Description

Die vorliegende Erfindung betrifft einen Adapter für eine Patiententrage, mit dem eine Obertrage und ein Inkubator auf einem Fahrgestell befestigt werden können.The present invention relates to an adapter for a patient stretcher, with which an upper stretcher and an incubator can be attached to a chassis.

Stand der TechnikState of the art

Heutzutage werden für den Transport von Patienten spezielle Patiententragen oder Krankentragen eingesetzt. Der Patient wird auf eine Obertrage gelegt und fixiert. Die Obertrage ist an einem Fahrgestell befestigt, mittels dem der Patient bewegt werden kann. Zudem verfügen solche Patiententragen meist über Mittel zum Verstellen der Höhe der Patiententrage, welche typischerweise in dem Fahrgestell verbaut sind. Es sind Patiententragen mit elektrischen Antrieb zum einen des Fahrgestells und zum anderen der Mittel zum Verstellen der Höhe bekannt, sodass ohne große Anstrengung einer Hilfsperson die Patiententrage mitsamt dem Patienten bewegt bzw. deren Höhe verstellt werden kann. Typischerweise sind die Patiententragen darüber hinaus eingerichtet, in einem Krankenwagen transportiert zu werden. Hierfür werden die Patiententragen in ein fest im Krankenwagen verbautes Tragegestell eingeschoben, wobei das Fahrgestell einklappbar ausgestaltet ist. Sobald die Patiententrage an dem Tragegestell anliegt, klappt das Fahrgestell ein und die Patiententrage liegt auf dem Tragegestell auf und kann auf diesem verfahren werden.Nowadays, special patient carriers or stretchers are used for the transport of patients. The patient is placed on a stretcher and fixed. The upper stretcher is attached to a chassis by means of which the patient can be moved. In addition, such patient carriers usually have means for adjusting the height of the patient carrier, which are typically installed in the chassis. There are known patient stretches with an electric drive on the one hand of the chassis and on the other hand of the means for adjusting the height, so that the patient stretcher together with the patient can be moved or the height thereof adjusted without great effort by an auxiliary person. Typically, the patient carriers are also set up to be transported in an ambulance. For this purpose, the patient stretches are pushed into a support frame that is permanently installed in the ambulance, the chassis being designed to be foldable. As soon as the patient carrier lies against the carrier frame, the chassis folds in and the patient carrier lies on the carrier frame and can be moved on it.

Des Weiteren werden heutzutage Inkubatoren zum Transport und zur Erstversorgung von Neugeborenen und Kleinkindern eingesetzt. Im Normalfall weist ein Krankenwagen keine fest installierten Inkubatoren auf. Vielmehr wird ein Inkubator bei Bedarf, zum Beispiel von einem Krankenhaus, bereitgestellt. Der Inkubator muss dann entweder von Hand in den Krankenwagen getragen werden oder mit einem Fahrgestell transportiert werden. Inkubatoren sind oftmals auf Inkubatorgestellen befestigt, die zum Transport des Inkubators von Hand dienen und meist seitliche Handgriffe sowie Transportrollen an der Unterseite aufweisen.Furthermore, today incubators are used for the transport and primary care of newborns and toddlers. Usually, an ambulance has no permanently installed incubators. Rather, an incubator is provided as needed, for example from a hospital. The incubator must then either be carried by hand into the ambulance or transported on a chassis. Incubators are often attached to incubator racks that are used to transport the incubator by hand serve and usually have side handles and transport rollers on the underside.

Aus der DE 37 19 781 C1 ist ein Fahrgestell zum Transport eines Inkubators oder einer Krankenliege, d. h. einer Obertrage, bekannt. Das Fahrgestell besteht im Wesentlichen aus Längsholmen, Querholmen, welche ein Gestänge bilden, und Stützenpaaren sowie Längsstangen und Stützenstangen, die zur Verstärkung dienen. Bei Verwendung der Obertrage wird diese direkt mit den Längsholmen des Fahrgestells verbunden. Hierzu können nicht näher beschriebene Befestigungsmittel zur Befestigung an den Längsholmen verwendet werden. Um den Inkubator auf dem Fahrgestell zu befestigen, ist eine Aufstellplatte vorgeschlagen. Auf der Aufstellplatte sind Gabelfallen-Schlösser angeordnet, in welche Bolzen des Inkubators eingreifen und den Inkubator somit befestigen. Die Aufstellplatte selbst ist wiederum mit den Längsholmen des Fahrgestells verbunden. Da sowohl die Obertrage als auch die Aufstellplatte an den Längsholmen befestigt sind, ist eine einfache Austausch der Obertrage mit dem Inkubator oder umgekehrt nicht möglich. Um den Inkubator mit der Obertrage zu tauschen, muss die Aufstellplatte ausgebaut werden und die Obertrage mit dem Befestigungsmitteln an den Längsholmen befestigt werden, was einen zusätzlichen Aufwand darstellt.From the DE 37 19 781 C1 is known a chassis for transporting an incubator or a patient bed, ie an upper stretcher. The chassis essentially consists of longitudinal spars, transverse spars, which form a linkage, and pairs of supports, as well as longitudinal rods and support rods, which serve for reinforcement. When using the upper stretcher, it is connected directly to the longitudinal rails of the chassis. Fasteners (not described in more detail) for fastening to the longitudinal spars can be used for this purpose. In order to attach the incubator to the chassis, a stand plate is proposed. Fork latch locks are arranged on the mounting plate, into which bolts of the incubator engage and thus fasten the incubator. The platform itself is in turn connected to the longitudinal spars of the chassis. Since both the upper stretcher and the support plate are attached to the longitudinal spars, it is not possible to simply replace the upper stretcher with the incubator or vice versa. In order to exchange the incubator with the upper stretcher, the base plate must be removed and the upper stretcher fastened to the longitudinal spars with the fastening means, which represents an additional outlay.

