Description

Devices for instrumentation units

technical field

Medical devices or instruments, like for example C-arms or radiography/fluoroscopy devices, can be controlled by means of an instrument unit designed as an operating panel. Touch-sensitive control elements are also arranged on such instrument units or operating panels.

Background technique

The touch-sensitive control elements also feature a graphical user interface. With the aid of such a graphical user interface, also referred to as a touch screen, the user can be intuitively and interactively guided through the program segments within the guidance user interface via the human-machine interface. On a user interface with touch-sensitive control elements, processing programs can be started by means of these touch-sensitive control elements and the x-ray images shown on the graphical user interface can be selectively processed. Touch-sensitive control elements in the user interface have sliders in addition to flat elements such as switching elements. The operation of these control elements is based on the principle that the user can lightly touch the touch-sensitive control elements, for example with a pointer or a finger. In addition to lightly touching control elements, processes such as zooming can also be carried out on the touch screen by means of a pointer or a dragging motion of a finger. This operation is also called drag & drop. Intuitive operating concepts are increasingly being used on graphical user interfaces. For example, the user can lightly touch the image and/or control elements on the touch screen, and can rotate, zoom or further interact with the image by dragging on the touch screen or multi-touch screen with one or more fingers, such as Multiple selection of data or management of patient data, etc.

Medical equipment or instruments with the above-mentioned type of operation panel are also applied in the operating environment. However, application in a surgical environment requires compliance with sterility regulations. A disadvantage is that operating panels of this type cannot be sterilized like surgical instruments because of the electronics integrated there. In order that the operator panel can still be used in the sterile field, a sterile, usually transparent film, a so-called drapes, is used. For this purpose, wrap the operator panel with a sterile film. However, wrapping the operating panel with a sterile film inherently entails the disadvantage when operating the touch screen element that only a restricted use of the touch screen element is possible. Furthermore, it is extremely error-prone when performing so-called tap operations, such as drag operations with one or more fingers. Thus, when a finger is moved across the touch-sensitive display, the sterile film covering the display moves with it, thereby erroneous sensory recognition of actions on the touch-sensitive display.

FIG. 1 shows an operating panel and a cover unit AE covering the operating panel in a sectional view.

detailed description

In an exemplary embodiment, a device configured as a cover unit for an instrument unit configured as an operating panel is described. In order to use the operating panel in the sterile area, a cover unit is designed for the operating panel, the surface contour of which is copied from the surface of the operating panel, and the material is designed according to the area of the functional unit located below, so that it can be used unobstructed Mechanical and sensitive operating and control elements of the operator panel.

In the illustrated FIG. 1 , a sectional view of an operation panel and a cover unit AE covering the operation panel is shown. The section extends along the longitudinal sides of the control panel BK.

The operating panel BK shown in section has, in addition to sensitive control elements in/on a flat monitor designed as a touch screen M, mechanical operating elements such as buttons MBT and/or also operating Rod MBJ. In addition, at least one first sensor S1 for identifying the cover unit AE covering the operating panel BT and at least one second sensor S2 , for example for a touchscreen controllable by means of infrared radiation, are shown.

Covering unit AE covers at least the upper surface and side surfaces of operation panel BK. The lower surface of the control panel BK can likewise be covered or wrapped with the same cover unit AE. The cover unit AE is made of transparent and flexible plastic. In order to use the control panel BK in the area to be kept sterile, it is covered with a cover unit AE. The cover unit AE can be designed as a disposable or as a reusable unit. The material covering the elements AE must be designed to be heat-treated, eg steam sterilized, UV-irradiated and/or chemically treated during the sterilizing process. In addition, the material for covering the unit can optionally be made of anti-corrosion plastic. To minimize friction between the user's fingers/gloves, the surface of the touchscreen area can be optionally coated.

Due to the differently shaped surfaces and the different functions of the operating and control elements arranged on the control panel BK, the cover unit AE has, for example, differently shaped regions B1 , . In these areas, the transparent plastic used is adapted to the functional unit located below. This adaptation includes, for example, flexibility, thickness, transparency and surface state of the plastic in addition to the shape.

The first area B1 extends over the surface of the touch screen M. As shown in FIG. In this first region B1, the thickness of the cover unit AE is designed such that user inputs can be detected by the touch screen. For this purpose, the surface also has a certain rigidity, so that, in addition to a light touch with a finger, operations such as pulling or pulling down are also possible. As an alternative, a stiffening frame is installed around the active touchscreen surface, that is, the membrane in the touchscreen area, while flexible enough for some interactions, needs to be clamped and held in place by the frame.

Except for the thickness and rigidity of the material, a first sub-area S1B1 completely consistent with the input area on the touch screen M is provided in the first area B1. The first subregion S1B1 has a tactilely perceivable surface structure. For this purpose, for example, the surface structure of the respective first subregion S1B1 is designed to be higher and/or lower than the surface level of the first region B1. In addition, these surfaces can have different surface structures. These surfaces can be provided with, for example, bumps, lines or a higher surface roughness. In order to perform sliding or dragging operations on the touch screen, a second sub-region S2B1 is provided in the first region B1, and the surface roughness of the second sub-region S2B1 is designed to be smaller than that of other regions. This configuration of the surface of the second subregion S2B1 is particularly suitable for use in an operating room where latex gloves are to be worn.

