Description

Die Erfindung bezieht sich auf eine Spital-Badewanne enthaltend einen Wannenkörper und eine elektrohydraulisch betriebene Hebevorrichtung mit Hydraulikzylinder, Kolbenstange und Motor-Pumpen-Aggregat zum Heben und Senken einer Sitz- oder Liegeanordnung, die zwischen einer Stellung ausserhalb des Wannenkörpers und einer Stellung innerhalb des Wannenkörpers bewegbar ist. Solche Spital-Badewannen sind allgemein in der Kranken- und Alterspflege anwendbar. Insbesondere sind sie aber zur Benützung durch Patienten und Behinderte bestimmt, die aufgrund ihres körperlichen Zustandes nicht ohne fremde Hilfe in handelsübliche, oft auf die ergonomischen Bedürfnisse des Pflegepersonals abgestimmte Badewannen gelangen können.The invention relates to a hospital bathtub containing a tub body and an electrohydraulically operated lifting device with a hydraulic cylinder, piston rod and motor-pump unit for lifting and lowering a seat or lying arrangement, which is between a position outside the tub body and a position within the tub body is movable. Such hospital bathtubs are generally applicable in nursing and elderly care. In particular, however, they are intended for use by patients and disabled people who, due to their physical condition, cannot get into commercially available bathtubs that are often tailored to the ergonomic needs of nursing staff without outside help.

Es ist bekannt, dass der Badebetrieb in der Alterspflege und bei Querschnittgeschädigten zu einem pflegerisch grossen Problem herangewachsen ist, nachdem die medizinische Betreuung durch Medikamente aller Art stark reduziert werden konnte und Bewegungsaktivitäten durch mechanische Hilfsmittel auf einen relativ hohen Stand gebracht werden konnten. Das Überführen von Patienten in Badewannen stellt unter diesen Aspekten das Hauptproblem dar, denn einerseits sollte die Badewanne für das Bedienungs- und Pflegepersonal auf einer ergometrisch richtigen Arbeitshöhe von etwa 80 cm über Boden sein, und andererseits ist es auch für « aktivierte ältere Personen häufig nicht möglich, selbst in eine 60 cm über Boden stehende Badewanne zu gelangen.It is known that bathing in geriatric care and with cross-sectional injuries has grown into a major problem after long-term medical care with medication of all kinds has been greatly reduced and movement activities with mechanical aids have been brought to a relatively high level. The transfer of patients into bathtubs is the main problem from this point of view, because on the one hand the bathtub should be at an ergonomically correct working height of about 80 cm above the floor for the operating and nursing staff, and on the other hand it is often not even for «activated elderly people possible to get into a bathtub standing 60 cm above the floor.