Die US 5,490,703 A beschreibt ein System zum Überführen von Patienten in und aus einem Rettungsfahrzeug und zum Sichern der Patienten während des Transports. Es ist eine Schale vorgesehen, die als Adapter für die Befestigung an einer Hubschlitten dient und eine Obertrage aufnehmen kann. Hierfür weist die Schale an ihrer Oberseite Haltelemente, die in das Gestänge der Obertrage eingreifen, und einen Schlosskasten zur Verriegelung der Obertrage auf. Ferner weist der Adapter an der Seite einen Verriegelungsstift auf, der als Befestigungselement für einen Inkubator dienen kann.The US 5,490,703 A describes a system for transferring patients into and out of an ambulance and for securing the patients during transport. A shell is provided which serves as an adapter for attachment to a lifting slide and can accommodate an upper stretcher. For this purpose, the shell has holding elements on its upper side which engage in the linkage of the upper stretcher and a lock case for locking the upper stretcher. Furthermore, the adapter has a locking pin on the side, which can serve as a fastening element for an incubator.

Der Adapter weist einen wannenförmigen Grundkörper auf. Der Grundkörper weist eine im Wesentlichen rechteckige Bodenfläche auf, an deren Kanten ein Rand nach oben hin ausgebildet ist, der vorzugsweise einstückig mit der Bodenplatte ausgebildet ist und beispielsweise durch Biegen entsteht. Vorzugsweise besteht der Grundkörper aus Metall, vorzugsweise in Form eines Blechs. Der wannenförmige Grundkörper bietet im Vergleich zu einer einfachen Platte den Vorteil, dass der Adapter deutlich verwindungssteifer ist. Zudem können vergleichsweise mehr Kräfte aufgenommen werden, weswegen sich der Grundkörper bei einem Zusammenstoß Unfall deutlich weniger verformt. Darüber hinaus können am Rand zusätzliche Halterungen angebracht werden, an denen z. B. Korbschleiftragen befestigt werden können, die beispielsweise in Katastrophenfällen oder bei einer Bergrettung zum Einsatz kommen.The adapter has a trough-shaped base body. The base body has a substantially rectangular bottom surface, at the edges of which Edge is formed upwards, which is preferably formed in one piece with the base plate and is formed for example by bending. The base body preferably consists of metal, preferably in the form of a sheet. The trough-shaped body offers the advantage over a simple plate that the adapter is significantly more torsion-resistant. In addition, comparatively more forces can be absorbed, which is why the base body deforms significantly less in the event of a collision. In addition, additional brackets can be attached to the z. B. basket sanding straps can be attached, which are used for example in disasters or in a mountain rescue.

Der Grundkörper ist vorteilhafterweise über die Bodenfläche mit dem Fahrgestell der Patiententrage verbunden. Alternativ kann der Grundkörper auch über den Rand mit dem Fahrgestell verbunden sein. In beiden Fällen kann der Grundkörper einerseits fest mit dem Fahrgestell verbunden sein, beispielsweise durch Schweißen oder Nieten, oder lösbar mittels Befestigungsmitteln, wie z. B. Schrauben, mit dem Fahrgestell verbunden sein. Rein prinzipiell kann der Grundkörper mit jedem Teil des Fahrgestells verbunden werden, bevorzugt ist der Grundkörper allerdings mit dem zur Aufnahme des Transportguts vorgesehenen Gestänge des Fahrgestells verbunden. Diese Verbindung zwischen dem Grundkörper des Adapters und dem Fahrgestell muss beim Austausch der Obertrage mit dem Inkubatoraufsatz bzw. dem Inkubatorgestell oder umgekehrt nicht gelöst werden.The base body is advantageously connected to the chassis of the patient carrier via the floor surface. Alternatively, the base body can also be connected to the chassis via the edge. In both cases, the base body can be firmly connected to the chassis on the one hand, for example by welding or riveting, or releasably by means of fasteners, such as. B. screws, connected to the chassis. In principle, the base body can be connected to any part of the chassis, but the base body is preferably connected to the linkage of the chassis provided for receiving the goods to be transported. This connection between the base body of the adapter and the chassis does not have to be released when replacing the upper stretcher with the incubator attachment or the incubator frame or vice versa.

Ausgehend vom Grundkörper lassen sich Richtungen, Achsen und Seiten definieren. Als Kopfseite wird die Seite des Grundkörpers betrachtet, in der bei Aufnahme der Obertrage im Normalfall der Kopf des Patienten liegt. Analog wird als Fußseite die Seite des Grundkörpers betrachtet, in der bei Aufnahme der Obertrage im Normalfall die Füße des Patienten liegen. Die zum Fahrgestell hin zeigende Seite wird als Unterseite bezeichnet, die gegenüberliegende vom Fahrgestell abgewandte Seite wird als Oberseite bezeichnet.Starting from the basic body, directions, axes and sides can be defined. The side of the base body is considered as the head side, in which the patient's head normally lies when the upper stretcher is picked up. Analogously, the side of the base body is considered as the foot side, in which the patient's feet normally lie when the upper stretcher is taken up. The side facing the chassis is referred to as the underside, the opposite side facing away from the chassis is referred to as the top.

Auf dem Grundkörper, genauer auf der Bodenfläche des Grundkörpers, sind auf der Oberseite zumindest ein Befestigungselement, zumindest ein Halteelement und ein Schlosskasten befestigt. Die Befestigung kann rein prinzipiell fest sein, beispielsweise durch Schweißen oder Nieten, bevorzugt aber lösbar sein und mittels Befestigungsmitteln, wie z. B. Schrauben, realisiert werden. Es ist vorgesehen ist, dass die Befestigung des zumindest einen Befestigungselements mit dem Grundkörper beim Austausch der Obertrage mit dem Inkubatoraufsatz bzw. dem Inkubatorgestell oder umgekehrt nicht gelöst werden muss. Die genannten Elemente sind in der Praxis nach der Montage und insbesondere bei der Verwendung der Trage allesamt gleichzeitig auf dem Grundkörper befestigt und werden insbesondere nur zur Wartung und gegebenenfalls zur Reinigung gelöst.At least one fastening element, at least one holding element and a lock case are fastened on the top of the base body, more precisely on the base surface of the base body. In principle, the fastening can be fixed, for example by welding or riveting, but preferably it can be detached and by means of fastening means, such as, for. B. screws can be realized. It is it is provided that the fastening of the at least one fastening element to the base body does not have to be released when the upper stretcher is exchanged with the incubator attachment or the incubator frame or vice versa. In practice, the elements mentioned are all attached to the base body at the same time after assembly and in particular when the stretcher is used, and in particular are only loosened for maintenance and possibly for cleaning.

