Description

Die Erfindung betrifft eine Vorrichtung zur Unterstützung der Beine an einem gynäkologischen Untersuchungs-und Entbindungsstuhl, der ein in beliebigen Neigungen einstellbares Rückenteil, ein Sitzteil und ein Beinteil, das aus einer mit dem Sitzteil fluchtenden Lage in eine abgesenkte, die ganze oder teilweise Verlagerung unter das Sitzteil und das Rückenteil ermöglichende Lage gebracht werden kann, sowie an den beiden Seiten des Stuhlrahmens angeordnete, einstellbare Fußstützen und Oberschenkelstützen aufweist.The invention relates to a device for supporting the legs on a gynecological examination and delivery chair, which has a back part which can be adjusted in any inclinations, a seat part and a leg part which, from a position aligned with the seat part, into a lowered position, in whole or in part, under the Seat part and the back part enabling position can be brought, as well as arranged on both sides of the chair frame, adjustable footrests and thigh supports.

Bekannte Stühle dieser Art sind so ausgebildet, daß die Patientin eine im wesentlichen waagerechte Lage, eine sitzende Stellung oder auch eine Zwischenstellung einnehmen kann. Zu diesem Zweck weisen die Stühle ein Rückenteil auf, das aus einer horizontalen Lage in eine im wesentlichen senkrechte Stellung geschwenkt werden kann, sowie ein an dem Gestell des Stuhls angeordnetes Sitzteil und ein Beinteil, das aus einer mit dem Sitzteil fluchtenden Lage in eine Lage abgesenkt werden kann, in der es ganz oder teilweise unter das Sitzteil und das Rückenteil geschoben werden kann.Known chairs of this type are designed so that the patient can assume an essentially horizontal position, a seated position or an intermediate position. For this purpose, the chairs have a back part which can be pivoted from a horizontal position into a substantially vertical position, as well as a seat part arranged on the frame of the chair and a leg part which is lowered into a position from a position aligned with the seat part can be in which it can be fully or partially pushed under the seat part and the back part.

Auf den beiden Seitenteilen des bekannten Stuhlgestells ist ein Kopf zur einstellbaren Halterung einer Stange angeordnet, die an ihrem einen Ende eine Fußstütze aufweist. Auf diese Weise kann die Stange der jeweiligen Beinlänge der Patientin angepasst und in eine gewünschte, im wesentlichen senkrechte Lage geschwenkt werden, um die Beinstütze in die gewünschte Hochlage zu bringen. Ein Stuhl dieser Art ist aus den SE-PS 342 549 und 355 723 bekannt. Die Möglichkeiten der Einstellung der Fußstützen sind jedoch bei diesen Stühlen ziemlich beschränkt, da die die Fußstützen tragenden Stangen nur in einer Ebene verschwenkt werden können. Außerdem sind bei diesen Stühlen keine Unterstützungen für die.Oberschenkel vorgesehen.On the two side parts of the known chair frame, a head for the adjustable mounting of a rod is arranged, which has a footrest at one end. In this way, the rod can be adapted to the patient's respective leg length and converted into a desired, in essential vertical position can be pivoted to bring the legrest into the desired high position. A chair of this type is known from SE-PS 342 549 and 355 723. The possibilities of adjusting the footrests are, however, rather limited in these chairs, since the rods carrying the footrests can only be pivoted in one plane. In addition, no support is provided for the thighs on these chairs.

Aus den US-PS 1 622 313, 2 067 891 und 2 306 031 sind des weiteren Stühle dieser Art bekannt, bei denen zwar mit den Fußstützen in Verbindung stehende Unterstützungen für die Oberschenkel vorgesehen sind, die Einstellmöglichkeiten reichen jedoch nicht aus, um einer Patientin eine den jeweiligen Bedürfnissen entsprechende Lage der Beine zu ermöglichen.Furthermore, chairs of this type are known from US Pat. Nos. 1,622,313, 2,067,891 and 2,306,031, in which supports for the thighs are provided in connection with the footrests, but the adjustment options are not sufficient for a patient to enable the legs to be positioned according to their needs.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Stuhl der genannten Art so auszubilden, daß die Beinstützteile leicht den individuellen Gegebenheiten einer Patientin angepaßt werden können und die für sich einstellbaren Fußstützen zusammen mit den Oberschenkelunterstützungen um zwei zueinander senkrechte Achsen geschwenkt werden können.The invention is therefore based on the object to design a chair of the type mentioned so that the leg support parts can be easily adapted to the individual circumstances of a patient and the adjustable footrests together with the thigh supports can be pivoted about two mutually perpendicular axes.

Diese Aufgabe wird gemäß der Erfindung mit den Mitteln gelöst, die die kennzeichnenden Merkmale des Anspruchs 1 und in vorteilhafter Weiterbildung dieser Mittel die kennzeichnenden Merkmale der Ansprüche 2 und 3 bilden.This object is achieved according to the invention with the means which form the characterizing features of claim 1 and, in an advantageous development of these means, the characterizing features of claims 2 and 3.