Die heute zur Verfügung stehenden Hilfsmittel für die Überführung von Behinderten der genannten Art in und aus Badewannen sind vorwiegend aus herkömmlichen Hebetechniken übernommen und im Stückwerk zu einer Anlage zusammengebaut worden, die eine einheitliche Konzeption vermissen lässt. So offenbart z. B. das US-Patent Nr. 3,071,779 eine Badewanne mit einem Badewannenlift, bei dem eine Personentragvorrichtung, in einem als Montagerahmen dienenden Gehäuse, mitten über einer Badewannenschmalseite, vertikal verschiebbar und horizontal schwenkbar geführt ist und durch eine Antriebsmaschine heb- und senkbar ist. Während das Gehäuse vorzugsweise auf der Badewannenschmalseite abgestützt und an der anliegenden Wand befestigt ist, kann es auch versenkt in die Wand eingebaut sein. Zur Verstärkung und Wandbefestigung des Gehäuses sind dessen Seiten durch Traversen miteinander verbunden. Zur Führung der Personentragvorrichtung ist im Gehäuse ein vertikales, unten offenes Vierkant-Führungsrohr befestigt und in ihm eine Vierkant-Tragstange verschiebbar gelagert, die an ihrem unteren Ende einen ersten horizontalen Tragarm in Wannenlängsrichtung und einen zweiten horizontalen Tragarm quer dazu aufweist. Der erste Tragarm trägt einen Schwenkbolzen, auf dem die Personentragvorrichtung horizontal schwenkbar gelagert ist, während der zweite Tragarm mit der Kolbenstange eines als Antriebsmittel dienenden hydraulisch betriebenen Arbeitszylinders verbunden ist, und so den vertikalen Antrieb der Vierkant-Tragstange bzw. der personentragvorrichtung gewährleistet. Der Arbeitszylinder ist am Vierkant-Führungsrohr sowie am Gehäuse abgestützt, wobei sich der Zylinder oben befindet und die Kolbenstange nach unten ausfahrbar ist. Zum Betrieb des Arbeitszylinders ist ein Motor-Pumpen-Aggregat vorgesehen. Im Betrieb dient der beschriebene Badelift dazu, eine z. B. als Sitz- und Liegeanordnung ausgebildete Personentragvorrichtung zwischen einer Stellung auf dem Wannenboden und einer Stellung senkrecht darüber maschinell zu verschieben, und sie über dem Wannenkörper, innerhalb dessen Breite, manuell auszuschwenken. Der Badewannenlift ist durch eine leicht zugängliche Betätigungsvorrichtung bedienbar, und er ermöglicht eine Überführung von Patienten in und aus Badewannen, sei es durch eine Pflegeperson oder in Selbstbedienung. Erste Nachteile dieser Lösung ergeben sich aus dem Umstande, dass Badewanne und Badewannenlift keine Einheit bilden und der Badelift z. B. nicht in den Gestellrahmen der Wanne integriert ist. Da in diesem Falle die Antriebsmaschine an einer Wand montiert ist, eignet sich ein solcher Badelift nicht für Badewannen, die aus therapeutischen oder ergonomischen Gründen rundherum frei zugänglich sein müssen. Auch kann eine damit ausgerüstete Badewanne nicht leicht und rasch an einem andern Ort aufgestellt werden, wenn sich dies aus baulichen oder betrieblichen Veränderungen als notwendig erweisen sollte. Weiter wird als Nachteil empfunden, dass die Personentragvorrichtung nicht seitlich über den Wannenkörper hinaus geschwenkt werden kann und sich insbesondere nicht ausserhalb der Badewanne absenken lässt. Dies kann den Transfer von Patienten von und zur Personentragvorrichtung beträchtlich erschweren.The aids available today for transferring handicapped persons of the type mentioned into and out of bathtubs have mainly been adopted from conventional lifting techniques and assembled into a piecework system that lacks a uniform concept. Thus, e.g. B. US Pat. No. 3,071,779 a bathtub with a bathtub lift, in which a person carrying device, in a housing serving as a mounting frame, is guided vertically displaceably and horizontally pivotably in the middle of a narrow bathtub side and can be raised and lowered by a drive machine. While the housing is preferably supported on the narrow side of the bathtub and fastened to the adjacent wall, it can also be built into the wall recessed. To reinforce and attach the housing to the wall, its sides are connected to each other by crossbars. To guide the person-carrying device, a vertical square guide tube open at the bottom is fastened and a square support rod is slidably mounted in it, which has a first horizontal support arm in the longitudinal direction of the tub and a second horizontal support arm transversely to it at its lower end. The first support arm carries a pivot pin on which the person support device is pivotally mounted horizontally, while the second support arm is connected to the piston rod of a hydraulically operated working cylinder serving as drive means, and thus ensures the vertical drive of the square support rod or the person support device. The working cylinder is supported on the square guide tube and the housing, with the cylinder at the top and the piston rod being extendable downwards. A motor-pump unit is provided for operating the working cylinder. In operation, the bath lift described serves a z. B. trained as a seat and lying arrangement of people carrying device between a position on the tub floor and a position vertically above it, and manually swing it over the tub body, within its width. The bathtub lift can be operated by an easily accessible actuation device, and it enables patients to be transferred into and out of bathtubs, whether by a caregiver or self-service. The first disadvantages of this solution result from the fact that bathtub and bathtub lift do not form a unit and the bath lift e.g. B. is not integrated in the frame of the tub. Since in this case the drive machine is mounted on a wall, such a bath lift is not suitable for bathtubs which must be freely accessible all around for therapeutic or ergonomic reasons. Also, a bathtub equipped with it cannot be easily and quickly installed in another location if this should prove necessary due to structural or operational changes. Another disadvantage is that the person-carrying device cannot be pivoted laterally beyond the body of the bathtub and, in particular, cannot be lowered outside the bathtub. This can make the transfer of patients from and to the personal support device considerably more difficult.