Das zumindest eine Befestigungselement ist eingerichtet, ein Verbindungselement, beispielsweise einen Bolzen, eines Inkubatoraufsatzes oder eines Inkubatorgestells aufzunehmen und zu sichern. Der zu transportierende Inkubator kann demnach als Inkubatoraufsatz, welcher das Verbindungselement aufweist, direkt auf dem wannenförmigen Grundkörper befestigt werden oder zuerst auf einem Inkubatorgestell befestigt werden, welches das Verbindungselement aufweist und auf dem wannenförmigen Grundkörper befestigt wird. Wie später detailliert beschrieben ist die Verbindung zwischen dem zumindest einen Befestigungselement und dem Inkubatoraufsatz bzw. dem Inkubatorgestell sicher und zudem auf einfache Weise lösbar, vorzugsweise von Hand lösbar.The at least one fastening element is designed to receive and secure a connecting element, for example a bolt, an incubator attachment or an incubator frame. The incubator to be transported can therefore be attached as an incubator attachment, which has the connecting element, directly to the trough-shaped base body or first attached to an incubator frame, which has the connecting element and is attached to the trough-shaped base body. As described in detail later, the connection between the at least one fastening element and the incubator attachment or the incubator frame is secure and, moreover, detachable in a simple manner, preferably detachable by hand.

Das zumindest eine Halteelement und der Schlosskasten sind eingerichtet, die Obertrage aufzunehmen. Das zumindest eine Halteelement ist dabei eingerichtet, eine Gestellstange der Obertrage zu halten. Die Gestellstange kann hierbei eine Stange sein, die zum Grundgerüst der Obertrage gehört oder extra ausgebildet ist, insbesondere eine speziell zur Halterung ausgebildete Stange, oder Teil einer Achse der Obertrage sein. Der Schlosskasten ist in einer an sich bekannten Form eingerichtet, ein Verriegelungselement der Obertrage aufzunehmen und zu sichern. Hierzu weist der Schlosskasten ein Verriegelungssystem auf, welches für die Sicherung des Verriegelungselements der Obertrage angepasst ist. Die Obertrage kann auf dem Grundkörper, genauer auf der Bodenfläche, in den Adapter eingeschoben werden, sodass die Gestellstange von dem Halteelement gehalten wird. Dann tritt das Verriegelungselement in den Schlosskasten ein und wird durch das Verriegelungssystem gesichert. Der Schlosskasten weist bevorzugt einen Hebel auf, mit dem das Verriegelungssystem von Hand wieder gelöst werden kann und die Obertrage entlassen werden kann. Damit wird eine sichere Befestigung der Obertrage realisiert, die auf einfache Weise wieder gelöst werden kann.The at least one holding element and the lock case are set up to accommodate the upper stretcher. The at least one holding element is designed to hold a frame rod of the upper stretcher. The frame rod can be a rod that belongs to the basic structure of the upper stretcher or is specially designed, in particular a rod specially designed for holding, or part of an axis of the upper stretcher. The lock case is designed in a manner known per se to accommodate and secure a locking element of the upper stretcher. For this purpose, the lock case has a locking system which is adapted for securing the locking element of the upper stretcher. The upper stretcher can be pushed into the adapter on the base body, more precisely on the bottom surface, so that the frame rod is held by the holding element. Then the locking element enters the lock case and is secured by the locking system. The lock case preferably has a lever with which the locking system can be released again by hand and the upper stretcher can be released. This ensures a secure attachment of the upper stretcher, which can be easily removed again.

Der vorstehend beschriebene Adapter weist daher gleichzeitig Elemente auf, mit denen zum einen die Obertrage am Fahrgestell befestigt werden kann und zum anderen der Inkubatoraufsatz bzw. das Inkubatorgestell am Fahrgestell befestigt werden kann. Der Austausch der Obertrage mit dem Inkubatoraufsatz bzw. dem Inkubatorgestell und/oder umgekehrt kann in einfacher und schneller Weise, insbesondere von Hand erfolgen, da das zumindest eine Befestigungselement und der Schlosskasten, wie beschrieben, vorzugsweise von Hand betätigt werden können. Um die Obertrage mit dem Inkubatoraufsatz bzw. dem Inkubatorgestell oder umgekehrt auszutauschen, muss weder das zumindest eine Befestigungselement noch das zumindest eine Halteelement oder der Schlosskasten vom Grundkörper gelöst werden. Ebenso wenig muss hierfür der Adapter an sich vom Fahrgestell gelöst werden.The adapter described above therefore has elements at the same time with which the upper stretcher can be attached to the chassis and the incubator attachment or the incubator frame can be attached to the chassis. The exchange of the upper stretcher with the incubator attachment or the incubator frame and / or vice versa can be carried out in a simple and quick manner, in particular by hand, since the at least one fastening element and the lock case, as described, can preferably be actuated by hand. In order to replace the upper stretcher with the incubator attachment or the incubator frame or vice versa, neither the at least one fastening element nor the at least one holding element or the lock case has to be detached from the base body. Neither does the adapter itself have to be detached from the chassis for this.