In the drawing, an embodiment of the invention is shown in a schematic manner. Show it:
  • Fig. L is a perspective view of the chair for a patient taking a seated posture with raised legs apart;
  • 2 shows a perspective side view of the right leg support part;
  • 3 shows a vertical section through the pivotable bearing head carrying the footrest;

  • 6 is a side perspective view of the leg support member;
  • Fig. 7 is a side view of the chair in a position in which the patient's thighs are essentially in a vertical position and the lower legs rest on the footrests pivoted inwards.

Wie aus Fig. 7 ersichtlich ist,ruht der Seitenholme 10 aufweisende Rahmen des Stuhls auf einer in der Höhe verstellbaren Tragsäule 11 und kann als Ganzes um die Achse 12 geschwenkt werden.As can be seen from FIG. 7, the frame of the chair having side rails 10 rests on a height-adjustable support column 11 and can be pivoted as a whole about the axis 12.

Der als Ganzes mit 13 bezeichnete Stuhl weist ein neigbares Rückenteil 14, ein Sitzteil 15 und ein Schenkelteil 16 auf, das in eine mit dem Sitzteil 15 fluchtende Lage oder in eine gesenkte Lage gebracht werden kann, in der es ganz oder teilweise unter das Sitzteil 15 geschoben werden kann.The chair designated as a whole by 13 has an inclinable back part 14, a seat part 15 and a leg part 16 which can be brought into a position aligned with the seat part 15 or into a lowered position in which it is wholly or partly under the seat part 15 can be pushed.

Zu beiden Seiten des Rahmens 10 ist eine Beinstützvorrichtung 17,18 angeordnet, die Fußstützen 19,20 und einstellbare Oberschenkelunterstützungen 21,22 aufweist. Im folgenden wird im wesentlichen nur die rechtsseitige Vorrichtung 17 beschrieben.A leg support device 17, 18 is arranged on both sides of the frame 10, the foot supports 19, 20 and has adjustable thigh supports 21, 22. In the following, essentially only the right-hand device 17 is described.

An dem Holm 10 ist mittels Bolzen ein Lagerkragstück 23 befestigt, wie dies aus den Figuren 4 und 5 ersichtlich ist. Das Lagerkragstück 23 weist eine mittels Bolzen an dem Holm 10 befestigte Platte 24 und ein Traglager 25 mit einer senkrechten zylindrischen Bohrung 26 auf, die den zylindrischen Teil 27 einer Lagerhülse 28 aufnimmt, die einen oberen Flansch 29 aufweist, der auf der oberen Stirnfläche 30 des Traglagers 25 aufliegt (Fig. 3 und 4).A bearing collar piece 23 is fastened to the spar 10 by means of bolts, as can be seen from FIGS. 4 and 5. The bearing collar piece 23 has a plate 24 fastened to the spar 10 by means of bolts and a support bearing 25 with a vertical cylindrical bore 26 which receives the cylindrical part 27 of a bearing sleeve 28 which has an upper flange 29 which is on the upper end face 30 of the Support bearing 25 rests (Fig. 3 and 4).

Die zylindrische Bohrung 31 der Lagerhülse 28 nimmt in sich den zylindrischen senkrechten Stab 32 auf, der in beliebiger Höhen- und Winkellage mittels des Bolzens 33 festgestellt werden kann. In gleicher Weise wird die Lagerhülse 28 in dem Traglager 25 mittels eines Schraubenbolzens 34 festgeklemmt.The cylindrical bore 31 of the bearing sleeve 28 receives the cylindrical vertical rod 32, which can be fixed in any desired height and angle by means of the bolt 33. In the same way, the bearing sleeve 28 is clamped in the support bearing 25 by means of a screw bolt 34.

An dem Flansch 29 der Lagerhülse 28 ist eine kreisrunde Platte 35 angeschweißt, an der ein waagerechter Lagerzapfen 36 angeordnet ist, der dem Lagerkopf 37 als Schwenklager dient. Der zweiteilig ausgebildete Lagerkopf 37 weist seitlich des Lagerzapfens 36 eine senkrecht zu diesem sich erstreckende Bohrung 38 auf, in der die Stange 39 festgeklemmt werden kann. Die beiden Teile 40,41 des Lagerkopfes 37 sind zur Vermeidung einer gegenseitigen Verschwenkung über einen Bolzen 42 miteinander verbunden. Jeder dieser beiden Teile 40,41 weist zur Bildung der Bohrung 38 eine randoffene halbzylindrische Aussparung auf.Sie werden mittels eines ein Gewinde aufweisenden Kopfbolzens 43, an dem ein Hebel 44 angreift, gegeneinander und damit auch gegen die Platte 35 gepreßt, so daß die Stange 39 festgeklemmt und der Lagerkopf 37 gegen Ver~ schwenkung gesichert ist.A circular plate 35 is welded to the flange 29 of the bearing sleeve 28, on which a horizontal bearing journal 36 is arranged, which serves as a pivot bearing for the bearing head 37. The two-part bearing head 37 has a bore 38 extending perpendicularly to the side of the bearing journal 36 and in which the rod 39 can be clamped. The two parts 40, 41 of the bearing head 37 are connected to one another via a bolt 42 in order to avoid mutual pivoting. Each of these two parts 40, 41 has a semi-cylindrical recess which is open at the edge to form the bore 38. They are pressed against one another and thus against the plate 35 by means of a threaded head bolt 43 on which a lever 44 engages, so that the rod 39 clamped and the bearing head 37 is secured against pivoting.

