Abstract

The invention relates to a chair for patients used in gynaecological and urological examinations. The chair comprises a sitting surface (16) and a back rest. A bar-shaped support (22) for a leg holder (24) is located on each side of the sitting surface (16). Each support (22) has a transverse support (32) at its free end which is not linked to the seat. Each transverse support (22) protrudes in an essentially vertical manner from the bar-shaped support, has a length which equals at least half the width of a leg holder (24) and has a leg holder (24) which is held at its free end by means of a lock-type universal joint (34).

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD OF THE INVENTION

The present invention relates to a gynecological and urological diagnosis patient chair having a seating surface and a backrest, in which rod-shaped supports for leg holders are respectively disposed on both sides of the seating surface.

[0002]

Problems to be solved by the prior art and the invention

In the case of conventional patient chairs of the type described above, the leg holder is usually a so-called Goepel-Beinhalter. Such a leg holder is a shell-shaped footrest, in which a rod is arranged on the underside of the shell, which rod is arranged in a sleeve arranged at the end of each rod-shaped support. And fixed there by fixing screws. By adjusting the rod-shaped support and the leg holder in the support, the leg holder can be brought to a position appropriate for each diagnosis. In the case of the known patient chair, it is of course impossible to adjust the leg holder in such a way that the person to be diagnosed can take an extended recumbent position in which the leg holder can also be used to support the leg. It is.

[0003]

DISCLOSURE OF THE INVENTION

It is an object of the present invention to form a patient chair of the type mentioned at the outset in which the leg holder can be brought into a position suitable for the extended recumbent position of the person to be diagnosed.

According to the invention, the problem is that each support has, at the free end of each support remote from the seating surface, a cross member which projects essentially vertically from this free end, The problem is solved in that the length of the material is at least equal to half the width of the leg holder and the leg holder is held at the free end of the crosspiece via a fixable universal joint.

Because of the universal joint, the leg holder can be adjusted in all arbitrary directions with respect to the support. This adjustment of the leg holder is also not hindered by the support, since the crosspiece allows the leg holder to be shifted laterally with respect to the support. This allows the support to swing with the leg holder so that the leg holder can be carried on one surface with the seating surface and the backrest.

[0006] Preferably, the universal joint is a spherical joint. The support may have the shape of at least approximately a quarter arc and the end of the support remote from the crosspiece is parallel to the front edge of the seating surface via a fixable joint. Is hingedly connected to the seating surface about an essentially horizontal pivot axis directed toward the seat. This joint can likewise be formed as a universal joint, for example as a spherical joint, so that the support can be adjusted over a wide angular range.

[0007] In order to be able to adjust the support by means of the respective leg holder even under load, a weight balancing device, which may for example comprise a gas spring, can be connected to the support.

[0008] Other features and advantages of the invention will become apparent from the following description, which describes the invention based on embodiments and with reference to the accompanying drawings.

BEST MODE FOR CARRYING OUT THE INVENTION

The patient chair shown in FIG. 1 includes a bottom 10 and a post 12 coupled to the bottom that carries a chair portion, generally indicated at 14. The chair part is a horizontal swing shaft 20
A seating surface 16 and a backrest 18 that are jointly coupled to each other about the center. The chair portion 14 is coupled to the post 12 in a manner not shown, and more particularly, the seating portion 16 and the backrest 18 are adjusted to a common height, as well as the seating surface 16 and the backrest 18 of FIG. Seating or diagnostic position, which forms with each other at a slight angle, and a resting position in which the seating surface and the backrest lie essentially in one plane, thus allowing an extended horizontal resting position (FIG. 2) of the patient. The seating portion and the backrest are coupled such that they can also be adjusted with respect to each other. Seating surface 1
The adjustment of 6 and the backrest 18 can be made in any manner and will not be described in detail here.

An arc-shaped, rod-shaped support 22 for a so-called Goepel-Beinhalter 24 is connected to the seating surface 16.
The einhalter, in the seated or diagnostic position, supports the leg of the person to be diagnosed in the region of the lower leg and popliteal as shown in FIG. Next, the support 22 and the fixing of the leg holder 24 to the support 22 will be described in detail with reference to FIGS.

According to FIGS. 3 and 4, one end of each support 22 is hinged via a spherical joint 26 to an arm 28 connected to the seating surface 16. Spherical joint 26
Can be held at a predetermined position via the rotation button 30. Thereby, the support 22 can swing about the horizontal axis between the position shown in FIG. 1 and the position shown in FIG. 2, for example.

At the end of the support 22 remote from the spherical joint 26, the support has a crosspiece 32 oriented inwardly perpendicular to the support, ie in the direction of the seating surface 16, and its free end. Each leg holder 24 is supported by a part via a spherical joint 34. In this case, the leg holder 24 can likewise be fixed again in a defined position via the rotary button. By shifting the leg holder 24 sideways with respect to the support 22,
The leg holder can be arranged such that the leg holder 24 is substantially in one plane with the seating surface 16 and the backrest 18 as shown in FIG. In this case, a part of the leg holder 24 is located on the side of the support 22. Without this lateral displacement, the leg holder 24 would hit the support 22 so that the leg holder would not be able to align with the seating surface 16 and the backrest 18.

A support rod 36 and a foot plate 38 are further fixed to the arm 28.

In the embodiment according to FIGS. 5 and 6, the support 22 has an extension 40 projecting beyond the spherical joint 26, which projection is gripped by one end of a gas spring 42. The other end grips the support rod 36 for the foot plate 38. The gas spring 42 is used for weight balancing in order to allow easier adjustment of the support 22 and the leg holder 24 even under load, ie when the legs are on.

Due to the arcuate bending, the support 22 can be used at the same time as a grip and as a support for the legs of a person sitting on a chair.