Gemäß einem Aspekt ist der wannenförmige Grundkörper an den Verbindungsstellen, an denen das zumindest eine Befestigungselement, das zumindest eine Halteelemente und/oder der Schlosskasten am Grundkörper befestigt sind, mit Verstärkungselementen verstärkt. Die Verstärkungselemente sind beispielsweise Platten, welche an den Verbindungstellen auf der Unterseite der Bodenfläche an dieser befestigt sind. Bevorzugt sind die Verstärkungselemente auf die gleiche Weise und besonders bevorzugt mittels denselben Befestigungsmitteln wie das zumindest eine Befestigungselement, das zumindest eine Haltelement und/oder der Schlosskasten an der Bodenfläche befestigt. Vorteilhafterweise decken die Verstärkungselemente die gleiche Fläche wie das zumindest eine Befestigungselement, das zumindest eine Haltelement und/oder der Schlosskasten ab.According to one aspect, the trough-shaped base body is reinforced with reinforcing elements at the connection points at which the at least one fastening element, the at least one holding element and / or the lock case are fastened to the base body. The reinforcement elements are, for example, plates which are fastened to the connection points on the underside of the base surface. The reinforcing elements are preferably in the same way and particularly preferably by means of the same fastening means as the at least one fastening element which fastens at least one holding element and / or the lock case to the bottom surface. The reinforcing elements advantageously cover the same area as the at least one fastening element, the at least one holding element and / or the lock case.

Das zumindest eine Befestigungselement ist als Befestigungsschuh ausgebildet, der eine Öffnung aufweist, in die ein bolzenförmiges Verbindungselement des Inkubatoraufsatzes oder des Inkubatorgestells eingeführt werden kann, sodass der Befestigungsschuh das bolzenförmige Verbindungselement aufnehmen kann. Typische bolzenförmige Verbindungselemente eines Inkubatoraufsatzes oder eines Inkubatorgestells weisen eine Einbuchtung entlang des Umfangs auf. Vorzugsweise kann der Befestigungsschuh eine innenlaufende Nut aufweisen, der beim Einschieben des bolzenförmigen Verbindungselements während dem Befestigen des Inkubatoraufsatzes oder des Inkubatorgestells in die Einbuchtung des bolzenförmigen Verbindungselements eingreift. Somit wird ein Herausrutschen des bolzenförmigen Verbindungselements nach oben hin verhindert Zudem ist ein Sicherungselement vorgesehen, welches eingerichtet ist, das bolzenförmige Verbindungselement im aufgenommenen Zustand zu sichern.The at least one fastening element is designed as a fastening shoe which has an opening into which a bolt-shaped connecting element of the incubator attachment or of the incubator frame can be inserted, so that the fastening shoe can receive the bolt-shaped connecting element. Typical bolt-shaped connecting elements of an incubator attachment or an incubator frame have an indentation along the circumference. Preferably, the fastening shoe can have an internal groove which, when the bolt-shaped connecting element is inserted during the fastening of the incubator attachment or the incubator frame, into the indentation of the engages bolt-shaped connecting element. This prevents the bolt-shaped connecting element from slipping out toward the top. In addition, a securing element is provided, which is designed to secure the bolt-shaped connecting element in the received state.

Gemäß einem Aspekt ist das zumindest eine Halteelement U-förmig ausgestaltet, wobei durch die U-Form eine Öffnung gebildet wird. In diese Öffnung ist die Gestellstange der Obertrage einschiebbar. Ist die Gestellstange in die Öffnung eingeschoben, umschließt das zumindest eine U-förmige Halteelement die Gestellstange teilweise mit den übrigen Seiten.According to one aspect, the at least one holding element is U-shaped, an opening being formed by the U-shape. The frame rod of the upper stretcher can be inserted into this opening. If the frame rod is pushed into the opening, the at least one U-shaped holding element partially surrounds the frame rod with the other sides.

Vorteilhafterweise zeigen die Öffnung des zumindest einen Befestigungsschuhs, die Öffnung des zumindest einen U-förmigen Halteelements und die Öffnung des Schlosskasten in eine gemeinsame Richtung, vorzugsweise zum fußseitigen Ende des Grundkörpers hin. Auf diese Weise können sowohl die Obertrage als auch der Inkubatoraufsatz oder das Inkubatorgestell von der gleichen Richtung her in den Adapter eingeschoben werden.The opening of the at least one fastening shoe, the opening of the at least one U-shaped holding element and the opening of the lock case advantageously point in a common direction, preferably towards the foot-side end of the base body. In this way, both the upper stretcher and the incubator attachment or the incubator frame can be inserted into the adapter from the same direction.

Die bevorzugte Form des Sicherungselements für den Befestigungsschuh ist eine Verschlussstange. Der Befestigungsschuh weist in diesem Fall an ihrer Seiten eine Bohrung auf, in welche die Verschlussstange einschiebbar ist. Die Bohrung ist vorzugsweise so angeordnet, dass die Verschlussstange das bolzenförmige Verbindungselement in Richtung der Öffnung begrenzt. Zudem kann eine zweite Bohrung auf der gegenüberliegenden Seite angeordnet sein, durch welche die Verschlussstange aus dem Befestigungsschuh herausgeführt wird. Zudem kann die Verschlussstange in diesem Fall von beiden Seiten eingeschoben werden. In eingeschobenen Zustand sichert die Verschlussstange das bolzenförmige Verbindungselement, sodass sich das bolzenförmige Verbindungselement im Befestigungsschuh nicht mehr bewegen kann und insbesondere nicht aus diesem herausrutschen kann. Ist das bolzenförmige Verbindungselement in dem Befestigungsschuh aufgenommen, kann die Verschlussstange senkrecht zur Öffnung eingeschoben werden, auf der Seite der Öffnung dicht an dem bolzenförmigen Verbindungselement vorbei geführt werden und in die oben beschriebene Einbuchtung des bolzenförmigen Verbindungselements eingreifen. Somit wird ein Herausrutschen des bolzenförmigen Verbindungselements in Richtung der Öffnung und nach oben hin verhindert.The preferred form of the securing element for the fastening shoe is a locking rod. In this case, the fastening shoe has a bore on its side into which the locking rod can be inserted. The bore is preferably arranged so that the locking rod delimits the bolt-shaped connecting element in the direction of the opening. In addition, a second hole can be arranged on the opposite side, through which the locking rod is guided out of the fastening shoe. In this case, the locking rod can also be inserted from both sides. In the inserted state, the locking rod secures the bolt-shaped connecting element, so that the bolt-shaped connecting element can no longer move in the fastening shoe and in particular cannot slide out of it. If the bolt-shaped connecting element is received in the fastening shoe, the locking rod can be inserted perpendicular to the opening, can be guided past the bolt-shaped connecting element on the side of the opening and can engage in the indentation of the bolt-shaped connecting element described above. This prevents the bolt-shaped connecting element from slipping out in the direction of the opening and upwards.

