinheit in eine Badewanne einsetzen. Hierbei hat es sich jedoch herausgestellt, daß eine starre Hubplatte ergonomisch nicht ausreichend anpaßbar ist, was insbesondere von Kranken mit Liegeschäden als nachteilig empfunden wird und bei Epilepsiekranken zu Verletzungen führen kann. Hinzu kommt ein beträchtlicher Bauaufwand für die Hubvorrichtung, die zudem aufgrund der ausgeprägten Technizität häufig in psychologischer Hinsicht nachteilig auf Patienten wirkt.Bathing devices of this type are intended primarily for bathing easier for those who have physical problems Are not able to impair over the Kicking edge of a conventional tub. It is known to increase the lifting surface by a rigid lifting plate realize which by hydraulically operating telescopic cylinders is movable. This arrangement can, if necessary insert as a unit in a bathtub. Here, however, it has been found that a rigid Lifting plate is not ergonomically adaptable, which is particularly disadvantageous for patients with damaged beds perceived and injuries in epilepsy patients can lead. In addition, there is a considerable amount of construction work for the lifting device, which is also due to the pronounced technicity often in psychological terms adversely affects patients.

Dokument DE-A-41 06 524 offenbart eine Badevorrichtung mit allen im Oberbegiff des Anspruchs 1 definierten Merkmalen.Document DE-A-41 06 524 discloses a bathing device with all features defined in the preamble of claim 1.

Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, eine Badevorrichtung der eingangs angegebenen Art dahingehend zu entwickeln, daß mit einfachen Mitteln eine patientenfreundliche Benutzung ermöglicht wird.Proceeding from this, the invention is based on the object a bathing device of the type specified above to develop that with simple means patient-friendly use is made possible.

Zur Lösung dieser Aufgabe wird die im Patentanspruch 1 angegebene Merkmalskombination vorgeschlagen. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.To solve this problem is the in claim 1 specified combination of features proposed. advantageous Refinements and developments of the invention result themselves from the dependent claims.

Die Erfindung geht von dem Gedanken aus, die Hubfläche in einer Doppelfunktion als Huborgan und Bademulde körpergerecht zu gestalten. Dies wird erfindungsgemäß dadurch erreicht, daß die Hubfläche durch eine flexible Hubmatte gebildet ist, welche eine mit einem Arbeitsfluid beaufschlagbare Stützwanne im Bereich ihrer nach oben weisenden Wannenöffnung druckdicht überspannt und unter Änderung des Arbeitsfluidvolumens in der Stützwanne als Badewanne senk- und hebbar ist. Der Patient ist damit ergonomisch gestützt, und die Hubbewegung wird ohne aufwendige und im Naßbereich gegen Verschmutzung anfällige Hubmechanik ermöglicht.The invention is based on the idea that the lifting surface in a double function as a lifting organ and bath trough to design. This is achieved according to the invention by that the lifting area by a flexible lifting mat is formed, which can be acted upon with a working fluid Support trough in the area of their upward facing Trough opening spanned pressure-tight and under change of the working fluid volume in the support tub as a bathtub can be lowered and raised. The patient is therefore ergonomic supported, and the lifting movement is without expensive and lifting mechanism susceptible to contamination in the wet area allows.

Gemäß einer besonders bevorzugten Ausgestaltung der Erfindung ist die Hubmatte gummielastisch dehnbar ausgebildet, wobei sie sich beim Absenken unter Dehnung an die Körperkontur der Person anschmiegt und eine mit Badewasser befüllbare, in ihren Abmessungen optimal an die Person angepaßte Mulde bildet.According to a particularly preferred embodiment of the invention the lifting mat is designed to be elastically stretchable, while stretching to the Body contour hugs the person and one with bath water fillable, their dimensions optimal to the person adapted trough forms.