Weiter ist im US-Patent Nr. 3,078,473 ein Badewannenlift beschrieben, bei dem eine mit Wasser vom öffentlichen Netz betriebene Hydraulik verwendet wird. Offensichtlich ist ein solcher Antrieb von der lokalen Wasserversorgung und insbesondere von deren Wasserdruck abhängig. Auch sind Aufstellung und allenfalls notwendige Umstellungen bei einer solchen Badewanne nicht freizügig möglich, da auf den Wasseranschluss für die Hydraulik Rücksicht genommen werden muss. Weiter besteht auch bei dieser Badewanne die Erschwernis, dass die Personentragvorrichtung nicht ausserhalb des Wannenkörpers abgesenkt werden kann. Schliesslich ist aus dem französischen Patent Nr. 399969 eine Vorrichtung bekannt, mit der Patienten auf einer Liege in und aus Badewannen überführt werden können, wobei die Badewanne auf einem fahrbaren Gestellrahmen gelagert ist. Diese Vorrichtung ist veraltet und löst in keiner Weise die Probleme des Patiententransportes in der heutigen Alters- und Krankenpflege. Insbesondere entspricht sie nicht den Anforderungen wie sie im heutigen Badebetrieb an eine Patientenüberführvorrichtung gestellt werden. Hier will die Erfindung Abhilfe schaffen.Furthermore, a bathtub lift is described in US Pat. No. 3,078,473, in which a hydraulic system operated with water from the public network is used. Obviously, such a drive depends on the local water supply and in particular on its water pressure. Also, installation and any necessary changes in such a bathtub are not freely possible because the water connection for the hydraulics must be taken into account. Furthermore, this bathtub also has the difficulty that the person-carrying device cannot be lowered outside the body of the tub. Finally, a device is known from French Patent No. 399969, with which patients on a couch in and can be transferred from bathtubs, the bathtub being mounted on a mobile frame. This device is out of date and in no way solves the problems of patient transportation in today's old age and nursing care. In particular, it does not meet the requirements that are placed on a patient transfer device in today's bathing operation. The invention seeks to remedy this.

Im übrigen ist eine Spital-Badewanne mit elektrohydraulisch betriebener Hebevorrichtung, deren Personentragvorrichtung sich ausserhalb des Wannenkörpers absenken lässt, im US-Patent Nr. 3,371,357 dargestellt. Allerdings enthält auch dieses Patent keine Anregung, wie die Spital-Badewanne ortsbeweglich gestaltet werden könnte.In addition, a hospital bathtub with an electrohydraulically operated lifting device, the person-carrying device of which can be lowered outside the body of the bath, is shown in US Pat. No. 3,371,357. However, this patent does not contain any suggestion as to how the hospital bathtub could be designed to be portable.

Das Ziel der Erfindung ist, eine Spital-Badewanne zu schaffen, bei der die Wanne und das zugehörige Hebezeug als Einheit gestaltet sind und die Wanne selbst in herkömmlicher handelsüblicher Form gestaltet ist. Das Antriebsmittel des Hebezeuges soll nicht zu Verschmutzungen Anlass geben und das Hebezeug selbst soll als ein in die Wanneneinheit eingegliedertes Aggregat gestaltet sein. Weiterhin soll die Wanne auf ihrer Unterseite ausreichend Bodenfreiheit gewähren und im wesentlichen rundum frei zugänglich sein.The aim of the invention is to create a hospital bathtub in which the tub and the associated lifting equipment are designed as a unit and the tub itself is designed in a conventional, commercially available form. The drive means of the hoist should not give rise to soiling and the hoist itself should be designed as an aggregate integrated in the tub unit. Furthermore, the tub should provide sufficient ground clearance on its underside and be essentially freely accessible all around.

Die durch dieses Erfindungsziel gegebene Aufgabe wird durch eine Spital-Badewanne gelöst, deren kennzeichnende Merkmale aus dem Patentanspruch 1 hervorgehen. Ausführungsformen davon sind aus den abhängigen Ansprüchen herauslesbar.The object given by this object of the invention is achieved by a hospital bathtub, the characteristic features of which emerge from patent claim 1. Embodiments thereof can be read from the dependent claims.