Eine vorteilhafte Anordnung der Befestigungselemente auf dem Grundkörper sieht vor, dass zumindest zwei Befestigungselemente entlang einer Achse senkrecht zur Längsachse angeordnet sind. Die Bohrungen an den zumindest zwei Befestigungselementen sind derart ausgebildet, dass die Verschlussstange in zumindest zwei Befestigungselemente einschiebbar ist. Demnach weisen alle Befestigungselemente zwei Bohrungen auf. Das Befestigungselement, das am nächsten zur Kante des Grundkörpers angeordnet ist, kann rein prinzipiell auch nur eine Bohrung auf der zur Kante hinzeigenden Seite aufweisen, allerdings weist vorzugsweise auch dieses Befestigungselement zwei Bohrungen auf, sodass die Verschlussstange von beiden Seiten eingeführt werden kann. Alle Bohrungen sind entlang einer gemeinsamen Achse und auf gleicher Höhe angeordnet.An advantageous arrangement of the fastening elements on the base body provides that at least two fastening elements are arranged along an axis perpendicular to the longitudinal axis. The bores on the at least two fastening elements are designed such that the locking rod can be inserted into at least two fastening elements. Accordingly, all fasteners have two holes. The fastening element, which is arranged closest to the edge of the base body, can in principle also have only one hole on the side pointing towards the edge, but this fastening element preferably also has two holes, so that the locking rod can be inserted from both sides. All holes are arranged along a common axis and at the same height.

Optional kann die Bohrung des zumindest einen Befestigungselements derart ausgebildet sein und insbesondere auf solch einer Höhe angeordnet sein, dass die Verschlussstange über dem Rand des wannenförmigen Grundkörpers liegt. Mit anderen Worten ist die Bohrung des zumindest einen Befestigungselements oberhalb einer Ebene, die von den Oberkanten der Ränder gebildet wird, angeordnet. Dies bietet den Vorteil, dass ein Bediener die Verschlussstange bewegen kann, ohne unter den Inkubatoraufsatz bzw. das Inkubatorgestell zu greifen. Bevorzugt ist an einem Ende der Verschlussstange, das nicht in die Befestigungselemente eingeschoben wird und an dem der Bediener die Verschlussstange bewegt, ein Knauf vorgesehen. Der Knauf ist bevorzugt so ausgestaltet, dass seine Abmessungen in der Radialebene der Verschlussstange größer sind als der Abstand zwischen dem Rand des wannenförmigen Grundkörpers und der dem Rand zugewandten Seite der Verschlussstange. Dadurch wird verhindert, dass die Stange zu weit nach innen geschoben wird und der Bediener dabei unter den Inkubatoraufsatz bzw. das Inkubatorgestell muss.Optionally, the bore of the at least one fastening element can be designed and in particular arranged at such a height that the locking rod lies over the edge of the trough-shaped base body. In other words, the bore of the at least one fastening element is arranged above a plane which is formed by the upper edges of the edges. This offers the advantage that an operator can move the locking rod without reaching under the incubator attachment or the incubator frame. A knob is preferably provided on one end of the locking rod, which is not inserted into the fastening elements and on which the operator moves the locking rod. The knob is preferably designed such that its dimensions in the radial plane of the locking rod are greater than the distance between the edge of the trough-shaped base body and the side of the locking rod facing the edge. This prevents the rod from being pushed too far inwards and the operator has to go under the incubator attachment or the incubator frame.

Eine bevorzugte Anordnung der Elemente sieht wie folgt aus: Vier Befestigungselemente sind auf dem Grundkörper verteilt. Dabei sind die vier Befestigungselemente in je zwei Befestigungselemente aufgeteilt, die jeweils auf einer Achse senkrecht zur Längsachse liegen. Zwei der Befestigungselemente liegen auf einer Achse, die von der Mitte des Grundkörpers aus gesehen in Richtung des kopfseitigen Endes angeordnet sind, zwei weitere Befestigungselemente liegen auf einer Achse, die von der Mitte des Grundkörpers aus gesehen in Richtung des fußseitigen Endes angeordnet sind. Die genaue Position der Befestigungselemente und der Abstand zwischen diesen werden abhängig von dem Inkubatoraufsatz bzw. dem Inkubatorgestells und der genauen Position der Verbindungselemente des Inkubatoraufsatzes bzw. des Inkubatorgestells gewählt. Außerdem sind zwei der Haltelemente auf einer Mittelachse senkrecht und mittig zur Längsachse des wannenförmigen Grundkörpers angeordnet. Optional ist zumindest ein weiteres Haltelement auf einer Achse senkrecht zur Längsachse zwischen der Mittelachse und dem kopfseitigen Ende angeordnet. Schließlich ist der Schlosskasten zwischen der Mittelachse und dem fußseitigen Ende angeordnet. Die Position der Halteelemente wird abhängig von der Obertrage und von der Position und dem Abstand der Gestellstangen gewählt. Die Position des Schlosskastens wird abhängig von der Obertrage und von der Position des Verriegelungselements, insbesondere in Relation zu den Gestellstangen gewählt.A preferred arrangement of the elements is as follows: four fastening elements are distributed on the base body. The four fastening elements are each divided into two fastening elements, each of which lies on an axis perpendicular to the longitudinal axis. Two of the fastening elements lie on an axis, which, viewed from the center of the base body, are arranged in the direction of the head-side end, two more Fastening elements lie on an axis which, viewed from the center of the base body, are arranged in the direction of the foot-side end. The exact position of the fastening elements and the distance between them are selected depending on the incubator attachment or the incubator frame and the exact position of the connecting elements of the incubator attachment or the incubator frame. In addition, two of the holding elements are arranged on a central axis perpendicularly and centrally to the longitudinal axis of the trough-shaped base body. Optionally, at least one further holding element is arranged on an axis perpendicular to the longitudinal axis between the central axis and the head end. Finally, the lock case is arranged between the central axis and the foot end. The position of the holding elements is selected depending on the top stretcher and on the position and distance of the frame rods. The position of the lock case is selected depending on the top stretcher and on the position of the locking element, in particular in relation to the frame rods.

