Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD OF THE INVENTION

The present invention is particularly for gynecological and urological diagnostics having a seating surface, a backrest and a holder for a roller of replaceable strip-shaped cover material for at least partially covering the seating surface and the backrest. Patient chair.

[0002]

Problems to be solved by the prior art and the invention

Such a patient chair is known, for example, from DE 30 36 191 A1. In the solution disclosed in this document, a bearing shell for the wrapping paper is arranged below the seating surface, and the paper sheet is pulled out through the gap between the seating surface and the backrest and placed above the seating surface. Can be. The above solution has the disadvantage that the lower part of the backrest cannot be covered.

While there may be a method of pulling the paper sheet backwards through the backrest and through the seating surface, this method tends to displace the material strip and results in a very high amount of material used per patient. Has inconvenience.

[0004]

DISCLOSURE OF THE INVENTION

The task of the invention is to ensure that at least the lower part of the backrest and the seating surface can be covered with a minimum of material usage and that a more reliable holding of the material strip on the surface to be covered is ensured. Secondly, to form a patient chair of the kind mentioned at the outset.

According to the invention, the above-mentioned object is solved by arranging a roller holder on the back of the backrest and by forming a slit in the backrest for passing a strip of material.

With the solution according to the invention, the use of cover material per patient is only required for the part to be covered and the seating surface of the backrest. At the same time, the strip of material is protected from lateral misalignment by the longitudinal ends of the slit. The rollers of the cover material are easily accessible and can therefore be replaced without difficulty.

[0007] Preferably, the holder is formed as a tub-shaped bearing container for the rollers, so that the rollers can simply be inserted into the bearing tabs.

On the one hand, in order to be able to easily disinfect the patient chair to meet hygiene requirements, and on the other hand, to provide a way in which different specifications of the patient chair can be provided, It is further proposed according to the invention to provide a frame at least partially covered by a replaceable cushion on each of the seating surface or the backrest or both of the seating surface and the backrest. To clean and disinfect the patient chair, the cushion can be removed so that the cushion and frame can be handled separately.

Preferably, the cushion comprises a bonding material having a cushion support and a sealed cover layer. The cushion can be fixed to the frame by, for example, a button or a hook-and-loop fastener. Such a replaceable cushion can of course also be provided in the case of a patient chair without the above-mentioned holder for the roller of strip-shaped cover material.

[0010] Patient chairs for gynecological and urological diagnosis are usually provided with so-called storage shells for collecting body fluids or lavage fluids. It is a further object of the present invention to provide a patient chair that is always available without the need for a storage shell when it is not needed.

According to the present invention, the above-mentioned problem is solved by the storage shell being swingable below the seating surface, wherein the swinging shaft is located near the front edge of the seating surface, It also extends at least approximately through the shell edge of the storage shell.

In this manner, the shell can be easily swung under the seating surface when not in use, and can be swung out when used.

[0013] Preferably, the storage shell has not only an outlet but also a connection for the cleaning medium, and is mounted so that the shell base falls down from the inlet opening for the cleaning medium.
This causes the liquid to collect in the storage shell at a deeper location away from the connection for the cleaning medium. It is ensured that the liquid present in the storage shell when the supply of the cleaning medium is interrupted reaches the supply for the cleaning medium and can contaminate the cleaning medium.

[0014] Preferably, the containment shell has a circular shape with edges which are drawn inwardly, in which case the connection for the cleaning medium is such that the incoming cleaning medium has a circular tangential velocity. Formed and arranged to obtain. This ensures that the incoming cleaning medium generates a circular flow and that the entire area of the shell is cleaned.

[0015] Other features and advantages of the present invention will become apparent from the following description of an embodiment thereof, taken in conjunction with the accompanying drawings.

BEST MODE FOR CARRYING OUT THE INVENTION

The gynecological examination chair shown in FIG. 1 includes a foot plate 10 and a post 12 coupled to the foot plate, the post carrying a chair portion, generally indicated at 14. The strut has a guide body 16 fixedly connected to the foot plate 10, on which the stigma 18 is guided in an extendable and retractable manner. The actuator for adjusting the height is arranged inside the column 12 and can be formed, for example, by a hydraulic cylinder or an adjusting spindle.

The chair portion includes a backrest 20 that is pivotally hinged about a pivot axis 22 of the capital 18, such that the chair portion 14 is tilted about the axis 22 of the capital 18. Can be. The adjustment mechanism required to pivot the chair portion 14 is not critical to the present invention and will not be described in detail here.

The seating surface 24 and the backrest 20 are swingably connected about another swing shaft 26.

Below the seating surface 24, a carrier 28 is fixed on each side, on which a bent foot plate 30 for fixing the foot of the person to be diagnosed is fixed. The free end of the footplate is reconnected to the seating surface 24 via a rod 32 bent approximately semi-circularly and is used as a handle or support for resting the leg of the person to be diagnosed.

On the back of the backrest 20 is arranged a bearing shell 34 for receiving the rollers 36 of the material strip 38. The strip of material 38 can be, for example, a paper sheet divided into individual parts by perforation lines. A slit 40 is formed in the backrest 20, through which the material strip 38 can pass through from the bearing container 34, so that the material strip is below the slit 40, as can be seen from FIG. It can be placed over the part of the backrest 20 and the seating surface 24 that have been placed. The length of the portion of the material strip 38 between the two perforations is at most the length of the seating surface 24 and the backrest 2 located below the slit 40.
0 length. The bearing container 34 may be foldable to replace the rollers 36.

In the illustrated embodiment, the backrest comprises a pipe frame 42 covered by a cushion 44. The cushion comprises, for example, a thick skin or cover layer 46 that is combined with a cushion layer 48. Cushion 44 can also be manufactured as a composite material or as a unitary material. The fixing of the frame 42 to the cushion 44
For example, it can be performed by the surface fastener 50 shown in FIG.

Similarly, the seating surface and grip holder 32 may be covered with cushioning material.

Below the seating surface 24, the storage shell 54 is pivotally supported about an axis 56 substantially perpendicular to this shell edge near the holder 52, in which case FIG.
The bearing is performed so that the shell base falls downward away from the bearing position, as shown in FIG. In this way, the storage shell 54 can swing between the position shown by the continuous line below the seating surface 24 and the use position shown by the broken line when not in use, in this use position. , The storage shell projects above the front edge of the seating surface 24. Close to the bearing position, the storage shell 54 has a connection for a supply pipe 58 through which the cleaning medium can be guided to the storage shell 54. It is understood that the irrigation medium and possibly bodily fluids may collect in a deep location opposite the irrigation liquid inlet of the storage shell 54. This prevents the liquid collected in the storage shell 58 from reaching the supply pipe 58 and possibly contaminating the supply pipe when the supply of the cleaning liquid is interrupted.