Ein Ausführungsbeispiel des Erfindungsgegenstandes ist nachstehend anhand der Zeichnung beschrieben. In dieser zeigt

  • Figur 1 eine erfindungsgemäss gestaltete Badewanne in perspektivischer Darstellungsweise, teilweise geschnitten, mit vollständig ausgefahrener Sitzanordnung, und
  • Figur 2 eine Stirnseitenansicht auf das Hebeaggregat, wobei die Sitzanordnung in Aufnahme- und Bade-Position dargestellt ist.
An embodiment of the subject matter of the invention is described below with reference to the drawing. In this shows
  • 1 shows a bathtub designed according to the invention in a perspective representation, partially in section, with the seat arrangement fully extended, and
  • Figure 2 is an end view of the lifting unit, the seat arrangement being shown in the receiving and bathing positions.

Ein im Prinzip herkömmlicher Wannenkörper 1 für Freiaufstellung oder Einbauanordnung liegt mit einem umlaufenden Randflansch 2 auf den Holmen 3 eines allgemein mit 4 bezeichneten Gestellrahmens auf. Der Gestellrahmen 4 ist vorzugsweise eine Rohrkonstruktion, welche einen im wesentlichen durchgehend verbundenen Hohlraum 5 begrenzt. In einer der Gestellsecken, vorzugsweise benachbart eines elektrohydraulischen Aggregates 6 aus einem Elektromotor 6' und einer Pumpe 6" ist ein Hydraulikzylinder 7 angebaut, an dessen ausschiebbarer Kolbenstange 8 eine Tragkonstruktion 9 zur Aufnahme einer Stuhlschale 10 aufgesetzt ist. Unter den hier verwendeten Bezeichnungen Stuhlschale und Sitzanordnung sind selbstverständlich auch Stützmittel zu verstehen, durch die ein Patient in liegender Stellung aufgenommen werden kann.A basically conventional tub body 1 for free-standing installation or installation arrangement lies with a peripheral edge flange 2 on the bars 3 of a frame frame, generally designated 4. The frame 4 is preferably a tubular structure which delimits an essentially continuously connected cavity 5. In one of the frame corners, preferably adjacent to an electrohydraulic unit 6 comprising an electric motor 6 'and a pump 6 ", a hydraulic cylinder 7 is mounted, on the push-out piston rod 8 of which a supporting structure 9 for receiving a chair shell 10 is attached. Under the terms used here chair shell and Seat arrangements are of course also to be understood as supporting means by which a patient can be taken up in a lying position.

Fig. 2 zeigt die Sitzanordnung aus der Tragkonstruktion 9 und der Stuhlschale 10, welch' letztere zweckmässig aus einem formbeständigen wasserabweisenden Kunststoff gefertigt ist, mit ausgezogenem Strich in Aufnahmeposition für den Benützer, wobei die Sitzplatte 10' zweckmässig auf Rollstuhlsitzhöhe, d. h. etwa 45-50 cm über Boden abgesenkt ist. Durch Ausstossen der Kolbenstange 8 aus dem Hydraulikzylinder 7 auf eine Höhe wie etwa in Fig. 1 gezeigt, wo sich die Sitzplatte 10' samt dem darauf sitzenden Benützer ausreichend über dem Wannenrandflansch 2 befindet, ist die Sitzanordnung 9, 10 in eine etwa über der Längsmittenebene 11 der Wanne 1 liegende Stellung schwenkbar. Nach Absenken der Sitzanordnung durch entlasten des Kolbens 8 gelangt der Benützer, gemäss Darstellung mit unterbrochenem Strich, in eine Stellung innerhalb des Wannenkörpers 1, in welchem die vorgesehene Behandlung entweder direkt, oder nach Absetzen auf dem Wannenboden in einer für das Bedienungspersonal passenden Höhe stattfinden kann.Fig. 2 shows the seat arrangement of the support structure 9 and the chair shell 10, which 'the latter is expediently made of a dimensionally stable water-repellent plastic, with a drawn line in the receiving position for the user, the seat plate 10' expediently at the wheelchair seat height, d. H. is lowered about 45-50 cm above the floor. By ejecting the piston rod 8 from the hydraulic cylinder 7 to a height such as shown in FIG. 1, where the seat plate 10 'and the user sitting thereon are located sufficiently above the rim flange 2 of the seat, the seat arrangement 9, 10 is approximately at the longitudinal center plane 11 of the tub 1 lying position pivotable. After lowering the seat arrangement by relieving the piston 8, the user, as shown with a broken line, reaches a position within the tub body 1 in which the intended treatment can take place either directly or after being placed on the tub floor at a suitable height for the operating personnel .