Ausführungsbeispiele der ErfindungEmbodiments of the invention

Figur 1 zeigt in einer isometrischen Darstellung den erfindungsgemäßen Adapter für eine nicht dargestellte Patiententrage gemäß einer Ausführungsform. Der Adapter weist einen wannenförmigen Grundköper 10 auf, der eine rechteckige Bodenfläche 11 umfasst, von der ein Rand 12 nach oben hin abgebogen ist und von der Bodenfläche 11 nach oben hervorragt. Der Grundkörper 10 ist über seine Bodenfläche 11 mit einem hier nicht dargestellten Fahrgestell der Patiententrage verbunden. Es ist eine Längsachse AL des Grundkörpers 10, die parallel zur längeren Kante durch die Mitte des Grundkörpers 10 auf der Bodenfläche 11 verläuft, und eine Mittelachse AM des Grundkörpers 10, die senkrecht zur Längsachse AL durch die Mitte des Grundkörpers 10 auf der Bodenfläche 11 verläuft, dargestellt. Zudem ist ein kopfseitiges Ende K und ein fußseitiges Ende F des Grundkörpers 10 definiert. Figure 1 shows in an isometric view the adapter according to the invention for a patient carrier, not shown, according to one embodiment. The Adapter has a trough-shaped base body 10, which comprises a rectangular base surface 11, from which an edge 12 is bent upwards and protrudes upwards from the base surface 11. The base body 10 is connected via its base surface 11 to a chassis of the patient carrier, not shown here. It is a longitudinal axis A L of the base body 10, which runs parallel to the longer edge through the center of the base body 10 on the bottom surface 11, and a central axis A M of the base body 10, which is perpendicular to the longitudinal axis A L through the center of the base body 10 on the Bottom surface 11 runs, shown. In addition, a head-side end K and a foot-side end F of the base body 10 are defined.

Der Adapter weist insgesamt vier Befestigungsschuhe 20, 20' auf, die entlang zweier Achsen A1, A2, die jeweils senkrecht zur Längsachse AL des Grundkörpers 10 stehen, angeordnet sind. Zwei der Befestigungsschuhe 20 sind auf einer ersten Achse A1 zwischen der Mittelachse AM des Grundkörpers 10 und dem kopfseitigen Endes K angeordnet und zwei weitere Befestigungsschuhe 20' sind auf einer zweiten Achse A2 zwischen der Mittelachse AM des Grundkörpers 10 und dem fußseitigen Ende f angeordnet. Die Befestigungsschuhe 20, 20' dienen zur Aufnahme und Sicherung von Bolzen eines Inkubatoraufsatzes oder eines Inkubatorgestells (hier nicht dargestellt). Exemplarisch ist eine Verschlussstange 21 dargestellt, die in zwei der Befestigungsschuhe 20 eingeschoben ist. Die Verschlussstange 21 dient als Sicherungselement für die Befestigungsschuhe und verhindert ein Herausrutschen des Bolzens des Inkubatoraufsatzes bzw. des Inkubatorgestells. Anders als hier dargestellt, wird die Verschlussstange 22 erst in die Befestigungsschuhe 20 eingeschoben, wenn die Bolzen des Inkubatoraufsatzes bzw. des Inkubatorgestells bereits in die Befestigungsschuhe 20 aufgenommen wurden. Die genaue Position der vier Befestigungsschuhe 20, 20' und der Abstand dazwischen ist abhängig vom Inkubatoraufsatz bzw. vom Inkubatorgestell, welches aufgenommen werden soll, und der Position der Bolzen dieses Inkubatoraufsatzes bzw. dieses Inkubatorgestells gewählt. Eine detailliertere Beschreibung der Befestigungsschuhe 20, 20' wird in Zusammenhang mit Figur 3 gegeben.The adapter has a total of four fastening shoes 20, 20 ', which are arranged along two axes A 1 , A 2 , which are each perpendicular to the longitudinal axis A L of the base body 10. Two of the fastening shoes 20 are arranged on a first axis A 1 between the central axis A M of the base body 10 and the head-side end K and two further fastening shoes 20 'are on a second axis A 2 between the central axis A M of the base body 10 and the foot-side end f arranged. The fastening shoes 20, 20 'serve to receive and secure bolts of an incubator attachment or an incubator frame (not shown here). A locking rod 21 is shown as an example, which is inserted into two of the fastening shoes 20. The locking rod 21 serves as a securing element for the fastening shoes and prevents the bolt of the incubator attachment or the incubator frame from slipping out. Unlike shown here, the locking rod 22 is only inserted into the fastening shoes 20 when the bolts of the incubator attachment or of the incubator frame have already been received in the fastening shoes 20. The exact position of the four fastening shoes 20, 20 'and the distance between them is dependent on the incubator attachment or on the incubator frame which is to be received and the position of the bolts of this incubator attachment or this incubator frame. A more detailed description of the mounting shoes 20, 20 'is provided in connection with Figure 3 given.