Die Stange 39 weist eine Mehrzahl von Ringnuten 45 auf, in die ein unter der Einwirkung einer Feder stehender Verriegelungsbolzen 46 eingreift, um die Stange gegen eine Längsverschiebung zu sichern. Die Stange 39 weist an ihrem vorderen Ende eine senkrecht zu ihrer Achse angeordnete Hülse 47 auf, in die ein mit der Fußstütze 19 verbundener Lagerzapfen 48 eingreift, der mittels einer mit dem Hebel 49 betätigten Stellschraube festgeklemmt wird. Die Fußstütze 19 kann somit verschiedene Winkelstellungen einnehmen und kann auch längs der Hülse 47 verschoben werden. Die Fußstütze 19 weist an ihrer Oberseite 50 eine dem Fuß entsprechende Vertiefung auf, um ein Abgleiten des Fußes zu verhindern. Die gegenüberliegende Seite 51 ist so ausgebildet, daß sie dem Unterschenkel eine Unterstützung bietet, wenn die Patientin eine der in Fig. 7 dargestellten Einstellung des Stuhls entsprechende Lage mit im wesentlichen senkrecht weisenden Oberschenkeln einnimmt. Bei dieser in Fig. 7 dargestellten Einstellung des Stuhls sind die Stäbe 32mit den Oberschenkelstützen 21,22 entfernt. Die Fußstützen 19,20 können nach innen oder außen geschwenkt werden, indem der Lagerkopf 37 um die Achse-der Bohrung 26 in dem Traglager 25 geschwenkt wird.The rod 39 has a plurality of annular grooves 45, into which a locking bolt 46 engages under the action of a spring, in order to secure the rod against longitudinal displacement. The rod 39 has at its front end a sleeve 47 arranged perpendicular to its axis, into which a bearing pin 48 connected to the footrest 19 engages, which is clamped by means of an adjusting screw actuated with the lever 49. The footrest 19 can thus assume various angular positions and can also be moved along the sleeve 47. The footrest 19 has on its upper side 50 a depression corresponding to the foot in order to prevent the foot from sliding off. The opposite side 51 is designed in such a way that it offers support to the lower leg when the patient assumes a position corresponding to the setting of the chair shown in FIG. 7 with the thighs pointing essentially vertically. With this setting of the chair shown in Fig. 7, the bars 32 with the thigh supports 21, 22 are removed. The footrests 19, 20 can be pivoted inwards or outwards by pivoting the bearing head 37 about the axis of the bore 26 in the support bearing 25.

Die Oberschenkelstütze 21 ist in einem Bügel 52 um die Querachse 53 schwenkbar gelagert und der Bügel selbst kann um einen Zapfen 55 geschwenkt werden, der rechtwinklig zu dem Arm 56 angeordnet ist. Auf dem Zapfen 55 ist eine Distanzhülse 54 angeordnet. Der Arm 56 ist in einer Hülse 57 gelagert, die am oberen Ende des Stabs 32 senkrecht zur Stabachse angeordnet ist. Mittels eines Stellschraubenbolzens 58 wird der Arm 56 in der Hülse 57 festgeklemmt.The thigh support 21 is pivotally mounted in a bracket 52 about the transverse axis 53 and the bracket itself can be pivoted about a pin 55 which is arranged at right angles to the arm 56. A spacer sleeve 54 is arranged on the pin 55. The arm 56 is mounted in a sleeve 57 which is arranged at the upper end of the rod 32 perpendicular to the rod axis. Using a set screw bolt 58 the arm 56 is clamped in the sleeve 57.

Die Ausbildung der beiden Vorrichtungen 17,18 erlaubt eine weitgehende Bewegungsfreiheit des Arztes, wenn das Beinteil 16 sich ganz oder teilweise unter dem Sitzteil 15 befindet.The design of the two devices 17, 18 allows the doctor to move as far as possible if the leg part 16 is located wholly or partly under the seat part 15.

Die Beine der Patientin können somit durch Anpassung der Fußstützen 19,20 und der Oberschenkelstützen 21,22 bequem in jeder gewünschten Lage unterstützt werden. Da die Lagerhülsen 28 je eine starre Einheit einer mit einer Fußstütze verbundenen Oberschenkelstütze tragen, kann jede Einheit je nach dem gewünschten Spreizwinkel der Beine nach innen oder außen geschwenkt werden, ohne daß es einer neuen Einstellung der Fußstützen bzw. der Oberschenkelstützen bedarf.The patient's legs can thus be comfortably supported in any desired position by adapting the foot supports 19, 20 and the thigh supports 21, 22. D a is the bearing sleeves 28 each carry a rigid unit means connected to a footrest thigh support, each unit may vary depending on the desired angle of spread of the legs inwardly or be swung outwardly, without requiring a new adjustment of the footrests or the thigh supports.