Für die Betätigung der aus dem Hydraulikzylinder 7 und der Kolbenstange 8 bestehenden Hebevorrichtung wird gereinigtes, zweckmässig mit einem korrosionshemmenden Zusatz versehenes Wasser oder eine andere wässrige Flüssigkeit verwendet, die bei einem allfälligen Lecken der Hydraulikteile wie Wasser entfernt werden kann. Die Hydraulikflüssigkeit befindet sich in dem durch den Rohrrahmen 4 begrenzten Hohlraum 5 und wird der Pumpe 6" über eine Zuleitung 12 zugeführt. Eine Druckleitung 13 speist den Hydraulikzylinder 7 an. Wahlweise kann das den Oberteil des Hydraulikzylinders mit dem Rohr-Gestellrahmen 4 verbindende Bauteil 14 als Ueberlauf- bzw. Rückführleitung gestaltet werden, die sich auf der Höhe des unteren Kolbenstangenendes bei voll ausgefahrener Kolbenstange 8 befindet, um so den Aufwärtshub der Sitzanordnung 9, 10 automatisch zu begrenzen. Die vom Pumpaggregat 6 geförderte Hydraulikflüssigkeit fliesst dann unter der Kolbenfläche über die Ueberlauf- oder Rückführleitung 14 in den Hohlraum.5 des Gestellrahmens zurück.For the actuation of the lifting device consisting of the hydraulic cylinder 7 and the piston rod 8, purified water, appropriately provided with a corrosion-inhibiting additive, or another aqueous liquid is used, which can be removed in the event of any leakage of the hydraulic parts, such as water. The hydraulic fluid is located in the cavity 5 delimited by the tubular frame 4 and is fed to the pump 6 ″ via a feed line 12. A pressure line 13 feeds the hydraulic cylinder 7. The component 14 connecting the upper part of the hydraulic cylinder to the tubular frame 4 can optionally be used be designed as an overflow or return line which is located at the level of the lower end of the piston rod when the piston rod 8 is fully extended, so as to automatically limit the upward stroke of the seat arrangement 9, 10. The hydraulic fluid conveyed by the pump unit 6 then flows under the piston surface via the Overflow or return line 14 back into the Hohlraum.5 of the frame.

Als Pumpe 6" wird zweckmässig eine Flügelpumpe verwendet, die bei stillstehendem Antriebsmotor einen praktisch ungehemmten Rückfluss der Hydraulikflüssigkeit erlaubt. Es ist somit möglich, das Absenken der Sitzanordnung sowohl in die Badewanne als auch ausserhalb derselben durch einfaches Reduzieren der Drehzahl oder Abstellen des Antriebsmotors vorzunehmen. Wahlweise kann in die Druckleitung 13 eine Blendenvorrichtung 15 eingebaut werden, welche - fest oder verstellbar - sowohl die·Hebe- als auch die Senkgeschwindigkeit zu steuern gestattet. Wahlweise kann auch der Antriebsmotor drehzahlverstellbar sein, um die gewünschte Bewegungsgeschwindigkeit der Sitzanordnung zu steuern.As the pump 6 ", a vane pump is expediently used which, when the drive motor is at a standstill, allows a practically uninhibited backflow of the hydraulic fluid. It is thus possible to lower the seat arrangement both into the bathtub and outside of it by simply reducing the speed or switching off the drive motor. An orifice device 15 can be installed in the pressure line 13, which allows both fixed and adjustable control of both the lifting and lowering speed, and the drive motor can also be adjustable in speed in order to control the desired speed of movement of the seat arrangement.

Es versteht sich, dass die Pumpe 6" auch als rücklaufsperrendes Organ gestaltet sein kann, und der Rücklauf der Hebevorrichtung 7, 8 über eine (nicht gezeigte) separate steuerbare Rücklaufleitung mit einem Rücklaufventit erfolgen kann.It goes without saying that the pump 6 ″ can also be designed as a non-return element, and the return of the lifting device 7, 8 via a separate controllable return line (not shown) with a return valve can take place.