Um Dehnbewegungen im Bereich der badenden Person zu reduzieren und die Person definiert abzustützen, ist es günstig, wenn die Hubmatte bereichsweise durch ein Aussteifungselement verstärkt ist.To reduce stretching movements in the area of the bathing person and to support the person in a defined way, it is beneficial if the lifting mat is partially covered by a stiffening element is reinforced.

Die Benutzung und auch die Reinigung wird dadurch weiter erleichtert, daß die Hubmatte in einer oberen Stellung die Wannenöffnung vorzugsweise unter außenkonvexer Wölbung glatt überspannt.The use and cleaning will continue relieved that the lifting mat in an upper position the trough opening preferably under an external convex curvature smoothly spanned.

Weiter ist es von Vorteil, wenn die Hubmatte die Person unter Eigenspannung trägt und durch Abpumpen von in der Stützwanne befindlichem Arbeitsfluid absenkbar ist. Damit wird ein ungewolltes Absenken der Person vermieden und das Volumen der Bademulde exakt einstellbar, während die Person mit ihrem Eigengewicht im wesentlichen nur die spezielle Ausformung der Mulde beeinflußt.It is also advantageous if the lifting mat is the person under internal stress and by pumping out in the Support pan located working fluid can be lowered. In order to an unwanted lowering of the person is avoided and the volume of the bath trough is precisely adjustable, while the Person with their own weight essentially only that special shape of the trough influenced.

Um die erforderliche Dehnbarkeit zu gewährleisten, besteht die Hubmatte vorteilhafterweise aus einem Siliconmaterial, vorzugsweise aus Siliconkautschuk, oder aus Gummi oder aus einem gummielastisch dehnbaren Elastomer.In order to ensure the required elasticity, there is the lifting mat advantageously made of a silicone material, preferably made of silicone rubber, or Rubber or from a rubber-elastic stretchable elastomer.

Um die Handhabung bzw. Montage der Hubmatte zu erleichtern, ist es von Vorteil, wenn die Hubmatte im Bereich ihres Außenrandes einen umlaufenden Halterahmen aufweist.To make handling and assembly of the lifting mat easier, it is beneficial if the lifting mat is in the area its outer edge has a circumferential holding frame.

Eine konstruktiv vorteilhafte Ausführung sieht vor, daß die Hubmatte mit dem die Wannenöffnung begrenzenden Rand der Stützwanne umlaufend druckdicht verbunden ist. Hierfür können der Rand der Stützwanne eine Profilnut und die Hubmatte eine in der Profilnut formschlüssig gehaltene Randwulst aufweisen, wobei ein an die Randwulst angrenzender Randstreifen der Hubmatte eine Nutflanke der Profilnut druckdicht umspannt.A constructively advantageous embodiment provides that the lifting mat with the edge delimiting the tub opening the support trough is connected pressure-tight all around. Therefor can the edge of the support trough a profile groove and the Lifting mat is held in the profile groove in a form-fitting manner Have edge bead, one adjacent to the edge bead Edge strip of the lifting mat a groove flank of the profile groove spanned pressure-tight.

Vorteilhafterweise weist die Stützwanne eine um die Wannenöffnung umlaufende Überlaufrinne für Badewasser auf, welche in einen Abflußkanal mündet. Damit fließt das Badewasser beim Anheben der Hubmatte selbsttätig ab, ohne daß hierfür besondere Armaturen erforderlich wären. Alternativ oder ergänzend ist es auch möglich, daß die Hubmatte vorzugsweise in ihrem Zentralbereich eine durch ein Verschlußstück dicht verschließbare Abflußöffnung aufweist, über welche das Brauchwasser unter Schwerkraftwirkung ableitbar ist.The support trough advantageously has a around the trough opening all-round overflow channel for bathing water, which opens into a drainage channel. The bath water flows with it automatically when lifting the lifting mat, without that special fittings would be required for this. alternative or in addition, it is also possible that the lifting mat preferably in their central area one by one Closure piece has tightly closable drain opening, through which the process water under gravity can be derived.