Gleichzeitig weist der Adapter insgesamt 3 Halteelemente 30, 30' auf. Zwei der Halteelemente 30 sind auf der Mittelachse AM angeordnet. Ein weiteres Halteelement 30' ist auf einer dritten Achse A3 nahe dem kopfseitigen Ende K, d. h. zwischen der ersten Achse A1 und dem kopfseitigen Ende K, angeordnet. In weiteren Ausführungsformen kann auf dieses weitere Halteelement 30' auf der dritten Achse A3 verzichtet werden. Die Halteelemente 30 sind eingerichtet, eine Gestellstange einer Obertrage (hier nicht dargestellt) zu halten. Wird die Obertrage auf der Bodenfläche 11 in den Adapter eingeschoben, halten die auf der Mittelachse AM angeordneten Halteelemente 30 beispielsweise eine Gestellstange, die an der Obertrage bereits zur Halterung ausgebildet ist und das am kopfseitigen Ende K angeordnete Haltelement 30' eine Achsenstange der Obertrage. Die Position der Haltelemente 30, 30' wird abhängig von der Obertrage, welche aufgenommen werden soll, und der Position und dem Abstand der Gestellstangen gewählt.At the same time, the adapter has a total of 3 holding elements 30, 30 '. Two of the holding elements 30 are arranged on the central axis A M. Another holding element 30 'is arranged on a third axis A 3 near the head-side end K, ie between the first axis A 1 and the head-side end K. In further embodiments, this further holding element 30 'on the third axis A 3 can be dispensed with. The holding elements 30 are set up to hold a frame rod of an upper stretcher (not shown here). If the upper stretcher is pushed into the adapter on the bottom surface 11, the holding elements 30 arranged on the central axis A M hold, for example, a frame rod which is already designed for holding on the upper stretcher and the holding element 30 'arranged on the head-side end K holds an axis rod of the upper stretcher. The position of the holding elements 30, 30 'is selected depending on the upper stretcher to be picked up and the position and the distance of the frame rods.

Des Weiteren ist ein Schlosskasten 40 am fußseitigen Ende des Grundkörpers angeordnet. Der Schlosskasten 30 dient in an sich bekannter Weise zur Aufnahme und Sicherung eines Verriegelungselements der Obertrage (nicht dargestellt). Wird die Obertrage auf der Bodenfläche 11 in den Adapter eingeschoben, so tritt das Verriegelungselement über eine Öffnung 43 in den Schlosskasten 40 ein und wird durch dessen integriertes Verriegelungssystem gesichert. Der Schlosskasten 40 weist zudem einen Hebel 41 auf, mit dem das Verriegelungssystem von Hand wieder gelöst werden kann und die Obertrage entlassen werden kann. Die Position des Schlosskastens 40 wird abhängig von der Obertrage und von der Position des Verriegelungselements sowie in Relation zu den Gestellstangen gewählt.Furthermore, a lock case 40 is arranged at the foot end of the base body. The lock case 30 is used in a manner known per se for receiving and securing a locking element of the upper stretcher (not shown). If the upper stretcher is pushed into the adapter on the bottom surface 11, the locking element enters the lock case 40 via an opening 43 and is secured by its integrated locking system. The lock case 40 also has a lever 41 with which the locking system can be released again by hand and the upper stretcher can be released. The position of the lock case 40 is selected depending on the top stretcher and the position of the locking element and in relation to the frame rods.

Wie in Figur 1 dargestellt, zeigen alle Öffnungen 23, 33, 43 - welche weiter unten detailliert beschrieben werden - der beschriebenen Elemente 20, 20', 30, 30', 40 in dieselbe Richtung zum fußseitigen Ende F hin.As in Figure 1 shown, all openings 23, 33, 43 - which will be described in detail below - of the elements 20, 20 ', 30, 30', 40 described point in the same direction towards the foot-side end F.

Figur 2 zeigt eine Explosionsdarstellung des erfindungsgemäßen Adapters aus Figur 1. Gleiche Komponenten sind mit gleichen Bezugszeichen versehen, sodass auf deren erneute Beschreibung verzichtet wird. In dieser Figur 2 sind Verstärkungselemente 27, 27', 37, 37', 47 sowie Befestigungsmittel 28, 28', 38, 38', 39, 39', 48 für die in Zusammenhang mit Figur 1 beschriebenen Elemente dargestellt.

By means of the screws 48, the reinforcing element 47 is fastened to the bottom surface 11 from below through holes provided therefor, and the lock case 40 is fastened to the bottom surface 11. The fastening means 28, 28 ', 38, 38', 39, 39 ', 48 produce a detachable fastening, but in practice it is not necessary to loosen them after assembly - apart from maintenance and cleaning if necessary. Both the upper stretcher and the incubator attachment or the incubator frame can be attached to the adapter without changing or manipulating the attachment means 28, 28 ', 38, 38', 39, 39 ', 48.

