B. 15 cm above the lower edge of the input surface, it may be sufficient to replace the film by 15 cm - in a conveying movement assumed here from top to bottom - or run through down. This embodiment may advantageously contribute to the saving of film material.

Instead of determining the length from the above information, the length may be directly from the actuated area of the input surface. For example, it can be specified that pressing one of the upper buttons always replaces x cm of foil or should run after, while pressing one of the lower buttons only replaces y cm (with x> y). A conversion or conversion of a sensor result can therefore be omitted here.

In some embodiments, the predetermined length is thus variable. However, it is also predetermined, as a priori information can be made about the length of which the film will be further promoted. The length to be carried forward may change between, for example, the next and the next but one operation of the input surface. But it is reproducible and above all predictable.

In certain embodiments, the actuation device of the treatment device is programmed to move or convey the receptacles for the film or layer-or the film or the layer itself-in such a way that, in use, the film or the layer, for example, in an upright position. and down, back and forth and / or up and down or any other back and forth or pendulum movement.

In certain embodiments, the attachment or conveyor is configured for manual conveyance, as an alternative or supplement to machine conveyance, such as battery or battery operated.

In some embodiments, the attachment or conveyor is part of the treatment device. In other embodiments, they may be releasably connected to the treatment device, such as a frame or stem, e.g. B. by means of screw, clamp connection, plug connection, snap connection, magnetic connection or the like can be connected and optionally has corresponding connecting portions.

In some embodiments, the film is flexible. In certain embodiments, the layer is not flexible.

In some embodiments, the film has a thickness between 60 and 240 microns, preferably between 80 and 160 microns, more preferably a thickness of 120 microns. The film material is thus preferably highly flexible and has high elastic expansion properties. This allows a particularly good haptic feedback and / or effect when operating a touch screen or keyboard keys.

In some embodiments, the film or layer has no section, in particular no bending section that would differ from adjacent sections of the film or layer.

In some embodiments, the attachment and / or the conveyor device comprises a tensioning device to hold the film under a predetermined tension.

In some embodiments, the film or layer is at a fixed distance from the input surface. Thus, it can be ensured that conveying the film or layer relative to the input surface does not cause any input, for example by the film unintentionally touching a button of the touch screen or a key on the keyboard.

In some embodiments, the treatment device or attachment has a spacer device. The spacer device is configured and arranged to hold the film, as it is being conveyed or transported past the input surface, below a, possibly variable, distance from the input surface. For example, the foil, which may, for example, move surface parallel to the input surface, does not contact or rub against the input surface as it is being delivered. Thus, the engine that causes its movement may advantageously be comparatively weak for lack of friction.

The spacer device may be configured and arranged to bring the film back to or in contact with the latter after the completion of a conveyance operation, or to allow it to be in the original distance from the input surface.

In some embodiments, the disinfecting device and the input surface are arranged so as not to be relatively movable. Optionally, they can not change their position relative to each other.

In some embodiments, the disinfection device is configured to be manually or mechanically extendable or extendable, such as electrically powered, such as over an extended arm, to deliver sanitizer to the input surface, film, or layer.

In some embodiments, the treatment device and / or the attachment has no means for applying disinfectant, in particular liquid, to the input surface or directly to it, in particular not by spraying, brushing, wetting, etc.

Some or all embodiments according to the invention may have one, several or all of the advantages mentioned above and / or below.

It is advantageous that the input surface does not have to be touched for input itself when using the present invention. It is sufficient to touch the film or layer arranged above it. This can easily be kept sufficiently hygienic, clean or sterile by, for example, moving a fresh portion of the film over the input surface after each actuation of the input surface by the film or layer. Thus, the user who operates the input surface, always touched only hygienic material.

In this way it can be advantageously ensured that hygienically objectionable material such as germs, blood, etc., is not transmitted between different persons who successively actuate the input surface.

But this infection can be advantageously prevented and / or spread of germs. Cross-contamination (such as between different, simultaneously treated patients or the respective treatment devices used or their input surfaces) are also limited.

In addition, other measures that have hitherto been taken to prevent infection, germ transmission, etc., may become redundant or their scope may be reduced. This includes the previously practiced dressing and / or changing disposable gloves. In this case, the doctor has already tightened or changed gloves for once to actuate the input surface, for example to end an alarm or even a false alarm, when, while they were busy with a first patient, the treatment device of another, second patient Input required, again an alarm or even false alarm had to be confirmed, etc., without z. B. to come into contact with the other patient or with the other patient treating treatment device.

In addition to saving material, such. As the aforementioned gloves, can be saved with the help of the present invention also time and effort, such as when changing the gloves, during storage, ordering, manufacturing, etc.

Furthermore, disinfecting media such as cleaning fluids can be saved, which are not required when using the present invention for disinfecting the input surface. The time required for disinfecting the input surface can also be saved.

Another advantage is that the staff can be saved from some mistakes, the z. B. due to the fact that was once forgotten to change gloves. This risk can be lowered according to the invention.