In einer baulich besonders einfachen Ausführung ist es vorgesehen, daß das Arbeitsfluid durch Luft gebildet ist, und daß ein Gebläse zum Fördern von Luft zwischen dem Stützwannenraum und der umgebenden Atmosphäre angeordnet ist. Dabei kann das Gebläse durch zwei in einer den Stützwannenraum mit der umgebenden Atmosphäre verbindendenden Förderleitung in Reihe angeordnete Gebläseeinheiten gebildet sein, welche im Wechselbetrieb mit entgegengesetzter Förderrichtung arbeiten, um die Hubmatte abzusenken oder anzuheben.It is in a particularly simple construction provided that the working fluid is formed by air, and that a fan for conveying air between the Support tub space and the surrounding atmosphere is. The fan can be replaced by two in one Support tub space connecting with the surrounding atmosphere Delivery line blower units arranged in series be formed, which in alternating operation with opposite Work the conveying direction to lower the lifting mat or raise.

Um eine besonders in ökonomischer Hinsicht vorteilhafte Betriebsweise zu ermöglichen, sind ein Speicherbehälter für Arbeitsfluid und eine Förderanordnung zum wahlweisen Fördern des Arbeitsfluids in einem geschlossenen Kreislauf zwischen dem Speicherbehälter und der Stützwanne vorgesehen. Dabei ist es günstig, wenn das Arbeitsfluid durch eine Arbeitsflüssigkeit, vorzugsweise Wasser gebildet ist und die Förderanordnung eine Flüssigkeitspumpe, vorzugsweise eine Kreiselradpumpe zur Förderung der Arbeitsflüssigkeit aufweist. Das Umpumpen von Arbeitsflüssigkeit läßt sich dadurch steuern, daß die Förderanordnung mindestens ein Wegeventil zur Fließwegumkehr des Arbeitsfluids zwischen dem Speicherbehälter und der Stützwanne aufweist. Zur Bedienungserleichterung ist es weiter vorteilhaft, wenn die Förderanordnung eine von einer auf der Hubmatte befindlichen Person bedienbare Steuereinrichtung zur Steuerung der Arbeitsfluidförderung aufweist.To a particularly advantageous in economic terms To allow operation, are a storage tank for working fluid and a delivery arrangement for optional Pumping the working fluid in a closed circuit between the storage tank and the support pan intended. It is beneficial if the working fluid formed by a working fluid, preferably water and the conveyor arrangement is a liquid pump, preferably a centrifugal pump for pumping the working fluid having. Pumping of working fluid can be controlled in that the conveyor arrangement at least one directional control valve for reversing the flow path of the working fluid between the storage tank and the support pan having. It is further to make operation easier advantageous if the conveyor arrangement is one of one control device located on the lifting mat to control the working fluid delivery.

In einer besonders kompakten Bauform trennt die Wandung der Stützwanne den mit dem Arbeitsfluid beaufschlagbaren Stützwannenraum von dem Speicherbehälter. Eine weitere Verbesserung auch in gestalterischer Hinsicht läßt dadurch erreichen, daß die Stützwanne, der Speicherbehälter und die Förderanordnung in einem gemeinsamen Wannengehäuse angeordnet sind. Dabei ist es günstig, wenn das Wannengehäuse und die Stützwanne als einstückiges Kunststoff-Formteil vorzugsweise aus Polyethylen ausgebildet sind.The wall separates in a particularly compact design the support trough to which the working fluid can be applied Support pan space from the storage tank. Another This also allows improvement in terms of design reach the support pan, the storage tank and the conveyor arrangement in a common tub housing are arranged. It is beneficial if the tub housing and the support trough as a one-piece plastic molding preferably made of polyethylene are.

Zur weiteren Verbesserung der Benutzungsfreundlichkeit ist eine vorzugsweise als in die Stützwanne einlegbare Heizmatte ausgebildete Heizvorrichtung zum Erwärmen des Arbeitsfluids vorgesehen. To further improve usability is preferably one that can be inserted into the support trough Heating mat trained heating device for heating the Working fluids provided.