Figur 3 zeigt eine isometrische Darstellung des Befestigungsschuhs 20, wobei der Befestigungsschuh 20' gleich ausgebildet ist. Der Befestigungsschuh 20 ist in diesem Ausführungsbeispiel im Wesentlichen würfelförmig, kann aber in anderen Ausführungsformen auch die Form eines Quaders oder eine andere Form aufweisen. Auf der Oberseite und der von nun an als Vorderseite bezeichneten Seite erstreckt sich eine Öffnung 23 ins Innere des Befestigungsschuhs 20. Die Öffnung 23 weist von oben gesehen eine U-Form auf und von der Seite gesehen eine Kastenform auf. In diese Öffnung 23 wird ein Bolzen des Inkubatoraufsatzes bzw. des Inkubatorgestells eingeführt (hier nicht dargestellt). Entlang der U-förmigen Innenseite ist eine Nut 24 ausgebildet, die im eingeführten Zustand des Bolzens in eine Einbuchtung des Bolzens eingreift und somit ein Herausrutschen nach oben verhindert. Die Nut 24 weist an der Vorderseite abgewinkelte Kanten auf, welche das Einführen des Bolzens erleichtert. Des Weiteren weist der Befestigungsschuh 20 zwei Bohrungen 25 senkrecht zur Öffnung 23 durch die zur Vorderseite benachbarten Seiten auf. Die Bohrungen 25 sind Durchgangsbohrungen und liegen auf einer gemeinsamen, durch beide Mittelachsen der Bohrungen 25 führenden Achse. Mit anderen Worten sind die Bohrungen 25 in einer gemeinsamen Höhe und in einer gemeinsamen Tiefe (Abstand zur Vorderseite) angeordnet. In diesem Ausführungsbeispiel sind die Bohrungen 25 in der Mitte der Nut 24 angeordnet. Durch die Bohrungen 25 wird, nachdem der Bolzen des Inkubatoraufsatzes bzw. des Inkubatorgestells aufgenommen wurde, die in Figur 1 beschriebene Verschlussstange 21 eingeschoben, welche dann zwischen dem Bolzen und der Öffnung 23 an der Vorderseite an dem Bolzen entlang läuft und in die Einbuchtung des Bolzens eingreift. Dadurch wird der Bolzen gegen ein Herausrutschen nach vorne und nach oben gesichert. An der hier nicht sichtbaren Unterseite sind Gewinde zur Aufnahme der Schrauben 28 (bzw. 28') vorgesehen. Die Bohrungen 25 sind in solch einer Höhe angeordnet, dass die Verschlussstange 21, wie in Figur 1 gezeigt, über den Rand 12 des wannenförmigen Grundkörpers 10 hinausragt. Figure 3 shows an isometric view of the fastening shoe 20, the fastening shoe 20 'being of identical design. The fastening shoe 20 is essentially cube-shaped in this exemplary embodiment, but can also have the shape of a cuboid or another shape in other embodiments. An opening 23 extends into the inside of the fastening shoe 20 on the top and on the side which is referred to as the front from now on. The opening 23 has a U-shape when viewed from above and a box shape when viewed from the side. A bolt of the incubator attachment or of the incubator frame is inserted into this opening 23 (not shown here). A groove 24 is formed along the U-shaped inside, which engages in an indentation of the bolt in the inserted state of the bolt and thus prevents it from slipping out upwards. The groove 24 has angled edges on the front, which facilitates the insertion of the bolt. Furthermore, the Mounting shoe 20 two holes 25 perpendicular to the opening 23 through the sides adjacent to the front. The bores 25 are through bores and lie on a common axis leading through both central axes of the bores 25. In other words, the bores 25 are arranged at a common height and at a common depth (distance from the front). In this exemplary embodiment, the bores 25 are arranged in the center of the groove 24. Through the bores 25, after the bolt of the incubator attachment or of the incubator frame has been received, the in Figure 1 described locking rod 21 inserted, which then runs along the bolt between the bolt and the opening 23 on the front and engages in the indentation of the bolt. This prevents the bolt from slipping out of the front and upwards. Threads for receiving the screws 28 (or 28 ') are provided on the underside, which is not visible here. The bores 25 are arranged at such a height that the locking rod 21, as in FIG Figure 1 shown, protrudes beyond the edge 12 of the trough-shaped base body 10.

Figur 4 zeigt eine isometrische Darstellung des Halteelements 30, wobei das Halteelement 30' gleich ausgebildet ist. Das Haltelement 30 weist einen Basisabschnitt 31 auf, der auf der Bodenfläche 11 des Grundkörpers aufliegt und einen Schenkel eines U-förmigen Profils darstellt, und einen Halteabschnitt 32 auf, welcher den anderen Schenkel und die Basis des U-förmigen Profils darstellt, sodass der Halteabschnitt 32 und der Basisabschnitt 31 zusammen das U-förmige Profil bilden. Durch das U-förmige Profil wird in Längsrichtung des Halteelements 30 eine Öffnung 33 gebildet, die in Querrichtung durch das gesamte Profil verläuft. In diese Öffnung 33 wird eine Gestellstange der Obertrage eingeführt und von dem Halteabschnitt 32 und dem Basisabschnitt 31 nach oben und unten hin sowie in die Richtung, die der Öffnung entgegensteht, gehalten. Der Halteabschnitt 31 weist am Ende des Schenkels eine abgeflachte Kante 34 auf, durch welche das Einführen der Gestellstange erleichtert wird. Darüber hinaus sind zwei Bohrungen 35 in dem Basisabschnitt 31 vorgesehen, die als Durchgangsbohrungen von oben bis unten durch den Basisabschnitt erstrecken. Durch diese Bohrungen 35 werden die Schrauben 38 (bzw. 38') geführt und in den Einnietmuttern 39 (bzw. 39'), die in der Bodenfläche 11 vernietet wurden, verschraubt, wodurch das Haltelement 20 an der Bodenfläche 11 befestigt wird. Figure 4 shows an isometric view of the holding element 30, the holding element 30 'being of identical design. The holding element 30 has a base section 31, which rests on the base surface 11 of the base body and represents one leg of a U-shaped profile, and a holding section 32, which represents the other leg and the base of the U-shaped profile, so that the holding section 32 and the base portion 31 together form the U-shaped profile. Through the U-shaped profile, an opening 33 is formed in the longitudinal direction of the holding element 30, which extends in the transverse direction through the entire profile. A rack bar of the upper stretcher is inserted into this opening 33 and held up and down by the holding portion 32 and the base portion 31 and in the direction opposite to the opening. The holding section 31 has a flattened edge 34 at the end of the leg, through which the insertion of the rack rod is facilitated. In addition, two bores 35 are provided in the base section 31, which extend as through bores from top to bottom through the base section. The screws 38 (or 38 ') are guided through these bores 35 and screwed into the rivet nuts 39 (or 39') which have been riveted to the bottom surface 11, as a result of which the holding element 20 is fastened to the bottom surface 11.