In the edge area of the first area B1, a second area for the second sensor S2 is provided. The second sensor S2, for example constructed in infrared technology, is a transmitting and receiving unit for detecting the input position on the surface of the touch screen. In this second area B2, the covering unit is provided with a so-called light window. This light window allows information or infrared signals to pass unimpeded between the transmitter and receiver.

Above the mechanical operating elements such as the button MBT and/or the joystick MBJ, the cover unit AE is provided with a third region B3. In this case, the material of the cover unit AE is designed to be easily deformable and adapted to the function of the individual mechanical operating elements. The contours of the mechanical operating elements MBT, MBJ can be copied with certain tolerances in the cover unit AE. The tactile feedback from the mechanical operating elements is conveyed to the user via the material of the cover unit AE when actuating these mechanical operating elements.

The lateral surface of the operation panel BK is completely covered by the covering unit AE. Covering of the base can likewise be achieved by means of the cover unit AE. For this purpose, the cover unit AE is designed in the form of a pocket and is provided with overlapping locking elements in the region of the opening, which is arranged on the narrow side. In the lateral area, the cover unit AE has a fourth area B4. In this fourth region B4 the cover unit AE rests in a form-closed manner on the side regions of the control panel BK. Whether the cover unit AE rests positively against the side regions of the control panel BK is detected by a first sensor S1 integrated in the control panel BK. Feedback to the higher-level computing and signaling unit. With the aid of the first sensor S1 , it is possible to capture the information as to whether the originally non-sterile control panel is provided with a sterile covering unit AE.

Depending on the shape of the control panel BK, a fifth region B5 is provided in the cover unit AE. In this fifth region B5 the material does not have a specific shaping for its surface structure.

Furthermore, sliding of the individual areas B1 , . . . , B5 , especially the first area B1 on the touch screen, is prevented by means of the form-closed connection of the cover unit AE to the lateral areas of the operating panel BK. In addition, in order to prevent the cover unit AE from slipping locally on the control unit BK, the underside is provided with an adhesive surface and/or an electrostatic charge by means of which the film can likewise be adhesively covered on the control panel BK. Creases can also be prevented by designing the sterile covering unit to have different thicknesses. The thickness and hardness of the material are selected in such a way that, on the one hand, the operation and function of the underlying touch screen are possible, and on the other hand, the first area B1 is rigid, so that the movement of the user's fingers is not affected. Can cause slippage or wrinkling. By coating the second sub-region S2B1 of the first region B1, the surface friction can be reduced, so that the user of the operation panel BK feels less sliding resistance when pulling on the first region B1.

In the third region B3, where the mechanical switch MBT or the joystick MBJ is located, the material of the covering unit AE is provided with a lower hardness. Cover unit AE has raised and embossed shapes in this region, so that operating elements MBT, MBJ always have the freedom of movement assigned to them. Furthermore, when an infrared touch screen is used, the second region B2 of the cover unit AE is designed such that the light window allows the unrestricted operation of the optical sensor means required for this.

In the surface area of the touch screen, certain surface structures can be machined into the cover unit AE. If, for example, at certain positions in the shown guided user interface, illustrated function keys are designed, these illustrated function keys can mimic surface structures in shape and size and can thus be operated by touching them .

The first sensor S1 , as described above, detects the covered instrument or control panel BK on which the covering unit is arranged. In addition, the first sensor S1 can deduce what type of covering/sterile covering is being used. The first sensor S1 can be, for example, a reading unit for an RFID (Radio Frequency Identification) element arranged in the covering unit AE. On the RFID (Radio Frequency Identification) element, it is also possible, for example, to indicate the currently carried out disinfection. It can also be provided that the use of the cover unit AE is time-limited. Furthermore, the sterile cover can also have a three-dimensional structure in the area of the touch screen in order to make the graphical operating element tactile and thereby simplify its handling. By means of the recognition of the overlay type, it is possible to selectively influence the user interface displayed on the touch screen. For example, on a cover unit with tactilely identifiable bumps S1B1 , at certain positions on the graphic interface, permanently usable operating elements corresponding to the positions of the bumps can be displayed. In another embodiment, if, for example, only certain areas of the touchscreen are covered with a transparent cover, only said certain areas of the touchscreen are available for display/operation. The cover unit AE is made at least partially transparent, so that the text or colored operating instructions printed on the operating panel BK are only visually visible to the user. Said part of the cover unit AE can be configured, for example, in the form of a transparent plastic cover.

The application of the cover unit AE described above is not limited to the operation panel BK. It is also possible to apply the covering unit AE to a meter and/or a meter part. Especially for control elements that are always displayed at the same position on the touch screen, blind operation is also possible when re-establishing the positioning accuracy of the sterile covering cap, because unlike on a flat touch screen, it is also possible here, for example, by embossing , appropriately changing overlays in certain positions, imitating mechanical tactile buttons and such operating elements.
